Radeon RX 6700 XT vs Radeon RX 6750 XT

Intro

Compare those specifications to the Radeon RX 6750 XT, which has a core clock speed of 2150 MHz and a GDDR6 memory frequency of 2250 MHz. It also uses a 192-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6700 XT		230 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 20 Watts (9%)

Memory Bandwidth

Theoretically, the Radeon RX 6750 XT should perform a little bit faster than the Radeon RX 6700 XT overall. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon RX 6700 XT		393216 MB/sec
	Difference: 49152 (13%)

Texel Rate

The Radeon RX 6700 XT should be just a bit (more or less 8%) better at texture filtering than the Radeon RX 6750 XT. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 27360 (8%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6700 XT is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 10944 (8%)

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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is 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 ANOTHER 2x. 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
