Radeon HD 7990 vs Radeon Vega Frontier Edition

Intro

The Radeon HD 7990 has a clock speed of 950 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon Vega Frontier Edition, which makes use of a 14 nm design. AMD has clocked the core frequency at 1382 MHz. The HBM2 RAM runs at a frequency of 1890 MHz on this particular model. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon Vega Frontier Edition is superior to the Radeon HD 7990, by far. (explain)

Radeon Vega Frontier Edition 88448 Mpixels/sec
Radeon HD 7990 60800 Mpixels/sec
Difference: 27648 (45%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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 max fill rate.
