GeForce GTX 1650 vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which comes with a GPU core clock speed of 1247 MHz, and 8192 MB of HBM2 memory running at 1890 MHz through a 2048-bit bus. It also features 4096 Stream Processors, 256 Texture Address Units, and 64 Raster Operation Units.

	Difference: 236072 (284%)

Pixel Rate

The Radeon RX Vega 64 will be a lot (approximately 68%) faster with regards to full screen anti-aliasing than the GeForce GTX 1650, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 32288 (68%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 this number, 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 worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
