Are we talking of multithread/multitask or of single thread/serial code.??.

Seems once something doesnt suit your spining theories you have
to bring again the single thread perf as the ultimate bench...

The amd fans are the ones who incessantly cite selective benchmarks where amd is slightly ahead and consistently ignore the vast majority where they trail, sometimes by a wide margin.

only intel fans feel the need to come into completely unrelarted threads and throw intel related benchmarks around.

We've all seen a thousand Intel vs. AMD cpu benchmarks... Most of us know the advantages and disadvantages of each, and if not that should be in a different thread. Can't we leave it be and just let IDC do his thing and talk about that? I'm still curious to see what he'll get out of this setup.

It s a given than intel s afficionados are always trolling and trashing
amd in any related thread , yet , i never see amd fans doing the same
in intels related threads , that say it all , and particularly for people
like you as witnessed by your riduculous and hateful post...

Of course , they will tell you that you re abusively using too much
multithreaded benchs , yet they will come with ten different games
as being ten differents and unrelated softwares.....

"We" is not the right term...

Idc made overclocking reviews of intel Cpus in other threads where
no amd afficionados came to trash the topic , so the "we" should
rightously be changed to "they"....

Hooray for confirmation bias.

hooray for completely missing my point:thumbsup:

No one cares about how right you are, go be right somewhere else and let adults discus what they what to discus without some know it all informing "us" of how wrong we are.

I'd argue that the majority — or at least the plurality — of system builders and enthusiasts are also gamers. So if you don't feel that games don't carry a lot of weight in a hardware discussion, you're delusional.

If haters would actually own an FX cpu they would find out they aren't crap and they aren't slow either.
True Revenger. When I first built a 2500k SandyBridge rig I said WOW this is fast and still feel the same way. I bought a Bulldozer 8150 because I had an AM3+ mb and despite all of the negative reviews it ran fairly well. The PileDriver is a nice improvement over the Bulldozer.

It truly is hard to convince some that the PileDriver, for its price, is a solid cpu.

what's your max stable clock on the cpu ?
Alias, I slowly keep upping the clock speed. The 4.6Ghz (219 x 21) is rock solid. I actually upped the cpu voltage slightly above 1.5 v and was able to boot into Windows 8 at 5 Ghz and run some programs but I would not consider it rock solid. With some more tweeks I think I could get my machine to 4.7 ghz Rock Solid.

What's funny is that the Intel SB chips I have, 2500ks, are rock solid at 4.5Ghz (103 x 44) but get a little shakky if i go to 4.7/4.8.

Again, stable for what? Some posters on these forums claim incredible OCs but in fact mearly get the machine to boot into Windows to validate. Not me. When I post an OC of 4.6Ghz (actually 4599) I can run any program at acceptable temps etc.

The PileDriver still uses more power than the SB/IB chips and throws off more heat as the OCs creep up into the high 4s (4.6 and above).

I'll keep bumping it up over time. I run IBT 20x, OCCP for 1 hr and AMD overdrive 1 hr to check for stability. Prime 95 has problems with the Bulldozer/PileDriver architecture.

I've been away from home, about 3000 miles away from home , the past week while visiting family for the holidays.

Good news is I now have another 3770k, so when I get "back to the office" and can do a better job of comparing the 2600k and 3770k to the FX-8350.

But not before I get on top of the FX-8350 OC'ing situation. I have yet to properly explore the OC'ing options for the cache or IMC, and I am still on the stock HSF.

In other words, I have barely scratched the surface with the FX-8350.

IDC: Bumped my fsb to 219 with multiplier remaining at 21. Effectively a 4.6 Ghz chip. runs well.

That is great to know :thumbsup: Do you mind just kind of giving me a data-dump of your particular specifics in regards to voltages, multipliers, and frequencies for pretty much everything?

In a way the Intel setups are vastly simplified, we just push the multiplier and voltage parameter and that covers 99% of the OC'ing opportunity. I recognize there are more parameters to be fiddled with on this AM3+ platform, which means I risk leaving performance on the table out of ignorance and I'd like to avoid that obviously.

you don't need to own the FX to get an idea of how it performs, there are hundreds of different tests available it's fast for MT (really fast for the money, core i7 level in many cases), IPC is lower but with high clock it's decent/good for ST (core i3 level in many cases), and the power usage is high compared to Intel, did I get something wrong?

I don't see people calling "crap and slow" here, just the "hater" guy...

it's a solid CPU depending on your use sure, as any other CPU can be, that's why relatively small differences or disadvantaged gain a lot of weight in these discussions,


I always considered a stable OC something which would have no issues with running something like linx for an hour, Prime 95 for multiple hours...

but I'm sure for some it's enough to run a game stable,

Well stable and "stable" are two different things . When you need your PC to do some serious work with some sensitive data(read valuable) I'd want to be 100% sure my OC is stable, for real. It's difficult thing to do since there is no real test to perform in order to be so sure. But a combination of several stress tests along with normal usage (day to day tasks) should be fairly close I suppose.

There's nothing "intellectual" , insightful, analytically unique or even down right worth while that you have posted in this thread. If you think my position is anti intellectual then I suggest you fit into the second half ofTrischmann's Paradox ^_^.

Given that:
I have a very good balance of work/life take responsibility for actually raising my children, have a reasonable amount of liquidity to offset my debt (let alone assets) and I don't over commit to things because someone else will let me. It seems to me if the US had more people like me then it might not be so financially messed up, unlikely yourself who's only note worthy addition it to shove your opinion down other peoples throats.

that's exactly what's needed!

But a combination of several stress tests along with normal usage (day to day tasks) should be fairly close I suppose.

I like my FX-8350. It is nowhere near the slow-performing fail-train that it gets made out to be in enthusiast discussions where second-fastest in benchmarks means being dead-last in perception.

