AMD’s high-performance Zel Zen 3 continues. These chips are the 3rd or 4th iteration of their modern desktop .p processors (or 5th, depending on who counts), and they deliver impressive levels of performance. In this episode of Upscale, we look at what has changed in Zen 3, and how important CPU power really is for functions like animation and video editing.
With the Zen 2, AMDA introduced the idea of a “chiplet”: small discrete processors die that were connected together to form the final chip. The Zen2 CPU used an “I / O die” chip to handle data transfer with one or two “CCD” chiplets with 8 processor cores. In Zen 2, this “CCD” or “Core Complex dies” is preceded by “Core Complex” – CCX that connects 4 processor cores together. Without modifying the architecture of this modular system, let the Ryan 3 3100 scale from 4 cores to 2 scale to 64 core 3990X.
But the design was not without compromise. Each 4-core CCX shared some cache memory, and while data transfer between cores in CCX was faster, the bits between CCX were delayed and the system could slow down. In the Zen 3, AMDA has essentially merged CCX and CCD, chips grouped into 8-core clusters, sharing a huge 32MB of L3 cache memory. This, along with a host of other minor improvements, will help keep data flowing through the CPU without hiccups or interruptions.
Our testing suggests that the flagship 16-core 5950X delivers the fastest single and multicore scores we’ve seen in Cinebench (outside of workstation-grade chips). Effectively, it does so without any big jumps in power consumption. However, our tests have also shown that in most media applications, there is a declining return for higher CPU power. A few apps will scale all the way to 16 cores, and in many cases, including Adobe and Devinci Resol, a powerful GPU can make a big difference these days. If you’re looking to build the most powerful system you can, the 59 799 5950X is definitely a chip to consider, but if you’re on a budget, your money could be better spent elsewhere.
