APU's aren't supposed to be faster than Intel's offering. It's supposed to offer great graphics performance at a lower cost. That's what APU is all about. Not to kill Sandy Bridge in processing performance, but to kill it in the mainstream area where graphics matter most.

regarding the 990FX

Arent most if not all bulldozer comes with ATI graphics? Why would AMD want to repeat Intel p67 mistake again? Shouldnt they just come out a chipset with vga support by default?
*
No. The first gen Bulldozer will not come with integrated graphics on die. However, the 990GX chipset should come with an IGP. The next generation of Fusion will be Bulldozer + Integrated graphics. Again, what's the mistake with Intel? P67 not allowing integrated graphics? AMD's case is not the same.

Bulldozer Turbo Boost allows 1GHz clock speed boost at maximum.

Llano is slightly faster to Athlon II, clock-to-clock comparison.
But still far slower than Phenom II with L3 cache.
Disappointing.  wink.gif
To AMD : The game is not changed.  laugh.gif

If you compare Llano with i5/i7, yes, it's pretty far off. But I believe AMD's target market with Llano is i3 and lower i5 which is the mainstream where most of the revenue comes from.

Now, I'm still waiting for reviews on AMD xfire with Llano before deciding on my next laptop purchase.

For mobile, The performance of Llano falls in between Arrandale i3-i5 + Radeon 5650.

It is interesting if it is priced below MYR2000.
It is excellent if it is priced below MYR1500.
It is a huge disappointment (or rather digging her own graveyard) if it's priced more than MYR2000 (considering there are better performance notebooks in that price range).
Now, it all depends on how AMD price the product.

Look at the price segment, AMD's Llano should be quite comfortable if it's priced < MYR2000.

Most of the revenue comes from MYR2000 segment?
AMD doesn't look "comfortable" to me.

Well, you're quoting retail price of laptops. AMD does not do retails. AMD only sells chips.

I reckon the A4 series notebook will be priced at around RM1.5k already.

The mobile APU is very good. But the desktop 1 is rather weak.

All along I'm talking about mobile. For desktop, maybe HTPC? But seriously, how many ppl build a rig just for HTPC? So AMD is probably trolling with Llano desktop until Bulldozer arrives

Yes, AMD don't sell finished goods but it still falls in the price game.

My point is, regardless of how each OEM prices their products, AMD sells the same, in volume. And if OEMs are clever in marketing, they can sell them on parity with current SB i5's (w/o discrete card) because of the graphics performance of Llano alone. Also, this may please the GPGPU crowd because of the on-die graphics performance. So it's actually a win for AMD this time around. People tend to place emphasis on the latest and greatest (namely Sandy Bridge) but when it comes time for purchase, it's always value for money, save for the enthusiast crowd.

How AMD sells in the same volume if there is no demand?

If the manufacturer sells Llano at MYR4000 (aka committing suicide), how many people will buy? How many chips AMD can sell?
My point is, AMD has to make sure it is priced in the right price too. Otherwise it just won't sell.
Value for money or not, it depends on the price.
*
AMD sells the chips to OEMs first, and then OEMs do the pricing.

Basically, AMD's demand comes from OEMs and it's up to the OEMs to make it competitive. AMD has little to no say in this. Much like graphics. They can only suggest a Recommended Retail Price, not dictate them. Although the thought of putting an insane price tag on the notebooks is beyond me, my point sticks.

As for the value for money part, you're repeating what I said. The point of it being value for money is very subjective. Everyone has a different perspective on what's of good value. Hence I said value for money instead of price. I bought an XPS 15 for my bro recently and it was priced insanely at 3.7k yet I took it as good value. That's my view.

It delivers great overall performance and stellar battery life as required by notebooks. Now I am wondering how their BD 8xxx would actually perform. I'm still undecided if I should pick up the C5F now or wait till the cpu gets launched. Are they supposed to be launched sometime in July? or was it supposed to be September?

Trinity APU uses Piledriver core and VLIW4 HD7000 GPU.
Here's the result.

We can see from above, Trinity SKUs has performance boost, increase 32% in 3DMark Vantage, 13.8% in PCMark Vantage compared to Llano SKUs.
The performance for crossfire-ing with HD6670 has nice performance boost too.

