Lenovo and AMD Launch Threadripper Pro CPU To Take on Intel Xeon

AMD finally brings a workstation-class -- in other words, security-conscious -- processor to challenge the Intel Xeon on the desktop with its Ryzen Threadripper Pro. With up to 64 cores, the pro version of AMD's multicore powerhouse Threadripper processors incorporates essentials like support for massive amounts of memory and board-level security, critical for uses which move a ton of sensitive data, ranging from aerospace visualization to Hollywood video editing and CGI rendering. The CPU debuts in Lenovo's ThinkStation P620; Lenovo has a limited exclusive on the processor. From a report: The CPU comes in four variants: 3945WX (12 cores, with the fastest single-core speeds), 3955WX (16 cores), 3975WX (32 cores) and 3995WX (64 cores). At the moment, to achieve core counts that high with the Intel Xeon, you have to use multiple CPUs. They all come with some of the perks of AMD's architecture, including support for PCI Gen4 -- in this case, up to 128 lanes. And the Pro versions add support for more types of memory, notably RDIMM and LRDIMM, over the high-end consumer-focused Threadripper, plus 8 memory channels vs. 4, which lets it support up to 2TB of memory. On the downside, while AMD supports faster internal transfers than Intel via PCI 4, it doesn't offer any high-speed external data transfer capabilities a la Thunderbolt 3. And in fact, the ThinkStation P620's fastest connections are USB 3.2 Gen 2 and 10Gb Ethernet.
