Radeon RX 460 2GB vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which has core clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 258192 (423%)

Pixel Rate

The Radeon RX Vega 64 will be quite a bit (approximately 358%) better at full screen anti-aliasing than the Radeon RX 460 2GB, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 62368 (358%)

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 (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
