Radeon HD 5550 vs Radeon HD 6450 (OEM)

Intro

The Radeon HD 5550 uses a 40 nm design. AMD has set the core speed at 550 MHz. The DDR2 memory runs at a speed of 400 MHz on this particular model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare those specifications to the Radeon HD 6450 (OEM), which features a clock frequency of 625 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 64-bit memory bus, and uses a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon HD 5550 is a lot (about 76%) faster with regards to texture filtering than the Radeon HD 6450 (OEM). (explain)

Radeon HD 5550 8800 Mtexels/sec
Radeon HD 6450 (OEM) 5000 Mtexels/sec
Difference: 3800 (76%)

Pixel Rate

The Radeon HD 5550 should be a lot (more or less 76%) faster with regards to FSAA than the Radeon HD 6450 (OEM), and able to handle higher screen resolutions better. (explain)

Radeon HD 5550 4400 Mpixels/sec
Radeon HD 6450 (OEM) 2500 Mpixels/sec
Difference: 1900 (76%)

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 (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
