GeForce GTX 285 2GB vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has set the core speed at 2200 MHz. The GDDR6 memory is set to run at a speed of 2250 MHz on this model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 6500 XT		147456 MB/sec
	Difference: 11520 (8%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 172%) better at anisotropic filtering than the GeForce GTX 285 2GB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 285 2GB		51840 Mtexels/sec
	Difference: 88960 (172%)

Pixel Rate

The Radeon RX 6500 XT should be a lot (about 240%) faster with regards to anti-aliasing than the GeForce GTX 285 2GB, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 49664 (240%)

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 transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
