i7-8086K vs i7-9700K vs i9-9900K

[-rascal-]

I had recently found out the PSU on my X99 system gave out, and probably took out the poor ASUS X99 Deluxe II motherboard with it .... fingers crossed, hoping my 32GB of DDR4 RAM is still alive.

For that reason, I am prepared to get a new CPU + Motherboard if things turns for the worst.

I am deciding on which CPU to get: i7-8086K, i7-9700K, or i9-9900K, paired with a motherboard that is comparable to the X99 Deluxe II in features, and overclocking capability (e.g. no crappy VRM system).

 

I thought about going with the X299 platform, but it might be too steep in price.

Plus, 12+ cores seems a bit excessive for what I really need (difference between WANT and NEED).

Considered Ryzen as well but...these considerations:

• My EK custom loop currently does not support socket AM4 / TR4 / LGA 2066 (might need to get a hold of EKwb to send me an adapter kit)
• 32 GB (8GB X 4) of DDR4-3000 CAS 14 G.Skill RAM; not sure how nice Ryzen will get along with those

JUST got a quick phone call update: Confirmed X99 motherboard is toast, but RAM is still good.

 

 

What Z370 / Z390 motherboard would you recommend to pair with the i7-8086K / i7-9700K / i9-9900K ?

I'd go for the i7 9700K and Gigabyte Aorus Master, should be a great combo. 9900K is really expensive and doesn't make much of a difference in gaming. Heck, even an i5 9600K  would be fine, my older 8600K at 5GHz kept up with a 1080 Ti or SLI 1080s at 1080p, 1440, and 4K easily. 

 

Also what X99 CPU did you have? And did you know EVGA has the Classified X99 B-Stock boards for $99 right now? You could just grab one of those if the CPU is still good.

i7-9700K over the i7-8086K, eh?

$10 difference between the two; $519 for the 8086K vs $529 for the 9700K.

Thanks, I'll have a look into that board -- from what I know, a lot of Z390 board were lacking in the VRM department (I'm looking at your ASUS).

 

The CPU is an i7-6800K -- Broadwell-E architecture, so it will be a nice bump in performance.

I still need to confirm whether or not the CPU is good...that's the thing.

The local Memory Express store opened up not too long ago, and they don't have an extra X99 set-up they can use to test...

I'll definitely have a look at the B-stock boards too!

 

I was thinking of just selling the CPU locally, or here on LTT Classifieds, to get some money back.

If you can't confirm the CPU works and would let it go cheap, I just bought one of the Classified boards so I'd defo be interested if you don't wanna keep it. 

 

And yeah, the 9700K beats the 8700K by a bit IIRC, even without hyper threading. And the 8086K is just a better binned 8700K so once they're both overclocked the 9700K would likely win out by a teeny bit. Like I said, even the 6 core i5s are fine, most newer games don't seem to scale well past 6 cores, only really need more for a bit better 1% lows or streaming and other multithreaded workloads, or just because you can afford them and moar threads moar better.

They actually the 8700k out paces the 9700k by a significant margin in certain applications. I mean a stock 8700k beat a stock 9700k in the application and the 9700k has much faster clock speed. I would personally pick the 8700k.

I assume OP is gaming, and that's where the 9700K is faster AFAIK. 8700K might win out in things that scale well with its 12 threads vs the 8 on the 9700K though. 

[Sorenson]

The 9700k and 8086 preform almost identically. If you're looking to save money i've seen the 8700k at micro center for 330$ and you could just bump the clocks up on it to make it an 8086. I would go with either the 8086 to save a buck or the 9900k.

Ryzen hardly has any memory issues anymore. That was a 2017 problem.

The margins are not significant in gaming though when they are at the same clocks. I would personally go for the 8086k just because it is a highly binned limited edition part and cheaper than the 9700k.

Good point. You can delid it much easier too, so it'd probs do better on temps.

I'm up in Canada, so no access to Micro Center unfortunately...

I'll have to see if there are any (bundle) deals for the 8086K / 8700K / 9700K...maybe the 9900K.

Thanks!

I had thought so. Thanks!

Gaming, and data crunching (in MATLAB), coding (in Python / VHDL / Verilog) for work mostly these days.

I haven't done much rendering, video editing / encoding in the last few years haha...no time for that stuff.

(I was working 7 days a week for a full year and a bit...never again)

Keep in mind that languages like Python run on a single thread (unless you use libraries like thread pooling). 

[-rascal-]

The Python code I am working on is multi-threaded (e.g. control mechanical shutters, filter wheel, X-ray tube, high voltage, etc).

 

I ended up getting the i7-8086K and a Gigabyte Z390 Aorus Master.

Arosu Master and Maximus XI Hero were exactly the same price..BUT was able to get an extra $50 off the Gigabyte.

 

The doubled (4 x2)+2 phases on ASUS' high-end boards scared me away.

This is coming from someone who prefers ASUS motherboards -- and have exclusively used ROG / higher-end boards only.

 

First impression with Gigabyte's UEFI BIOS:

• It has improved a lot since the Z77 / Z87 days
• Still not as user-friendly versus ASUS's BIOS, but happy overall
  • e.g. CPU / Cache / DRAM multipliers and settings are on a separate menu from voltages....you need to go back and fourth between them
  • Compared to ASUS, multipliers/ratios are near the top of the menu, and the voltages are just further down the list

 

Still getting the X99 motherboard + CPU checked; will hopefully know sometime Friday / Saturday.

Will let you know the status of the i7-6800K CPU @Nocte

UPDATE:

Local shop did some testing further testing for me. Confirmed CPU, oddly enough, is dead. 

I'll have to do the RMA with EVGA (for the PSU), and with Intel...
