GeForce RTX 2070 Super vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which features a clock frequency of 1247 MHz and a HBM2 memory speed of 1890 MHz. It also features a 2048-bit bus, and uses a 14 nm design. It is made up of 4096 SPUs, 256 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070 Super		215 Watts
Radeon RX Vega 64		295 Watts
	Difference: 80 Watts (37%)

Memory Bandwidth

The Radeon RX Vega 64 should in theory be a bit faster than the GeForce RTX 2070 Super in general. (explain)

Radeon RX Vega 64		495411 MB/sec
GeForce RTX 2070 Super		458752 MB/sec
	Difference: 36659 (8%)

Texel Rate

The Radeon RX Vega 64 should be quite a bit (approximately 24%) more effective at anisotropic filtering than the GeForce RTX 2070 Super. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 62432 (24%)

Pixel Rate

The GeForce RTX 2070 Super is a lot (approximately 29%) better at full screen anti-aliasing than the Radeon RX Vega 64, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 22912 (29%)

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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