P/S : Calculated, Estimatedlaugh.gif

That's pretty good for low end market. Also, these are supposed to be Engineering Samples clocked to emulate actual products. If they are able to fine tune BD stepping B3 and give it a greater performance increase, I believe Piledriver may actually level the field against Ivy. Down to the end, price matters most.

AMD cancels 28nm APUs, starts from scratch at TSMC

Not good news for Bobcat which is still quite successful compared to other AMD products. They're cancelling 28nm GloFlo in favor of 28nm TSMC which is what they should have done in the beginning since the 40nm Bobcat was originally manufactured by TSMC. A lot of the problems with BD that is associated with poor performance, low yield and high power consumption can be traced back to how well GloFlo does with their design and if BD had been made under TSMC instead for example, the results could be totally different. If AMD continues with GloFlo for a 28nm Krishna/Wichita, Bobcat could it can possibly have the same fate as BD. Luckily all 28nm GPUs from AMD will still be manufactured under TSMC's 28nm process. AMD's luck improving performance lies with GloFlo improving their process node.
*
True. BD should've been clocked around 20 - 30% higher than current ones, but due to yield issues, it turned out a flop.

I don't like where AMD is heading, they had gone back to megahertz race. The common conception that 'AMD is hot' back during the Thunderbird era is going to be back because of this.

Although it doesn't matter much in desktop where you could put big cooler on them and reach very high speeds, but they won't appeal much for mobile gamer.

Just look at current AMD Sabine platform, with only 2.1GHz tops (with on our market it is usually have low based 1.4GHz clock quad core) it won't be able to perform in games because as we could see from similarly architectured desktop Deneb based Phenom II needs 3GHz and above to reach 25fps minimum, like for example Skyrim even with GTX 570 as per review here.

The only saving grace for AMD is because it based on k10 stars architecture people can use k10stats to overclock, some with modded cooling could reach 3GHz speeds as you could read here. Also Crossfire between integrated and dedicated GPU don't work in some games as well, lowering performance instead of increasing them.

I don't see how Trinity could be better than current Llano on laptop, the GPU could be faster, that's why its only 3D benchmark is been floating around, but what about the CPU? What are the clocks might be? With base clock of 3+GHz on desktop they better do something on mobile to make it appeal for gamers because high speed don't equal to low temperature or low power consumption.

AMD could do a lot of things with their Bobcat, really. Just put one in Ultrabook chassis and voila! Affordable Ultrabook.
*
There's nothing wrong with Megahertz race really, especially with current technology where die shrinks even smaller. Ultimately, fabs would come to a dead end, which was predicted to be at about 8nm or 4? I can't really remember. Instructions per clock cycles matter, the faster it is, the faster things get done. AMD is already some time ahead of what our current technology could handle, in terms of multi-threaded processing, based on BD. Sure, Sandy may seem faster on paper, but BD isn't a slouch either in terms of multi threaded processing. Give AMD some time to fine tune and GloFo to sort out their problems, PileDriver may just be the next true FX chip.

Have you seen tho, how BD perform under linux environment. Its pretty impressive some of the benchmarks. It gives a view of what happens when better optimisation is done. A window to what windows 8 would be....hopefully!
*
That's because Linux was able to make use of those "cores" which Windows 7 on the other hand treated like threads, similar to Intel's. In any case, it has been reported that Windows 8 would make full use of AMD's new arch. As for poor performance on Windows 7, I blame it on AMD. AMD could've worked closely with Microsoft in the beginning, but didn't, probably due to changes in the arch.

IPC don't equal to fast clock, what it should do is to execute instruction in fewer cycle as possible and done more work per clock cycle thus reducing the needs of high clockspeed and lowering power consumption. The reason why Netburst fails because they were aimed squarely at high clock instead of high IPC. It was predicted to reach 10GHz but where does it stop? Not even half of that. Check Netburst Rapid Execution Engine, it runs twice the clock as the CPU runs, which means Arithmetic Logic Units runs at 6GHz if the CPU clock is 3GHz but does it prove faster than lower clocked K8? AMD really needs to do another K8 to really gives Intel a run for its money. The situation is reversed now. Like I said high clock have huge drawback, mainly power consumption and heat. Other comes in the form of bad yield due to difficulty of manufacturing complex core.

By the time Pliedriver is out, Intel already have Ivy Bridge ready. Remember Intel have process node advantage over AMD.

