GeForce GT 340 vs Radeon HD 3850 256MB

Intro

The GeForce GT 340 has a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also is made up of 96 SPUs, 32 Texture Address Units, and 8 ROPs.

Compare those specifications to the Radeon HD 3850 256MB, which features a GPU core clock speed of 668 MHz, and 256 MB of GDDR3 memory running at 828 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling 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 write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
