GeForce GT 340 vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which comes with GPU core speed of 725 MHz, and 512 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 720 SPUs, 36 TAUs, and 16 ROPs.

GeForce GT 340		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The Radeon HD 6750 is a lot (approximately 48%) faster with regards to AF than the GeForce GT 340. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 8500 (48%)

Pixel Rate

The Radeon HD 6750 should be much (about 164%) more effective at AA than the GeForce GT 340, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 7200 (164%)

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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it 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 applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
