With eight full cores but no Hyper-Threading, the Core i7-9700K ends up as a net win over the previous generation Core i7-8700K (and i7-8086K by extension).

Stream and record your gameplay without compromising your gaming experience with the new big brother core i7-9700K processor. This is most useful for people that run professional applications like CAD/CAM, ray tracing or path tracing tools (eg, 3D Studio Max, Cinema 4D, Maya), and/or video editing packages (eg, Premiere)—or anything that might result in a similar multithreaded workload, like livestreaming a game and using CPU-based encoding for the video. If you never do anything with video editing or other heavy multithreaded workloads, save the $100-$200 you'd spend on the CPU upgrade and liquid-cooling solution and get the Core i7-9700K—and put any extra money into a better graphics card. Performance has always been a major factor with the Intel CPU’s, thankfully with the release of the new intel 9th gen  i7-9700k that fact remains the same. Thank you for signing up to PC Gamer. No computer system can be absolutely secure. The Core i7-9700K still beats AMD's Ryzen 2700X in most benchmarks, with Cinebench and H.264 encoding still favoring the 2700X. It even boasts a number of improvements compared to the previous generation. With the slowing down of process node advances, 5-10 percent improvements in core performance each generation is the expectation. In the single-core test, however, the Core i7-9700K prevailed by 3.5 percent. - Click here for more details I think part of the problem with the solder TIM is that the overall package height hasn't changed, which means Intel needs a fair amount of solder sitting between the die and the heatspreader. The difficulty is in assessing the value of these application benchmarks. One thing that hasn't changed is the high price, with the 9700K effectively taking over the 8700K's $374 price point. Turbo clock: 4.9GHz In this test, the Core i7-9700K did very well, though no better than the Core i7-8700K. Yeah, that's not super exciting, but then advances in CPU performance are becoming increasingly difficult. And for those that are looking for the best value, particularly with an emphasis on gaming performance, saving $100 and opting for the Core i5-9600K (review coming up shortly) is another viable option. At stock, the 9700K is about one percent slower than the 9900K, and overclocked the difference is splitting hairs. Once you spec out a reasonable system, the $150 price difference between an i7-9700K and a Ryzen 7 2700X will likely amount to less than 10 percent of the overall price. available on our website, please call us on  010 786 0044 or, Open Monday to Friday 9am to 4pm and Saturdays 9am to 12pm, Copyright © 2007 - 2018 - All rights reserved by EVETECH (Pty) Ltd, Intel 9th Gen Core i7-9700K up to 4.90GHz 12MB Cache LGA 1151 95W BX80684I79700K Desktop Processor / Intel UHD Graphics 630 / Intel Optane Memory Support / Enhanced Intel SpeedStep Technology / Intel Virtualization Technology (VT-x) / Intel vPro Technology, (Discounted Price Performance varies depending on system configuration.
