GeForce GTX 280 vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which uses a 14 nm design. AMD has clocked the core frequency at 1168 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

GeForce GTX 280		48160 Mtexels/sec
	Difference: 101344 (210%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 570 is the winner, and very much so. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 18112 (94%)

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 (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
