GeForce GTX 460 vs Radeon R9 M385X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M385X should theoretically be a small bit better than the GeForce GTX 460 in general. (explain)

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

Texel Rate

The Radeon R9 M385X is much (more or less 63%) more effective 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

The Radeon R9 M385X should be a small bit (about 9%) better at FSAA than the GeForce GTX 460, and also able to handle higher screen resolutions without slowing down too much. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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