Radeon RX 5700 XT 50th Anniversary Edition vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 memory runs at a frequency of 1890 MHz on this specific card. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
Radeon RX Vega 64		295 Watts
	Difference: 60 Watts (26%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 64 will be 8% quicker than the Radeon RX 5700 XT 50th Anniversary Edition in general, due to its higher data rate. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
	Difference: 36659 (8%)

Texel Rate

The Radeon RX Vega 64 should be just a bit (more or less 19%) more effective at anisotropic filtering than the Radeon RX 5700 XT 50th Anniversary Edition. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
	Difference: 50432 (19%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be a lot (more or less 35%) faster with regards to full screen anti-aliasing than the Radeon RX Vega 64, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 27712 (35%)

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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels 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 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
