Radeon HD 5830 vs Radeon R9 M365X

Intro

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

Compare those specifications to the Radeon R9 M365X, which features core clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 5830 128000 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 56000 (78%)

Texel Rate

The Radeon HD 5830 will be a lot (more or less 21%) more effective at texture filtering than the Radeon R9 M365X. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 7800 (21%)

Pixel Rate

The Radeon R9 M365X is just a bit (approximately 16%) better at full screen anti-aliasing than the Radeon HD 5830, and will be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 2000 (16%)

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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
