Ive been reading about skylake x couple of weeks now but i just cant make up my mind.

the information i get is very confusing. There reviews , that at least for stock clocks , are a triuph for skylake , others that dont really see much of a difference and some that claim skylake is a disaster wait ti happen.

theres also various claims , that have not been reproduced in a larger scale about vrm issues , extreme heat , throttling whatever.

So my question is for someone who wants gaming and multitasking and price is no issue , on stock clock is it worth buy if you really want the performance or no , plain and simple because not everyone holds an electrical engineer diploma

edit im interested in 7820 since 7800 x seems a little obsolete with only turbo 1 in 4.0ghz and less multitask than r7

Skylake-X has no good value unless you're doing both workloads that rely on fast cores and workloads that rely on many cores, while not wanting to make a single threaded performance compromise.

Kaby Lake is superior for gaming and will still do decent in multi-threaded workloads. ThreadRipper is (most likely) going to be slower in single threaded workloads (look at Ryzen), but astronomically better than Kaby Lake (and also Skylake-X) in workloads that are easily spread over all its cores/threads. Bear in mind the SMT implementation of AMD is also slightly better than Intel's Hyperthreading (or so I've heard, I don't have numbers at hand to back that up).

TL:DR; buy Kaby Lake for gaming, buy Threadripper for heavy workloads, buy Skylake-X if you really don't want to make a single threaded performance trade off for the extra cores (or if you want epeen). Buying SLX also means: dellidding your chip and buying a custom loop to keep it cooled, while also providing extra cooling to the VRMs.

thanks , my problem lies that i think that 4 core will be obsolete soon and more and more games start to support multicores.

Ive seen benches that , like i said give new skylake x 7820 a solid 40 to 50 % better multitask and a 20 to 40 % gaming , single core performance.

Thing is i cant figure out if the phantom throttling ( what does even mean ... ) or the vrm heat problems exist in the stock performance or only when overclocked

We've been saying that for nearly 10 years. Single thread is still king and it will in all likelihood still be king in 5 years. Many workloads can't be properly spread over threads and the more-than-4-cores adaptation is too low for developers to invest in extra multi-threaded optimization. If it's for gaming, buy the 7700K (or wait for Kaby Lake's succesor).

The VRM problems are present at overclocked CPUs. The entire platform is flawed unless you mod out it's flaws (delid, cool VRMs).

If you want to burn multiple 100's of $ just in case, be my guest. But you'll have an inferior setup today (vs kaby lake), and your setup will be inferior in 3 or even 5 years. By the time your CPU bottlenecks, it's better to upgrade. An example: compare an Ivy Bridge quadcore to a Sandy Bridge-E hexacore, the same comparison can be made for every successor.

SLX isn't a good choice for you (or your friend).

I'm just going leave my temps after a 4 hour gta v gaming session last night here,



This is at 4.5 on all cores. The max temp on cpu is 54c. The reality is all cores and cpu were running mid-30's - low 40's. VRM temps maxed out at 44c. This is cooled with an H115i set to quiet mode.

Any issues people have with Skylake x and temps are exaggerated. If you want pretty fast clocks and low temps then oc for that.

Purely gaming you'd be better served by Coffeelake in August at the earliest. Newer process node, and older core design. But there's likely no upgrade path for Coffeelake. The newer core design might be harder to OC with due to the increased heat load vs the former.

Upgrade path is overrated anyway. I don't remember myself wanting or needing to replace my CPU only.
Whenever I think about a new CPU, I will most likely want a new motherboard, with new chipset and features.
I build my PC and keep it from 3 to 5 years, and then both motherboard and CPU will become obsolete.
Now people think that they will upgrade their CPUs. But then they will see ddr5, new pci express, new features, new sockets.
Honestly, most people won't upgrade their cpus only, even if they could.

Yeah intel doesn't tend to give you more than 1-2yrs of compatibility. I grabbed this 4ghz ryzen 1700 with a plan to upgrade to whatever cpu they bring out for AM4 in 2020 before they release their next socket with all those shiny new things =P

That's an excellent purchase indeed, but Zen+ compatibility is yet to be seen. AMD also loves to release their "plus" sockets from time to time.
They may as well say "sorry, new chipset needed". Who knows...

If money isn't an issue I'd personally buy a 7900x CPU very strong performance all around. Quad channel memory support lots of PCIE lanes and you have the option to go with 18 cores if you really need it. I would wait until the Rampage VI Apex and Extreme boards release since they probably will have adequate VRM cooling solutions while many X299 boards VRM thermal solutions have been questionable.

I do the same my pc cant play ultra naything i have a 4790 non k and an r9 290 , is like 3,5 years old . I want a new pc i can have it for 3 to 5 years , seems to me skylake x with a gtx 1080 or 1080ti will do that. For the multitask thing ryzen is fine but single core and gaming um not rly.

Btw about coffeelake i dont think we will see deckstop coffeelakes before next year spring or something unless intel likes to go bankrupt . People just hyping about an august release imo

Gaming on Ryzen isn't bad I have 6700K on a custom loop running at 4.8 and a 1700X at 3.9 honestly I can't even tell a difference with FPS counters on but I am at 1440p Ryzen has more then adequate for gaming. I honestly think it matches or exceeds BW-E clock for clock.
