GeForce GTX 460 SE vs Radeon HD 5850

Intro

The GeForce GTX 460 SE has a GPU core clock speed of 650 MHz, and the 1024 MB of GDDR5 RAM runs at 850 MHz through a 256-bit bus. It also is comprised of 288 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

Compare those specs to the Radeon HD 5850, which features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs along with 72 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 SE 150 Watts
Radeon HD 5850 151 Watts
Difference: 1 Watts (1%)

Memory Bandwidth

The Radeon HD 5850, in theory, should be just a bit faster than the GeForce GTX 460 SE overall. (explain)

Radeon HD 5850 128000 MB/sec
GeForce GTX 460 SE 108800 MB/sec
Difference: 19200 (18%)

Texel Rate

The Radeon HD 5850 is a lot (more or less 67%) more effective at AF than the GeForce GTX 460 SE. (explain)

Radeon HD 5850 52200 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 21000 (67%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5850 is a better choice, but it probably won't make a huge difference. (explain)

Radeon HD 5850 23200 Mpixels/sec
GeForce GTX 460 SE 20800 Mpixels/sec
Difference: 2400 (12%)

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 (in units of MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
