A new report has revealed the updated internal codenames for Microsofts and Sonys next-generation consoles, the Xbox 720 and PlayStation 4. The report also offers new details on the chips that both consoles will use.
SemiAcurate is reporting (via internal sources) that Microsoft is now referring to the next Xbox console as Kryptos instead of the more widely known Durango name that has appeared in several previous reports. The sites sources also claim that Microsofts next console will use an AMD chip codenamed Oban, however production issues have caused component quality to be painfully low, which could lead to delays.
Wii U launch: Software and battery life woes, and more hardware details emerge

This is it, ladies and gentlemen: Following this weekends release of Nintendos Wii U console, the eighth generation of video game consoles is finally here. Its been a long time coming seven years, to be exact; the longest generational gap ever in the history of games consoles but hopefully the wait will be worth it. With the Wii U selling out across the US, and games retailers seeing record numbers of pre-orders, early reports are generally good, with a handful of negative caveats that mostly involve the Wii Us tablet Gamepad and a beefy, hours-long firmware update.
With video game consoles, their exact hardware specifications are always a bit mystical. Prior to their actual launch, console makers rarely tell us more than the absolute minimum, such as it will be backwards compatible or it will be much faster than its predecessor. As soon as the console goes on sale, though, we can finally tear the thing open and find out whats actually under the hood which is exactly what Anandtech did.
We already knew that Nintendo had opted for an AMD GPU/IBM CPU multi-chip model (MCM) in the Wii U, but we now have the exact die sizes: 5.2mm x 6.3mm (32.76mm2) for the CPU, and 12.2mm x 12.7mm (156.21mm2) for the GPU. There is also a third, absolutely tiny (1.79mm x 1.48mm) die on the MCM, which Anandtech speculates is off-chip memory.
As for the exact specifications of the CPU and GPU, its still a bit of a guessing game. From a previous teardown by Nintendo, we know that the Radeon-derived GPU has some on-chip memory, no doubt increasing the die size considerably. If we start with a 104mm2 Redwood core found in the Radeon HD 5670, then pile on some megs of eDRAM, we approach the 156.21mm2 die size of the Wii Us GPU. This assumes that a 40nm process is being used (and considering the relative cost/scarcity of 28nm production, its almost certainly 40nm). A Radeon HD 5670 with on-die memory would be a fairly beastly GPU, far outstripping the Xbox 360 and PlayStation 3 but hey, those consoles are seven years old now.
On the other hand, the tiny, multi-core Power-based CPU isnt going to win any performance prizes. Beyond the fact that its manufactured on IBMs 45nm SOI process and has on-die eDRAM, we know very little about the CPUs exact specifications. Due to the fact that the Wii U is backwards compatible with the Wii (i.e. they have the same instruction set architecture (ISA)), the persistent rumor is that the Wii U simply takes the Wiis Broadway core, and multiplies it by three. Throw in a few tweaks and a few process node improvements (from 90nm down to 45), and the Wii U CPU should be fairly competent. Ultimately, though, as we all know, the CPU clock speed and core count are ultimately just footnotes: For the Wii Us new and shiny 1080p HD output, that beefy GPU is far more important.
Rounding out the hardware spec, Wii U teardowns have revealed that theres a Samsung NAND flash chip for user storage (32GB or 8GB), a Toshiba NAND chip for non-user storage, and 2GB of Hynix DDR3-1600 RAM on a 16-bit interface surrounding the MCM, providing peak memory bandwidth of 12.8GB/s. This is twice as fast as the Wii, but for 2012 its pretty slow though, with the on-die eDRAM, the DDR3 bus shouldnt see too much usage.
By all accounts, the Wii U Gamepad is the centerpiece of Nintendos new console and yet, curiously, every tech publisher (including ET) has failed to report on a massively vital caveat: battery life. It turns out that the Wii U Gamepad, with its large, 6.2-inch resistive touchscreen display, only has a 5.6 watt-hour battery (1500mAh @ 3.7V). Early reports suggest that the Gamepad only lasts 3-4 hours between charges okay for casual gameplay, but it may put a serious dent in prolonged gaming sessions if you have to stop and recharge. The good news is that the battery is replaceable and were sure its only a matter of weeks until larger, third-party batteries are made available.
