6-core/12-thread Core i7 for $200, i7-5820Ok Revisited


Released in August 2014 for an inexpensive $390 — essentially the most inexpensive Haswell-E processor to be had on the time — Intel’s hexa-core Core i7-5820Ok has confirmed standard amongst fanatic developers over time and it is about time we see the way it compares towards extra trendy CPUs.

Today, the chip will also be bought for almost part the cost it in the beginning fetched and we controlled to search out one on-line for round $200, which appears to be in regards to the going value.

By default, the 5820Ok works at a base frequency of 3.3GHz however relying at the workload it could possibly spice up as much as 3.6GHz (a light building up, admittedly) and it additionally packs 15MB of L3 cache along 1.5MB of L2 cache, which used to be a vital building up over the mainstream Core i7 vary again in 2014.

Although the chip is pin-compatible with the previous-generation Ivy Bridge-E and Sandy Bridge-E forums, we determined to put in it on an upgraded LGA2011v3 setup. The socket exchange used to be slightly justified this time seeing as Haswell-E noticed the adoption of DDR4 reminiscence on Intel’s high-end desktop platform. As used to be the case with preceding generations, quad-channel reminiscence make stronger remained and the reputable spec known as for DDR4-2133.

Since the discharge of the 5820Ok, we noticed the 6800Ok jack this class’s value as much as smartly over $400 after which ultimate yr the 7800X went back off to $390. Of route, 2017 additionally introduced the Ryzen 5 1600 for $200 and the 8 core/16 thread R7 1700 which will also be had for $290. Intel’s high-end desktop platform if truth be told confronted some actual festival in 2017, one thing it is by no means truly observed.

Our center of attention shall be on gaming for this retest and the purpose is to perform two issues: 1) to turn the ones of you presently the use of a 5820Ok what benefits there is also to upgrading, and 2) to offer second-hand customers with data on whether or not the 5820Ok and an accompanying X99 motherboard are price snapping up — $200 for the 5820Ok plus $80-$100 for a supporting motherboard seems like a super worth on paper.

What we will be able to say in advance is that if you are most commonly gaming at the 5820Ok presently, it is most likely now not price leaping send for the 8700Ok and it makes extra sense to attend given what we noticed from our contemporary retest of the Haswell-based 4770Ok.

Clock for clock, at 4.8GHz the 4770Ok used to be simply 15% slower at 1080p the use of medium high quality settings with a GeForce GTX 1080 Ti. On most high quality, that margin used to be decreased to only 10% which fell additional to 4% when expanding the GPU workload to 1440p.

Although we do not look forward to finding a lot distinction with the 5820Ok, you guys nonetheless love benchmark effects and so can we, so we may not let that little reality prevent us. For trying out, we paired the 5820Ok with quad-channel DDR4-2666 reminiscence and that is the reason the absolute best reminiscence velocity our processor would paintings with, no less than with the sticks we have now to be had. The 4770Ok used to be examined with DDR3-2400 reminiscence and the 8700Ok with DDR4-3200 reminiscence.

Before we get to the gaming effects, we have now some Cinebench R15 ratings together with some Corona benchmarks and gear intake figures.


First up, a handy guide a rough have a look at everybody’s favourite rendering benchmark, Cinebench R15. Here the inventory 5820Ok scored 6% less than that of the R5 1600 and the Ryzen CPU posted a greater unmarried thread outcome as smartly. Overall regardless that, they were not significantly other. Once overclocked, the 5820Ok hit 1305 pts and that positioned it on par with the inventory 7800X and a whopping 21% in the back of the overclocked 8700Ok.

If you might be short of to extend productiveness, the 8700Ok will be offering noticeable positive aspects, regardless that you might be at an advantage with a Skylake-X processor such because the 7820X or in all probability a Ryzen 7 CPU.

Here’s a have a look at the Corona effects and we see that the 5820Ok is once more most effective in a position to check the 7800X as soon as overclocked, even though on this take a look at it does pull smartly forward of the Ryzen 5 1600 and nearly catches the R7 1700. Still, even overclocked the 5820Ok used to be 10% slower than the inventory 8700Ok and 24% slower as soon as the eighth gen processor is overclocked.

Lastly, ahead of leaping into the gaming effects here is a fast have a look at energy intake. At inventory, the 5820Ok consumes fairly extra energy than the 8700Ok and 12-core/24-thread Threadripper 1920X, however not up to the 7800X. Once overclocked, the growing older chip ate up the similar 270 watts because the 5.2GHz 8700Ok, so not anything too excessive however at 4.6GHz the 5820Ok begins to get somewhat energy hungry.
