On a not very technically reliable webcast today, AMD has announced that it will produce 64-bit processors based on the ARM architecture and combine them with the "Freedom Fabric" they acquired with the purchase of SeaMicro.

In a move that is incredibly telling about the times we are in, but not really a surprise to those of us that follow the processor markets closely, AMD and ARM announced a partnership beyond previously discussed in public.  AMD will start production of ARM-based processors in 2014 and will be among the first to include 64-bit technology. 

The target for these processors will be the server market and AMD hopes to be at the forefront the often discussed ARM-in-the-server-world migration.  While that server opportunity size is debatable, with partners on stage like Facebook and RedHat, there is little doubt that it will have an affect on enterprise computing in the next 24 months.  AMD is hoping that its experience with the move to 64-bit technology in the x86 migration will aid them in development and migration in the ARM architecture world; one that is currently still limited to 32-bit. 

UPDATE: As being reported by Anand Shimpi this is in fact NOT an architecture license but is instead a processor license.  What does that mean?  AMD is not going to develop its own core (as Apple and NVIDIA do) but instead will fully integrate an upcoming 64-bit ARM core in new AMD products.

SeaMicro's Freedom Fabric technology is another major angle that AMD has over other players in this field.  The fabric technology is meant to facilitate communication between multiple processors on a specialized bus, removing bottlenecks on the platform and network.  Dr. Lisa Su, SVP of Global Business at AMD, stated that simply connecting hundreds or thousands of ARM-based processors to each other isn't enough and moves the problem of computing management from the CPUs to the network itself.  Using Freedom Fabric, the AMD-based ARM processors would be able to much more efficiently communicate and thus maintain the promised power benefits of ARM servers.

AMD did state that they will continue to develop x86 processors going forward but you have to wonder about its dedication to that goal.  Working with ARM is a quick and easy way to get AMD into a growing market in the server world that Intel currently has no solutions for so it seems possible that this is simply a stop-gap until AMD can develop an x86-based solution.  It is hard to say for sure but for an organization in AMD's financial position, having options in multiple segments is certainly a good idea.

What you won't see yet is AMD's graphics technology in the ARM-based processors announced today.  This isn't an "ARM APU" but instead is a combination of SeaMicro and ARM for a very specific server workload. 

We'll have more on this announcement if anything else interesting is divulged, but you can find the entire press release from AMD after the break!

Piledrivers are elegant in comparison to Bulldozers

The FX-8350 Vishera processor from AMD has finally arrived with 8 fully unlocked cores of polished Piledriver processing power.  With Piledriver there are no huge changes to the existing Bulldozer architecture, this is more of a polishing and optimizing the existing architecture and [H]ard|OCP's testing bears that out.  While faster than the previous generation FX-8150 it still lags behind Intel's Ivy Bridge processors, disappointing but certainly expected.  The unlocked cores do lend themselves somewhat to overclocking, with [H] hitting a stable 4.6GHz with all cores enabled, a 10% jump in frequency.  At that speed it does better when competing with Intel's offerings, until you overclock them as well at which point the comparative performance suffers somewhat.

Make sure to catch Josh's review, covering both the 8 core FX-8350 and the $132 FX-6300 which has a disabled module; bringing back memories of older AMD chips whose modules could be brought back to life.

"AMD's new Piledriver core technology should not be a surprise to any enthusiast as much of its "embargoed" information has already been exposed on the Net. Today we take the AMD FX series model 8350 desktop variant, code named Vishera, and look at it in an enthusiast way as we expose its IPC at 4GHz, and a bit of overclocking."

