Radeon HD 4550 256MB vs Radeon R7 M260

Intro

The Radeon HD 4550 256MB has core clock speeds of 600 MHz on the GPU, and 800 MHz on the 256 MB of DDR3 memory. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Compare those specifications to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 memory works at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

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

Texel Rate

The Radeon R7 M260 will be much (approximately 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

The Radeon R7 M260 will be quite a bit (more or less 138%) more effective at anti-aliasing than the Radeon HD 4550 256MB, and able to handle higher resolutions more effectively. (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 transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
