    Who's buying Skylake-X? (You may now change your vote)

    Well, you seriously claimed that 1800X would OC to 4.3Ghz, so i guess it does. Wait, it does not? I guess you really need that knowledge, then. Does not work that way, sadly, AVX stability and non-AVX stability are apples and oranges. So, just fire up both AVX and non-AVX versions of prime for...

    Intel Skylake / Kaby Lake

    Uh, they will in spec. The issue arises when you do anything related to overclocking. Possible, but as was said, they are still fine for running stock, just hilariously bad for any OC. It's not Panic, it's Chaos. We've first seen it with renaming of Skylake refresh as Kaby Lake.

    Yes, it has 2.7Ghz base clock and 3.4Ghz all core turbo as you mentioned, doesn't it? But as it is, Intel will set clocks exactly high enough for it to beat TR in AMD's benchmark of choice, that's pretty straight forward. That's a curious case and it all comes down to this question: why does...

    Intel Skylake / Kaby Lake

    Evidently it is not an issue at all since Intel used TIM on their highest TDP chips for last 3 or something years. I guess public really does not care about temperatures... not too surprising either. Yes, it is, but while you're correct that $25M is not very significant in the face of billions...

    Unlocked CPUs ignore power limits. Oh please, it will take more than that for any quality X299 board VRM to explode.

    Last time i checked we were talking highest end SKU. Intel's highest end desktop SKU was a 3Ghz base clock since Haswell-E. Well, that's another good point about power consumption: thermals. Got me thinking, both AMD for Vega and Intel for SKL-X outright claimed they are to be used with liquid...

    Intel Skylake / Kaby Lake

    Now consider for a second how many people will seriously not purchase a given CPU because it did not have solder. Seriously. I would be very surprised if it added up to even 100000 total. In the end, even with bad press and all, it's clearly the profitable move for Intel.

    Yes, their marketing does care to be the first, the largest, the newest et cetera et cetera. But the important part for them is to formally satisfy those adjectives, for money and ego. Providing product an enthusiast would value in every regard is not even on the list. Technically 18 core part...

    Exactly, what are you doing in this thread? It's not, Ryzen stack has set similar record before. In Ryzen's case inferior perf/watt costs more money though. Intel. Does. Not. Care. About. Enthusiasts. I don't know why i have to repeat it every time everyone pretends to be baffled about Intel...

    Kentsfield is different. If you want that story, look up magny cours. Precisely: Core 2 did not have IMC, you had 1 memory controller for every core even if you put 4 dies on a package. (or rather 2 packages with 2 dies, see Skulltrail). At what clocks? Go, try and guess the clocks, i'll wait.

    Who's buying Skylake-X? (You may now change your vote)

    6950X had 3.5Ghz Turbo 2.0 single core and 3.3Ghz all core, last time i checked. That fits perfectly with what i expect 7980X to have, you know. Because it has more throughput on 7900X. AVX512 and AVX2 should use similar amounts of power on 7820X/7800X for example. And yeah, since uncore is...

    Who's buying Skylake-X? (You may now change your vote)

    Once again, Intel had a semi-custom 20C 200W TDP SKU with 3.2Ghz base clock. Since SKL-X visibly has better voltage/freq curve than BDW-E, i would be very surprised if they did not manage to fit 18C 3-3.2Ghz (their typical base clock for highest end SKU in the past) into 165W, especially with...

    Intel already got away with 2679v4, 470ish (or whatever BDW 24c die was) sq.mm. 200W TDP CPU in this package, so Intel are hardly crazy. Now, Intel may be crazy if they think they will get away with bad assembly process they look to repeat once again on these. Why would they be reflected? I...

    The Ryzen "ThreadRipper"... 16 cores of awesome

    1. Average package power is irrelevant on desktop, Intel's TDP for HEDT is specified for "maximum" *stock* package power. 2. CPU-Z nicely reports 4.3Ghz and hwinfo reports load on all 10 cores. The only way this happens? Multi core enhancement. And since i have seen too many reviews that...

