As expected, Advanced Micro Devices on Tuesday updated the family of its highest-performance desktop central processing units. The new FX chips utilize new Piledriver micro-architecture and operate at higher clock-speeds, thus deliver about 15% higher performance compared to last year’s FX products.

“Gamers and PC enthusiasts who buy AMD FX processors have even more to cheer about with the increased speeds and value we are delivering starting today. After introducing the industry’s first and only eight-core desktop processor last year, we now have even faster stock frequencies and an all-new, high-performance x86 core architecture to satisfy power-users,” said Leslie Sobon, vice president of desktop and component products at AMD.

AMD FX "Vishera" central processing units sport up to eight Piledriver (second-generation Bulldozer) x86 cores with 1MB L2 per core, dual-channel DDR3 memory controller, 8MB L3 cache, Turbo Core 3.0 dynamic performance boosting technology and new instructions. Piledriver’s Front End now has a more precise branch predictor and a larger instruction window. The execution units acquired an enhanced scheduler and learned to process individual instructions faster, such as integer and floating-point division, for example. Moreover, the developers claim that they have increased the L1 TLB size and improved the data prefetch and arbitrating algorithms in the L2 cache.

Piledriver x86 cores use a new resonant clock mesh technology developed by Cyclos Semiconductor, which allows to cut power consumption by 10%, or boost clock-speed by 10% (compared to Bulldozer) without increase of TDP. As a result, AMD FX-8350 is the first multi-core desktop chip to officially conquer 4GHz clock-speed milestone, something that took many years to achieve. Thanks to the new technology, one can expect AMD’s team of professional overclockers to achieve never-before-seen 9GHz frequency (current record is 8.7GHz) with the new FX-8350 models.

The new AMD FX chips are compatible with AM3+ infrastructure as well as Scorpius platform featuring AMD 990FX core-logic sets. Given their higher performance out-of-the-box as well as potential for development, owners of AMD’s FX chips from last year should consider an upgrade opportunity.

While AMD put a lot of effort into improving the Piledriver and Vishera, due to general limitations of the Bulldozer-class micro-architectures, the new chips cannot offer performance comparable to Intel Corp.’s Core i7-3770K as well as Core i5-3570K “Ivy Bridge” microprocessors. As a result, AMD has to sell the new products at lowered prices between $122 and $195.

AMD positions its FX series for gamers and enthusiasts in budget, who cannot afford more expensive offerings from Intel. Considering the fact that performance in modern video games mostly depends on capabilities of a graphics processing units, such approach is completely justified.

Anton, please do something about the diarrhea jmlxg and AvonX keep spewing all over any article with AMD in its name. This is very unprofessional to have such comments in a technology discussion. If we are going to have a proper discussion, people need to keep it clean. If there is no regulation of comments on a place like this, it is a target for abuse.

In regards to jmlxg and AvonX - he/she is the same person who also posts to Fudzilla under the name Jesse Lee. This person either has a mental illness, a personality disorder, an autism spectrum disorder (Aspergers) or is paid by Intel to post rabidly on these influential tech sites.

No, that would be beenthere (you know, the one with the autism).

Many aspergers are IT people. Someone with asperger syndrome means that their interests are minute, but to what they are interested in, their interest exceeds to an extreme degree. You won't find someone with better knowledge on a specific subject than one with asperger syndrome. I have asperger syndrome myself, as do many within my field. I know a few others within IT who have autism, and they are the best at their job than any regular Joe. Therefore, it isn't wise to brush off people with autism with a negative connotation, but it a highly desirable aspect for someone looking to hire IT personnel.

I agree with everything you say mmstick. But a feature of Aspergers is sometimes a pathological obsessiveness - that's where I was leading. I often work with patients with Aspergers. You might enjoy the English comedy called Doc Martin. He is a doctor with Aspergers who is a very good doctor. His only problem is that he is a little blunt/ frank in his interactions with patients. He also doesn't understand that a very beautiful woman, a local teacher, is in loves with him. She constantly pursues him only to fail at the last hurdle because he can't pick up her innuendo or read the situation very well. It makes for really funny humour. But it is also respectful of people with Aspergers.

So what AMD has achieve to clock their processors to 4 GHz and above. That amount of speed and lower performance compared to Intel processors does not compensate for anything. It would of been nice if AMD took a risk and engineer these FX processors with a lot more oomph. Probably if AMD did this, people will consider buying AMD processors and I do not have to be sad to type this. A $200 for the top processor from AMD and it still can not compete. AMD is really ruin their FX brand for their enthusiast processors. AMD should think of concentrating resources to either APU or FX, but not both. Both will spread AMD's resources too thin and resources is already too runny since AMD already kick out more people and the most important people the engineers.

I used to come to xbitlabs for the usually insightful and in-depth comments. This is no longer the case.

You need to moderate the comment section or you will lose your readers, it is as simple as that.

You could contact the CEO of the site. But in reality, this guy or girl would probably come bounding back under several different user names again. I agree, they need to moderate this section actively. This is what happens in the real world where antisocial behaviour is handled by the law/police or by social exclusion/ restricting access. If we were in a group talking in a room, we would have thrown out AvonX / jmlxg and locked the door a long time ago. But here in cyberspace we have our hands tied.

I agree, too many people here voicing their mind with out the thought of Netiquette. For those people if you have nothing better to say, do not say it. That is just manners on the Internet.

AMD this thime delivered what they have promised. 8350 is a good cpu. What amd lacks is a overall fastest cpu when compared to intel, fx x4 is faster than i3, fx x8 is as fast as i5 and then intel has i7, thats good for them. Unless you are buying core i7 everyone should reconsider amd.

Newegg always charges 20+$ above the AMD price on launch since they are popular and there is always high demand for new processors, they can get away with it due to demand and loyalty to newegg. It might take a bit longer, but within a month you should find AMD prices everywhere. The AMD price is what they suggest retailers to sell them at, not that they have to comply.

Even less reason to buy AMD's CPU's. They are only popular with people like AMD too much. Intel is a better value its faster and uses less power.

Please, do tell. How does retail prices on launch have anything to do with AMD, Intel, or anyone for that matter?
