Thunderbolt Arrives!

Getting the new tech requires a new motherboard

With our skepticism of Thunderbolt officially blown away (see last month’s Head to Head) we’re now ready to embrace the new I/O interface. But unless you’re one of the lucky few to have an older Asus board with support for the company’s Thunderbolt add-in card, you’ll need to buy a new motherboard to enjoy Tbolt goodness. Luckily, Thunderbolt boards have arrived. To gauge the choices, we gathered up both the priciest and cheapest Tbolt boards we could find and set at them.

ASUS P8Z77-V Premium

Price: $450

LGA2011 boards have always occupied the luxury side of town, whereas LGA1155 has been pretty blue collar. Not anymore. Asus’s new P8Z77-V Premium pretty much shatters the idea that LGA1155 boards are low rent.

How swanky is it? This Z77 board is brimming with every bell, whistle, and horn available. Obviously, Thunderbolt is here, in the form of a single Thunderbolt port using Intel’s “Cactus Ridge” DSL3310 second-gen Tbolt controller. Asus also equips the board with a PLX8747 PCIe 3.0 switch chip, so the board is able to run up to four GPUs. Boards without a bridge chip are normally constrained to two GPUs, and some boards switch off com­ponents too.

Want more? There’s also the excel­lent Asus fan controls, a Wi-Fi and Blue­tooth module, a secondary Marvell SATA 6Gb/s with four ports, and a 32GB Lite-On SSD in the mSATA slot, in addition to the two Gigabit ports running Intel silicon. There’s so much hardware jammed onto this board, it takes an afternoon just to go through the UEFI settings.

Performance of the board is quite good, especially with the "free" mSATA SSD used for caching (which we did for our testing).

So how much does all this hardware cost? A lot. At $450, the P8Z77-V Premium is the most expensive Z77 board we’ve re­viewed. And unfortunately, not all the fea­tures make sense to us. The mSATA, for example, isn’t useful for anything beyond caching due to its size. But will someone who runs a 4x GPU setup and Thunderbolt really be running a hard disk as his or her primary boot device?

For the most part, you have to have particular needs to want the P8Z77-V Premium. Obviously, just wanting the most tricked-out Z77 board on the market is one need. The other is more practical: You need to run more than three GPUs and you must have Thunderbolt. Frankly, without those specific needs, we think it would be more fiscally prudent to buy a non-Premium version of the P8Z77-V and add the optional Thunderbolt card.

Don’t get us wrong, the P8Z77-V Pre­mium is fully loaded, stable, and the fastest-booting Z77 board we’ve tested yet (it’ll go from cold to OS in 17 seconds in Windows 8) but most folks will likely find it just too much motherboard for too much money.

Gigabyte Z77X-UP4 TH


Ratings: 8

Price: $190



Description: It’s hard to believe you can get a board with not one, but two Thunderbolt ports for under $200.

It’s hard to believe you can get a board with not one, but two Thunderbolt ports for under $200.

It’s commonly understood that if you can run Thunderbolt, you probably also snack on Beluga caviar, wear a Patek Philippe watch, and vacation in a country only rich people know about: Grenyarnia.

Not so, actually. Thunderbolt appar­ently doesn’t require you to smash the piggy. This is no more apparent than with Gigabyte’s Z77X-UP4 TH. What the TH stands for we don’t know for sure, but we’re guessing it has some relation to Thunderbolt, which the Z77X-UP4 TH has in spades.

The Z77X-UP4 TH pretty much has all the modern must-have components, in­cluding both native Intel and discrete VIA USB 3.0 ports. There’s also SLI/CrossFireX, an mSATA slot, and not one, but two Thunderbolt ports


The fact that Gigabyte can jam all this into a board that streets for $190 is astounding. Lest you think the board is the equal of the P8Z77-V Premium, it isn’t. The lack of extra SATA controllers, surface-mount power switches, extra SATA ports, and a POST LED affirms this board’s pedestrian pedigree, but for the price difference, you could buy a CPU.

In performance, the board gave us inter­esting results. It’s the first one we’ve tested that has faster USB 3.0 performance than the Asus boards, but in overall graphics and system performance, the Gigabyte was slightly slower than the Premium board. To be fair, we did enable SSD caching on the Asus P8Z77-V Premium, but that’s be­cause the board comes with it. Like other Gigabyte boards, the Z77X-UP4 TH turned out slower-than-expected performance in some graphics tests. It’s not a huge dispar­ity. but it shows up in the numbers. Because we’ve seen it in three Gigabyte boards now, it’s likely some driver-related issue.

Another thing we should note is that our review board smelled like an iPhone crawled into the ass of a laptop and died there. The heavy electronic stink was so overwhelming, we were ready to bury our face in a skunk to get rid of the odor. The smell diminished overtime, but P.U.!

Despite the smell, it’s hard to argue with the bargain you’re getting here. The board lets you run multicard setups, packs two Thunderbolt ports (which were tested to within a few percentage points of the Asus P8Z77-V Premium), and even seems to have improved the USB 3.0 per­formance markedly. Yes, it could use a couple more SATA ports and a good airing out, but for the money, we ain’t arguing.
