• 32 nm 
• 8MB L3 Cache
• 2 x 2MB L2 Cache

• Unlocked AMD FX 4-Core Processor The native 4-core desktop processor delivers unmatched multitasking and pure core performance with all-new “Bulldozer” architecture. New 32 nanometer die shrink was designed to reduce leakage for improved efficiency, increased clock rate headroom and better thermals. Watch rich, crisp HD video. Run multiple compute-intensive applications seamlessly.
• AMD Turbo CORE Technology The AMD FX Processors come equipped with AMD Turbo CORE Technology, a performance boosting technology that helps increase performance on the applications that need it the most.
• New Instruction Capabilities – AVX, FMA4 and XOP, AES Advanced Vector Extensions (AVX) increase parallelism tailored for scientific and 3D applications that use heavy floating point calculations. Floating Point Vector Multiply-Accumulate improves throughput and performance on many vector functions (integer and floating point). Advanced Encryption Standard noticeably increases performance on the latest encryption applications like TrueCrypt and benchmarks like PCMark.
• AMD HyperTransport Technology HyperTransport Technology (HT or HTT) is a high-speed, low latency, point-to-point link which helps reduce the number of buses in a system thus reducing system bottlenecks and enabling today's faster microprocessors to use system memory more efficiently in high-end multiprocessor systems. With HTT, the AMD FX-4100 enjoys up to 37GB/s total delivered processor-to-system bandwidth (HyperTransport bus + memory bus).
• Integrated DRAM Controller with AMD Memory Optimizer Technology The AMD FX Processor features a high-bandwidth, low-latency integrated memory controller that supports up to DDR3-1866 and new low voltage memories of 1.35V and 1.2V and provides new Pre-Fetcher improvements and direct communications to each core in Dual-Core module (APIC registers in each core).
• AMD Virtualization (AMD-V) Technology with IOMMU Silicon feature-set enhancements designed to improve the performance, reliability, and security of existing and future virtualization environments by allowing virtualized applications with direct and rapid access to their allocated memory. IOMMU is an extension to AMD64 architecture to support address translation and access protection on DMA transfers. AMD-V with IOMMU helps virtualization software to run more securely and efficiently enabling a better experience when dealing with virtual systems.
