Radeon RX 5700 XT vs Radeon RX Vega 64

Intro

The Radeon RX 5700 XT comes with a GPU clock speed of 1605 MHz, and the 8096 MB of GDDR6 memory is set to run at 1750 MHz through a 256-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core speed at 1247 MHz. The HBM2 memory works at a speed of 1890 MHz on this particular model. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT 225 Watts
Radeon RX Vega 64 295 Watts
Difference: 70 Watts (31%)

Memory Bandwidth

The Radeon RX Vega 64, in theory, should be just a bit faster than the Radeon RX 5700 XT overall. (explain)

Radeon RX Vega 64 495411 MB/sec
Radeon RX 5700 XT 458752 MB/sec
Difference: 36659 (8%)

Texel Rate

The Radeon RX Vega 64 will be quite a bit (about 24%) more effective at AF than the Radeon RX 5700 XT. (explain)

Radeon RX Vega 64 319232 Mtexels/sec
Radeon RX 5700 XT 256800 Mtexels/sec
Difference: 62432 (24%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5700 XT is superior to the Radeon RX Vega 64, by a large margin. (explain)

Radeon RX 5700 XT 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
