GeForce GTX 285 1GB vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has set the core frequency at 2200 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this card. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 285 1GB		204 Watts
	Difference: 97 Watts (91%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 1GB will be 8% faster than the Radeon RX 6500 XT in general, because of its greater bandwidth. (explain)

GeForce GTX 285 1GB		158976 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 11520 (8%)

Texel Rate

The Radeon RX 6500 XT is a lot (about 172%) more effective at texture filtering than the GeForce GTX 285 1GB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 285 1GB		51840 Mtexels/sec
	Difference: 88960 (172%)

Pixel Rate

The Radeon RX 6500 XT should be much (more or less 240%) faster with regards to anti-aliasing than the GeForce GTX 285 1GB, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 285 1GB		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 largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 can be applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
