GeForce GTX 285 2GB vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which features a core clock speed of 2200 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 64-bit bus, and uses a 6 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 285 2GB		204 Watts
	Difference: 97 Watts (91%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 2GB will be 8% quicker than the Radeon RX 6500 XT in general, because of its higher data rate. (explain)

GeForce GTX 285 2GB		158976 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 11520 (8%)

Texel Rate

The Radeon RX 6500 XT is quite a bit (approximately 172%) faster with regards to texture 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 6500 XT is a better choice, and very much so. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 get to the max fill rate.
