GTX 285 Mac Edition: The Best for OS X? (title edit)
One pager by Anand.
As I mentioned in an earlier post, I’m working on a review of EVGA’s GeForce GTX 285 Mac Edition. I just finished writing a section about GPU memory usage under OS X (since the 285 has a hefty 1GB frame buffer) and thought I’d publish it as a standalone before the review is done. I've been considering doing more things like this in the future, where you get pieces of a review as I finish them before the full thing is done. Let me know what you think.
..
Honestly, one of the biggest uses for a new graphics card under OS X is having additional video memory.
The contents of each window and the windows themselves are drawn by the GPU and stored in video memory. Previous versions of OS X either drew windows in system memory and then composited all of them in video memory, or did everything in system memory and just outputted the final scene to the video card. Ever since OS X 10.4, the entire drawing and display process happens on the GPU and in video memory. Ars Technica’s John Siracusa has an excellent explanation of the whole process.

And as promised, the full article is now up.
EVGA's GeForce GTX 285 Mac Edition: The Best for OS X?
Upgrading anything other than memory or hard drives in a Mac is ridiculously frustrating. Most of Apple’s machines use mobile CPUs soldered on to the motherboards, which makes swapping chips an impossible affair. And the ones that don’t use mobile chips have other supermodel quirks associated with them, like being lidless.
Upgrading Mac video cards has always been an unreasonable pain. Mac versions of PC GPUs have always been ridiculously overpriced and taken far too long to come out. Apple still sells an ATI Radeon X1900 XT upgrade kit for the Mac Pro, for $399. Do I even need to point out how disappointing that is?
Lately Apple has been getting a bit better with GPU releases. The 8800 GT and even more recently, the Radeon HD 4870 have both been build-to-order GPU options directly from Apple. Even more awesome is that once Apple officially supports a conventionally PC video card, it just takes one user to dump the ROM from the Mac version and now we all have a way of hacking PC cards to become Mac editions.
In a completely surprising move however, EVGA has released a GeForce GTX 285 Mac Edition. Prior to this release, all 3rd party video card upgrades were branded either by ATI or NVIDIA - Apple doesn’t really support the upgrade market the way the PC industry does. What EVGA has done is given Mac users a very high end GPU option that they can buy from Apple.com or through a handful of other online vendors.
Why do you even need a GeForce GTX 285 Mac Edition? The hardware is identical to what you get (for $100 less) when you buy a PC card, the difference is in the packaging and firmware.
These cards are only useful in the Mac Pro, but the standard video card in any Mac Pro doesn’t require any additional PCIe power connectors. If you upgrade to a more power hungry video card, you’ll need one or two cables that connect the small PCIe power connectors on the Mac Pro’s motherboard to the connectors on the video card itself. These come in the GTX 285 Mac Edition box.

We flashed a PC HD 4870 and got it to work in a Mac Pro. ATI sells the adapter cables as spare parts. So far, it's running great. Hopefully the price discrepancy will diminish, and/or more companies will offer Mac versions of their cards. Of course, if MS and others would quit dicking around with BIOS and switch to EFI already, this wouldn't be as big an issue. Too much pain is endured in the name of backward compatibility.
I'm more concerned about the notebook state of affairs. I've been holding out on replacing my first-gen MacBook for Arrandale, but now it appears that Intel is pulling the biggest of dick moves and integrating the integrated GPU into the CPU and has designed the architecture is such a way as to exclude third parties such as NVIDIA from making competing chips like the 9400M. I can't help but think this is deliberate given the current lawsuit between them. I'm wondering if I wouldn't be better off getting the current model. The CPU performance won't be as good, but it appears I'll do much better with the 9400M than whatever crap Intel will be bundling with Arrandale. I guess if the graphics performance does suck, I can hopefully pick up one of the current models at a discount.
Are we going to wind up with NVIDIA making x86 chipsets just so they can compete? It would be cool if AMD's mobile processors weren't so terrible. It seems we're heading for an all-in-one approach on a smaller scale that will mean essentially buying a complete system-on-a-chip from a single vendor.

