Radeon HD 4550 256MB vs Radeon R7 M260

Intro

The Radeon HD 4550 256MB makes use of a 55 nm design. AMD has clocked the core frequency at 600 MHz. The DDR3 RAM runs at a frequency of 800 MHz on this specific model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Compare those specifications to the Radeon R7 M260, which comes with GPU core speed of 715 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260 will be 25% faster than the Radeon HD 4550 256MB in general, because of its higher bandwidth. (explain)

Radeon R7 M260 16000 MB/sec
Radeon HD 4550 256MB 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R7 M260 will be much (more or less 258%) more effective at texture filtering than the Radeon HD 4550 256MB. (explain)

Radeon R7 M260 17160 Mtexels/sec
Radeon HD 4550 256MB 4800 Mtexels/sec
Difference: 12360 (258%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 M260 is a better choice, and very much so. (explain)

Radeon R7 M260 5720 Mpixels/sec
Radeon HD 4550 256MB 2400 Mpixels/sec
Difference: 3320 (138%)

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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
