Malaphax Posted May 9, 2017 Report Share Posted May 9, 2017 I'm interested in seeing Id and what they push out for their new games like quake champions: http://techreport.com/news/31799/id-software-talks-about-ryzen I expect that as more companies start to make use of better resource management and proper usage of multi-thread multi-core we'll see graphs like the one you posted change. The fact that there's a linear trend from 2-6 core is already a good trend, so at this point we can hope that the ultra-high end core/thread setups will see some of those same performance gains.

Apart from the chilling killer design, two boards come with two HDMI outputs, 802.11ac WiFi solution, 7.1-CH with Realtek ALC 1220 codec, heatsinks that effectively improve heat dissipation and promotes overall performance.

kuhla Posted June 29, 2017 Author Report Share Posted June 29, 2017 article - http://www.anandtech.com/show/11591/amd-launches-ryzen-pro-cpus-enhanced-security-longer-warranty-better-quality Quote A superset to the standard Ryzen chips, the PRO chips have the same feature set as other Ryzen devices, but also offer enhanced security, 24 months availability, a longer warranty and promise to feature better chip quality. .... The Zen microarchitecture features two important technologies: Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV) that protect data in DRAM using a dedicated AES-128 engine. .... First off, the Ryzen PRO platforms support the DASH management protocol, allowing PRO systems to be remotely managed using tools based on this industry standard (and typically developed by the individual computer vendors). .... Specifically, AMD is promising that the Ryzen PRO family will offer an 18 month window for platform stability and 24 month of processor availability. .... The reason why AMD offers extended warranty for its business CPUs (apart from the fact that its customers demand this) is because it uses wafers with highest yields/least amount of defective parts to build the Ryzen Pro. .... I assume there will be a cost premium but I don't see why these wouldn't be considered the "best" versions mainly due to the better yields. Binning may not matter as much and features would probably be supported on most consumer boards. Quote Link to comment Share on other sites More sharing options...
kuhla Posted August 10, 2017 Author Report Share Posted August 10, 2017 "The AMD Ryzen Threadripper 1950X and 1920X Review: CPUs on Steroids" article - http://www.anandtech.com/show/11697/the-amd-ryzen-threadripper-1950x-and-1920x-review For the consumer/enthusiast I think the conclusion is pretty much the same as it was for the Ryzen consumer models: AMD can get you more cores for less money which may give you more value, depending on your use, but for many applications Intel is still performance king. I was a little surprised at the Creator Mode vs Game Mode system they had to implement to support some games (example given in article is DiRT) which apparently will not run in a system with more than 20 threads. I didn't know such a problem existed. Quote Link to comment Share on other sites More sharing options...
Malaphax Posted August 10, 2017 Report Share Posted August 10, 2017 I think that compatibility issue with certain programs/games is fairly edge case. I wonder if that's because Dirt uses a proprietary engine (EGO) which simply wasn't designed to scale to that level. I also wonder why it wouldn't default to 16 cores or just not make use of the additional cores rather than completely failing to run. Seems like a weird solution to handle what I would consider a software issue. Still glad to see AMD is making a decent showing in the high end space. I hope they can keep it up and that Intel doesn't sit on their ass, although if recent announcements are anything to go by they're actually in panic mode, which is causing it's own issues.

