奶一口,D5时代吃电颗粒CL等主时序也不会超过40,然后纸上谈兵一下:都常规散热的话,用公式「time=CAS Latency÷(以MT/s为单位的传输速率×1000000)」,比较一下商用极限芝奇的DDR4-5333CL22和DDR5-7400CL40的理论延迟可得4.125ns和5.405ns,也就是说早期DDR5的延迟是远不如极限DDR4的。再算一下,前者想达到D4...
RAM’s clock speed is measured in megahertz (MHz), showing how quickly RAM can send data to the CPU. DDR4 RAM usually works at speeds between 2133MHz and 3200MHz. DDR5 RAM, on the other hand, is expected to work at speeds up to 6400MHz. This means that DDR5 RAM will have twice a...
When DDR5 was first announced, many people in the tech community raised an eyebrow at the CAS latency numbers. As it turns out, that was largely a misunderstanding. Latency is actually broadly similar between DDR5 and DDR4, and that’s because the CAS latency number only tells part of the ...
我们以“CL16-18-18-38”这个时序为例,时序中的四个数字分别对应着“CL-tRCD-tRP-tRAS”。 CL(CAS Latency):列地址访问的延迟时间,是时序中最重要的参数 tRCD(RAS to CAS Delay):内存行地址传输到列地址的延迟时间 tRP(RAS Precharge Time):内存行地址选通脉冲预充电时间 tRAS(RAS Active Time):行地址激...
DDR5提升的主要本来就不是CL(CAS latency)和tAA(time after address)，而是tCCD(两次列操作也就是读与...

6. 成本 vs 性能:哪种频率最划算? 服务器租用成本需要平衡性能和预算。以下是大致的成本对比(以 64GB 内存为例): 对于大多数应用,2666MHz 提供最佳的性价比,而 3200MHz 适用于预算充足的 AI/ML 或高性能计算应用。 虽然DDR5 内存已经逐步进入市场,但对香港服务器租用的影响仍需时间: ...
Is upgrading to DDR5 worth it? DDR5 is undeniably an improvement over DDR4 for memory bandwidth and capacity. While it used to have more latency and less support than DDR4, that’s changed. Now, DDR5 is simply faster than DDR4, and DDR4 support is being phased out from the...
As seen in our DDR4 vs DDR5 RAM comparison, there's no need to immediately upgrade to the new standard. But if you're on an older platform, you'll be limited to DDR4 anyway. Let's take a look at a few important things to consider before buying new DDR4 RAM: 16GB RAM is plenty...
