It's an open secret that AMD is not satisfied with GloFo's supply capability, given all the news of poor Llano yields.

Damn, now even CanardPC says Bulldozer isn't that good. Apparently it's only competitive against Sandy Bridge in multithreaded benchmarks, and poor in games. It did recommend the FX-8120 for overclockers, though.

On another note, Intel shill OBR is claiming these:
"AMD FX has many clocks/voltage plans. 1400/1700/2100/2500/3200/3600/3900/4200+ MHz with various voltages. Default clock is 3.6 GHz at +/- 1.3V. Turbo Core 2.0 needs voltage 1.41V for 3.9 and 4.2 GHz."
And apparently, power consumption for FX-8150 is comparable with i7 2600K.

That's what all those E8400 users told me when I decided to get a quad core back in early 2008.

I think it'll be the same thing again now.

The early reviews tell me 8150 is rubbish. But I never intended to get the 8150 anyway. Why bother when the 8120 is far cheaper and probably hits the same clockspeeds after OC?

Besides, you're not going to be playing games at 1024*768, nor are you going to care about the the framerate on those. We all mostly game on 1080p anyway.

If you overclock, the FX is certainly better than the 2400 in all circumstances. You're better off comparing with the 2500K and 2600K processors.

Also some other sos kicap:

Got to play with a review sample. Not mine. I'm not NDAed.

The figures above posed by w00key do seem legit, but they're worst cases. In most games, BD trades places with a 2500K, in my own Fallout New Vegas testing, it beat my Phenom II X4 (3.7 GHz) by around 20%. The 2500K beats my Phenom II by the same 20%.

It's hilariously overclockable. Jury-rigging the biggest heatsink I could find, a ~7 year old Coolermaster Hyper6+ (which doesn't fit AM2/3) hacked into a pretty cheap Gigabyte GA990XA-UD3, I got 4.85 GHz out of it. At that kind of clock, the 2500K was looking for its parents with tears in its eyes, losing out on single threaded benchmarks by 10% and multithreads.... well, it wasn't really funny anymore. I'll share with you this:

Code:
CODE
x264 encoding
1080p
BD 4.85        12:33
2500K 3.8      18:56
PII X4 3.7     21:30

720p
BD 4.85        8:40
2500K 3.8      11:01
PII X4 3.7     15:15


* I'd like to have overclocked the 2500K more, but I was limited to a pretty shitty motherboard which looked to be an Asus but had no identifying marks and Intel's stock cooler.
** x264 June 2011 used. VirtualDub passing through AVISynth to the CLI x264 binary. VD was using a MoComp deinterlace filter which scales linearly to, according to the author, at least 24 cores.

It's competitive. For some workloads, you're going to want Intel. For others, AMD at last can out-perform Intel. I didn't have a 2600K to test, but if I had, I'd imagine BD would have beat it.

Of course these are all overclocked figures. Blame contractual loopholes.

Edit: Oh yeah, not allowed to say which model BD I was playing with. Also, to address the below, I couldn't boot the 2500K box with a multiplier any higher than 38. Even with scary voltages. I blame the Hybrid-EFI BIOS or some quirk of the board.

So an 8-core FX CPU is 33% faster than a 2500K with a 27% clockspeed advantage.

I'm a sucker for cores. Might upgrade to 8xxx series once my Q6600 dies, if it is less than 180usd.

Guess AMD are back to the low and mid-end then(not that they ever moved from that position)...with them taunting that their BD is unlocked compared to Intel line.

Well, I decided to grab a Yorkfield quadcore instead of an E8400 despite it being weaker at games during launch. It turned out to be the better buy in the long run, as it still holds up well in most tasks till now.

Well, can't say a thing about the Phenom 9600 then though, the 65nm Phenoms lost to the C2Qs in every single way, worse off than Bulldozer vs SB.

QUOTE(dma0991 @ Oct 12 2011, 08:00 PM)
I was expecting this video to come out. laugh.gif
I think AMD can still turn out to be great someday if they get their priorities right and management in order. Not necessarily R&D is the only problem that is causing AMD's downfall but also the management seems lacking. At first the BOD fired Dirk Meyer publicly about not having a mobile strategy and most probably about BD as well. Then Rick Bergman fired as well by Rory Reed for not being progressive enough which I think is what escalated the problem even further. Had AMD not created comics, taunting gifts and some publicly leaked slides, I don't think it would be that bad of a shock to many.

