Roundup: Five P55 mainboards

Written by Eliot Kucharik

Review: From €88 to €175


This article is also available in German.


We had more than two months to play around with our P55 boards. Generally speaking it's good to wait always before buying new stuff, because after some time you can expect mature boards that will not cause much troubles.

We tested two boards in the sub €100 market, one in the sub €130 market and two which we consider high-end, as they cost upwards of €160. While the boards perform around the same level they only differentiate by features and layout.

A fast recap of the P55: This is now called Platform Controller Hub, which in fact is a Southbridge. To avoid competition to the X58 platform all eight PCIe 2.0 x1 lanes are crippled to half speed, so you get PCIe 2.0 x0.5. This causes all sorts of problems for vendors who want to integrate USB 3.0 and SATA 6Gbps, at least there is no hard drive which can fully utilize SATA 6Gbps, but for SSDs this feature could be interesting.

We think the LGA 1366 offerings have no merit, besides one memory channel more, which gave us the odd 3GB, 6GB and 12GB memory configurations, the LGA 1156 offers faster speed at same clock due to higher turbo modes. This will not change as long Intel comes not out with it's 32nm offerings. Besides that, Hyperthreading doesn't work most of the time, and only a few applications can benefit from the feature. For Gamers and highly optimized applications it may even slow down the performance.

Also the lower power consumption despite the included northbridge of the i5 line makes it the perfect choice for most users. Compared to the X58 platform we noticed all BIOSes have changed the C-States setting to enabled, whereas the X58 platform has that option disabled. With an i5-750 that costs only 0.5% performance, but saves a lot in idle and even shaves off some wattage under load.
