Radeon HD 5770 vs Radeon R9 M365X

Intro

The Radeon HD 5770 uses a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this specific model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Compare all that to the Radeon R9 M365X, which features a clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

The Radeon R9 M365X should be a small bit (approximately 9%) better at AF than the Radeon HD 5770. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 3000 (9%)

Pixel Rate

The Radeon R9 M365X should be a little bit (about 9%) better at AA than the Radeon HD 5770, and should be able to handle higher screen resolutions better. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 1200 (9%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
