Radeon HD 7950 vs Radeon RX 5600

Intro

Compare that to the Radeon RX 5600, which features GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon HD 7950		240000 MB/sec
	Difference: 54912 (23%)

Texel Rate

The Radeon RX 5600 should be quite a bit (approximately 96%) faster with regards to AF than the Radeon HD 7950. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 7950		89600 Mtexels/sec
	Difference: 86400 (96%)

Pixel Rate

The Radeon RX 5600 should be a lot (about 244%) better at FSAA than the Radeon HD 7950, and will be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 62400 (244%)

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 max amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
