GeForce GTX 280 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which features a clock speed of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 64-bit memory bus, and uses a 6 nm design. It features 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 280		236 Watts
	Difference: 129 Watts (121%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT is 4% faster than the GeForce GTX 280 in general, because of its greater bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 280		141696 MB/sec
	Difference: 5760 (4%)

Texel Rate

The Radeon RX 6500 XT will be much (more or less 192%) faster with regards to anisotropic filtering than the GeForce GTX 280. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 280		48160 Mtexels/sec
	Difference: 92640 (192%)

Pixel Rate

The Radeon RX 6500 XT is a lot (more or less 265%) faster with regards to full screen anti-aliasing than the GeForce GTX 280, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 51136 (265%)

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 (in units of MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
