Radeon HD 5550 vs Radeon R7 M260X

Intro

The Radeon HD 5550 comes with a core clock frequency of 550 MHz and a DDR2 memory speed of 400 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 320(64x5) SPUs, 16 TAUs, and 8 ROPs.

Compare all of that to the Radeon R7 M260X, which has a core clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X is 400% quicker than the Radeon HD 5550 overall, because of its greater bandwidth. (explain)

Radeon R7 M260X 64000 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 51200 (400%)

Texel Rate

The Radeon R7 M260X will be quite a bit (about 125%) more effective at texture filtering than the Radeon HD 5550. (explain)

Radeon R7 M260X 19800 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 11000 (125%)

Pixel Rate

The Radeon R7 M260X will be a lot (approximately 50%) better at anti-aliasing than the Radeon HD 5550, and also able to handle higher resolutions while still performing well. (explain)

Radeon R7 M260X 6600 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 2200 (50%)

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 transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units 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 per 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. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
