Complete Nvidia Kepler GPU Lineup Leaked
Unlike with the AMD Radeon HD 7000 series, the Nvidia has kept it very quiet with regards to information being leaked on its upcoming Kepler series graphics cards. Website Lenzfire has published specifications for the upcoming Kepler series. As with all leaked information, all unofficial sources should be taken with a grain of salt.
With the chart listed below, we see see the entire lineup of Kepler cards from the flagship Nvidia GTX 690 dual GPU to the GTX 640. The die size in the higher end GeForce cards are approximately 50 percent larger than that of the AMD Radeon HD 7970 (550mm2 vs 365mm2), while only 30mm2 larger than its GF110 predecessor (GTX 580).
| Model | Die Size (mm2) | Core Clock MHz (TBD) | Shader Clock GHZ (TBD) | Stream Processors | SM Count | ROPs | Memory Clock (effective) GDDR5 | Bus Width | Memory Bus Width (GB/s) |
|---|---|---|---|---|---|---|---|---|---|
| GTX690 (2xGK110) | 550 | ~750 | ~1.5 | 2x1024 | 2x32 | 2x56 | 4.5 GHz | 2x448bit | 2x252 |
| GTX680 (GK110) | 550 | ~850 | ~1.7 | 1024 | 32 | 64 | 5.5 GHz | 512bit | 352 |
| GTX670 (GK110) | 550 | ~850 | ~1.7 | 896 | 28 | 56 | 5 GHz | 448bit | 280 |
| GTX660 Ti (GTX110) | 550 | ~850 | ~1.7 | 768 | 24 | 48 | 5 GHz | 384bit | 240 |
| GTX660 (GK104) | 290 | ~900 | ~1.8 | 512 | 16 | 32 | 5.8 GHz | 256bit | 186 |
| GTX650 Ti (GK104) | 290 | ~850 | ~1.7 | 448 | 14 | 28 | 5.5 GHz | 224bit | 154 |
| GTX650 (GK106) | 155 | ~900 | ~1.8 | 256 | 8 | 24 | 5.5 GHz | 192bit | 132 |
| GTX640 (GK106) | 155 | ~850 | ~1.7 | 192 | 6 | 16 | 5.5 GHz | 128bit | 88 |
In the chart below, we get details on price points, release dates and expected performance scale compared to current Nvidia GPUs and AMD's HD 7000 series. Based on the performance numbers, the GTX 680 is set to show a 45 percent performance increase over the HD 7970, while the GTX 670 shows a 20 percent improvement. If the numbers are true, this would be a nice win for Nvidia's Kepler against AMD's new Graphics Core Next architecture. The GTX 660 Ti is set to show a 10 percent improvement over the HD 7950 in the current battle of price to performance ratio. Though we don't have estimated performance numbers for AMD's HD 78xx or 77xx series, Nvidia's budget-friendly cards stack up nicely to its current high-end graphics cards.
| Model | Bus Interface | Frame Buffer | Transistors (Billion) | Price Point | Release Date | Performance Scale |
|---|---|---|---|---|---|---|
| GTX690 | PCIe3.0x16 | 2x1.75GB | 2x6.4B | $999 | Q3 2012 | N/A |
| GTX680 | PCIe3.0x16 | 2GB | 6.4B | $649 | 12-Apr | 45% > HD7970 |
| GTX670 | PCIe3.0x16 | 1.75GB | 6.4B | $499 | 12-Apr | 20% > HD7970 |
| GTX660 TI | PCIe3.0x16 | 1.5GB | 6.4B | $399 | Q2/Q3 2012 | 10% > HD7950 |
| GTX660 | PCIe3.0x16 | 2GB | 3.4B | $319 | 12-Apr | = GTX580 |
| GTX650 TI | PCIe3.0x16 | 1.75GB | 3.4B | $249 | Q2/Q3 2012 | = GTX570 |
| GTX650 | PCIe3.0x16 | 1.5GB | 1.8B | $179 | 12-May | = GTX560 |
| GTX640 | PCIe3.0x16 | 2GB | 1.8B | $139 | 12-May | = GTX550Ti |
Do you think Nvidia's Kepler will live up to the alleged performance figures and regain the performance crown from AMD?
Edit: Charts corrected to show MHz for Core Clock
Ding ding ding, Fanboi alert..
I think not. I get that these are estimates, but I hope they are not accurate.

Yep, price fixing at its finest. I remember a year or two back some e-mails between AMD and Nvidia were leaked that showed evidence of them collaborating to fix/inflate GPU prices.
if kepler's power consumption is like fermi cards, imo amd will win. sales is another story (nvidia usually makes more money:()....

550mm2 and 6.4B transistors, that's pretty much but not that effective as ATI Graphics with even smaller die size a powerful chip than the last one.
AMD pulled quite a marketing scheme by releasing high end cards with extremely conservative clock/memory speeds, that has "High Overclock Potential 25-30%." It sells well to do it like this. You know, release a card with "great potential," then jack up the price so people think they got they're moneys worth. If they wanted they could have easily released these cards with that same overclock back in January.
Maybe by the time Nvidia releases it's 680, AMD will have done a lil bit of tweaking, and will release overclocked cards that will negate that 20-45% improvement, and bring it down to 0-20%. Oh, 7970 drivers should be optimized by then which will bring that performance down even more.
I'm not dissing AMD, well, maybe a lil bit.
