Today AMD has released two new processors that address the AM3+ market. The FX-6350 and FX-4350 are two new refreshes of the quad and hex core lineup of processors. Currently the FX-8350 is still the fastest of the breed, and there is no update for that particular number yet. This is not necessarily a bad thing, but there are those of us who are still awaiting the arrival of the rumored “Centurion”.
These parts are 125 watt TDP units, which are up from their 95 watt predecessors. The FX-6350 runs at 3.9 GHz with a 4.2 GHz boost clock. This is up 300 MHz stock and 100 MHz boost from the previous 95 watt FX-6300. The FX-4350 runs at 3.9 GHz with a 4.3 GHz boost clock. This is 100 MHz stock and 300 MHz boost above that of the FX-4300. What is of greater interest here is that the L3 cache goes from 4 MB on the 4300 to 8 MB on the 4350. This little fact looks to be the reason why the FX-4350 is now a 125 watt TDP part.
It has been some two years since AMD started shipping 32 nm PD-SOI/HKMG products to the market, and it certainly seems as though spinning off GLOBALFOUNDRIES has essentially stopped the push to implement new features into a process node throughout the years. As many may remember, AMD was somewhat famous for injecting new process technology into current nodes to improve performance, yields, and power characteristics in “baby steps” type fashion instead of leaving the node as is and making a huge jump with the next node. Vishera has been out for some 7 months now and we have not really seen any major improvement in regards to performance and power characteristics. I am sure that yields and bins have improved, but the bottom line is that this is only a minor refresh and AMD raised TDPs to 125 watts for these particular parts.
The FX-6350 is again a three module part containing six cores. Each module features 2 MB of L2 cache for a total of 6 MB L2 and the entire chip features 8 MB of L3 cache. The FX-4350 is a two module chip with four cores. The modules again feature the same 2 MB of L2 cache for a total of 4 MB active on the chip with the above mentioned 8 MB of L3 cache that is double what the FX-4300 featured.
Perhaps soon we will see updates on FM2 with the Richland series of desktop processors, but for now this refresh is all AMD has at the moment. These are nice upgrades to the line. The FX-6350 does cost the same as the FX-6300, but the thinking behind that is that the 6300 is more “energy efficient”. We have seen in the past that AMD (and Intel for that matter) does put a premium on lower wattage parts in a lineup. The FX-4350 is $10 more expensive than the 4300. It looks as though the FX-6350 is in stock at multiple outlets but the 4350 has yet to show up.
These will fit in any modern AM3+ motherboard with the latest BIOS installed. While not an incredibly exciting release from AMD, it at least shows that they continue to address their primary markets. AMD is in a very interesting place, and it looks like Rory Read is busy getting the house in order. Now we just have to see if they can curve back their cost structure enough to make the company more financially stable. Indications are good so far, but AMD has a long ways to go. But hey, at least according to AMD the FX series is beloved!
More MHz for the Masses
AMD has had a rough time of it lately when it comes to CPUs. Early last year when we saw the performance of the low power Bobcat architecture, we thought 2011 would be a breakout year for AMD. Bulldozer was on the horizon and it promised performance a step above what Intel could offer. This harkened back to the heady days of the original Athlon and Athlon 64 where AMD held a performance advantage over all of Intel’s parts. On the graphics side AMD had just released the 6000 series of chips, all of which came close in performance to NVIDIA’s Fermi architecture, but had a decided advantage in terms of die size and power consumption. Then the doubts started to roll in around the April timeframe. Whispers hinted that Bulldozer was delayed, and not only was it delayed it was not meeting performance expectations.
The introduction of the first Llano products did not help things. The “improved” CPU performance was less than expected, even though the GPU portion was class leading. The manufacturing issues we saw with Llano did not bode well for AMD or the upcoming Bulldozer products. GLOBALFOUNDRIES was simply not able to achieve good yields on these new 32 nm products. Then of course the hammer struck. Bulldozer was released, well behind schedule, and with performance that barely rose above that of the previous Phenom II series of chips. The top end FX-8150 was competitive with the previous Phenom II X6 1100T, but it paled in comparison to the Intel i7 2600 which was right around the same price range.

