Since quite some time ASUS has been
equipping its boards with digital power designs. Using the right
software it is not only possible to adjust voltages while being in
Windows one can now also control impedances.
ASUS ships the P8Z77-V
Pro/Thunderbolt with native Thunderbolt support. Utilizing the x4 lanes
of PCI Express together with the iGPU integrated DisplayPort output, the
P8Z77-V Pro/Thunderbolt is capable of delivering a simultaneous
bi-directional throughput of 10 Gbps via this Thunderbolt port. This port is also
capable of displaying video content with up to 2560 x 1600 resolution.
Fruthermore it is also possible to realize a triple display solution
using only the iGPU.
the P8Z77-V Pro/Thunderbolt with Wi-Fi support via a physical layer (PHY) that is being connected
to the board. An antenna is also bundled to increase wireless range.
If you activate the EPU, this chip is going to monitor all
the different voltages and clock speeds and automatically sets them
guarantee an energy efficient operation of your system.
As soon as one activates the TPU this chips monitors all
voltages and clock speeds using the according software. The
difference to the EPU is that TPU will provide as much performance as
possible. Therefore it can increase clock speeds and voltages.
