GeForce GT 340 1GB vs GeForce GTX 275

Intro

Compare all of that to the GeForce GTX 275, which makes use of a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 RAM works at a frequency of 1134 MHz on this card. It features 240 SPUs along with 80 TAUs and 28 ROPs.

GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 33040 (188%)

Pixel Rate

The GeForce GTX 275 will be much (approximately 303%) faster with regards to full screen anti-aliasing than the GeForce GT 340 1GB, and also capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 275		17724 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 13324 (303%)

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 data (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
