    The APUs use the FX architecture now.

    I hope you're right, but I'll believe it when there's a little more hard evidence on the table.

    Ah well, the results were to be anticipated. The gains are slightly bigger than what could be attributed to just the clock increase, but not by much. It's what AMD had predicted for this revision and bigger gains are only expected with the future core tweaks.

    Still, that small increase plus a 11% speed bump means that AMD's top of the line just got slightly better value for money.

    the result is Okay.. for me as long as AMD can reach beyond 40 fps gaming in full hd... Games On!
    all i do really care is that i just wanna play some Games without breaking my ATM :D

    That hurts. :) But yeah it's nice to see the G2120 doing as well as I thought it would. Outside Battlefield 3 at least, which seem like it's optimised to really take advantage of four threads when available even if just by Hyperthreading. Could be a trend for games using brand new graphics engines, but I wouldn't expect to see any big numerical shift towards that too soon on the gaming market.

    AMD's improved FX line is a nice allround choice with extra price/performance value at things like video encoding, but anyone building a system specifically for gaming should look a second time even at Intel's lower end Ivy Bridge models.

    Was that a comment for me? Seems I've forgotten to update my specs, got a new 1920x1080 monitor now.. and I'm planning to get two more. :p

    Yes, and grats :D

    What games do you play? I found the 6850 pissed all over everything at 2048*1152, but then I never tried BF3.

    I did when I had it, but I've since sold it and gone back to my previous card (9800GTX+). Actually, for folding, both its performance and its power efficiency were worse than the 9800.

    ATM it's mostly just F1 2010 (No, I won't update yet) and I know, the 5870 is more than enough for that, FSX, Civ V, Sim City 4 (looking forward to 5) and some STO off and on.

    The system I have right now is enough but I kinda like building new stuff as well.. I mean, my HTPC can play many games with it's feeble Athlon II X2 240e and a HD6850. Still, it's always fun to have some headroom when that extremely demanding game shows up.

    There is one game I used to play a lot that I might go back to, and for that it doesn't really matter that much what gfx card I use, it's extremely CPU dependant so for that game alone I may go the intel route.. (WWIIOnline)

    Hey Craig or V3...

    you guys think you can do a review in about the same way with a G34 Opteron 6272 16 core (8 cores x2) Within a windows 8 Enviroment (sapposedly resolves the windows 7 issues with these cpus)

    I think it would be of GREAT interest.. specially if you get a dual socket G34 board and then do a test run of single cpu .. and a dual cpu (32 cores total) run.

    There is quite a bit of discussion about that and the hopefully soon to be released newer models which are to feature 10 core (20 core) models.

    Some people are picking these type of cpus up rather then the intel i7 socket 2011's.. and some are producing good results.

    It'd be interesting to somewhat do a compare and contrast. Not sure if this is a feasable thing to do, or if amd would be willing to help out. But after looking at the figures.. i think people are really quite unaware of the opteron 6272 through to 6278's capabilities. and reasonable value for it's overall potential power.

    Those chips are totally unsuitable for gaming of course (low clock speeds, low IPC), but great for encoding or server work. Xeons can work out better value even for those uses if you run 24/7, however, due to power savings.

    Actually the Xeons are incredibly expensive...

    you can build a machine that is as much as 1/6th the cost of a xeon solution with equivilent to better power conservation as well as speeds/performance.

    And the last few results under a windows 8 RTM release showed the 6272 performing extremely well under modern gaming and general use situation providing a very serioues bit of competition for intel's i7 3930k or 3960x solutions.

    But i'd like to see a little more in depth review. AMD is due to release a new socket with more functionality and better performance.

    I think it's worth investigating in an article just to put up some resutls next to the current amd offerings such as in this review.. and intels.

    There are some great reviews on Opteron vs. Xeon. Generally speaking, if an Opteron solution and a Xeon solution have comparable multithreaded performance, the Opteron system is using a bit more power. Of course Intel runs away with single-threaded efficiency to a much greater degree.

    This review compares Bulldozer Opterons with (much older) LGA-1366 Xeons in the same price category.

    Too many games are dual-threaded or poorly-threaded for me to believe that an Opteron 6272 could compete with a 3930K (or even a Pentium dual core) for gaming. The max turbo on the 6272 is 3.0GHZ. In games using 2 or fewer modules, gaming performance would be at most roughly 3/4 of an FX-4170.

    Various chips vs. 4170 in a poorly threaded game.


    Actually, for many uses, the older, 12-core, Phenom II-based Opterons are a better bet.

