GeForce GT 320 vs Radeon HD 3650 512MB

Intro

The GeForce GT 320 makes use of a 40 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 memory runs at a frequency of 790 MHz on this particular model. It features 72 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the Radeon HD 3650 512MB, which has core speeds of 725 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
