GeForce 8600 GT 1GB DDR2 vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which comes with core speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB DDR2		47 Watts
Radeon RX Vega 56		210 Watts
	Difference: 163 Watts (347%)

Memory Bandwidth

In theory, the Radeon RX Vega 56 will be 3177% faster than the GeForce 8600 GT 1GB DDR2 overall, due to its higher data rate. (explain)

Radeon RX Vega 56		419430 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 406630 (3177%)

Texel Rate

The Radeon RX Vega 56 will be much (approximately 2897%) more effective at AF 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

The Radeon RX Vega 56 should be quite a bit (approximately 1613%) more effective at anti-aliasing than the GeForce 8600 GT 1GB DDR2, and should be able to handle higher resolutions while still performing well. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
