GeForce GTX 460 (OEM) vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which features GPU clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 460 (OEM) should in theory be a bit superior to the Radeon R9 M385X overall. (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 (more or less 69%) faster with regards to 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is superior to the Radeon R9 M385X, 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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