Unfortunately hope alone won't helps AMD by much. But time will tell whether an improved thread scheduling in Windows 8 will improve its performance as most people hoped or not.
*
Precisely, I said nothing wrong with having faster clock if they can keep it cool. Because AMD has longer pipelines, essentially making its IPC lower, faster clock would make up for the loss. Yes, it was predicted to run close to 10GHz back in P4 era. I don't really mind the power consumption mainly because it's not 24/7, but I do care about the heat.

Another reason I said OKAY with faster clock was because I think AMD's cores race has come to a point of diminishing return where adding more cores would not necessarily provide better processing. Since BD's arch has longer pipelines, there's hardly anything they can do to improve IPC, which was why I said faster clock is okay to make up for the performance loss. Too bad, GloFo can't handle it.

Yes, it'd be interesting to see how PileDriver stack against Ivy. It'd be even more interesting to see how Trinity performs against Ivy. I don't really care about number crunching or benchmarking for that matter, what matters most is real world performance and pricing. Currently BD doesn't look too interesting to me because of its pricing. If they were to adjust it, lower by another RM100, it's a deal for me. I can make full use of those "cores", which would make i5 look like a baby.

Bear in mind that I'm talking about commercial, not servers.

It actually depends on what you're referring to. If you benchmark it with games, it'll likely be on par with 2500. If you benchmark it with video editing / compiling / archiving tools, it'll pull ahead of 2500, especially if scheduler done right.

Not quite on par overall, as the Core i7 990X was never a competitor to FX8150 (even the pricing is a telling sign). For example, you can check the results here: OpenBenchmarking.org - AMD FX-8150 Vs. Intel On Linux Benchmarks (quite a few others at OpenBenchmarking.org as well).  wink.gif

Bulldozer cores are really more like hardware threads since CMT is another type of multi-threading technology (like SMT or HyperThreading). It also has a few niggling issues (such as drop in performance) as found in HyperThreading with certain software or scenarios. Can be seen that in this new review: AnandTech - Bulldozer for Servers: Testing AMD's "Interlagos" Opteron 6200 Series (look at Rendering Performance: 3DSMax 2012 and Blender results on this page: Rendering Performance: Maxwell Render and Blender). And yups, Interlagos reviewed at last. hmm.gif

There are also reports that if programs were to be recompiled, they'd run a hell lot faster on BD.

Bulldozer was kinda of a letdown, especially after all those hype and the "record breaking" overclocking that they did. While Intel is not innocent of weird marketing (LGA 2011? Really?) at least they did not quite boast around.

But IMO the real problem is that AMD bit more than they could chew. They now look like they need to fight off competition from various fronts. But then again mobile computing looks like the way of the future, so who knows, their decision now might be the right thing for them in the future
*
Bulldozer ain't that much of a letdown if you really look at it as a 4 core, 8 threads product. Don't bring it to the gaming front. Instead, bring it to the productivity front and you'll be amazed how powerful a bulldozer really can be, going against an i5. Please, don't bring i7 into the equation, they are of different classes.

AMD's size, in terms of capital market is a fraction of Intel's. Obviously on the R&D front, they just can't beat Intel without some serious innovations. Fusion is a start and a right move and I do feel that their decision to leave the high performance market is justified because, how much more performance do you need or could fully utilize?

Enthusiast now what they want.  Thunderbird/thoroughbred was popular in retails. I bought them too. But not so in OEM vendor.

But ... but .... Prescott was a fail!

Anyhow, as for people who were saying BD was a fail, well, if you were to take a look at their earlier articles, you'd know that their initial plan was to launch BD above 4GHz at stock, which would definitely make up for some of the loss performance due to IPC. However, it was the yield issue that held BD back (this could be resolved if GloFo could get their act together). Then again, it isn't really much of a fail if you can really utilize all their cores. I'd still take a FX-8120 over an i5 Sandy any day. Then again, I hardly do gaming, it's for productivity. So to each his own.

As for some fellas complaining about BD as servers, they're actually quite fast based on AT's tests. However, do remember that not all the tests were recompiled to run on BD. Since it's a new arch, recompiling is necessary to take advantage of the new architecture. As for power consumption, keep in mind that based on performance per watt, BD falls slightly behind Intel's Xeon but it also costs less, the platform as a whole.
