Took a month to arrive so minus one star. Tempted to chop off another star because I expected to get 10nm by now. But they did well enough with this yet-another-14nm CPU. Let’s all take a moment.
Performs 40% to about 100% faster on all of my workloads than the 4-year old 6-core 22nm i7-5820K it replaced.
I9 consumes only a fraction of the power and less heat at low utilization compared to that old x99 chip.-Peaks at about 176 watts after 12 minutes of running P95 torture test. Temps briefly peak in low 80’s for that dated and unrealistic test. (Motherboard maker monitoring software shows mid 70’s, Intel software shows low 80’s…)
Except for initial setup and testing. I don’t manually overclock the 9900k. Since that would only give me about 3% more performance. Than I get running optimized with no power restrictions enabled. (e.g. out of Intel TDP spec, but the common default for these early Z390 boards). Just disable the throttles and enable auto for the voltage and stuff.
-5.0 GHz for common few core load for long periods, and 4.7 GHz on all cores forever under heavy load (e.g P95) is what I’m seeing with the above config. I’m just using basic H115i PRO AIO cooling and have yet to see any workload force throttling to the official 3.6 GHz speeds.
Times have really changed since my hard core overclocking days 20 years ago. With throttles disabled, the CPU does exactly what I would want to achieve.
It’s organic overclocking virtually out of the box. Turbo boosts to workload optimized fantastic speeds when needed, reduces down to less than 25 watts TPD when not under stress even while still hitting 5.0 Ghz. I don’t have to do any switching or adjustments between workloads. No distractions. Perfect!
Unlike the much more expensive xx99 chipsets, Z390 enables Intel onboard GPU with Quick Sync for better performance and lower CPU utilization/power consumption, which is something I have long missed for some of my workloads, one of which runs 24×7.
Seems to be a great price if you compare to x299 platform prices. Thanks to AMD’s innovation, Intel is cannibalizing its own HEDT segment.
It marketed as a gaming CPU. But IMHO it’s a great choice for workstation needs. There’s a lot of frustration in the 12-year-old-at-heart gaming community with this chip.
It expensive for that market segment especially with prices inflated due to the 14nm shortage, it lacks much innovation over last year’s offering which upsets the frequent must-have-the-latest upgrade’s, and there’s really not that much headroom for overclocking without industrial cooling equipment.
If you have an older (3 years+) CPU and looking to rebuild your system and want to invest in a high performing chip at a comparably reasonable price (compared to x299/HEDT platform and adding in extra cost due to the 14nm supply shortage). I9-9900K is a fine choice that gives you the latest and greatest. It’s a safe bet since Intel’s 10nm performance chips are likely now a 2020 thing.
If you want more value, get AMD’s latest. We all owe AMD’s innovation some gratitude for forcing Intel to offer this 8-core chip in this segment. Long live AMD.
