GeForce GTX 460 vs Radeon R9 M385X

Intro

The GeForce GTX 460 uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this particular card. It features 336 SPUs as well as 56 TAUs and 24 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M385X, which has core clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X will be 11% faster than the GeForce GTX 460 overall, because of its higher bandwidth. (explain)

Radeon R9 M385X 96000 MB/sec
GeForce GTX 460 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The Radeon R9 M385X is quite a bit (more or less 63%) better at AF than the GeForce GTX 460. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 460 37800 Mtexels/sec
Difference: 23800 (63%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M385X is the winner, but only just. (explain)

Radeon R9 M385X 17600 Mpixels/sec
GeForce GTX 460 16200 Mpixels/sec
Difference: 1400 (9%)

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 largest amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
