Radeon R7 260X vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which has a core clock frequency of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It is made up of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 260X		115 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 220 Watts (191%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6950 XT is 467% faster than the Radeon R7 260X in general, because of its greater bandwidth. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon R7 260X		104000 MB/sec
	Difference: 485824 (467%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (about 900%) more effective at AF than the Radeon R7 260X. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R7 260X		61600 Mtexels/sec
	Difference: 554400 (900%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6950 XT is a better choice, by far. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 228800 (1300%)

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 max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 maximum fill rate.
