Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.

Lol its comical at how superior the Fury X is to old GPUs like the HD4870. I don't understand why AMD gets a bad rap. Their GPUs have improved so immensely that the games literally can't even demonstrate the vast performance gap. The Fury X is still held back by software. Just look at benchmarks of Doom Vulkan ultra. It outperforms GPUs like the GTX1070 still. Its comical that reviewers even try to compare GPUs with such performance gaps and try to say the GTX1070 is better than the Fury X or GTX980Ti.

The software itself is holding back hardware of this level
