GeForce 8800 GT 512MB vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which has GPU core speed of 1156 MHz, and 8192 MB of HBM2 RAM running at 1600 MHz through a 2048-bit bus. It also is comprised of 3584 SPUs, 224 TAUs, and 64 ROPs.

GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 361830 (628%)

Texel Rate

The Radeon RX Vega 56 will be much (about 671%) faster with regards to texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 225344 (671%)

Pixel Rate

The Radeon RX Vega 56 should be quite a bit (approximately 671%) more effective at AA than the GeForce 8800 GT 512MB, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 64384 (671%)

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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount 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 in a second.

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