GeForce GTX 560 Ti vs Radeon HD 4350

Intro

Compare all of that to the Radeon HD 4350, which comes with a GPU core clock speed of 575 MHz, and 512 MB of DDR2 memory running at 500 MHz through a 64-bit bus. It also is comprised of 80(16x5) Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 148 Watts (673%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti should be 1503% faster than the Radeon HD 4350 overall, because of its greater bandwidth. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 120256 (1503%)

Texel Rate

The GeForce GTX 560 Ti will be quite a bit (approximately 1044%) more effective at anisotropic filtering than the Radeon HD 4350. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 48008 (1044%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 560 Ti is a better choice, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 24004 (1044%)

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 max amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
