GeForce GTX 460 2GB vs Radeon R9 M385X

Intro

The GeForce GTX 460 2GB features core clock speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon R9 M385X, which features a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 2GB should perform just a bit faster than the Radeon R9 M385X in general. (explain)

GeForce GTX 460 2GB 115200 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 19200 (20%)

Texel Rate

The Radeon R9 M385X should be quite a bit (approximately 63%) more effective at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 23800 (63%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 2GB is a better choice, by a large margin. (explain)

GeForce GTX 460 2GB 21600 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 4000 (23%)

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 (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
