GeForce GTX 465 vs Radeon R7 240

Intro

Compare those specs to the Radeon R7 240, which features a clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

As far as performance goes, the GeForce GTX 465 should in theory be a lot superior to the Radeon R7 240 overall. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 73792 (256%)

Texel Rate

The GeForce GTX 465 should be much (approximately 83%) better at AF than the Radeon R7 240. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 12108 (83%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 465 is the winner, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 13584 (233%)

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 information (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
