Radeon HD 7750 vs Radeon RX 570

Intro

Compare all of that to the Radeon RX 570, which comes with a GPU core clock speed of 1168 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Radeon HD 7750		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 570 should be quite a bit (more or less 484%) faster with regards to AF than the Radeon HD 7750. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 123904 (484%)

Pixel Rate

The Radeon RX 570 will be a lot (approximately 192%) more effective at full screen anti-aliasing than the Radeon HD 7750, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 570		37376 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 24576 (192%)

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 (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high 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 texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel 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.
