GeForce GTX 465 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 465 should theoretically perform a lot faster than the Radeon R7 M260X overall. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 38592 (60%)

Texel Rate

The GeForce GTX 465 will be a lot (more or less 35%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 6908 (35%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 465 is superior to the Radeon R7 M260X, by a large margin. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 12824 (194%)

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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
