Another review this time of the 8600k and 8400. 8600k beats the 7700k overall, and the 8400 is very competitive against the 7700k. Interesting to note he did a 2500k at the end of the review and it gets annihilated. So i think it's safe to say that the 2500k is past it's used by date for gamers (chuck in a 3770k though for a nice boost)

As a (soon to be ex) 2500K owner, I would have to agree. Its bottlenecking my R9 Fury which is just a mid range GPU by todays standards. Going to drop in a 2600K for a cheap upgrade, should tide me over until the supply issues with CFL are solved and DDR4 prices come down a bit (hopefully).

The 8600k is the real jewel of the lineup if you ask me. I would still buy the 8700k because I like the overkill, but the 8600k is sick for the money.
If you are building primarily a gaming rig, I would agree. The $100 saved can go towards a faster GPU, for example. For a multi purpose desktop PC though, my vote goes to the 8700K or even the 8700 non K, which is practically the same price as the 8600K with a decent HSF.

Why not go for the 3770k?

When did he say that (dual channel for SKL-X)?

He didn't, but AotS benchmarks shows it. Well his AotS benchmarks seems little off... It doesn't even matter since only few games has same optimization.

But here is interesting, i7 7820X has turbo of 4GHz all core... running at 4,4Ghz give i7 8700K at 4,7GHz only 4FPS advantage.

4,4GHz i7 7820X, i7 6900K, i7 5960X

vs

4,7GHz i7 8700K


Seems like GHz really helps to get few extra FPS, but you must have fast ram. Maybe we will have GHz and DDR4 war.

I'm guessing that post was for me? Sure, my motherboard can take a 3770K, but the asking price on these chips are way too high IMO. They sell for over $200 here (AUD, approx $160 USD) whereas I was able to get my 2600K for $120, or roughly $95 USD. There is only a small difference between Sandy Bridge and Ivy Bridge, not enough to justify paying almost double the price, especially for a 'stop gap' CPU that I'll only use for the next few months while waiting for CFL stock to increase and DDR4 prices to settle.

Ok I see. Over here in USA, on ebay, I was looking at both going for around $130 vs $180. Looks like you got a pretty good deal on the 2600k.

7820X also has 4 more threads than the 8700K.

Checked expected delivery dates and my heart sank at both the elusive board and 8700K. Aside from crazy prices the Apex shifted from this week to the last of October and the CPU from the week after to 28 November. These are still probably guesses by the site so reality is much worse. Getting frustrated here.

Is that on your order, or the published date for new orders? It's always important to distinguish the two, because as pre-orders stack up, if an expected shipment gets fully pre-sold, the expected date for new orders will get pushed to the next expected shipment, but existing orders aren't going to change. You'd still get yours out of the earlier shipment.

CFL should have launched in early 2018 after Intel had built a good volume for launch. 8700k is going to be hard to find in 2017. Anyway good luck on getting the 8700k as soon as possible.

There are arguments to be made for all the 6 core Coffee Lake CPUs.

Here the 8600K is $100 more than the 8400, and the 8400 is no slouch either, making the 8400 a very strong bang/buck contender.

Good point. Not my order as the dates come from the only shop that actually lists dates (the others just say: 10+ week days / 2017 / etc.). I have only pre-ordered the CPU, at another store, and they have no idea when they are getting any in to begin with. I would've pre-ordered the Apex too but my shop isn't even listing it yet. Worst Intel CPU launch since my time on earth :/

The 8th gen is comprised of a very strong line-up, the best so far if you ask me!

I can feel your frustration. Like I said before, I believe Santa is gonna be selling a lot of coffeelake chips. Hang in there.

Thanks

My fear is that availabiliy for the Netherlands will be pushed back to the original Q1: 2018, but even December is too late in my perspective (for a CPU that launched on 5 October). If Intel had ignored the hate which led them to bringing forward the launch and would've released it in Q1: 2018 so they've had the chance to built up inventory, because the zero availbility isn't helping them at all (although I do believe they are working as hard as they can). Moreover, I have several game titles (incoming/releasing soon) that benefit from this platform and thus I'm holding out playing them while they sit on my desk and I think that's where my 'issue' lies; not being able to play those games upon release after having looking forward to them for a few years. First world luxery problems eh?

