GeForce GTX 780 Ti vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which has core clock speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 memory. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 143 Watts (134%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 780 Ti should be 128% faster than the Radeon RX 6500 XT overall, because of its greater data rate. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 188544 (128%)

Texel Rate

The GeForce GTX 780 Ti will be a lot (about 49%) faster with regards to AF than the Radeon RX 6500 XT. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 69200 (49%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6500 XT is the winner, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 28400 (68%)

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 data (measured in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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.
