GeForce GTX 460 vs Radeon R9 M385X

Intro

The GeForce GTX 460 features a core clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also features a 192-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.

Compare those specs to the Radeon R9 M385X, which features GPU clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should perform a small bit faster than the GeForce GTX 460 overall. (explain)

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

Texel Rate

The Radeon R9 M385X will be 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 little bit (about 9%) more effective at anti-aliasing than the GeForce GTX 460, and also able to handle higher resolutions more effectively. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics 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 amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
