Radeon HD 5750 1GB vs Radeon RX 570

Intro

Compare all of that to the Radeon RX 570, which comes with GPU clock speed of 1168 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 124304 (493%)

Pixel Rate

The Radeon RX 570 should be a lot (about 234%) better at anti-aliasing than the Radeon HD 5750 1GB, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 570		37376 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 26176 (234%)

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 maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
