MSI GeForce GTX 670 Pictured Up Close
Here are the first pictures of MSI GeForce GTX 670. The GTX 670 will be NVIDIA's third SKU based on the GK104, and will be positioned to compete with AMD Radeon HD 7950. The card pictured below is nearly identical to a Leadtek-branded one that was pictured last week, which leads us to believe that this could very well be NVIDIA reference design, with just MSI's sticker on. One can deduce, by the location of the two 6-pin PCIe power connectors, that this card also uses a different PCB layout from the one GeForce GTX 680 does.
The source also mentions some specifications, some of which we know from older reports, some of which we don't. The card packs 1344 CUDA cores, 112 TMUs, 32 ROPs, a 256-bit wide GDDR5 memory interface holding 2 GB of memory, and clock-speeds of 900 MHz (core base), 1250 MHz actual or 5.00 GHz effective GDDR5 memory. It is predicted that future non-reference designs could come in much shorter PCBs thanks to rather slim VRM requirements, and just 8 memory chips, the GPU package isn't too big, either. Display outputs include two dual-link DVI, and one each of HDMI and DisplayPort. So the ability to set up 3D Vision Surround from one card could remain intact. Lastly, the box mentions "OC Edition", and so the card could come with out of the box overclocked speeds. There's also a juicy typo on that box.

Gah I looked but couldn't find the typo where is it? I suck at English.
also it looks like the pcb is wicked short. Hoping this hits at a $350-399 price range and is within 10-15% of the gtx680 this could be my card when the non-reference boards pour in
I do not think there is a specific reason for the location of power connectors maybe just some news to show or to give space for the fan.
7950 v 670
1792 @ 800mhz = 1344 + 224 @ 914mhz.
50% more bandwidth = ~8% more performance = 914x1.08 = 988mhz
expected boost clock: 1ghz
Expectation: They will perform very similar, except in scenarios limited by texture/rop/pixel fillrate unit clocks. Overclocked they will be similar all-around or advantage AMD as unlike 7970 vs 680, 7950 is not ROP-limited (or shader over-kill depending on how you look at it) and with similar clockspeeds the greater IPC will become apparent.
7870 v 660ti
1280 @ 1000mhz = 1152 + 192 @ 953mhz
28% more bandwidth = ~4.5% more performance = 953x1.045 = 996mhz
expected clocks: same as 670 (1ghz boost/5ghz mem)
Expectation: They will perform very similar. 660ti closer to what many expected Pitcairn to be than what it actually was, which really isn't all that different.
7850 vs 660
1024 @ 860mhz = 768 + 192 @ 983mhz
28% more bw = ~4.5% more perf = 983x1.045 = 1027mhz
expected clocks: 1.12 boost/5ghz mem
Expectation: Between edging out and putting the hurt on 7850 at default clocks depending on game bottleneck (similar to 670 vs 7950). Overclocked the story is murky. Depending on if people care enough to try to get 7850's above 1050mhz, which AMD has tried their hardest to stop, and/or find a card with voltage adjustments (which AMD also doesn't like hence the powertune cap) it could go from a tie to advantage AMD. The obvious response, of course, is this is when AMD shows the real value of Pitcairn and it edges closer to becoming the new Barts.
P.S. Just imagine: 2GB GDDR5 512-bit gfx card, beast isn't it? :) :toast:
Tiny card like Zotac 560 SE.
