Even after years of suggestions and beratement, CMOS battery placement remains a sore spot for a variety of reveiwers.  The Crosshair VII Hero is no exception, where the battery will be buried under you GPU; what is exceptional is that this is the sole shortcoming to this AM4 board.  [H]ard|OCP were duly impressed by the features and performance of this board, as well as the price tag, which is nicely under $300.   Whether you plan on taking advantage of Precision Boost 2 or manually overclocking, this is a board worth checking out.

"Along with the second generation AMD Ryzen CPUs, we are getting the new and somewhat improved X470 chipset motherboards. We have been beating on the Crosshair VII Hero for about a month now and have figured out what we like about, outside of it being an excellent overclocker for the Ryzen 7 CPUs."

Upon first meeting the Asus ROG Crosshair VII Hero Kitguru were impressed with the features and design of the board but underwhelmed by the performance.  After contacting ASUS they received a new BIOS and resumed testing, publishing their results here.   The board now performs admirably on the default settings, at the cost of an extra ~40W of power being consumed, while when manually clocked you can replicate the performance but without that extra power draw.

Kitguru explains how Synchronous and Asynchronous mode differ and how this relates to the extra power draw.  In Synchronous mode the CPU memory and PCIe all share the same clock signal while in Asynchronous mode the CPU clock can be adjusted without any effect on the memory or PCIe clocks.  Check out what they think this means for Ryzen users here.

Tagged: x470, amd, ryzen 2, msi, x470 Gaming M7 AC, Pinnacle Ridge

The reviews for AMD's new chipset are starting to appear, for instance the MSI X470 Gaming M7 AC over at Guru of 3D. The new chipset brings support for DDR4-2933 and 3200 which is worth the investment for Ryzen chips.  The board supports two full speed M.2 4x PCIe slots, with SATA trimmed down to a half dozen.  Of the eight USB ports only one is Type-C but all support 3.1 transfer speeds according to Guru of 3D.  The single LAN connection is backed up by dual WiFi antenna and there is even optical audio out for those special people who make use of it. 

Check out the overclocking results and the fine details right here.

NVMe RAID and StoreMI

With Ken testing all of the new AMD X470 goodness that we had floating around the office here at PCPer, I snuck in some quick storage testing to get a look at just how the new platform handled a typical power user NVMe RAID configuration. We will be testing a few different platform configurations:

  • ASUS Z270 w/ 7700K
    • 1x SSD behind chipset (PCH)
    • 2x SSD (RAID-0) behind chipset (PCH)
    • 1x SSD directly connected to CPU
  • AMD X470 w/ 2600X
    • 1x SSD via RAIDXpert bottom driver
    • 2x SSD (RAID-0) via RAIDXpert
    • 1x SSD via MS InBox NVMe driver

For the AMD system we tested, all M.2 ports were direct connected to the CPU. This should be the case for most systems since the AMD chipset has only a PCIe 2.0 x4 link which would cut most NVMe SSD bandwidth in half if passed through it. The difference on AMD is that installing the RAIDXpert software also installs a 'bottom driver' which replaces the Windows NVMe driver, while Intel's RST platform handles this process more in the chipset hardware (but is limited to PCIe 3.0 x4 DMI bandwidth). Now onto the results:

Random Read IOPS

random.png

For random IO, we see expected scaling from AMD, but do note that IOPS comes in ~40% lower than the same configuration on Intel's platform. This is critical as much of the IO seen in general use is random reads at lower queue depths. We'd like to see AMD doing better here, especially in the case where a single SSD was operating without the interference of the RAIDXpert driver, which was better, but still not able to match Intel.

Random Read Latency

latency.png

This latency chart should better explain the IOPS performance seen above. Note that the across the board latency increases by ~10us on the X470 platform, followed by another ~20us when switching to the RAIDXpert driver. That combined ~30us is 50% of the 60us QD1 latency seen the Z270 platform (regardless of configuration).

Sequential Read

sequential.png

Ok, now we see the AMD platform stretch its legs a bit. Since Intel NVMe RAID is bottlenecked by its DMI link while AMD has all NVMe SSDs directly connected to the CPU, AMD is able to trounce Intel on sequentials, but there is a catch. Note the solid red line, which means no RAIDXpert software. That line tracks as it should, leveling off horizontally at a maximum for that SSD. Now look at the two dashed red lines and note how they fall off at ~QD8/16. It appears the RAIDXpert driver is interfering and limiting the ultimate throughput possible. This was even the case for a single SSD passing through the RAIDXpert bottom driver (configured as a JBOD volume).

StoreMI

2018-04-19-08-49-39.png

AMD has also launched their answer to Intel RST caching. StoreMI is actually a more flexible solution that offers some unique advantages over Intel. Instead of copying a section of HDD data to the SSD cache, StoreMI combines the total available storage space of both the HDD and SSD, and is able to seamlessly shuffle the more active data blocks to the SSD. StoreMI also offers more cache capacity than Intel - up to 512GB SSD caches are possible (60GB limit on Intel). Lastly, the user can opt to donate 2GB of RAM as an additional caching layer.

