Fanboys are a pestilence.
AMD's fanboys unfortunately are more ignorant, toxic and feeble-minded than all of the rest combined.
Sad to see that this site has gone down the drain as well.
Goodbye.
Given that less than a third of 2700X can reach even 4.2GHz, picking up a 2700X and running it at stock is the best outcome overall.
That way you have ~4.05GHz all core frequency and around 4.3GHz single core frequency.

Oh, I agree.
NUMA does not belong to desktop or consumer systems.
Nevertheless, Threadripper is marketed as a consumer CPU.
Back in the day, Windows 7 received a hotfix to improve the suboptimal handling of BD compute units.
What's changed?
So basically you are saying that Microsoft would be refusing to fix an obvious bug in their OS, pointed out by AMD?
Makes perfect sense, especially when AMD hasn't made any statements regarding to it.
0:40 "And its not AMD's fault".
An issue of this magnitude remains unfixed / undetected for 5 months+, whos fault exactly it is if not AMDs?
Its GROSS incompetence (if accurate).
Its been remarked (laser).
SKL-X heatspreaders do not have the hole and the shape of the heatspreader doesn't match either.
If I had to guess, I'd say it is some early Broadwell-EP ES which has been remarked.
AMD has been tweaking the power management on Pinnacle Ridge CPUs after the launch.
Certain SMU FW versions released soon after the launch went a bit too far, and the deployment resulted in slight reduction in performance as well.
Several versions have been released since and more fine tuning...
CPU Core/Cache Current Limit Max = 255.75, Long Duration Package Power Limit = 4095, Short Duration Package Power Limit = 4095?
If it is throttling with those settings, then it is due to CPU or VRM overheating.
The most recent X265 encoder gains 43.5% of performance from its AVX2 implementation.
Zen lacks the resources required to execute the code at the same rate as Haswell and newer Intel designs.
Zen 2 will address that, for the AVX2 part. X265 also has some AVX512 optimizations, which improve the...
As Tuna-Fish already said, the two slots of the same channel (e.g. A0 & A1 / B0 & B1) are sharing the signals.
The configuration is called as "2 DPC" (2 DIMMs per Channel) configuration. Designs which lack the second slot (i.e. 1 DPC) for each of the channels are possible, and are usually used...
No.
The intensity (power dissipation per area) is just too high.
The same exact effect can already be observed on Pinnacle Ridge CPUs, which have significantly lower intensity (due to larger die size).
Yes, AM4 uses two main planes.
However, Carrizo was originally designed for three planes (VDDCR_CPU, VDDCR_NB and VDDCR_GFX).
The VDDCR_NB is pretty much constant and stays at ~ 1.000V+.
Meanwhile the VDDCR_GFX goes down to 0.800V at low performance states.
Since you cannot reduce VDDCR_NB that...
If they indeed support Carrizo APUs, then power efficiency has been sacrificed even further (the nominal IGP VddMin < than NB VddMin).
Carrizo is a three plane design, whereas FM2+ only supports two planes.
However, AMD has effectively returned back to two plane designs since (Raven).
There will be a significant delta, but I don't think the difference will be that drastic.
Dual rank modules can do > 4000MHz on this board, so being 1 DPC is not much of an issue.
And if 32GB is not enough, you can get dual capacity DIMMs for 64GB memory config.
The memory overclocking seems decent.
1.300V SA, 1.200V IO.
4500MHz itself should be doable, but not at these timings (DIMM limitation, too high voltage).
I'd say 5GHz in normal workloads and =< 4.8GHz in heavy 256-bit workloads is pretty close to the maximum, thermally wise.
Makes basically no difference if you're using a higher-end air cooler or 240 - 360mm AIO.
At those clocks you'll need a motherboard with a proper VRM as well.
In addition to PL2 and Tau1 many motherboard vendors modify IccMax (current limit) as well.
In some cases (e.g. 256-bit workload) the IccMax limit is reached before the (raised) PL2 limit, and that results in clock reduction.
I haven't tested different Tau values too extensively, but it seems...
"DTS2" (IRI) is a custom tool I've made specifically for ASUS boards (for my own testing purposes). It cannot be released to public because it contains confidential information of three different parties (ASUS, Intel and a third manufacturer).
Based on my experience, the Intel SVID telemetry...
The limits do not affect the maximum frequencies.
They can be lower than the maximum, but not higher.
Even if you run 2700X with LN2 and disable all of the power / current limits, it will not boost higher than e.g. 4.35GHz for the best two cores of the CPU.
4.35GHz for the best two cores of...
Based on my testing on several samples, the typical maximum all-core frequency on a 2700X is around 4.05GHz.
The variation is 3.975GHz - 4.075GHz, depending on the specimen.
The power figures stated in the review seem pretty funky to me, as a "package power".
As a whole system power draw it is plausible, but not as the consumption of the CPU alone.
Pov-Ray 3.7.1 b9 with "pvengine64 /benchmark" command.
The power limits, voltages and the overall behavior were set...
Excel supposedly uses AVX, but I'm not certain if its 256-bit or not.
Impossible to say about math as it is highly application / library specific, but possibly.
I'd imagine they come from the different motherboards and the different methods used to measure the power consumption.
According to Intel specs these CPUs should have PL2 set to PL1 * 1.25 (== 119W), not 210W like some motherboards configure them.
I've already mapped the minimum V/F curve for this chip in the past, but I added 25mV margin (1.070 >> 1.095V) for 24/7 reliability for this one.
~105W average in non-256b workloads.
The reported power consumption in several reviews seems to be extremely high.
Based on my testing, the CPU consumes at 4.7GHz around 128W in typical non-256b workloads, such as CB15 nT.
Which is within a watt of what the 2700X consumes at stock in the same test.
256-bit workloads obviously are...
Personally I couldn't care less what kind of average IPC improvement Zen 2 might, or might not provide.
What I need to see is a wider design, which is no longer handicapped in 256-bit workloads. In addition to that, the memory controller IP used in Zen and Zen+ has to go.
Being limited to =<...
High temperatures are to be expected despite the use of sTIM, due to the extremely high intensity.
Even Pinnacle Ridge CPUs suffer from this to certain extent, despite having a significantly larger die.
Not a surprise really, as to me it seems HWUB has become pretty openly a pro AMD site, more or less recently.
Basically they complained that Ryzen's memory was not overclocked nor the timings weren't optimized manually, and stock speeds and timings were used instead.
All of the systems were...
