AMD's R7xx series GPUs to support DisplayPort

AMD's R7xx series GPUs to support DisplayPort

AMD's roadmaps suggest that its high-end R7xx series GPUs will not support PCIe 2.0 and not feature UVD. Typo or fact? Hmmm.

AMD looks set to introduce graphics cards with the new DisplayPort interface as early as next year, according to roadmaps released by the company at this year’s Analyst’s Day event.

DisplayPort was approved by VESA in April this year and both Dell and Samsung have discussed LCDs using the new connection interface. However, in order to use these displays, you’ll need a graphics card with a DisplayPort connector.

This is where AMD’s next-generation R7xx-series graphics cards come into play, as the company discussed implementing the connection interface into its graphics cards next year.

Looking over the company’s roadmaps with a closer eye reveals some potentially interesting facts about the R7xx series of graphics processing units. Currently, AMD is planning to use a 55nm manufacturing process on both its performance, mainstream and mobile GPUs – this should hopefully resolve the high power consumption problems AMD’s Radeon HD 2900 XT has suffered from.

Potentially more controversially though is the fact that, like the current situation, the company’s Unified Video Decoder doesn’t look like it’s going to be a feature on the more performance-orientated SKUs. Additionally, the second generation PCI-Express interface isn’t listed on the performance roadmap, but is on the mainstream roadmap – could it be that AMD’s next-generation high-end GPUs will not use the new bus technology?

The reasons, I guess are the fact that the high-end GPUs use a pair of internal CrossFire bridges for inter-GPU communications in multi-GPU mode. On the other hand, the more mainstream-orientated GPUs will pass all data over the PCI-Express bus, thus explaining the need for more bandwidth. Of course, the increased bandwidth isn’t the only new feature in PCIe 2.0, as there are the increased power figures too.

Some of this looks strange, and I guess we won't know the real answers until sometime next year when we have the hardware in hand. Do you think some of AMD's plans are strange? Share your thoughts in the forums.

Maybe your right Tim about the inter-GPU communication bridge(s) for the GPUs being the reason for no PCI-E 2.0, which could potentially help cut cost and draw less power? Idk really, but I think your hypothesis is probably right, but is it too late for them to include PCI-E 2.0 because I thought it would be the next standard? Also, do you think this choice will hampen performance? or will the proprietary bridge connector perform just as good? Also, I think the 55nm GPU (OC will probably be pretty good) would probably be a good sacrafice to PCI-E 2.0.......also what does Dispaly Port offer over HDMI 1.3 or even DVI?

i am ok with this as long as they don't pull another X2900.....

next year when we have hte hardware in hand.

*sits on hands waiting for some juicy hardware to play Crisis on*

I can agree on the adaptation of DisplayPort. PCIe 2.0, not so much. AFAIK, there aren't any breakthroughs in PCIe 2.0 that would help high-end cards to achieve comparable performance to if they just drew more power from external connections. Bandwidth-wise, we still haven't broken the AGP 8x interface's bandwidth limitation to the system bus, so there shouldn't be any substantiated gain over the first PCIe either.

DXR, the card to me was great for the price over here in the USA and also there was no good comparison to the 8800 because every game that was benchmarked was DX9 based and the 2900 is meant for DX10, and more heavily focused on shaders; which again there wasn't a good game to compare it on and there still isn't until a completely DX10-based game like Crysis debuts.....but I must agree that the specs, the price and the concluding benchmarks did/do make it seem mediocre especially outside of the US in terms of I hear you...but it really is a great card deep down....

good day for amd i just hope that something appears before my b'day in november

So it looks like they only plan a refresh of the 2900 and a (by the sounds of it) low end "2000" part for 2007? shame :( for us consumers the market on the whole desperately needs real competition to Nvida, otherwise prices will remain well above the previous norms and Nvidia won't feel pressure to bring anything new to the table either.
