Radeon HD 6750 vs Radeon RX 580

Intro

The Radeon HD 6750 features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon RX 580, which makes use of a 14 nm design. AMD has clocked the core frequency at 1257 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this specific model. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Radeon HD 6750 64000 MB/sec
Difference: 198144 (310%)

Texel Rate

The Radeon RX 580 will be much (approximately 594%) more effective at texture filtering than the Radeon HD 6750. (explain)

Radeon RX 580 181008 Mtexels/sec
Radeon HD 6750 26100 Mtexels/sec
Difference: 154908 (594%)

Pixel Rate

The Radeon RX 580 should be quite a bit (more or less 247%) faster with regards to AA than the Radeon HD 6750, and also should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 580 40224 Mpixels/sec
Radeon HD 6750 11600 Mpixels/sec
Difference: 28624 (247%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better 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 amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
