EVGA Also Teases Possible Z390 DARK Motherboard
It's been a busy past 48 hours at EVGA, with the launch of the B360 Micro motherboard, unveiling of the NVLink bridges, and now a teaser of what could very well be the company's Z390 DARK motherboard, targeted at professional overclockers. K|ngp|n shared this teaser image of the board on social media, revealing a socket LGA1151 motherboard that's laid out like an LN2 overclocker's dream - memory slots north of the CPU sockets, CPU VRM to its west and south, and power drawn from a combination of 24-pin ATX and two 8-pin EPS connectors angled away toward the east. A cluster of 7-segment LED displays put out diagnostic codes. The designers seem to have opted for an expensive 8~10-layer PCB that's rich in copper. We'll hear more about this beauty as the Z390 platform launches later this month.

I'm afraid EVGA wants the attention of extremist with this.
That mentioned - really really dig this design. This is how it should have been done for years now.
I'm using a Maximus 10 Apex and only a single 8-pin for CPU PWR and have ZERO stability issues until about 5.5Ghz - 5.6Ghz.
More likely the limitations of my Noctua air cooler, or my limited knowledge base, than the CPU power cables. lol :)
as in BLACK, everywhere, all over, under and around everything, including the CPU clamp arm and socket too....
Otherwise it might as well be called an "almost dark" design :D
"24-pin ATX and two 8-pin EPS connectors angled away toward the east"
Regardless, I'm concerned about low pin count socket taking that many amps through it's tiny pins (in short, I'm worried about Amps/pin with OC'ed 8 Core CPU).
In past, Quad Core CPUs simply weren't capable of requiring that many Amps (not since LGA 775, but that has bigger pins).
However, for socket desinged around Quad Core Skylake, they now release a OC capable Octa Core CPU ?
(old boards do support Octa core with UEFI update, right ?)
In terms of amps/pin I'm going to say it's a non-issue because I trust that Intel knows what their doing when it comes to CPU's. :)
And yes, it can work on older boards. I know the 8-core works fine on the Z170M OCF though we'll have to wait and see if Nick decides to publicly provide an updated bios for it.
even if a single 8 pin can handle that, there will be a huge difference in ripple than using two 8 pin connectors that will effect stability.
i can't count how many times people complained about their graphics card getting flaky gaming/benchmarking until they used two cables instead on one w/daisy chained connectors.
now you know.
yeah my napkin math isn't perfect but it's close enough for government work.
However, here's the limitation of "TDP" rating...
Please explain to me, how a Hex Core CPU and Octa Core CPU can pull the same ammount of power, when they are made using the same technology/architecture ?
Also, I'm worried about sockets being damaged after Octa Core OC, because of too high Amps per pin IN THE SOCKET (NOT on EPS connector).
TDP has nothing to do with the amount of power a component will use, it is rather used to determine the required level of cooling required for it to function at stock frequencies and voltages under normal workloads.
When compared stock vs. stock the 8-core will most likely use more power than the 6-core yet may not require a higher capacity heatsink to function below it's TjMax in normal workloads.
Basically TDP doesn't really mean anything to the end user and should not really be used to compare CPU's.
and the TDP is simple; intel cheats. they pick an arbitrary number to make themselves look good. for one generation they may consider voltage at base clock for TDP and another voltage at all core boost clock. though it's more of an efficiency number, it is correlated to power consumption; because it has to consume power to produce heat; physics!.
like i said before; close enough for government work. ;)
seriously, i showed you it isn't a concern, HWBOT is loaded with folks pushing those sockets w/o any problems. i mean, you don't seem to wanting to push it that far, so why the concern?
let the folks who are worry about that. :)
E: and again there will be less ripple in the power going to the VRMS/socket/chip with two connectors than w/one. <- the BIG reason!
Not so sure about the naked legs on these connectors though.Regarding generational changes - so does everyone else. It is not so much Intel cheating than motherboard manufacturers cheating (WTF is MCE and friends?) and nobody reading the documentation. Intel has very good documentation on what is what and how power management works.
so yes, you can unknowing think they are providing information when in fact it is little to go on. don't try this, "oh it's there, people don't know how to read bullcrap."

Regarding tables, for example 8700K is 6-Core GT2 95W.
Their test conditions do not actually account for the load. Both control as well as testing is based on power sensors (and thermal sensors which should not be a problem given adequate cooling solution).
since you have proved what i said yourself, we are done here. good talk.
Desktop CPUs are very well optimized to the TDP points so that TDP is not severely restricting performance. Low-power (45W, 35W) and mobile chips are where TDP restriction becomes very noticeable.
Intel says chip vendors' TDP figures are not comparableso you have it backwards, the cpu isn't very well optimized for the TDP but the TDP is adjusted for the cpu. this has been pointed out for over 11 years, since conroe, that i am aware of and some googling will show even further back than that. so what ever you say or think is not going to change history.
i am now out of time and any desire to continue this discussion here.
have a good day.
