32GB DDR5 can be faster than 16GB, even at the same speed.

Yes, because larger DDR5 sticks use higher-density chips, and those chips typically have more bank groups. More bank groups mean the memory controller can juggle more concurrent requests, which improves throughput.

Here’s the DDR5-specific thing: a 16GB stick uses 16Gb chips, which usually have 8 bank groups. An 8GB stick uses 8Gb chips, which usually have 4 bank groups. Two 16GB sticks give you 8 bank groups per channel (if dual-channel), versus two 8GB sticks giving 4. That’s a real performance difference in memory-heavy tasks like video editing, compiling code, or large file compression.

Gaming? Probably single-digit percent gains at best. But for workstation use, it’s a free speed bump just by picking the bigger sticks.

Don’t let the “more RAM = more work for the controller” myth fool you. DDR5 is designed to scale.
