Re: The Summer/Fall '09 videocard thread
ATi Linux drivers are crap, Rob? 
Now, when I saw the 24 display setup, I thought that the displays were Dell's 22" displays. However, AMD's demonstration utilized 24 Dell 2408WFP displays, the very same display I am looking at every day… and it looked quite small.
What you're seeing in pictures inside this article is a single PC based on AMD Phenom II 955 processor, Dragon platform and four graphics cards, running X-Plane from Laminar Research using Linux operating system. You've read it correctly, Linux support is out of the box, which is going to make penguin lovers quite happy. Unlike Windows and its limitations due to built-in DRM schemes, Linux has no problems to do a massive multi-scale display experience such as the aforementioned 24 display setup.
The 24 panel setup is running four instances of X-Plane, occupying each CPU core, using the latest beta version which is going to be available soon.
The caveat of avoiding screen overlapping is very interesting. According to AMD people we spoke with, the driver is making a 120 pixel vertical and horizontal adjustment, e.g. rendering each display as 1920+120 pixel horizontally and 1200+120 pixel vertically [2040x1320 pixels], achieving near-perfect alignment.
By rendering those 120 pixels extra, the resolution load was significantly increased for this 24 display setup [12240x5280], i.e. the next-generation GPU from AMD has to render 64.63 million pixels in order to show perspective-corrected 55.29 million pixel image.
But the end result is more than impressive - flying the plane in 12240x5280 resolution is nothing [less than] breathtaking. Even though the banding between the two displays reduces the immersive experience, the fact of the matter is that this technology reduces the cost of multi-monitor technology at least by a factor of five.
You will still have to wait for later in the year to be able to immerse yourself in multiple display setups, but the technology shown here is quite impressive.

Re: The Summer/Fall '09 videocard thread
Their drivers have been getting better. With the drivers that Ubuntu installs for you, I had numerous problems, and were frankly a piece of smurf. For example, my monitor wouldn't go to sleep, and instead just be a black screen with the backlight still on. Also, the display control panel would only reliably show up if you bring it up shortly after logging on, and only once. It also took me... much longer than it should have to get my new monitor working. It would show the desktop at my new resolution, but the monitor was set to use the old resolution, making the desktop overflow the screen boundaries. At one point, X Windows wouldn't even start, but I did eventually fix the issue after enough cursing.
However, I have since discovered that ATI has been updating their drivers quite often, and downloaded the newest driver. Afterwards, my monitor correctly goes to sleep and the displays control panel opens promptly. I haven't tried to change monitors, so I can't comment if they fixed that gorilla of a bug. There is still one major issue that persists, and that's vsync. It works fine for OpenGL, but it doesn't work correctly for X Windows, which means that windows tear. Since I have been able to set my video players to use OpenGL, it hasn't been a major problem. Also, flash plays smoothly and without tearing.
So yeah, still problems but also steadily getting better.

Re: The Summer/Fall '09 videocard thread
Classic- talk up what you got, talk down what you ain't got. NV must be as far behind on DX11 & GT300 as has been rumored...
NVIDIA exec says DirectX 11 won't drive GPU sales
While speaking with analysts at the Deutsche Bank Securities Technology Conference on Wednesday Nvidia's Sr. Vice President of Investor Relations, Mike Hara downplayed the importance of DirectX 11 and its influence on GPU sales. From Xbit Labs:
“DirectX 11 by itself is not going be the defining reason to buy a new GPU. It will be one of the reasons. This is why Microsoft is in work with the industry to allow more freedom and more creativity in how you build content, which is always good, and the new features in DirectX 11 are going to allow people to do that. But that no longer is the only reason, we believe, consumers would want to invest in a GPU.
"Now, we know, people are doing a lot in the area of video, people are going to do more and more in the area of photography… I think that the things we are doing would allow the GPU to be a co-processor to the CPU and deliver better user experience, better battery life and make that computers little bit more optimized.”
(While it's certainly true that the DX11 API itself isn't the only reason users buy new cards, the performance next-generation DX11 hardware will bring in existing DX9 and DX10 games certainly is probably the most defining factor. Hara disagrees though:)
“Graphics industry, I think, is on the point that microprocessor industry was several years ago, when AMD made the public confession that frequency does not matter anymore and it is more about performance per watt. I think we are the same crossroad with the graphics world: framerate and resolution are nice, but today they are very high and going from 120fps to 125fps is not going to fundamentally change end-user experience. But I think the things that we are doing with Stereo 3D Vision, PhysX, about making the games more immersive, more playable is beyond framerates and resolutions. Nvidia will show with the next-generation GPUs that the compute side is now becoming more important that the graphics side."
DX8 & 10, now those were reasons to buy (we had parts first). -9 and -11, no [longer]...

