Radeon HD 4870 512MB vs Radeon R9 Fury X


Intro

The Radeon HD 4870 512MB uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this specific model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare all that to the Radeon R9 Fury X, which has a clock frequency of 1050 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit bus, and uses a 28 nm design. It is made up of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum 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
