GeForce GTS 450 vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which features a GPU core clock speed of 925 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should in theory be a lot superior to the GeForce GTS 450 overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GTS 450		57728 MB/sec
	Difference: 14272 (25%)

Texel Rate

The Radeon R9 M365X is much (more or less 48%) faster with regards to texture filtering than the GeForce GTS 450. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 11944 (48%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M365X is a better choice, though only just barely. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GTS 450		12528 Mpixels/sec
	Difference: 2272 (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at 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 graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
