Changing the argument? He didn't say anything about timelines, he said that we have 6C thanks to RyZen, and that is not true, because 6C appeared in the roadmaps two or three years ago.



What market pressure? AMD RyZen has had nearly zero impact on general marketshare, despite all the hype, lies, biased reviews, and silly attempts to cheat the Passmark database. Today the database reflects reality of the low impact of RyZen in real world

Even lower if we focus exclusively on gamers

Why would Intel magically alter their normal release pattern if they weren't feeling market pressure? Or at least felt like they had something to lose by not releasing earlier than planned. I think you and your fellow Intel apologist are just being naive if you don't see this. I have a 7700k...I'm not an AMD fanboy by any stretch.
 
Is this the kind of thing Intel can change on a whim?

Perhaps Kaby sales sucked or they had a stroke of luck with their fab, who knows. X299's launch was a clusterfuck too, which also suggests pressure from AMD. It's a lot of coincidences all happening at the same time...

Their timetable change was probably caused by Ryzen but unless someone at Intel says something, it's impossible to know for sure.

But you call names to people whose only crime has been to mention here that: (i) 6C CFL appeared in roadmaps two or three years ago and (ii) "market pressure" means RyZen got about 4% market share in general and about 0.41% gaming market share.
 
Honestly, who cares why they are doing it? At the end of the way, a better processor is here sooner. Competition is good, with or without AMD influence, it's coming. Comparing the product vs Ryzen makes sense in this thread, arguing why they did it, doesn't matter - what's done is done.

1). There is no "crime." I have no problem with 6C/12T chips being on the roadmap. I never said I didn't see a 6C product on the roadmap. Nor have I ever argued such.
2). All the roadmaps and the usual Intel release cycle has been yearly (or longer with the exception of the 1150 Broadwell chips that were never readily available, but Haswell essentially was around for 2 years). Suddenly, Intel releases 6C products much earlier than originally on the roadmap.
3). Certain Intel apologists on this forum claim that AMD had nothing to do with this change, and that Intel's plan all along was for KBL/Z270 to be essentially an 8 month stop gap between SKL/Z170 and CFL/Z370/Z390.
4). I think that's bullshit. It seems far more likely that AMD's high core/thread count forced Intel to release CFL earlier than they initially expected to when they created the roadmap regardless of the relative market share.
5). My personal feelings on that aren't a personal attack on you.

I wonder, how Intel will deal with TIM and IHS. I know, that in old days Kyle and crew checked if cheese can be a thermal paste :), but the recent ideas of Intel go a step ahead. Some of 7700ks are getting mad temp spikes to 90c and Intel says "ye shall not oc".

But if they have such issues with 4 cores, won't 6 cores have even bigger issues? After all it will be much densely packed die with crap TIM, because I doubt that they will solder the lid. So it might have issues with becoming OC king.

Wonder where they are getting +11% ST on the 8700K.

juanrga said:
Yes. Higher clocks provide 4% and faster RAM would provide another 5%. That already accounts for 10%.

Core i7-8700K vs Core i7-7700K

http://www.cpu-monkey.com/en/compare_cpu-intel_core_i7_8700k-763-vs-intel_core_i7_7700k-664

9% faster ST and 52% faster MT @ CB 11.5

Compared to Ryzen 7 1700X about the same MT performance in synthetics but much better ST, and that's before OC...

that, or could be a real optimization intel didnt give to kabylake but instead give to coffee lake. how would uncore benefit in ST performance btw, donno how it works.
 
The ST % increase seems to come from the slightly higher single-thread clocks, cache, and probably RAM as others have mentioned. :)
It could also be one specific benchmark that favors cfl in some way.
 
Steam surveys and cpumonkey now official sources of data. I mean last week the i3 was an i7 for 100 bucks and that lasted a few days.

I can't say it isn't funny seeing some so bent out of shape.

I would say it is not that clear cut because Intel's normal release pattern became FUBAR with Broadwell where many analysts wanted them to just write it off and skip straight to Skylake even if meant say 5-6months after the launch date of Broadwell, however Intel tried to make a product cycle that squeezed some life out of Broadwell and also squeeze life out of going tick-tock-tock.
Doing this means one ends up with a messy product cycle/map and eventually you end up with a rubber-band situation as their segments are not just consumer but workstation/server/HPC as well.
I mean a lot is made publicly of AMD Epyc for HPC but those ignored IBM will have at least the same or likely more impact in this segment with Power9 that is very HPC competitive.

