GeForce GTX 465 vs Radeon RX 570

Intro

Compare all of that to the Radeon RX 570, which features a clock frequency of 1168 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 256-bit memory bus, and uses a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 465		26708 Mtexels/sec
	Difference: 122796 (460%)

Pixel Rate

The Radeon RX 570 should be a lot (more or less 92%) better at anti-aliasing than the GeForce GTX 465, and also should be capable of handling higher resolutions better. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 17952 (92%)

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 moved past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
