Chip process evolution is a usual thing in a console’s lifecycle, but rarely has it been as important as in the case of the Xbox 360.
Known for its relatively hardware fragility, the original design of the Xbox 360 would frequently fall to the “Red Ring of Death” failure, which Microsoft terms as the three flashing red lights. While improvements in cooling and a CPU die shrink to 65nm in the Falcon revision have surely improved the situation, the problematic GPU still sits with its 90nm process.
The 65nm drop for the GPU in the Xbox 360 revision codenamed Jasper isn’t expected until August, a time frame backed up by a report from CENS. Microsoft has contracted Taiwan Semiconductor Manufacturing Co. (TSMC), Advanced Semiconductor Engineering Inc. (ASE) and Nanya PCB Corp. to build the chips that will ship with the Jasper consoles later this summer.
TSMC will produce the 65nm chips, ASE will package and test them, and Nanya will supply the flip-chip packaging substrates. Microsoft has supposedly booked a production capacity at TSMC estimated to be at around 10,000 300mm wafers.
Inventory of the existing Falcon chips are reportedly depleted, paving the way for the transition to Jasper. The next step for the Xbox 360 console is dubbed “Valhalla,” which will integrate both the GPU and CPU in a single package as a cost-cutting measure, isn’t expected until a year after Jasper.

quote: This isn't rocket science, it should have been picked up during testing.
quote: What is testing meant to do if not simulate the life of a console under many conditions?? Its actually, believe it or not, meant to be able to simulate wear and tear, safety, temperature and likely failure rate.
quote: The fact is quality control across ALL aspects of consumer products has really gone down hill over the past few decades. Quit trying to crucify MS over something thats become almost acceptable in the electronics industry. Everyone subcontracts for parts to the lowest bider these days
