GeForce GTX 465 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which comes with a clock speed of 715 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 465 should perform much faster than the Radeon R7 M260 overall. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 86592 (541%)

Texel Rate

The GeForce GTX 465 should be a lot (about 56%) faster with regards to AF than the Radeon R7 M260. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 9548 (56%)

Pixel Rate

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

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 13704 (240%)

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 (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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