GeForce GTX 750 Ti vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which comes with a clock speed of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 64-bit bus, and makes use of a 6 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 47 Watts (78%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT should be 71% faster than the GeForce GTX 750 Ti in general, because of its greater bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 61056 (71%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 245%) more effective at texture filtering than the GeForce GTX 750 Ti. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 100000 (245%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6500 XT is superior to the GeForce GTX 750 Ti, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 54080 (331%)

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 information (measured in megabytes per second) that can be transferred 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 it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
