Hi all,
I am thinking of upgrading my laptop in the future, and I wonder if zemax did some benchmark test between Intel core i9-13980HX and AMD Ryzen 7945HX?
https://www.amd.com/en/products/apu/amd-ryzen-9-7945hx
Furthemore, does 32GB ram is enough for both of these CPU?
Thanks,
Nadav

Hi Nadav,
I don’t believe any benchmark tests have been conducted in-house. For a general comparison between the two processors, there are a number of benchmark websites, such as “userbenchmark.com”.
Regarding RAM utilization: 32Gb should be enough for most types of simulations. RAM usage typically ramps up when the system is optimizing a very large number of non-sequential rays through a complex system and/or has imported CAD components. For these cases, 32GB should be OK, but maximizing memory on the machine would be recommended.

Post this to the Reddit optics group. There’s someone there who will be able to answer this.
To the Zemax team: It would be great to get some detailed information on this. The Intel CPU mentioned above has 8 “performance” cores an 16 “efficient”. The AMD just says 16 cores.
Which one is faster? Also, does the answer depend on sequential vs non sequential?
+3I don’t know about Intel’s marketing these days, but I distinguish between ‘real’ cores, which are actually part of the silicon, and hyperthreaded cores, which use a scavenging approach to make unused CPU cycles appear as a separate core. They’re software cores, rather than real. Real is best.
Hi Mark,
Yes but I’m referring to different types of physical cores.

+3Based on that page, my guess is that Performance Cores are what a big number-cruncher like OS would use, while the Efficiency Cores would run smaller tasks like system-level processes. But it would be fun to play with one of these big boys!
