This is a great CPU! Pros: - Overclocks very well as long as youre willing to up the power limit appropriately - Very stable platform, which is the main reason why I purchased this CPU - Its a perfect CPU for gaming and CAD when you need high IPC Cons: - Very power hungry for 8-cores - Can run very hot when the power limit hits a certain threshold - A little pricey at the moment, but worth it depending on what youre using it for - And of course, the big con which is that its a 14nm chip Other Thoughts: Ill be honest, I am very impressed with this CPU. I was very torn whether to go with the Ryzen 5900x, but for my line of work, I really needed a CPU with a high IPC, which this fits the bill. Ive got this overclocked to 5.1GHz on all cores, with it set to turbo boost to 5.3GHz on one core (two threads) and it performs way beyond my expectations. To achieve this, I had to set the power limit to 280W, with the offset voltage maxing out at only 1.360V. Temps reach about 85C max while rendering, using the Noctua NH-D15 CPU cooler. This CPU would easily overclock higher, but 280W is all Im willing to give it, and I wouldnt be able to cool it with my air cooler. Ive paired this with the MSI MPG Z590 Gaming Carbon WiFi Gaming Motherboard & Corsair Vengeance LPX 32GB DDR4 3600 Memory. My previous setup was an 8700k overclocked to 4.9GHz, but was starting to show its age while doing CAD work, so I upgraded. No joke, while rendering a 4K image at maximum quality using Solidworks Photoview 360 with three test images, it completes each rendering in almost exactly half the time! I am so impressed! Also, all my programs are so much snappier, especially Solidworks. I didnt expect this much of a performance boost from my 8700k. I highly recommend this CPU!
