If rumors are true BD will show up in April. Motherboards should be out by then too, but considering the chipset is pretty much a minor refresh of the current ones I'm kinda surprised they aren't out already.

Stuff like media encoding is what the GPU is supposed to be used for at some point, its the whole APU/Fusion thing they've been talking about for years and years. Looks like the hardware will be there but I dunno about the software.

Either they'll beat it somehow in performance (unlikely) or they'll kinda close and sell it for less (way more likely). Still no word on pricing though and all we have for performance is some shady rumors and JF's statement that it'll have higher IPC than PhenomII. Supposed to be some sort of conference AMD is gonna do in late Feb. Should have more info. by then.

Yea, whole thing smacks of "something went really wrong but we're not gonna say what". At this point I'm expecting more delays for BD, which is really bad for AMD. e: Also this is apparently fake info. on BD.

Thread's been dead for a while but then there hasn't been much good info. for a while either. That seems to have changed in the last couple of weeks. We seem to be getting current 8xx chipset based boards that can support BD coming soon, in April. The mobo shown looks like a high end exxtreme version that'll cost probably north of $200, but hopefully they'll have some more sanely priced versions out too. This is kinda old now too but hasn't been brought up. Looks like we can expect some 3.5Ghz 16 thread BD's that'll fit in the same power envelope as current 12 thread Opteron's running at 2.6Ghz or so. Turbo supposedly might add another 500Mhz or more to that, but no word on the power/work load requirements for when/how Turbo kicks in or how many cores will use it at a given speed. Still no word on per clock performance though. e: 9xx is supposed to be a minor refresh of the 8xx chipset, much like how the 8xx chipset was a minor refresh of the 7xx chipset. Best you could hope for is better performance with SSD's and PCIe performance but its not clear if we'll get even that.\/\/\/\/\/ PC LOAD LETTER fucked around with this message at 16:02 on Mar 1, 2011 |

Nothing BD related though there is a nifty quick n' dirty video demo of Llano that was done recently. Will get whipped soundly CPU wise of course by SB, but the video showed it getting around nearly double the fps in games while using around 10-20w less than a 2Ghz quad core SB part. No clue on clockspeed or pricing yet, but its a AthlonII derivative so clocks/performance will likely be similar at least.

adorai posted:Not bulldozer, but question relating to the new poo poo from AMD. Per clock, can I expect similar performance between an ontario/zacate/llano platform as I can get from PhenomII/AthlonII? I am considering replacing my fileserver, which is currently a 45W AM2 Athlon x2 1.9GHz. If I can replace this with an APU that consumes only 18W, and not have to worry about performance, it's worth it to me (my office has terrible air flow and it gets warm in there). If it goes well I might even replace my VMware server as well (Athlon X2 2.5GHz) since it rarely caps out. Zacate/Ontario is around 10% slower per clock than AthlonII. Llano will perform nearly the same as AthlonII per clock since its the same core but shrunk down to 32nm. The Llano used in the demo I linked a ways up the page was apparently a 1.8Ghz dual core version FWIW. greasyhands posted:The only time they've ever been "real strong" was due to intel's colossal misstep with the pentium4. Looks like AMD has finalized the shipping date of BD and Llano, so no more rumors, late June (20th) is the shipping date. Given the "FX" branding the chips are getting these will probably be high end expensive parts. Which is both good and bad I guess. Good because AMD has something that may compete with Intel's best, bad because they'll probably price it accordingly. Oh well, they'll still have to contend with the ~$200 i5-2500K somehow so I'm guessing they won't go too crazy with the pricing.

They aren't out yet so its possible that may be why they aren't listed for comparison, no prices and such. That being said the socket 1366 CPU's aren't listed either. We'll have to wait and see as usual to know for sure. And some more leaks. If this and the other slide are correct that means we can expect a quad core Llano with 320-400 SP's to sell for around $150-200 for the highest end model. The lower end dual core and 160 SP models will probably go for around $100. Bear in mind you'll need a new socket/mobo (socket FM1) for Llano to work. Still seems like a good deal if this pans out.

I know on the very low end prices seem about right for the whole PC new. Sub $400 for a Ontario/Zacate system is pretty close to what they sell for right now for instance. Doing a quick and dirty check online at Tigerdirect and newegg i7 prices for the desktop actually seem to be around $50-100 higher than the $700 cut off on the chart and that is without the monitor. i5 system prices seem to be around $550-700 or so, also without the monitor. i3 systems are about the same price wise as the i5's. Sure there are some deals that will skew things either which way, but I don't think chart is off by much if it is off at all.

I think AMD always said that the new socket was to allow for TC2 and some new power savings options, which won't work if you put a BD into a AM3 socket. It was probably always technically possible, after all the north bridge doesn't have the memory controller anymore and the interconnect is somewhat generic now*, but for some reason AMD didn't want to do it. I guess ASUS decided to give it a shot, and you might not care about power savings and TC2 if you're gonna OC the thing anyways. *AMD uses HT as a bus between the North Bridge and CPU, the South Bridge connects to the North Bridge via a PCIe variant IIRC, which is why you can find 7xx chipset AM3 motherboards and 8xx chipset motherboards with the old SB710 South Bridge instead of the newer SB850 one.