Re: GTX 285 Mac Edition: The Best for OS X? (title edit)
AMD/ATi is putting a big effort into better mobile CPUs. Their newest core logic, with decent graphics, is making its debut, but, I think, isn't 100% yet (haven't read AT's article). NV claims to have rights to make x86 CPUs and be designing one, but Intel disputes the license; most think the same, and Intel won't give them one now. Intel is pulling GPU functions into the CPU as they make their renewed grab for the graphics market (Larrabee). IIRC NV is trumpeting ION 2 as the best thing since [..].
It's a complex situation and changing fast. I'll keep an eye or two peeled for related items.

They really need to if they want to survive. The market is heading toward notebooks (and netbooks) in a big way. AMDs offerings have either been too slow and/or too power hungry or too hot compared to Intel's. But even then, just because I'm using an AMD CPU doesn't mean I necessarily want ATI graphics. Hopefully NV will have the funds to hire good engineers to make decent CPUs.
Unfortunately this means OEMs won't be able to choose the best from each and will have to take the pros and cons of each.

Re: GTX 285 Mac Edition: The Best for OS X? (title edit)
Last I checked ATi was ahead in the integrated graphics area. If the 4870 is OK by you...
NV making a CPU, and being able to sell it, are two different things. Intel holds the x86 IP. AMD's license goes back many years.

Yeah, it will be interesting to see what becomes of the current lawsuit.
Again, the problem coming down to AMD being unwilling or unable to make mobile integrated chipsets that work with Intel CPUs. I'm just not sure why Intel is spurning NV in this manner - they have next to no expertise in this area. One would think they would welcome NV's help in bolstering their platform.

I'm not aware of AMD chipsets being unable to support Intel CPUs, but I haven't paid close enough attention to the mobo market lately to say what mobos have/are/will be made with AMD chipsets and their associated sockets. I can't think of a reason chipsets by one couldn't support the other's CPUs, but Intel's market dominance the last couple of years may've resulted in an abundance of Intel boards such that it makes little sense to make AMD-chipset boards supporting Intel sockets. It's not a reciprocal situation, with a bunch of Intel boards supporting Phenom.
Bad blood between Intel and NV goes back at least to Jen-Hsen's 'can of whoop-ass' remark. NV and MS goes back much further, to NV screwing MS over Xbox 1 chip prices and continuing since. NV is a very... 'aggressive' company, and their bridge-burning hubris comes home to roost when things go badly a la exploding chips, screwing OEM partners when losing money etc. NV and Intel have been on a collision course since Larrabee surfaced quite some time back.
In any case, AT got an early look at AMD's latest, albeit a bit too early...
It seems that in our rush to secure this motherboard that we overlooked one very important aspect during our investigation. It turns out the driver set we were privy to for testing is an early beta set missing several important driver features while AMD is still optimizing performance. We encountered no stability problems running a multitude of benchmarks, but the lack of features and optimizations preclude us from publishing a meaningful first look, especially for those looking to use this new platform in an HTPC or SFF gaming system. Of course, there were discussions with AMD explaining some of the early problems we ran into during testing. As such, AMD requested that we wait until the drivers are mature and based on early test results we will heed their requests.
What we can do today is discuss some early observations and provide a couple of results that are indicative of the board's capability with an early BIOS and a quick look at Blu-ray playback results. First off, even with less than stellar drivers, the board's performance was equal to or better than the current 780G/790GX motherboards and it will only improve. How much is up for discussion as AMD designated the new chipset just a half point higher for a reason.
The graphics core in the 785G is upgraded from the HD3200/3300 utilized in the 780G/790GX to the HD4200. The primary difference between the cores is that the HD4200 fully supports DX10.1, Unified Video Decoder 2.0 (UVD), hardware accelerated picture in picture capabilities, dynamic contrast, HQ video scaling, hardware accelerated video transcoding, and full Powerplay support. The graphics core still runs at 500MHz (in current form) and at least in our particular sample, we were able to reach 1057MHz without too much trouble.
What does all this mean? For one, thanks to the HD4200, AMD finally offers multi-channel LPCM audio output plus additional hardware video accelerated functions. As far as performance is concerned, expect a 5%~ 15% performance increase in games. That sounds impressive, but playing the Sims 3 at 1024x768 with medium quality settings resulted in an average framerate increase from 23.9fps on the 780G to 26.1fps on the 785G with alpha level drivers. The biggest difference occurred in minimum frame rates with an increase from 12fps on the 780G to 15fps on the 785G. Otherwise, the GPU capabilities are fine for casual gaming (Plants vs Zombies) and flash based games.
For those not tracking this, NV talked down 10.1 support as they didn't have it, but come October NV chips, albeit lower-end, will support 10.1. The smack talk is ending... trouble is, ATi should have DX11 chips out by then.

