Buying a new desktop PC or laptop will usually unveil a list of specs with plenty of jargon. We explain the difference between DDR5 and LPDDR5 RAM.
TL;DR Ryzen laptops with LPDDR5 RAM runs at very low speed (four times slower than advertised) and timings which shoots up memory latency and has poor CPU gaming perfomance as a result. I have a desktop PC with Ryzen 7 7700X and a tuned DDR5 6200 CL30 wi
If cheap no-name DDR5 starts out at 3600 JEDEC specs, that is perfectly fine, because it means that better binned and faster and/or lower latency DIMMs will arrive in short order. But as I said, given what manufacturers have been showing off for a while now I ...
Regarding the DDR5 speed regression, we can only hope that Rockchip will finally address their “stability issues” and figure new reliable settings to run at higher speeds than 2400MHz that are sufficient to recover the performance loss compared to LPDDR4X, otherwise it...
Power Double Data Rate Synchronous Dynamic Random Access Memories (LPDDR SDRAMs) or DRAMS offer high-performance while consuming significantly lower power than standard DDR memories, such as DDR5/4/3, which are ideal for systems requiring large memory capacity. For this reason, LPDD...» read...
