Nvidia GeForce GTX 650 Ti: Tech Specs
Like the higher-end GTX 660, the GeForce GTX 650 Ti uses a GK106 GPU. However, everything has been scaled down in this model. The CUDA cores have been cut from 960 to 768 and the GPU clock speed has been reduced from 980 MHz to 925 MHz. The GPU also loses the GPU Boost function so the clock speed stays the same in games.
There's only 1 GB of GDDR5 memory here, with a 128-bit bus rather than the 192-bit bus used in the GTX 660. The memory clock has also dropped from 1502 to 1350 MHz.
The GeForce GTX 650 Ti reference card is very compact, with a PCB that's barely 14.5 cm long. The cooling system is also small, which could have you fearing the worst. But—fear not—in practice, it's really quite discreet!
Whether at idle or when gaming, noise output remains quite low with this graphics card. It's no match for the likes of the Asus GTX 660 Ti TOP DCU II but, for once, we wouldn't advise against buying models that use the same cooling system as the reference card.
It's no surprise to see that power use is well controlled in this graphics card. At idle, our test computer was only using 47 watts, rising to barely 141 watts in games! These results place the GTX 650 Ti between the AMD Radeon HD 7770 and Radeon HD 7850.
PERFORMANCE IN GAMES
In its marketing docs, Nvidia places the 650 Ti on par with the Radeon HD 7770. However, the Nvidia model clearly outdid the AMD Radeon in our tests, with the GeForce proving 24% faster on average. However, AMD's Radeon HD 7850 1 GB card sells for a similar price to the GTX 650 Ti and is 22% faster. And, the GeForce GTX 650 Ti is still 34% slower than a GTX 660.

In the end, this compact Nvidia graphics card handily fills a void in AMD's product range, nestling neatly between the Radeon HD 7770 and the Radeon HD 7850 1 GB. As usual, it'll be worth keeping an eye on the price of all these models to make sure your getting the best performances for your money.
