ASRock X99 WS-E/10G Review

X99 Chipset Features

First and foremost, Intel's latest chipset is aimed at the home 'power' user, be this performance enthusiast (read overclocker), extreme gamer or indeed for those who require the ultimate media encoding platform. So whatever your vice, Intel have all the bases covered with their latest chipset. This isn't, of course, to say the Z97 based chipset is poor by comparison (its not), but if you want the ultimate - the very best of the best supporting Intel's 8 core processor (5960X) - then X99 is the only option.

So what's new with X99?

DDR4 Quad Channel Memory
The above block diagram shows us that DDR4 is natively supported. Note that DDR3 is NOT supported (more on this later). While the block diagram shows a rated speed of up to 2133MHz, our test bench happily ran 16GB (4x4GB) Quad channel Corsair Vengeance LPX at 2666MHz. More recently niche 3000MHz and even 3333MHz DDR4 DIMMs are entering the market requiring high voltages and far deeper pocket, but its anticipated that eventually 4GHz DIMMs will be the high watermark at retail.

40 x PCI Express (PCIe) Lanes
Depending on CPU choice, the X99 chipset can support up to 40 lanes of PCIe in combinations of 2x16, 1x8 or 5x8. We also expect this figure to increase on some motherboards with the addition of PLX chips given sufficient demand. All of the PCIe lanes are now PCIe 3.0 compliant; while current generation GPU's rarely saturate PCIe 2.0 it is nice to have that future proofing available, especially for SLI/Crossfire configurations.

USB 3.0
One of the heaviest criticisms of X79 was the lack of natively support USB 3.0 ports, especially when compared to its Z87/97 brethren. We are now happy to report that X99 will support 6 USB 3.0 ports along with 8 USB 2.0 ports. Of course, most motherboard manufacturers will also add the usual 'aftermarket' USB 3.0 support from components such as ASMedia and Marvel so transfer speeds of up to 5GB/s and port numbers in the double-digits can theoretically be achieved.

SATA 3.0 And Next Generation Storage
Despite having huge computational benefits, X79 was oft criticised by the lack of high speed SATA 6Gbps ports. This has been rectified with the X99 chipset supporting 10 x SATA 3.0 ports attaining a theoretical speed of 6Gb/s which can be enhanced using the latest Intel Rapid Storage driver to speeds of 10 Gb/s!

SATA of course has its limitations, which is where newer next generation storage technologies come in. First seen in limited quantities on Z87 and more widely on Z97, M.2 and SATA Express technologies unlock transfer speeds far in excess of SATA III. Support for PCIE storage remains sporadic M.2 is starting to pick up but SATA Express is exceptionally rare but its slowly proving to be a valid alternative to SATA 3 and mSATA. Many X99 motherboards support M.2 X4, which makes use of four PCIE lanes for up to a stunning 32Gbps bandwidth; however few M.2 drives come close to saturating even Gen 1s ~8Gbps.

We must say that Intel have pulled out all the stops here. Clearly they have taken on board user feedback regarding the deficiencies of X79 by incorporating more modern storage and expansion options. No longer is the Enthusiast flagship the poor I/O brother to Z87/97. Perhaps the biggest draw though is the introduction of DDR4. This will see huge speed gains in almost every aspect of personal computing. With 8x8GB Dimms supported a mammoth 64GB of DDR4 will make the X99 chipset massively future proofed.

We will cover the overclocking capabilities of the new chipset and each motherboard specifically in the overclocking section but this area failed to disappoint too.

Overall, there is little to criticise here. While we would have liked 40 PCIe lanes regardless of CPU, we understand there has to be some compromise to keep costs down for the budget conscious so how many PCIe lanes you have available will be dictated by CPU choice and not the motherboard. The entry level 6 core i7-5820 will have 28 PCIe lanes at a cost of 299 (At the time of release), while the flagship 8 core i7-5960X and 6 core i7-5930K will both have the full blown 40 lanes available. Aside from lanes, cores cache and clockspeed, all of the X99 features will be available regardless of CPU choice and to this end we are grateful. We suspect that future additions to the CPU range will hit the middle ground while the 5960X will receive a speed bump although this is pure speculation at this point.

Which chip would we go for? Obviously if money was no object then the i7-5960X is the way to go, not only does it have the full 40 lanes available but it is a true 8 core (16 threads) CPU. The 5930K would be the obvious choice for the consumer and the CPU that we think will prove most popular due to the balance of speed vs. cost.

Whichever CPU you opt for though, you can be assured that the X99 chipset offers the very best available. It is powerful, feature packed and as you will see, the unrivalled component of choice for enthusiast users.
