Gigabyte is joining the small form factor Ryzen motherboard market with its new GA-AB350N-Gaming WIFI. The new Mini ITX motherboard sports AMD’s AM4 socket and B350 chipset and supports Ryzen “Summit Ridge” CPUs, Bristol Ridge APUs (7th Gen/Excavator), and future Zen-based Raven Ridge APUs. The board packs a fair bit of hardware into the Mini ITX form factor and is aimed squarely at gamers and enthusiasts.
The AB350N-Gaming WIFI has an interesting design in that some of the headers and connectors are flipped versus where they are traditionally located. The chipset sits to the left of CPU socket above the 6-phase VRMs and PowIRStage digital ICs. Four SATA 6Gbps ports and a USB 3.0 header occupy the top edge of the board. Two DDR4 dual channel memory slots are aligned on the right edge and support (overclocked) frequencies up to 3200 MHz depending on the processor used. The Intel wireless NIC, Realtek Gigabit Ethernet, and Realtek ALC1220 audio chips have been placed in the space between the AM4 socket and the single PCI-E 3.0 x16 slot. There is also a single M.2 (PCI-E 3.0 x4 32Gbps) slot on the underside of the motherboard. Gigabyte has also integrated “RGB Fusion” technology with two on board RGB LED lighting zones and two RGBW headers for off board lighting strips as well as high end audio capacitors and headphone amplifier. Smart Fan 5 technology allegedly is capable of automatically differentiating between fans and water pumps connected to the two fan headers and will automatically provide the correct PWM signal based on fan curves the user can customize in the UEFI BIOS. The motherboard is powered by a 24-pin ATX and 8-pin EPS and while it does not have a very beefy power phase setup it should be plenty for most overclocks (especially with Ryzen not wanting to go much past 4 GHz (easily) anyway).
Rear I/O includes:
- 1 x PS/2
- 2 x Antenna (Intel 802.11ac Wi-Fi + BT 4.2)
- 2 x USB 2.0
- 2 x USB 3.1 Gen 2 (10Gbps)
- 4 x USB 3.1 Gen 1 (5Gbps)
- 6 x Audio (5 x analog, 1 x S/PDIF)
- 1 x DisplayPort 1.2
- 1 x HDMI 1.4
- 1 x Realtek GbE
Gigabyte has an interesting SFF motherboard with the GA-AB350N-Gaming WIFI and I am interested in seeing the reviews. More Mini ITX options for Ryzen and other Zen-based systems is a good thing, and moving the power phases to the left may end up helping overclocking and cooling in smaller cases with tower coolers.
Unfortunately, Gigabyte has not yet revealed pricing or availability. Looking around online at its competition, i would guess it would be around $85 though.

AMD teased its upcoming Zen-based APUs aimed at mobile devices during its Financial Analyst Day where the company revealed the "Raven Ridge" parts will be aptly known as Ryzen Mobile. The Tech Report managed to acquire a couple slides which confirm some of the broader specifications and reveal how they stack up to AMD's latest Bristol Ridge A-Series APUs – at least as far as AMD's internal testing is concerned (which is to say not independently verified yet so take with a grain of salt).
Ryzen Mobile appears to be the new consumer-facing brand name for what has so far been code named "Raven Ridge". These parts will use a Zen-based CPU, Vega GPU, and integrated chipset. Thanks to the slides, it is now confirmed that the Vega-based graphics processor will be on-die. What has not been confirmed is whether the chipset will be on die or on package and exact specifications on CPU cores counts, GPU Compute Units, cache, memory support, and I/O like PCI-E lanes (you know, all the good stuff! heh). Note that rumors so far point towards Raven Ridge / Ryzen Mobile utilizing a single 4-core (8-thread) CCX, per core L2, 8MB shared L3 cache, and a Vega-based GPU with 1024 cores. HBM2 has also been rumored for awhile but we will have to wait for more leaks and/or an official announcement to know for sure if these Ryzen Mobile parts aimed for the second half of 2017 will have that (hopefully!).
With that said, according to AMD, Ryzen Mobile will offer up to 50% better CPU performance, 40% better GPU performance, and will use up to 50% less power than the previous 7th generation (Excavator-based) A-Series APUs (e.g. FX 9830P and A12-9730P). Those are some pretty bold claims, but still within the realm of possibility. Zen and Vega are both much more efficient architectures and AMD is also benefiting from a smaller process node (TSMC 28nm vs Samsung / GlobalFoundries 14nm FinFET). I do wonder how high the APUs will be able to clock on the CPU side of things with 4 GHz seeming to be the wall for most Zen-based Summit Ridge chips, so most of the CPU performance improvement claims will have to come from architecture changes rather than increases in clockspeeds (the highest clocked A-Series Bristol Ridge ran at up to 3.7 GHz and I would expect Raven Ridge to be around that, maybe the flagship part turbo-ing a bit more). Raven Ridge will benefit from the shared L3 cache and, more importantly, twice as many threads (4 vs 8) and this may be where AMD is primarily getting that 50% more CPU performance number from. On the graphics side of things, it looks like Bristol Ridge with its R7 graphics (GCN 3 (Tonga/Fiji on the Desktop)) had up to 512 cores. Again, taking the rumors into account which say that Raven Ridge will have a 1024 core Vega GPU, this may be where AMD is getting the large performance increase from (the core increase as well as newer architecture). On the other hand, the 40% number could suggest Ryzen Mobile will not have twice the GPU cores. I would guess that 1024 might be possible, but running at lower clocks and that is where the discrepancy is. I will admit I am a bit skeptical about the 1024 (16 CU) number though because that is a huge jump... I guess we will see though!
Further, I am curious if Ryzen Mobile will use HBC (high bandwidth cache) and if HBM2 does turn out to be utilized how that will play into the HBC and whether or not we will finally see the fruits of AMD's HSA labors! I think we will see most systems use DDR4, but certainly some SKUs could use HBM2 and that would definitely open up a lot of performance possibilities on mobile!
There is still a lot that we do not know, but Ryzen Mobile is coming and AMD is making big promises that I hope it delivers on. The company is aiming the new chips at a wide swath of the mobile market from budget laptops and tablets to convertibles and even has their sights set on premium thin and lights. The mobile space is one where AMD has struggled with in getting design wins even when they had good parts for that type of system. They will really need to push and hit Ryzen Mobile out of the park to make inroads into the laptop, tablet, and ultrabook markets!
AMD plans to launch the consumer version of Ryzen Mobile in the second half of this year (presumably with systems featuring the new APUs out in time for the holidays if not for the back to school end of summer rush). The commercial SKUs (which I think refers to the Ryzen equivalent of AMD Pro series APUs.Update: Mobile Ryzen Pro) will follow in the first half of 2018.
What are your thoughts on Ryzen Mobile and the alleged performance and power characteristics? Do you think the rumors are looking more or less correct?
