AMD FX 4320 vs 6300 - thoughts? [Self-Crosspost from SPUF]

[Wheezald Locka]

We've been having quite a lot of fun with the reviled good ol' FX4100 for a pretty long while now, and it seems it's time to part ways.

I'd love to hear from fellow SPUD dwellers on the aforementioned dychotomy - yes, it is exactly that.

I have been researching fairly heavily and ended up with this kind of a choice.

I won't be switching to a different socket for now. It needs to be AM3+, my wallet says so.

As for the contenders, both made of Piledriver(TM) architecture, both sport a 95W TDP (which is a relevant factor to me); after that, differences occur.

4320 has two modules/four logical cores, with a lovely round 4GHz per core.
6300 remains at the somewhat more modest 3,5GHz clock, with 3 modules/6 cores.

4320 has a 4MB Level 3 memory cache, while 6300 has 8. This one difference leaves 4320 at a disadvantage where memory/core is concerned.

4320 has faster cores.
4320 is cheaper.
6300 is an ugly number.
6300 has moar cores.
6300 has moar memory.
6300 isn't THAT much more expensive.

See the dilemma here?

Please discuss.

I'll appreciate all insights* :D


* And ignore all Intel shills ;)

Due note AMD CPUs are the best at overclocking potential there's a record of 8.5 ghz on a AMD CPU but why have that much? it's only numbers really idk what that 8.5 ghz will do but I suggest right now a good Intel CPU or get zen

Between the two I'd certainly go with the fx 6300. The single core performance doesn't really improve with FX cpus very much especially at such small frequency differences due to the flawed 2 core 1 fpu module design of Piledriver. The 3 FPUs in the fx 6300 vs 2 for the fx4320 is actually the biggest advantage it has and are absolutely worth more then whatever miniscule difference exists in single core.

Between the two the FX6300 is the better choice but try for the alternative FX8300 if you can.

8300 is a bit of a stretch, although maybe not totally impossible. Y'know, I make my upgrades very seldomly for a reason. ;p

Zen will be AM4, so just as with Intel, this would require a brand new mobo. Not within the scope.
Maybe one day I'll splurge and build a Zen machine, but that day won't be this year, nor the next. :>

amd does hold the high ghz trohpy, but their ipc is crap, they are nowhere near intels performance

start over with a new build
its not worth buying a 5 year old cpu when an i3 or pentium g will be better than the one you have

You need to assume that I have a compelling reason for not making a new build.

you can keep most of the components

to upgrde cpu/mobo requires a teardown of the current build, as much or more work to upgrade than a new build from scratch

No kidding, fellow sentient.

I've done this before. I made the current build myself. Then I went for total cleanup lately, involving unscrewing most of what my tower consists of. I know what I'm talking about.

That's irrelevant. I won't be making a new build for a while, that's it.

[MrMcSwifty]

I don't understand what the point is. Did your 4100 die or something?

Neither of these two options is going to be any significant upgrade, performance-wise.

Just seems like a waste of money, tbh.

[Bad 💀 Motha]

If the CPU still works, I would just keep using that machine as-is and save up for newer Intel Skylake or AMD Zen based Motherboard+CPU+DDR4 RAM

[Space Coward]

As a few others have said, Intel has superior instructions per core to the AM3+ platform-- but that doesn't make AMD any bad.

My recommendation? Go further than even that. You can get an FX 8320e at $130, or FX 8320 at $150. The FX 8320 sits between the i5 3570k and the i7 3770k in performance on Passmark, with four hyperthreaded cores (eight logical cores). You can overclock the living crap out of it, but at stock the 8320 will give you 3.5 GHz or 4GHz Turbo.

If you don't want to buy a new motherboard, and don't mind skipping out on the rather impressive performance of a Skylake i5 6400/6500 (with the significantly less impressive price), go for it. Just make sure your CPU fan and power supply are ready for 125 watts of molten textures. I just got one myself, and so far I'm very pleased with performance. This isn't even overclocked, and with a mere R7 360; I'll be trying it with my 280 soon.

As for bottlenecks...

It'll be "there," but it won't be severe in the slightest. After months of testing an R9 280 and decade old Pentium, I'd say I have a right to say that.

[_I_]

at the 8320e price, you can get an i3 6100, but it will need a new board and ram, but offer better performance and easy upgrade to i5/i7 6xxx

8320 does not come close to an i5k in games
overall it can be close, games need better core performance vs more cores

if your fx4 works, keep it and save up for a new cpu/mobo/ram combo
