AMD Raven Ridge Performance Leaks - APU with GeForce MX150 Performance

Hot on the heels of the HP leak that showed the first AMD Raven Ridge based notebook that may be hitting store shelves later this year, another leak of potential Raven Ridge APU performance is cycling through. The AMD Ryzen 7 2700U with integrated Vega-based graphics architecture, and also rumored to have a ~35-watt TDP, is showing 3DMark11 graphics scores near that of the discrete NVIDIA GeForce MX150.

With a graphics score of 4072, the integrated graphics on the upcoming AMD APU is slightly behind the score of 4570 from the MX150, a difference of 11.5%. Interestingly, the Physics score on the Raven Ridge APU of 6419 is solid as well, and puts an interesting light on the 8th gen KBL-R processors. As you can see in the graph below, from two systems we already have in-house with quad-core parts, CPU performance is going to vary dramatically from one machine to the next depending on the thermal headroom of the physical implementation.

The HP Spectre x360 with the Core i7-8550U and the MX150 GPU is able to generate a Physics score of 8278, well above the leaked result of the Raven Ridge APU. However, when we ran the 3DMark11 on the ASUS Zenbook 3 UX490UA with the same Core i7-8550U, the Physics score was 6627, a 19% drop! Clearly there are configurability shifts that will adjust the performance of the 8th gen Intel parts. We are diving more into this effect in a couple of upcoming reviews.

Though the true power consumption of these Ryzen 7 2700U systems is still up in the air, AMD has claimed for some time that it would have the ability to compete with Intel for the first time in several generations. If these solutions turn out to be in the 35-watt range, which would be at or lower than the typical 15-watt Intel CPU and 25-watt NVIDIA discrete GPU combined, AMD may have a winning combination for mobile performance users to entertain.

Raven Ridge rumours

If the rumours are true, the new 14nm Raven Ridge based AMD Ryzen 5 2500U will offer an impressive jump in performance compared to AMD's current generation of APUs.  The Inquirer's source suggests the new APU will offer a 50% jump in single threaded performance and an impressive 90% advantage on multi-threaded performance.  The multithreaded performance improvement may be the headline but seeing a huge increase in single threaded applications, AMD's recent Achilles Heel, shows some interesting improvements to Zen.  This will also mark the arrival of their first APU with Vega onboard, so you can expect better graphics performance as well.  The benchmark numbers and links are here.

"LEAKED BENCHMARKS for AMD's forthcoming Raven Ridge APUs suggest that upcoming devices, expected to be launched in time for Christmas, will outperform current Bristol Ridge APUs by up to 90 per cent on multicore applications."

AMD Ryzen 5 2500U APU With Vega Graphics Spotted in Geekbench Benchmarks

Subject: General Tech | September 16, 2017 - 03:32 AM |
Tagged: Zen, Vega, ryzen 5, ryzen, raven ridge, APU, amd

Back in May AMD made Ryzen Mobile official indicating that the APUs previously known as "Raven Ridge" would be launching in the second half of 2017. As that launch window closes, more details are starting to trickle out including benchmarks scores. The latest appearance of Raven Ridge is in a Geekbench benchmark score results page where a "Ryzen 5 2500U" APU achieves a single core score of 3,561 and a multi-core score of 9,421. These are fairly impressive results on their own, but especially considering that Ryzen Mobile chips are reportedly using up to 50% less power versus last generation Bristol Ridge processors while handily beating them in performance offered.

AMD has previously claimed that its Ryzen Mobile (Raven Ridge) APUs will offer up to 50% more CPU performance and 40% more GPU performance compared to its 7th Generation APUs. The leaked Geekbench scores seem to back up those claims (for the most part) with the Ryzen 5 2500U scoring slightly above 36% better single core performance and 48% better multi-core performance compared to the AMD A12-9800 APU with the latter being due primarily to the addition of SMT to the processor design allowing for twice the number of CPU threads (eight total). The performance improvements are also due to the move from Excavator to a Zen-based design on a smaller more power efficient process node. What is most impressive about this mobile part is that it is that much faster than a 65W quad core (4 core / 4 thread) desktop Bristol Ridge APU clocked at 3.8 GHz base and 4.2 GHz boost while using approximately half the power!

The Geekbench benchmark is only one data point, but is still a positive sign. One thing it does not reveal is clockspeed as while it lists 2.0 GHz that number is likely only the base and not the maximum boost frequency. Further, details on the Vega-based GPU are still unknown although the Infinity Fabric should help tremendously in reducing the bottleneck and keeping the on die GPU fed with data while gaming especially when paired with fast dual channel memory or HBM (I just hope that Ryzen Mobile is not held back like previous generation mobile APUs were with laptop manufacturers pairing them with single channel memory setups). We also do not know officially the number of stream processors that will be included in any of the Vega GPUs used in Ryzen Mobile with past rumors going up to 1024 SPs (mobile parts will likely be capped at 512 or 768 at the extreme). AMD claims that Ryzen Mobile will offer up to 40% more GPU performance, which to me suggests that we will possibly see higher GPU core counts but for the most part performance improvements are going to come from architecture improvements.

I am really interested to see how Raven Ridge plays out and hope that it is one step closer to finally realizing that HSA future AMD has been promsing me for years!

Gigabyte Launches GA-AB350N-Gaming WIFI Mini ITX AM4 Motherboard

Subject: Motherboards | June 28, 2017 - 01:44 AM |
Tagged: gigabyte, mini ITX, b350, amd, AM4, raven ridge, SFF, ryzen

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.

Gigabyte GA-AB350N-Gaming WIFI.png

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 Teases Ryzen Mobile APUs with Zen CPU Cores and On-Die Vega Graphics

Subject: Processors | May 18, 2017 - 01:01 AM |
Tagged: Zen, Vega, ryzen mobile, ryzen, raven ridge, APU, amd

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).

AMD Ryzen Mobile APUs.jpg

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?
