Product description

Product Description

Intel Turbo Boost Max Technology 3.0 identifies the best performing core(s) on a processor and provides increased performance on those cores through increasing frequency as needed by taking advantage of power and thermal headroom. Intel Turbo Boost Technology. Intel Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it, and increased energy efficiency when you don't. Intel Hyper-Threading Technology. Intel Hyper-Threading Technology (Intel HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner. Intel VT-x with Extended Page Tables (EPT). Intel VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory intensive virtualized applications. Extended Page Tables in Intel Virtualization Technology platforms reduces the memory and power overhead costs and increases battery life through hardware optimization of page table management. Enhanced Intel SpeedStep Technology. Enhanced Intel SpeedStep Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.

      Works great. Not much of an upgrade from the Haswell line in terms of performance but definitely runs cooler and that's great. I've got it slightly overclocked to 4GHz and C-states disabled (pro-audio workstation with watercooling) and the average temp is about 38 C. Not too bad.

      Reviewed in the United Kingdom on 17 May 2017
      Style Name: Processor OnlyVerified Purchase
      Compared to the 8 core Ryzen this is the best Intel chip you can get for the same price range. Its 6 cores easily go to 4.2Ghz even if you're not an enthusiast. Runs silent even when it's overclocked to this frequency. Chilling this CPU with the same Corsair H100iv2 as the Haswell 4790K it replaced turns out to be more silent under load at the same speeds.

      The downside is that, for now, the only option for this CPU is the old X99 chipset which is lagging behind with the newest options you get with Z270 chipsets. It's still the loudest bang for the buck in the HEDT playing field if you want the capability of 40 PCIEx lanes.

      Intel gets 4 stars since the chipset is so old that lower, current, offerings inspire features into the next gen X series and it makes a slow evolving chipset part with a high price tag for such a low offering. E.G.: no raid support on M.2 storage even on slot adapters.

      Reviewed in the United Kingdom on 3 March 2017
      Style Name: Processor OnlyVerified Purchase
      I was buying a complete new system and this CPU really was more of a childish want rather than a 'Fit my need' kind of purchase. Yes the new AMD chips at half the price outperform this CPU in many areas and not necessarily at a lower quality compromise but.. it's INTEL and it is Quality.
      I Game And I process video so it does what I need it too but for the cost there are other options. I'm happy with my buy rather than gutted I didn't choose a competitor, I just wish the price bracket wasn't so steep.

      A great buy and a great buy experience.

      Un procesador rápido, con un consumo bastante reducido en reposo, con capacidad de olverclock ya que el reloj no viene bloqueado. Las temperaturas son mas que razonables si le pones un disipador de calidad.

      Es sin duda el mejor micro que puedes comprar sin llegar a los mil y pico euros del 6900K y que este, a diferencia del 6820k tiene 40 lanes PCIe, por lo que con una buena placa puedes tener mas dispositivos funcionando a la velocidad del PCIe 3.0

      Reviewed in India on 31 December 2016
      Style Name: Processor OnlyVerified Purchase
      Best Processor in the world.
      Fastest Core Clocks in above Quad core processors.
      Because of 40 PCIE Express Lanes I purchased this.
      Belive me if you want a processor which must easily last for atleast 5 Years from 2017 definitely buy this.
      Because this is the 3rd Best Processor in the Whole World at consumer afordable price range.
      Ut can be easily overclocked upto 4.4Ghz with a great liquid cooler.
      Great Overall.
      Best for all productivity work.
      Here I have researched.
      1) For company: Xenon/i7 6950X.
      2) For multiple VM handlings buy i76900k
      3) Single PC with Overkilling benchmarks With all gaming and productivity
      Ex. Video Editing and Rendering.
      After Effects and all adobe suits.
      Maya and 3D modelings and all works like deep learning buy this i7 6850K.
      And if you don't want SLI with M.2 and thunderbolt ports buy i7 6800K.
      The i7 6700K is only for gaming and somewhat editing stuffs.
      Ex. If rendering a 4K 10min 60fps footage in primier pro with gtx 1070/1080 the render times will be arround:
      i7 6700K: 22 min
      I7 6800K: 16 min
      I7 6850K: 14 min.
      Other are also like i7 6900k: 13:30
      And i7 6950X: 11:30 min.
      Which of useless to spend so much.
      So this is the best.
      Gaming all above 100 fps in 1080p and above 80fps in 1440p and above 60fps in 4K UHD.
      So Buy it and be relax about all the performances.
