Info on R580,G71 and ATi chipset

Post by Tiger Ace »

Collecting up three Inq articles that look fairly accurate(and agree with other sources that I don't have links to :? )

First off, R580.
The Inq wrote:We are still not sure about those numbers but our colleagues are reporting that top card named X1800XTX works at 695MHz core and 1550MHz memory. X1900XT will be clocked at 625MHz core and 1450MHz memory, no surprises there. There will be a Crossfire version of the card as well and samples are out there and ATI is hoping for a late January 2006 launch if not even early February.

The site claims that you need 450W with 30A for a single card while you need a minimum of 550W PSU providing 38A for two cards.

If this is accurate, it can lay waste to an GTX 'ultra'. Intresting, but won't it bottleneck with only 16 pipelines to display(even with 48 shaders)?

Next is G71.
The Inq wrote:
As the G71 will be able to process 32 pixels per clock, it will physically have 32 pipelines but will have just 16 ROPs. This is no surprise to us as Nvidia's G70, Geforce 7800 GTX actually has 24 pipelines and 16 ROPs.

This means that Nvidia and ATI will take completely new approaches, where Nvidia will try to convince everyone that you need more raw pixels than pixel operations.

The G70, Geforce 7800 GTX has 24 texture memory units and 16 ROPs and can theoretically draw eight pixels with each, having three textures per clock. G71 will be able to do even more pixels per clock - it's as simple as that.

ATI's R580, on the other hand, will still be able to push sixteen raw pixels per clock but will be able to render 48 pixel operations per clock. So ATI will insist on more per pixels operations before you actually draw the pixel. This kind of makes sense when you need more maps and calculations per pixels.
Looks good, as allways.


And the most intresting, a very capable intergrated graphics chip.
The Inq wrote: WE HEARD that ATI is working hard on a new integrated graphic core. This time it aims to have four pixel pipelines inside its chipset. Both Nvidia and ATI have only two pixel pipelines.
C51 and Radeon Xpress 200 chipsets both have two pixel pipelines powered with Hypermemory or turbo cache marchitecture. They can run some games at 800x600 and they can let you see some of the games before you go out and buy a decent graphic card.

The next generation of chipsets will feature a new integrated core with four pixel pipelines and it should be relatively close to the X600 performance. It might end up a little bit slower due to slower memory performance from the integrated memory, but it should be in that range.

This new graphic core enslaved in ATI's future chipset should feature all you need for Longhorn, Vista operating system. Yes, it's pixel Shader 2.0+ capable as well. µ


So we're back to actully usful IG graphics, cool.

So these integrated chips support dx9 and such?
