GeForce GTS 450 vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which comes with core speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X, in theory, should be much faster than the GeForce GTS 450 overall. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GTS 450		57728 MB/sec
	Difference: 14272 (25%)

Texel Rate

The Radeon R9 M370X is much (approximately 28%) faster with regards to texture filtering than the GeForce GTS 450. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 6944 (28%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M370X is the winner, not by a very large margin though. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GTS 450		12528 Mpixels/sec
	Difference: 272 (2%)

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 (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
