Released in August 2014 for a reasonable $390 -- the most affordable Haswell-E processor available at the time -- Intel's hexa-core Core i7-5820K has proven popular among enthusiast builders over the years and it's about time we see how it compares against more modern CPUs.

Today, the chip can be purchased for nearly half the price it originally fetched and we managed to find one online for around $200, which seems to be about the going price.

By default, the 5820K works at a base frequency of 3.3GHz but depending on the workload it can boost up to 3.6GHz (a mild increase, admittedly) and it also packs 15MB of L3 cache alongside 1.5MB of L2 cache, which was a significant increase over the mainstream Core i7 range back in 2014.
