Although Advanced Micro Devices earlier this year officially confirmed plans to completely get rid of microprocessor branding, the company has quietly decided to introduce chips made using 32nm process technology in FM1 packaging under Athlon II and Sempron trademarks, according to a source with knowledge of AMD’s plans.

With the introduction of A-series accelerated processing units (APUs) AMD also rolled-out new FM3 platform for mainstream offerings. But while AMD’s code-named Llano APUs do offer up to four x86 cores and a desktop-class graphics adapter, not everyone needs integrated graphics solutions and many prefer discrete chips. In order to address those customers, AMD plans to offer “graphics free” Llano chips, a source indicated.

The new central processing units will be made using 32nm process technology and will have similar characteristics similar to Llano APUs (advanced power consumption management, performance tweaks, etc.), but will naturally lack graphics adapter. The novelties will only be compatible with FM1 mainboards.

 AMD intends to offer the “graphics free” Llano processors under Athlon II and Sempron brands. The first model – Athlon II X4 631 (2.60GHz, 100W, 4MB L2 cache) – is already listed on the company’s web-site. Thanks to 1MB of level-two cache, the new Athlon II should provide higher performance than previous-generation offerings with 512KB cache per core in certain cases. 

Since the new Athlon II and Sempron are made using 32nm process technology and are generally inexpensive (the Athlon II X4 631 costs $79 in 1000-unit quantities), they may become popular among overclockers.

Force would be with you AMD!

wow ... the old Athlon II x4 650 were using old 45nm technology and running at 3.2 ghz having a TDP of 95 w and this one is on 32 nm having TDP of 100 watts ... something is seriously wrong here

Yes your conclusion is wrong.

You forget:
a) the TDP does not really equal consumption (as such e.g. take the current i3-2100s or SB-Pentiums) --> they are in a 65w TDP envelope and realistically need maybe half --> the same applies for most undervolting conducted on current APUs (as such again only the "official" TDP is set higher)
b) the TDP could already be 100w "officially" if it needs around 66w --> thus not "officially" in the 65w TDP envelope which could be addressed by over-priced but in-the-end similar CPUs/APUs --> see Intel and their "S" variants or AMDs 45w AM3 versions of CPUs
c) Northbridge integration etc. is as well missing from your deduction (which in itself will add e.g. about 5 watts to the official TDP i.e. 95w TDP (former TDP class) + 5w the original Northbridge TDP = officially 100w TDP --> simply stating the potency the CPU cooler has to have --> overall efficiency is higher due to integration

This list is by no means complete --> however do not jump to conclusions too quickly!

PS: The same would apply to the "Bulldozer to be bundled with watercooling" information that floated around the past few days. Why would a 125w TDP CPU "need" watercooling? If you look at most (unconscious) deductions most comments/forum entries etc. however end up going into that direction of thought. --> Why not assume AMD wants to cater the "extreme" crowd with a (ever so more popular) watercooling?! There will still be normal or tray versions, so what is the problem? It is naturally NOT needed to watercool these CPUs (as in the past with similar TDPs)

I disagree with you. Both TDPs were given by AMD themselves so it is expected that they have tested this similarly compared to its other chips... meaning that the Thermal allowance on this chip is indeed higher than the 95 Watt variant.

No problem, but then i wasn't clear enough:

the TDP allowance is higher (100 vs 95) which however does include the headroom for the GPU portion.
If the GPU portion is disabled it would mean that the real consumption, assuming the GPU is indeed disabled, would go down. No matter what the initial TDP classification was.
In essence, the real consumption of the chip incl. GPU might be 100W but with GPU disabled would only be e.g. 80W. However it would still "officially" receive the label "100W TDP".

This is why I brought in the Intel i3-2100 example. Officially 65W, but in reality it is maybe half. However selling "officially 35w" can be done with a premium (plus TDP is an important information for OEMs).
As such why would I (as AMD or Intel) classify my products "according to reality"? If I can reap additional profits for what is essentially the same chip? (Pentium G620 and Pentium G620T)

And here I was thinking that AMD had done away with what Intel started. "But while AMD’s code-named Llano APUs do offer [...] a desktop-class graphics adapter, not everyone needs integrated graphics solutions and many prefer discrete chips" - isn't that the market segment that Bulldozer is supposed to address? Llano's IGP paired with a Radeon HD 6570/6670 is equivalent to somehthing about as powerful as a Athlon II and Radeon HD 5770, which has balanced performance (yes the IGP still bottlenecks the CPU). Who in their right mind would pair a high-end graphics card with a mid-range CPU? The CPU would bottleneck the graphics card. AMD is starting to become Intel here with their six or seven different brands in the consumer market.

it is just a failed apu whit to much damadged gpu parts so they disabled it. just like the 3cores there also failed 4 cores but whit a good enough gpu to sell it but the bad thing is the unused parts will still consume power.

Sempron what is the point AMD come on the Athlon branding as already taken over the budget market.

well actually the Llano chips perform like phenom chips.
if you look at reviews..and are clocked slower

and the first batch would use more TDP
since its first gen at this size. once they get more efficient
at the process and how to reduce leakage it'll get better

also why do intel chips run so hot ?

intel has a solution with their 3D transistor
we'll see if that helps out or not

they may become popular among overclockers.

Ordinary Athlons have >3.0GHz, 32nm Athlons 2.6GHz only. It's obvious that they are APU w/ GPU disabled and can't be overclocked higher, otherwise they'd had higher freq.
Their appearence is the evidence of the fact of bad SOI fab utilization.

The chips that have defective GPUs must be used so it is normal they are launching such products. If anybody needs such stuff, they'll buy it. If not, they won't.

Besides OEMs traditionally try to fool the client with lower quality and absurd configurations. The average idiot buying a PC will look for "quad core", "1GB video card" and "x GB of RAM" .

So they actually need to use a video card with 1GB of RAM no matter if it it twice slower than an APU.

So why use a good APU and a 1GB video card when you can use a CPU with no GPU inside thus lowering your OEM costs?

On the other hand, it would be nice if AMD would power gate the GPU part and lower the TDP of these new Athlon II chips.
