| Memory Frequency | DDR5-6000 | DDR5-6000 |
| Bandwidth | Higher | Lower |
| Latency | Lower | Higher |
| Overall Performance | Slightly better | Slightly worse |
The exact performance gap between CL30 and CL32 can change based on many factors. For example, G.Skill’s Trident Z5 Neo AMD DDR5-6000 kits come in both CL30 and CL32. But, we don’t have specific results for these kits yet.
Choosing between CL30 and CL32 DDR5 RAM depends on your needs. If you want the lowest latency, go for CL30. But if you’re looking for a balance of performance and price, CL32 might be better.
Memory Speed and Bandwidth Analysis
Memory performance is key, with memory bandwidth and read/write speeds being crucial. DDR4 memory kits usually run at 3000-3600 MT/s. DDR5 memory is best at 6000-6400 MT/s for most tasks.
We tested memory timings by comparing CAS Latency (CL) 30 and CAS Latency 32. Moving from a 4800 MT/s kit to a 6400 MT/s kit with the same latency boosted read/write performance by 37-40%. Going from CL40 to CL32 at the same speed improved read/write scores by 30%.
Read/Write Performance Metrics
Our latency testing showed that lower CAS latency means faster memory. But, how it affects real-world application performance can differ. Some programs are more affected by memory speed and bandwidth than others.
Latency Testing Results
In Geekbench, a CPU-focused benchmark, increasing frequency had a bigger impact on multi-thread scores. But, latency improvements didn’t greatly change overall scores. This means memory speed and bandwidth are key for some tasks, while latency is more important for others.
Real-world Application Impact
For gaming, DDR5-6000 CL30 is a good choice, balancing performance and cost. But, tasks that need more speed might require DDR5-6400 to DDR5-8000. This depends on your budget and what your system can handle.
SK Hynix Die Types and Their Characteristics
DDR5 RAM’s performance depends on SK Hynix die types. The Hynix-A and Hynix-M are two main types. Each has unique features that affect DDR5 RAM ICs.
The Hynix-A die is rare but offers great benefits. It has better CAS latency and can reach high clock speeds. This makes it ideal for those who want top performance. But, finding these modules can be hard.
The Hynix-M die is more common in DDR5-4800 kits. It has longer tRC times but scales well with voltage. This makes it good for users who want a balance of performance and ease of finding.
| Die Type | Characteristics | Availability | Performance Implications |