Since AMD held their Analysts’ Day, we have not heard a whole bunch from their CPU division. The graphics side has been in full gear launching the HD 7000 series of products, and soon we will see the final pieces of that particular puzzle fall into place. What about the CPU group? We have heard about Trinity for ages now, but that particular launch is still months away. The last CPU update detailed the “K” series of unlocked Llano chips. What about Bulldozer? Is there a new stepping? How is GLOBALFOUNDRIES’ 32 nm SOI/HKMG progressing?
I don’t have all those answers, unfortunately. Since AMD proceeded to sack most of the PR team, our contacts have all but disappeared. Questions emailed to AMD are often not returned. Requests for CPU information (or samples) are ignored. Are these people just simply overworked, or is AMD clamping down on information? Hard to say. My guess here is that they are taking the philosophy of, “No news is good news.” If a company does not send out review samples, they do not have to deal with products receiving bad reviews. I am not saying that the FX processors are necessarily bad, but they do not match up well against Intel’s latest Sandy Bridge parts. At least AMD parts are priced appropriately overall for their level of performance. If we look at overall results, the FX-8150 does match up fairly well with the i5-2500K, and they both exist very close to each other in price points.
What we do know is that AMD has released two new processors into the market with the FX-4170 and the FX-6200. The FX-4170 is a new dual module (four core) 125 watt TDP part that is clocked at an amazing 4.2 GHz stock speed, and a turbo that goes to 4.3 GHz. This is the fastest consumer grade processor in terms of clockspeed, but it obviously is not the fastest processor on Earth. The original FX-4100 is a 95 watt TDP part at 3.6 GHz stock/3.8 GHz turbo, 4 MB L2 cache, and 8 MB of L3. The FX-6200 is perhaps the more interesting of the two. It has a base clock of 3.8 GHz and a max turbo speed of 4.1 GHz. This is a pretty hefty increase from the FX-6100 with its base 3.3 GHz and 3.9 GHz turbo. The 6100 is a 95 watt TDP part while the new 6200 is 125 watt TDP. The 6200 is a three module (six core) part with 6 MB of L2 cache and 8 MB of L3.
The last bit of news is that the FX-8120 is getting a price cut to put it more in line against the competition. The email that we received about this and the previous announcements was amazingly generic and fairly uninformative. We do not know the prices, we do not know the rollout schedule, and we have no idea how much the FX-8120 is going to be chopped. We have seen the retail market already cut the prices down on the FX-8xxx series. The high end FX-8150 was introduced around $289 but now it can be readily available for $259. Now that demand has dropped in the PC sector and AMD’s supply has caught up, it is no wonder we are seeing new SKUs and the lowering of prices.
My goal is to try to get a hold of some of these parts, as they do look interesting from a value standpoint. The FX-6200 is of great interest for many users due to the nice provisioning of cores, L3 caches, and speeds. Throw in a decent price for this particular product, and it could be a favorite for budget enthusiasts who want to stick with AMD products. The area where it does fall down is that of TDP when compared to Intel’s Sandy Bridge parts at that price point. The jump to 3.8 GHz base speed and 4.1 GHz turbo should make it very comparable in stock clocked performance to anything Intel has in that price range.
Overclocking could be interesting here, but since it is already a 125 watt TDP part I do not know how much headroom these products have. 4.8 GHz is very likely, but on air cooling I would not expect overclocked speeds to reach much more above that. Still, these are interesting parts and give plenty of bang for their price. Add in pretty mature support for AM3+ motherboards, and AMD still has a chance with enthusiasts. The only real issue that is looming is PCI-E 3.0 support for the AM3+ ecosystem. We have not heard anything about the upcoming (or is it cancelled?) 1090FX chipset, other than it is based on 890FX/990FX and should not support PCI-E 3.0. With AMD’s push for APUs, I would expect the upcoming Trinity parts to introduce PCI-E 3.0. AMD also looks like they will start funneling the enthusiasts towards FM2 platforms and Trinity based parts. While AMD looks to support AM3+ with Piledriver based cores, my best guess here is that AM3+ will be phased out sooner rather than later.
