VS

GeForce GT 130 vs Radeon HD 5450

Intro

The GeForce GT 130 comes with core clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 RAM. It features 48 SPUs along with 24 TAUs and 16 ROPs.

Compare all of that to the Radeon HD 5450, which features core speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450 19 Watts
GeForce GT 130 75 Watts
Difference: 56 Watts (295%)

Memory Bandwidth

The Radeon HD 5450, in theory, should perform a bit faster than the GeForce GT 130 in general. (explain)

Radeon HD 5450 12800 MB/sec
GeForce GT 130 12000 MB/sec
Difference: 800 (7%)

Texel Rate

The GeForce GT 130 is much (about 131%) more effective at anisotropic filtering than the Radeon HD 5450. (explain)

GeForce GT 130 12000 Mtexels/sec
Radeon HD 5450 5200 Mtexels/sec
Difference: 6800 (131%)

Pixel Rate

If using high levels of AA 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 5450 2600 Mpixels/sec
Difference: 5400 (208%)

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 data (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be 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 the texel rate, the better the graphics card will be at 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 graphics card could 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 the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
