.18 µm Process Technology
GeForce2 GTS is produced in .18 micron technology, marking a 'shrink' from GeForce's 0.22 micron core. In the world of silicon 'shrinking' is always a huge blessing. It leads to faster switching transistors, thus increasing clock speed, it leads to smaller die sizes, thus reducing production costs, it leads to lower power dissipation, thus reducing the heat produced by the chip and lowering its power consumption. In case of GeForce2 GTS the amount of transistors has been increased by some 2 million to 25 million transistors. Those transistors aren't just there to waste space; they supply the additional features of GeForce2. The power consumption of GeForce2 GTS has halved from the bad 18 W eaten up by GeForce, which led to disaster on so many motherboards with weak power supplies. The power dissipation (which is the amount of power that the chip wastes to heat up our atmosphere) was reduced as well, but GeForce2 GTS still comes with a heat sink and fan of the same size as GeForce, which should give you some kind of idea about GeForece 2's heat production.
The new .18 micron die of GeForce2 is running at a 200 MHz clock, which can be seen as a significant improvement over the 120 MHz of GeForce. As a matter of fact it symbolizes the key factor for GeForce2's superior performance. Unfortunately advances in DDR-SDRAM technology haven't been as great. GeForce2 is using DDR-memory running at 166 MHz (practically 333 MHz) vs. the 150 MHz (practically 300 MHz) memory clock of its predecessor GeForce, since there's no faster memory available right now. This means a 66% increase in core clock, but a mere 10% increase in memory clock, translating in an at least 66% faster T&L and rendering engine that has to cope with an only 10% higher memory bandwidth of 5.3 GB/s. If GeForce used to have memory bandwidth problems already, GeForce2 GTS will have worse.
