GeForce GTX 275 vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has set the core frequency at 2200 MHz. The GDDR6 RAM runs at a frequency of 2250 MHz on this model. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 275		219 Watts
	Difference: 112 Watts (105%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT will be 16% faster than the GeForce GTX 275 overall, due to its greater bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 275		127008 MB/sec
	Difference: 20448 (16%)

Texel Rate

The Radeon RX 6500 XT will be much (more or less 178%) more effective at anisotropic filtering than the GeForce GTX 275. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 90160 (178%)

Pixel Rate

The Radeon RX 6500 XT will be quite a bit (approximately 297%) better at FSAA than the GeForce GTX 275, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 52676 (297%)

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. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at 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 card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
