GeForce GT 130 vs Radeon HD 5550

Intro

The GeForce GT 130 features a GPU core clock speed of 500 MHz, and the 768 MB of DDR2 memory runs at 250 MHz through a 192-bit bus. It also features 48 Stream Processors, 24 TAUs, and 16 ROPs.

Compare all of that to the Radeon HD 5550, which makes use of a 40 nm design. AMD has clocked the core speed at 550 MHz. The DDR2 RAM runs at a speed of 400 MHz on this specific card. It features 320(64x5) SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5550 should be 7% quicker than the GeForce GT 130 overall, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GT 130 should be much (about 36%) faster with regards to texture filtering than the Radeon HD 5550. (explain)

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

Pixel Rate

The GeForce GT 130 should be quite a bit (about 82%) better at full screen anti-aliasing than the Radeon HD 5550, and also able to handle higher screen resolutions while still performing well. (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 largest amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to reach the maximum fill rate.
