GeForce GTX 1630 vs Radeon RX Vega 64

Intro

Compare those specifications to the Radeon RX Vega 64, which features GPU core speed of 1247 MHz, and 8192 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also is comprised of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

GeForce GTX 1630		55680 Mtexels/sec
	Difference: 263552 (473%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX Vega 64 is a better choice, by a large margin. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 51968 (187%)

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 information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
