GeForce GTX 460 SE vs Radeon HD 4870 1GB

Intro

The GeForce GTX 460 SE features core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Compare all that to the Radeon HD 4870 1GB, which comes with clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon HD 4870 1GB should perform a bit faster than the GeForce GTX 460 SE in general. (explain)

Radeon HD 4870 1GB 115200 MB/sec
GeForce GTX 460 SE 108800 MB/sec
Difference: 6400 (6%)

Texel Rate

The GeForce GTX 460 SE will be just a bit (more or less 4%) faster with regards to texture filtering than the Radeon HD 4870 1GB. (explain)

GeForce GTX 460 SE 31200 Mtexels/sec
Radeon HD 4870 1GB 30000 Mtexels/sec
Difference: 1200 (4%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 4870 1GB, by a large margin. (explain)

GeForce GTX 460 SE 20800 Mpixels/sec
Radeon HD 4870 1GB 12000 Mpixels/sec
Difference: 8800 (73%)

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 largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
