OpenCL is the new GPU-based computing thing. Like CUDA.

You knew that was tongue-in-cheek, right? I've been posting about OpenCL for ages. v1.0 has been out for some time already.

Also it's GP-GPU (General Purpose GPU), and includes ATi's Brook+ API/Stream tech, for those ignoring those posts.

NV hasn't fielded a DisplayPort card yet, to my knowledge.

And they will not field a displayport card until there are more than 3 devices to utilize it.

Funny how ATi manages to implement it. They're making money, too, unlike NV these days (HP's had even mo' exploding chips). Just toss in a $2 adapter.

Forwards compatibility FTW.

Nothing really high end though.

Now, if this were a 295, then I'd be a-really excited. :mariomax:

You need 2.8 billion transistors eating more watts and making more heat than anything extant for Crysis on a 30" CD?

Yes. Yes, you do.

But the 295 would require OS X SLI drivers, wouldn't it?

It would, indeed.  295 --> "SLI."  285 --> "wake me up when we get there."  (1200W PSUs aside).

Just a miscommunication.  I'm only interested in an SLI (or even crossover) driver for OS X -- Even if it debuts in a product I have no intention of buying (e.g. the 295).  Even if it doesn't work on previous-generation cards (e.g. the 8800), I know that I'll at least have something to look forward to.

It's nice, but expensive. Too bad Apple won't offer it as a CTO option.

'PureVideo HD technology' is mentioned, but I don't remember anything but the 9400m listed as being enabled for HD.264 accel in Snow Leopard. It's the same chip; they really should, just for image tuning reasons.

That's good news, though a MP (or i7 in my case) is fully capable of tackling any h.264 file -- even in vanilla Quicktime.

What's so important about h.264? Why does it seem to overshadow everything else? And is this decoding or encoding?

240 cores of OpenCL goodness. Yummy.

Because H.264 is the codec of choice for Bluray.  Faster H.264 decoding means better quality and better upscaling  on higher than 1080p monitors.

H.264 is a very high quality, very highly compressed codec. The appearance of dedicated chips for HD and some lesser decode duties, along with what they do, is detailed nicely here. You can get a decent idea of the issues and the amount of offloading, reflected in decreased CPU utilization from it.

Worth mentioning is that the new GPGPU techs are bringing apps to greatly speed video encode/transcode duties.

ah. bluray. When will the mac support it?

What kind of load are we talking about anway?

I would not hold my breath for Apple Blu-Ray support; as that clearly cuts into the iTunes profit.  I'm not entirely sure that Blu-Ray will even last that long.  With the ever increasing pipes being offered to our houses; the instant gratification of movies on demand and iTunes/AppleTV is probably going to win out.
