GeForce GTX 460 (OEM) vs Radeon R9 M385X

Intro

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 is set to run at a speed of 1500 MHz on this particular card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) should 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 is much (approximately 69%) more effective at texture 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

The GeForce GTX 460 (OEM) is just a bit (approximately 18%) more effective at FSAA than the Radeon R9 M385X, and capable of handling higher resolutions better. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 number of pixels the video card can possibly record to its 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 - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 max fill rate.
