FX-Series model numbers are less confusing than AMD A-Series, that is it's easy to figure out the number of cores based on the model number. AMD FX-41xx line consists of quad-core processors, FX-61xx line is comprised of 6-core CPUs, and FX-81xx subfamily has processors with 8 cores. Each Bulldozer core has dedicated 1 MB L2 cache, and all SKUs from FX-Series have 8 MB L3 cache. The FX microprocessors are clocked from 2.8 GHz for FX-8100, and up to 3.6 GHz for FX-4100 and FX-8150. Preliminary reports indicated that all parts will have Turbo Core technology incorporated, and turbo frequency on many models will be close to, or exceed 4 GHz. Also, all processors will come with unlocked core frequency multiplier. The microprocessors will work in socket AM3+ and some socket AM3 boards, and will be incompatible with socket AM2 and AM+ motherboards. Please see the table below for a summary of CPU features:
| Model | Cores | Frequency | Turbo Frequency | L2 cache | L3 cache | TDP |
|---|---|---|---|---|---|---|
| FX-Series FX-4100 | 4 | 3.6 GHz | 3.8 GHz | 4 MB | 8 MB | 95 Watt |
| FX-Series FX-6100 | 6 | 3.3 GHz | 3.9 GHz | 6 MB | 8 MB | 95 Watt |
| FX-Series FX-8100 | 8 | 2.8 GHz | 3.7 GHz | 8 MB | 8 MB | 95 Watt |
| FX-Series FX-8120 | 8 | 3.3 GHz | 4 GHz | 8 MB | 8 MB | 95 / 125 |
| FX-Series FX-8150 | 8 | 3.6 GHz | 4.2 GHz | 8 MB | 8 MB | 125 Watt |
Prices for FX chips are not known at this time, although it was rumored that the flagship FX-8150 model will cost around $300. The FX-Series chips are expected to launch on September 19, and it may take a few weeks for the CPUs to appear in retail stores.

nm process
I thought Bulldozer was 28nm and not 32?o.O
There were rumors that 28nm process will be used for the successor of Bulldozer core in 2013. AMD roadmaps show 32nm process for Bulldozer 2011 and 2012 years.