    Again all of which are based on using server OSes... not something like windows 8 Pro x64... which i haven't seen a review of really, mostly just things posted by other users which look pretty decent.

    Windows 8 RTM is the only version which can properly use the bulldozer cpu without being sevearly crippled like they are in windows 7 or earlier.

    And for 1000 bucks... the same price as what a 3930k + motherboard costs.... you can get a 6272 and a motherboard.

    I think it would be an excellent thing to compare the 2 systems.... taking into consdieration that the opteron boards are VERY limited, and aren't exactly built for overclocking or other speed factors.. BUT they do appear to put up a decent fight...

    Currently the biggest number crunchers for Folding @ home are being produced on the 6272's.... And having talked to a few people that own them, there game playing capabilities UNDER windows 8 is a whole new experience compared to windows 7.

    Windows 8 cannot force a dual-threaded game to take advantage of >2 modules. Given that an i3 and an FX-4170 perform similarly in dual-threaded games under Windows 8, I don't see how a 3930k (which would be faster than the i3) could outperform the Opteron (which would be slower than the FX-4170). So regarding gaming performance, the following explanations are possible:

    • Your sources are lying
    • Your sources are experiencing a placebo effect
    • Your sources only play extremely well threaded games
    • Your sources upgraded from some other platform with terrible single-threaded performance.
    But outside of games, I can tell you right now what happens when you bench a 6272 against a 3930K.

    Using max-turbo frequencies:

    We know how four 3.9GHZ Bulldozer AMD modules compare to 4 3.5GHZ Intel SB HT cores, because we know how the 8150 compares to the 2600K. In perfectly threaded, non-FPU intensive applications (the best scenario for AMD), they're about even.

    And we can work out how much more powerful the workstation equivalents are.

    (eight 2.4GHZ AMD modules)=1.23x(four 3.9GHZ AMD modules)*
    (six 3.2GHZ Intel HT cores)=1.37x(four Intel HT cores)

    (1.37/1.23)=1.11

    So in the best case scenario for the Opteron, the 3930K is 11% faster.

    In the worst case scenario for the Opteron, we'll be looking at poorly threaded performance, and comparing one 3GHZ AMD core to one 3.8GHZ Intel core. No contest, obviously.

    And this is all before we start overclocking the 3930K.

    However, Opterons are multi-socket capable. F@H especially comes into its own here, because SMP PPD scales exponentially with multithreaded performance. So the PPD of two Opterons is more than twice the PPD of one Opteron.

    If you don't give a flying f**k about applications that use fewer than 8 cores, dual-socket Opteron boards start to add up.

    Single-CPU Opteron systems only add up if you need the ECC, or other server features.

    *(8*2.4)/(4*3.9)=16/13=1.23....

    Windows 7 and previous versions of windows would try to force a game that uses 2 threads onto the same core.. (8 cores, but 2 reside inside the one)

    It would be like forcing every program that is dual threaded onto just one of the cpu cores of the modern intel i3.... the sucker is going to suffer while the other cores do nothing.

    That is only one of the contributing factors that is prevailent within the windows 7 and older enviroment. Windows 8 is sapposed to fix these "issues"

    It should end up sticking the poorly threaded program/game onto entirely seperate cores so that they actually can be used properly.

    See it's still being argued that the operton 62xx series cpus are just an 8 core cpu... but in truth they are a hybrid 16 core. Simply because now i probably got this backwards.. but i think there is only 1 FPU ... meaning only 8 FPUs total... (1 per die) instead of 2 like the other.

    If things are handled properly there is a significant improvement rather then jaming everything through on a single core.

    So i say.... lets find out... As i want to confirm one way or another if windows 8 plus the 6272 actually do as some people are saying it's doing.

    I'm aware of the issue, but everything in my previous post still holds. Single-threaded performance will of course be unaffected by this OS fix. Applications that take advantage of every core, which is what most of my previous post was about, will be unaffected also.

    On an N-core Bulldozer CPU, applications that efficiently use between 2 and (N-1) cores will see a performance improvement. But we've seen with Windows 8 testing of FX4*** vs. i3 that it's still not enough. Incidentally, there was a patch for Windows 7 which provided most of the same benefit.

    but one of the major complaints what was that single core performance was SERIOUSLY hindered due to the way things worked under windows 7... not only killing multithreaded opperations.. but due to the way windows decided to do things, but also killing single threaded...

    Again a reason i want to see.... as there is a lot of conflicting statements coming about and many of what i'm hearing with people slipping win8 on seems to significantly show improvement...

    Any single-threaded performance improvements in Windows 8 are unrelated to its handling of Bulldozer and/or Piledriver modules.
