Really Ryan? 8.429 GHz? … *Scoff* - New World Record!

Subject: General Tech, Processors | November 2, 2011 - 02:55 PM |
Tagged: overclock, bulldozer, amd

Remember back in September when Ryan was all excited about seeing AMD exceed Intel with their Liquid Helium-cooled overclock? 8.429 GHz bulldozed past the 8.309 GHz record set upon Intel’s Celeron and all rejoiced at AMD’s 130 MHz triumph. Well out with the old and in with the new: there is a new overclocking king and it goes by the name of -- well it is also the AMD FX-8150. That is irrelevant, however, as the new record (if validated before someone beats it too) has become 8.461 GHz.

Someone’s the new king in town… the current king.

The new world record was set by Andre Yang, an overclocked from Taiwan, with an ASUS Crosshair V Formula motherboard. Benchmarks were not possible as when you get overclocking to this level: successfully running CPU-Z just to query the specifications of a CPU is generally considered sufficiently stable to be qualified as an overclock. Do not be surprised if SuperPi blows a hole through your chassis. It was not stated which method of cooling was used to allow the processor to reach those specifications.

Better thread scheduling could really help Bulldozer

Subject: Processors | November 1, 2011 - 11:48 AM |
Tagged: bulldozer, a8-3850, thread scheduling, amd

Windows and to an extent other OSes are now familiar with Intel's HyperThreading and tend to be able to schedule threads in an optimized manner, but what about the eight 'cores' in the AMD A8-3850?  The Tech Report found a way to test this and the results are conclusive; Windows 7 is not optimized properly for Bulldozer.  The Bulldozer has two cores on each module, easy to see in the picture below.  By playing with the core affinity via the command line you can run benchmarks using specific cores, to test the impact clustering together 4 threads in two modules versus spreading out the threads to one per module.  As it turns out, there is a noticeable difference when you do set the processor to run with one thread in each cluster.

AMD Reports Q3 2011 Results

Subject: Editorial | October 28, 2011 - 02:27 PM |
Tagged: Q3 2011, ontario, llano, GLOBALFOUNDRIES, bulldozer, brazos, amd

Unlike Intel, AMD was unable to report record revenues.  What they were able to report was a small profit.  They also were able to show some growth above that expected by most analysts, and even those in AMD.  Earlier this quarter AMD warned that revenues might not be as high as expected, but in the end AMD seemed to have done ok.

The company had a gross revenue of $1.69 billion, which is well above the expected $1.66 billion many analysts were predicting.  Net profit for the quarter came in at a reasonable $97 million.  This is a big improvement from Q3 2010, which had a net income of -$118 million.  Being positive for a quarter is a big accomplishment for AMD.  Controlling costs as a fabless semiconductor company is a lot easier as compared to running multiple Fabs and researching and implementing next generation process nodes.  Margins increased to 45%, but are still a far cry from the 60% plus that Intel achieves.  ASPs are also down due to the large amount of low priced, 45 nm parts that AMD still sells.

The primary movers for the positive results for AMD are their lineup of APUs.  The “Bobcat” based APUs have been a success for quite a few months, and with their superior performance and features as compared to the competing Intel Atom series, AMD is making a tidy sum off of them.  The big winner in the APU sector is of course Llano.  The uptake on this processor in the mobile space has been tremendous.  AMD has seen a 35% increase in mobile sales, and when combined with the already strong Brazos/Ontario platform, AMD is finally a factor in the mobile market.  The only real issue in this market that AMD is facing is that of continued poor yields on Llano processors.

Bulldozing through Linux benchmarks

Subject: General Tech | October 26, 2011 - 09:15 AM |
Tagged: amd, bulldozer, FX 8150, linux

With the lacklustre performance we saw from AMD's new Bulldozer CPUs on Windows except in seriously multi-threaded applications; it is with a hopeful heart that Phoronix tests the performance of the FX-8150 under Ubuntu 11.04.  There are a lot of benchmarks to go through, from general performance to specific AMD-centric tests to those focusing specifically on multi-threaded performance and even a look at the bundled watercooler.  Read through the benchmarks they've run themselves as well as user submitted test and then realize that this is only the first of a series of articles they are working on ... so for now they hold judgment on AMD's newest product.

phoronix_8150.jpg

"Two weeks ago AMD introduced the Bulldozer FX-Series CPUs to much excitement, although many were letdown by the initial results, and it was months after showing the first Linux benchmarks of an AMD Dual-Interlagos pre-production system. In the days that followed I delivered some initial AMD FX-4100 Linux benchmarks when securing remote access to a low-end Bulldozer system running Ubuntu 11.04 (and there were also some Linux benchmarks from independent Phoronix readers), but then last week a Bulldozer kit arrived from AMD. The centerpiece of this kit is an eight-core AMD FX-8150 CPU, which is now being used to conduct a plethora of AMD Bulldozer benchmarks on Linux."

Intel Reports Q3 2011 Earnings

Subject: Editorial | October 19, 2011 - 02:29 PM |
Tagged: sandy bridge, Q3 2011, Intel, earnings, bulldozer, atom, amd

This should come as a shock to no one.  Intel made a lot of money this past quarter.  We again have seen new records in both gross revenue and net income.  GAAP revenue for the quarter came in at an astounding $14.2 billion.  Essentially that is the net revenue for AMD during a three year span.  Net income is again impressive at $3.5 billion.  In AMD terms that would be gross revenue for three quarters.  Truly there is a tremendous disparity between the two companies who are very bitter rivals.  It is no wonder AMD is starting to really fall behind.

