Equipped with the same high-end Intel network controller, the same ASMedia add-in SATA 6Gb/s controller, the same USB 3.0 hub, and a slightly cheaper audio codec, Asus’ Z87-Plus needs to do something extremely well in order to overcome its price premium compared to ASRock’s competing Z87 Extreme4. Asus has a long list of features that it says add more value than any other vendor, and the USB BIOS Flashback feature is one strong example.
The BIOS Flashback IC resembles an SoC (system on a chip) for its specific function, allowing users to update the firmware with nothing more than a USB flash drive and power supply. Incompatible parts play no role here, since you don't even need to have a processor installed. This is particularly brilliant when a customer purchases an older motherboard that was sitting on a store shelf for months and an unsupported CPU at the same time. Of course, Haswell just came out, so you wouldn't actually need this value-add until later, when Intel refreshes its platform.
Asus skips the I/O panel-based eSATA connector that ASRock shares with an internal port, and instead routes that interface to a connection accessible internally. The Z87-Plus also skips over the Z87 Extreme4's second internal USB 3.0 connector in favor of exposing six ports on the rear I/O panel. Your own preferences should dictate the configuration that works best.
Your needs will also determine the best slot arrangement. Asus splits the CPU’s 16 PCI Express 3.0-capable lanes across two slots, wiring its third slot to slower second-gen pathways from the PCH. While that means the third slot has far less bandwidth, it also won’t steal lanes away from the two graphics cards you might also install. Frankly, Asus' implementation makes more sense for most enthusiasts. But it incurs another drawback: the bottom slot is only wired up to two of those slower PCI Express 2.0 lanes. That means the third physical x16 is almost as ill-suited to a high-end RAID card as it is to three-way CrossFire. Being better for most users is an admission that most folks (particularly in the mainstream space) aren't using intricate storage arrays or three-card graphics setups.
The Z87-Plus doesn't have a POST code display or a bunch of motherboard-based buttons. But it does come equipped with switches. Among them are EPU and TPU mode selectors for automatic under- and overclocking, depending on your power or performance needs. The buttons you do see on-board correspond to power, BIOS Flashback, DirectKey for direct-to-UEFI booting (particularly useful in Windows 8), and MemOK for DRAM-underclocking to assist diagnostics.
We didn’t find any serious layout concerns on the Z87-Plus. Asus moves its front-panel audio connector around an inch forward from its typical location to help builders using cases with slightly short cables, and instead puts a special header for its ThunderboltEX card in the bottom-rear corner.

The Z87-Plus installation kit includes only four SATA cables, though a single SLI bridge and cable-bunching front-panel header extenders are also useful.

1- the x8x4x4 PCIe controller is a CPU feature in all i5 and i7. All the z*7 chipset does is unlock the CPU feature
2- same goes for multipliers on K-chips: CPU feature locked out by non-z*7 chipsets
3- SATA-6G ports do not really cost Intel any thing extra to put on-chip (little more than a PLL tweak to lock on faster signals), which makes it somewhat of a shame they aren't fully standard
4- USB3 ports do not cost Intel all that much extra either - maybe an extra square millimeter on silicon to upgrade all remaining USB2 ports to USB3
5- the DMI bus can only manage ~20Gbps so it will bottleneck if you attempt to use even 1/5th the total the connectivity available on z87
More connectivity, yes. But DMI lacks the muscle to actually stress that extra IO. As such, it is little more than a glorified SATA port replicator and USB hub.
I almost exclusively use Intel CPUs but it still annoys me how Intel charges extra for trivial things or unlock stuff they arbitrarily locked out just because they can.

In other words, they might be charging for stuff that should be free or should have been included all the way back in the Z68, but past omission doesn't negate current usefullness.
The market is flooded with tons of these Z87 motherboards and it can be very overwhelming researching them. So, hopefully we'll see a few more Z87 reviews from you guys, soon.
Would also like to see some powerful i7 builds built around more energy efficient components. That would be very interesting. Hint.
Rather surprised that Biostar had such a good board. Maybe it's time to start considering those boards for future builds.
It is great to see a round-up of the mainstream boards, though, so thanks!
Most users don't have enough such devices to fill every port in the first place (how many people need more than two upper-tier SSDs?) but those who might actually "need" and use 6xSATA-6G would be people wanting to do things like RAID0/1/5 with 3-6x SSDs. At 6x SSDs, we would be looking at ~25Gbps peak not counting GbE, USB3 or PCIe devices on the 8x 2.0 lanes.
Still does not change the fact that the only reason why Intel gets away with charging $10-15 extra for less than $1 worth of features while the DMI bus lacks the bandwidth to properly support them for people who may actually intend to use them is because they have a practical monopoly which allows them to arbitrarily fragment the market so they can artificially inflate prices.
The main reason most people go with z?7 is the overclock unlock for K-chips. That itself is the biggest joke since it is a completely artificial limitation Intel engineered into their products to enforce co-upselling. As shown with the h87 slip-up, the h87 is perfectly capable of managing multipliers on Haswell K-chips when the K-chip lacks the microcode to enforce the z87 unlock "requirement."
I don't bother with overclocking so this does not affect me... but it still annoys me on the basis of principles and general dislike for hair-splitting for profit.
I'm about to build a new gaming box, and I'll consider the 'winners' in the article when I'm shopping. While price is not a big driver for me, I'll see if ASRock stays true.
Instead of just cheap, you mean?
ASUS - 16
ASRock - 10
Gigabyte - 11
MSI - 8
ECS - 3
Biostar - 2
How in the heck does marketing sort out product definition for 16 models, all for the same form factor?
ANYWAY, your choice
Spend a lot for a single issue fix
Spend a lot more for a new layout with superior everything and future proof for next gen CPUs.
Spend nothing, stop whining and deal with it.
Thanks
