The hottest advancement in memory technology for desktop computers in recent years is undoubtedly the release of DDR5 memory and Intel's 12th Gen Core series of processors. Not only does DDR5 memory yield higher memory bandwidth for many different use cases, but DDR5 also offers a generational increase in memory capacity, allowing for higher capacity UDIMMs over time.
But, as always, the memory market is anything but homogenous. Even with just three actual DRAM manufacturers, DIMM vendors are offering DDR5 at a slew of clockspeeds, both official JEDEC speeds and X.M.P. profile memory that essentially comes overclocked out of the box. There are also notable differences in today's common DDR5 DIMM configurations, including single-sided UDIMMs (1Rx8), and dual-sided memory (2Rx8), as well as UDIMMs with different capacities.
In today's piece, we're looking at DDR5-4800 memory from Samsung, including 2 x 32 GB, 2 x 16 GB, and 4 x 16 GB, to measure the performance differences between single and dual rank memory, as well as any differences between running DDR5 in one DIMM Per Channel (DPC) or two. Finally, as we have DDR5-4800 DIMMs with DRAM from Micron and SK Hynix, too, we'll also be looking at these in our results, to see if there are any performance differences among the three memory manufacturers.
