Radeon HD 5830 vs Radeon R9 M390X

Intro

The Radeon HD 5830 makes use of a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this card. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M390X, which features core clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Radeon HD 5830 128000 MB/sec
Difference: 32000 (25%)

Texel Rate

The Radeon R9 M390X is quite a bit (more or less 107%) more effective at texture filtering than the Radeon HD 5830. (explain)

Radeon R9 M390X 92544 Mtexels/sec
Radeon HD 5830 44800 Mtexels/sec
Difference: 47744 (107%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M390X is the winner, by far. (explain)

Radeon R9 M390X 23136 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 10336 (81%)

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: Bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