2018-04-19-08-49-55.png

AMD claims the typical speedups that one would expect with an SSD caching a much slower HDD. We have done some testing with StoreMI and can confirm the above slide's claims. Actively used applications and games end up running at close to SSD speeds (after the first execution, which comes from the HDD). StoreMI is not yet in a final state, but that is expected within the next week or two. We will revisit that topic with hard data once we have the final shipping product on-hand.

Gigabyte's New X470 Aorus Motherboards Are Available For Pre-Order

Subject: Motherboards | April 16, 2018 - 04:40 PM |
Tagged: gigabyte, aorus, x470, AM4, amd, aorus gaming 7 wifi, aorus ultra gaming

Gigabyte is gearing up for AMD’s second-generation Ryzen processors with three new Aorus motherboards based on the X470 chipset. The new boards include the Gigabyte X470 Aorus Ultra Gaming, X470 Aorus Gaming 5 WIFI, and the X470 Aorus Gaming 7 WIFI. These motherboards represent a refreshed and improved design over their X370 predecessors particularly when it comes to VRM cooling as the heatsinks have been vastly improved. Gigabyte has also refreshed the audio with an updated Realtek ALC1220-VB audio codec and ESS SABRE DAC. Other features Gigabyte notes are upgraded 802.11ac Wave 2 Wi-Fi, dual PCI-E x4 M.2 slots with heat spreaders, USB Type-C support, four RGB LED headers including support for digital LEDs, and Smart Fan 5 technology for managing system cooling and fans attached to the board. The new motherboards feature a up to a 10+2 power phase design using digital VRMs from IR and a 8+4-pin power connector. The power phases are cooled by two heatsinks that use a “stacked fins array” and direct touch heatpipes.

The new X470 motherboards all have four DDR4 DIMM slots, six SATA 6 Gbps ports, three PCI-E x16 slots, two PCI-E x1 slots, two PCI-E x4 M.2 slots, and Realtek-based audio with high end capacitors and op amps. Around back the boards offer USB 2.0, 3.1 Gen 1, and 3.1 Gen 2 ports including a USB Type-C port, Gigabit Ethernet, six audio jacks, and two WI-Fi antenna connectors on the Wi-Fi boards.

In most respects the three motherboards are the same, but as you move up Gigabyte adds a bit more power delivery hardware, more built-in RGB, a bit more slot armor, and a bit more shielded audio. The Ultra Gaming board is the lowest end offering with RGB only on the chipset and audio path, and there is no second M.2 shield or PCI-E and RAM slot armor. This board also has the least amount of shielding and extra caps on the integrated audio and the smallest VRM heatsinks. Moving up the Gaming 5 Wi-Fi gets you RAM slot armor, a shielded audio path, and RGB around the PCI-E slots and above the rear I/O. Of course, it also give you built-in Wi-Fi. Further, moving to the X470 Gaming 7 Wi-Fi cranks up the RGB to include the third PCI-E slot, the customizable RGB plate on the right edge, RGB around the RAM slots, and more RGB over the VRM heatsinks. The motherboard also adds an integrated baseplate behind the motherboard, additional Nichicon capacitors for the audio, and the rear I/O panel includes additional USB ports as well as built-in power and reset buttons. The rear I/O backplate is also built-into the motherboard.

As for power delivery, the Ultra Gaming and Gaming 5 WIFI have a single 8 pin CPU power connector feeding an 8+3 "Hybrid Digital PWM" design with Intersil Digital PWM and Lower RDS(on) MOSFETs which Gigabyte claims run cooler than standard MOSFETs. The Gaming 7 WIFI board steps things up to 8-pin plus 4-pin CPU power connectors and a 10+2 all digital power phase from IR including digital PWM and Power Stage controllers. The phases are broken up into ten for the vCore and two for the SoC.

As far as pricing goes, all three of the AMD motherboards are currently available to pre-order and will ship on April 18th (according to Newegg). The X470 Aorus Ultra Gaming is listed at $139.99, the X470 Aorus Gaming 5 WIFI is listed at $179.99, and the X470 Aorus Gaming 7 WIFI is listed for $239.99. I am interested to see how these motherboards perform especially when it comes to overclocking!

Better late than never to get previews of the second coming of Ryzen up, from two additional sources above and beyond the post below.  Pinnacle Ridge is poised to release next Thursday but there are a few details which have surfaced for our enjoyment about the chips themselves as well as the new Wraith coolers.  The Tech Report offers the few tidbits they are currently able to disclose, such as the infection of RGBs in the Wraith Prism cooler, while TechARP have posted a few leaked benchmarks which may or may not reflect reality as well as a look at the reviewers kit.  We know the Ryzen 5 2600X has six cores and the Ryzen 7 2700X sports eight but so far the only other thing we know for sure is what they both look like physically

Asus Planning ROG Strix X470-I Mini ITX Motherboard

Subject: Motherboards | April 12, 2018 - 01:34 PM |
Tagged: asus, ASUS ROG, ROG Strix, AM4, mini ITX, amd, x470

Asus appears to be planning a Republic of Gamers branded updated motherboard for AMD’s Ryzen 2000 series processors. The ROG STRIX X470-I is a mini ITX form factor board that is loaded with RGB, higher end power phases and onboard sound, and built-in Wi-Fi.

