GeForce GT 430 1GB vs Radeon HD 6850

Intro

Compare all of that to the Radeon HD 6850, which makes use of a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific card. It features 960 SPUs along with 48 TAUs and 32 Rasterization Operator Units.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 99200 (344%)

Texel Rate

The Radeon HD 6850 will be quite a bit (approximately 232%) faster with regards to AF than the GeForce GT 430 1GB. (explain)

Radeon HD 6850		37200 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 26000 (232%)

Pixel Rate

The Radeon HD 6850 should be much (more or less 786%) more effective at FSAA than the GeForce GT 430 1GB, and will be capable of handling higher screen resolutions better. (explain)

Radeon HD 6850		24800 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 22000 (786%)

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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
