GeForce GTX 465 vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which comes with GPU core speed of 926 MHz, and 8192 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

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

Memory Bandwidth

In theory, the Radeon RX 470 will be 106% faster than the GeForce GTX 465 in general, because of its higher data rate. (explain)

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

Texel Rate

The Radeon RX 470 will be quite a bit (approximately 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 a high resolution is important to you, then the Radeon RX 470 is the winner, 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
