GeForce GT 430 (OEM) vs Radeon HD 5830

Intro

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

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

Memory Bandwidth

In theory, the Radeon HD 5830 should be a lot faster than the GeForce GT 430 (OEM) in general. (explain)

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

Texel Rate

The Radeon HD 5830 will be much (more or less 300%) more effective at AF than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 5830 is a better choice, and very much so. (explain)

Radeon HD 5830		12800 Mpixels/sec
GeForce GT 430 (OEM)		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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