The next 6 months will be critical for AMD and their path moving forwards. At the very least we will have a better idea of where the company is going under the new management. I am still expecting some big changes from AMD, and if Trinity can give Intel a run for its money in terms of per clock CPU performance, then they could have a winner on their hands and adjust their roadmap to further exploit that particular product release.

AMD's $270 flagship processor, the 3.6GHz FX-8150 had a mixed reception as the hype which lead up to the release built up our expectations to a point that the processor could not live up to. Part of the disappointment has been blamed on the Windows 7 thread scheduler, which AMD described as not being optimized for their architecture, which lead to the release of hotfix files KB2645594 and KB2646060. TechPowerUp revisited their benchmarks to see if these patches effectively increase the performance of multi-threaded tasks; single threaded tasks are dependant on processor speed so they should be unaffected by the patches.
"After settling on the market, with all the quirks and bugs supposedly fixed, all the hype and disappointment blown away, we put AMD's FX-8150 under the scope. Benchmarks are done with and without the Windows 7 hotfix and in depth overclocking should resolve any doubts you have about AMD's flagship processor."

You've been waiting through years of rumour and innuendo but the day has finally arrive, AMD's brand new Bulldozer architecture is here. It is like nothing we've seen before in any chip based off of the venerable Athlon line, which has served dutifully for over a decade. Bulldozer takes AMD's vision of a dual core processor not as two cores sewn together, but more as Siamese twins which share vital resources and are so closely conjoined that you cannot truly say where one ends and the other begins. The Bulldozer core is exactly that, while only four Bulldozer cores exist they can handle eight integer execution units, and four shared 2 x 128 bit floating point/SIMD which is interpreted by your OS as 8 cores.
Implementing a new technology is not without its drawbacks. The Athlon/Phenom architecture has been perfected by AMD thanks to its long life, while the Bulldozer is brand new and they've already started polishing it into Piledriver which will we see in the not too distant future (especially compared to the wait for Bulldozer). That immaturity is shown in Ryan's review where he compares it clock for clock to a Phenom II. It gets worse when compared against SandyBridge as the Bulldozer can at most occaisonally equal the performance of an i7-2600K. The only saving grace is price when you look at heavily multi-threaded applications and there are not many out there.
However one benchmark cannot tell the whole story, which is why [H]ard|OCP released two reviews on Bulldozer which focus on different aspects of the chips performance. Start off with their look at the performance which will give you an idea of how the chip performs under normal circumstances with its power saving features enabled and overclocked with those features disabled. Then they head onto what most people are interested in, the gaming benchmarks. Theoretical and productivity software benchmarks are one thing but we've all got to have fun sometimes and for those moments the new FX chips don't look too bad at all ... unless you are a Civ V fan.
"Computer hardware enthusiasts have literally waited for years for AMD's Bulldozer architecture to come to market and we finally see this today in its desktop form, code named Zambezi, brand named AMD FX. In this article we share with you our analysis of Bulldozer's performance in synthetic benchmarks and desktop applications."

Bulldozer. Since its initial unveiling and placement on the roadmap many have called the Bulldozer architecture the savior of AMD, the processor that would finally turn the tide back against Intel and its dominance in the performance desktop market. After quite literally YEARS of waiting we have finally gotten our hands on the Bulldozer processors, now called the AMD FX series of CPUs, and can report on our performance and benchmarking of the platform.
With all of the leaks surrounding the FX processor launch you might be surprised by quite a bit of our findings - both on the positive and the negative side of things. With all of the news in the past weeks about Bulldozer, now we can finally give you the REAL information.
- Bulldozer First Release and the State of 32nm AMD Parts
- AMD Bulldozer Processor hits 8.429 GHz - New World Record!
