Intel Core i7-8086K Listed, First 5.00 GHz Processor

May 30th, 2018 04:10 Discuss (103 Comments)

Intel is commemorating 40 years of its 8086 processor, the spiritual ancestor of the x86 machine architecture that rules modern computing, with a special edition socket LGA1151 processor, dubbed Core i7-8086K. The chip appears to feature a nominal clock speed of 4.00 GHz, with a maximum Turbo Boost frequency of 5.00 GHz, making it the first mainstream desktop processor from Intel to hit the 5.00 GHz mark, out of the box.

The Core i7-8086K is more likely to be based on a special bin of the 14 nm, 6-core/12-thread "Coffee Lake" silicon, rather than being something next-gen or 8-core. The retail SKU bears the part number "BX80684I78086K." The chip will be compatible with Intel 300-series chipset motherboards. Pre-launch listings put its price around $486, which is along expected lines, as it's 70-100 EUR pricier than the i7-8700K. Intel could unveil the Core i7-8086K at the 2018 Computex (specifically on the 8th of June), alongside the first motherboards based on its Z390 Express chipset.

I just caught the $486 pricetag...
Nice...
"8086"... first of the x86 line..."486".... Last of the x86 naming scheme.

8700K's can already run 5GHz on all cores. We just need a firmware editor.

buildzoidUm what about the FX 9590?

You're right, the FX 9590 was technically the first to have 5.0 GHz turbo clocks out of the box. But it had an original MSRP of $899.99, required liquid cooling, an expensive top-end motherboard, and a strong fan aimed at the VRM area of the board, to handle it's 220 watt TDP. It also had terrible single core performance. It now retails for $104, so I'm guessing they didn't sell that well. This 8086K should be much more practical, and will have top-of-the-chart single core performance.

I think this captures the whole scope of "consumer/average joe", just because it costs ~half of the 9590 (still ludicrous for an 8700) but it drops into a 300 series board with no issue. Call it 5GHz for the masses, it might not be the first but its relatively affordable.

If we're digging through memories, Cyrix actually had 5x86. I'm not sure if they also had a 6x86 after that.

But yes, the price of this one isn't randomly picked.

What a "useless" product. The last thing we need is a new i7 with even more aggressive boost.

Id very much consider it if it was more than 6c/12t

They did have a 6x86, and let's not forget the Am586.

More on topic, not sure why people are arguing that the FX-9590 doesn't count as the first 5GHz chip just because it was ridiculous and sucked pretty bad. And for the record it never cost anywhere near $899 in the retail channel, when it arrived at retail I believe it was around the $300 mark (originally OEM only). This chip is pretty cool nonetheless though.

the first mainstream binned chip for the masses, I guess.

bugIt's a tribute to a 40-year old CPU that ushered in the PC era. The $500 asking price is nothing, I expect this is worth a lot more to a select few collectors.

There's nothing special about the part that makes it collectable, other than the SKU on the cardboard box, meh. Hard pass if it's $500. Unless they slam 128MB cache on it, like the one chip (5775C? I forget.)

I never said it was expensive, I just don't see it as worth any 'extra' personally. If people want I can sell them old, low tier processors for $486 as a "tribute". See what I'm saying? I guess there's a market for it though...

I like the wishful thinking. Would make an absolutely perfect CPU for VR with the tightest possible frame times. However, you can probably tweak DDR4 now to reach nearly the latency and far surpass the bandwidth of Broadwell eDRAM. And then again, if eDRAM was to be redone today, its latency would probably reach sub 20ns, bordering on L3 cache territory.

lasMight get this chip just for the lols.
Imagine if it's not using pigeon poop (Devil's Canyon anyone..) - 5 GHz will be doable with cheap air cooling.

Yeah, sadly AMD's 5 GHz chip were (and is) insanely slow..

It will work just fine on Z370.
Z390 is what Z370 should have been from the start. Z370 is Z270 basicly..

You wouldn't be able to tell in real world.

Between 8 Core FX @ 5 GHz and 6C/12T CFL at 5 GHz? Yes, yes I would. Everyone would. Even a 2600K with OC would slam that old FX @ 5 GHz in pretty much everything, especially games.

FX series were (and is) terrible. Insane watt usage on top of that.

AMD CPU's first became relevant again with Ryzen. FX was a disaster.

mouacyk8700K's can already run 5GHz on all cores. We just need a firmware editor.

Not all. These will be better binned for sure, meaning higher overclocks in the end. Maybe they even comes with good TIM, like Devil's Canyon back in the day.

CrAsHnBuRnXpId very much consider it if it was more than 6c/12t

Yet you bought i5 with 6c/6t?
8c/16t would mean lower clocks, which is worse for games and most applications.

So what thermal interface material (TIM) Intel is using under this IHS, probably the same old 8700K "paste"!
Thanks for nothing...

That's an understatement for the 220 watt FX 9590.

lasBetween 8 Core FX @ 5 GHz and 6C/12T CFL at 5 GHz? Yes, yes I would.

Heck even the Ryzen R5 2600X at 4.1 GHz (133 watts maximum observed) would be noticable over any Piledriver at 5.0 GHz.

Probably not, because then very good cooling will be needed for that 5 GHz boost. Either better TIM or heavily binned chips.

Ryzen at 4.1 GHz would destroy that FX at 5 GHz for sure.

It's not that hard to bin for 5Ghz. I'm certain that's the route they've gone rather than solder. And they don't really seem to comprehend a better paste exists. They even ship the same brand dow corning shit with their heatsinks. I opened a rare tube of it once with one of their actual decent LGA1366 heatsinks and the stuff was dry as powdered Sahara sand... longevity my ass.

I think they called that Planned obsolescence. How many de-lid say 4-5 years of hard use to see what is under the IHS.

It's part of today's series that happened to match the 8000 moniker with a little binning and a witty choice of part number. For what it is (a trip down the memory lane), that's all that's needed.
Also, the 5775C had 6MB of cache, like most Broadwell i7s. What it did have, was 128MB of dedicated VRAM.

It was in a sealed tube. My point is it doesn't last under the best conditions, even.

I certainly can. How about we talk like big people here? You know, without the vague insults to "99" of our community?

The title is slightly misleading though.

bugdedicated VRAM.

eDRAM, technically. On die ram. That didn't have to be used as VRAM, and could be repurposed as an L4 cache.
