The Lenovo IdeaPad 5 I ordered features dual-channel 2x8 RAM at 22V with the Ryzen 7 4800U. My home gaming PC uses 2x16 RAM at 16V with the Ryzen 5 3600X. I’m curious about how gaming and workstation performance will compare. Everything about this laptop has been positive online, even with what seems like slow RAM.
The DDR4 SDRAM 3200C22 sits in the middle range of speeds. Buying from system builders usually means sticking to standard configurations rather than high-end options that might drop as low as C14 at 3200. It's safer to go with typical timings and you won't need to stress too much. Mobile CPUs generally have smaller L3 caches compared to desktop models, which is expected when you trade performance for portability. Most programs don't require minimal latency, so even if you find faster RAM, it may not function properly at those higher speeds unless it's specifically optimized.
OEMs rely on Jedec specifications when picking RAM. This applies to all devices from servers to desktops to laptops. XMP settings such as 3200mhz 16-18-18-38 are essentially overclocking and thus not offered. Tl;dr: the performance is more than acceptable.
This refers to a JEDEC standard, which ensures the CPU and motherboard can handle a specific speed. If they don't meet this requirement, the speed will be seen as an overclock and the manufacturer's rating may be lower.
