DDR4 Memory Scaling & DDR4-3600 Testing With AMD Threadripper On Linux

The 7-Zip compression results show just how quad channel memory is definitely a noticeable difference compared to dual channel memory when running with AMD Threadripper, similar to our past tests.

The timed compilation of the Linux kernel has a noticeable difference going from two to four memory channels while the memory frequency was less of a difference for this GCC compilation process, although going from DDR4-2133 to DDR4-3600 still yielded a two second drop in the build time.

With the longer process of compiling the LLVM compiler stack, the memory speed and configuration made a much more noticeable difference. Going from two sticks of DDR4-3200 to four sticks of DDR4-3200 yielded an over two minute drop in the build time of LLVM. Using the 8GB DIMMs instead of the 4GB DIMMs for having 16GB vs. 32GB total memory also was of a noticeable difference in this big compilation task. Likewise, the memory frequency made quite a difference here too.
