GeForce GT 340 vs GeForce GTX 260

Intro

The GeForce GT 340 comes with clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 memory. It features 96 SPUs as well as 32 TAUs and 8 ROPs.

Compare all that to the GeForce GTX 260, which features core 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.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

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

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

Texel Rate

The GeForce GTX 260 should be much (about 109%) faster with regards to texture filtering than the GeForce GT 340. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 260 is a better choice, and very much so. (explain)

GeForce GTX 260 16128 Mpixels/sec
GeForce GT 340 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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount 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 that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