Bulldozer to Vishera

 

Bulldozer is the word.  Ok, perhaps it is not “the” word, but it is “a” word.  When AMD let that little codename slip some years back, AMD enthusiasts and tech journalists started to salivate about the possibilities.  Here was a unique and very new architecture that promised excellent single thread performance and outstanding multi-threaded performance all in a package that was easy to swallow and digest.  Probiotics for the PC.  Some could argue that the end product for Bulldozer and probiotics are the same, but I am not overly fond of writing articles containing four letter colorful metaphors.

vish_01.jpg

The long and short of Bulldozer is that it was a product that was pushed out too fast, it had specifications that were too aggressive for the time, and it never delivered on the promise of the architecture.  Logically there are some very good reasons behind the architecture, but implementing these ideas into a successful product is another story altogether.  The chip was never able to reach the GHz range it was supposed to and stay within reasonable TDP limits.  To get the chip out in a timely manner, timings had to be loosened internally so the chip could even run.  Performance per clock was pretty dismal, and the top end FX-8150 was only marginally faster than the previous top end Phenom II X6 1100T.  In some cases, the X6 was still faster and a more competent “all around” processor.

There really was not a whole lot for AMD to do about the situation.  It had to have a new product, and it just did not turn out as nicely as they had hoped.  The reasons for this are legion, but simply put AMD is competing with a company that is over ten times the size, with the resulting R&D budgets that such a size (and margins) can afford.  Engineers looking for work are a dime a dozen, and Intel can hire as many as they need.  So, instead of respinning Bulldozer ad nauseum and releasing new speed grades throughout the year by tweaking the process and metal layer design, AMD let the product line sit and stagnate at the top end for a year (though they did release higher TDP models based on the dual module FX-4000 and triple module FX-6000 series).  Engineers were pushed into more forward looking projects.  One of these is Vishera.

Could AMD powered tablets firt in a sweet spot for those looking to pick up one of these new Win8 powered devices?  They will certainly be more powerful than an ARM powered WinRT tablet and the graphics will be superior to Intel powered tablets.  The Z-60 will have two 1GHz Bobcat cores each with 512KB of L2 cache and the HD 6250 GPU with 80 DirectX 11-class shader ALUs which should give snappy performance up to a 1920x1200 resolution.  The Tech Report talks about the various benefits and penalties to choosing a Hondo based device over an Ivy Bridge powered on in their article here.

amdhondoz60apu.jpg

"AMD is readying a new APU aimed at Window 8 tablets and hybrids. Otherwise known as Hondo, this Z-60 processor offers lower power consumption than AMD's existing APUs, and it comes with a side order of USB 3.0."

Intel Planning 10-core Xeon E5-2600 V2 Ivy Bridge-EP CPU

Subject: Processors | October 17, 2012 - 06:48 AM |
Tagged: xeon E5-2600 v2, lga 2011, Ivy Bridge-EP, Intel, 22nm

A recently leaked slide reveals one of Intel’s upcoming Xeon-branded server chips coming in Q3 2013. The Xeon E5-2600 V2 is an Ivy Bridge-EP processor and will be compatible with motherboards featuring the LGA 2011 socket.

Intel-Ivy-Bridge-EP-Launch-Roadmap.jpg

The Xeon E5-2600 V2 in particular has a 70W TDP (thermal design power) rating while the highest-end Ivy Bridge-EP CPUs will have TDPs of up to 130W. The E5-2600 V2 has 10 physical cores, and with HyperThreading it can handle a maximum of 20 threads. Each physical core has access to 256KB L2 cache and the chip has a total of 30MB L3 cache. Further, this (and other) Ivy Bridge-EP processor will support up to 1866MHz DDR3 system RAM.

Interestingly, the Xeon E5-2600 V2 is merely the middle of the road part for Intel. The company will be releasing processors that are even higher-end than this one. They will have up to 12 physical cores which means up to 24 threads. And paired with Intel's 22nm manufacturing process and 3D transistors, these chips will fit right into workstations and server rooms.

ASUS Maximus V Extreme-ly fast overclock.

Tagged: overclock, asus

ASUSTeK has just accomplished a new world record overclock with their ASUS Maximus V Extreme motherboard. They calculated 1 million digits of Pi in a time of 5s 94ms which beats the current best time 5s 125ms according to HWBot. This result once validated lands the Maximus V Extreme in the 1st, 2nd, 3rd, and 4th place positions.

ASUS has once again broke records in the Pi eating contest with their Maximus V Extreme motherboard.

