Radeon RX 5700 vs Radeon RX Vega 64

Intro

The Radeon RX 5700 comes with a clock frequency of 1465 MHz and a GDDR6 memory speed of 14000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 64 ROPs.

Compare all that to the Radeon RX Vega 64, which features clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Radeon RX 5700 458752 MB/sec
Difference: 36659 (8%)

Texel Rate

The Radeon RX Vega 64 is a lot (more or less 51%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

Radeon RX Vega 64 319232 Mtexels/sec
Radeon RX 5700 210960 Mtexels/sec
Difference: 108272 (51%)

Pixel Rate

The Radeon RX 5700 should be a small bit (more or less 17%) more effective at FSAA than the Radeon RX Vega 64, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5700 93760 Mpixels/sec
Radeon RX Vega 64 79808 Mpixels/sec
Difference: 13952 (17%)

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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
