It runs at a base frequency of 3.3GHz, and can be accelerated to 3.6 GHz, thanks to Intel Turbo Boost Technology 2.0. Intel Hyper-Threading Technology uses resources efficiently, enabling multiple threads to run on each core and increasing processor throughput. Now, you can run multi-threaded applications with noticeably fast speed, and perform multiple tasks with astounding responsiveness and smoothness.

general information

Robust Security

Start up your system safely. The Intel Core i7-5820K Haswell-E processor employs advanced security technologies – including Intel Identity Protection Technology, Intel Data Protection Technology (Intel AES New Instructions), and Execute Disable Bit Technology – to ensure maximum security.

general information

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.

Thermal Monitoring Technologies

Thermal Monitoring Technologies protect the processor package and the system from thermal failure through several thermal management features. An on-die Digital Thermal Sensor (DTS) detects the core's temperature, and the thermal management features reduce package power consumption and thereby temperature when required in order to remain within normal operating limits

Intel Virtualization Technology

Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments.

5 out of 5 eggsFantastic CPU

Pros: This cpu was a wonderful step up from my old 3570k.

Runs at 4.4 at 1.175v and 4.5 at 1.200. Unfortunately, there are strange memory issues when I exceed 4.5GHz, even though I can maintain a high clock speed with relatively low voltage.

Load temperature are within 70-75 using Aida64 and a H110i GTX. Gaming load doesn't exceed 50 degrees.

Much better than my 3570k, which could only do 4.2 at 1.325.

Cons: None really, as they aren't relative to the CPU.

Other Thoughts: The cpu is fantastic. I can't say the same for the motherboard and ram that I bought with it.

The RAM constantly blue screens the computer in XMP mode, so I have to manually neuter it's speed down to 2100MHz to even get to Windows (rated speed is supposedly 3200MHz) and two EVGA x99 Micro 2's have died on me.

The CPU ran beautifully through all of that. I have a third x99 Micro 2 on the way, hopefully this one won't be a dud.

It's a shame, cause it really feels like this one can overclock a lot higher than the memory and motherboard will allow.

It does 4.5 at 1.2v dead stable for 24 hours of Prime95 26.6 and 12 hours of Aida64 without breaking a sweat. 70-75c in stress tests, 50 in games.

Imagine what it could do with 1.3-1.350 volts

5 out of 5 eggsGood

Pros: what can I say, its a processor that does what it says? Easy overclock. Just tried 4.5 and 1.3 volts, and was totally stable. Don't think I'll need any higher than that.

Cons: none

5 out of 5 eggsBest Bang for your Buck

Pros: - Best Price Point per Passmark Score

Cons: - None

Other Thoughts: This CPU can fly. Built two servers with this CPU and both are functioning amazingly under high load and utilization. Use a motherboard that supports server drivers if this is your intention. I used the Asrock x99 WS

5 out of 5 eggs4.8ghz...

Pros: 3rd best price to performance ratio of all cpu's, absolute best among intel cpu's.
overclocks like a monster... I got mine to 4.8 ghz, but stress tests maxed it at 85 so i dropped it down to 4.6 and 80c max now under aida64.
under a noctua nh15 it peaks at 65c underl full load outside of stress tests.
The chip i got does 4.6 @ 1.280 volts and 4.8 at 1.320.
Passmark score of 18.4 to 18.6 at 4.8, 17.8k @ 4.6.

Cons: Expensive platform to get into, But well worth the price.
Not many decent 2011v3 motherboards out there, so its basically either asus or asrock, you can forget the rest, too many defects...
overclocking options are a bit overwhelming at first, but google is your friend in that respect.

Other Thoughts: Upgrading from an 8320 @4.5 this is just insane, nearly doubled my passmark score :D now i rank as one of the highest 5820k passmark scores on the site :) Also... i can stream bf4 @720p60fps and still max bf4 out at a near constant 200 fps :)

5 out of 5 eggsA Multitasking Machine!

Pros: -Can easily handle heavy workloads (Downloads, multiple open programs, and watching videos at the same time!)
-Is a great price compared to other X99 chipsets
-Great for video editing

Cons: -Only has 28 PCI Lanes which makes SLI not as beneficial
-Generates a descent amount of power, but not too much

Other Thoughts: - I would recommend this to people who do video editing and a lot of multitasking often.
- I game on it often and its great, but there are cheaper processors out on the market that can get the job done just as well for a lot less money.

5 out of 5 eggsA great CPU for CPU-intensive workloads.

Pros: • This CPU is very fast. Transitioning from an FX-6300, I was expecting a lot, and it still surpassed my expectations. A 25-minute encode inside of Adobe Media Encoder on my FX-6300 (overclocked to 4.5ghz) would take around 7 minutes on this chip.

• In terms of gaming performance, it performs about 85-100% as efficiently as an i7-6700k on Skylake. There will be games where this chip falters, specifically titles with poor multi-core support, but never enough to lessen your gaming experience. It also costs about the same, if not cheaper in some cases.

• The decision to not include a stock cooler was nice, as this is a very hot chip, and will likely demand an aftermarket cooler if you wish to use it to its fullest potential.

Cons: • This chip, like other Haswell and Haswell-E chips, is very hot. Overclocked to 4.3ghz at 1.225v, this chip will idle in the low 40s, and slowly creep upward toward the mid-high 40s the longer my PC is running. Under an artificial load (AIDA64) I saw temperatures as high as 85c. This is stable however. Just note that this chip is very hot.

• The X99 platform is likely to come to an end soon, which means aside from the 5960X, there is no longer an upgrade path for the 2011-v3 socket.

Other Thoughts: Overall, I am very impressed with this chip, I knew what I was getting myself into by buying into such a high-end platform, but it still took me by surprise, just how fast it is. On an NZXT Kraken x61, it still runs very hot, but never unstable. The socket may be at its end, but the chip itself should definitely be good for many years to come.

5 out of 5 eggsIdle CPU usage of 1-2%

Pros: -Great for multi tasking, Asus has a great overclocking program that individually overclock the cores to conserve power and reduce heat.
-Overclocks Like a Champ

Cons: -Power Consumption, If you are going to us a highend GPU such as the 980ti, play it safe and get at least a 1000w Powersupply. This is because the CPU alone draws a ton of power, then to add 2-8 pin PCI-E connectors to the GPU.
-Also, some houses are not equipped with proper power output and if you overclock, it would be safe to add some more power to the room.

5 out of 5 eggsLove it

Pros: This CPU is blazing fast, overclocked to 4.3ghz via Asus' overclocking tool, I can likely go much higher once I do it manually and replace the current RAM and replace with better MOBO. I love hyper-threading as well.

Cons: Price

Other Thoughts: I'm coming from a 2500k and do a lot of gaming, and I constantly read people saying how there is no point in upgrading from a 2500k yet. I strongly disagree. My minimum and average FPS in my favorite game has shot up by a whopping 15fps.
On top of that, even if people mainly use their PC for gaming, I imagine everyone also uses their PC for other tasks which could include programming, photoshop type work, etc. and this is a great processor for many reasons besides games.

You really can't go wrong with this.
