hifi posted:This is bullshit, the 9590 didn't even require a $100 cooler and it was a 220W part. On top of that we've already seen the OEM HSFs and the biggest one is still modestly sized compared to the 3rd party offerings. Amazon probably has a thousand dollar PSU to sell you too. The top OEM cooler is rated for 140W TDP and the guys with obvious insider knowledge say that Ryzen around 4 GHz hits 90C on air. Something does not add up there. gamersnexus posted:China-based motherboard manufacturer Maxsun plays an important role in our largely US-driven coverage: The exposure of AMD’s cooling solutions, through branding that states “Support AMD S3.0 Radiator.” From this, we can postulate that AMD’s planning at least one CLC solution for its upcoming Ryzen CPUs, likely alongside a few other stock cooling solutions. We’ll explore that more in a post soon. "Black Bundle" sounds pretty OEM to me, not like something that Amazon came up with. I want AMD to beat Intel's lazy rear as much as any other CPU consumer but it seems likely to me that the 1800X is a highly binned, factory overclocked and very cooling sensitive "Black Edition" SKU with little additional OC headroom. Not that that's a bad thing. On the bright side I recall launch RX480s throttling at more than 150W with stock frequencies. Fast forward a few months and suddenly youtubers reviewed factory overclocked cards that never went above 100W during Firestrike.

Multiple sources have stated that the CPU availability should be plentiful at launch but decent motherboards will be hard to come by. Manufacturers apparently barely had time to finish the designs and did everything to get them out the door with BIOSes lacking optimizations and features, etc. Guess we'll find out soon enough! I fully agree that there's a good chance that later steppings will have significantly more OC headroom but 3.9/4.1 seems realistic and good enough for the top models at this point.

This means that the CPU now carries all the relevant lanes for USB, SATA, NVMe, and PCIe general purpose use, with the chipset offering a few extra lanes and IO devices here and there. eames fucked around with this message at 20:39 on Feb 22, 2017 |

Auron posted:AMD doing something good sounds too good to be true. I'll wait until there's proper reviews/benchmarks/real world tests out there. I expect these to run way hotter than many expect, particularly with XFR and the resulting absence of OC headroom. That's the one missing aspect that never got mentioned in any of the slides or planted leaks, not once. No temps, no details beyond unspecified TDP numbers (possibly at base not including XFR, let alone on all cores), no OC results, nothing. GloFo's gonna GloFo.

oooh juicyreddit posted:AIDA64, HWiNFO and CPU-Z developers not getting Ryzen samples - Ryzen potentially has issues with L2/L3 cache and memory latency source with links TLDR is that L2 and L3 cache latency seems higher than it should be but the AIDA dev doesn't have a sample so he cant tell if it's a software bug, cpu bug, cpu bottleneck or architectural issue. AMD complained about low scores but wouldn't send him a sample. Trying to bench AIDA64 with Ryzen will pop up a warning for the reviewer to ignore the score because "the benchmarks are not properly optimized for the current CPU." Smells like the sort of thing you'd want an NDA for if this is all true. the whole translated post history by an AIDA64 dev can be read here: http://translate.google.com/transla...n&langpair=auto|en&tbb=1&ie=UTF-8 eames fucked around with this message at 23:51 on Feb 22, 2017 |

Judging from the various leaked benchmarks they've exceeded my expectations but all in all a 7600K around 5 Ghz would still be the best value desktop CPU for me (mostly using it for simple casual  ).That's assuming the smaller, lower TDP 4/6 core parts don't turn out to be overclocking beasts which is rather unlikely. Oh and no showstopping bugs and erratas!  AMD needs process improvements from GloFo and more games like Watch Dogs 2 which scale from threads instead of Mhz. There are very good chances that future game engines will do that but by the time a 8-core CPU is better across the board than a 30% faster 4-core CPU, Intel will probably have caught up. Fun fact: an analyst report stated that "over 99%" of Intel's desktop CPUs sold in 2016 included an integrated GPU, so 6-10 core high end desktop CPUs sales accounted for less than 1% of their sales. Not surprising but it puts the whole "6900K killer" hype into perspective.