Re: The Summer/Fall '09 videocard thread
ATI Radeon 5870 X2/5850 X2 cards spotted
Now that the 5870 "Cypress" launch is behind them, ATI's engineers are putting the finishing touches on their dual-GPU "Hemlock" boards, which are expected to debut before the end of the year. A couple of shots of the board have hit Xtremesystems.org. In one of the images you can clearly see the 8-pin and 6-pin PCIe power connectors required to power the card.
Meanwhile VR-Zone managed to check out an ATI demo system outfitted with a 5850 X2 GPU running Alien vs Predator DX11. They said the Hemlock board was slightly longer than 5870, perhaps as long as 12" PCB. Performance was "encouraging", although specific frame rates aren't mentioned.

Re: The Summer/Fall '09 videocard thread
Updates for ATi & NV, and an overdue title edit.
AMD’s Radeon HD 5850: The Other Shoe Drops
“For those of you looking for the above and a repeat of the RV770/GT200 launch where prices will go into a free-fall, you’re going to come away disappointed. That task will fall upon the 5850, and we’re looking forward to reviewing it as soon as we can.”
-From our Radeon HD 5870 Review
Today the other shoe drops, with AMD launching the 5870’s companion card: the slightly pared down 5850. It’s the same Cypress core that we saw on the 5870 with the same features: DX11, Eyefinity, angle-independent anisotropic filtering, HDMI bitstreaming, and supersample anti-aliasing. The only difference between the two is performance and power – the 5850 is a bit slower, and a bit less power hungry. If by any chance you’ve missed our Radeon HD 5870 review, please check it out; it goes in to full detail on what AMD is bringing to the table with Cypress and the HD 5800 series.
AMD updated the specs on the 5850 at the last moment when it comes to power. Idle power usage hasn’t changed, but the final parts are now specified for 151W load power, versus the 160W originally given to us, and 188W on the 5870. So for the power-conscious out there, the 5850 offers a load power reduction in lockstep with its performance reduction.
As compared to the 5870, AMD has disabled two of the SIMDs and reduced the core clock from 850MHz to 725Mhz. This is roughly a 15% drop in clock speed and a 10% reduction in SIMD capacity, for a combined theoretical performance difference of 23%. Meanwhile the memory clock has been dropped from 1.2GHz to 1GHz, for a 17% overall reduction. Notably the ROP count has not been reduced, so the 5850 doesn’t lose as much rasterizing power as it does everything else, once again being 15% due to the drop in clock speed.
With the reduction in power usage, AMD was able to squeeze Cypress in to a slightly smaller package for the 5850. The 5850 lobs off an inch in length compared to the 5870, which will make it easier to fit in to cramped cases. However the power connectors have also been moved to the rear of the card, so in practice the space savings won’t be as great. Otherwise the 5850 is a slightly smaller 5870, using the same sheathed cooler design as the 5870, sans the backplate.
...and for those for whom 2.15B transistors is not enough, and who can afford the wait or just favor NV...
NVIDIA's Fermi: Architected for Tesla, 3 Billion Transistors in 2010
The graph below is one of transistor count, not die size. Inevitably, on the same manufacturing process, a significantly higher transistor count translates into a larger die size. But for the purposes of this article, all I need to show you is a representation of transistor count.
See that big circle on the right? That's Fermi. NVIDIA's next-generation architecture.
NVIDIA astonished us with GT200 tipping the scales at 1.4 billion transistors. Fermi is more than twice that at 3 billion. And literally, that's what Fermi is - more than twice a GT200.
At the high level the specs are simple. Fermi has a 384-bit GDDR5 memory interface and 512 cores. That's more than twice the processing power of GT200 but, just like RV870 (Cypress), it's not twice the memory bandwidth.
The architecture goes much further than that, but NVIDIA believes that AMD has shown its cards (literally) and is very confident that Fermi will be faster. The questions are at what price and when.
The price is a valid concern. Fermi is a 40nm GPU just like RV870 but it has a 40% higher transistor count. Both are built at TSMC, so you can expect that Fermi will cost NVIDIA more to make than ATI's Radeon HD 5870.
Then timing is just as valid, because while Fermi currently exists on paper, it's not a product yet. Fermi is late. Clock speeds, configurations and price points have yet to be finalized. NVIDIA just recently got working chips back and it's going to be at least two months before I see the first samples. Widespread availability won't be until at least Q1 2010.
I asked two people at NVIDIA why Fermi is late; NVIDIA's VP of Product Marketing, Ujesh Desai and NVIDIA's VP of GPU Engineering, Jonah Alben. Ujesh responded: because designing GPUs this big is "smurfing hard."
Jonah elaborated, as I will attempt to do here today.
No smurf, Sherlock.
NV is still with the monolithic megachip approach (tho Cypress isn't exactly petite); these things are put in hands years in advance. It would've been difficult if not impossible to go the small-die route this generation.
Both at AT. Pics with both, of course. (Btw, I really like ATI's new full-sheath approach. Also btw, NC, Intel has demoed the first Larrabee- raytracing, no less).

