GeForce GTX 560 Ti vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GTX 560 Ti comes with a GPU core clock speed of 822 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1002 MHz through a 256-bit bus. It also features 384 SPUs, 64 Texture Address Units, and 32 ROPs.

Compare those specs to the GeForce GTX 650 Ti 2GB, which features GPU core speed of 928 MHz, and 2048 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is made up of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB 110 Watts
GeForce GTX 560 Ti 170 Watts
Difference: 60 Watts (55%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti should be 48% faster than the GeForce GTX 650 Ti 2GB in general, due to its greater data rate. (explain)

GeForce GTX 560 Ti 128256 MB/sec
GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 41856 (48%)

Texel Rate

The GeForce GTX 650 Ti 2GB is a bit (more or less 13%) more effective at texture filtering than the GeForce GTX 560 Ti. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
GeForce GTX 560 Ti 52608 Mtexels/sec
Difference: 6784 (13%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Difference: 11456 (77%)

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 data (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
