Is 32GB DDR5 faster than 16GB at the same speed?

Yes, because larger DDR5 sticks use higher-density chips with more bank groups, which improves throughput by allowing the memory controller to handle more concurrent requests. For example, two 16GB sticks give 8 bank groups per channel versus 4 from two 8GB sticks, making a real difference in memory-heavy tasks like video editing or compiling code. Gaming gains are single-digit at best, but for workstation use, it’s a free speed bump.
