GeForce GTX 560 Ti vs Radeon HD 7850

Intro

The GeForce GTX 560 Ti comes with a GPU core speed of 822 MHz, and the 1024 MB of GDDR5 memory runs at 1002 MHz through a 256-bit bus. It also is comprised of 384 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Compare that to the Radeon HD 7850, which comes with core speeds of 860 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

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 perform a little bit faster than the GeForce GTX 560 Ti in general. (explain)

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

Texel Rate

The Radeon HD 7850 will be a little bit (about 5%) better at 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

If using high levels of AA is important to you, then the Radeon HD 7850 is the winner, but not by far. (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 (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
