There looks to be two versions, the GTX660 OEM is a GK104 chip, whereas the retail version runs on the GK106 chip, albeit with less shaders (perhaps the GK106 is efficient enough to not feel the cut in the amount of shaders? Not sure).
GTX660 mini review Mini review. Wow, the 660 is a tiny card, in comparison to previous generations. As you can see from the pics below, against a 560Ti448 it's significantly shorter. One PCI-E power socket, two cooling fans, a single sli connector (no 3 way sli with this card folks). One thing to note, I had 301.42 WHQL drivers installed which I thought would carry across okay. They don't. I even tried the newer 306.02 WHQL drivers and they wouldn't recognise the card either. I had to use the included cd which had version 305.27 drivers. On with the benches! I picked a few that I had readily available, namely the CPC Benchmark 2007, just to see if the change made any impact on the system. Then I ran 3dmark2011. Once that had finished, I ran the Unigine 2.1 benchmark and lastly I ran the benchmark in Dirt Showdown. I'll tell you know, it's not all that impressive. I suppose it makes for a leaner, greener rig. I'm itching to see how this card overclocks though Here's a copy of the benchmark results in full: Custom PC Benchmarks Suite GTX560Ti448 Image editing: 1882 points. Video encoding: 3384 points.

Pics showing comparison to 560Ti448. Nowhere near conclusive results. I'd presume some games would take better advantage of the newer silicon. Perhaps it's down to drivers. Also, by jiminy it runs quiet! The fans of the 560 were certainly discernable. I couldn't hear the 660 fans revving up at all while benching. That's quite a major achievement in my book as for too long now I've had cards that have been quite loud at times.
I would think a fairer comparison would be a 660 to a 560. The Ti 448 is relatively high-end compared to a vanilla 560. That would show better what a generation jump does Not bad results though even if not as good as you had hoped.
Oh Ya. I 560 448 is basically a 570 yes? Which is two steps up from the 560. But on the plus point, it is quite near the performance of a card that was 2 jumps in performance away from its predecessor. Which ain't to be sniffed at. This is in the public domain now then this card?
The 560Ti448 isn't quite a 570 - it's not far off though and tbh with a little overclocking it does match a 570. Unfortunately, it's the only card I've got available Tweaktown have had a review up for a few days. Looking at the results though, the 660 is either a little slower, matches and sometimes bests a GTX580! Unfortunately, they haven't posted their test rig as the 3dmark score is quite a bit higher than mine. edit: oc results so far.. 3dm11 SCORE P6832 3DMarks GRAPHICS SCORE 6746 PHYSICS SCORE 8069 COMBINED SCORE 6029 Using MSI Afterburner settings of Power % 105 Core +110 Memory +535 GPU-Z reports GPU Clock 1080 Mhz (up from 980 Mhz) Memory 1770 (up from 1502 Mhz) Boost 1133 Mhz (up from 1033 Mhz) Bandwidth has gone up from 144 GB/s to 170GB/s.

Kenco, do you know when this card will hit the shelves and how much for? Is it looking like the replacement for the 560 Ti? My friend is going to be building a new PC very soon but his budget can only stretch to a 560 Ti rather than the 660 Ti and I'm wondering if its worth him holding off till this card gets launched.
It was £197 something pence. There were only 10 available at the time. I'd seen the tweaktown review and thought it looked alright. I can't seem to match their results though, even overclocked so I wonder if they reviewed the OEM version that has the extra sharers. Bit fishy methinks.
