GeForce 8300 GS (OEM) vs Radeon HD 5830

Intro

Compare those specifications to the Radeon HD 5830, which makes use of a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific model. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
Radeon HD 5830		175 Watts
	Difference: 135 Watts (338%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 should perform a lot faster than the GeForce 8300 GS (OEM) in general. (explain)

Radeon HD 5830		128000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 121600 (1900%)

Texel Rate

The Radeon HD 5830 should be quite a bit (more or less 2389%) better at anisotropic 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

If using high levels of AA is important to you, then the Radeon HD 5830 is the winner, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
