GeForce GTX 650 vs Radeon RX 6750 XT

Intro

Compare those specifications to the Radeon RX 6750 XT, which makes use of a 7 nm design. AMD has set the core speed at 2150 MHz. The GDDR6 memory works at a speed of 2250 MHz on this specific card. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 186 Watts (291%)

Memory Bandwidth

The Radeon RX 6750 XT, in theory, should perform quite a bit faster than the GeForce GTX 650 in general. (explain)

Radeon RX 6750 XT		442368 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 362368 (453%)

Texel Rate

The Radeon RX 6750 XT should be much (approximately 916%) more effective at AF than the GeForce GTX 650. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 310144 (916%)

Pixel Rate

The Radeon RX 6750 XT will be much (more or less 713%) better at AA than the GeForce GTX 650, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 120672 (713%)

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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the 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 most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
