AMD Ryzen 3 3300X & 3100 CPU Review

Sandra Memory Bandwidth

AIDA64 Memory Performance

Memory bandwidth falls in line with what we see from other Zen 2-based chips. As these are single-CCD processors, you get the same half-speed write bandwidth that we see on Zen 2 Ryzen 3000 chips below the twelve-core 3900X.

Memory latency also positions roughly where we would expect it to be. The Ryzen 3 3300X looks to have a little less memory latency and this could potentially be attributed to its single-CCX design.

Speaking of single-CCX design, we see the Ryzen 3 3300X’s Inter-CCX latency as zero as it only has the one CCX. In a lower-is-better scenario, this beats the 3100 and 3600X’s 81 ns and the 1600 AF’s 125 ns. The Ryzen 5 1600 AF’s Inner-CCX latency is also worse at 45 ns versus 33 to 37 ns for the Zen 2 parts, clock speed dependant.

SiSoft Sandra’s Cache and Memory Latency test also highlights latency improvements for the Zen 2 chips versus the 1600 AF that is otherwise proving a tough contender.
