Although there were quite a few rumors leading up to AMD’s Radeon 7000 series launch, the Internet has been very quiet on the greener side of the graphics market. Finally; however, we have some rumors to share with you on the Nvidia front. As always, take these numbers with more than your average grain of salt.
Specifically, EXP Review managed to uncover two charts that supposedly detail specifics about a range of GeForce 600 series Kepler cards from the number of stream processors to the release date. Needless to say, it’s a lot of rumored information to take in all at once.
Anyway, without further adieu, let’s dive into the two leaked charts.
|Model||Code Name||Die Size||Core Clock (TBD) MHz||Shader Clock (TBD) GHz||Stream Processors||SM Count||ROPs||Memory Clock (effective) GDDR5||Bus Width||Memory Bus Width|
From the chart above, we can see the entire lineup of Kepler cards from the NVIDIA GTX 640 to the dual GPU GTX 690. The die size in the higher end GeForce cards is approximately 50% larger than that of the AMD Radeon HD 7970, but not much bigger than that of the GTX 580. If only we knew the TDP of these cards! In the next chart, we see alleged performance comparison versus the AMD competition.
|Model||Bus Interface||Frame Buffer||Transistors (Billion)||Price Point||Release Date||Performance Scale|
|GTX690||PCI-E 3 x16||2×1.75 GB||2×6.4||$999||Q3 2012|
|GTX680||PCI-E 3 x16||2 GB||6.4||$649||April 2012||~45%>HD7970|
|GTX670||PCI-E 3 x16||1.75 GB||6.4||$499||April 2012||~20%>HD7970|
|GTX660Ti||PCI-E 3 x16||1.5 GB||6.4||$399||Q2/Q3 2012||~10%>HD7950|
|GTX660||PCI-E 3 x16||2 GB||3.4||$319||April 2012||~GTX580|
|GTX650Ti||PCI-E 3 x16||1.75 GB||3.4||$249||Q2/Q3 2012||~GTX570|
|GTX650||PCI-E 3 x16||1.5 GB||1.8||$179||May 2012||~GTX560|
|GTX640||PCI-E 3 x16||2 GB||1.8||$139||May 2012||~GTX550Ti|
If these numbers hold true, NVIDIA will handily beat the current AMD offerings; however, I would wait for reviews to come out before making any purchasing decisions. One interesting aspect is the amount of GDDR5 memory. It seems that NVIDIA is sticking with 2GB frame buffers (or less) per GPU while AMD has really started upping the RAM. It will be interesting to see how this affects gaming in NVIDIA Surround and/or at high resolutions.
What do you guys think about these numbers, do you think Kepler will live up to the alleged performance scale figures?
