GeForce GTX 460 (OEM) vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this card. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) will be 13% quicker than the Radeon R9 M385X overall, due to its greater bandwidth. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 12800 (13%)

Texel Rate

The Radeon R9 M385X should be quite a bit (approximately 69%) faster with regards to anisotropic filtering 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 using a high resolution is important to you, then the GeForce GTX 460 (OEM) is the winner, not by a very large margin though. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
