Radeon HD 5550 vs Radeon R9 M375X

Intro

The Radeon HD 5550 makes use of a 40 nm design. AMD has clocked the core frequency at 550 MHz. The DDR2 memory works at a speed of 400 MHz on this specific card. It features 320(64x5) SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the Radeon R9 M375X, which has core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be 463% quicker than the Radeon HD 5550 overall, due to its higher bandwidth. (explain)

Radeon R9 M375X 72000 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 59200 (463%)

Texel Rate

The Radeon R9 M375X will be quite a bit (approximately 361%) faster with regards to texture filtering than the Radeon HD 5550. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 31800 (361%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375X is the winner, by a large margin. (explain)

Radeon R9 M375X 16240 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 11840 (269%)

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 across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 in one 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. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on many 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.