It must be a fun day for an overclocker when you get to play with Liquid Helium. While I attended the Physics department of Queen’s University up here in Canada the facility was known for its condensed matter group. Much of the building was fitted with piping to recapture and recondense the Helium after its experiments strictly due to how much it cost and how rare it is. If someone offers for you to break an overclocking record with it you are obliged to say yes.

The achieved overclock appears to be tuned towards the application. Memory frequency was kept at 1333 MHz with a FSB of about 110 MHz. I would expect this multiplier-centric overclock is designed to keep the overclock focused on sheer number crunching which Super Pi likely relies on over memory bandwidth. Perhaps reduced memory timings might even come in to play for applications like this?

ASUS broke a few records with their Liquid Helium attempt. As of time of writing none of these records have been updated to the HWBot leaderboard.

With Super Pi running to 1 million digits Asus and their team recorded a time of 5s 94ms -- 31 milliseconds faster than the current leading time of 5s 125ms. The current leaderboard already contains the ASUS Maximus V Extreme motherboard in Gold, Silver, and Bronze positions. This podium has already been well represented by the Maximus V.

When you cannot be satisfied with 1 million digits of pi you can run the marathon to 32 million digits.

superpi32M4min43.jpg

The most current record that I could find was set by a team sponsored by GSkill who achieved the time of 4min 44sec 609ms just a couple of weeks ago. ASUS and their team - which apparently has at least one member, “Smoke”, in common with the team GSkill assembled - also beat this record by almost 2 full seconds with a score of 4min 43s 0ms.

Finally, the real Trinity reviews arrive

The NDA is over and we can finally tell you all about the new generation of Trinity, especially the compute portion which we were not allowed to discuss in the controversial preview.  Part of the good news is the price, Legit Reviews found the highest MSRP is $122 for the A10-5800K and it is currently available, though at $130.  The performance increase from the previous generation is decent for multicore applications though not so much for single threaded applications, overall you can expect general computing performance in line with Core i3 but not Core i5.  Gaming on the other hand did show much improvement, especially with you compare the built in HD7660D to Intel's current HD4000 and HD3500.  You can catch Josh's review right here.

LR_a10-apu-fm2.jpg

"The internal testing from AMD that we can see above shows a 37% increase in the 3DMark 11 score between the first generation A-Series Llano and this generation of A-Series Trinity. While our numbers don't match their numbers exactly, our Llano system scored 1115 3Dmarks while the AMD internal testing showed 1150 3DMarks. Our AMD A10-5800K scored 1521 3DMarks while they scored 1570. The overall difference was remarkably similar, AMD is boasting an increase of 37% and we saw a difference of 36.4%..."

Trinity Finally Comes to the Desktop

Trinity.  Where to start?  I find myself asking that question, as the road to this release is somewhat tortuous.  Trinity, as a product code name, came around in early 2011.  The first working silicon was shown that Summer.  The first actual release of product was the mobile part in late Spring of this year.  Throughout the summer notebook designs based on Trinity started to trickle out.  Today we cover the release of the desktop versions of this product.

trin_01.jpg

AMD has certainly had its ups and downs when it comes to APU releases.  Their first real APU was Zacate, based on the new Bobcat CPU architecture.  This product was an unmitigated success for AMD.  Llano, on the other hand, had a pretty rocky start.  Production and various supply issues caused it to be far less of a success than hoped.  These issues were oddly enough not cleared up until late Spring of this year.  By then mobile Trinity was out and people were looking towards the desktop version of the chip.  AMD saw the situation, and the massive supply of Llano chips that it had, and decided to delay introduction of desktop Trinity until a later date.

To say that expectations for Trinity are high is an understatement.  AMD has been on the ropes for quite a few years in terms of CPU performance.  While the Phenom II series were at least competitive with the Core 2 Duo and Quad chips, they did not match up well against the latest i7/i5/i3 series of parts.  Bulldozer was supposed to erase the processor advantage Intel had, but it came out of the oven as a seemingly half baked part.  Piledriver was designed to succeed Bulldozer, and is supposed to shore up the architecture to make it more competitive.  Piledriver is the basis of Trinity.  Piledriver does sport significant improvements in clockspeed, power consumption, and IPC (instructions per clock).  People are hopeful that Trinity would be able to match the performance of current Ivy Bridge processors from Intel, or at least get close.

