GeForce GT 130 vs Radeon HD 6450 (OEM)

Intro

The GeForce GT 130 uses a 55 nm design. nVidia has clocked the core speed at 500 MHz. The DDR2 memory is set to run at a frequency of 250 MHz on this specific model. It features 48 SPUs along with 24 Texture Address Units 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 speed of 800 MHz on this model. It features 160 SPUs as well as 8 Texture Address Units and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