    The Ryzen "ThreadRipper"... 16 cores of awesome

    It's overclocked though, MCE [that Guru3D clearly have on as you see] is an overclock, after all. As for whether temperature is a problem or not, none of us know.

    AMD EPYC Server Processor Thread - EPYC 7000 series specs and performance leaked

    Here's what you forget: AMD did optimized SPEC runs anyways, and they beat Intel with a solid margin anyways. Hell, they didn't even use their patched LLVM for it, they used their own compiler that only supported bulldozer for it. I am not kidding, look at it...

    AMD EPYC Server Processor Thread - EPYC 7000 series specs and performance leaked

    Uhm, since when is 2/3rds of the die are CCXs? Die size is ~195mm^2, 2 CCXs total 88mm^2. Unless i've been missing on something, 195*2/3=130, if anything 2/3rds of the die are L3+non-CCX parts. Similar with split. Of course in the end it does not quite matter in this math because it is a...

    AMD EPYC Server Processor Thread - EPYC 7000 series specs and performance leaked

    Oh, make no mistake, that design is probably the best trade-off between yields, development cost and performance AMD could theoretically have. But there's a difference between praise and making up BS for the sake of praise. I take issue with latter. Anyways, only thing remaining to learn is...

    AMD EPYC Server Processor Thread - EPYC 7000 series specs and performance leaked

    So, yields are good enough that only 0.1% of all dies have defects in uncore that is around 100mm^2 in size and constitutes about 40% of wafer? Fott delivers premium information as usual. Thanks, btw.

    AMD EPYC Server Processor Thread - EPYC 7000 series specs and performance leaked

    Because in regards to Intel threads, P4 was not relevant since at the worst Nehalem. What is related is the fact that OEMs offered Bulldozer systems, just like they offer EPYC systems now. As such, talking about OEM offering products as stamp of product quality is a fallacy. Come on man, you're...

    Did you miss the part where i have repeated twice that OEMs including Microsoft offer Bulldozer systems too? Fine, i have just repeated it the third time.

    AMD EPYC Server Processor Thread - EPYC 7000 series specs and performance leaked

    Said they are offering it for customers, that's important distinction, just in case. Similar with 1n1 from my perspective. Samsung left me confused because most of it sounded like them promoting their memory and (subtly) process (cough-cough), but it'll do cause I/O and memory capability is a...

    Intel Skylake / Kaby Lake

    If you paid attention in the past you would notice that Intel either counts it's transistors differently, lies about density or does something very strange with design of their chips. Because their transistor counts are consistently and significantly lower than what AMD claims for it's own CPUs...

    If it was, it was not Intel's complaint/excuse. I personally am still keen on opinion that Ryzen is a hypervisor CPU first and foremost. EDIT: Oh, i missed it, but there were some binary benchmarks run as well. https://www.heise.de/newsticker/meldung/AMD-Epyc-legt-los-3748615.html So, we can...

    That sounds like explicit suggestion to use icc with Naples instead of multiplying Intel result by arbitrary number, frankly. Especially since we do know that icc generates perfectly okay code for Ryzen. I'll just mention that Geekbench 4 uses LLVM for all platforms.

    Well, they did say they were estimates, not actual numbers :p.

Though looking at how magically results (on Naples) for GCC -O2 are higher than every other...

    Intel "mesh" vs intel "Ring"

    Uncore is not really tied to memory clock on Intel CPUs.
  39. L

    Intel Skylake / Kaby Lake

    The issue was the fact that you had to add a second ring and buffer between them. That increased latency well over twofold. Now the highest latency on XCC won't go higher than ~160% of highest LCC one if my napkin math is correct.
  40. L

    Intel Skylake / Kaby Lake

    The idea here is that while it is worse on LCC, it scales way better than ring bus with core count. Also, latency is higher, but so is bandwidth.
