Intel Z97 Express: Five Enthusiast Motherboards, $120 To $160

Tom’s Hardware readers set a higher bar for enthusiast-class motherboards, demanding overclocking capabilities and more robust feature sets. Priced from $120 to $160, we welcome the first five Z97 motherboards to our enhanced definition of mainstream!

Power, Heat, And Efficiency

All manufacturers make great claims about voltage regulator efficiency, but ASRock and Asus bolster those claims at full load in the Z97 Extreme4 and Z97-A. Then again, a slight decrease in core voltage could produce similar results without causing a system crash.

Those reductions in power consumption are also seen in lower CPU temperatures, so lower full-load voltage does appear the most likely reason for saved energy. The question is, does this hurt overclocking?

Anyone really keen on overall performance charts can find one in this article’s image gallery. But the overall performance difference comes down to less than half of one percent. That means power savings translate almost directly into an efficiency improvement.

The Z79 Extreme4 wins the efficiency race, followed by the Z97-A.

    The table detailing the motherboard features on page 1 ... Is it just me, or is the text a bit small?

    I'd like to see a review on the significance of the 'killer' NICs... I highly doubt they have any difference besides branding.

    so intel it seems doesn't have much faith in their own thunderbolt considering there is no thunderbolt ports on this new chipset!

    The Asrock one is better. Not everyone will be using XSplit, and as tradesman1 (a moderator on this site) said "I myself won't touch MSI mobos due to the poor QC".

    READ PAGE ONE to find out why this chipset has the same features as the previous chipset.

    Good review :) I am looking forward to the best price:features motherboard review though (extreme6). I have a quick question crashman: Do asrock still use Capxxon caps (or just crappy caps in general). I would like to know the company of the caps if possible, once again, thank you :)

    I wish I knew. It appears that they get their caps custom-wrapped to get the gold color, and that the custom wrapping only has specifications (no branding).

    Not exactly the most comprehensive review, but here is Asus' take on NICs: http://rog.asus.com/312772014/labels/guides/tried-and-tested-why-intel-ethernet-is-still-better-for-gaming/

    Of course, they're testing throughput, and latency is what is generally considered to matter.
