Extreme P55: Four LGA 1156 Motherboards Over $250
With better efficiency and more aggressive Intel Turbo Boost binning, LGA 1156-based processors could be the right choice for some high-end machines. We look at a few premium motherboards that make these builds possible. Do they best Intel’s X58 platform?
Nothing But The Best?
What defines a high-end system? Many proclaimed enthusiasts have expressed to us that the LGA 1156 platform simply wouldn’t be a suitable starting point for them, simply because it’s not designed to host a large number of high-bandwidth devices, such as graphics cards. And yet, most games don’t need more than a single Radeon HD 5970 to play at super-high settings. Moreover, not every high-end user wants to play games all day, and companies like EVGA and MSI have a workaround for those whose graphics desires exceed what Intel’s mid-range platform was really designed to do.
Setting aside the debate over P55′s suitability for hosting multiple graphics cards, a few key advantages that could put a shiny new LGA 1156-based processor into the hands of a high-end user include higher efficiency, higher stock performance via improved Intel Turbo Boost ratios, better overclocking, and reduced heat output for those who desire a quiet workstation build (there’s a reason Intel came to market with its Xeon 3400-series CPUs, after all).
Today’s contenders for P55 supremacy run the gamut from a $250 gamer’s board with advanced overclocking features to a $280 premium model with all the latest interfaces and a $340 product that supports a nearly insane number of up to six graphics cards. Our next page details the features that each motherboard boasts in an effort to overcome the mainstream market stigma associated with P55-based platforms.
AMD Launches 6 Core CPU-ready 890GX Mobo
This board is prepped for the hexacore AMD Phenom II X6.
AMD and its motherboard partners today released the AMD 890GX Chipset, integrated with the ATI Radeon HD 4290, and are designed to be compatible with the upcoming AMD Phenom II X6 six-core processor.
The AMD 890GX Chipset supports the SATA 3.0 6Gb/s hard drive interface and many AMD 890GX-based motherboards feature SuperSpeed USB 3.0 support.
We’ve got our hands on the Gigabyte GA-890GPA-UD3H, the Asus M4A89GTD Pro/USB3, and the MSI 890GXM-G65. After putting them through a barrage of tests, our reviews department found that AMD’s SB850 southbridge is probably the best reason to select an 890GX motherboard over the products it replaces thanks to the new integrated SATA 6Gb/s controller.AMD’s chipsets have long provided great features for the money, especially compared to high-end platforms like X48 and X58 from its chief rival, Intel. Everything between the mid-priced (still high-end) 790FX to its more commonplace integrated-graphics products can be attractive, depending on your usage model.
AMD’s multi-monitor advantage comes from the way it separates PCIe and GPU functions to deliver sixteen PCIe 2.0 lanes to graphics cards (up to two) without sacrificing integrated graphics functionality. Its Catalyst driver package controls both onboard and discrete Radeon graphics controllers simultaneously, seamlessly managing multiple desktop configurations. The three boards in today’s roundup have another advantage over those of our recent H55 comparison, in that those products didn’t support DVI dual-link mode for extra-large displays.
Another advantage today’s motherboards have over the Intel H55-based competition is the chipset’s additional PCIe 2.0 lanes, one of which supplies each of today’s motherboards with the same USB 3.0 controller at its full 5.0 Gb/s interface bandwidth. Intel’s chipset lanes run at half-speed, so that two lanes and a costly PCIe switch are required to reach the controller’s maximum throughput.