Yea saw that. Didn't mention them because the test system apparently is configured improperly and/or is buggy beta hardware. 1 benches looked good, others were actually slower than Phenom II's. Doubtful that will reflect the final product since JF-AMD already said BD will be faster per clock than the "Stars" core.

Not much to talk about right now. Only new info. I've seen is that supposedly BD is now coming out at Computex. So early June. http://wccftech.com/2011/04/09/gigabyte-slide-reveals-amd-bulldozer-launch-date-launched-7th-june-computex-2011/ And yes the 8RDA+ was great. IIRC it had some of the VRM's on the back of the board which was weird and it used a different power supply spec, emphasizing the 3.3v rail, instead of the 5v or 12v rails like most PSU's. Caused it to behave oddly if you had a crappy PSU, but oh man was it good if you had a good one.

BD clocks just got leaked. Base clocks top out around 3.2Ghz and start at 2.4Ghz. The 900Mhz-1Ghz Turbo boost over stock clocks is quite nice, and its likely to be per module too, so 2 instead of 1 core would be boosted. JF has already said that they'll be able to raise the clocks up to 500Mhz on all cores while maintaining stock TDP for at least some models as well. edit: mhzzzzzzz PC LOAD LETTER fucked around with this message at 16:29 on Apr 28, 2011 |

And it looks like BD performance numbers have been leaked. The top BD chip is supposedly as fast as the i7 2600K which is pretty good but we still don't quite know its exact price yet nor how well, if at all, it overclocks. So its possible the i5 2500K or i7 2600K might end up being better buys over all, but still this seems like good news for AMD even if Intel has a big update coming 6 months or so after that.

I don't think there are going to be any 3rd party chipsets for AMD's chips this time around. Their in house chipsets aren't perfect but do seem to be good enough that no one tries to compete with them anymore. They could certainly still screw something up though. edit: looks like some specs for some up coming AMD 900 series based motherboards have been leaked as well. No prices but I'm sure you could make a reasonably close WAG on what they'll be based on ASUS's current line up.

Looking at how Intel configured SB (only ~10% performance improvement over Nehalem but around 20% less power usage) my WAG is they're going to emphasize power usage over performance. They already know good and well that most of their CPU's are overpowered for what most people need to do with their computers and they're going to have to compete with ARM in laptops and servers somehow. AMD's, well GF's fab tech is based off of what IBM has IIRC, which is actually part of a whole group of companies working together to share development costs of the process. I don't know what they're planning re: FinFET's either. edit: Kanter at RWT recently did a article on Intel's FinFET's you guys may be interested in. One of the relevant tidbits in it was that GF/IBM were planning on using FinFET's when they get to a 14nm process. They appear to be shooting for a late 2015 launch for that process. I somehow doubt that they'll be able to avoid some delays or even pull that date in earlier so I think it wouldn't be unreasonable to expect a 14nm chip using FinFET's from AMD until early 2016 at best. It'll be interesting to say the least to see how AMD tries to compete when Intel will have such a huge advantage for so long. One option would be to use FD-SOI I guess since that may be available if not now then much sooner than 2015, but Kanter mentions that would increase costs by 10%. AMD has gone the SOI route before though when others wouldn't due to reported cost issues, so we'll have to wait and see... PC LOAD LETTER fucked around with this message at 01:39 on May 9, 2011 |

Space Gopher posted:TDP isn't a great way to look at power consumption and battery life any more. It specifies a sustained maximum power draw, but it doesn't give you any information about how the chip performs with lighter loads. Intel's current Sandy Bridge mobile quads have high TDPs, but still get excellent battery life under typical light-usage scenarios like web browsing because they're aggressive about clocking down, sleeping, and even gating off parts of the CPU that aren't in active use. It remains to be seen if AMD can match Intel's progress on that front, but I wouldn't assume that a 45W TDP automatically means poor runtime.

Its a drat shame AMD dropped the ball, again.  They're lucky they have a decent GPU to cram onto a single die with their older cores. Llano will make a good mainstream chip but that is a real disappointment to those of us who were hoping for something more than that.FPU though? I'd be surprised if the FPU was the problem. For what ever reason the problems seem to pop up with the L1 cache, decoders/schedulers with AMD.

x86 is pretty IPC limited, IIRC the Athlon had 3 decoders and only averaged around 1.5 IPC thorough put. 4 is already overkill, adding a 5th would be a waste. Resources would probably be better spent on a bigger/faster cache or branch prediction or improving clockspeed. I don't believe memory bandwidth is an issue right now either, almost nothing seems to be limited by it for desktop workloads.

Supposedly GCN is big and hot compared to VLIW5/4 5xxx/6xxx GPU's so it won't be put on a APU until another die shrink or 2. No one is really sure about what the 7xxx will be exactly yet but it could very well be VLIW4's last hurrah before GCN shows up in 8xxx cards.
