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.

Oh great, a whole other sku to lose another billion a year with. Wonderful. Any word on the new costs of the bigger cpu and expensive capacitors and vrm upgrades ?Ahh, nevermind, heck, this ain't a green greedy monster card, screw it if they lose their shirts making it - I mean there's no fantasy satisfaction there.
Get back to me on the nvidia costs - so I can really dream about them losing money.

I am not sure about you guys but NVIDIA has problems with their drivers as well. I have a 9400GT and a 8800 GTS in my machine and the new drivers can't make the two work well enough for my computer to come out of hibernation with out Windows XP crashing every so often. This use to work just fine before I upgraded the drivers to the latest version.FishTankX - Thursday, April 2, 2009 - link

There it is again, 30 watts less idle for nvidia, and only 3 watts more in 3d. NVIDIA WINS - that's why they left it out - they just couldn't HANDLE it....So, if you're 3d gaming 91% of the time, and only 2d surfing 9% of the time, the ati card comes in at equal power useage...
Otherwise, it LOSES - again.
I doubt the red raging reviewers can even say it. Oh well, thanks for posting numbers.

Can anyone confirm whether or not the heatsink/fan has been altered between the 4870 and the 4890? I'm interested to know if the decreased temps of the higher clocked 4890 are due in part to a better cooling mechanism, or strictly from a respin/binning.Warren21 - Thursday, April 2, 2009 - link
Yes, the cooler has been slightly revised. I believe it's a combination of both. I'll admit I'm a bit disappointed AT didn't explore the differences between the HD 4870 and the 4890 more in-depth.Comparisson:

"It looks like NVIDIA might be the marginal leader at this new price point of $250." you wroteBut looking at your own benches..
Since you run 3 resolutions of your benches, lets reasonably declare that the card that can win 2 or more of them "wins" that game. In that case 4890 wins over 275 in: COD WaW, Warhead, Fallout 3, Far Cry 2, GRID, and Left 4 Dead. 275 wins over 4890 in Age of Conan. Either with AA or without the results stay the same.
The only way I think you can contend 275 has an edge is if you place a premium on the 2560X1600 results, where it seems to edge out the 4890 more often. However, it's often at unplayable framerates. Further I dont see a reason to place undue importance on the 2560X benches, the majority of people still game on 1680X1050 monitors, and as you yourself noted, Nvidia released a new driver that trades off performance at low res for high res, which I think is arguably neither here nor their, not a clear advantage at all.
Even at 2560 (using the AA bar graphs because its often difficult to spot the winner at 2560 on the line graphs), where the 275 wins 5 and loses 2, the margins are often so ridiculously close it essentially a tie. 275 takes AOC, COD WaW, and L4D by a reasonable margin at the highest res, while the 4890 wins Fallout3 and GRID comfortably. Warhead and Far Cry 2 are within .7 FPS although nominally wins for 275. Thats a difference of all of 3-2 in materially relevant wins, or exactly 1 game. But keep in mind again that 4890 is fairly clearly winning the lower reses more often, and to me it's wrong to state 275 has the edge.

The funny thing is, if you're in those games and constantly looking at your 5-10 fps difference at 50-60-100-200 fps - there's definitely something wrong with you.I find reviews that show LOWEST framerate during game when it's a very high resolution and a demanding game useful - usually more useful when the playable rate is hovering around 30 or below 50 (and dips a ways below 30.
Otherwise, you'd have to be an IDIOT to base your decision on the very often, way over playable framerates in the near equally matched cards. WE HAVE A LOT OF IDIOTS HERE.
Then comes the next conclusion, or the follow on. Since framerates are at playable, and are within 10% at the top end, the things that really matter are : game drivers / stability , profiles , clarity, added features, added box contents (a free game one wants perhaps).
Almost ALWAYS, Nvidia wins that - with the very things this site continues to claim simply do not matter, and should not matter - to ANYONE they claim - in effect.
I think it's one big fat lie, and they most certainly SHOULD know it.
Note now, that NVidia - having released their, according to this site, high resolution driver tweak for 2560xX , wins at that resolution, the review calmly states it does'nt matter much, most people don't play at that resolution - and recommend ati now instead.
Whereas just prior, for MONTHS on end, when ati won only the top resolution, and NVidia took the others, this same site could not stop ranting and raving that ATI won it all and was the only buy that made sense.
It's REALLY SICK.
I pointed out their 30" monitor for ATI bias months ago, and they continued with it - but now they agree with me - when ATI loses at that rezz... LOL
Yeah, they're schesiters. Ain't no doubt about it.
Others notice as well - and are saying things now.
I see Jarred is their damage control agent.

Why not just use RivaTuner or ATI Tool to underclock OC'd cards?Jamahl - Thursday, April 2, 2009 - link
How can the conclusion be that the 275 is the leader at the price point? The benchmarks are clearly in favour of the 4890 apart from the extreme end 2560x1600.
