The one time AMD actually sets prices that are almost *reasonable* compared to Intel.... and they gotta kill me by doing poo poo like maybe including AIOs with certain Threadripper SKUs. http://www.guru3d.com/news-story/amd-threadripper-might-get-aio-lcs-liquid-cooling-bundled.html

PerrineClostermann posted:But I want to build a custom loop! Then build a custom loop? But seriously, it'd mainly be attractive because it'd be a stock cooler. There would be no need to worry about getting the right fixtures to fit an already on the market AIO or pump to the CPU and you should get pretty good cooling. And if you don't want it you could just not use it (or perhaps buy one without it maybe?).

That is a hell of a lot better than the "stock cooler" for Intel high end chips being both a price-gouged Asetek AIO and a completely separate purchase from the chip itself.

I wonder if the rad fits to the top 120mm slot on a silverstone raven 02: http://www.silverstonetek.com/raven/images/products/rv02/rv02b-inside.jpg If yes, I could see myself actually using a watercooled setup for the first time in my life. I don't want to buy an expensive $150+ case just to fit an AIO though.

Munkeymon posted:Pretty stark difference in some of them. I'm guessing Witcher is very single-threaded? IMO it's more of a memory problem, there's very clear memory scaling even on Skylake/Kaby Lake. On the whole W3 is actually pretty good about spreading across cores but there's no question that cities run noticeably worse, for everyone. Particularly Novigrad, the biggest city. I don't know if anyone's ever sat down and done the science to determine the exact behavior and mitigations (more RAM, more bandwidth, lower latency, etc).

So I was watching Hardware Unboxed (really good tech channel IMHO), and they did one on whether the Mesh clock was holding back Skylake-X performance. It's not, but in the comment section this came upquote:It's actually worse than Zen (I'll explain) L3 design, but Intel is making up for it with brute clocks & larger L2. L3 typically have more cycles (slower latency vs L2 access), on Zen, AMD makes up for this by making it both large and shared with the other cores in the CCX. It's not 2MB per core, it's 8MB per 4 cores, all shared with enough associations for parallel read/write cycles. Sounds like Intel hosed up Skylake X L3 design and AMD might come away with the better overall scalable solution even without considering MCM. It's not Netburst bad but if Intel continues to push the mesh style uarchs which seem to regress performance they may put AMD in a position to pull another Athlon XP/64 again. Gaming desktop performance might not be a large market (or to say, it is, but it's a small market within context of the semiconductor industry) but it's a very loud, public section of the market, and one that is easy for a layman to get. https://www.youtube.com/watch?v=mTQ6ymQIY64

Unimpressive gaming performance by SkylakeX definitely gives TR and 8C16T Ryzen in general an edge they wouldn't have had otherwise but probably not a decisive one in of itself. I think its when you combine that issue with some of the other X299 platform SNAFU's + higher pricing that Intel is demanding for Skylake X that TR and 8C16T Ryzen starts to look like the way to go. I'm sure some will still buy Intel no matter what though. After all even Netburst was a solid seller for Intel!

Based on the benchmarks and videos I've seen so far the Intel Ringbus CPUs are their best chips for gaming and probably will be until at least Ice Lake. X299 isn't terrible but they shouldn't have marketed it for gaming. The Intel CEO himself said something along the lines of "get a 18 core i9 for high resolution gaming". Truth is that the 7700K continues to run circles around these high core count, low frequency parts and Coffee Lake should do even better. The 7920X just leaked today with +2 cores and -400 Mhz compared to the 7900X.  AMD is in an excellent position if they can squeeze more frequency/IPC out of Zen+.

I mean yeah it sounds pretty drat smart on the surface but as has been pointed out, it really doesn't seem to do anything for HPC either as EPYC is able to come in at better performance most of the time with equal or 20% better power draw, and is 50% the price or even 25% the price depending on dual or single socket configuration. It also means that for the foreseeable future, AMD is the better choice for HEDT (what AMD calls SHED, and I feel like there is a joke here) and that is not a sentence I'd thought I'd ever commit to writing.

eames posted:AMD is in an excellent position if they can squeeze more frequency/IPC out of Zen+. At that point it'll come down to how many chips GF, or pooooooooooooooossssibly Samsung I guess too, can fab up for them. AMD was always fab constrained in the past when they had a competitive architecture, I think for the longest time (even going back to the K6 era) the best they could supply was around 30% of the world's x86 demand (the Dresden fab was supposed to allow them to supply around 50%+ x86 demand initially but then multicore started to take off which blew up die sizes and that was that...), which guaranteed Intel to be able to still sell a heap of chips no matter what. If after going fabless, and after all the poo poo they've been through, they end up being able to really meet a majority of x86 CPU demand for once in their history I'm gonna laugh and laugh and laugh.

5Ghz? Anything around 4.5Ghz with Zen+ will close the casket on Intel's gaming dominance.

I'd be happy if the fabric ran full speed asynchronously, it could run ddr4@3600 easily and it hit 4.2ghz stock easily at the same wattage as stock does now.

Another Ryzen memory performance comparison. http://translate.google.com/translate?u=https%3A//www.computerbase.de/2017-07/core-i-ryzen-ddr4-ram-benchmark/2/&hl=en&langpair=auto Their conclusion for gaming is that a 1600X with DDR4-3200 is faster on average than a 1800X with DDR4-2666 and clockspeed is more important than timings.

I dunno, Zen2 could blow everyones labia off, but this is Keller-less AMD on an internal Glofo node were talking about. It's also not going to be on shelves until late 2018/2019, which means its theoretically gonna be facing 10nm Cannon Lake/Ice Lake from intel, a process which took them 3 years longer than they expected to develop. Hard to say what any of this stuff means yet.

Seamonster posted:So is zen+ the die shrink? Or is that zen2? Zen2 is what AMD is now calling what used to be Zen+ on their slides. The 14nm+ version of Zen doesn't have a specific code name that I've seen, and I don't think they are expecting too much of a performance boost.

Combat Pretzel posted:14nm+ for H1 2018 or what? Yea, Pinnacle Ridge apparently. My understanding is 14nm Plus is the LPP process with modifications requested by AMD, much like the 12nm process from TSMC for Nvidia. Considering their roadmap for 2018 has Polaris and Vega on it, I'm expecting yet another refresh for the GPUs on this process as well. All I can say is gl AMD.

What sort of clock bump can be expect from LPP? 4GHz base on the top end CPUs would be nice. Or 3.7-3.8GHz on the top end Threadripper.

Or 3.7-3.8GHz on the top end Threadripper. 14nm LPP is a mobile focused process that doesn't seem to handle large die, high density design well so I don't expect better clocks but rather better perf/watt at current clocks. If you want 4Ghz base I'd be eyeing Zen2.

If I remember correctly Jim Keller designed Zen and one improved version of it for AMD. I would hope that Zen+ is simply a die shrink and Zen 2 is that second design.

Zen+ and Zen2 are the same thing. Its a branding mix up for a unreleased product so its irritating but doesn't actually matter since almost no one but us and a few other industry types even looks at AMD presentation slides.

Cygni posted:A theoretical 8 core TR would be 2/2+2/2. You could also do a comical 4 core with 1/1+1/1, which would join the Epyc 7251 8 core (1/1+1/1+1/1+1/1) in "this is for a very specific use case" territory, ha. Lots of cache/memory bandwidth, lots of PCIe, not a lot of raw proc power. So, ARMA gaming rig?
