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.

Ah grammar, how I wish I had known thee better.

What's funny is this article is based on ... a forum post. Lol.

Sometimes forum posts can be very very informative. Just have to wade through all the bullsheeyat. Inside sources love to post on forums because of the anonymity.
