I mean the base clock alone is higher than most Ryzen CPUs overclocked I believe, and you have the extra cores also so what do you really want?

Time to redesign the age old pc case into a mini fridge.
If there is one thing Intel need to improve on with their newer chips it has to be temps, they want to add more cores to compete but at the same time they have to downclock them a lot and they still run piping hot.

2.3% downclock on a new hexacore from a fastest quadcore on the market is a lot?

Yeah if anything I'm impressed with the clocks on the 8700k. But we'll see all revealed soon enough.
Diablohead
Member
yet it's touching 10c hotter then the 7 series version, right?

AIO cooler recommended at a minimum
I would wait for release day reviews before judging temps (and performance as well of course).

It has 50% more cores and runs on essentially the same clocks on the same process. What is so surprising here?

7700k temperatures were not really something that should have happened. Now we are running 10 degrees higher then that. You don't see a problem here?

I want the chip not to run at the same temperature as my oven?
opticalmace
Member
What is the context of those temperatures anyway?
Don't know, I assume that is full load at stock speeds? Just those temps are bad, because that leaves pretty much no room to safely overclock whatsoever
and no one want their PC to catch on fire
But like what has been said in here, we won't know for sure until reviewers tell us what is up with those temps for sure. All I know is I would never get a CPU that gets that hot, not worth the risk to me.

Well I won't be regretting that Ryzen 1600 any time soon it seems.
opticalmace

What temperature do you think is dangerous for the CPU?
Well, if it gets much higher there's not going to be much if any overhead to overclock... and it seems like they are higher than the already high 7700k... so lol. I expect to see more people jumpy about delidding in the coming months.

What's wrong with 7700K temperatures?
I mean, they are on the higher side of things but this is a top end CPU, it is pretty much always like this with them, which is why I personally prefer mid-range HEDT "ticks" as they are usually rather cool. With 8700K there will be an option of 8700 which is only 100MHz slower in general but is rated at 65W TDP.
Also I know an old Gulftown CPU which is running at 100C at full load without much issues for more than seven years now. So it's really a question of which temperature a CPU can live with. Then there's AIOs which is pretty much a standard thing on top K models as people rarely buy these to run them at stock clocks.
I think going to higher bandwidth DDR4 memory should have positive impact for 4K gaming.
Also less stutters when going to latest i7, even at 4K.

Wait what, seriously? I mean, it's one review, but that's disheartening to hear. Guess the wait continues.
It's not a bad idea. You can buy a 1600 now and then pop a Ryzen 2 into your motherboard in 2019.

Don't some games still benefit? I quickly tried Crysis 3 and see the same framerate drops at the starting area in 1080p and in 4k (below 60fps), leading me to believe that my 4.5ghz 3570k is holding me back.
Yeah, your i5 is definitely holding you back there, according to DigitalFoundry even an i5 7600K can struggle with Crysis 3, it's a game that wants more than 4c/4t.

Why would a CPU impact performance in 4K? Even on 1080Ti you will likely be fully GPU limited there even on a 2500K.
So the new 15W mobile CPU is almost i7-2600K performance!

I meant the stream, not in game. I get a constant 142 in game (capped for G Sync).
I've actually tinkered and fixed my frame drop issue over the last couple days. Turns out it was the Twitch server I was using, despite having a good ping to it.
Pretty pleased it didn't end up being a hardware issue. Didn't have a single dropped frame while testing.
I don't really get it either. I mean I'm all for lower temp to have more room for overclocking, but if you do care about that the reaction shouldn't be to go for something slower.

Jesus that is impressive. I can't believe that level of power in a 15 Watt.
For reference, last year Kyle set up a 2600k pc up against a modern skylake build, and by upgrading the GPU, it didn't seem like the 2600k was bottlenecked in many instances (with a 970); https://www.youtube.com/watch?v=K9EJNa0y524
I mean. It's not that 2600k is any good by todays standards. But. 15 Watt CPUs fit inside the stupid thin ultrabooks with 10-12+ hour battery life. 2600k level of performance.. That is going to make multitasking in producitivity apps a completely different game.
And if this is the gains in the 15 watt, what are we looking at with mobile quadcores?
And if the 8-core desktop CPU are landing Q2 or Q3 2018, does that mean we will see laptop quadcores next year too?
I'm really curious about thermals on this thing, more than any other aspect of the reviews.
I built my PC last year just prior to the 7700k releasing and didn't regret it, since I have basically equal performance with my OC'd 6700k and the temps are better. Never goes above 70 at 4.5ghz on just a Cryorig H7.

This i7-8550U is already the 4C8T part: https://ark.intel.com/products/122589/Intel-Core-i7-8550U-Processor-8M-Cache-up-to-4_00-GHz
You can buy them anywhere now including Dell

I have seen reports of quite a bit higher temps on 7700k, especially OC'd. Now add 10 degrees to that and you will be running that 100 degrees on a 6 core with terrible thermal compound. I just don't trust that to last or not overhear my case. Mind you I do run the standalone corsair water cooler for CPU but still don't want to see those temps.What's wrong with 7700K temperatures?

Suggestion below for grabbing 1600 or 1600x this year and upgrading to Ryzen 2 on sale mboard toward end of 2018 or in 2019 kind of makes sense. Plus I mainly game at 3400 x 1440 so I am more GPU limited anyway (waiting for next year to upgrade my 980ti).
Another review leak/early review, this time of both 8600K and 8700K, these results are looking pretty good.

Less than a week to go to know for sure how it performs.

Meh, not worthy the hassle for someone already at 4970k@4.8
Try harder Intel.

Best of both worlds, as expected - fastest single thread performance helps in gaming while +2 cores pushes productivity benchmarks into R7 1800X level. 8700K will be pretty much unbeatable in gaming for quite some time.
Why does it make sense? You could run these CPUs at stock and would still have significantly higher clocks than with Ryzen, without egregiously high temperatures if you don't OC.
It's NEVER a good time to upgrade, honestly. :lol
My 2500K is getting really old, the PSU as well, I fear it'll fry my PC at some point because I'm really stretching its lifetime. (It's now 8 years old.)
So you're upset that the hardware you bought a few years ago is still very competent?
8600k hitting 5.1ghz overclock, not bad. Hot, but good speed. Wish this reviewer would have over clocked the 8700k and Ryzen CPUs as well.

Yes, we should be much, much farther in terms of performance in the CPU area.
Every area in the IT industry is soaring (SSDs, networking, GPU etc) but in the CPU we have at best a meansly 10% increase.
I want to upgrade my aging DDR2 server to my current pc, but i don´t want to do a meaningless upgrade for me either.
I think that review ran all other CPUs at default speed though except the 8600k at 5.1ghz. That's my only issue with the numbers. The 8700k should be able to go to at least 4.5 GHz vs 3.7, and all the Ryzen chips should hit 3.8-3.9 GHz. Its nice that a super over clocked 8600k can hang with the 8700k but it's not really a fair comparison when the 8700k can be over clocked as well.
You are saying that from the viewpoint of a professioal engineer, I presume.

You forgot to quantify the other areas in terms of percentages, I am fascinated.

Ofc not, im saying as a gamer. What else reason i would upgrade from my already "capable" cpu ?
:shocked:
