GeForce GT 340 1GB vs Radeon HD 3850 512MB

Intro

The GeForce GT 340 1GB comes with a clock speed of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 Texture Address Units, and 8 ROPs.

Compare those specs to the Radeon HD 3850 512MB, which has core clock speeds of 668 MHz on the GPU, and 828 MHz on the 512 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. 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 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 reach the maximum fill rate.
