GeForce GTX 460 SE vs Radeon HD 5850

Intro

The GeForce GTX 460 SE makes use of a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 memory works at a speed of 850 MHz on this particular card. It features 288 SPUs along with 48 Texture Address Units and 32 ROPs.

Compare all that to the Radeon HD 5850, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this model. It features 1440(288x5) SPUs as well as 72 TAUs and 32 ROPs.

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

Texel Rate

The Radeon HD 5850 will be much (approximately 67%) more effective at texture 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

If using a high resolution is important to you, then the Radeon HD 5850 is the winner, though only just barely. (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 information (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
