板廠沒有透露的秘密 TOPPC，主播隱藏在MSI工作，文本用中文摘要呈现。总结要点：Rocket Lake S（11代）与Alder Lake S（12代）在IMC和DDR4配置上一致，仅支持单频单通道，升级到双IMC及DDR4、DDR4和DDR5后带宽提升，但延迟也随之增加。DDR5x8和x16都能达入门级4800MHz，高频如5600MHz或6400MHz尚不确定。x16相比x8在延迟上更差，但价格更低；若预算紧张，可选择至少2933MHz的x8 DDR4，x16可低频实现。对比x8 DDR4与x16 DDR5在ADL-S上的带宽提升约15%，延迟增加30%。若有x8 DDR5，差距缩小至对带宽影响微小，延迟上升20%。DDR4能匹配DDR5频率的方案成本高，但高时序配置（如Alder Lake S）更实用。建议根据具体应用场景决定，希望有更多测试数据对比不同软件的带宽与延迟表现。

G.Skill Trident Z5 6666mhz offers the quickest memory performance currently available, with 40-40-40-76 nanoseconds and reaching 7000mhz on ambient conditions. Samsung Dies. Success depends on speed, so we push the limits...

For benchmarks, overclocking can be an option. In games, latency takes priority because modern titles are tuned for DDR4 systems with significantly reduced bandwidth. This is why we use DDR and GDDR technologies primarily for performance reasons rather than speed of data transfer.

With DDR5 reaching maturity, overclockers will likely discover methods to reduce latency at increased speeds. Ddr4? I just posted a discussion about sk hynix achieving 3800mhz CL22-24-24 with a 53ns average latency. That suggests a similar experience could be expected with a 7000mhz CL40. DDR5 will simply offer significantly more bandwidth.
