Benchmarks from Anand tech
In reply to Jim Cockfield, Jan 18, 2013

And these benchmarks are for the 660  not the 660 ti

Coming from the GTX 660 and its fully enabled GK106 GPU, NVIDIA has cut several features and functional units in order to bring the GTX 650 Ti down to their desired TDP and price. As is customary for lower tier parts, GTX 650 Ti ships with a binned GK106 GPU with some functional units disabled, where it unfortunately takes a big hit. For the GTX 650 Ti NVIDIA has opted to disable both SMXes and ROP/L2/memory clusters, with a greater emphasis on the latter.

On the shader side of the equation NVIDIA is disabling just a single SMX, giving GTX 650 Ti 768 CUDA cores and 64 texture units. On the ROP/L2/memory side of things however NVIDIA is disabling one of GK106’s three clusters (the minimum granularity for such a change), so coming from the GTX 660 the GTX 650 Ti will have much less memory bandwith and ROP throughput than its older sibling.

Taking a look at clockspeeds, along with the reduction in functional units there has also been a reduction in clockspeeds across the board. The GTX 650 Ti will ship at 925MHz, 65MHz lower than the GTX 660 Ti. Furthermore NVIDIA has decided to limit GPU boost functionality to the GTX 660 and higher families, so the GTX 650 Ti will actually run at 925MHz and no higher. The lack of a boost clock means the effective difference is closer to 100MHz. On the other hand the lack of min-maxing here by NVIDIA will have some good ramifications for overclocking, as we’ll see. Meanwhile the memory clock will be at 5.4GHz, which at only 600MHz below NVIDIA’s standards-bearer Kepler memory clock of 6GHz is not nearly as big as the loss of memory bandwidth from the memory bus width reduction.

Overall this gives the GTX 650 Ti approximately 72% of the shading/texturing performance, 60% of the ROP throughput, and 60% of the memory bandwidth of the GTX 660. Meanwhile compared to the GTX 650 the GTX 650 Ti has 175% of shading/texturing performance, 108% of the memory bandwidth, and 87% of the ROP throughput of its smaller predecessor. For what little tradition there is, NVIDIA’s x50 parts are traditionally geared towards 1680x1050/1600x900 resolutions. And while NVIDIA is trying to stretch that definition due to the popularity of 1920x1080 monitors, the loss of the ROP/memory cluster all but closes the door on the GTX 650 Ti’s 1080p ambitions. The GTX 650 Ti will be for all intents and purposes NVIDIA’s fastest sub-1080p Kepler card.
