GeForce GTX 470 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which features a GPU core clock speed of 2200 MHz, and 4096 MB of GDDR6 memory set to run at 2250 MHz through a 64-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 470		215 Watts
	Difference: 108 Watts (101%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT should be 10% faster than the GeForce GTX 470 overall, due to its greater bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 470		133920 MB/sec
	Difference: 13536 (10%)

Texel Rate

The Radeon RX 6500 XT is quite a bit (more or less 314%) more effective at anisotropic filtering than the GeForce GTX 470. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 106808 (314%)

Pixel Rate

The Radeon RX 6500 XT will be much (more or less 190%) better at full screen anti-aliasing than the GeForce GTX 470, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 470		24280 Mpixels/sec
	Difference: 46120 (190%)

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 (in units of megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 are processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
