14700kf Build

[Amraam]

Contemplating upgrading my 8700k rig, whilst retaining my rtx3080. My 8700 has a nice stable 4.8ghz over clock so wondering how much benefit the following build would yield me?

New case because my current case nzxt s340 (love it) doesn't support AIOs larger than 280. PSU because the seasonic hasa bug where it incorrectly goes into a current over draw protection shutting the pc down. I have currently gotten around this by using msi after burner to slightly under volt my GPU, but I'd rather bit risk it on a new system. I should still be able to rma this current psu...

Thanks!

8700 w/ 6 cores and 12 threads and a decent overclock will still hang in there pretty well, and especially at higher resolutions not be much of a bottleneck to a 3080 - I can't really quantify exactly how it would stack up though.

What I would say is I've recently done a 14700K build and have absolutely no regrets.

The 14600k looks like a solid option if gaming and no slouch in rendering but the 14700 is going to better mulitthreaded workloads

Intel Core i5-14600K Review - Impressive OC Potential

Intel Core i5-14600K is the most affordable new processor released today. While it may look weaker on paper it still packs an impressive punch, especially for gaming. In our review we reached an impressive 5.7 GHz on all cores, which unlocks quite a bit of additional performance.

Eagerly watching this thread. I'm in the same boat. Plusses for me are Pci e 4/5, ddr5, better audio (mother board dependent) and better io. In real world terms I have no idea how much better this is compared to my z390 8700k with mid range 32gb ddr4.

I was leaning towards the amd 7800x3d but intrigued by your choice. Why the 14700?

The main reason to pick the 14700 over the 7800x3d is the multi threaded workloads where it excells making it a good all rounder.

Oh and if you don't mind making your energy supplier richer

Gaming then the x3d is anything from 3 to 15 % and the AM5 platform should allow future upgrades while intel will change platform next time out.

PCI-e 5.0 support on the 14th gen is a bit woeful really, aside from supporting PCI-e 5.0 GPUs - if you want to use other PCI-e 5.0 peripherals you steal bandwidth from the GPU

Personally I went 14700K amongst other reasons in gaming workloads at decent resolution/settings it mostly is very close to anything out there, even much more expensive CPUs without the trade-offs you see with other CPUs - the 7800x3D is a very strong gaming CPU but the compromise can be up to 40% slower in productivity type workloads for a small percent faster in games at anything over 1080p.

Thanks all. I haven't ran an AMD since a 4400 about 18 years ago ha. I never really keep in the loop with gaming hardware until I get the itch to build something.

14700kf seems to sit will in specs and seems to be a nice step up from my 8700k. I don't think I need to replace my 3080 just yet, especially as it's only 18 months old. Could be tempted by a 4080 super at some point or wait for 5000s.

Any advice on RAM? As I say I'm bugle out of the loops with gaming hardware. Whag speed ddr5 should I be looking at? And 32GB? Any need for 64GB?

I don't think, in honesty, that I need a new rig, but the itch can be strong, can't it?

What I would say is I've recently done a 14700K build and have absolutely no regrets.

I went to a bottleneck calculation site (I know, not exactly a pure science) and it quited an 18% bottleneck, however it gave no option to replace the stock clock of 3.7ghz with my stable 4.8ghz.

I'm truly wondering how much gain I'd actually net. My brother in law is telling me I should definitely be looking to get off 8th gen now, but he's minted haha.

It's always that stupid annoying "15th gen and 5000 cards are around the corner..." but at what expense. Plus at least with current gen all firmware niggles should have been ironed out etc.

Oh and 'futureproofing' has become my least favourite word in this world. Nothing is certain and tend to rarely upgrade individual components instead of doing a nigh on full build every 6 years or so. However, someone made a good point above. AM5 will be around longer than Intel's 1700 socket which has been used for three (two and a half?) gens now...

Maybe I should hold off another year and go all in on a 15700k and RTX5080? Plenty of time to save up the nearly £4k that would almost certainly cost

@Amraam where is your pc struggling ?

It's crap at scratching my itch?

I guess I just want more performance in Cyberpunk. Would love to be able to enable path tracing, but I know that I need a 4080 ideally for that, so I can employ native frame generation. The FSR 3 mod has given a huge FPS boost but at the cost of quite a few visual bugs I've yet to find fixes for.

I should really look to rebuild the OS as a start, as I haven't done yet once since it was built in January 2018. Same goes for thermal paste, but temps are good.

So get yourself a 4080/super if you can afford it then upgrade the rest at a later date if needed.

Alternatively hold fire for the 5000 series

Thate pretty much along the lines of what I was originally thinking but I would (not hugely educated) say my 8700k is already at its limits for a 3080. Would it not be quite the bottleneck on a 4080?

I doubt it would be huge loss in performance but no don't you'll loose some FPS, you also need features that only the 4080 can provide.

Spend your money on GPU first makes sense to me then change the rest if you want to push the GPU harder, you may find it's enough without.

I also hate the word bottleneck.

Yeah, I do too. It gets thrown around a lot, especially when people don't fully understand what's going on between a CPU and GPU etc. I hold my hand up to that to some extend, absolutely.

I'll hold off for now. I have an outstanding RMA for my seasonic PSU where it would protection shutdown under GPU load and a workaround is to undervolt the GPU slightly. I submitted it 20 months ago and never got around to sorting it because I'm an idiot. I've just been cheeky and asked Seasonic if there's any chance they'd honour it, so I need a new PSU anyway. Might try a Corsair Rm850x model

Love the rmx

But Mite be wise to atx 3.0 and nearer a 1000w just in case you wait for a 5000 series GPU which I suspect will use more power.

Enjoy.

Good shout. I'll take a look, thanks!

 

[Amraam]

I see 4080 Supers have officially been announced by nvidia. Hmmmm....

 

[Amraam]

Sorry for the bump, just had a slight change of plan.

So my PSU is (hopefully) going back to Seasonic under RMA, but I don't want to be without my PC for this time, and so thinking I'll grab a Corsair RMx 1000 Shift so that I've got head room should I need it. But, it won't fit in my NZXT 340 case, which got me thinking. My case will not let me have my 280 rad the 'correct' way up (literally 2mm or sis the difference needed to flip it and get the holes to align). The pipes are at the top, but they are above the CPU block by about 3" so I'm not too concerned; it's just less than ideal.

So do I pick up a new case, this PSU, and a fresh set of 2x16GB RAM (currently 2x8GB) to give my current set up a little boost before picking up a 4080 Super FE? See how that goes, and then can always upgrade to a 15700K etc. next year?

Plenty of room in the 216 case for roof mount 280mm aio.

I kind of have my eye on the H9 flow, but it's a bit on the thick side. The one time I think about futureproofing is cases haha. I want to get one that supports 360 or even maybe 420 options (just in case... boom boom), and cos I'm out of the loop (these crap puns are just flooooowing out of me) dual chamber is relative new to me.

Lian Li seem to be a fan fave for cases though so will definitely go check these out!

EDIT: oooh, whilst I'm in a foolish buying mode, can you get 90 degree power adapters for the 3080/4080 series? I hate the way this looks:
