GeForce GT 130 vs Radeon HD 5550

Intro

The GeForce GT 130 features a core clock speed of 500 MHz and a DDR2 memory frequency of 250 MHz. It also makes use of a 192-bit memory bus, and makes use of a 55 nm design. It features 48 SPUs, 24 TAUs, and 16 ROPs.

Compare all that to the Radeon HD 5550, which has a core clock speed of 550 MHz and a DDR2 memory speed of 400 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 320(64x5) SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5550 is 7% quicker than the GeForce GT 130 in general, due to its higher bandwidth. (explain)

Radeon HD 5550 12800 MB/sec
GeForce GT 130 12000 MB/sec
Difference: 800 (7%)

Texel Rate

The GeForce GT 130 is quite a bit (approximately 36%) better at anisotropic filtering than the Radeon HD 5550. (explain)

GeForce GT 130 12000 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 3200 (36%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 130 is the winner, and very much so. (explain)

GeForce GT 130 8000 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 3600 (82%)

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 information (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
