Welcome to Valhalla: Inside the New 250GB Xbox 360 Slim
by Anand Lal Shimpi on June 18, 2010 1:59 AM ESTThe Motherboard
Two phillips screws hold the fan in place. You don’t need to remove them to remove the heatsink but I did anyway:
The single large heatsink is a lot heftier than what we'd seen in previous 360s, it doesn't feel quite as cheap or as insufficient. This time around it has to do double duty cooling both the CPU and the GPU.
At this point I can easily remove the motherboard and flip it over, revealing our old friend: the x-clamp.
Place your flathead screwdriver tip here, pointing away from the xclamp, and pry the clamp off at this point. Repeat for 1 - 2 more and the whole thing should come off easily.
Unlike previous Xbox 360s, the Valhalla x-clamp isn’t a pain to remove. In fact all I had to do was slide a small flathead screwdriver in each of the four slots in the clamp and push down to make the clamp pop out. I’ve marked the area on the photo above.
With the x-clamp removed the heatsink pulls off revealing Microsoft’s Xbox 360 CGPU covered with a heat spreader. The heat spreader is great for making sure no one cracks a core while working on these things.
The chip to the left of the CGPU is the 360’s South Bridge, responsible for the SATA and USB ports in the system. The chip is marked as an A0 stepping which is usually the first stepping to come back from the fab. This is probably a pretty tried and true design by now with no bugs to worry about at this point.
Xbox 360 South Bridge (top), 16MB SLC NAND (bottom)
The Hynix NAND on the motherboard is still 16MB in size. It is SLC NAND so it should last the lifetime of the Xbox as long as you don’t somehow mod it into a database server.
The third major ASIC on the motherboard is the HANA scaler/video encoder chip we’ve seen before on Jasper.
The motherboard now has two SATA ports directly on the board itself to support the new HDD tray.
I’ve also included a ton of close up shots of various parts of the motherboard in the dissection gallery for our friends at Xbox-Scene.
Have fun!

is still disappointing imho, at idle. Sure standby power is much lower, but that's just because it is required by law, so if you're surprised by this, don't be, EU regulation requires standby power below 1W nowadays (and less than 0.5W standby power in 2 years). There's no law though requiring to implement reasonable power management when devices are running, and unfortunately it shows. Apparently none of the current consoles have any power management worth speaking of, it's not required by law, it's not a selling argument, so the companies just don't bother at all. Seeing how power management actually takes an effort to get to work (usually riddled with bugs ranging from hardware clock gating issues up to software timers) this isn't terribly surprising, but maybe one day it will be a selling argument, since apparently at least in the pc world all cpus and gpus finally implement it...jigglywiggly - Saturday, June 19, 2010 - link
No you cannot connect any random dvd drive, they are tied to the motherboard.You can spoof them though.

#1. Why did Anandtech deliberately hide the fact that they used a very old Power supply to exaggerate the size differences between the newer Vallhalla Slim Kinetic 360 power supply? Most likely embargo from Microsoft??#2. Why no direct tests vs an newer Elite Jasper running a game from the HDD vs a new slim Kinetic running a game from the HDD. Why? because there is most likely no difference at all.
Way to ruin your rep AnAndtuch
So what embargos or restrictions did Microsoft put on you guys at Anantech?
Or are you guys now taking money in order to leave certain things out of your reviews??
We need to investigate Ananatechs behaviors, looks to me like they are no longer impartial or a credible source of reliable information.
This story goes deeper.

Are you fucking simple? What did you want anand to compare the new PSU to? A kitten? Comparing the new one to the old one is very comprehensive, shut your face.sdfdsfs - Saturday, June 19, 2010 - link
I'm guessing cost more than anything else, this thing has to be as cheap as possible in order to turn a profit.sdfdsfs - Saturday, June 19, 2010 - link

How can you keep a straight face talking about XBox 360 when 4 of 5 have died. I really can't understand why this isn't the biggest scandal in the tech world. This hardware has the worst track record in the history of electronics. I can see maybe buying a second one to replace the first, but a third, a fourth, a fifth! That's insanity!
