1. What is a RAM Speed Comparison Calculator?

Definition: This calculator computes the performance difference between two RAM modules based on their speeds in bytes per second.

Purpose: It helps computer builders and upgraders compare RAM module performance to make informed purchasing decisions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \Delta S \) — Speed difference (bytes per second)
• \( S_1 \) — Speed of first RAM module (bytes/s)
• \( S_2 \) — Speed of second RAM module (bytes/s)

Explanation: The calculator subtracts the slower RAM speed from the faster one to show the performance difference.

3. Importance of RAM Speed Comparison

Details: Comparing RAM speeds helps identify performance bottlenecks and ensures optimal system configuration.

4. Using the Calculator

Tips: Enter the speeds of both RAM modules in bytes per second. Positive results indicate the first module is faster, negative means the second is faster.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert MHz to bytes per second?
A: Multiply MHz by 8 (for 64-bit systems) and then by 1,000,000. Example: 3200 MHz = 3200 × 8 × 1,000,000 = 25,600,000,000 bytes/s.

Q2: What's a significant speed difference?
A: Differences less than 5% (∼1.25GB/s for DDR4) are usually negligible in real-world performance.

Q3: Does this account for latency timings?
A: No, this compares only theoretical bandwidth. For complete comparison, consider CAS latency as well.

Q4: Can I mix different speed RAM modules?
A: Yes, but all modules will run at the speed of the slowest one (unless using XMP profiles).

Q5: How does speed affect real-world performance?
A: Faster RAM benefits CPU-intensive tasks and integrated graphics, with diminishing returns beyond certain thresholds.
