iSuppli's report, issued Monday, says that the current PS3 model contains 2,820 individual parts, including Nvidia's Reality Synthesizer, IBM's Cell Broadband Engine, and Toshiba's I/O controller, which are now made using 65-nanometer process technology, compared to 90-nanometer technology formally employed in the previous iteration. That has drastically reduced the PS3's power supply cost by 30 percent from $30.75 to $21.50.

Kionix's three-axis accelerometer in the PS3 controller has replaced the Hokuriku Electronic Industry Co. part, saving Sony an estimated $1.45 per unit.

But perhaps the most important cost savings is in the console's vaunted Cell processor from IBM. According to iSuppli, the latest PS3 includes a new version of IBM's Cell Broadband Engine, which is priced at $46.46 -- 28 percent lower than its original cost in the first-generation hardware. A new version of Nvidia's Reality Synthesizer, the console's GPU, at $58.01 per unit is now priced 30 percent lower than it was in the first generation.

Altogether, Sony's second-generation PS3 features a 35 percent total cost reduction from the first-generation model. In dollars and cents, today's PS3 costs Sony about $448.73 to produce, compared to the old model's $690.23 price tag. That said, the lower cost doesn't include software, box contents, and royalty expenses.
