GeForce 8800 GT 512MB vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which comes with GPU core speed of 1500 MHz, and 20480 MB of GDDR6 RAM set to run at 2500 MHz through a 320-bit bus. It also is comprised of 5376 Stream Processors, 336 TAUs, and 192 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB		105 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 195 Watts (186%)

Memory Bandwidth

Performance-wise, the Radeon RX 7900 XT should in theory be much superior to the GeForce 8800 GT 512MB overall. (explain)

Radeon RX 7900 XT		819200 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 761600 (1322%)

Texel Rate

The Radeon RX 7900 XT is a lot (more or less 1400%) better at texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 470400 (1400%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 7900 XT is a better choice, and very much so. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 278400 (2900%)

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 (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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