GeForce 8800 GT 512MB vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which has a clock frequency of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

Performance-wise, the Radeon RX 6800 should theoretically be quite a bit superior to the GeForce 8800 GT 512MB in general. (explain)

Radeon RX 6800		524288 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 466688 (810%)

Texel Rate

The Radeon RX 6800 will be quite a bit (about 1114%) faster with regards to texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 374400 (1114%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6800 is superior to the GeForce 8800 GT 512MB, and very much so. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 153600 (1600%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
