Geforce GTX 1080 Ti vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has set the core frequency at 2200 MHz. The GDDR6 RAM works at a speed of 2250 MHz on this model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 143 Watts (134%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 1080 Ti should be 236% faster than the Radeon RX 6500 XT in general, because of its greater data rate. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 348160 (236%)

Texel Rate

The Geforce GTX 1080 Ti is a lot (about 135%) faster with regards to AF than the Radeon RX 6500 XT. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 190720 (135%)

Pixel Rate

The Geforce GTX 1080 Ti is quite a bit (more or less 85%) more effective at anti-aliasing than the Radeon RX 6500 XT, and should be able to handle higher resolutions without losing too much performance. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 6500 XT		70400 Mpixels/sec
	Difference: 59840 (85%)

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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range 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 number of texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
