GeForce GTX 650 vs GeForce GTX 660

Intro

The GeForce GTX 650 has core clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

Compare that to the GeForce GTX 660, which uses a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this card. It features 960 SPUs as well as 80 TAUs and 24 ROPs.

Power Consumption (Max TDP)

GeForce GTX 650 64 Watts
GeForce GTX 660 140 Watts
Difference: 76 Watts (119%)

Memory Bandwidth

The GeForce GTX 660 should theoretically perform a lot faster than the GeForce GTX 650 overall. (explain)

GeForce GTX 660 144192 MB/sec
GeForce GTX 650 80000 MB/sec
Difference: 64192 (80%)

Texel Rate

The GeForce GTX 660 is quite a bit (approximately 132%) better at anisotropic filtering than the GeForce GTX 650. (explain)

GeForce GTX 660 78400 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 44544 (132%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 660 is a better choice, and very much so. (explain)

GeForce GTX 660 23520 Mpixels/sec
GeForce GTX 650 16928 Mpixels/sec
Difference: 6592 (39%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

Take it from someone who upgraded from a 9800gt to a GTX650 to a GTX660. The first upgrade was a slight improvement (rather disappointing in fact). But the jump from the 650 to the 660 was huge! Hello 1080 gaming!
