GeForce GTS 450 vs Radeon HD 4350

Intro

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

Texel Rate

The GeForce GTS 450 should be much (about 445%) more effective at texture filtering than the Radeon HD 4350. (explain)

GeForce GTS 450		25056 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 20456 (445%)

Pixel Rate

The GeForce GTS 450 is quite a bit (approximately 445%) faster with regards to full screen anti-aliasing than the Radeon HD 4350, and should be capable of handling higher screen resolutions better. (explain)

GeForce GTS 450		12528 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 10228 (445%)

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 data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 texture map elements (texels) that can be processed in one second. This number 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
