Advanced Micro Devices has revealed certain launch plans for its next-generation FX-series central processing units code-named Vishera based on Piledriver micro-architecture to its partners in the channel. As it appears, the company is preparing three new FX family microprocessors to launch this year: a quad-core model, a six-core model and an eight-core flavour.

A leaked marketing document, presumably from AMD, reveals specifications of consumer-oriented chips that the company intends to release in the coming months, possibly early in the fourth quarter of the year. Apart from expected release of A-series Fusion "Trinity" accelerated processing units (APUs), AMD will also roll-out FX-8350, FX-6300 and FX-4320 central processing units (CPUs) based on "Vishera" design and featuring x86 cores powered by Piledriver micro-architecture.

Based on specifications of AMD FX-series "Vishera" processors published in the document, it appears that the new multi-core chips will not be clocked at significantly higher frequencies than the currently available AMD FX "Zambezi" CPUs. Given the fact that 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% without increase of TDP, the reason why the new Vishera CPUs do not feature increased frequencies is unclear.

A possible reason why AMD decided not to clock new FX-chips at high levels is that the CPUs have certain issues with operation at elevated frequencies for prolonged periods of time. Another reason is that AMD feels confident that advantages of Piledriver micro-architecture will grant sufficient performance increases to the upcoming FX-series products.

The document is dated July, 2012, therefore the plans might have changed since then.

AMD did not comment on the news-story.

Anton, you say that AMD haven't increased clock speeds, but if you look at the FX-4320 it has the same TDP as the FX-4100, but is clocked 400MHz higher. Same with the FX-8350, same TDP as the FX-8150 but 400MHz higher. Sure the peak clock hasn't increased substantially, but given the low performance/watt stats of Bulldozer, AMD has clearly chosen to take on the watt side of the equation as much as the performance.

When it comes to the FX-4320, it should be noted that it is 4GHz/4.2GHz@95W, whereas at the same time AMD offers FX-4170 (4.2GHz/4.3GHz@125W), which probably means either no improvement, or a very slight improvement.

You noted it correctly: for some reason, AMD decided to "take the watt side" (well said! ), whereas what it does need is performance. Why?

Those processors are cherry picked from the crowd. This isn't to say that AMD will never release a 4370 sometime soon after releasing the FX-4320. You are not thinking at all here.

Also, don't take genie's words out of context. Recall that he said, "as much as the performance."

We all know everyone is competing for watt consumption here, but any saved watt consumption is also spent in increasing frequencies of the higher end processors. Wait for the 125w variant of the quad core FX, however it does not make sense to not buy the 8 core variant.

keep in mind that FX-8350 and FX-8150 max turbo clock is same. Both are 4.2GHz

On this note neither did Intel with their Ivy Bridge launch. The 2600k has a 3.4ghz( 3.8ghz TB) stock clock with the 3770K at 3.5ghz(3.9 ghz TB). The 2500k is at 3.3ghz (3.7ghz TB) and the 3570K at 3.4ghz (3.8ghz TB). I know they focused alot more on TDP with the die shrink from 32nm to 22nm but the fact still remains the same

Did you even bother to read that chart Anton?

There are a lot of negative propaganda against AMD.Xbit also focus on workers who leave AMD.Such things do not exist for other companies.Neutral reader have impression that AMD is patients that will not heal.Who's behind it, you can assume that.So no matter that piledriver has success in the notebook market,we will always speculate negatively about AMD.

Do you even know what TDP means? AMD has CPU`s that are realistically 95w but are rated at 125w tdp. It could be for overclocking headroom, so motherboards don`t cheap out...

Yeah and Intel does this too. Your point? If anything AMD is worse than Intel here...you won't see an Intel chip get near as close to TDP as an AMD chip does under full load.

Oh man , AMD makes one bad CPU and every Intel fanboy shits his pants , AMD is no dead and it won't be , they can still do this ! Win Vista was a FAIL and Win7 is Good and so on ( just to give you an IDEA )... companies make bad and good products , they just have to learn for there mistakes ( Just like MS did whit Win7 - still they won't in the end but Win 9 ... ) . But when you are an FanBoy , you are STUPID and we must get that . So all of YOU STF and let Piledriver come out , then we are gone see !!

I think what most people forget is that Bulldozer is a brand new architecture that is in its pure infancy stages, its not bad. Let's all just forgive and forget that Netburst was terrible at first too. Sure, IPCs aren't what there were expected to be and single thread performance is suffering, but no one is looking at the comparative scale between AMD and Intel. I'm not comparing a Core i7-3960X to a FX-8150, they aren't on the same playing field. Core i7 is over a grand, FX is about 190 bucks for example. Its time to stop comparing apples to oranges. AMD isn't going anywhere, its just switching paths to be able to grow again.
