ram speed vs cas latency
ram speed vs cas latency
Looking at recent trends in gaming, speed isn't as crucial anymore. With modern GPUs, reaching higher clock speeds isn't the main concern anymore. Lower latency in the memory path is now more important for smooth performance. So, the Corsair Vengeance 3000 CL 15 offers a good balance of features and stability for today's games.
Consensus reached. Equal latency indicates speed (frequency) matters. More details: CAS Latency is shown in clock cycles. Greater frequency means quicker cycles = reduced absolute latency.
For clarity I will note that the actual RAM speed is half of the stated clock frequency. Therefore a 3600MHz RAM operates at 1800MHz, but due to double data rate it provides two bits per cycle, effectively doubling the real clock. When determining CAS latency you should use the genuine clock value, not the adjusted one.
CAS latency is just one factor among many, and other elements also play a role in final outcomes. It varies depending on the software used, with some performing better under higher latency or bandwidth constraints. I'm not familiar with how modern games handle this behavior. The variations are small and unlikely to determine system success.