Didn't mean to derail the thread, sorry guys!

ShopBLT (the only US retailer that has actually shared dates that they expect new stock to arrive as far as I know) has had no variance in in the date they expect more stock since they posted it. That is, they expect their CA warehouse to receive stock next Monday, and their other warehouses to get stock the Thursday after that. Now, if these dates are real, who knows, but they haven't changed.

I use an overview site that lists prices etc. for all webshops in the country and the one that shows dates has, to my knowledge, only popped up now alongside a few others, making me highly suspect of their authenticity - although the overview site does not list suspicious sites. Still, I'll wait for 'my' shop to place a(n) (pre-)order. I do expect US/China availability before the larger countries in Europe (let alone the smaller ones like mine) get some, or perhaps more stock.

From OCUK (UK): *WARNING: PRODUCT IN SEVERE CONSTRAINT, ETA NOVEMBER!* [8700K]
I think I'm just not gonna sit on this and do something else other than checking when and where and just forget about the whole thing until I get a shipped notification. Too much daily disappointment ha ha!

@RichUK How are your SA and VCIOO voltages, or did you (have to) tweak and lower them? What RAM are you using again?

Honestly, I think the 8600K is in an awkward spot price wise and apart from gamers I really can't see its value when compared to other products around its price range.

As I said earlier, it's basically the same price as the 8700 non k once you factor in the price of a HSF, but even when overclocked to 5GHz it is only 400MHz faster than the 1C turbo of the 8700. Sure, it will be 700MHz faster when all 6 cores are under load, but if you are actually doing something that is pegging all 6 cores at full load you may as well get the 8700 because it has HT, and in terms of MT throughput a 6C/12T @ 4.3GHz >>> 6C/6T @ 5GHz

I understand. I am, at this point, sitting on a ton of hardware with all sorts of water cooling bits arriving this week, but with no idea when I will actually be able to do the build. I can, at least, learn how to bend acrylic in the mean time and maybe get the loop ready. The GPU will be a pain because it is currently in one PC, so removing it for getting the tubing ready will be a pain if I want to keep using the other PC.

It's kind of a wash. You get get about 20% boost from HT in those specific cases., and you can run the 8600K 16% faster, so I bet it will be neck and neck on those highly parallel loads, but in gaming, but in many other most mixed loads the OC 8600K will likely be ahead.

Also how many i7-8700 are really going to use Intels crappy cooler, so I don't see that being that significant.

I am think of getting an 8400 and even at that lower power level, I am thinking of ditching the crappy Intel cooler.

That's what I'd do 65W + a nice cooler == quiet. Or a 35/45w version were I building something teeny, tiny.

The cooler is indeed crappy. It's not the loudest fan ever, but it's annoying at load, and doesn't cool very well either. Only the AMD Wraith/Spire are any good out of the stock fans both companies have ever provided (at least as far as I've been building PCs). I feel bad because I have a graveyard of unused stock Intel and AMD HSFs.

Got my Gigabyte Z370 Gaming 7 Motherboard Saturday evening from FED-EX. It is fricken awesome!! So much better then I could have imagined. I like to just sit and stare at it and imagine the finished build LOL. Now all I need is a CPU to finish it off.Also added another piece to up coming RIG, purchased a EVGA GTX 1060 6GB SC from B&H for $239 with free shipping After MIR .First time I ever ordered from there so hope they are reliable and hope this is a going to be a good GPU. I did a lot of research before making my purchase.My main want and need was lower power consumption with high performance. From the graphs Anandtech is showing on the Bench link on the front page, it basically uses less power that my rx480 used? I hope this is true.

Why do people always make the same assumption that you get a 100% linear perf scaling with increased clock ? This never happens, atleast in majority of apps. 8700 at 4.3 Ghz with HT will definitely be faster than 8600k at 5.0 Ghz for MT workloads. Proof : have a look at 8600k at 4.8 Ghz not even close to 8700k (8700 has the same all core turbo)
