GeForce GT 130 vs Radeon HD 5450

Intro

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

Compare those specs to the Radeon HD 5450, which has a clock speed of 650 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit memory bus, and uses a 40 nm design. It is comprised of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

GeForce GT 130 12000 MB/sec
Difference: 800 (7%)

Texel Rate

The GeForce GT 130 will be much (more or less 131%) more effective at AF 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 information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
