P55 Motherboard Round-up: Asus, EVGA, GB, Intel, MSI

Gigabyte makes a copious amount of P55 models and actually sent us three for this round up. The first one we'll be looking at is the UD4P. At $180, this board isn't cheap but it is still relatively affordable for consumers looking to start a new Core i5 or Core i7 build. Something to note on the design of this particular sample is that it slightly differs from the retail model. While similar in many ways, the southbridge heatsink is missing the Gigabyte logo and several of the expansion slots sport various colors. Retail offerings use only white and baby blue slots. If you're unfamiliar with Gigabyte motherboards, their trademark feature is called Ultra Durable 3. This design uses 2 ounces of copper for both the power and ground layers of the PCB, and promises to lower system temperature by dissipating heat from critical areas of the board more efficiently. Gigabyte also claims this feature lowers impedance up to 50%, improves signal quality, lowers EMI, and improves overclocking. The company also makes use of solid Japanese capacitors, lower Rds MOSFETs, and ferrite core chokes. All of which help with long term reliability for consumers. This board presents a well designed layout that is common for Gigabyte products.

A look at Asus' P7P55D and Gigabyte's GA-P55-UD4P motherboards

With a street price hovering around $250, the Gigabyte GA-P55-UD6 we looked at during our P55 launch coverage is decidedly not a mid-range motherboard. The $170 GA-P55-UD4P is certainly more reasonably priced, even if it does run $20 more than Asus' P7P55D. Fortunately, the extra $20 hasn't been frittered away on gaudy lighting effects, questionable accessories, or other wasteful avenues. Instead, Gigabyte has beefed up the UD4P's hardware, which ultimately makes for a more versatile board. Like the P7P55D, however, the board itself isn't quite as fancy as more indulgent models. There are only four board layers, down from eight on the UD6. Gigabyte still squeezes in two-ounce copper layers, though. It also litters the board with high-quality electrical components, such as ferrite-core chokes, low RDS(on) MOSFETs, and solid-state capacitors. Just looking at the UD4P, you might think the board had traditional north and south bridge chipset components. The P55 PCH is actually in the lower right-hand corner, as we just saw with the P7P55D. What looks like a north bridge cooler is acting as an additional heatsink for the board's power regulation circuitry.
