GeForce GTX 560 Ti vs Radeon HD 7850

Intro

The GeForce GTX 560 Ti comes with clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.

Compare all of that to the Radeon HD 7850, which features a core clock speed of 860 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7850 130 Watts
GeForce GTX 560 Ti 170 Watts
Difference: 40 Watts (31%)

Memory Bandwidth

In theory, the Radeon HD 7850 should be 20% faster than the GeForce GTX 560 Ti in general, because of its greater bandwidth. (explain)

Radeon HD 7850 153600 MB/sec
GeForce GTX 560 Ti 128256 MB/sec
Difference: 25344 (20%)

Texel Rate

The Radeon HD 7850 should be just a bit (approximately 5%) faster with regards to anisotropic filtering than the GeForce GTX 560 Ti. (explain)

Radeon HD 7850 55040 Mtexels/sec
GeForce GTX 560 Ti 52608 Mtexels/sec
Difference: 2432 (5%)

Pixel Rate

The Radeon HD 7850 will be a bit (approximately 5%) faster with regards to AA than the GeForce GTX 560 Ti, and will be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 7850 27520 Mpixels/sec
GeForce GTX 560 Ti 26304 Mpixels/sec
Difference: 1216 (5%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a 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 - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
