GeForce GTX 460 (OEM) vs Radeon R9 M385X

Intro

The GeForce GTX 460 (OEM) has a clock frequency of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific model. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Radeon R9 M385X 96000 MB/sec
Difference: 12800 (13%)

Texel Rate

The Radeon R9 M385X is quite a bit (about 69%) faster with regards to AF than the GeForce GTX 460 (OEM). (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 460 (OEM) 36400 Mtexels/sec
Difference: 25200 (69%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is the winner, though only just barely. (explain)

GeForce GTX 460 (OEM) 20800 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 3200 (18%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
