VS

Radeon RX 6700 XT vs Radeon RX Vega 56

Intro

The Radeon RX 6700 XT comes with core clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 RAM. It features 2560 SPUs as well as 160 TAUs and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX Vega 56, which features clock speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs as well as 224 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX Vega 56 210 Watts
Radeon RX 6700 XT 230 Watts
Difference: 20 Watts (10%)

Memory Bandwidth

In theory, the Radeon RX Vega 56 should perform a bit faster than the Radeon RX 6700 XT in general. (explain)

Radeon RX Vega 56 419430 MB/sec
Radeon RX 6700 XT 393216 MB/sec
Difference: 26214 (7%)

Texel Rate

The Radeon RX 6700 XT should be a lot (about 43%) more effective at AF than the Radeon RX Vega 56. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
Radeon RX Vega 56 258944 Mtexels/sec
Difference: 112416 (43%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6700 XT is a better choice, and very much so. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
Radeon RX Vega 56 73984 Mpixels/sec
Difference: 74560 (101%)

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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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