Radeon HD 5770 vs Radeon R9 M375

Intro

The Radeon HD 5770 comes with a GPU core clock speed of 850 MHz, and the 1024 MB of GDDR5 memory is set to run at 1200 MHz through a 128-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon R9 M375, which has clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 5770 should theoretically be quite a bit superior to the Radeon R9 M375 in general. (explain)

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

Texel Rate

The Radeon R9 M375 should be a small bit (approximately 19%) better 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

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375 is a better choice, though not by far. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
