GeForce 8300 GS (OEM) vs Radeon HD 5830

Intro

The GeForce 8300 GS (OEM) comes with a core clock speed of 450 MHz and a DDR2 memory speed of 400 MHz. It also features a 64-bit memory bus, and makes use of a 80 nm design. It is made up of 8 SPUs, 4 TAUs, and 2 Raster Operation Units.

Compare those specifications to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1000 MHz on this card. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
