Next Generation D10U GeForce Cards Specs Unveiled

**Uraloserface101** · 05-21-2008, 04:11 PM

Few details have been leaked regards Nvidia's upcoming next-generation graphics core, codenamed D10U.

D10U will make its first debut in 2 separate graphics cards; the high end GeForce GTX 280 (D10U-30) and the lower spec GeForce GTX 260 (D10U-20). For this new generation, Nvidia redesigned its unified stream(shader) processors to perform 50% faster than the ones used in the G90 series. GeForce GTX 280 will feature 240 of those redesigned unified stream processors and GeForce GTX 260 will carry 192.

GTX 280 ships with a 512-bit memory bus capable of supporting 1GB GDDR3 memory and GTX 260 alternative has a 448-bit bus with support for 896MB.

The new D10U series will deliver all the features found in the current G90 series and, surprisingly, it won't support DirectX 10.1. This might seem like lagging behind AMD's upcoming Radeon HD 4000 series, but it may be in the best interest of GeForce 8 and GeForce 9 cards owners that Nvidia utilizes its market position to protect them from being outdated over some minor DirectX changes.

D10U series will incorporate the PhysX stream engine into its shader engine, but no more info is available right now.

The new cards are scheduled for launch on June 18, 2008.

Sweet Jesus it's huge!!

No true specs on it yet. Boy oh boy do I want to see the specs.

The GTX280 will require one 8-pin and one 6-pin connector, while the GTX260 will suffice with two 6-pin connectors. GTX280 sports a 512-bit bus and 1GB GDDR3 memory, while GT260 has to settle for 448-bit and 896MB GDDR3 memory as NVIDIA will disable two memory chips and two clusters of shaders.

GTX280 will have a full setup of shaders, meaning all 240 till be active, while GTX260 has 192 shaders. This may sound like a lot already, but NVIDIA also claims that the shaders themselves are up to 50% faster than the shaders of G80/G92.

Alas, there's no DirectX 10.1 support, which is kind of poor when you think about it, even if there are extremely few games (any?) out there that actually uses it. Instead NVIDIA has put a lot of work into incorporating the support for its newly acquired PhysX engine, but we still have little to no information about the exact works of that.

There is currently one game that "uses" DX10.1 - Assassins Creed. (and even that the dev is pulling it)

Those who buy for DX10.1 support this gen are going to give up a lot for it.
