Why does anyone buy a FX-8350? - Page 2

post #11 of 21

AMD and Intel dont make a different CPU for each model. AMD for example doesnt make a 8350, 8320, 6300, 4300 and so on. They make the same chip for each of them. The ones that can handle the highest clocks on all 8 cores get the 8350 stamp. The ones that dont work as well get the 8320 stamp. The ones with 1-2 questionable cores get the 6300. 3-4 shakey cores and its a 4300. So in theory the 8350 is the best chips of the bunch and the ones youll have the most luck overclocking with.

I bought a 8150 for that very reason. Im not able to get it higher than 4.5 but I can do so on 1.39 volts, OCCT, IBT and P95 tested and stable and its solid enough that I can run Cool n Quiet which keeps my idle cores at a nice, cool 1.4 Ghz @ .85V. thumb.gif

The difference isnt huge though so dont think that a '50 will hit 5.0 while a '20 will only do 4.2. From what I can gather from various forums, youre looking at only a couple extra MHz. I like to think though that the higher binning is why mine will run fairly high stable enough for CnQ.

I think it boils down to the price. If its more than $20-30 at most, its probably not worth it really unless you just want the extra insurance. I wouldnt consider it a waste of money if you did buy a 8350. If I do buy one to hold me over til Steamroller gets here, itll likely be a 8350.

Yeah, obviously any chip that has a defective core can't be sold as an 8 core processor, but I do question how much of a difference there really is between the 20s and 50s, since the 8xxx series are all going to be top shelf anyway.

The manufacturing yields for these chips have gotten quite good, and I would say there's a good chunk of 4xxx and 6xxx series chips being sold with good cores disabled, and those lines are going to get the worst chips that have all 8 cores functioning.

Especially now, since Vishera's been out for 6 months already, I would bet the only chips being sold with truly unusable cores are the 4xxx series.

at that point its a crap shoot, however what we have mention above is the reasons why

+Rep. Great info; I actually had no idea of this and always wondered what the difference between them were.

They're both unlocked, so you're basically paying more to have a higher default multiplier, which you're probably going to change anyway.
Because when I bought it a while back it was only £10 more than an 8320, yet £40 less than an i5 3570k. Prices have changed considerably since.

Is this honestly how AMD produces ALL of their FX chips? This method seems way too unpredictable.

I would believe it if it was only for the Athlon line or something, but not every single FX chip.

The intel K/Non-K versions are totally different. The non-K has a locked multiplier, the K is unlocked (and happens to have better integrated graphics, which is a joke since nobody who buys the K processor is using integrated graphics, unless they're making a server, where the graphics don't matter anyway). In fact, the 3570 and 3570K have the exact same multiplier out of the box.

but if you're building a server, you might want VT-D, which doesn't come on K chips. le sigh.

Needed a CPU for my motherboard obviously.

No, because the price difference is usually $30 (it varies where you look, and sales change everything) and it's clocked 25% higher with the same TDP.

Basically, 8350's are binned 8320's and usually require less voltage to OC higher:

Same reason people go for 9590's. They're binned 8350's that do well when OC'd
