GeForce GTX 460 SE vs Radeon HD 5850

Intro

The GeForce GTX 460 SE comes with a GPU core clock speed of 650 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 256-bit bus. It also is comprised of 288 SPUs, 48 TAUs, and 32 ROPs.

Compare those specs to the Radeon HD 5850, which features core 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.

GeForce GTX 460 SE 108800 MB/sec
Difference: 19200 (18%)

Texel Rate

The Radeon HD 5850 should be quite a bit (about 67%) faster with regards to anisotropic filtering 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

The Radeon HD 5850 should be a little bit (approximately 12%) faster with regards to full screen anti-aliasing than the GeForce GTX 460 SE, and should be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
