The i7 5820K review features a latest enthusiast-level of Intel’s CPU generation, Haswell-E. it is basically a six-core / 12 thread components with 15 MB of shared L3 cache but just 28 PCI Express lanes. It clocks at a slightly slower base clock of 3.3 GHz (Turbo Boost up to 3.65 GHz). The chips of this processer are unlocked.
The good side of this processor is that it is an excellent performer; it features the M.2 as well as the Express support. It also has extra cores for future proofing and has enough PCle lanes for three-card SLI/CrossFire and a PCle 3.0-based SSD.
The other side of Intel Core 5820K review is that it is not compatible with previous generation LGA 2011 motherboards, the stock-clocked performance limited by 3.6 GHz maximum speed and not all software can incorporate eight cores.
The Intel Core i7 5820K is a 5th generation Intel processor that is designed to give you performance need. It features a dedicated 6 x 256KB KB L2 cache, clocking at a base frequency of 3.3 GHz with an acceleration of up to 3.6 GHz because of the presence of the Turbo Boost Technology 2.0. It has the Intel Hyper-Threading Technology that utilises all the available resources efficiently so as to allow the multiple threads to run on every core maximizing the processor throughout.
To stay protected, the Intel Core provides advanced security technologies which include Intel Identity Protection Technology, Intel Data Protection Technology (Intel AES New Instructions) and Execute Disable Bit Technology.
Features and chipset
The Intel Core i7 5820K reviews feature Enhanced Intel SpeedStep Technology. This is an advanced means that enables high performance while meeting the power conservation needs of mobile systems. The conventional Intel SpeedStep Technology is designed to switch both voltage as well as frequency in tandem between high and low levels according to how the processor loads. The Technology builds upon the architecture by means of strategies like separation between voltage and Frequency changes as well as clock partitioning and Recovery.
It is designed with Thermal Monitoring Technologies which essentially protect the processor package and the system from thermal failure with the aid of thermal management features. It is incorporated with an on-die Digital Thermal Sensor (DTS) which detects the temperature of the core while the thermal management features reduce package power consumption and temperature so as to stay in required operating limits.
Overclocking and heat
At Cinebench R15 benchmark, the Intel Core 5820K scored 6% which is lower than that of R5 1600. Ryzen CPU had a better single result as well and they were almost both similar in the overall performance. When overclocked, Intel Core i7 5820K reviewed reached 1305 pts which is the same level with the stock 7800X and 21% behind the 8700K.
For better productivity, the Core 8700K will play a good part with noticeable gains. However, the Skylake-X processors like 7820X or Ryzen 7 CPU is better off. When we look at the Corona results, the Intel Core i7 5820K is in tandem with 7800X when overclocked. It however staggers behind the Ryzen 51600 and almost at the same level with the Stock 8700K while remaining at a slower pace of 24% when we overclock the 8th generation processor.
At stock reviews, the Core i7 5820k is seen to consume slightly more power than that of the 8700K and 12-core/24-thread Threadripper 1920X. It however consumes lesser when compared to 7800X and when overclocked, the chip consumes the same 270W as 5.2GHz 8700K. It gets power hungry at 4.6GHz.
Pricing and availability
The Intel Core i7 5820 price reviews features a reasonable $390 which is the most affordable Haswell-E processor which was available at the time it was incepted in August 2014. The current price on the market is almost half its original which is $200.
The Intel Core i7 5820 is a great processor to maintain if you have if you are a gamer. There is a 6% decline in performance when you use the Core 5820k as opposed to Core 8700K and the margin can be halved when we think of the 4K. An alternative to this processor could be the Ryzen 7 1700 which when combined with B3500 board can support a 4GHz overclock.
