GeForce GTX 460 (OEM) vs Radeon R9 M265X

Intro

The GeForce GTX 460 (OEM) uses a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 memory runs at a speed of 850 MHz on this specific card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Compare that to the Radeon R9 M265X, which comes with core clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 (OEM) should in theory perform quite a bit faster than the Radeon R9 M265X in general. (explain)

GeForce GTX 460 (OEM) 108800 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 36800 (51%)

Texel Rate

The GeForce GTX 460 (OEM) should be a lot (approximately 58%) better at texture filtering than the Radeon R9 M265X. (explain)

GeForce GTX 460 (OEM) 36400 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 13400 (58%)

Pixel Rate

The GeForce GTX 460 (OEM) will be quite a bit (more or less 126%) more effective at FSAA than the Radeon R9 M265X, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 460 (OEM) 20800 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 11600 (126%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
