Radeon HD 5770 vs Radeon R9 M375

Intro

The Radeon HD 5770 comes with core speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon R9 M375, which features a clock frequency of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5770 should be quite a bit faster than the Radeon R9 M375 overall. (explain)

Radeon HD 5770 76800 MB/sec
Radeon R9 M375 35200 MB/sec
Difference: 41600 (118%)

Texel Rate

The Radeon R9 M375 should be just a bit (more or less 19%) more effective at texture filtering than the Radeon HD 5770. (explain)

Radeon R9 M375 40600 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 6600 (19%)

Pixel Rate

The Radeon R9 M375 will be a little bit (about 19%) faster with regards to AA than the Radeon HD 5770, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M375 16240 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 2640 (19%)

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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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