ASUS ROG STRIX X470-I Mini ITX AM4 Motherboard.jpg

Videocardz obtained several images of the new X470 chipset based Mini ITX motherboard.

Asus is using a unique design with this board where it has moved the rear IO down a bit to make room for a larger 8-pin CPU power connector to be tucked into the upper left corner. The AM4 socket is surrounded by the VRMs, two full size DDR4 DIMM slots, and a heat shield that hides the M.2 slot. For storage, there are four SATA 6 Gbps ports (two next to the M.2 slot and two along the right edge) and for graphics cards there is a single PCI-E x16 slot. The board further has a USB 3.0 header, USB 2.0 header, audio header, three fan 4-pin connectors (one AIO pump header), and two RGB headers.

Around back, ASUS has provided a single HDMI output for those wishing to use an APU, four USB 3.1 Gen 1 ports, two USB 3.1 Gen 2 (10 Gbps) ports, Gigabit Ethernet, two 802.11ac Wi-Fi antenna ports, and three LED-backlit audio jacks.

Because this motherboard is a refresh of the X370-I, I think it’s safe to say that it is very likely that Asus is using Intel for the Gigabit Ethernet and the same SupremeFX S1220A codec (with high end Japanese capacitors and dual TI op amps) on the shielded M.2 Audio combo card.

As for the RGB, the board supports Asus Aura Sync and has a 3-pin addressable LED header and a 4-pin RGB header as well as built-in RGB LEDs along the right edge and on the M.2 heatsink.

Not much else is known about this small form factor motherboard, but with the launch of Zen+ coming any week now (allegedly), we should know more soon! You can find more photos of the motherboard over at Videocardz.

With the previous generation X370-I going for $230+ online though, I would not expect the X470-I to be cheap, however. It is interesting that it will continue to carry the ROG and STRIX branding though in light of ASUS moving its Radeon graphics card offerings to a new AREZ brand to get around the whole GeForce Partner Program situation. I am glad to see the SFF boards getting updates this quickly from many manufacturers in time for the launch of the 400 series chipsets and Ryzen 2000 series processors.

Biostar's Refreshed Mini ITX Racing X470GTN AM4 Motherboard Revealed

Subject: Motherboards | April 5, 2018 - 08:27 PM |
Tagged: x470, mini ITX, ddr4, biostar, amd, AM4

Biostar is planning to release an updated Mini ITX AMD motherboard according to leaked images sourced by Videocardz. According to the image, the new board will be called the Biostar Racing X470GTN and will feature the AMD X470 chipset which is a refreshed enthusiast chipset that is supposed to be more power efficient and contain tweaks and optimizations for AMD’s upcoming “Zen+” Ryzen 2000 series of desktop processors and APUs.

Biostar X470 Racing GTN Mini ITX AM4 Motherboard.jpg

The Racing X470GTN looks very similar to the Racing X370GTN that Biostar released last year down to the same black PCB and board component layout though the VRM heatsink has been spruced up a bit and is now in red and white rather than black and white. Further, the X470 chipset heatsink lacks the carbon fiber aesthetic and the PCI-E slot is white instead of black. Lastly, the PCB audio isolation for the onboard audio may have been slightly tweaked. The LED-equipped Mini ITX motherboard is powered by a 24-pin ATX and a 4-pin EPS CPU power connector that feeds the seven phase (4+3) power phases. Unfortunately, the heatsink on the VRMs does not look any larger which may hamper any heavy overclocking attempts on the processor as Hardware Canucks saw rather high temperatures (though not magic smoke bad) at stock clocks on the X370GTN they reviewed. In any event, the AM4 socket sits up top and is surrounded by two DDR4 memory slots, four SATA 6 Gbps ports, and one PCI-E 3.0 x16 slot. There is also a PCI-E M.2 slot hidden behind the board for enthusiasts. The onboard audio codec is a Realtek ALC892 chip (per Videocardz) and while the leaked image does not confirm anything I am guessing the Gigabit Ethernet NIC is also of Realtek origin and is likely the same RTL8118AS used in the previous generation motherboard.

As far as rear I/O is concerned, there is not much to speak of but Biostar does include a decent amount of high speed USB ports with at least two being USB 3.1 Gen 2 and the remaining four being USB 3.0 or USB 3.1 Gen 1 (the X370GTN had USB 3.0 but the X470 update may have bumped these up to USB 3.1 Gen 1 not that it matters in practical terms of speed). In addition to USB, the Racing X470GTN’s rear panel hosts a combo PS/2 port, DVI and HDMI video outputs, Gigabit Ethernet, and six audio outputs (one optical, five analog).

Naturally, being a leak, there is no word on official pricing or availability on this motherboard, but I would guess it will be priced around $120 following the launch of AMD’s Ryzen 2000 series CPUs and 400 series chipsets.
