   “AMD Radeon Adrenalin 19.2.2
   “AMD Radeon Adrenalin 19.2.2 Driver Update”

   After installing Adrenalin 19.2.2, lots of folks testing auto-overclocking with auto-undervolting and geting more towards, and actually above, that 2000Mhz OC.

   Will more Radeon VII testing be forthcoming with OC in mind?

   Also just how much heat reduction and fan noise can be reduced with undervolting on Radeon VII?

   The Limited Pro Driver stuff is good but No xGMI on the consumer Vega 20 variants.

   Now for Radeon Pro Duo(Vega 20 edition)!

     Yes, a follow up with some OC

     Yes, a follow up with some OC results is planned. I’d like to see how much more I can get from this card, was hoping 1800 MHz wasn’t the effective limit and it sounds like it’s not!

       But not just overclocking as
       But not just overclocking as the primary reason but also some undervolting testing also with a look towards comparsion of Vega 20(Radeon VII)/7nm against Vega 10(Vega 56/64)/14nm undervolting results and the better power/performance usage metrics across the Fab nodes that AMD makes us of information available. So undervolting Radeon VII while having the data sets on the record and creating sufficient undervolting samples rates for everyone to make use of.

       There are folks getting better firestrike numbers on Radeon VII while geting the power usage down towards Nvidia’s range of power usage. So some games performance is not affected adversely by the Radeon VII undervolt but Radeon VII’s power usage metrics are becoming more competative because of Radeon VII’s undervolting, while remaining stable, headroom is so mcuh better on TSMC’s 7nm process relative to GF’s 14nm node.

       It’s common Knoledge that AMD tends to go with the higher voltages in order to obtain the highest numbers of GPU die samples that fit the binning range on AMD’s consumer GPUs.

       That equates to more websites doing more undervolting for Radeon VII/TSMC 7nm and having a larger sample size available to get a more accurate look at that TSMC’s 7nm process potential with AMD’s GPU designs.

       No one is expecting a direct comparsion with Nvidia and Nvidia being unhappy about that. Folks will be fine with Radeon VII’s undervolting potential on TSMC’s 7nm node compared to Vega 56’s/64’s SKUs undervolting potential on GF’s 14nm node because that still results in some available metrics for folks to do their own comparsions to whatever they desire.

   Ok, So I had this nightmare
   Ok, So I had this nightmare about a terrible, horrible How To Build A PC video! And a few days later I recieve a DCMA takedown request from Vox Media in the mail.

   It stated that I had earned One Strike against me already and that if I had that nightmare 2 more times that my rights to have any wet dreams would be suspended!

     Thanks for letting us know.

     Thanks for letting us know. I'm seeing it too and I've got the developers looking into it. We think it's related to some issues our ad configuration is having right now and nothing malicious but nobody's going to blame you if you want to throw us behind an ad blocker until it's resolved.

       It’s not just PCper that
       It’s not just PCper that browser message was popping up on a lot of different websites at the same time and if the browser is warning then it must not be properly signed js that getting pushed out there.

       This is why the entire Internet Ad industry needs to be forced to have their ad Images/Content and assoicated ad JS Vetted/Ceritfied with an industry wide Ad Testing/Vetting entity. And let every ad be published to that entity and tested/vetted and identified before it’s allowed to be pushed over the interwebs.

       Make the ads’ creators have to register their their ads with a unique identifier including having that ads programmer/s’ names encripted along with other metadata that the industry wide Ad Testing/Vetting entity holds the encryption keys to.

       That will put a stop some of the more egregiously inefficient and resource hogging ad/ad script writers from pushing their garbage out there while also maintaing more securtiy in the chain of ad production to those ads that are pushed out into the browsers that have to display that ad content. The ad industry needs more rules and accountability.

   Is CTS-Labs up to some new
   Is CTS-Labs up to some new antics and why are there so many AMD Laprops that come with 2 memory channels only shipped with a single channel of memory populated and the other slot remains unpopulated.

