IntelCore i7-9700K Desktop Processor 8 Cores up to 3.6 GHz Turbo unlocked LGA1151 300 Series 95W

so got this about 3 years ago now thought i make a review on it so the i7-9700k is a great cpu i have not had problems with no overheating no problems i have built it a gigabyte z390 designer motherboard got a NZXT Kraken Elite 360mm for cooling and its still going strong i would recommend this cpu for beginners because its a budget friendly cpu.

I had an i7 processor and/or motherboard go bad. It still worked if you set it to a single core, but the multicore stopped working. I had way too much stuff setup on the computer and didn't want to buy a new computer and have to reinstall hundreds of applications and move all the data, so I decide to fix the existing Lenovo Legion computer.Rather than try and figure out if it was the processor or motherboard that went bad I bought a replacement motherboard from Lenovo (only place I could find it) and this i7-9700K.To my knowledge Intel no longer produces the i7-9700K processor and I needed to have this exact one since it was going into a legacy motherboard, so I had to purchase a used processor.The i7-9700K came in a plastic processor package and that was placed inside of a small, padded, mailing envelope. It arrived in great shape, no issues there.I was a little leery of it not working but I pulled out the old motherboard and processor but in the new ones and the computer started up and has been working great.The only problem that I've had, which is not the fault of this processor, is that putting in a new motherboard causes all of the authentication for Microsoft Office applications to fail. Still trying to get that resolved. Really hoping I don't have to uninstall all Office apps and reinstall. My other applications that I've run so far had no issues.The processor arrived quickly and has been running great so I'm happy.

I'm upgrading from a 4790k. If you own something from recent generations, then upgrading may be unnecessary (depending on your disposable income). I know the allure of owning the latest and greatest, of which this is for gaming.Previous build:cpu: 4790K @4.4GHzcooler: Cooler Master GeminII S524 Version 2mobo: MIS Z97 Gaming 7gpu: Asus ROG Strix OC 1080 Timemory: Corsair Vengeance 2 x 8 DDR3 1600MHzpsu: Corsair TX750Current build:cpu: 9700K @5.1GHzcooler: CORSAIR H100i PRO RGBmobo: Asus ROG Strix Z390-Igpu: Asus ROG Strix OC 1080 Timemory: Corsair Vengeance 2 x 16 DDR4 3200MHzpsu: Corsair HX850i9700K v 9900K:For gaming, the 9700K is ~$120-150 cheaper and you only lose a few frames and in some cases gain frames. The question of whether Hyper-threading is right for you is up to your application. Gaming benefits from clock speed over core count once a minimum core count is reached. I think the was Intel's rationale in offering the 9700K. It's a budget 8 core unlocked 9th gen cpu with no Hyper-threading.The 9900K is the obvious superior choice for multi-threaded operations and encoding. If you're looking for a powerful encoding cpu for broadcasting/recording, the 9900K will be a budget buy beating out the entry X-series HEDT chips by at least half the price.If you are looking for a high performance gaming cpu, this should be on your short list. Gaming benchmarks comparing the 9700K v 9900K show negligible differences. I'll leave the AMD debate/comparisons for others.I'll let the benchmarks I've attached speak for themselves, but here is the tldr.I overclocked to 5.1Ghz using XMP I, DDR4 3200MHz. I turned off Speedstep and Speed shift as this brought me more stability when playing games, specifically LoL.Idles at ~40 degrees @1.359-1.368v. Under load ~80 degrees @1.376-1.385v.I have included benchmark screen shots (each paired with the corresponding HWMonitor results) from CineBench, CPU-Z, 3DMark Time Spy Benchmark & Stress tests. I'm extremely happy with the performance of this processor. It runs warm, but an overclocker should be prepared for advanced cooling solutions.

Installed this on a Z390 Gigabyte Aorus Master, under a Corsair h115i with Conductonaut like Tom's Hardware said to do. Out the box it's running 4.9 for 1 core, 4.8 for 2-4 cores, and 4.7 for more than 4 cores. Without tweaking any settings, voltages are in the mid 1.2's. In general gaming use, temps run in the mid-50s with this rig, but the XTU benchmark can push them into the 60s. A few half-hearted attempts at overclocking reveal that this chip, like many of its kind, isn't particularly happy with AVX over 4.7, and some of the cores seem more susceptible to this than others. Still, I couldn't get it over 80 degrees C; platform instability happened first, at 5.1 with an AVX offset of -2. (5.1 at -3 ran at 1.4 with not much other tweaking required). Combined with a couple Samsung NVME drives (512G Evo and 1TB Pro) and some 3200 GHz LED RAM, boot times are superfast (with Fast Boot on) - blink and you miss it.I was able to push a 7680x1440 three-monitor rig to 60 fps minimum in GTA Online; average framerates were in the 90s, though nVidia Surround had me limited to 60 Hz. The same 1080Ti could only do 23 fps minimum with my prior rig, which was Z77/[email protected] GHz based.Nearly any other game I can push my ROG PG279Q to its full framerate of 165 Hz without difficulty. I like to play Rocket League at 250 fps to minimize input lag and was pleasantly surprised to find that I could keep it over 200 and still get what that game calls "quality" graphics on both the single-monitor and triple-monitor setups. I'm old enough that I'll take whatever edge I can get!Install was a snap, watch a video if you're worried about it. Computer booted fine the first time I turned it on - if you can turn a screwdriver you can build a PC. And this processor is the one to get - I expect to be future proof for many years!
