GeForce GT 340 1GB vs GeForce GTX 295

Intro

Compare those specifications to the GeForce GTX 295, which has GPU core speed of 576 MHz, and 896 MB of GDDR3 RAM running at 999 MHz through a 448-bit bus. It also is made up of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 1GB		69 Watts
GeForce GTX 295		289 Watts
	Difference: 220 Watts (319%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 will be 311% quicker than the GeForce GT 340 1GB in general, due to its greater data rate. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 169376 (311%)

Texel Rate

The GeForce GTX 295 is quite a bit (more or less 424%) better at texture filtering than the GeForce GT 340 1GB. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 74560 (424%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 295 is the winner, and very much so. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 27856 (633%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
