GeForce GT 340 1GB vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which makes use of a 55 nm design. AMD has clocked the core frequency at 575 MHz. The DDR2 RAM is set to run at a frequency of 500 MHz on this particular card. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Radeon HD 4350		22 Watts
GeForce GT 340 1GB		69 Watts
	Difference: 47 Watts (214%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 340 1GB is 580% faster than the Radeon HD 4350 in general, because of its greater data rate. (explain)

GeForce GT 340 1GB		54400 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 46400 (580%)

Texel Rate

The GeForce GT 340 1GB should be much (about 283%) better at texture filtering than the Radeon HD 4350. (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 13000 (283%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 340 1GB is a better choice, and very much so. (explain)

GeForce GT 340 1GB		4400 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 2100 (91%)

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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