Malaphax Posted September 18, 2017 Report Share Posted September 18, 2017 Quote Overclocker Roman Hartung (der8auer) discusses his delidding of a Threadripper CPU in a new video: he confirms that AMD is, in fact, using four functional Ryzen dies to create a single Threadripper chip. Being that AMD’s EPYC server processors are made the exact same way, der8auer speculates that the company has plans for a 32-core desktop processor (the choice of using four dies was intentional). https://hardforum.com/threads/threadripper-delidding-uncovers-epyc-in-disguise-32-core-desktop-cpu-in-the-works.1944012/ AHHAHAHAHA What? I mean I knew that their process was silly but are they just binning EPYC cpu's for threadripper? This sounds so... AMD. Every time I hear of AMD doing super weird shit like this I imagine the Russian space program engineers - "Hey vladimir we can build a small rocket engine that works very well, but how do we build a bigger rocket?" 'That is easy ivan, we just attach more rocket engines' Quote Link to comment Share on other sites More sharing options...
Jedi2155 Posted September 22, 2017 Report Share Posted September 22, 2017 Have you seen the recent Soyuz rockets? Its almost as much as the N1.https://en.wikipedia.org/wiki/Soyuz_(rocket_family)#/media/File:Soyuz_rocket_engines.jpg SpaceX kinda follows a similar design with their Falcon Series... Kinda crazy with the 4 die design though. Now that caching strategy makes so much more sense. Quote Link to comment Share on other sites More sharing options...

kuhla Posted September 27, 2017 Author Report Share Posted September 27, 2017 With the socket staying the same, I hope the chipset support comes along for the ride and my board can stay relevant for a few years. Quote Link to comment Share on other sites More sharing options...
Malaphax Posted September 27, 2017 Report Share Posted September 27, 2017 Hey... about that chipset support: Quote AMD spoke with its partners and plans to launch in February 2018 an upgrade version of its Ryzen series processors built using a 12nm low-power (12LP) process at Globalfoundries. The corresponding chipsets, the 400 series, will also become available in March 2018 with X470- or B450-based motherboards to be the first to hit the store shelves. The chipsets are still designed by ASMedia and its orders for the chipsets are expected to grow dramatically starting January 2018. http://www.guru3d.com/news-story/amd-to-launch-12nm-ryzen-in-february.html I'm glad they're not doing the super dumb stuff like intel swapping out their sockets but the new chipsets sounds... crappy. I mean ryzen launched less than 1 year ago and they're already scheduling an upgrade with a new chipset. I guess we may never see m-atx x370 boards. I'm sort of expecting mobo manufacturers to just pump and dump whatever they can on the newer stuff. Hopefully this time the mobo manufacturers have enough lead time to design boards and stable bios so we're not playing the "why is my bios updating more often than my gpu driver" game. I don't want to look too far ahead into the future - but I have a feeling I'll be pushing for an upgrade when ryzen 2 comes out. Quote Link to comment Share on other sites More sharing options...

Maybe even 2800. Opens up some 32GB options too. The statement that Ryzen is sensitive to memory speeds is still true. That one handbrake test and the winrar test were both 15% difference between 2400 and 3200. I don't think I would be comfortable recommending memory slower than 2800 to someone building for Ryzen.

Malaphax Posted September 27, 2017 Report Share Posted September 27, 2017 Yea the 32gb kits are mostly $300+ which is probably too expensive to reasonably recommend. As you've previously mentioned, caring about the timings is one thing, but the bigger issue might be samsung b die vs hynix. I've heard the problems with hynix are mostly fixed, but I haven't read into the issue that much, and I'd rather just dodge that bullet altogether. Sidenote, the 32gb kits supposedly get faster speeds because of the dual rank memory being a bit faster on ryzen (or is that universal?), although I have no idea if that's old news at this point either. This older reddit thread is what I was briefly skimming and referring to: https://www.reddit.com/r/Amd/comments/62vp2g/clearing_up_any_samsung_bdie_confusion_eg_on/ Quote Link to comment Share on other sites More sharing options...

This is universal and has been true for a long time. That being said, there is some debate on whether the difference just show up in benchmarks. Then there is the single sided, double sided situation..... It's a deep rabbit hole and I'm glad that none of it makes a huge impact these days.

kuhla Posted February 12, 2018 Author Report Share Posted February 12, 2018 AMD Ryzen 5 2400G & Ryzen 3 2200G Review, HardwareCanucks, Page 15 - http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/77176-amd-ryzen-5-2400g-ryzen-3-2200g-review-15.html AMD Ryzen 5 2400G, $169, Microcenter instore - http://www.microcenter.com/product/503184/Ryzen_5_2400G_Quad_Core_AM4_Boxed_Processor_with_Wraith_Stealth_Cooler So if you were building a new PC, are strapped for cash, casually play a couple of popular games at 1080p then the 2400G seems like a pretty reasonable choice combined with some decent DDR4 memory. Of course if someone is willing to look at used parts and raise their budget just a little bit then much better options open up but that is not for everyone.

