Xenon (V1)

The original Xbox 360 configuration used in the initial Premium and Core machines released in the end of November 2005.
These are also known as the RRoD (Red Ring of Death) machines because the GPU chip warps away from the motherboard because of excessive heat.

• Consoles : Core, Pro/premium 20gb
• 90 nm IBM CPU
• 90 nm ATI GPU and 90nm on-chip eDRAM
• Low profile GPU cooler
• Standard CPU cooler
• 203 Watt output power supply (16.5 A)
• Shipping with Hitachi46-78, Samsung ms25or ms28, Benq DVD-Drive can also come with lite-on if it was refurbished.
• Highly unlikely to have glue around the CPU but it IS possible.

Zephyr (V2)

Zephyr was the first revision with HDMI connector
It was introduced with the Xbox 360 Elite in May 2007.
In July 2007 Xbox 360 Premium machines began appearing with the Zephyr motherboard.

• Consoles : arcade, Pro/premium 20gb, Elite 120gb and Halo 3 Console

Falcon (V3)

All Xbox 360 Premium machines and Arcade machines made in August 2007 introduced the new 65 nm CPU accompanied with a new cooler and still 90 nm GPU with the Zephyr cooler.
The motherboard is based on Zephyr and requires fewer components (some capacitors and coils removed) for the new 65 nm CPU, resulting in lower costs.

• Consoles : arcade, Pro/premium 20gb & 60gb, Elite 120gb
• 65nm IBM CPU
• 90nm ATI GPU
• 80nm on-chip eDRAM.

• New CPU Heat sink + the GPU heat sink with heat pipe
• Fewer voltage regulators, capacitors and inductors
• Bigger and enhanced CPU cooler
• Ram removed from bottom of mainboard on later models
• 3 pin fan connector
• Shipping with Hitachi 79, BenQ and new LiteOn 7XXX series DVD-Drive

Opus (V3.1)

This is an intermediate motherboard with 65 nm CPU and 90 nm GPU, new coolers, but no HDMI. It will be used in Xenon chassis for repairs and RRoD affected machines.
Started to appear end of July 2008 in machines coming back from repair. Is just a falcon without with a custom Av port so that it fits into a xenon chassis and case

• Consoles : core, Pro/premium 20gb
• Falcon based board
• 65 nm IBM CPU
• 90nm ATI GPU with 80nm on-chip eDRAM

• 3 pin fan connector
• Shipping with Hitachi, Samsung, Benq and LiteOn 7XXX DVD-Drive
• Opus only available from xenon being repaired by MS.
• Very Rare

Jasper (V4)

Jasper introduced the 65 nm GPU to reduce power usage and cost further.
The new power supply is rated for 150 Watt, down from 175 Watt on the Falcon. The Amperage on the 12V rail is down to 12.1A (12.1A x 12V = 145.2W).

The on-board flash has also increased to allow the new NXE (New Xbox Experience) dashboard update to reside internally, instead of requiring a memory unit or the hard drive.

• Consoles: arcade 256mb & 512mb, Pro/premium 60gb, Elite 120gb & 250 and Resident Evil 5 console
• 65 nm IBM CPU
• 65 nm ATI GPU with 80 nm on-chip eDRAM
• 150 Watt PSU (12V rated for 12.1A, new connector)
• Arcade Edition Larger Flash 256 MB or 512 MB Hynix HY27UF082G2B on-board flash, up from 16 MB HY27US08281A flash, to accommodate the NXE update.

• Ram removed from bottom of mainboard
• New style CPU Heat sink + the GPU heat sink with heat pipe
• 3 pin fan connector.
• New Warranty Sticker.