Netkas' has a kext called 'natit', which reportedly allows ordinary PC cards to work on the Mac Pro without flashing. Might be something worth considering in the future. You eliminate the risk associated with flashing, and you can still use the card in a PC.
Of course, if MS and others would quit dicking around with BIOS and switch to EFI already, this wouldn't be as big an issue. Too much pain is endured in the name of backward compatibility.
Well, it's ultimately APPLE's job to address the needs of its customers -- not third parties. Especially since there's nothing in the EFI specification that prevents regular cards from working. If Apple followed the spec, there wouldn't be a problem.
The fact is that, with the exception of a few server boards, EFI is not well supported on the Mac or PC. Hardware designers seem to agree that the benefits are not worth the added complexity. Here's EFI's main benefits:
1) Overcomes the real-mode restriction (This is probably the most significant)
2) High-level platform-independent drivers
3) pre-boot mouse-driven GUI.
Apple uses exactly zero of these to their advantage, and they're not alone. EFI introduces a significant degree of unwarranted complexity for system programmers --So much so that most (if not all) OSes supporting EFI do so in the most minimalist way possible. They (Apple, the Linux community, HP, etc...) treat EFI as just another bootloader, because that's what makes the most sense. That's not to say that EFI will never catch on, but for the time being, it's pointless, imo

The GTX 285 also works in the Mac Pro without flashing, iff you have another NVidia card in there to get the Mac to load NV drivers on startup.
Good point about EFI, it's a shame nobody really uses it. I was hopeful a few years ago that the EFI switch would lead to overclockable Macs and stuff but the OSX86 project brought us that first!

It'll catch on, but even I'm surprised at how long it's taking. It's several years old now and barely has a toehold in the PC space. Rare for an Intel tech.

Re: GTX 285 Mac Edition: The Best for OS X? (title edit)
Well flashing has come a long way since the old days. Prolly much better now with the x86 hardware. I've noticed a lot better success stories from them but its just not getting the buzz like it used to now with Apple offering better GPUs. We need more good flashing stories in the Hardware Hacking forum here of more recent boards
.
I wouldn't totally rule out AMD mobile GPUs. Aside from non existant drivers, in favor of the makers patching their own, i've not had terrible performance. The 3470 in my mom's Vaio has been a steady performer whenever i've had the chance to use it. Beats out some of the similar 8 series chips from NV even if its a low end. I wouldn't mind buying another laptop with ATI GPUs that have a bit more power, as long as Mobility Modder still works or ATI finally gets smart and just extends desktop drivers to cover mobility. Heck i'm using desktop 3470 drivers right now anyways thx to modder.

The GPUs from AMD aren't the problem. My only complaint on the PC side is that their Linux drivers suck. But the Turions have never been good compared to Intel's mobile offerings.

Re: GTX 285 Mac Edition: The Best for OS X? (title edit)
Have you tried them lately? ATi's been working steadily on the Linux side... anyway Turion's basically dead, replaced for some time by the Puma/Griffin platform. I'm scoping out how it performs, but comparisons aren't easy to come by. Chipset support has lagged, one reason it's good AMD's doing its own, pretty well and improving. Better still as they leapfrog down to 45nm and below.
More as I can dig up solid info.
