New microarchitecture, new level of performance

Piledriver microarchitecture, a tuned-up Bulldozer, has finally reached the flagship AMD FX processors (the new FX series processors are codenamed Vishera) for improved performance and better energy-efficiency. Four “Piledriver” cores ensure rich, crisp video and seamless multitasking. The AMD Turbo Core technology pushes your core frequencies to the most when you need it most. To top it off, like all other AMD’s Black Edition processors, the new AMD FX 4-core Vishera processor is fully unlocked for fabulous overclocking* capability. Great performance is not the only trick AMD has up their sleeve. Vishera processors are at a reasonable price point.

* AMD’s product warranty does not cover damage caused by overclocking even when overclocking is enabled via AMD Overdrive software.

General information

The Control You Want

  • Unlocked clock multiplier for a powerful overclocking advantage (AMD’s product warranty does not cover damages caused by overclocking, even when overclocking is enabled via AMD hardware)
  • Highly configurable power and performance curve via AMD OverDrive software
  • Tailor your experience to your personal preference, whether it’s performance, efficiency, or low noise
General information

Reliability You Deserve

  • AMD processors power premium products and world-class operations from industry leaders like HP, Microsoft, Samsung Electronics, and Sony
  • The AMD FX processor is built from the company’s 8th generation x86 CPU architecture based on over 40 years of silicon-crafting experience

New Instruction Capabilities

  • AVX - Advanced Vector Extensions increase parallelism for scientific and 3D apps using heavy floating point calculations
  • FMA4 and XOP – Floating-Point Vector Multiply-Accumulate and eXtended Operations improve throughput and performance on many integer and floating point vector functions
  • AES - Advanced Encryption Standard increases performance on encryption apps like TrueCrypt and PCMark

AMD Turbo Core Technology

AMD FX Processors come equipped with AMD Turbo Core Technology. AMD Turbo Core Technology is a performance boosting technology that helps increase performance on the applications that need it the most.

AMD Balanced Smart Cache

  • Shared L3 cache (up to 8MB)
  • Improved scheduling and pre-fetch capabilities
  • 64-ways (16-ways/sub-cache)
  • Increased data queue sizes
  • Coherency for multi-cores

AMD Wide Floating Point Accelerator

  • Shared FP Scheduler
  • Dual 128-bit Floating point engines – capable of teaming together for 256-bit AVX instructions or operating separately with each core

HyperTransport Technology

Provides quick access times to system I/O for better performance.

  • One 16-bit link at up to 5600MT/s
  • Up to 8.0GB/s HyperTransport I/O bandwidth; Up to 16GB/s in HyperTransport Generation 3.0 mode
  • Up to 37GB/s total delivered processor-to-system bandwidth (HyperTransport bus + memory bus)

Integrated DRAM Controller with AMD Memory Optimizer Technology

An optimized, high-bandwidth, low-latency integrated memory controller to feed more cores.

  • Supports up to DDR3-1866
  • Supports low voltage memories of 1.35V and 1.2V
  • Up to 29.9GB/s memory bandwidth for DDR3
  • Pre-Fetcher improvements
  • Direct communications to each core in Dual-Core module (APIC registers in each core)

AMD Virtualization (AMD-V) Technology with IOMMU

These silicon feature-set enhancements are designed to improve the performance, reliability and security of existing and future virtualization environments by allowing virtualized applications 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. Together, virtualization software runs more securely and efficiently enabling a better experience when dealing with virtual systems.

  • Security for User Level application and Virtual Machine guest operating system
  • Address translation and access control
  • Device isolation
  • Device assignment in virtualized systems
  • Security and trusted boot support
  • Unified interrupt management

AMD PowerNow! AMD Technology (Cool'n'Quiet Technology)

Enhanced power management features automatically and instantaneously adjust performance states and features based on processor performance requirements, helping users get more efficient performance by dynamically activating or turning off parts of the processor.

  • C6 power state flushes the cache and removes voltage from individual cores to help reduce power consumption
  • CC6 power state puts all cores in C6 into an even lower power state for quieter operation and reduced power requirements
  • Separate memory controller power control
  • IO-based c-state interface
  • Works automatically without the need for drivers or BIOS enablement.
  • Power can be switched on or off within a single clock cycle, saving energy with minimal impact on performance

Benefit: Helps users get more efficient performance by dynamically activating or turning off parts of the processor.

BUY THIS CPU 2/12/2020 3:59:51 PM

- Great low-mid range choice even today

Cons: - It gets hot

Overall Review: Good stuff, it's served me well for a long time, and I don't see any issues coming up soon.

Updated my old Cpu 2/6/2020 7:15:27 AM

Pros: Fair performance

Cons: Runs hot and not efficient. Price for a used CPU is not great, but I had other parts to use with it.

Overall Review: The prices on these are too expensive and actually cost more than when it was first released. If you can, get a more efficient cpu.

Bought this in 2014 and it has held up to the test of time admirably 1/27/2020 7:29:41 AM

Pros: I can still play most newish games at decent settings in 2020 with a GTX 770 at 1080p. You will for sure get some throttling with more intensive games, but that goes for pretty much any CPU from this era. It's also held up much better for multi-tasking and applications that take advantage of more than 2 two cores (even though it's debatable whether this is a 'true' 6-core). The same can't be said for all of Intel's duo cores from this same time period.

Cons: The only recommendation I would make for buying this is if you can only afford to upgrade an older AM3+ platform motherboard with this if you're running something much slower.

Overall Review: I love this CPU and it was a great investment years ago, but it's not the best use of your money in 2020. I would definitely not recommend it for a new build. If you're looking at this for a new build, I would advise you to look at the Ryzen 1600 AF (12nm Zen+ refresh) instead on a B450 board if you are on a tight budget. Don't build a computer in 2020 with a cpu released about 8 years ago. The FX-6300 is nearing the end of it's usability.

New engine for an old computer 1/10/2020 11:11:52 AM

Pros: Pull out the old processor plug in the new one.
The speed difference is amazing

Cons: None

Overall Review: When my wife got a new computer, I moved her old one out into my workshop. I find that many repair or assembly problems were previously solved by someone else and posted on line. The old Acer Aspire M3400 was just fine for that kind of use. Sadly, I could take a nap while it booted up. I replaced the FX4100 that came in it with this inexpensive used FX6300. Since the FX6300 is supported by the bios, it was a direct swap. I am truly surprised by the performance difference.
