I love how this thread went from a question about what clock speed do you think the coffee lake will ship at to over 80 pages of stock tracking and discussions about everything else lol... I am just as much a part of the fun.

Good to know, thanks! I already did my build with i3 and overclocked to 5ghz, so it is destroying games with my 1080 ti but the real reason I built the computer was for audio virtual instrument live playing at low latency. My apps take advantage of multithreading so I really need the additional cores. Looking forward to that 8700k.

If you’re not in a super hurry, you can preorder one from B&H for around $390. I had one preordered and then got one from Newegg - I seriously considered flipping the one from Newegg and keeping the B&H order, but I got too excited when I saw the 8700k box and decided to keep it and cancel my B&H preorder.

Does VRM temps cause throttling? What would cause a CPU to drop freqs like that on prime 95?
Click to expand...

Yes it does throttle if the temps get to high on the VRM. Temps above 120 on the VRM for extended periods will cause them to fail at some point.

7820x on stock settings does 178, not 147. I guess OCC3D used a beta BIOS with turbo disabled or something. SKL-X @4.4GHz does 196. So at 4.8GHz it would do: 196 * 4.8 / 4.4 = 213.81, and TahoeDust got 214cb @4.8GHz

im starting to really wondering if ryzen's ipc is low like around ivy. because of infinity fabric issue with their ram which result in much higher latency than within 1 ccx itself such as pcper shown. CB15 reflect higher score with faster ram and amd's system here gets penalized heavily on it, so CB15 would not be an accurate indication to actual IPC as ram is outside of CPU architecture. however thats also the sad part CPU does have that infinity fabric and it is dependent on ram speed.

if upcoming rework on the architecture of infinity fabric, we might really see ryzen's core true IPC. makes you wonder when AMD claim 52% over excavator was it CB15 score comparison, or latency comparison.
 
I am getting 193 single core on my 7820x at 4.6*4 4.3*2 & 4.2*2.

I think that is impressive given my 8600k got a 198 at 5.0.
 
Just a heads up: after doing a lot of tuning Im going to absolutely not recommend the 8700/8700K for anyone using the L9i or similar. Even manually limiting the mainboard TDP still results in 100C in BF1. Even with a far more powerful fan, the system still hits 90c.

These chips run much hotter than they 65 and 95 watt quad core predecessors.
 
SL has a concrete date of November 11th for their binned delids.
I recommend using Distill if you're waiting to grab one.

My 4770, even though being rated at 84W, typically uses up to 130W while gaming in stock condition.

They run the same temperature at the same clock speeds as the old chips but the caveat is the lack of solder like the old chips, so they can't dissipate the heat faster than it builds up.. It is just now you are pushing the thing to 5ghz and beyond so its pulling at least 150 watts. And that tiny little IHS, having no thermal inertia, needs something with a large thermal capacity to soak it up. That little air cooler doesn't have the thermal capacity to dissipate that much wattage.

I think that it is pathetic I have to delid my 7820x but alas I will soon. Such a shame a chip like that must be modified so that it actually performs under pressure as it was supposed to have been designed to do.

Trying to run either of those with that dinky cooler is just dumb in my opinion.

He only got 100, the prices could be jacked sky high and they'd still sell out.
Not optimistic.

from overclock forum they got around 165 people voted for wanting a binned 8700k, so at most i'd say 200 is what they need. imo their pricing will be based on the percentage chips they tested out of that 100 chips they've got, i'd be willing to pay for $700 for a really binned chip say 5.3-5.4ghz
 
With how limited supplies seem to be with these chips. I'm guessing Silicon Lottery is going to charge closer to a grand.

The lowest bin will be in "the lower 400's" according to the forums.
Not that bad considering current retail is $420. Although I would rather buy a stock chip than SL's lowest bin.

thats quite high, cause i could get 10c cpu with it instead i honestly dont think they'll charge that high even with low on stocks as they already mentioned its by % of how many chips can hit, well assuming they keep to what they said.

$700 prob sounds reasonable, though i dont mind $800 for a superb highly binned but that depends on voltage and the frequency. 5.4ghz for 1.5v? i'd not buy it for $800, but 5.4ghz for say 1.45v i'd probably buy. if its 1.4v for 5.4ghz i'd definitely buy.

8700K has been instock at Newegg for about an hour.

for a target of 4.8ghz is plenty enough for most, i'd ask them to go retail.
i wanna get my hand on a 5.3 or 5.4 tho.
have had only mediocre cpus for years want something for a change
 
Going to try my hand at overclocking my 8700k this weekend. Haven't overclocked since my 3770k. I set it and forgot about it years ago. I'm seeing "uncore" and "avx" and 5.0ghz on "all" cores. All foreign to me. Excuse my UN-hardness.

Can someone please point me in the right direction for guides to read? Can I just research 7700k overclocking methods?
 
Over MSRP, sure- but stock means that their shipments to retailers are exceeding demand, which means competition will set in and start to adjust prices back toward MSRP,.
 
These multi-month long stretches of popular parts going for well over MSRP is changing the landscape for determining "value." I had to order an 8600k to replace someone's very old i7 game rig that lost a MB. The freakin CPU was $300. It's the same price as a Ryzen 1700. Had to talk to them for quite a while to cover the differences and decide on which one. But any way you slice it, that's a spendy i5. Within $40 of what I spent on my i7-7700k when it was new. And this i5 has theoretically been launched for over a month.

the problem is with mesh though, 2400mhz and prob only hit like 3300mhz highest ive seen so far. if it can do like 4000mhz or higher i'd go for it.

Yeah if SKLX had proportional game performance to the 8700K I'd probably be able to justify getting one. That + solder and I'd definitely be in.

The 7800X benchmarks were a big disappointment, at least the 7820X+ have extra cores. Intel is really dangling the carrot.

You know the 8600k beats the 7700k by a hair, so if it's $40 cheaper then they got a deal or you paid too much
