GoKawiilDDR5 speed ratings explained: why higher numbers don't always mean faster memory
DDR5 memory kits are labeled with a data rate (in millions of transfers per second) and a CAS latency figure, which together determine actual response time rather than clock speed alone. JEDEC's standard timings keep real latency close to 14 nanoseconds across speeds from DDR5-3200 to DDR5-8800, meaning faster-rated kits with looser timings aren't necessarily quicker to respond, just capable of moving more data once it starts flowing. Premium kits distinguish themselves by tightening CAS latency at a given speed or pushing to higher speeds like DDR5-9600.
