The CPU itself is INCREDIBLY slow and awful to run pretty much anything with. However, it does have one thing definitely going for it.
Despite me having used it pretty much 24/7 for the past 7 years, and the SFF Optiplex 760 it's on, having only been cleaned 3-4 times in its' whole life, because I didn't know how to clean a PC until fairly recently.
Yet the E5300 STILL runs after all these years, and only begun getting any noticeably slower in the past year or so. This kind of reliability is far more than what I can say for Intel's high end CPUs from just the past year. Because half a year ago I finally managed to get a new computer to replace my Optiplex. And so far I've somehow lost TWO CPUs in a row. First the original i5-11400f I had bought, and then the i5-11500 I bought as a replacement. [Feb '225555]
The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18CPUPro]
