GeForce 8800 GTS (G80) 640MB vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which comes with core speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 RAM. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Radeon RX 5500		150 Watts
	Difference: 7 Watts (5%)

Memory Bandwidth

In theory, the Radeon RX 5500 should perform quite a bit faster than the GeForce 8800 GTS (G80) 640MB in general. (explain)

Radeon RX 5500		229376 MB/sec
GeForce 8800 GTS (G80) 640MB		63360 MB/sec
	Difference: 166016 (262%)

Texel Rate

The Radeon RX 5500 is a lot (approximately 497%) better at anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce 8800 GTS (G80) 640MB		24624 Mtexels/sec
	Difference: 122336 (497%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 is the winner, by far. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce 8800 GTS (G80) 640MB		10260 Mpixels/sec
	Difference: 43180 (421%)

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 data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at 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 write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
