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."

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.

Remember Ruby, that animated heroine ATI used in tech demos many years back? She has returned recently and is now playable in Quake Champions for those who claim their free key. In addition to appearing in the game, she is also the centre of attention in this announcement from AMD.
If you purchase a new Ryzen 5 or 7 APU, or a RX 560, 570 or 580 you can now claim the Champions pack for Quake Champions for free. The Champions pack will retail for $40 and add access to all current and future characters to your game, including a custom Ruby skin for Nyx. If you purchased one of these products after August 22nd you are eligible to claim your key over at AMDRewards. The contest will run until October 29th or until the keys run out.

Tagged: amd, Vega, vega 56, vega 64
Because so many different video cards are made from a handful of chip designs, there is a group of people who like to see whether a lower-end SKU can be unlocked to behave like a higher-end one. In this case, kdtree on the ChipHell forums has apparently flashed the new AMD RX Vega 56 with the vBIOS from an AMD RX Vega 64. Personally, I would find that a little sketchy, given the difference in stream processor count, but they’re the one with the graphics card.
Turns out, it did something, but it did not magically create an RX Vega 64. The extra 512 shaders are probably disabled at the hardware level, such as with a laser. Your first reaction is probably “well, of course it is...” but, if you remember Polaris, users have software-modified 4GB cards into 8GB cards... so there is some precedence for “maybe AMD put more on the card than they said on the box”.
Oh right, so what did it do? It apparently gave the card a significant overclock. It’s hard to tell under the watermark, but the modified Vega 56 was just a percent or so away from the Vega 64 on 3DMark. I’m guessing a conventional overclock might do the same, but who knows.

Tagged: Vega, amd, raja koduri, HBCC
Techgage has posted a look at what AMD's new HBCC feature in Vega is and how it will help you run games faster. HBCC allows your GPU to treat VRAM as a last-level cache, so that a request for data not currently located in VRAM can be pulled into Vega's HBC for immediate access while simultaneously flushing out data which is no longer needed. In addition to describing how the feature functions they also did quite a bit of testing to determine the real world effect of enabling HBCC in games and benchmarks. Drop by for a look.
"AMD’s Vega GPU architecture brings many notable features to the table, but the one to find its way into Radeon chief Raja Koduri’s heart is HBCC – or “high-bandwidth cache controller”. In this article, we’re going to take a look at what HBCC is, why it offers no benefit right this moment, and talk about what it could offer in the future."

According to a report from Golem.de (German language), with the upcoming Wolfenstein 2: The New Colossus game AMD Vega owners will have the advantage of FP16 shader support from a new version of the id Tech 6 engine. The game supports both DX12 and the Vulkan API, but the use of half-precision calculations - the scope of which has not been specified - will potentially offer higher frame-rates for AMD Vega users.
AMD provided some technical details about Wolfenstein 2 during their Threadripper/Vega tech day, and this new game includes “special optimizations” in the id Tech 6 game engine for AMD Vega hardware:
“For what exactly id Software (is using) FP16 instead of FP32, AMD did not say. These could post-processing effects, such as bloom. The performance should increase in the double-digit percentage range, (though) id Software did not want to comment on it.” (Translated from German.)
