This is a great article. A recommended read!
ATI Radeon 4800 launch details: Meet (Terry) Makedon and Trojan (Horse)

The Radeon 4800 series also includes 7.1 channel-via-HDMI support and color output also got a �significant� boost, our sources said. We were unable to confirm HDMI 1.3 support, but we would not be surprised if that in fact is the case. The Unified Video Decoder is now in generation 2 and is called "UVD2".

Hey Supreet Virdi & SombaSan it's been awile guys.

Does anybody know if you can pair up a HD 3870 with a HD 4870 in CrossfireX?
ATI's website is not clear about this but several are saying YES you can because its based on the new Spider Platform and its CrossFire "X"

I highly doubt that will be implemented... it would be a load balancing nightmare from a software standpoint to try and get two very un-evenly matched video cards to try and sync up frame for frame.

Greetings everyone, I'm back! I'll be spend the next week catching up on the last 3 months of hardware updates.

Regards,

That's Intel's business and 16 PCI Express lanes is plenty to cover it. 32 lanes is simply ridiculous for today's consumer products.

I agree new graphic cards should be at least 2 x faster, companies should also come out with better supporting mobo chipsets to further maximize video card performance.

This should be "in the theoretical world" vs "real world". Just because the chip throughput may be higher, it does not indicate that once implemented you'll get a big jump.
When the 386DX-16 came out it outran just about anything in the PC market by at least a factor of 4x, but the associated physical and logical infrastructure did not permit it.
It should be, not how much faster it can do a single thing, but how much faster it can do multiple things, or at least how many more things it can do at the same speeds.

I hope its not that slow... ATI or nVidia need to release something that is at least 2x faster per chip than G80.

Maybe a bit more

We've learned that ATI's new chip might end up 1.5 to 1.6 times faster than the current RV670 solution.

In the real world, this should mean that if one game gives 50FPS with RV670 that the new chip should be able to get you around 75FPS at the same settings. On average, the new chip will have to be at least 30 percent faster than the old one to make you even consider it, but at least specification-wise there is not anything that you might miss.

RV670 was a shrunk and a better speced version of R600 with 512bit memory controller crippled to 256-bit; and it looks that R770 will get that memory upped to 512-bit again. At least we know it will end up being fast, but we still don�t know what Nvidia�s real answer is to this one.

I am glad AMD/ATI is putting the pressure on NVIDIA.
