How Much RAM and CPU Does Your Dedicated Server Really Need?

One of the most common questions about dedicated servers: what specs do I actually need? It’s easy to overpay for hardware you’ll never use. Here’s a practical guide based on real-world use cases.

Spec Recommendations by Use Case

Use CaseCPURAMStorage
High-traffic WordPress (500k+ visits/mo)6+ cores64 GB1 TB NVMe
WooCommerce / Magento8+ cores64-128 GB1-2 TB NVMe
Game server (50-100 players)6+ cores (high clock)64 GB500 GB NVMe
Video streaming / transcoding16+ cores128 GB2+ TB NVMe
Database server (MySQL/PostgreSQL)8+ cores128 GB1 TB NVMe (RAID)
Multiple client sites (agency)8+ cores128 GB2 TB NVMe

Don’t Overbuy

If you’re running a single WordPress site with 50,000 monthly visits, you don’t need a 128 GB dedicated server. A $70/month entry-level dedicated server with 64 GB RAM is already overkill for most single sites. Start smaller and scale up.

How to Monitor and Know When to Upgrade

Use tools like htop, netdata, or Grafana to monitor your server. If CPU averages above 80% or RAM usage exceeds 85%, it’s time to upgrade. If both are below 50%, you can safely downgrade to save money.
