Revenger, OC'd the 8350 is probably close to the 2600k. Hard to tell because I only have 2500ks!Do you feel it is equal to a 2600k?
I'll be interested in your findings.I have just received mine, ill let you know in a few days
Been busy with family matters, early thanksgiving as oldest daughter in military and could only get leave this past weekend plus Baptism for our grand daughter!
I've spent time now with the FX8350 which has replaced the FX8150 in rig 3 below.
Well first the price is much better even with the inflated early release prices. My particular chip needs a little more voltage to run stable at 4.64Ghz (23 x 202). It IS faster at the same speed than the 8150 but not a HUGE difference. Example Cinebench 11.5 CPU at 4.6Ghz - 8150-7.57; 8350 - 7.97.
One area which really shows improvement is power usage at higher OCs. EX. I used my Kill-O-Meter to measure wattage of the system (less the monitor) at the wall for both the 8150 and the 8350 running at 4.6Ghz full tilt with IntelBurn test on a 20x run. The 8150 was as high as 433 watts while the 8350 was as high as 376 watts. About a 55 watt difference. The 8150 can clock high but the heat kills you. The 8350 clocks a little higher without the exhorbitant heat. For me the 4.64Ghz 8350 is about a 4.8Ghz 8150 without excessive heat or voltage. On mine I have the voltage kicked up to 1.468 v to assure ABSOLUTE stability without excessive heat. For example with my Corsair H100 cooler my CPU even running IBT over 20x never exceeds 56C and most times it's in the high 40s or just over 50. Core temps are lower. Moreover when running normally the temps appear lower than the 8150.
I feel that this chip is neck and neck with my 2500ks at their OC'd 4.53Ghz speed and beats them in muti threaded apps (Cinebench 11.5 2500k=7.17; 8350=7.97. Povray 3.7RC6 2500k=3minutes 26seconds;8350=2minutes 30seconds.
Cannot tell the difference in gaming otherthan synthetic benchmarks.
IF you own a AM3+ mb with decent OCing and want the best overall cpu, the 8320/8350 now hit the mark. I think all of the little tweaks to the 8150 now create a decent chip.
BTW: For all of you COD BOII fans (myself included) it runs just as well on the FX8350 as the 2500k rigs.
Much less. If I recall it was at least 100 watts less. At idle the difference is much less. I'll measure them later tonight and post.How much power does you overclocked 2500k rig use under the same conditions as BD and Vishera? I notice you did not mention that.
Before overclocking how would you compare 8150 vs 8350 performance? Or near stock?
IE on a cheap motherboard with limited overclock potential.
I decided to run the FX 8350 stock for at least 1 week. Frankly so far hard to tell difference between stock and OC at 4.6Ghz. Of course stock turbos to 4.2 Ghz so stock is really set high. What is nice is at stock it runs incredibly cool.http://www.anandtech.com/bench/Product/697?vs=434
It's a significant improvement at stock thanks to a higher clock and a little better IPC.
I have an H100 on the way and I will report my findings when it gets here!
I agree entirely but to be fair you really have to compare a stock 8350 to a 8150 OC'd to 4 ghz. The 8150 has a stock speed of 3.6, turbo 3.9 and a few core oc to as high as 4.2 while the 8350 starts with all cores at 4 and, correct me if I'm wrong, but turbo of all 8 cores to 4.2.http://www.anandtech.com/bench/Product/697?vs=434

8320 is a good chip but from what I read the 8350 seems to OC better than when you compare the 8120/8150.
I really think where the 8350 shines is that at stock it is already 4ghz/turbo 4.2 Ghz. I think AMD pushed this stock chip higher and added a lot of very small tweeks. Considering the underlying Bulldozer/Piledriver design AMD did refine the chip to produce a decent CPU for both gaming AND multi threaded apps. Some may call me crazy, but even the Bulldozer 8150 was okay, just very unrefined. I decided to stay with the OC that resulted from me running it in the BIOS of my Sabertooth 990FX Rev1 mb. It set the multiplier at 200 and the fsb between 216 and 217 resulting in a modest OC of 4.334 Ghz. The best part is all voltage settings are stock and it runs nearly as fast as my high end OC of 4.7 but without all the voltage/heat/power increase.

I hear you. Most of us who overclock are tinkerers at heart!I think you are correct, there is a long thread at overclock.net on Vishera, not sure what to make of the chart on the first page. It shows both 8350's and 8320's overclocked with some of the settings used including voltages. From the charts I'm not seeing a huge difference in the two, but from the body of the thread (over 400 pages) the consensus seems to favor the 8350.
I don't game at all, and I got the 8320 for $162 total so I'm sure it will be fine for me, not really looking for huge clocks anyway - something new to play with is all.

Spend the time in school. It will pay off in the long run. I remember the "dark ages" of college, then grad school (69-76).Huh and here I was going for the 8320. I think I'm still going to stick with it since I don't like to keep my overclocks that high anyway, but I'll post what the highest I get is. Sadly I haven't ordered it yet because school is keeping me busy, but by a couple of weeks I'll let you all know.

Funny that you asked. I have Gskill DDR3 1866 ram but it runs just as good at 1600. However, OCing the FSB at 1600 setting gives me "headroom" up to 1866 safely. My Sabertooth Rev1. mb has a Auto OC function in the BIOS so I let it do an Auto OC with my 8350 and guess what? It Choose 20 multiplier and 216 FSB! Everything ran solid at stock 4.334Ghz. I thought "what must I tweek to get to 21 x 216 FSB solid? On my mb it required upping the vcore to 1.44, setting the LLC to ultra high, disabling the power saving features, enabling the full power phase and some other tweeks. It has worked well. It is Rock solid.I have read quite a few conflicting opinions on raising the fsb on these chips. I always raised it with my Denebs and the Thuban that I used. What is your experience? Any real reason to raise it or change the HT settings?
Edit: Actually pleasantly surprised with this 8320, haven't done much with it yet but, at the same speeds as my Thuban, it runs cooler and uses less voltage.
