|

| Quote: | Description
After numerous reports about the exceptionally high Xbox 360 failure rate, Microsoft was forced to allocate 1 billion dollars to fix it.
Almost one year later, we have finally come to know the true story behind the historic RROD epidemic.
During the Design Automation Conference, Bryan Lewis, research vice president and chief analyst at Gartner, disclosed that it all begun with a single Microsoft's decision aiming to cut design costs for their Xbox 360 graphics chip.
According to Bryan Lewis, the epidemic happened because "Microsoft wanted to avoid an ASIC (application-specific integrated circuit) vendor", so they designed their own graphics chip and sent it directly to Taiwan Semiconductor Manufacturing for production.
Normally, semiconductor chips are designed on two stages. The first of them is the Schematic design where engineers draw a symbolic representation of the circuit. This should have been done by Microsoft. The second stage is PCB Layout design. In this stage, the abstract representation of the circuit is converted to real life Printed Circuit Board through a delicate and complex design process. Apparently, Microsoft decided to design its own PBC, but failed and ended up with an RROD epidemic.
"Had Microsoft left the graphics processor design to an ASIC vendor in the first place, would they have been able to avoid this problem?", Lewis asked before answering himself. "Probably. The ASIC vendor could have been able to design a graphics processor that dissipates much less power."
To fix the problem, Microsoft went back to an unnamed ASIC vendor based in the United States and redesigned the chip, Lewis added. (rumors have it that the ASIC vendor is most likely the former ATI, now part of AMD.)
Moral of the story: by going cheap and trying to save tens of millions of dollars in ASIC design costs, Microsoft ended up paying more than $1 billion for its Xbox 360 recall. |

It wouldn't surprise me though
Big corporations and cheap labor have been a perfect match for a long time and i don't think that M$ is any different.

Theres no proof to the contrary either. Sounds feasible enough to me. I mean after the first xbox Microsoft had no doubt paid shitloads of money to Nvidia (was it?) to design their graphics chip. for the next gen console why not cut out the middle man too maximise your profits?.
What Reg67 said pretty much summed it up for me.
Otherwise you could just say that the early 360s' had a shitty build quality.

xbox 360 comes with Ati Xenos 500mhz gpu
the only thing they changed in late builds is cpu, mobo and cooling
nVidia gpu was only in xbox 1, nVidia NV2A 233 MHz

Yep thats the one Mortibus, the Xenos chip. I remember I bought the Ati graphic card (can't even remember which one it was now.. x800xt or x1900) for my PC around that time when the 360 first came out as they were pretty much of a similar spec.

Falcon has a different CPU, mobo and a slightly different cooling like Mortibus said. The GPU should be the same as Zephyr. The rumoured new chipset could have the 65nm GPU.

well most of the problems seem to be caused by the tiny heatsink on the gpu, and the large amount of heat the gpu puts out. will probably be solved by a die shrink and the redesign of the gpu heatsink.
The night is dark and the road is long. Come on dead men, return to your homes.

Lmao wow I was trying to figure out why Microsoft would involve rats in their development to begin with. Was confused there for a sec
