DDR5 RAM can operate at a higher frequency on Gen 14 compared to Gen 13.

Hi, your idea is understandable. While Intel processors do improve over time, their performance with fast RAM depends on both hardware and software. If the driver is updated, newer generations like Gen 13 should support higher RAM speeds compared to Gen 14, provided the drivers are compatible. It’s not just about the chip itself but how well it communicates with the system. Let me know if you need more details!

It looks like the same CPUs are involved, which means they share identical limits.
Focusing more on the Silicon Lottery, it's probable there are no updates to the Intel Memory Controller in the 14th Gen "Refresh." Certain chips may possess superior Memory Controllers compared to others. Intel's Specification for the 14th Gen lists a maximum RAM speed of 5600MTS, matching the 13th Gen. Uncertain outcomes
It's about performance differences between CPUs on the same architecture. Generally, a 14th generation processor should perform better in theory, but Intel's memory controller variations mean actual speeds depend more on luck than raw specs. For example, 13th gen chips can reach around 8266MT/s on a 4 DIMM setup, while 14th gen models typically max out near 7200MT/s on the same configuration. Recent studies from Igor's Lab show that the memory controller binning hasn't changed much since the previous generation, though the 13th gen had notable improvements over the 12th.
The 12th gen IMC was really poor, hitting only 6400 on some 4 DIMM boards and working sporadically on the 2 DIMM XOC boards. I’d prefer sticking with 6000 CL30/32 as the top frequency, since there isn’t a huge performance gap between them.
It's quite unusual in the 13th generation that non-K i3 and i5 models are essentially rebranded versions from the 12th generation. They share identical memory controllers and cache designs, though they run slightly faster in clock speed. The 12400 offers overall better performance. The 12400(F) remains a solid processor. If you opt for the B760M PG Riptide board, you can achieve significant speed improvements by overclocking it.
