It seems like you're questioning whether a higher-end processor like the 3733 offers real gains over a more affordable option. The price difference is minimal, around $10, and since you're planning to build a Zen 3 system, you might still get good performance benefits from upgrading for a few dollars.
The schedules are set at specific intervals, and it seems the newer option offers improved timing performance compared to the older one.
I assume smaller delays mean improved speed, though I’m unsure how this affects actual results.
The values 3600MHz and 3733MHz have limited effect on overall performance, making a clear conclusion difficult. RAM speed mainly indicates the rate at which it operates when conditions are optimal. For instance, with 3600MHz, the theoretical bandwidth would be around 28.8GBps, while 3733MHz offers approximately 29.87GBps (about 29.866666GBps). This applies under ideal circumstances where the processor needs to read a large sequence of data from RAM, such as moving from memory address 10000000h to 1FFFFFFFh. Under these conditions, 3733MHz can handle up to 29.87GBps compared to 28.8GBps for 3600MHz. However, since RAM operates via random access, it constantly handles numerous read and write operations, which usually prevents reaching such high speeds. In practice, people focus more on CL (clock frequency) or CAS latency—typically measured in clock cycles. This determines how quickly the RAM can begin transferring data after receiving a command from the processor. A lower latency results in quicker response times. Generally, you’ll see about a 10ns delay between receiving a command and starting data transfer. For the 3733MHz model (CL19), this delay is around 10.1ns; for 3600MHz (CL18), it’s 10ns. The 3733MHz RAM also has a slightly better delay than the 3600MHz CL17 at 9.4ns. If you can fine-tune RAM timing, you might achieve 3733MHz performance with CL18 (9.64ns delay). Otherwise, using XMP Profile 2 to run 3600MHz CL17 will still outperform the adjusted 3600MHz CL18 RAM. Nonetheless, in real-world scenarios, noticeable differences are rare.
