This is very important, as GDDR5 offers two times the theoretical memory bandwidth per clock compared to DDR2 or GDDR3. While the GeForce GT 220 is limited to DDR2 and GDDR3, the new GeForce GT 240 can be coupled with either DDR3 or GDDR5.

The biggest differentiator favoring Nvidia's GeForce GT 240 is its memory support. As a result, the GTX 285 sports a total of 240 processor cores, 80 texture units, and eight ROPs capable of handling 64 pixels per clock, with all of the ROPs contributing to a 512-bit memory bus. There are eight 64-bit raster-operator partitions (ROPs) capable of handling eight raster operations per clock cycle each. Each TPC also has eight texture-management units (TMUs). The GeForce GTX 285 has 10 texture-processing clusters (TPCs) with 24 individual streaming processors (SPs) (or cores) in each one. We will go over the major specifications. We're not going to delve too deep into the GT200 architecture, since we've done that already in our GeForce GTX 280 launch article, which you can check out here. Just like the G 210 and GT 220 before it, the new GeForce GT 240 is based on the same GT200 architecture that spawned the GeForce GTX 200-series.
