Intel Core i7-3820 Review

  • 4.5 / 5
    • The good:
      Very good performance, Fine performer
    • The bad:
      Inconsistent, No improvement over 2700K

    Intel Core i7-3820 is a bit within the reach that doesn’t cost the same amount as some full PCs. It is an octo-core server chips with a couple of cores disabled to fit into the desktop segment.

     

    This processor has a partially locked multiplier which limits it to 43x compared to the 57x multiplier offered by both the other Sandy Bridge-E chips and the top-end-K –series i7 and i5 CPUs of the plain Sandy Bridge range. It is not just bust eight-core chip. This time it is with half its goodness turned off that gives a 1.27 billion in its make-up. That means it is still bigger than the previous generations’ Gulftown hex-core CPUs, the entire Sandy Bridge line up and even AMD’s chunky-module Bulldozer chips.

     

    In single-threaded applications, the straight Sandy Bridge architecture has the edge in our test, showing why the gaming performance is higher as well. The overclocking performance of the i7 3820 is quite interesting. Despite being only partially unlocked, meaning you hit the 4.3 GHz limit straight away, you can push it further given the right motherboard. With a decent motherboard you should be able to get up the same sort of overclocking performance around 4.7GHz – as the i7 2700K.

     

    That means the partially locked multiplier really doesn’t impact too much on the overclocking prowess of this new Sandy Bridge chip. But the reliance on a decent motherboard is one thing that goes against the i7 3820, especially fight between it and the 2700K. So the Intel Core i7 3820 performs around the same sort of levels as the top-end standard Sandy Bridge CPUs. On core-for-core performance, you’re not getting much extra for your Sandy Bridge-E money. There are the extra PCle lanes which are useful if you’re rocking more than two graphics cards and the extra bandwidth offered by the new PCle 3.0 tech, but the real value of that is still rather ephemeral at best. There’s only one PCle 3.0 graphics card out at the moment and the benefits that interface alone giving you are limited. The extra memory bandwidth is only useful for a tiny minority.

     

    A number of gamers can already get enough all-round performance out of a standard Sandy Bridge set-up. Some critics expressed their hope for a more impressive, compelling outing for the quad-core version of Sandy Bridge-E. Most of them reassured that the low price of the Intel Core i7 3820 is pleasing, though, and it means that if they want to build the basis for an excellent workstation they can pick up a decently-priced CPU and then splash the serious cash on a hex-core CPU if they can afford or need the extra cores on a later date.

     

    Most users tested that this Intel Core i7-3820 is the cheapest Sandy Bridge-E processor. They liked the fact that Intel has put the chip out for the same price as the top-end Sandy Bridge 2700 is impressive and thoroughly welcome.
