Intel recently released a pair of rather odd high-end processors: the 14-core Core i9 9990XE and the 28-core Xeon W-3175X. Both have higher clock speeds than other models with similar core count, run much hotter, and have other peculiarities. Because of that, neither of these processors will have a home in our product line at this time – but they are still interesting to test for insight into what current CPU designs are capable of when pushed beyond what is practical.
Dynamic Local Mode is a new feature on AMD’s biggest Threadripper processors. These CPUs have cores grouped internally, some with direct access to system memory and some which have to communicate through those other cores to access data in memory. DLM prioritizes running code on the cores which have a direct line to the memory, helping to improve performance in situations where not all of the cores are in use. How does that translate to real-world workloads, though? Let’s take a look at two CPU-based rendering applications and see how the 24-core 2970WX behaves with this feature on and off.