   Better yet how many review sites are testing these laptops with half the available memory channels/DIMM slots populated by the laptop OEMs on AMD’s offerings ->as is<- instead of calling that out. Go into any Microsoft store and the only place that you will find AMD is in the MS Gaming Console SKUs and not in any of the laprops. Are things getting more or less incentivised by the majority market place holder and New laptops with AMD's APUs have just been reviewed on some sites but the "New" laptop is still using the 14nm/Zen 2000 series APUs and not the just released 12nm/Zen+ 3000 series based Picasso APUs. Those Only single channel of a 2 memory channels/DIMM slots populated OEM laptop's benchmarks sure are not showing the Vega integrated graphics performance potential in a fair manner and yet the reviews continue unabated with AMD's Integrated Vega Graphics only afforded half the memory bandwidth that the laptop is capable of providing. The more things Change for AMD and its Zen+ cores with Better peforrming Vega Integrated Graphics the more the laptop market stays the same with AMD getting the the short end of the stick by the laptop OEMs that may just be the best friends the big chip monopoly's incentives can buy! AMD's heading uphill trying to get over the competition's mountain the size of Everest, no make that Olympus Mons, sized incentives! And even with Zen/Zen+ getting closer to Intel's single core IPC and Zen-2 on the way and more signs of single core IPC gains for AMD while Integreted Vega Graphics is some bit better than what the competition offers. Is it better performance of better incentives that rule that OEM laptop market, with a little on the Side for CTS-Labs to do their master's bidding!

   NiceArticleAndInterviewFromEurogamerDigitalfoundry on February 17, 2019 at 8:12 pm

   Great article/interview(1)
   Great article/interview(1) from Eurogamer/Digital Foundry and with Metro Exodus 4A games engine rendering programmer Ben Archard and the developer’s CTO, Oles Shishkovstov. And the ray tracing on next generation consoles question and Ray’s Traced via the GPU’s shader cores or CPU cores and not necessarily on any dedicated RT cores.

   So in the quoted text below Eurogamer/Digital Foundry asks about ray tracing on next generation consoles:

   “Let’s talk about ray tracing on next-gen console hardware. How viable do you see it to be and what would alternatives be if not like RTX cards we see on PC? Could we see a future where consoles use something like a voxel GI solution while PC maintains its DXR path?

   Ben Archard: it doesn’t really matter – be it dedicated hardware or just enough compute power to do it in shader units, I believe it would be viable. For the current generation – yes, multiple solutions is the way to go.

   This is also a question of how long you support a parallel pipeline for legacy PC hardware. A GeForce GTX 1080 isn’t an out of date card as far as someone who bought one last year is concerned. So, these cards take a few years to phase out and for RT to become fully mainstream to the point where you can just assume it. And obviously on current generation consoles we need to have the voxel GI solution in the engine alongside the new RT solution. RT is the future of gaming, so the main focus is now on RT either way.

   In terms of the viability of RT on next generation consoles, the hardware doesn’t have to be specifically RTX cores. Those cores aren’t the only thing that matters when it comes to ray tracing. They are fixed function hardware that speed up the calculations specifically relating to the BVH intersection tests. Those calculations can be done in standard compute if the computer cores are numerous and fast enough (which we believe they will be on the next gen consoles). In fact, any GPU that is running DX12 will be able to “run” DXR since DXR is just an extension of DX12.

   Other things that really affect how quickly you can do ray tracing are a really fast BVH generation algorithm, which will be handled by the core APIs; and really fast memory. The nasty thing that ray tracing does, as opposed to something like say SSAO, is randomly access memory. SSAO will grab a load of texel data from a local area in texture space and because of the way those textures are stored there is a reasonably good chance that those texels will be quite close (or adjacent) in memory. Also, the SSAO for the next pixel over will work with pretty much the same set of samples. So, you have to load far less from memory because you can cache and awful lot of data.” (1)

   The long article goes into greater detail on 4A’s methods and IP but is definitely indepth and worth reading.

   Intresting article about
   Intresting article about AMD/Epyc server market share and AMD’s renewed server market potential. It’s got several historcial market comments related to ServeTheHome’s time as an online publication and how that spans Opteron circa 2009 to the current time and just what AMD did back then and what AMD is doing now with its Zen/Epyc offerings.

   This includes some additional insights into the past Opteron motherboard options(1P, 2P, and 4P) into renewed competative sever market offerings built around AMD’s new Zen/Epyc x86 and current SP3(1P, 2P only) motherboard offerings.

   The article also places in proper context and explains those 2 conflicting Market Research Aanaysis Firm’s differing server market share figures for AMD’s Epyc server market share since its first Zen micro-arch based Epyc/Naples line became available for the server market.