So does it match Intel?  In ways, I suppose.  How much better is it than Bulldozer?  That particular answer is actually a bit surprising.  Is it really that much of a step above Llano?  Yet another somewhat surprising answer for that particular question.  Make no mistake, Trinity for desktop is a major launch for AMD, and their continued existence as a CPU manufacturer depends heavily on this part.

AMD Vishera (Piledriver-based) Desktop CPU Pricing Leaked By Retailer

Subject: Processors | September 29, 2012 - 10:46 PM |
Tagged: vishera, piledriver, amd, am3+

Trinity APUs are not the only Piledriver-based processors that AMD will be releasing this year. Trinity is coming next month, but later this year AMD should be putting out Vishera processors based on Piledriver CPUs cores – and without integrated GPUs. And now, thanks to a retailer leaking details on its website, we now know some basic specifications – and more importantly – pricing.

For the uninitiated, Vishera is AMD’s next generation processor. It will use the existing AM3+ socket, and is built on a 32nm HKMG manufacturing process. Further, the CPUs are based on the Piledriver architecture which features a number of efficiency improvements over Bulldozer.  Thanks to the architecture tweaks, and Cyclos Semiconductor’s resonant clock mesh technology that reduces the amount of power needed to keep the clock frequency synced across the entire chip. The architecture tweaks result in improved instructions per clock (IPC), improved floating point performance, leakage reduction, AMD Turbo Core 3, and new FMA3, AVX, AVS1.1, AES, and F16C instructions among other improvements.

For more information on the Piledriver architecture, and where AMD is taking it with Vishera, read the “AMD: Vishera and Beyond” editorial we recently posted. Also relevant is our mobile Trinity (A10-4600M) review which gives some small hints at the kind of CPU improvements we can expect with desktop Piledriver CPU cores versus the previous generation.

According to eTeknix, the recently leaked information from Bottom Line Telecomunications includes clock speed, core count, amount of cache, TDP and pricing for four of AMD's upcoming FX series Vishera processors: the FX 4300, FX 6300, FX 8320, and FX 8350. The FX 4300 is a quad core processor clocked at 3.8GHz with 8MB of cache and a 95W TDP (thermal design power). It was priced at $131.62 on the company's website. The FX 6300 CPU brings the core count up to six, and increases the cache to 14MB. It keeps the same 95W TDP as the FX 4300 but is clocked at 3.5GHz and costs $175.77.

The FX 8320 and FX 8350 are both eight core processors and have a 125W TDP. The FX 8320 is a $242.05 part with 16MB cache and comes clocked at 3.5GHz. The FX 8350 keeps the same 16MB cache but is clocked at 4GHz and, as a result, costs more at $253.06.

The FX 8320 in particular appears to be a neat processor, and will likely be the more popular of the two FX 8000 series as enthusiasts will overclock it match (or exceed) the FX 8350 while paying the cheaper price (since the only thing you are really giving up with the lower-end part is clockspeed, and not cache)!

It will be interesting to see if the Piledriver-based chips are worth the price though, since we have yet to see independant CPU performance benchmarks for either Vishera or Trinity. The following table is the leaked information from shopBLT mentioned above in table form.

shopBLT Item # Manufacturer Part # Description Price
BPW4489 FD4300WMHKBOX FX 4300 QC CPU AM3+ 8MB 95W 3.8GHz Box $131.62
BPW4488 FD6300WMHKBOX FX 6300 6C CPU AM3+ 14MB 95W 3.5GHz Box $175.77
BPW4487 FD8320FRHKBOX FX 8320 8C CPU AM3+ 16MB 125W 3.5GHz box $242.05
BPW4486 FD8350FRHKBOX FX 8350 8C CPU AM3+ 16MB 125W 4GHz Box $253.06

