VS

Radeon RX 6900 XT vs Radeon Vega Frontier Edition

Intro

The Radeon RX 6900 XT uses a 7 nm design. AMD has clocked the core frequency at 1825 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this particular model. It features 5120 SPUs as well as 320 Texture Address Units and 128 Rasterization Operator Units.

Compare those specifications to the Radeon Vega Frontier Edition, which uses a 14 nm design. AMD has set the core speed at 1382 MHz. The HBM2 memory works at a frequency of 1890 MHz on this specific model. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6900 XT should theoretically perform a small bit faster than the Radeon Vega Frontier Edition in general. (explain)

Radeon RX 6900 XT 524288 MB/sec
Radeon Vega Frontier Edition 495452 MB/sec
Difference: 28836 (6%)

Texel Rate

The Radeon RX 6900 XT is quite a bit (about 65%) better at AF than the Radeon Vega Frontier Edition. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Radeon Vega Frontier Edition 353792 Mtexels/sec
Difference: 230208 (65%)

Pixel Rate

The Radeon RX 6900 XT should be a lot (about 164%) more effective at anti-aliasing than the Radeon Vega Frontier Edition, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
Radeon Vega Frontier Edition 88448 Mpixels/sec
Difference: 145152 (164%)

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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
