GTX 480 benchmark video

[nogojoe]

very disappointing. six months late to the party and only eclipses its competition using tessellation.

[cgbeige]

ya, and no developer of 3D apps is going to use tesselation since it's a DirectX only thing and doesn't make any sense to use in 3D work.

Someone working for Nvidia is crying tonight, somewhere, alone.

Everyone else working for Nvidia is playing games at home on a new ATI card tonight.

[DuttyFoot]

they finally released some more info on the gtx cards. These card needs at least a 300W power supply to run.

We're only a week away (http://www.engadget.com/2010/02/22/nvidia-geforce-gtx-480-and-gtx-470-fermi-cards-launching-march-2/) from their grand unveiling, but already we've got word of the specs for NVIDIA's high end GTX 480 and GTX 470 cards (http://www.engadget.com/2010/03/06/nvidia-gtx-480-makes-benchmarking-debut-matches-ati-hd-5870-per/). Priced at $499, the 480 will offer 480 shader processors, a 384-bit interface to 1.5GB of onboard GDDR5 RAM, and clock speeds of 700MHz, 1,401MHz, and 1,848MHz for the core, shaders and memory, respectively. The 470 makes do with 446 SPs, slower clocks, and a 320-bit memory interface, but it's also priced at a more sensible $349. The TDPs of these cards are pretty spectacular too, with 225W for the junior model and 295W for the full-fat card. Sourced by VR Zone, these numbers are still unofficial, but they do look to mesh well with what we already know of the hardware, including a purported 5-10 percent benchmarking advantage for the GTX 480 over ATI's HD 5870 (http://www.engadget.com/2009/09/23/ati-radeon-hd-5870-blazes-onto-the-scene-receives-approving-nod/). Whether the price and power premium is worth it will be up to you and the inevitable slew of reviews to decide.

GeForce GTX 480 : 480 SP, 700/1401/1848MHz core/shader/mem, 384-bit, 1536MB, 250W TDP, US$499

GeForce GTX 470 : 448 SP, 607/1215/1674MHz core/shader/mem, 320-bit, 1280MB, 225W TDP, US$349

* The intended GF100 has 512 SP clocked at 725/1450/1050MHz with 295W TDP. It should still be released in the future but just not now. For this launch, GTX 480 has 480 SP with clocks lowered to 700/1401/1848MHz at 250W TDP.

Internal benchmarks reveal that GeForcehttp://images.intellitxt.com/ast/adTypes/2_bing.gif (http://vr-zone.com/articles/nvidia-geforce-gtx-480-final-specs--pricing-revealed/8635.html#) GTX 470 is some 5-10% faster than Radeon HD 5850 and similiar for GeForce GTX 480 over the Radeon HD 5870. Interestingly, the TDP of GeForce GTX 480 is almost similar to Radeon HD 5970 which is a dual GPU card. Interestingly, our sources revealed that there are indeed plans for dual Fermi cards and the TDP of the card is probably gonna be mind blowing.

A 300W power supply in a system with one of those cards probably wouldn't even boot, not enough power to run anything else. I would imagine you're going to need at least a 600 - 700W power supply. The HD 5870 has a TDP of like 188W and that requires at least a 500W power supply.

[DuttyFoot]

At our office we ordered a system to run gtx 285 cards in sli mode. the case came with two 1400 w power supplies. the second one was a backup. I guess something like that would do well for the new cards.

In case you guys haven't checked, the new nvidia drivers that replaces the 196.75 driver has been released. Its driver 197 for both quadro and geforce cards. About a week ago the new 196.75 driver was causing the fan on the cards to stop moving which caused the gpu to burn up.

I wouldn't be so quick to pass that judgment :) The tesselation uses the same methods as smooth mesh preview in Maya and Turbosmooth in Max and it's all supported through FBX including subdiv holes, creasing etc.

I've got a custom tools suite setup that uses the DX11 SDK to drop out a mesh using Smooth Mesh Preview, run the SDK to convert it to an sdk mesh, convert all the textures, animation etc and then load up the SDK viewer so I can tesselate in real time for the detail I want. I could see people using this more for real time previz of tesselation considering you probably don't want to tesselate up to millions in the viewport or fire off preview renders when you can preview subdivision levels in real time.

I'd assume the next pro level cards will support OGL and DX11 much like previous were OGLand DX9/10.

wow that would be awesome to get smooth mesh previews with no performance hit.

hopefully something like that would actually work, unlike ATI's maya tesselator plugin

Welcome to the future of GPU's :) Ideally you'd want to see this in a viewport of a 3D app where the tesselation is put on the card until you need to go to render and then the renderer just uses the SMP options to subdivide up to the render level mesh. The DX11 SDK viewer is actually pretty decent but it takes some work to get things like lights and other bits working plus it's not really meant to be a full scene viewer so I just use it for a single character.

Is any of this related at all to Nvidia's use of CUDA for OpenCL?

I vaguely recall reading an article about Adobe's new Mercury playback engine taking advantage of Nvidia's CUDA technology and was curious if it had any involvement to what you described on a similar scale.

Pardon the question if it seems silly as I'm not that technically minded.

Nope, this has nothing to do with CUDA or OpenCL as it's all part of DirectX 11 from Microsoft. The subdivision uses the same catmull-clark subdivision that Maya uses but rather than subdivide on the CPU it does it via the Compute Shader on the GPU which is lightning fast. This tech is available on both Nvidia (still waiting for launch date) and ATI hardware that supports DX11 and does not require CUDA, OpenCL or any of that tech.

So the GTX480 and 470 were officially released the other day. Was looking for some tests to see how these cards run with 3D programs. So far all I've seen are gaming benchmarks, and those have not been too impressive. But I am not a PC gamer, so I don't care about that too much.

I'd be curious to see if with Nvidia's historically better drivers, would make these cards translate to better performance in 3D apps than ATi's offerings.

The average performance increase vs. the 5870 with AA enabled is roughly 15% (on extremesystems they took all the benchmarks from various different reviews and averaged the results), with AA disabled about half that.

However, with tesselation turned on, the 480 in some cases even approaches or exceeds the 5970's performance. And overall, its minimum framerates are more stable and higher than those of the 5870.

Out of curiosity I read up on all of that even though it doesn't matter much to me. Only an Nvidia card gives me GPU-accelerated physics in Softimage and GPU-accelerated rendering in Octane and hopefully soon in mental ray iray. Photoshop CS5 will use CUDA as well as far as I know.

[gawl126]

All the reviews have a couple things in common:

-runs too hot
-uses too much power
-too loud on higher usage

EDIT: Here are a few articles that ran Cinebench:

No - PS CS5 has some tweaks to its existing GPU drawing that's in CS4, which is not limited to CUDA cards. It works on either ATI or Nvidia cards (I'm a beta tester).
