Radeon HD 5830 vs Radeon R9 M395X

Intro

The Radeon HD 5830 has a clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 1120(224x5) SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has clocked the core frequency at 723 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this specific model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock 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 processed in one second.

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