I am not convinced much necessarily changed with the advent of Ryzen apart from it did affect Intel from its HEDT product strategy, but then as an example they were already shifting some aspects of that closer to workstation than consumer anyway such as the mesh architecture (nothing to do with AMD doing this but fits better with Intel's HCC CPUs).
In other ways Ryzen did create a response change with HEDT line albeit some not as much as has been emphasised; the HEDT products may be early but it is probably only 3-4 months earlier than they would ideally want and tbh AMD launched their product too early.

cpu-monkey provided detailed performance results for Coffee Lake-S, you can browse them here. As any pre-launch a grain of salt is required, but the numbers are very promising. Made a Kaby Lake-S comparison below.

3.7 base clock? We should be able to o/c the hell out of these right?

Also-
Are these 6 core i5 models going to give some of the older i7s a run for their money?

I really hope the 8700k releases sooner rather than later, I'm all set to upgrade my aging 3570k.

I am with you. My 3570 has been a champ. I am looking forward to the 21st.

However, my gut is telling me that this release event is a semi paper launch. We will not see retail (excluding oem) coffee lakes or z370 boards until later this year. If my hunch is correct, I will very much be looking into a TR 1900x platform.
 
Pfff...3570K...

Try an i5 750 @ 2.67GHz stock clock...

Going to an i7 8700 (NON K-series) will be a MAJOR upgrade...

As will the new H370 ITX motherboard & 16GB DDR4 2666/14 RAM & 500GB M.2 NVMe SSD that will go along with the 8700..

And a new GPU...

I'm gonna do a Goldilocks & go with an EVGA GTX 1080 Hybrid...

Because that middle GPU is JUST RIGHT...! ;^p

Slap a 120mm AIO on the CPU...

Stuff it all into a Phanteks Shift with a Corsair SF600 SFX PSU (already have the PSU)...

Shiny...!

God it upsets me how expensive really high end ddr4 is. I could get 32GB (2x16, for itx) quality gear so cheap comparatively, About a year ago..

When is this crap gonna end?
 
Didn't do a survey, but just scanning a Newegg mailer for 2x16GB of DDR4 at 3200+ pushed north of US$300...

I paid half that for mine, about this time last year. It's wild, and going radically in the wrong direction.

im more interested in ST performance but from the cpumonkey screenshot u posted, man that 218 at just 4.5? or was it 4.7ghz, thats damn high for CB15 ST.

seriously if that ST performance turn out to be real, it'll blow away any chance of me getting ryzen unless ryzen 2 or 3 sees a bigger improvement than this, along with a higher capable frequency chip, say 4.6ghz.

THIS IS SO HYPE DAMMIT

218cb is for the single-core turbo: 4.7GHz

Zen 2 is a 2019 product.

When DRAM companies ramp up production beyond what the datacenter, mobile and smartphones uses. Samsung for example moved from 12% to 27% server memory alone in the same timeframe. Desktop is last again.
 
I thought they were the same thing. That's a bummer.
But to be fair as exciting as Coffee Lake is, it's simply a 3rd Skylake with node improvements.
 
Hell, if 'mature Zen' means that it breaches 4.5GHz under stable overclocks, AMD will find a lot more customers; especially if they also deal with the CCX latency issue that needs countering with faster, and currently quite expensive, DDR4 memory.

Some questions:

Therefore you expect [Summit Ridge --> Pinnacle Ridge] will provide higher overclocker gains than [Trinity --> Richland] did. Are there technical reasons why 14LPP would mature better than 32SOI?

How can AMD fix the CCX latency issue, if Pinnacle Ridge uses the same microarchitecture?

Why we have always to wait for the next AMD product? ALWAYS!

Why isn't this discussed in AMD threads? This is about Coffee Lake

Wow, that's a mouthful of questions for what is clearly idle speculation about AMD's future parts, in response to your post in the Coffee Lake thread...

You make no sense if you have you use for that many cores why are you even looking at 8700k
 
The question of eight slower cores versus six faster cores is certainly worth pondering.

Now, the question of consumer platform versus HEDT platform, that's certainly something else, AMD or Intel.

Wow I think your right on the money. Allways waiting for something around the corner.

My last AMD was socket 939 opteron. Then q9650, then 3570k. Back then I was perfectly happy with q9650 but I could sell my old setup for the price of the 3570k setup so I did and looks like It was the right choice. I have been itching to upgrade but looking at performance of what is out there doesn't make sense to upgrade. 8600k/8700k will change that if the 8400 vs 7700k leaks are confirmed. Got 16gb of ddr in hand that I got for 90 and a z270 board that I'll likely have to sell
