GeForce GTX 470 vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 470 should in theory perform much faster than the Radeon R9 M375X in general. (explain)

GeForce GTX 470		133920 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 61920 (86%)

Texel Rate

The Radeon R9 M375X is a small bit (more or less 19%) more effective at anisotropic filtering than the GeForce GTX 470. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 6608 (19%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 470 is the winner, by far. (explain)

GeForce GTX 470		24280 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 8040 (50%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
