Radeon HD 7950 3GB vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which uses a 7 nm design. AMD has set the core speed at 1670 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this card. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 5500		229376 MB/sec
	Difference: 10624 (5%)

Texel Rate

The Radeon RX 5500 is quite a bit (about 64%) more effective at AF than the Radeon HD 7950 3GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon HD 7950 3GB		89600 Mtexels/sec
	Difference: 57360 (64%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5500 is a better choice, and very much so. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon HD 7950 3GB		25600 Mpixels/sec
	Difference: 27840 (109%)

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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
