That's fine but there's no need to spend extra money for the 8370 name. Even if you plan to use turbo overclocking and need the higher TDP than E chips there are 125W 8 core FX chips for less.

Yes i know chris said the 8370 its faster, i dont use turbo i overclock it manually

At stock.

All Vishera 8 core chips are the same, with the exception of binning.*

9000 series chips are the worst, according to The Stilt. He even said, had AMD not invented the 220 watt TDP, they would have probably been trashed.

E series chips are the best, particularly the 8370E, in terms of binning — because of their low leakage

The Stilt characterized the improvements to the 32nm SOI process in terms of reduced leakage over time, as far as I've seen.

High leakage chips like the 9000 series require less voltage but produce more heat anyway. That's what I recall reading here. I also recall that, if going for the highest possible overclocks an E series chip will be more trouble than a higher leakage chip (like an 8320).

So, it appears that for anyone on air or AIO, an E series chip is the best choice. For anyone wanting an extreme overclock an 8320 or something is probably the way to go. There doesn't seem to be a good reason to pay extra for an 8370.

*I aso wonder if AMD is using more concave spreaders on chips like the 8320E on purpose. But my 8370E also had a concave spreader.

The 9590 only makes sense for someone who is wanting to use LN2 or who has a high-capacity custom loop. High leakage chips aren't what an everyday user with air cooling or a CLC wants. The 9370/9590 will get the highest possible overclocks, but you need enormous cooling capacity because of the leakage characteristics. For people just wanting 4.5-4.7 GHz, just about any 83x0 chip will get the job done these days, with the good ones making it to 5 GHz.

I would recommend an 8300 or 8310, or an 8320e. Those are all low leakage chips with a 95W TDP and have good overclocking capability to at least 4.5. Newegg's got the 8300 (3.3 base/4.2 turbo, 95W) for $119.99 right now.

not only looking for a high overclock but good performance and fast reaction ... and as chrisjames mention the 8370 has a good overclock and fast capability ,, if it makes sense ...i had no problem with my 9590 overclocked at 5.1 with liquid cooling but do to my errors or some reason wasnt stable enough ...

Binning is a huge difference so the chips are hardly "the same". I have about a dozen six and eight core Piledriver cpu's. Expecting to get a cheap 8300 to the same frequency as 8370 is pure fantasy. You may be able to do it but it won't be pretty.

My 8320e was on sale for $99.00 back when I got it. It runs at 4.6 on air within thermal spec.

It will run higher, but I get temp spikes around 70c on the core. I am no longer willing to do that.

Why do I see 8320s here that are being run at 5 or higher?

Getting an 8320E to the same clock as stock 8370 is easy even with a low-end board like UD3P. 4.3 static is not hard.

The low leakage chips typically need a ton of voltage to get where the regular, higher leakage chips go. 4.5 to 4.9 GHz. I have seen tons of evidence of that on this forum and I have seen that with my 8300, 8310 and 8320E. Where as my regular 8320, 8350 and 6300 and 6350 are much easier to get close to 5.0 GHz without hitting voltage walls.
