GeForce GT 340 1GB vs GeForce GTX 260

Intro

Compare those specifications to the GeForce GTX 260, which comes with clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 192 SPUs as well as 64 TAUs and 28 ROPs.

GeForce GT 340 1GB		69 Watts
GeForce GTX 260		182 Watts
	Difference: 113 Watts (164%)

Memory Bandwidth

The GeForce GTX 260, in theory, should be quite a bit faster than the GeForce GT 340 1GB in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 57488 (106%)

Texel Rate

The GeForce GTX 260 will be a lot (more or less 109%) more effective at AF than the GeForce GT 340 1GB. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 19264 (109%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 260 is the winner, by far. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 11728 (267%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling 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 the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of 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.
