GeForce GTS 450 vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which features a clock frequency of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 M260X should perform just a bit faster than the GeForce GTS 450 in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GTS 450		57728 MB/sec
	Difference: 6272 (11%)

Texel Rate

The GeForce GTS 450 should be a lot (more or less 27%) better at AF than the Radeon R7 M260X. (explain)

GeForce GTS 450		25056 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 5256 (27%)

Pixel Rate

The GeForce GTS 450 should be a lot (more or less 90%) faster with regards to AA than the Radeon R7 M260X, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTS 450		12528 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 5928 (90%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
