GeForce GTX 560 Ti vs Radeon HD 5850

Intro

The GeForce GTX 560 Ti has clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 5850, which comes with a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 1440(288x5) SPUs, 72 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5850 151 Watts
GeForce GTX 560 Ti 170 Watts
Difference: 19 Watts (13%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 Ti should in theory be a bit better than the Radeon HD 5850 overall. (explain)

GeForce GTX 560 Ti 128256 MB/sec
Radeon HD 5850 128000 MB/sec
Difference: 256 (0%)

Texel Rate

The GeForce GTX 560 Ti should be just a bit (about 1%) more effective at texture filtering than the Radeon HD 5850. (explain)

GeForce GTX 560 Ti 52608 Mtexels/sec
Radeon HD 5850 52200 Mtexels/sec
Difference: 408 (1%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 Ti is a better choice, not by a very large margin though. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
Radeon HD 5850 23200 Mpixels/sec
Difference: 3104 (13%)

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 (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
