GeForce GTX 650 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which has core speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 memory. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 43 Watts (67%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT should be much faster than the GeForce GTX 650 in general. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 67456 (84%)

Texel Rate

The Radeon RX 6500 XT is quite a bit (about 316%) more effective at texture filtering than the GeForce GTX 650. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 106944 (316%)

Pixel Rate

The Radeon RX 6500 XT is a lot (more or less 316%) better at FSAA than the GeForce GTX 650, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 53472 (316%)

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 MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher 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 could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