- AMD Bulldozer FX Processor Benchmarks Leaked
Before we dive right into the performance part of our story I think it is important to revisit the Bulldozer architecture and describe what makes it different than the Phenom II architecutre as well as Intel's Sandy Bridge design. Josh wrote up a great look at the architecture earlier in the year with information that is still 100% pertinent and we recount much of that writing here. If you are comfortable with the architeture design points, then feel free to skip ahead to the sections you are more interested in - but I recommend highly you give the data below a look first.
The below text was taken from Bulldozer at ISSCC 2011 - The Future of AMD Processors.
Bulldozer Architecture Revisited
Bulldozer brings very little from the previous generation of CPUs, except perhaps the experience of the engineers working on these designs. Since the original Athlon, the basic floor plan of the CPU architecture AMD has used is relatively unchanged. Certainly there were significant changes throughout the years to keep up in performance, but the 10,000 foot view of the actual decode, integer, and floating point units were very similar throughout the years. TLB’s increasing in size, more instructions in flight, etc. were all tweaked and improved upon. Aspects such as larger L2 caches, integrated memory controllers, and the addition of a shared L3 cache have all brought improvements to the architecture. But the overall data flow is very similar to that of the original Athlon introduced 14 years ago.
As covered in our previous article about Bulldozer, it is a modular design which will come in several flavors depending on the market it is addressing. The basic building block of the Bulldozer core is a 213 million transistor unit which features 2 MB of L2 cache. This block contains the fetch and decode unit, two integer execution units, a shared 2 x 128 bit floating point/SIMD unit, L1 data and instruction caches, and a large shared L2 unit. All of this is manufactured on GLOBALFOUNDRIES’ 32nm, 11 metal layer SOI process. This entire unit, plus 2 MB of L2 cache, is contained in approximately 30.9 mm squared of die space.

Intel has held the performance lead for several processor generations now, and while AMD is still technically in the game for home theater PC and budget builds, many enthusiasts have moved to Intel for gaming and high performance computers. Many of those people have also held hope that the chip manufacturer would eventually come back strong and maintain some level of competition in the industry. As we move closer to AMD's Bulldozer launch (which seems to have been confirmed for October 12th), enthusiasts and reviewers alike are clamoring to answer a long awaited question: "will Bulldozer give Intel a run for its money?"
According to website Donanim Haber, enthusiasts’ high hopes may finally be realized. The site has posted several benchmarks results that indicate Bulldozer is not only cheaper than Sandy Bridge, but performs on par with Intel’s top end Sandy Bridge chips. In many tests, the AMD FX 8150 CPU’s eight core performance matches the multi-threaded (8 threads, 4 cores) performance of Intel’s high end Core i7 2600k processor.
In the benchmarks that the site performed, the AMD FX 8150 was tested against the Intel Core i7 980X for 1080p gaming and the Core i7 2500k and 2600k for multi-threaded performance. In the graph shown above, the AMD Bulldozer CPU was roughly on par with the i7 980X, trading wins in some games and providing a similar level of performance in others. The AMD processor won in the Metro 2033 and Lost Planet benchmarks, but was slightly slower in Civilization V and F1 2010. In AVP and Batman (among others), the two competing processors saw equal results.
They also ran several benchmarks using highly multi-threaded programs to take advantage of the many-core designs of the AMD and Intel processors, including WinRar 4, Handbrake, 7zip, and wPrime 32M. The eight core AMD FX 8150 Bulldozer processor was tested against both an Intel Core i5 2500k and a Core i7 2600k. The AMD CPU came out ahead in 7zip, wPrime 32M, and Bibble 5.0. It was slower than the Core i7 2600k in the WinRar 4 tests and slower than both the 2500k and 2600k in the ABBYY OCR10 benchmarks. In the other tests, the AMD processor kept pace with or was only slightly behind the top end Intel 2600k CPU.
