post #121 of 326
Akatsuki No Tobi has a very valid point about DX10 lifting (at least partially) the CPU from being a bottleneck. One of the biggest differences between DX9 and DX10 is that DX10 will greatly reduce the number of draw calls made to the CPU.

DX10 will make it far less CPU intensive to render large, complex scenes (think of the jungle foliage in FarCry, or any 'wargame' that requires the drawing of massive battlefield scenes with many multiples of troops and items) by instructing the GPU to draw the same element multiple times in different places without requiring the CPU to intervene. These multiples are kept from looking completely identical through the use of texture arrays.

These techniques will without doubt reduce CPU overhead during graphics intensive operations. While it will not completely eliminate the CPU from being a bottleneck in all situations, it certainly takes a great amount of the 'heavy lifting' off the CPU's shoulders.

SWEEEEETTTT!!!

Looking at this news post in our forum, there is a rumor coming out from the websites in China currently that AMD is planning to launch R600 on 8th or 9th March and be officially named as Radeon X2K series. The mass production silicon is expected to be still at A12 for the R600 cards at launch.

It seems like ATi has successfully taped out a A15 silicon that is able to work at 1GHz probably we can hope to see another series of R600 cards with higher working clocks in the near future. The article suggests ATi's next generation R680 is scheduled for Q3 launch but suggested that NVIDIA will have G81 and the next gen. GPU ready to compete.

According to our sources but still a rumor revealed R600 as X2800 series. There are 2 variants for XTX; 1GB and 512MB. X2800XTX runs at 750MHz core, 2.2GHz memory, 512-bit memory interface and GDDR4 while XT runs at 600MHz core, 1.8GHz memory, 512-bit memory interface and GDDR3.

nVidia 8800GTX:
575MHz Core Speed, 1800MHz Memory Speed, 768MB of GDDR3 with 384-Bit Memory.

AMD/ATi X2800XTX:
750MHz Core Speed, 2200MHz Memory Speed, 1024MB of GDDR4 with 512-Bit Memory.

If that is all true, I'll have to wait and see the 80nm G80 and it's specs to decide. Awesome, if I get an X2800XTX and an Asus Commando ROG that'll set mind blowing Benchmarks.

Imagine the insane bottlenecks that would occur with Crossfired R600s. I think DX10 will definitely be required to relieve the bottlenecks without getting mind blowing overclocks for the CPU.

And I think all the agony I went through of forcing myself not to get an 8800 GTX is about to be well payed for.

The R600 is supposed to be the heaviest card ever made, and both the 8800 and R600 will need a 600W PSU or higher with a six pin power connector for the GPU... wonder if I can get an adapter.

I'm just hoping that the prices will fall for the 8800 series. 450 - 700 is rediculous!

can't they just give us a suped up x1900 or 7950 capable of directx 10?!

I really hate the fact that there are only two major GPU chipset designers out there...:|

Tell you what,

if you look at the R600 digitized pics (hosted on VR-Zone I think), it is very similar to the actual thing. The R600 is indeed heavy, I've seen the OEM version, which is more or less the exact same one as the digitized pic, with the exception that it has dual 6-pin instead of the 8-pin. The heatsink on the thing is all copper with 4 heatpipes, approx the length of the card, and looks vaguely like the 7900GTX heatsink, albeit without the fan in the middle. The blower fan blows from the end of the card to the outside of the case. If you put two Zalman 7000CU's together, I think you'll have a good idea of how much the thing weighs, lol maybe even more.

i run 4x with no performance change..