Folks tend to get a little too binary in their categorization and characterization IMO. And I include myself in that generalization.

Until I had one to play with first-hand, I too had this impression that not only would a 4GHz bulldozer/piledriver consume 600W but it would also perform like an Atom processor.

But the performance gap just isn't that wide, and the power usage situation (once you factor in the power used by the entire platform, LCD included) just isn't that stark in contrast between the two.

If you game, you are going to be able to game regardless whether you bought a 2500k/3570k or an FX-8150/8350.

If you encode/transcode, you are going to be able to encode/transcode regardless whether you bought a 2500k/3570k or an FX-8150/8350.

One is better suited for a given application than the other, but neither processor type is so unbalanced as to be unusable or woefully underpowered as to prevent the user from getting done whatever task they are attempting.

I'm not just saying that to be a fence-sitter either, I'm using my 4GHz FX-8350 right after spending months using my 3770k @ 4.8GHz, which came after using my 2600k @ 5GHz and I do not personally notice anything being slower (nor notably faster) with the FX-8350 processor.

The power bill has not changed, the time for jobs to get done is roughly the same either way - if one is faster or slower than the other then it is all within my ability to notice or care.

I think as enthusiasts we get wrapped up, sometimes, in driving for the pinnacle of optimization when it comes to performance/dollar or performance/watt. Second best then becomes dead-last even though in reality second-best is virtually indistinguishable from "the best" in many usage scenarios.

It is a very "first world problem" type situation and debate in many of these arguments IMO.

IDC: Having some minor eye surgery today so I'll try to get my BIOS specs for my 8350 to you by Friday.

Yikes, hope it goes well for you and absolutely no rush on my account. I won't be back home until Friday anyway and even then I've got a bevy of other tests queued up to run through in the meantime anyways.

so have to tried any undervolting yet? it looks like yet again AMD are way to cautious ( maximize yield curve i guess) on stock volts. They where particularly cautious with Llano, people where getting stupid amounts of undervolting.

i have settled at 4.6 with 1.28volts, my "computer room" has

920- CO (@3.6) with a 6970 (very very hot)
8350 @ 4.6
X4 @ 3.2 with 4850
cisco 2821
cisco 3750
cisco 871
cisco 3502i

with no AC in this room and outside in summer 30-40C days, so this room gets very hot. I can run it @ 5ghz with + 0.025-0.050 volts ( my stock is 1.3) but in stress tests(IBT particularly) the CPU starts to throttle after about 3 minutes.

Interestingly i current have 2X4gig G skill ares 2133 ram in it, i went to add another 2x8 gig G skill ares 1833. no matter what configuration of memory ( single stick etc) i cant get to post with the 8gig sticks. using a GA-990FXA-UD3 so might be something to watch out for.

edit: my cooler is a budget thermal-take thermaltake Contac 39, so with a better cooler i would likely be able to make 5ghz stock in this room in summer, but the performance difference doesn't warrant the $70-$100.

with the FX 8150 my original impression was quite negative, ST as fast (or slow) as a sandy bridge Celeron, "heavy MT" as fast/faster than the i5, but using twice the power and priced higher than the 2500k originally,
but we are talking about more than a year ago,
now AMD have Vishera with a solid performance increase and better pricing,


I still think the "hardcore gamer" would easily spot the performance difference in games like Starcraft 2 and others, but overall I can fully accept that most of the time there is no obvious difference in using any of these CPUs, but we could also extend that to a good old overclocked i7 920 from 2008 and other CPUs, and pricing is so close between so many of the options that we end up using some "small" differences and decisive factors,



I think the built in Winrar benchmark is also a valid tool!?
Winrar is probably by far the most popular file compression tool, and it scales well with additional cores/threads

i can only speak relative to what i have used/built tested. 8350 in terms of heat doesn't seem noticeably different to the 3770 i just build. Compared to my X4 and my I7 920 it is leagues better.

on very serial dependent code( not just single threaded) where OOOE is limited and PD's front end overall not being that great, the raw IPC of SB/IB smashes PD. Outside of that it really isn't that bad, its the things that hurt serial code people notice the most, miss predicts, instruction decode, L1 write bandwidth ( boy did they mess that one up!!!). its probably only 10% of BD/PD deign that makes BD/PD "bad", which is a shame for AMD.

Agree with you on bulldozer. I was a little disappointed with it, but it wasn't as bad as people thought. I can't notice any difference between systems using Intel and AMD unless I'm running or looking at benchmarks. Even if I try out my old phenom II x4 that I have lying around, or the i7 ivy bridge and dual xeon computers at my college, they all feel the same. My 8120 left a little to be desired though. I would stutter in games for some reason and I'm not sure if it was my cpu or what, but the 8320 fixed that. Maybe my chip was a little unstable or something. I don't really know, but that problem is now gone.

I have fun overclocking these things but I'm trying to go for good efficiency in my setup, and so don't keep it overclocked. I don't really notice that big a difference between anything above 4GHz. That's just from "feel" though. Then again, I don't really use it for intense purposes (unless you count gaming) often. Benchmarks really do split too many people. If only everyone could experience both first hand for cheap. It's funny what such a small increase in performance and clock speeds did for this chip. I'm hoping for more from AMD's next generation, however that fans out, but I do love tinkering with this chip.

Keep on with your enslavement to confirmation bias — you're a textbook case. I actually have made intelligent contributions to this thread. You'll never accept that, however.

Quit with the "oh, Intel fanboys are persecuting us" sob story. It's childish.

Instead, address the arguments being made directly. Don't like that people are pushing single threaded performance? Try making a well-reasoned response as to why it's not important.

Good luck with that. You've got a pretty massive percentage of the desktop PC crowd that games.
