Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon HD 4870 1GB should in theory be a little bit superior to the GeForce GTX 460 (OEM) overall. (explain)

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

Texel Rate

The GeForce GTX 460 (OEM) is a lot (more or less 21%) faster with regards to texture filtering than the Radeon HD 4870 1GB. (explain)

GeForce GTX 460 (OEM) 36400 Mtexels/sec
Radeon HD 4870 1GB 30000 Mtexels/sec
Difference: 6400 (21%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 (OEM) is superior to the Radeon HD 4870 1GB, by a large margin. (explain)

GeForce GTX 460 (OEM) 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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the 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 most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
