Fx8350 to i3-8100

LabR@t · 23 Oct 2017 at 16:30

Is it worth it?

Akagi · 23 Oct 2017 at 16:31

Probably not.

What is the machine used for?

P4Clock · 23 Oct 2017 at 16:31

8100 is the same as the old i5's and the i5s was about 20 faster thank your xf chip

At stock speeds it's about 40 To 50% faster

I lot of ppl have missed that the i3 is super cheap and now a full quad core

All use my pc for now is web and some occasional gaming.

I personally wouldn't bother then - I have a few mates with slower FX6300 based rigs,and they are still more than fine for those purposes.

The longer you wait the better the upgrade you have - AMD is even refreshing Ryzen next year with Ryzen+ and Raven Ridge APUs too. The latter should integrate a 4C/8T Ryzen chip with a Vega based IGP. We should get more hints of performance once we see the laptop versions launch in November.

Will hang on then, not struggling just had this pc for ages, and in miss upgrading/ building.

Buy a nice case with tempered glass and "re-home" your PC. Perhaps pick up some sleeved cables too for that extra bling or a new air cooler or AIO if you don't already have a good one.

All these parts can be kept for your new PC when the time comes and you can keep scratching that upgrade itch.

Yes don't bother if you system dose what's need keep it

Assuming your AMD is overclocked then this would be a downgrade. #controversial

Disclaimer: Assuming multi-threaded workloads

Downgrade for sure,future and present is threads, not MHz or ipc(but certainly helps). So going from 8 to 4 makes no sense,i5 (or other 4 threads cpus) only better in max fps in low intensity scenes, as soon as a lot starts happening on the screen ( explosions,smoke,many moving objects etc ) it will tank and stutter.
p.s: OCing CPU/NB is the must for FX chips.

pandem0nium · 31 Oct 2017 at 13:23

the 8400 is the one to get in terms of price/performance. Though the I3 should still give you a nice increase in performance.

dbmzk1 · 31 Oct 2017 at 18:02

Why are people saying it's not an upgrade or even a downgrade?

The i3 8100 will be significantly faster at almost everything...

AiiR · 31 Oct 2017 at 18:42

i3 8100 will spank the 8350, but if you don't game much then there's little point in upgrading to a new platform.

P4Clock · 31 Oct 2017 at 20:34

the i3 is last gen i5, it will kill the 8350... but if the 8350 still dose what you need it to then wait and upgrade latter.

Terrorfirmer · 31 Oct 2017 at 21:00

The i3 kills it stone dead in gaming for one, for me it would overall be a major upgrade on the FX and pretty much worthwhile.

Downgrade for sure,future and present is threads, not MHz or ipc(but certainly helps).

This is not true. The IPC of the FX is too poor for threads to save it in CPU heavy games. Case in point - Fallout 4, Battlefield 1 multiplayer, etc. Games that are multi-threaded but run like ass on FX compared to Intel i5.

CAT-THE-FIFTH · 31 Oct 2017 at 23:15

I wouldn't buy a Core i3 8100,as its pretty much the worse time to get a lowish clockspeed 4C/4T CPU now IMHO if you intend to keep it for a while - I would either get a Core i5 8400 or Ryzen 5 1600,or stick with the FX8350 for a bit longer if you don't have the budget for one of them now.

Edit!!

Regarding,FO4,as I have played it for around a 1000 hours now,one playthrough with a massive amount of mods(a few 100),I would get a Core i5 8400 over a Core i3 8100. The engine pushes one to two cores quite a bit but also shows lower level of scaling on additioanl threads for upto 6 in total. Its why a Core i7 4C/8T was generally quicker than a 4C/4T Core i5 CPU and why a 6C/6T Core i5 and 6C/12T Core i7 are the same in the game.

So regarding the topic: "is it worth it?" - answer is: sure not. Was i5 (modern i3) better cpu than FX in 2012 ? Sure it was. Is it better in 2017 ? Sure it is not (insert #finewine memes here). However in some cases dependent on the app and how good it could parallel the tasks, 4 threads + higher MHz + ipc advantage will be > that 8 threads, but adding more background tasks could tip the balance other way. Making the long story short: would be typical case of wasted money.Coffeelake i5 or ryzen5 thats minimum you need aim to.Can't believe we are back to square one again, had similar debates when the first 4 cores where hitting the market and higher clocked 2 cores where showing better results.

p.s: As CAT pointed out using Fallout4 as the "multithreaded" example is just shows your incompetence.

He said browsing web and some gaming, in those scenarios the new i3 is going to be significantly faster than the FX. Even your basic Pentium G4560 is going to absolutely demolish that FX in gaming and typical web usage.
Now the question is if it's worth spending so much money on an upgrade if those are OP's only workloads. In my opinion probably not, at least not while DDR4 prices are high and the cheap Coffee Lake motherboards aren't out.

I wouldn't have iether for gaming but the FX-8350 will be a better gaming CPU even with lower frame rates, the G4560 with newer titles is always going to have its resources maxed out, its known to be a stuttery CPU for gaming because of it.
Going from an FX-8350 to a G4560 would land him more FPS but a worse experience.

It looks like the OP is not willing to spend more than £100 on a CPU, the older i3's are still way over £100 so the one i would recomend is the Ryzen 3 1200 at £95, its a good solid 4 core.

the 8100 as a good solid 4 cores so how would the ryzen 1200 be better because it has 4 cores?
