Geforce GTX 770 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which features a core clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 770		230 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 70 Watts (30%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT is 134% faster than the Geforce GTX 770 overall, due to its higher data rate. (explain)

Radeon RX 6900 XT		524288 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 299904 (134%)

Texel Rate

The Radeon RX 6900 XT should be much (more or less 336%) more effective at texture filtering than the Geforce GTX 770. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 450112 (336%)

Pixel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 598%) better at AA than the Geforce GTX 770, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 200128 (598%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This number is worked out 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