Malaphax Posted February 13, 2018 Report Share Posted February 13, 2018 More to your point. Intel does not have a competing integrated graphics option. I think this allows AMD to provide an alternative in the low(er) end market. Quote Link to comment Share on other sites More sharing options...
Jedi2155 Posted February 14, 2018 Report Share Posted February 14, 2018 As I realized my usage patterns have changed significantly, I'm seriously considering a Ryzen chip for my next build. I've also recently been experiencing odd CMOS resets on my system (BIOS losing all configuration upon boot) regularly so I might be due for an upgrade sooner rather than later.

Malaphax Posted March 13, 2018 Report Share Posted March 13, 2018 I'm sure Kuhla could shed more light on this, but it sounds like there are vulnerabilities being made public that specifically exploit Ryzen's secure processor chip and Asmedia components. https://wccftech.com/report-alleges-amd-ryzen-epyc-cpus-suffer-13-fatal-security-flaws/https://www.amdflaws.com/ Quote CTS-Labs has given AMD 24 hours to respond to its report, which is substantially short of the 90 day grace period normally given to hardware makers to address security issues. My gut reaction is this is a PR hitjob. It's a small Israeli firm that suddenly comes out with info on "VULNERABILITY ONLY IN AMD PRODUCTS!!!" and what little I see about these vulnerabilities all require physical root access or even flashing bios. /r/netsec post about this:https://www.reddit.com/r/netsec/comments/844ok3/severe_security_advisory_on_amd_processors/ EDIT Yet one more reason I believe this is a PR hitjob. I just stumbled across this on /r/securityanalysis - pdf warning - https://viceroyresearch.files.wordpress.com/2018/03/amd-the-obituary-13-mar-2018.pdf It's a "research" document talking about this recently addressed vulnerability. This thing is 25 pages of pure bullshit. I know some analysts are fast, but I think there's not just some absurd bias but some complete nonsense. Here's the quote that's bolded on page 1: Quote We believe AMD is worth $0.00 and will have no choice but to file for chapter 11 (bankruptcy) in order to effectively deal with the repercussions of recent discoveries. Uh huh, what's worse is the "research" paper flat out lies about the vulnerabilities. It's talking about remote access. After searching the whitepaper for the keyword remote, I can't find anything talking about remote access. I can find plenty talking about either flashing bios (physical access) or local elevated admin access (lol, ok) to make use of these "vulnerabilities."

Malaphax Posted March 16, 2018 Report Share Posted March 16, 2018 Here's an interview with anandtech and the CTS Labs people:https://www.anandtech.com/show/12536/our-interesting-call-with-cts-labs I'm glad to see anandtech calling them out on some bullshit. These are technical exploits but the chance of them affecting large enterprise environments are very very small because of the need for physical access and local admin privileges. I still strongly believe this is a PR hitjob and these guys are trying their best to make a name and get on someone else's payroll. I also have huge issues with the fact that Viceroy had a goddamn 25 page pdf ready to rumble at the same time this stuff was made public. I strongly suspect that both of these bad actors were shorting AMD hard and attempting to draw some serious negative attention. Quote Link to comment Share on other sites More sharing options...
Malaphax Posted March 21, 2018 Report Share Posted March 21, 2018 I believe this will be the last time we heart of the AMD exploits posted by CTS. This is an official post from AMD which shows that the exploits are verified and that they're taking steps to remedy the situation. It also correctly mentions that all of these attacks need admin access in order to be utilized. https://community.amd.com/community/amd-corporate/blog/2018/03/21/initial-amd-technical-assessment-of-cts-labs-research Quote Link to comment Share on other sites More sharing options...