All of the internal groups, except for one, have shown tremendous growth over the past year.  Notebooks have really lead the charge as of late, but both desktop and server markets have shown very favorable growth for the company.  Even the McAfee and Intel Communications divisions provided upwards of $1 billion to the bottom line.  The only area that Intel is lagging in is the Atom line.

intel_logo.jpg

When we look at the product offerings of Intel in server, desktop, and notebook markets we see they have a sizeable advantage in both process technology and performance per watt.  Intel has been shipping 32 nm chips for well over a year and a half.  On the desktop this has translated to modestly priced processors that have a much smaller die size yet comparable (and even superior) performance to the AMD products which are much larger in size and more expensive to produce.  On the server side we really have not seen AMD make any inroads since Intel took over that market in a big way once they released the QPI based designs which took away AMD’s last architectural advantages; HyperTransport and integrated memory controllers.

The tragic comedy that is Bulldozer

Subject: General Tech | October 18, 2011 - 09:07 AM |
Tagged: bulldozer, amd

It is hard to know exactly what to say about Bulldozer.  It is not a complete fail for in multithreaded applications it sits in between the performance of the i5-2500 and i7-2600, which it was intended to.  Power consumption at idle has been improved but not at load which hurts, but not as much as the poor single threaded performance which is far worse than we had hoped.  SemiAccurate traced the long 5+ year history of the Bulldozer to see where AMD went astray from the dream that was.  The length of the story is certainly a part of it, 5 years is too long for silicon to languish especially when part of the delay was due to problems with the 45nm process.  Read on to hear about the struggles AMD underwent to get this chip to market as well as what corners were cut, or at least rounded, to get the chip on shelves.

SA_Bulldozer_Excavator1.jpg

"The story of Bulldozer and why it does what it does, both good and bad, can be summed up as death by 1000 cuts. There isn’t really any high point to the architecture, nor are there any really low points. To make matters worse, there isn’t any obvious smoking gun as to why things ended up so, well, meh. What you can get now, what you should have been able to get, and what you will be able to get from this new architecture is a long and complex story. Lets get started."

Benchmarking Bulldozer and taking the GPU out of the picture

Subject: Processors | October 17, 2011 - 02:06 PM |
Tagged: bulldozer, fx-8150, crossfire, gaming

One of the questions we have been asking about Bulldozer is how much it effects game play performance.  We know that for non-multithreaded applications th FX-8150 falls behind the top SandyBridge processors and barely breaks even on heavily multithreaded apps.  That doesn't necessarily mean that it will lag behind SandyBridge in gaming as many games do not utilize the CPU enough to make a huge difference, though that premise needs to be proved.  Enter Tweaktown who have taken the top Bulldozer and SandyBridge CPUs along with three Sapphire HD 6970 video cards, and placed them in a Maximus IV Extreme-Z and  Crosshair V Formula motherboard respectively.  With that much graphical power, it is possible to see the performance difference that the CPU and the motherboard chipset have on performance.  Read on to see how Bulldozer fared.

"We've already provided a fair bit of coverage on the new FX-8150 CPU from AMD and it hasn't all been favorable for the team over at AMD. If you haven't looked yet, I highly recommend you check out our other pieces that cover the VGA testing side of things and my editorial Shi**y Marketing Killed the Bulldozer Star which has really gained traction over the last few days.

Today we test the video card side of things a bit more and see what goes on when we start to make use of CrossFireX on the 990FX platform. The 990FX chipset shows some good potential and it's going to be interesting to see what happens when we start to make use of all those PCIe lanes that are on offer."

Can't hide the Bulldozer

Not to imply that looking at more Bulldozer reviews is like rubbernecking as you pass an accident ... but there are some similarities.  While it might not be as great a performer as we were hoping, the chance to finally see AMD's new architecture is still a great thing.  A totally new way of looking at a CPU Core, a brand new style of overclocking and a processor that seems almost ahead of its time when you examine its multitasking capabilities is interesting even if it does not deliver the processing power that we hoped for.  Check out The Tech Report's indepth report to see what they thought of its performance

Bulldozer Impressions: That was... interesting

Subject: Editorial | October 12, 2011 - 05:45 AM |
Tagged: GLOBALFOUNDRIES, fx-8150, bulldozer, am3+, amd, 32 nm

Huh. 

I am pretty sure I am not the only person who has read these Bulldozer reviews (including Ryan's here at PC Perspective) and had that particular reaction.  Bulldozer was supposed to bulldoze the competition.  It turns out it barely outpaces its own predecessor, the Phenom II X6 1100T.  In fact, in terms of IPC, the older Thuban architecture gives it a sound thrashing when both are clocked at 3.3 GHz.  So why should I be impressed with this processor?

mb3.jpg

I guess the answer is… you shouldn’t.  At least not yet.  I distinctly remember back in November of 2007 being invited to Lake Tahoe to test and report about the first Phenom samples that were available for limited testing.  We were not allowed to take the samples home with their new AM2+ based motherboards.  When going over the results of the tests with Ryan (I was not part of PCPer at the time) we quickly saw that the 2.6 GHz Phenom was unable to keep up with the Core 2 Q6600 from Intel.  This was a little surprising, as we expected the original Phenom to clean house due to its very forward looking architecture (HT, IMC, beefier FP/SIMD units, etc.).  The original Phenom had its fair share of problems, to say the least.  TDPs were very high, there was the revision B2 bug that was solved in B3, and due to the 65 nm process it did not nearly have as much cache as was needed to make it a more efficient product.