From the leaked benchmarks (which you can read here), AMD’s new Bulldozer CPUs have made an admirable showing. Should these benchmarks hold true, Intel will have some serious competition on its hands, something that the company has not had to deal with in a long time. Whether Bulldozer will result in price cuts or ramped up production on the Intel side remains to be seen; however, the results are not going to be easy for Intel to ignore.
Stay tuned to PC Perspective for more Bulldozer news in the coming weeks.

AMD has not been too well received in the upper end of CPUs for quite some time now. Once Intel started pushing for performance with their Conroe core, AMD was forced to stay competitive in the mainstream market to survive and that is pretty much where we have been for the last 5 years. Also returning after a nearly 5-year hiatus is the FX moniker for AMD’s flagship products. According to leak(s) from Microcenter that floated past our desks we should see a resurgence of at least one of those two on October 12th, 2011:
"AMD is launching their new AM3+ FX series processors on 10/12/11. We currently have a number of AM3+ compatible motherboards in stock. These motherboards will support the new AM3+ FX processors as well as legacy AM3 processors."
Personally, I would shy away from the words "Bull" and "Dozer" in my product line.
Also from the memo we learned that the new AM3+ FX SKUs that will launch includes: FX-6100, FX-8120, and the FX-8150. The 6000-series parts constitute 6-core processors where the 8000-series parts constitute 8-core parts. To support those processors we shall see three Gigabyte motherboards, four ASUS motherboards, and four ASRock motherboards. Update Oct 1 @ 2pm: There may be more motherboards at launch but since this is a Microcenter leak it only considers their stock.
|ASRock||890FX Deluxe 5|
|ASRock||880G PRO 3*|
|ASRock||890GX PRO 3*|
Each of these motherboards will require a BIOS update to be serviceable though the leak suggests that the update would be performed by Microcenter themselves. If for some reason you have the board on your own you will need an older AM3 processor to perform the update. Also, the last two ASRock motherboards (asterixed) do not yet have a BIOS update for AM3+. AMD is expected to post an official blog about the topic on October 3rd at AMD.com.

Tagged: video, overclocking, FX, bulldozer, amd
There is a sub-culture in the computing world that is more or less analogous to the world of NHRA drag racing: liquid nitrogen overclocking. And if you are really serious, liquid helium. During a press event in Austin, TX in August to discuss the upcoming Bulldozer processor, a team of overclockers pushed the new architecture to frequencies well beyond safety and well beyond where they should be. Without giving away the whole story yet, AMD was able to set a new frequency world record...
Sami Mäkinen and his team hit 8.429GHz on liquid nitrogen and liquid helium with a near-production FX processor sample. This bests the reigning record of 8.308 GHz that was hit on a Celeron processor with LN2.
On August 31, an AMD FX processor achieved a frequency of 8.429GHz, a stunning result for a modern, multi-core processor. The record was achieved with several days of preparation and an amazing and inspired run in front of world renowned technology press in Austin, Texas. This frequency bests the prior record of 8.309GHz, and completely blows away any modern desktop processor. Based on our overclocking tests, the AMD FX CPU is a clock eating monster, temporarily able to withstand extreme conditions to achieve amazing speed. Even with more conservative methods, the AMD FX processors, with multiplier unlocked throughout the range, appear to scale with cold. We achieved clock frequencies well above 5GHz using only air or sub-$100 water cooling solutions.
I was in attendance for the event and have to say that group put on a spectacular show and anytime you can play with liquid helium running at near absolute zero temperature, it's worth paying attention! In fact, I put together a video of the event that you can see below and if you haven't participated or seen something of this nature, it is worth checking out!!
Now I need to temper some dreams right now - the chances of you or I reaching these types of clock speeds on the Bulldozer CPUs upon release are pretty close to nil. What was more interesting was the casual overclocking we saw pushing upwards of 4.8+ GHz without breaking a sweat and that is what we will be investigating with our review of the processor later this year.
Update: Here is the screenshot from the official HWBot frequency rankings as well as a different video created by AMD themselves summarizing the event.
