Intel to launch 6 core Coffee Lake-S CPUs & Z370 chipset 5 October 2017
- Thread starter AthlonXP1800
- Start date
?
Yeah, the i5-8400 at £175.73, looks like a decent competitor to the R5 1600, shame about the lack of low end chipset boards to go with it.
Well the good news I guess is that it looks like release prices are the same as the 7000 series.
However, leaked benchmarks make it seem like the IPC has made zero improvement, maybe even regressed a little (considering it is supposed to have a 4.7GHz single core boost..). That is a shame.

Yeah, 1700 looks better for me now, but I'll see how everything is around Christmas which is probably when I'll be upgrading.
I found this...
Manufacturer Intel AMD
Model i7-8700K i7-8700 i5-8400 i7-7700K R7 1700X R7 1700
Single-Core Score 5,541 5,539 4,991 5,733 4,071 3,891
So the 8700K is slower in single core performance than the 7700K

That's what I would do, get the best overall package at the time you are buying.
Yeah I'd be very interested in that. If I upgrade from my 2500k I'll be needing new RAM to go with it. Would love to know the impact on CPU heavy games different RAM speeds have - all the way from the 2133 kits to the 4266+ kits.
I did a comparison vs my 1700 @ 3.8 with 3466CL14 ram.
Overclock that 8700k to 4.5 on all cores and this will be beating ryzen in multi too. (In geekbench at least)

There is little doubt left as to whether to upgrade to Caffelake or not:
-same crappy paste
-requires Z370
-zero improvement

Interestingly, the 8700k leaked bench seems to have a very low memory score compared to comparable 7700k benches (for the single thread bench). Perhaps the leaked bench is with very slow memory or something.
Thanks, just to note it's more around the point of diminishing returns on gaming/editing, you probably have already got this but just in case...

So from what i can gather is the following roughly true
8700k is going to require a new Z370 Motherboard, which will only last for the 8th Gen chips
8700K is slightly slower in Multicore than the Ryzen 8 cores
8700K is about the same speed as the 7700K in single threaded apps
8700K is going to be priced slightly higher than the 7700K at launch
It sounds a bit naff with the life cycle of the motherboard, but it seems you will be getting the best of both worlds, you will get Ryzens 8 core multithreaded performance pretty much and also the 7700K single threaded performance pretty much, while some will whine that the single threaded performance has not really progressed, the multithreaded perf will be much better than the existing i7's.
Do we think memory scaling will matter that much? im not convinced it will as its not same type of arch as Zen / Skylake-X etc that really benefits from fast ram.
Thoughts?
Personally i was all set to buy Ryzen, i have all the bits i need except CPU, i was going to donate my 4770k to the kids, but it seems the kids will be getting a 6 core Ryzen build now and i will just donate this 4770k rig to my nephew, looks like im buying an 8700k.

I wouldn't recommend trusting geekbench scores, they seem to unreliable. for example, it scored threadripper having worst multi-threaded performance than Ryzen 7.
I think that's why he said, in Geekbench at least. It is one of the less balanced benchmarks, and it's not something I would ever solely base a decision on, it's almost as bad as using just PC Mark. This thread would be barren without small bits of information, even if they aren't always hugely reliable once it is finally released.
Speaking of releases, it looks like the 8350K is going to be about £175, so basically they have reduced the i5 7600K, down by £50
You sometimes need to take a balanced viewpoint, and understand that not everyone is out for the ultimate performance, but a good balance of price to performance. I think that for gaming there will be no denying that Intel still holds the crown, especially at lower resolutions/high refresh rate, and if that is your primary and only concern and you have the budget, an 8600K or 8700K will be the best path if you can afford it, and if you balance your graphics solution well.
If you are buying, lets say a GTX 1070, then pairing it with an 8600K/Z370 (low £400's) board because that fits your budget, and you have a 1440P monitor, then the obvious alternative is the R5 1600/B350/X370 (low £300's) with a GTX 1080, both systems will cost around the same, but you will end up with a better gaming experience on the Ryzen system. However if you have a GTX 1080 TI already, and want to play at 1080p 165Hz, then the 8600K/8700K would be the route to go.
Ultimately there is no longer a one size fits all solution, and people banging on about one being better than the other, it is all relevant to an "individual" situation, and therefore should not be stated otherwise. So in some instances, it may not be worth it, in others it will.
Kind of agree. You wonder what people expect banging on about ipc increases. Why would Intel bother when they're already ahead with no alternative. It seems like performance will be very good.
Performance will be excellent, I'm sure, but it seems to me that the concerns raised in this thread are legitimate. It's more expensive than the i7-7700K, it probably won't clock as high, it still requires delidding and/or expensive cooling to get a decent overclock, and it requires yet another new motherboard. I'm sure you'll say you don't care and that but others do. Even if you think it's the best thing out there, that doesn't mean there can't be negatives about it.
