GeForce GTX 460 2GB vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular model. 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 2GB is 20% faster than the Radeon R9 M385X in general, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R9 M385X will be quite a bit (approximately 63%) better at texture 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

The GeForce GTX 460 2GB should be quite a bit (about 23%) better at FSAA than the Radeon R9 M385X, and also will be able to handle higher screen resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
