NVIDIA GeForce GTX 650 Ti BOOST Review


Testing - Temps, Voltages, Acoustics, and Overclocking



Temps were okay with the reference cooling with a single blower fan, idling at 30°C and under load rising to 64°C but at relatively low fan speeds.  Under overclock, the temps stayed about the same but the fan kicked up a bit higher towards 50%, and it still wasn't noticeably loud, either.  Idle voltages were 0.8887V, and under load they increased to 1.032V for 99% TDP.


Being that these are essentially GTX 660s that aren't quite up to snuff, in a similar way the the GTX 560 Ti 448 core were down-binned GTX 570s, we didn't anticipate a huge overclocking margin here.  The stock base clock of 980 MHz and boost clock (automatic OC) of 1033 MHz match those of the GTX 660, but the GTX 650 Ti Boost has fewer CUDA Cores and Texture Units.  We did find a little wiggle room and were able to boost the boost clock by about 10%, but we ran into alot of instability in the memory and were only able to boost that about a percent.  We saw framerate increases of about 5%, not a bad little boost, but nothing mindblowing, either.
