GeForce GTX 650 Ti 2GB vs GeForce GTX 660
Intro
The GeForce GTX 650 Ti 2GB features a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare all of that to the GeForce GTX 660, which comes with a core clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 192-bit bus, and uses a 28 nm design. It is made up of 960 SPUs, 80 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.

6 Responses to “GeForce GTX 650 Ti 2GB vs GeForce GTX 660”what is the different between the two graphic cards? i dont know. and im going to buy the GTX 650 TI 2 GB and my friend got the other card. So i just wanna know what is best, and why?! 😀
The gtx-660 is better in general so i think there is no need for an thorough explaination.
why you havent gtx650 ti boost? its not too much weaker that gtx 660 and a littre cheaper for sure its better that 650 ti and can be used in sli
As of 12/23/ there are no 660ti's in the price range of the 760's. You can get a 660 FTW at newegg for $239.99 but the 760 is the same exact price.
nVidia is doing just like Intel and reaming us with prices. I got a gtx 260 in 2010 for $180 and despite all that time I have to shell out $200 for a faster card. Any card like the GTX 650 that is less than $200 is SLOWER than the card I bought 4 years ago.
And it doesn't matter.... 660ti... 760... you aren't really going to find a "deal" on any of them. You'd think after a new line of cards they would go down in price!!!!!
DO NOT buy the 650 get the 660 or 760 is my point really. The 650 (Or ANY card under $180) will be SLOWER than the previous generations of cards (ie 260 460, etc)
Bend over and let your wallet get fucked.
You;d think after all this time I could get a card that outperforms the 260 for less than $150.....
Would you please add the GTX 650 TI Boost?
