GeForce GT 220 GDDR3 vs Radeon HD 3690/3830

Intro

The GeForce GT 220 GDDR3 has a GPU clock speed of 625 MHz, and the 512 MB of GDDR3 RAM is set to run at 1012 MHz through a 128-bit bus. It also is made up of 48 Stream Processors, 16 TAUs, and 8 ROPs.

Compare all that to the Radeon HD 3690/3830, which makes use of a 55 nm design. AMD has clocked the core frequency at 668 MHz. The GDDR3 RAM works at a frequency of 828 MHz on this specific model. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
