[WCCF]More AMD HD7900 GCN (Southern Island) Details Leaked: Frequencies, Prices and Release dates

Recent announcements and presentations from AMD suggest that the much anticipated 28nm Radeon HD7900 Series Graphic Cards will be launching in Q1 2012 (Jaunuary 2012). Other than the release dates, Technical specs which include frequencies and Next Gen GNC Core Architecture details have also been leaked.



GCN HD7970 (XT Tahiti):

The HD7970 is based on the 28nm Tahiti XT core and would be the fastest single chip GPU of the 7000 Series. It features a massive 2048 Cores (Shader Processors) or 32 CU (Compute Units),128 texture units and the core frequency is maintained at 1Ghz. One bad news is that AMD has ruled out the use of Rambus XDR2 memory and is reusing the 1.37 GHz GDDR5 quad data rate, ie at 5.5 GHz of bits used by these GDDR5 384-bit will result in 3 GB of RAM.

This means that the HD7970 would feature a record memory bandwidth of 264 GB / s against 174GB / s of HD6970. Pricing of the card would be set at $449 US.

HD7990 and HD7950 Details at source. thumb.gif

The 7900 series by Nvidia featured the most powerful graphics cards of their time, but it was released in... what... 2006.

But anyway, it's nice to know that AMD is finally catching up with the 7900 series.

That article claims that Kepler is going to be twice as fast as Fermi. I'd be quite surprised if they pulled off that kind of increase.

The 7970 will be my first high end non mid range card. I can't wait. It looks very promising. Should be able to run anything at 1200p.

Supposed prices are much higher than AMD's lineup the last few years. Curious to see if the performance increase is enough to maintain AMD high price/performance ratio.

Also, if rumors are correct, looks like AMD will have pretty much the entire market to themselves again for at least 6 month, a la HD5000 series.
