Bandwidth vs Latency – Which One Kills Performance?

Your system has fast memory, but your program still lags?
The answer lies in the two most misunderstood concepts in computing:
👉 Bandwidth and Latency.

In this episode of “What Every Programmer Should Know About Memory”, we’ll visually break down the difference between bandwidth and latency — and show how each one impacts your code's performance in completely different ways.

You’ll learn why more GB/s isn’t always better, and how to identify whether your performance bottleneck is due to low bandwidth or high latency.

🧠 What You’ll Learn:
✅ The difference between bandwidth and latency
✅ How each one affects real-world code performance
✅ Examples from RAM, SSDs, GPUs, and networks
✅ Why optimizing for one might worsen the other
✅ How to spot which one is your bottleneck
✅ Practical tips for writing memory-efficient, latency-aware code
