GeForce GTX 465 vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which has clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Radeon RX 470		120 Watts
GeForce GTX 465		200 Watts
	Difference: 80 Watts (67%)

Memory Bandwidth

The Radeon RX 470, in theory, should be quite a bit faster than the GeForce GTX 465 in general. (explain)

Radeon RX 470		211200 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 108608 (106%)

Texel Rate

The Radeon RX 470 should be a lot (more or less 344%) better at texture filtering than the GeForce GTX 465. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 91820 (344%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 470 is superior to the GeForce GTX 465, by far. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 10208 (53%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