Re: The Summer/Fall '09 videocard thread
From the above, p.7- NV 'fesses up, somewhat.
The RV770 Lesson (or The GT200 Story)
It took NVIDIA a while to give us an honest response to the RV770. At first it was all about CUDA and PhsyX. RV770 didn't have it, so we shouldn't be recommending it; that was NVIDIA's stance.
Today, it's much more humble.
Ujesh is wiling to take total blame for GT200. As manager of GeForce at the time, Ujesh admitted that he priced GT200 wrong. NVIDIA looked at RV670 (Radeon HD 3870) and extrapolated from that to predict what RV770's performance would be. Obviously, RV770 caught NVIDIA off guard and GT200 was priced much too high.
Ujesh doesn't believe NVIDIA will make the same mistake with Fermi.
Jonah, unwilling to let Ujesh take all of the blame, admitted that engineering was partially at fault as well. GT200 was the last chip NVIDIA ever built at 65nm - there's no excuse for that. The chip needed to be at 55nm from the get-go, but NVIDIA had been extremely conservative about moving to new manufacturing processes too early.
It all dates back to NV30, the GeForce FX. It was a brand new architecture on a bleeding edge manufacturing process, 130nm at the time, which ultimately lead to its delay. ATI pulled ahead with the 150nm Radeon 9700 Pro and NVIDIA vowed never to make that mistake again.
With NV30, NVIDIA was too eager to move to new processes. Jonah believes that GT200 was an example of NVIDIA swinging too far in the other direction; NVIDIA was too conservative.
The biggest lesson RV770 taught NVIDIA was to be quicker to migrate to new manufacturing processes. Not NV30 quick, but definitely not as slow as GT200. Internal policies are now in place to ensure this.
Architecturally, there aren't huge lessons to be learned from RV770. It was a good chip in NVIDIA's eyes, but NVIDIA isn't adjusting their architecture in response to it. NVIDIA will continue to build beefy GPUs and AMD appears committed to building more affordable ones. Both companies are focused on building more efficiently.
Also, if you didn't read as you should've
, much of Fermi is architected to a market other than games, and its more demanding requirements, like ECC memory and more.
NVIDIA's architecture is designed to address its primary deficiency: the company's lack of a general purpose microprocessor. As such, Fermi's enhancements over GT200 address that issue. While Fermi will play games, and NVIDIA claims it will do so better than the Radeon HD 5870, it is designed to be a general purpose compute machine.
ATI's approach is much more cautious. While Cypress can run DirectX Compute and OpenCL applications (the former faster than any NVIDIA GPU on the market today), ATI's use of transistors was specifically targeted to run the GPU's killer app today: 3D games.
Intel's take is the most unique. Both ATI and NVIDIA have to support their existing businesses, so they can't simply introduce a revolutionary product that sacrifices performance on existing applications for some lofty, longer term goal. Intel however has no discrete GPU business today, so it can.
Larrabee is in rough shape right now. The chip is buggy, the first time we met it it wasn't healthy enough to even run a 3D game. Intel has 6 - 9 months to get it ready for launch. By then, the Radeon HD 5870 will be priced between $299 - $349, and Larrabee will most likely slot in $100 - $150 cheaper. Fermi is going to be aiming for the top of the price brackets.
The motivation behind AMD's "sweet spot" strategy wasn't just die size, it was price. AMD believed that by building large, $600+ GPUs, it didn't service the needs of the majority of its customers quickly enough. It took far too long to make a $199 GPU from a $600 one - quickly approaching a year.
Clearly Fermi is going to be huge. NVIDIA isn't disclosing die sizes, but if we estimate that a 40% higher transistor count results in a 40% larger die area then we're looking at over 467mm^2 for Fermi. That's smaller than GT200 and about the size of G80; it's still big.
I asked Jonah if that meant Fermi would take a while to move down to more mainstream pricepoints. Ujesh stepped in and said that he thought I'd be pleasantly surprised once NVIDIA is ready to announce Fermi configurations and price points. If you were NVIDIA, would you say anything else?
Jonah did step in to clarify. He believes that AMD's strategy simply boils down to targeting a different price point. He believes that the correct answer isn't to target a lower price point first, but rather build big chips efficiently. And build them so that you can scale to different sizes/configurations without having to redo a bunch of stuff. Putting on his marketing hat for a bit, Jonah said that NVIDIA is actively making investments in that direction. Perhaps Fermi will be different and it'll scale down to $199 and $299 price points with little effort? It seems doubtful, but we'll find out next year.
[p8] Today's launch is strange. I tried to convince NVIDIA to release more information about Fermi but was met with staunch resistance from the company. NVIDIA claims that by pre-announcing Fermi's performance levels it would seriously hurt its existing business. It's up to you whether or not you want to believe that.
Last quarter the Tesla business unit made $10M. That's not a whole lot of money for a company that, at its peak, grossed $1B in a single quarter. NVIDIA believes that Fermi is when that will all change. To borrow a horrendously overused phrase, Fermi is the inflection point for NVIDIA's Tesla sales.
By adding support for ECC, enabling C++ and easier Visual Studio integration, NVIDIA believes that Fermi will open its Tesla business up to a group of clients that would previously not so much as speak to NVIDIA. ECC is the killer feature there.
While the bulk of NVIDIA's revenue today comes from 3D graphics, NVIDIA believes that Tegra (mobile) and Tesla are the future growth segments for the company. This hints at a very troubling future for GPU makers - are we soon approaching the Atom-ization of graphics cards?
..
So... go read the rest.