Nam Taf posted:On the overclocking wall front, if I understand correctly that's probably not a terrible place to be in insofar as hopnig that GloFo will gradually unfuck their process which will shift that wall forwards. So B and later steppings of the Ryzen should see more headroom through natural process improvements, yeh? I'd say you are correct on all accounts. If GloFo makes some additional headroom and AMD can push out Zen+ with slight IPC improvements next year, they'll be in a really good spot. In unrelated news multiple people are reporting that non-X processors feature XFR and I have no idea what that means. OCUK posted:All three processors are the same, they all have XFR technology. The X varients have higher boost clocks hence the X, otherwise all three CPU's feature XFR and the only difference is clock speeds. https://forums.overclockers.co.uk/threads/amd-zen-thread-inc-am4-apu-discussion.18665505/page-386#post-30531006 computerbase posted:No. The X has nothing at all to do with it and does not stand for XFR either.

it's so strange because what are they going to do with all the 8 core dies with 1-2 defective cores? put them in a pile and wait a few months before shipping them out? The only explaination I can come up with is that they have better yields than expected and decided to milk the early adopters. By the way the R1600X slide in that imgur gallery I linked earlier shows 6c/12T 3.6/4.0. I'm going to guess that it'll also clock higher because of the lower TDP.

FaustianQ posted:stuff Yeah that makes sense. The current 8C/16T model preorders have sold out before benchmarks are out so I guess they're doing it right. The fact that they (think that they) can ship vast such amounts of high end SKUs at launch leads me to believe that R3/R5 SKUs will have decent OC headroom from the start. A 4C/8T R1400X clocking to 4.6 Ghz for $199 would cannibalise a good amount of R7 sales at launch, so perhaps they're really sandbagging.

fishmech posted:Honestly you should wait until it's actually been out for a few months and motherboard manufacturers have had time to work out the ievitable bugs. this should be the new OP. If you really need a high end CPU right now for whatever reason, the R7 seems like a good option. All others should wait a few months to see how things shake out — motherboard stability, CPU errata, benchmarks to evaluate performance behaviour for your applications, GloFo process improvements, better value SKUs with more OC headroom, perhaps even a response from Intel (heh who am I kidding).

Elotana posted:i want to believe seems realistic considering the 6800k is a 3.4/3.6 Ghz Haswell 6-core. Ryzen should have similar IPC but higher clockspeeds with their XFR thing. The one I'm really looking forward to is 1700X/1800X vs 7700k both stock and OC. The CPU-Z benchmarks above show parity between a 1700X and a stock 7700k, if that's possible with custom watercooling then I'll be very tempted in 6-8 months even though I didn't plan to upgrade anytime soon.That probably was at ridiculous voltages and/or LN2 though...

Even if AMD doesn't follow up with Zen+ as early as next year, it's going to be interesting. Not to mention that Intel no longer has a GT4e SKU to counter a 50W Zen APU.

No Turbo. Here's a german guy trying to delid Ryzen CPUs, casually mentioning that he already killed two in the process. They're soldered by the way.

It's a really dumb move, AMD clearly has (soon had) the whole enthusiast community, including reviewers, rooting for them as the underdog that may not deliver 100% of the gaming performance but at least tries to change the desktop CPU landscape for the better. Now it increasingly looks like throwing it all away with BIOS "benchmark modes", strict last minute reviewing guides and whatever else. It's not like those additional few percent would have changed the buying decision of many people. The truth will come out either way.

Yeah the BIOS screenshot reports 1.4V for a 1700X with everything set to default. If that is true then the review samples with mediocre 4.1 GHz OCs were the best binned CPUs they could possibly find.  I find it remarkable that Ryzen does extremely well in most of the synthetic benchmarks but stinks in any unoptimised game - much more so than what the single thread synthetics would have us believe. That low res CS:GO score is worse than what a commenter posted of his Pentium G4560.

Disabling SMT in BF1 gives a stock 1800X the same performance as 1800X @ 3.9 Ghz and increases minimum framerates by 50%. "You're better off disabling SMT than overclocking, although if you do both you'll get more of an performance jump." Looks like their neural network threadripper still has some learning to do.

HalloKitty posted:It's close to what could have been expected, except I was surprised to see how badly it could perform with SMT (THREADRIPPER) enabled at times in the Gamers' Nexus review. Pretty much. Zen predominately seems to be a high IPC/low frequency design and it seems like they relied on the process to get the frequency up. Because relying on GloFo has worked so well in the past. A quadcore Zen @ 5.0 Ghz would have been very impressive but that was clearly not going to happen at lauch, so they launched it with twice the cores to hide the fact that it really isn't all that competitive compared to KL. I'm surprised that $AMD is holding up so well. I kind of expected /r/ayymd to panic sell. AMD is still in a decent position with Zen+, APUs and Naples. Not sure about mobile.

And we do exceptionally well in rendering and workstation applications where more cores are really useful. In 1080p, we have tested over 100+ titles in the labs…. And depending on the test conditions, we do better in some games and worse in others. We hear people on wanting to see improved 1080p performance and we fully expect that Ryzen performance in 1080p will only get better as developers get more time with “Zen”. We have over 300+ developers now working with "Zen" and several of the developers for Ashes of Singularity and Total Warhammer are actively optimizing now. well yeah my 6 year old CPU is also doing well when the applications are more graphics bound.
