GeForce 8600 GT 1GB DDR2 vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which comes with a core clock speed of 1156 MHz and a HBM2 memory speed of 1600 MHz. It also features a 2048-bit bus, and makes use of a 14 nm design. It features 3584 SPUs, 224 Texture Address Units, and 64 ROPs.

GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 406630 (3177%)

Texel Rate

The Radeon RX Vega 56 is a lot (more or less 2897%) better at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 250304 (2897%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX Vega 56 is a better choice, by a large margin. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 69664 (1613%)

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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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