Re: The Summer/Fall '09 videocard thread
Wow so NV fails the GT200 cause they expected another 3870...lol, do they even try to test ATI's chips or just make wild guesses? You'd think with your top competitor coming out with a new chip, that you'd actually want to investigate it enough to find out the best way to counter it. The sheer arrogance of NV just reeks in that part. Its like waving a juicy steak of market share in front of a teased and injured doberman (ATI). Pretty soon its gonna attack and rip that arm off along with the steak.

Now you can gamble more safely on stocks.
Also, NV is close to betting the farm on the HPC field for its future. Games aren't the focus anymore, and their head of dev relations/ TWIMTBP jumped to AMD. 'Bullet Physics' is AMD's 'Physics on the GPU' rival to PhysX and Havok, and is all open standards-based (e.g. OpenCL). Hard to believe NV will have equal bang/buck on games going forward, with C++, ECC and all baked into huge chips.

Re: The Summer/Fall '09 videocard thread
Nothing is really final unless/until a company goes out of business/is acquired/ leaves a given market (e.g. PowerVR still makes videochips, just not for PCs), and NV's DX11 hardware won't be out for awhile yet. It seems likely ATi'll have the better solution[s] for 3D gaming this gen is about the most one can say at this point, besides 'you kan haz ATI now.' That's better as in value- NV's best may still be faster as it ought, it does have 40% more transistors- but that can't come cheap. Bang/buck will likely favor ATI.
NV's do look very promising if you're putting together a HPC supercomputing cluster to do seismographic work, but that's not most of us.

Re: The Summer/Fall '09 videocard thread
First DirectX 11 benchmark released
Unigine Corp is the first to release a synthetic DirectX 11 benchmark. Dubbed "Heaven", the benchmark is based on the company's Unigine game engine with full support for OpenGL, DX9, DX10, and DX11.
The developer says tessellation is used extensively to add detail to the game environment "almost free of charge in terms of performance". You can see side-by-side comparisons in this Youtube video:
[embedded player]
To download the heaven benchmark, click here. Keep in mind that you'll need DX11 hardware to see tessellation in action. (Spotted on Bright Side of News)
Then you can bench your ATi cards against your... um... ATi cards. 
Oh well, you can see some pr3tty meanwhile. And it'd be nice to see some lesser tesselation via a DX10.1 render path, but that may be awhile, if it's done at all. Selling the new hawtness matters most. :raspberrymax:
