VS

GeForce GTX 570 vs GeForce GTX 650 Ti

Intro

The GeForce GTX 570 features a GPU core speed of 732 MHz, and the 1280 MB of GDDR5 memory is set to run at 950 MHz through a 320-bit bus. It also is made up of 480 SPUs, 60 TAUs, and 40 Raster Operation Units.

Compare those specs to the GeForce GTX 650 Ti, which comes with a clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 110 Watts
GeForce GTX 570 219 Watts
Difference: 109 Watts (99%)

Memory Bandwidth

In theory, the GeForce GTX 570 should be 76% quicker than the GeForce GTX 650 Ti overall, due to its higher bandwidth. (explain)

GeForce GTX 570 152000 MB/sec
GeForce GTX 650 Ti 86400 MB/sec
Difference: 65600 (76%)

Texel Rate

The GeForce GTX 650 Ti should be a lot (more or less 35%) more effective at texture filtering than the GeForce GTX 570. (explain)

GeForce GTX 650 Ti 59392 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 15472 (35%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is a better choice, and very much so. (explain)

GeForce GTX 570 29280 Mpixels/sec
GeForce GTX 650 Ti 14848 Mpixels/sec
Difference: 14432 (97%)

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: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
