GeForce GT 430 1GB vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific card. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
Radeon HD 5830		175 Watts
	Difference: 115 Watts (192%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 should be a lot faster than the GeForce GT 430 1GB overall. (explain)

Radeon HD 5830		128000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 99200 (344%)

Texel Rate

The Radeon HD 5830 is quite a bit (about 300%) more effective at anisotropic filtering than the GeForce GT 430 1GB. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 33600 (300%)

Pixel Rate

The Radeon HD 5830 will be quite a bit (more or less 357%) more effective at FSAA than the GeForce GT 430 1GB, and should be able to handle higher resolutions better. (explain)

Radeon HD 5830		12800 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 10000 (357%)

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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
