Radeon RX 6750 XT vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which features a clock frequency of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also features a 4096-bit memory bus, and makes use of a 7 nm design. It is made up of 3840 SPUs, 240 Texture Address Units, and 64 Raster Operation Units.

The Radeon VII should in theory be much faster than the Radeon RX 6750 XT in general. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 606208 (137%)

Texel Rate

The Radeon RX 6750 XT will be a bit (more or less 2%) faster with regards to texture filtering than the Radeon VII. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon VII		336000 Mtexels/sec
	Difference: 8000 (2%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6750 XT is superior to the Radeon VII, by a large margin. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 48000 (54%)

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 maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
