GeForce GTX 1650 vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which has a core clock frequency of 1247 MHz and a HBM2 memory frequency of 1890 MHz. It also features a 2048-bit memory bus, and makes use of a 14 nm design. It is made up of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon RX Vega 64		295 Watts
	Difference: 220 Watts (293%)

Memory Bandwidth

Performance-wise, the Radeon RX Vega 64 should theoretically be a lot better than the GeForce GTX 1650 overall. (explain)

Radeon RX Vega 64		495411 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 364339 (278%)

Texel Rate

The Radeon RX Vega 64 will be quite a bit (more or less 284%) more effective at anisotropic filtering than the GeForce GTX 1650. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 236072 (284%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX Vega 64 is a better choice, by far. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
