GeForce GT 130 vs Radeon HD 6450 (OEM)

Intro

The GeForce GT 130 makes use of a 55 nm design. nVidia has clocked the core speed at 500 MHz. The DDR2 RAM runs at a speed of 250 MHz on this particular model. It features 48 SPUs along with 24 TAUs and 16 ROPs.

Compare those specifications to the Radeon HD 6450 (OEM), which comes with a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 RAM set to run at 800 MHz through a 64-bit bus. It also is comprised of 160 SPUs, 8 TAUs, and 4 ROPs.

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

Texel Rate

The GeForce GT 130 is quite a bit (about 140%) better at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)

GeForce GT 130 12000 Mtexels/sec
Radeon HD 6450 (OEM) 5000 Mtexels/sec
Difference: 7000 (140%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 130 is the winner, by far. (explain)

GeForce GT 130 8000 Mpixels/sec
Radeon HD 6450 (OEM) 2500 Mpixels/sec
Difference: 5500 (220%)

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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
