AMD Introduces Vision A6-3650 and A8-3850 Desktop APUs
AMD announced two of its first Vision A-Series accelerated processing units (APUs) for desktops today. Built in the socket FM1 package, the A6-3650 and A8-3850 are fabricated on the 32 nm HKMG process. Both pack four x86-64 cores, and while the A6 has 320 stream processors in the GPU component, the A8 has 400 of them. Both chips have 4 MB of cache, dual-channel DDR3-1866 MHz IMCs, and PCI-Express 2.0 hubs to drive discrete graphics.
The AMD A8-3850 has its four x86-64 cores clocked at 2.90 GHz, with the Radeon HD 6550D GPU engine clocked at 600 MHz. This chip has a TDP of 100W, it is priced at US $135. The AMD A6-3650 has its CPU component clocked at 2.60 GHz, and Radeon HD 6530D GPU engine clocked at 443 MHz. This chip goes for US $115. With these two, AMD is targeting higher models of Sandy Bridge-based Pentium Dual-Core and Core i3 Sandy Bridge chips. Both will be available in stores by July 3.

The only Llanos which are worth the price will be the A8 and the A4 dual core ones, as the A6 slower clocked CPU and weaker GPU makes no sense for that difference when you can't just change one of them and you need to change both plus overclocking is limited from what i've read so far in the reviews.

2.Athlon 2 has only 2mb cache and is 45nm
3.power of athlon 2 x4 +6570 is more than 100w close to 150w
4. only one fan is needed for this apu -less noise
Where is the L3 cache from the APU?
Does a 6550 exist for desktop?
Nobody talked about consumption.
The prices vary between countries and the 6570 is more powerful with dedicated ram so peformance will be better; same with the athlon, the 645 is almost better than A8.
Have you read any articles about this? If not then search for information. Until the review gets done on TPU look at Anandtech, Tom's Hardware, XBit labs and you will find out what i'm saying.
i looked at anda and : "Radeon HD 6570 and an Athlon II X4 640 for $175 vs. a A8-3850 for $135" and they say the apu is 89% compared to 6570 so the a A8-3850 is a winner
and software that will use this apu better may come in the future
Wife's computer is an Athlon II X2 250 with HD5670. Pushes everything she does (LOTRO, Sims) at 1650x1050 rather well for the price. If these chips were out back when I bought the parts, I would have certainly opted for them.
If you all look at the Guru3Dreview, it shows the A8 chip doing quite well even at 1920x1080p with some older games on the integrated GPU. HOWEVER, they are using DDR3-1866 @ CL7, and memory bandwidth makes a huge difference on Llano APUs when the iGPU is being utilized. Unfortunately, I believe most PCs for sale with Llano will be using DDR3-1333 @ CL9, and won't have nearly the performance shown in the Guru3D review.
1) New better ΙMC . Imc can overclock rams at 1260Mhz Χ2multi (for DDR3) =2520Mhz !!!
2) Better Overclocking than ATHLON II & PHENOM II , Up to 4,3Ghz on air, WITH IGP O/C at 900Mhz core !
3) IGP 6550D & 6530D can work with discrete ΗD6570 & 6670 in HYBRID CROSSFIRE !!!! With little money you can have gaming pc or gaming HDPC ....
4) IGP 6550D is very good overclocker. 900Mhz core
5) FM1 motherboards have NATIVE USB III support, Native SATA III support & lucid virtu support.
6) The total performance from IGP+ CPU is better than Sandy in the same pecuniary cost !
Apus are the best chips for OEMs (Dell, HP, LENOVO) , for HDPC (MEDIA CENTER), for small GAMING DESKTOPs and for all simple users !!!
From what I gather overclocking is a big problem atm however. The baseCLK frequency of 100 drives both the frequency of the core, the NB, the GPU and the memory controller and all the other little controllers like usb and sata. Multiplier overclocking seems to be broken on most motherboards and only the BaseCLK can be overclocked. But if that wasn't enough it seems you can't go over 120MHz because you break usb and sata support.
Edit: Yes the basic was 1333MHz. 1660 offers a ~12-14% gain and 1833 offers ~20%
