GeForce GT 130 vs Radeon HD 6450 (OEM)

Intro

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

Compare those specs to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. AMD has clocked the core speed at 625 MHz. The GDDR3 memory is set to run at a frequency of 800 MHz on this particular card. It features 160 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
