GeForce GTX 460 vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which features a core clock frequency of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should theoretically perform a 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 quite a bit (approximately 63%) more effective at anisotropic filtering than the GeForce GTX 460. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 23800 (63%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M385X is superior to the GeForce GTX 460, though not by far. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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