Launched alongside the even more potent Ryzen Threadripper 3970X, the AMD Ryzen Threadripper 3960X may have the same core count as its predecessor. However, it comes with a brand-new architecture that delivers performance gains as well as PCIe 4.0, making it among the best processors in the Threadripper arena. The 3960X delivers dramatically improved single-threaded performance and has successfully reduced its predecessors’ idiosyncrasies that affect their own performance. It may come with a higher price tag and require the TRX40 motherboard – not to mention, a powerful cooler – but it’s certainly worth the fuss if you can maximize its skills to your advantage.
