Radeon HD 7950 3GB vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which features a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM set to run at 1500 MHz through a 192-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon HD 7950 3GB		200 Watts
	Difference: 50 Watts (33%)

Memory Bandwidth

In theory, the Radeon RX 5600 will be 23% faster than the Radeon HD 7950 3GB in general, because of its greater data rate. (explain)

Radeon RX 5600		294912 MB/sec
Radeon HD 7950 3GB		240000 MB/sec
	Difference: 54912 (23%)

Texel Rate

The Radeon RX 5600 will be quite a bit (about 96%) more effective at anisotropic filtering than the Radeon HD 7950 3GB. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 7950 3GB		89600 Mtexels/sec
	Difference: 86400 (96%)

Pixel Rate

The Radeon RX 5600 should be quite a bit (more or less 244%) more effective at full screen anti-aliasing than the Radeon HD 7950 3GB, and also capable of handling higher resolutions better. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7950 3GB		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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 maximum fill rate.