I do really hope that Rory Reed can really turn AMD to gold like he did with Lenovo because it really needs a proper management and better management of R&D funds to somehow make a better product. It is kind of sad to see that AMD is doing a disservice to themselves by releasing a product that is underwhelmed by its previous. I don't think it would be that bad if it did looked better than Phenom II X6 at the very least. Anand has sum it up pretty well and we're already partially affected by monopoly and it is just going to get worse if AMD doesn't get any better.
QUOTE(Anand)
The good news is AMD has a very aggressive roadmap ahead of itself; here's hoping it will be able to execute against it. We all need AMD to succeed. We've seen what happens without a strong AMD as a competitor. We get processors that are artificially limited and severe restrictions on overclocking, particularly at the value end of the segment. We're denied choice simply because there's no other alternative. I don't believe Bulldozer is a strong enough alternative to force Intel back into an ultra competitive mode, but we absolutely need it to be that. I have faith that AMD can pull it off, but there's still a lot of progress that needs to be made. AMD can't simply rely on its GPU architecture superiority to sell APUs; it needs to ramp on the x86 side as well—more specifically, AMD needs better single threaded performance. Bulldozer didn't deliver that, and I'm worried that Piledriver alone won't be enough. But if AMD can stick to a yearly cadence and execute well with each iteration, there's hope. It's no longer a question of whether AMD will return to the days of the Athlon 64, it simply must. Otherwise you can kiss choice goodbye.

Lol @ the Intel snipe by Anand

I'm not sure why Bergman was fired though, considering he did so well turning ATI around after the R600 fiasco.

Maybe for Battlefield 3 the FX-8150 performs well, but for the majority of the games the Intel Sandy Bridge processors are still much faster. smile.gif But still for the i7 2600K to lose 5FPS when overclocked to 4.8GHz compared to stock speed, it doesn't seem right smile.gif.

Note that BF3 is quite difficult to benchmark identically due to the game being purely multiplayer right now. No similar test run can be done on different systems atm.

Look at the market segmentation, it is all screwed up (Zacate killed K125/K325/K625. Llano killed Zacate and Radeon GPU in notebook market).
*
K125/325/625 were meant to be replaced by Llano anyway, after all they were grossly inferior in power consumption. Llano won't kill Radeon GPUs: those Radeons still have buyers in Intel laptops, look at how many get purchased by Apple for MBPs and iMacs for example.

MSI is pleased to announce that OC Genie II on the upcoming MSI AMD 9-series mainboards will support world’s most advanced automatic overclocking. With just the a single push of a button OC Genie II not only increases your processor and memory speeds, it also unlocks up to 8 CPU cores. This makes OC Genie II the simplest option to increase your performance on a MSI AMD 9-series mainboard up to 250%. MSI’s upcoming AMD 9-series mainboards are built to the highest quality standards: MIL-STD-810G certified Military Class II Components. Military Class II components give you the best efficiency and highest performance on the upcoming AMD 9-series mainboards.

MSI’s 25 years of knowledge in mainboards and over clocking has delivered some remarkable results. With  the world’s first overclockable mainboard, which was a 80286, to the simplest ease for end-users to upgrade their PC performance up to 250% with a simple push of a button.

OC Genie II performs these tasks with a single push of the button:

- Unlock hidden CPU cores
- Adjust CPU clocks (up to 8)
- Adjust CPU multiplier
- Adjust CPU voltage
- Adjust memory speed
- Adjust memory voltage.


Sucks to be AMD, but I guess now nobody's going to even consider the FX-8150 right now if those FX-4100 chips can unlock the other 2 disabled modules.

Well, a lot of reviews said that the 8120 was already a better buy than the 8150.

Just a quick question: Is the integrated graphics on the AMD A8 3850 faster than a i3 2100K and GT 430?

so all we have to do is pray that its enough to make they operational smoothly for another development

I just hope there's that many people who factor x264 as the most important benchmark.....

We're paying the price for AMD's server first and only approach with processor design right now.

Northbridge overclocking appears to work well for games in Bulldozer:

See the Civ5 and MOH SP benchmark. Perhaps the MOH SP benchmark translates to other UE3 games too?

MSI rep's comments about the possibility of the Asus C5F sucking:
QUOTE
Actually, the benching we've done in-house did show some very bad scenarios in games, but generally the performance was right where it should be for the price.

The power consumption however, is a different story. it's not uncommon to at 50W or 100W extra for the use of an Asus board versus that of an other brand.

Graphics performance with an AMD graphics card is better than the same card on an Intel board and a BD can actually provide beter results in games/benchmarks than a i7-2600K. it just seems AMD didn't think this launch out quite as well.

If that's true, all the more AMD need to sack their marketing team for ruining their launch. They should have done their homework better for mobo selection rather than just picking the most expensive board off the shelf.

I'm not sure how PassMark gives scores but it could be influenced by overclocks, performance memory/SSDs for read/write tests etc.

2 possibilities,
A paid job or AMD processors are Passmark-optimized.

Look at the scores of Llano, especially the mobile Llano.
We know it has the performance of "Athlon". It's about the performance of Nahalem i5.
But the passmark scores show it is running as fast as SB i5.

I'm guessing Passmark factors in IGP performance then.
