GeForce GT 240 GDDR5 vs GeForce GTX 590

Intro

Compare those specs to the GeForce GTX 590, which makes use of a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 RAM works at a speed of 855 MHz on this particular card. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5		70 Watts
GeForce GTX 590		365 Watts
	Difference: 295 Watts (421%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 590 should be 504% faster than the GeForce GT 240 GDDR5 overall, due to its greater bandwidth. (explain)

GeForce GTX 590		328320 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 273920 (504%)

Texel Rate

The GeForce GTX 590 should be quite a bit (approximately 341%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 590		77696 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 60096 (341%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 590 is superior to the GeForce GT 240 GDDR5, by far. (explain)

GeForce GTX 590		58272 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 53872 (1224%)

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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour 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 is also dependant on lots of 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.
