Overclocked FX 6300 or 8350?

HashtagMilk · Sep 7, 2014

What CPU would be better? I'm mainly going to be gaming on it. I would only overclock the 6300 to 4.5 ghz, and I do not plan on overclocking the 8350. The graphics card I'm using is a R9 270x

I would get the 8350. Why not overclock that?

LookItsRain · Sep 7, 2014

Why would you buy an 8350 and not overclock, but then overclock a 6300?

HashtagMilk · Sep 7, 2014

With my budget I can afford a 6300 and an aftermarket cooler + a better motherboard, but if I get the 8350 I'd have to settle with the stock cooler and a cheaper motherboard to fit my budget.

Then buy an 8320 and get a cooler, there the same processor, just the 8350 is higher binned.

TheMagicalWallaby · Sep 7, 2014

I agree with LookItsRain. Get an 8320, then get a good CPU cooler.

Never use the stock cooler.

To be honest, the FX-8320 and FX-8350 will both wind up at about the same clocks when overclocked with an equal budget thrown at the problem. You can spend less on the FX-8320, but you'll have to spend more on cooling to overclock to where the FX-8350 can get on less cooling, so it's sort of a wash there.

Example:
FX-8320 + Silver Arrow =~ $210
FX-8350 + CNPS10X Performa = ~$210
Either is going to hit ~4.4-4.6ghz. The 8350 will do it a touch more efficiently in theory, so I would tend to advise the 8350 over the 8320 except in those cases where the 8320 goes on special pricing for <$130.

The UD3P is cheap and has the power to do sub 5ghz overclocking pretty well.

All that said, an overclocked FX-6300 is actually going to break even (trade blows) with a stock clocked FX-8350 in most cases. Especially in real-time workloads where performance scales better with per-core performance than with more cores.

He would only need a Hyper 212 Evo or something similar to get to 4GHz on the 8350.

An 8320 with a $30 Hyper 212 Evo (or x model when that comes out), can get you to the speeds of an 8350 or even faster if your case has good airflow.

mdocod · Sep 7, 2014

Sort of proves my point doesn't it?

The FX-8320+ 212 Evo (this would not be my pick in this price class but I digress) costs about the same as the FX-8350 does with the stock cooler. Either could do ~4.0-4.4ghz (varies by chip) for about the same money.

You have the right idea. Get the 6300 and overclock it with a better motherboard. The 6300 generates less heat than a 8350 or 8320. Get a board with 8+2 phase power and vrm's that are heatsinked. I have a 6300 rig and an 8320 rig and I tend to use the 6300 rig mostly. I disagree with the Hyper 212 being a good cooler for an 8320/8350 also. Not enough mass or heatpipes compared to a more mid range cooler to dissipate the heat from an 8320 or 8350. They actually pull 275 watts from the wall say at 4.4 GHz. Much like a 9370 or 9590.

He would basically have an 8350 and an fair aftermarket cooler for the price of an 8350. The prices are not the same. An 8350 with a Hyper 212 Evo is $210 not $180. I was not sure if you meant that he needed that silver arrow cooler in order to get the 8320 to 4 - 4.4GHz. People have achieved that with the Hyper 212 Evo.

The Hyper 212 EVO is kind of weak. I can't recommend it for an 8 core cpu. Plus the mounting is so convoluted. I bought two Thermalright Ultra-120 eXtreme's off eBay and they show how lacking the Hyper 212 EVO is. Much heavier copper base. More and thicker heatpipes. I relegated my two Hyper 212 EVO's to an A10-5800K rig and a 1100T rig. My 6300 and 8320 can freaking heat the room at 4.5 GHz. Plus the THermalright's use the stock bracket and backplate.

Go re-read what I said. You've misinterpreted everything.

I made the case that the FX-8320 would need something like a Silver arrow to hit the same clocks as the FX-8350 would with something like a CNPS10X Performa.

I also made the case that the FX-8320 + 212 EVO costs about the same as the FX-8350 + OEM cooler.
