am3+ cpu difference dilemma

[Niruvius]

Hi i would like to know what exactly is the diference betwen fx 6300 and fx 6350 and ofc same goes for fx 8300, fx 8320, fx 8350 and fx 8370. Also what is the difference betwen 8370 and 8370E.

I did notice difference in clock speed, but is there any other difference than that and how different are their overclocks. My friend told me that all of those cpus are same architecture just factory overclocked 6300 and 8300 and if i go and oc with proper water cooler they will all overclock to same clock speeds (based on silicon lottery) and will perform the same (if 8320 and 8370 are oc to same clock speed they give identical perforance) therefor suggesting me to go with cheapest one *6300 or 8300

FX 6350 is an overclocked FX 6300 - same for 8320 and 8350 and 8370.

EDIT: That means a guaranteed overclock = no silicone lottery - you also don't need water cooling, simple air cooling is fine.

[Godlygamer23]

Clock speeds are the difference. You might be able to get a higher overclock by going with a 6350 vs a 6300 for example - it's binned higher. The difference between the 8370 and 8370E is clock speed and voltage. The 8370E runs at 3.3GHz versus 4GHz and at a lower voltage, thus having lower heat output and power consumption.

The only difference between the FX-6300 and 6350 is the default settings (the extra 0.5GHz core frequency). Same idea with all the FX-8 chips. In fact all the FX-6 chips are the same as the FX-8 except with 2 cores disabled.

 

In other words, your friend is right.

Were they? I thought the 6100 and 6300 were different chips. Same for 8150 and 8350

Within the same architecture, they are the same. You are correct about the 8150 and 8350 being different, along with the 6300 and 6100. The 83xx and 63xx CPUs use Vishera while 61xx and 81xx use Bulldozer. Same applies to the 4 core variants as well.

Oh right, the FX refresh, right? I guess I remembered correctly

FX-6300 and FX-6350 just does not have same clock speed.

FX-8320 & FX-8350 is same story.

FX-8370 uses less power than FX-8350 and is clocked higher and has a better chance to reach better OC. (it currently holds world record and beat FX-9370 & FX-9590)

FX-8320E & FX-8370E uses less power but is clocked lower... (for low end boards)

 

Best value for most is FX-6300, FX-8320 or FX-8350. (but its lottery!)

8370 and 8350 have the same base clock, but the 8370 has a higher turbo by 0.1GHz.

You need to be more specific. The base frequencies are the same, but the turbos are different. It's not inherently clocked higher - it depends on the situation.

Yes but still higher!

Those are different, I was only talking about within the 63xx and 83xx generations. I didn't think anyone still talked about 61xx and 81xx lol.

[Dabombinable]

Yes but still higher!

They don't maintain the boost clock all the time-so they still aren't clocked higher only boosting higher. For example, my i5 4440 is sold as being 3.3GHz, when in reality it rarely maintains that frequency for more than a few seconds and mostly stays at the stock speed of 3.1GHz.

It's being sold as having a base clock of 3.1GHz and a boost clock of 3.3GHz which is in line with your experience and the advertisement.

When I bought my computer (as in I had it built), the i5 was listed as being 3.3GHz. Only by actually monitoring the frequency was I able to see that it was only boosting to 3.3GHz for a short while (I'd never owned a CPU that could boost beforehand).

Well, it's not like that now.

Ok i do understand so basicly go with cheapest 63xx and 83xx and hope for the good oc or pick 8370 *that cost around 50% more where i live.

Going with a higher clocked chip increases your chances of getting a better chip for overclocking - it still doesn't guarantee anything.

I know that Intel list it as being 3.1Ghz, but the computer shop I bought it from sold the i5 as being 3.3Ghz-I was ignorant of its actual specs as the last desktop CPU I'd used had been a Pentium III.

no, just get an i5-4460 and a cheap H series or B85 motherboard that will bitch slap the old FX in just about anything and you'll save by not having to buy an 8 phase motherboard and an aftermarket CPU cooling solution...you also get modern features such as PCIe 3.0 namely and you'll save on heat and power bills too.

 

The FX-83XX makes no sense what so ever these days unless you're building a cheap rendering farm.

 

Look, cheap intel kit vs cheapest possible kit that would work for overclocking the AMD FX, it cost the same:

The intel is even cheaper mind you!

FX 41xx, 61xx and 81xx series is the ORIGINAL bulldozer chips

FX 43xx, 63xx, 83xx and 9xxx is PILEDRIVER chips, they have higher IPC, bette scheduling and in general, clock for clock, better performance then bulldozer.

FX 8320e and 8370e is super binned chips. They are designated as upgrade paths for people with a FX 4xxx and 6xxx CPU on a lower end AM3+ board can upgrade without issues

FX8320e and 8370e is more likely to OC high then other chips as they are highly binned in order to maintain a little lower clock speeds then the normal chips, but at severely reduced voltages. This causes them to use 30w less... which is HUGE.

Just because they can maintain lower clocks at much lower voltages doesn't mean they'll overclock super well. I don't even think the chances increase at all of getting a good chip.

I cannot guarantee that they will all reach 5GHz, but you do not find a chip, designed to run at 125w, that can run at 95w with only 300MHz reduction to NOT be a highly binned example.

For reference, Anandtech has gotten their 8320e to 4.8Ghz, while ONE chip isnt a indicator on how well ALL are going to OC, it is still a indicator of what the "E" chip CAN reach.
