Geforce GTX 770 vs Radeon RX 6950 XT

Intro

Compare those specifications to the Radeon RX 6950 XT, which uses a 7 nm design. AMD has set the core speed at 1925 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this specific model. It features 5120 SPUs as well as 320 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 770		230 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 105 Watts (46%)

Memory Bandwidth

The Radeon RX 6950 XT should in theory perform quite a bit faster than the Geforce GTX 770 overall. (explain)

Radeon RX 6950 XT		589824 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 365440 (163%)

Texel Rate

The Radeon RX 6950 XT should be a lot (more or less 360%) better at anisotropic filtering than the Geforce GTX 770. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 482112 (360%)

Pixel Rate

The Radeon RX 6950 XT is much (more or less 636%) faster with regards to full screen anti-aliasing than the Geforce GTX 770, and will be able to handle higher resolutions while still performing well. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 212928 (636%)

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 data (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
