ATI Radeon HD 4890 vs. NVIDIA GeForce GTX 275

CUDA - Oh there’s More
Oh I’m not done. Other than PhysX, NVIDIA is stressing CUDA as another huge feature that no other GPU maker on the world has.
For those who aren’t familiar, CUDA is a programming interface to NVIDIA hardware. Modern day GPUs are quite powerful, easily capable of churning out billions if not a trillion instructions per second when working on the right dataset. The problem is that harnessing such power is a bit difficult. NVIDIA put a lot of effort into developing an easy to use interface to the hardware and eventually it evolved into CUDA.
Now CUDA only works on certain NVIDIA GPUs and certainly won’t talk to Larrabee or anything in the ATI camp. Both Intel and ATI have their own alternatives, but let’s get back to CUDA for now.
The one area that GPU computing has had a tremendous impact already is the HPC market. The applications there lent themselves very well to GPU programming and thus we see incredible CUDA penetration there. What NVIDIA wants however is CUDA in the consumer market, and that’s a little more difficult.
The problem is that you need a compelling application and the first major one we looked at was Elemental’s Badaboom. The initial release of Badaboom fell short of the mark but over time it became a nice tool. While it’s not the encoder of choice for people looking to rip Blu-ray movies, it’s a good, fast way of getting your DVDs and other videos onto your iPod, iPhone or other portable media player. It only works on NVIDIA GPUs and is much faster than doing the same conversion on a CPU if you have a fast enough GPU.
The problem with Badaboom was that, like GPU accelerated PhysX, it only works on NVIDIA hardware and NVIDIA isn’t willing to give away NVIDIA GPUs to everyone in the world - thus we have another catch 22 scenario.
Badaboom is nice. If you have a NVIDIA GPU and you want to get DVD quality content onto your iPod, it works very well. But spending $200 - $300 on a GPU to run a single application just doesn’t seem like something most users would be willing to do. NVIDIA wants the equation to work like this:
Badaboom -> You buy a NVIDIA GPU
But the equation really works like this:
Games (or clever marketing) -> You buy a NVIDIA GPU -> You can also run Badaboom
Now if the majority of applications in the world required NVIDIA GPUs to run, then we’d be dealing in a very different environment, but that’s not reality in this dimension.

the 270 is a 285 nerf, so what?your point is?
SiliconDoc - Thursday, April 23, 2009 - link
The other point is, when you've been whining about nvidia having a giant brute force core that costs too much to make, and how that gives ati a huge price and profit advantage ( even though ati has been losing a billion a year) , that when ati make a larger core and moer expensive breadboard and cooler setup standard for their rebrand, you point out the greater expense, in order to at least appear fair, and not be a red raging rooster rooter.Got it there bub ?
Sure hope so.
Next time I'll have to start charging you for tutoring and reading comprehension lessens.

Uh, for you, the mentally handicapped, the point is since ati made a rebrand, call it a rebrand, especially when you've been screeching like a 2 year old about nvidia rebrands, otherwise you're a lying sack of red rooster crap, which you apparently are.Welcome to the club, dumb dumb.
I hope that helps with your mental problem, your absolute inability to comprehend the simplest of points. I would like to give you credit and just claim you're being a smart aleck, but it appears you are serious and haven't got clue one. I do feel sorry for you. Must be tough being that stupid.

Just that one "rebadge" comes with 3 million extra transistors; deal with it.SiliconDoc - Monday, April 6, 2009 - link
" Because they’re so similar, the Radeon 4870 and 4890 can be combined together for mix-and-match CrossFire, just like the 4850 and 4870."Yep, that non rebadge. LOL

To see AO applied to FEAR. Boris Vorontsov developed the directx mod long ago!

Oh sorry, forgot forced SLI profiles, and I don't want to fail to mention something like EVGA's early release NVidia game drivers for games on DAY ONE. lolAww, red rover red rover send the crying red rooster right over.
Did I mention ati lost a billion bucks two years in a row for amd ?
No ?
I guess Dewreck and anand forgot to mention the larger die, and more expensive components on the 790 ati boards will knock down "the profits" for ati. LOL Yeah, awww... we just won't mention cost when ati's goes up - another red rooster sin by omission.
I ought to face it, there are so many, I can't even keep up anymore.
They should get ready for NVidia stiffing them again, they certainly deserve it - although it is funny watching anand wince in text as he got addicted to Mirror's Edge - then declared "meh" for nvidia.
lol - it's so PATHETIC.

what the hell are you talking about?SiliconDoc - Thursday, April 23, 2009 - link
You proved you can't read and comprehend properly on the former page, where I had to correct you in your attempt to whine at me - so forget it - since you can't read properly ok nummy ?SiliconDoc - Monday, April 6, 2009 - link
Ahh, thank you very much. lolNVIDIA wins again !
rofl
I'm sure the ati card buyers will just hate it...but of course they are so happy with their pathetic "only does framerates, formerly in 2560 for wins, now in lesser resolutions for the win"
It just never ends - Cuda, PhySx, Ambient Occlusion, bababoom, the vReveal, the game presets INCLUDED in the driver, the ability to use your old 8 or 9 Nvidia card for PhysX or Cuda in a xfire board with another NVidia card for main gaming ...
I know, NONE OF IT MATTERS !
The red rooster fanbois hate all of that ! They prefer a few extra frames at way above playable framerates in certain resolutions depending on their fanboy perspective of the card release (formerly 2560 now just lower resolutions)- LOL that they cannot even notice unless they are gawking at the yellow fraps number while they get buzzed down in cold blood in the game.
Ahhh, the sweet taste of victory at every turn.
