The NVIDIA GeForce GT 240 is one of the first slew of NVIDIA GPUs to be fabricated using the 40 nm process technology. It is also one of the first NVIDIA GPUs to support DirectX 10.1, which NVIDIA eschewed earlier as a pointless feature. We wonder what changed their minds...
In the past, NVIDIA would have added these minor improvements to their mid- to high-end offerings, but this time, they chose to try the 40 nm process technology and DirectX 10.1 in their latest low-end GPUs. The trio of GeForce GT 240, GeForce GT 220 and the GeForce 210 are all aimed at the value end of the market.
The GeForce GT 240 is a derivative of the GT200 GPU that powers the GeForce GTX 280 and the GeForce GTX 260. It is a slimmed-down version that features 96 stream processors and 8 ROPs. At the official core speed of 550 MHz, it is capable of processing up to 17.6 billion texels and 4.4 billion pixels per second.
The GeForce GT 240 GPU can be paired with a variety of memory, from DDR3 to GDDR5. Officially, the GeForce GT 240 can either use 900 MHz DDR3, 1 GHz GDDR3 or 850 MHz GDDR5 memory, delivering anywhere from 28.8 GB/s to 54.4 GB/s of memory bandwidth. This allows card vendors to provide a mixed bag of GeForce GT 240 cards with a variety of performance levels and costs.
Galaxy, being Galaxy, is never satisfied with sticking to the official specifications. Even though they are not officially calling this a factory-overclocked card, Galaxy gave their GeForce GT 240 (DDR5) card a slight boost in memory clock speed, going from 850 MHz to 900 MHz. This gives it a slight (5.88%) increase in memory bandwidth. Let's take a look and see how it compares against the official GeForce GT 240 and several other graphics cards.
