New HDMI Xbox 360s are still Zephyr, not Falcon

When it was discovered that standard Xbox 360 Premium packages were coming equipped with HDMI output, the first question on many gamers’ minds is if this new box was indeed the quiet introduction to the much awaited and anticipated shrink to 65nm chips.

One brave soul on hardcore gaming forum NeoGAF decided to help answer that question for everyone and cracked open his new console for educational purposes. It appears those waiting for the 65nm die shrink will have to wait some time longer, as examination of the innards of the Premium box with HDMI reveals the identical “Zephyr” motherboard layout as originally discovered in the Xbox 360 Elite console.

The main differences between the previous Xbox 360 motherboard and the new “Zephyr” are mainly in power supply. As detailed in an earlier article with regards to a dissection of the Xbox 360 Elite, the new motherboard makes use of smaller capacitors arranged in slightly different arrangements. Microsoft has also reduced the amount of MOSFETs installed in the power supply section of the PCB. There are also fewer resistors located above the CPU as well. However, despite the power changes, the die size remains the same as with the HDMI-less Xbox 360.

One notable addition to the new Xbox 360 Premium console is the inclusion of added cooling measures not found in previous iterations of the console. A new heatsink with a heatpipe that leads to a secondary “daughter” heatsink helps to further cool the GPU.

For gamers waiting for an even cooler running box, the next step will have to wait until the arrival of “Falcon,” – the codename for the 65nm Xbox 360 GPU and CPU. Microsoft has not officially confirmed the production of its new, smaller, cooler chips, but industry experts are expecting “Falcon” to land sometime this fall.

very true, i never thought about the existing DVD drive cost.
I personally like the HD-DVD addon, neither my TV nor projector has HDMI, and i can not think of another High Def player offhand that will play at full resolution over component. Although TrueHD,LPCM7.1 capabilities are crippled, DTS works just fine for me.

HDCP is only over HDMI/DVI and is already 'implemented', do you mean AACS/ICT. High def player makers are not suppose to allow the transfer over component, but there is nothing in HDCP blocking it, its within the AACS encryption where the ICT fullrez flag is located, and no movie company plans on turning it on any time soon. Also if MS allows it, and decrypts the data within the 360, there will be no problem. People decrypt the hdcp signal all the time when using their 360 addon on their PC, it can be done, and if anyone can to do it, its MS

You won't see that though, for a very long time. If ever.
They would have to win the format war before they even contemplated such a move. And win it undeniably huge.

Probably won't ever happen. But if it does, a standalone HD-DVD player will cost $100 by that time.
Not much to worry about.
