Getting the new tech requires a new motherboard
With our skepticism of Thunderbolt officially blown away, weâre now ready to embrace the new I/O interface. But unless youâre one of the lucky few to have an older Asus board with support for the companyâs Thunderbolt add-in card, youâll 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
LGA2011 boards have always occupied the luxury side of town, whereas LGA1155 has been pretty blue collar. Not anymore. Asusâs new P8Z77-V Premium pretty much shatters the idea that LGA1155 boards are low rent.
The Asus P8Z77-V Premium comes fully loaded with features, including Wi-Fi antennas.
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 Intelâs âCactus Ridgeâ 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? Thereâs 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. Thereâs 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 âfreeâ 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 weâve reviewed. And unfortunately, not all the features make sense to us. The mSATA, for example, isnât 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.
Donât get us wrong, the P8Z77-V Premium is fully loaded, stable, and the fastest-booting Z77 board weâve tested yet (itâll 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.
Every feature known to man; incredibly fast boot; very advanced UEFI.
Pricey; mSATA drive doesnât make sense for a high-end build.

Gigabyte ZX77X-UP4 TH
Itâs 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 doesnât require you to smash the piggy. This is no more apparent than with Gigabyteâs ZX77X-UP4 TH. What the TH stands for we donât know for sure, but weâre guessing it has some relation to Thunderbolt, which the ZX77X-UP4 TH has in spades.
Itâs hard to believe you can get a board with not one, but two Thunderbolt ports for under $200.
The ZX77X-UP4 TH pretty much has all the modern must-have components, including both native Intel and discrete VIA USB 3.0 ports. Thereâs 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 isnât. The lack of extra SATA controllers, surface-mount power switches, extra SATA ports, and a POST LED affirms this boardâs pedestrian pedigree, but for the price difference, you could buy a CPU.
In performance, the board gave us interesting results. Itâs the first one weâve tested that has faster USB 3.0 performance than the Asus boards, but in overall graphics and system performance, the Gibabyte was slightly slower than the Premium board. To be fair, we did enable SSD caching on the Asus P8Z77-V Premium, but thatâs because the board comes with it. Like other Gigabyte boards, the ZX77X-UP4 TH turned out slower-than-expected performance in some graphics tests. Itâs not a huge disparity, but it shows up in the numbers. Because weâve seen it in three Gigabyte boards now, itâs 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 over time, but P.U.!
Despite the smell, itâs hard to argue with the bargain youâre 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 ainât arguing.
Dual Thunderbolt ports for under $200.
Could use more SATA ports; and smells like burnt toast covered with skunk ass.

Best scores are bolded. We used a Core i7-3770K, 8GB of DDR3/1866 set at DDR3/1600, a WD Raptor 150, 64-bit Windows 7 Professional, and a GeForce GTX 580 in all of our motherboards. SATA 6Gb/s speeds were measured with CrystalDiskMark 3.01 and an OWC Mercury Extreme SSD. USB 3.0 speeds were measured with CrystalDiskMark and a Patriot Wildfire SSD in a USB 3.0 enclosure using an Asmedia controller. 32GB compliance was measured with four 8GB DDR3 modules. The P8Z77-V Premium board was tested in SSD-caching mode.
