GeForce 8300 GS (OEM) vs Radeon HD 5830

Intro

The GeForce 8300 GS (OEM) features core speeds of 450 MHz on the GPU, and 400 MHz on the 128 MB of DDR2 RAM. It features 8 SPUs as well as 4 TAUs and 2 ROPs.

Compare those specifications to the Radeon HD 5830, which features a clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is made up of 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

GeForce 8300 GS (OEM) 6400 MB/sec
Difference: 121600 (1900%)

Texel Rate

The Radeon HD 5830 should be a lot (approximately 2389%) faster with regards to texture filtering than the GeForce 8300 GS (OEM). (explain)

Radeon HD 5830 44800 Mtexels/sec
GeForce 8300 GS (OEM) 1800 Mtexels/sec
Difference: 43000 (2389%)

Pixel Rate

The Radeon HD 5830 will be quite a bit (more or less 1322%) better at anti-aliasing than the GeForce 8300 GS (OEM), and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 5830 12800 Mpixels/sec
GeForce 8300 GS (OEM) 900 Mpixels/sec
Difference: 11900 (1322%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied in one second. This number 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 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 the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