Speaking of pricing, AMD will not only be competing with Intel's Sandy Bridge processors, but its latest Ivy Bridge chips as well, so pricing will be key to AMD selling its CPUs. In the following chart, we compared AMD's upcoming Vishera processors (based on the leaked information above) to Intel's latest Ivy Bridge parts. Because we do not know what the performancer of Piledriver will be, we matched up the Bulldozer CPUs to the Intel competition based on pricing. Essentially, we attempted to find the the Ivy Bridge CPU with the closest price tag to the Vishera processors' price. Intel's 22nm process has definitely given the company a leg up on TDPs, but you do get as many as twice the cores (and cache) with AMD for the price. The FX 8350 is an odd part in that it does not have a good Ivy Bridge equivalent, because there is no approximately $250 Ivy Bridge CPU. The next-closest CPU is the Core i7-3770 at just-over $300. Note that it may end up being that a lower priced chip will actually perform equivalently (or outperform) to the FX 8350 – we just do not know at this point and the only basis for matching these up for sake of comparison is price right now.

The Intel processors were chosen base on pricing and not performance per-se. Note that the i5-3550P does not include integrated graphics.

Another interesting match up is the comparison between AMD's next generation Vishera processors and its current generation Zambezi Bulldozer CPUs.

zambezi vs vishera.png

The FX 4300 cache number seems like the only oddity, but is based on leaked information above.

Assuming that the leaked pricing ends up being accurate, AMD has put itself in an odd position with Vishera. Across the board, the Piledriver-based chips are notably more expensive than the Bulldozer predecessors. The next generation chips are offering up higher clockspeeds – and in some cases – lower TDPs. On the other hand, they are coming in at a premium, and AMD is already facing stiff competition from Intel’s Ivy Bridge and Sandy Bridge processors.

AMD will really have to bring the promised performance improvements in order to move its Vishera chips at these prices. Performance is key, and unfortunately that's one aspect of Piledriver that we don't yet know beyond AMD's claims. Personally, I'm hopeful that they will deliver on the claimed efficiency tweaks and that Vishera will be a success. At the very least, it should offer a nice upgrade for owners of AM3+ motherboards.

After the Trinity launch, we should have more information on the the level of CPU performance we can expect from Piledriver. Keep an eye on PC Perspective for more information on Vishera and the Piledriver architecture in general as it comes in!

That's why it is called a preview not a review

Subject: Processors | September 27, 2012 - 07:53 PM |
Tagged: trinity, preview, papermaster launch, disappoint, amd, A10 5800K

By now you have probably realized that there is some commotion surrounding AMD's preview of their new Trinity chips.  As you can see below, many sites chose to post this preview as it is new information, regardless of the limits that AMD required reviewers to submit to.  Before you woke up this morning you did not have the knowledge you do now about Trinity's power consumption and gaming performance, for example Legit Reviews results, and on the 2nd you will get the rest of the results, which is not too far off in the future.

While limiting reviewers to a certain set of benchmarks for a preview is not a popular move for readers or writers, it is nothing new.  From Kyle's take on NVIDIA's reviewers guide to the driver wars which have gone on and on and on for longer than it is easy to find links for; there is a dirty side to reviewing.  Sometimes companies release new products and go out of their way to ensure that reviewers do not get their hands on before the products are for sale.  Of course reviewers occasionally go out and buy those products and once they get them on their test benches it becomes obvious why the companies did not send out review samples.  You don't have to like these practices, or accept them, but please realize that it is nothing new when you are lodging your complaints ... and do lodge complaints to the manufacturers if you find yourself upset.  Here at PC Perspective we want to give you all the information we can, even if it means we can only give it to you piecemeal, you do still get it.

"So far, it appears that these APUs have an advantage over Intel's Ivy Bridge processors when it comes to graphics. The new AMD Radeon HD 7000 series GPU in these APUs is clearly superior to the GPU found in equivalent and even more expensive Ivy Bridge processors. Additional tests will have to wait until October 2nd, as that is when AMD is allowing full reviews of the new 'Trinity' APUs..."
