GeForce 9800 GX2 vs Radeon HD 4350

Intro

Compare those specifications to the Radeon HD 4350, which has core clock speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce 9800 GX2		197 Watts
	Difference: 175 Watts (795%)

Memory Bandwidth

In theory, the GeForce 9800 GX2 should be 1500% quicker than the Radeon HD 4350 in general, because of its higher bandwidth. (explain)

GeForce 9800 GX2		128000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 120000 (1500%)

Texel Rate

The GeForce 9800 GX2 is quite a bit (more or less 1570%) faster with regards to texture filtering than the Radeon HD 4350. (explain)

GeForce 9800 GX2		76800 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 72200 (1570%)

Pixel Rate

The GeForce 9800 GX2 is much (about 735%) better at FSAA than the Radeon HD 4350, and also will be capable of handling higher resolutions better. (explain)

GeForce 9800 GX2		19200 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 16900 (735%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
