Intel Core i7-3820 Sandy Bridge-E 3.6GHz (3.8GHz Turbo Boost) LGA 2011 Quad-Core Desktop Processor BX80619i73820

  • Summary: The attractive sub-$300 price tag of the i7-3820 helps fill the void between extreme speed and price of the i7-3960X and still relatively high-priced i7-3930K.  The scarcity and inconsistent pricing of the i7-3930K along with the insanely priced i7-3960X sent many potential adopters into a hold pattern, awaiting a more budget friendly unit for the LGA2011 platform.  This i7-3820 model fits the bill.

Intel Core i7 3820 / X79 Platform - How much Memory is Ideal?

30 March 2012
  • Summary: While setting up Gigabyte's latest Intel X79 motherboard on the PCSTATS test bench a few week ago, we found ourselves wondering; "what's the ideal amount of memory to use in a Intel Core i7 3820 'Sandy Bridge-E' platform these days?" Obviously, with a 32-bit Windows 7 OS we'd be limited to 4GB of system memory, but what's the magic number for Windows 7 64-bit?

  • Conclusion: The Intel Core i7-3820 processor is a fine performer, but it lacks the impressive features of other CPUs in the Sandy Bridge?Extreme line.
  • Pros: Very good performance, particularly on single-threaded applications.
  • Cons: Inconsistent compared with other high-end Intel chips. Partially unlocked multiplier limits overclocking potential. Requires X79 Express motherboard, video card, cooler.

Intel Core i7-3820 Extreme Edition CPU

Benchmark Reviews
11 March 2012
  • Conclusion: As we have explained in the past, it's very hard to isolate a single component within a system. While we try to keep as many of the components static throughout the testing environment, it's impossible to keep everything the same. Any of these other components can cause fluctuations in the performances shown by the benchmarks. With that in mind, the i7-3820 performed pretty much just where it should have in our tests.

Intel Core i7-3820 Quad-Core Core Processor Review

8 March 2012
  • Summary: Final Thoughts When the LGA2011 processors and Intel X79 motherboards were released it was quite expensive to get into.  The Core i7-3930K sells for about $600 and you will be paying over $200 for an Intel X79 motherboard.  This does not leave much room for a decent video card, memory or solid state drives.  The Core i7-3820 comes in at just over $300, about half the price of the i7-3930K.
  • Pros: Price, PCIExpress 3.0 with 40 lanes, QuadChannel DDR3, 10MB Cache, Easy overclocking because of the Gear Ratio feature
  • Cons: Not a fully unlocked processor, You lose Intel’s QuickSync technology if moving from LGA1155

Intel Sandy Bridge-E i7-3820 CPU Review

  • Summary: Who said all good things come in 3 fold ? Today we introduce Intel's youngest offering in the SnB-e lineup. The i7-3820 is not a hexacore like it's two bigger brothers ; the 3930K and 3960X. But a Quadcore version for the socket 2011 platform. This allows Intel to launch it at a far more affordable price then the two previous mentioned socket 2011 models. Thus making the i7-3820 maybe a perfect replacement CPU for the socket 1366 Bloomfield CPU's.

Intel Core i7-3820 Sandy Bridge-E Processor Review

Hi Tech Legion
19 February 2012
  • Summary: The Intel Core i7 3820’s performance tiered well with the other Extreme processor. As an entry X79 processor, the performance was better than the high end 2600K. I have always been a system upgrader. This meant that I take part prices into consideration more than a "total" system price. I usually transfer old parts over to the new system as they are still up to date.
  • Pros: Quad Core with Hyperthreading, 10MB Intel Smart Cache, Turbo Boost 2.0, AES instructions and Disable Security Bit functions, AVX Vector Extensions, 40 lanes of PCI Express 3.0, Intel Enhanced Speedstep Technology, Intel Extreme Memory Profile 1.3 (XMP), Quad-channel DDR3 support, Price
  • Cons: Feature Tradeoff with 2600K Processor

Intel Core i7-3820 Processor Review

9 February 2012
  • Conclusion: To be fair, the i7-3960X isn't all that impressive when gaming either, though it's at least on par with the 2600K. I believe the SB-E parts struggle here because they have inferior memory performance to the 2500K and 2600K. Despite the newer chips supporting quad-channel RAM, the SB-E processors have a higher memory latency, which attributes for the loss in bandwidth.
