The Asus P4G8X Deluxe Motherboard
Intel E7205 - Granite Bay Infused Horsepower

The first Granite Bay (Intel E7205 chipset) motherboard to grace the HotHardware Laboratories not long ago, was MSI's GNB Max.  This board, supports Dual Channel DDR and AGP8X, as well as a host of other features, for the Pentium 4 platform.  However, this board, as well as a few others we have seen specifications for, seems to be more targeted at the High End Workstation crowd, rather than the enthusiast or "Overclockers" out there.  In fact, Intel's strategy with this new chipset for the Pentium 4, is also to target this space as well.  Intel's follow-on chipset, code named "Springdale", so we've been told by a few sources, is going to be much more suited toward the enthusiast crowd.  We'll get back to more detail on this later but the point is, Granite Bay boards are coming into focus now and they are not completely focused on the types of end users, that make up the Elite HotHardware - Custom PC building clientele.

Now, having said this, Asus Computer is well known for bucking the trend and also for not following the standard "reference design" model for their Motherboard product lines.  It seems as though, good bad or indifferent, Asus always puts their own personal spin on their products and for the most part, they cater to you and me, the Custom Built PC Enthusiast.  As one might imagine, their first incarnation of a Granite Bay offering is cut from the same cloth.  The real question is, "is it ready for prime-time in the enthusiast market segment"?  We'll try to cover all the salient points and performance characteristics of the Asus P4G8X and let you be the judge.

The board configuration itself is quite similar to the MSI Granite Bay board we reviewed here not long ago, with a few subtle differences.  Asus uses a Broadcom Gigabit  Ethernet controller, versus the Intel controller MSI used.  In addition, MSI's board uses a C-Media 6 Channel Audio solution, which we prefer rather than the Realtek CODEC that Asus used on the P4G8X here.  Finally, the Asus folks chose to go with a Silicon Image SATA chipset, versus the Promise Controller MSI went with.  Once again, we like the route MSI went, with Promise for the SATA solution, since that seems to be a bit more mature and has a better RAID BIOS, in our opinion.  We will cover this later in the BIOS setup however.



Intel's E7205 chipset, as you can see, provides 4.3GB/sec of memory bandwidth to the Pentium 4's 533MHz system bus.  The chipset supports up to 4GB of RAM, so server implementations can easily be supported with the cost effectiveness that DDR DRAM offers.  In addition, AGP8X support is provided and we are happy to report that our Radeon 9700 Pro, that we used for testing, worked flawlessly throughout our benchmark runs.

The P4G8X provides 4 USB ports on the back plate, as well as two serial, Ethernet, Sound, Mouse and Keyboard jacks.  Included with every board is a custom back finish plate for installation into your chassis of choice.  In the middle shot, you'll see the power connectors on the P4G8X, neatly arranged at the edge of the board.  This is a great location for obstruction free ATX Power Cable stringing. 

Additionally, Asus provides their standard Auxilary Power connector, for alternative use versus the 4 pin ATX12V power connector.  This is a really nice feature, since you can then use any standard ATX power supply (we recommend at least 300W) and not have to worry about having the P4 compliant ATX12V connectors, since you can simply plug in a 4 pin drive power connector in this socket.  Finally, Asus has installed a stout heat sink on the E7205 Northbridge.  This provides adequate cooling but we would have preferred an active solution here with an integrated fan.
