Geforce GTX 780 vs Radeon HD 4350

Intro

Compare those specifications to the Radeon HD 4350, which has GPU core speed of 575 MHz, and 512 MB of DDR2 memory running at 500 MHz through a 64-bit bus. It also features 80(16x5) Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
Geforce GTX 780		250 Watts
	Difference: 228 Watts (1036%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 780 should perform quite a bit faster than the Radeon HD 4350 overall. (explain)

Geforce GTX 780		288384 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 280384 (3505%)

Texel Rate

The Geforce GTX 780 should be much (more or less 3502%) faster with regards to anisotropic filtering than the Radeon HD 4350. (explain)

Geforce GTX 780		165696 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 161096 (3502%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 780 is a better choice, by far. (explain)

Geforce GTX 780		41424 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 39124 (1701%)

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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
