The shared vs. dedicated game server debate has been settled since approximately 2010 for competitive or latency-sensitive games: dedicated wins by a large margin. For casual or turn-based games, the answer is less clear. Understanding the specific performance differences — and why they occur — helps make the right choice for your game type and player expectations.
What “Shared” and “Dedicated” Actually Mean
Shared game server hosting means your game server instance runs on physical hardware shared with other customers’ servers. The CPU, RAM, network, and storage are divided among multiple tenants. Virtualization (VMs or containers) provides isolation, but the underlying resources are competed for.
Dedicated game server hosting means your game server runs on physical hardware reserved exclusively for your use. No other customers share the CPU, RAM, or network. The physical resources are yours entirely.
The distinction matters because game servers have specific resource consumption patterns that interact poorly with shared hosting:
- Real-time game simulation requires consistent CPU scheduling, not just average CPU availability
- Network latency requires physical proximity and low network stack overhead, not just bandwidth
- RAM requirements spike with player count in ways that can exceed shared host limits
The Latency Question
Network latency — specifically round-trip time (RTT) between the player’s client and the game server — is the primary performance metric for real-time games. A first-person shooter requires RTT below 50ms for competitive play; above 100ms, the gameplay experience degrades noticeably.
The latency components:
Physical network latency — the time for packets to travel the physical distance between client and server. This is determined by geography, not hosting model. A shared server in the same data center produces the same base physical latency as a dedicated server in the same data center.
Network stack processing latency — the time for packets to travel through the network stack on the server. Here, shared hosting creates a disadvantage: virtualization adds network processing layers, hypervisor network handling competes with other tenants, and network I/O is shared. A game server on a VM may see 2-5ms additional processing latency compared to bare metal. For casual games, this is imperceptible. For competitive FPS, it’s significant.
CPU scheduling latency — the time for the game server to receive and process a packet after the network stack delivers it. This is where shared hosting fails most visibly for real-time games. The game server process must compete with other VMs’ processes for CPU scheduling. Scheduling jitter — variance in when the game server process gets CPU time — translates directly to inconsistent input processing, visible as “input lag” or “rubber banding” in gameplay.
Where Shared Hosting Works
Turn-based games. If turns take seconds or minutes, the 2-5ms additional latency from shared hosting is completely imperceptible. Chess, card games, strategy games — these work fine on shared hosting.
Low-player-count casual games. A Minecraft server for 10 friends on a shared host runs acceptably well at low player counts. Performance degrades at higher player counts as CPU load grows, and the shared environment has less headroom than dedicated, but for small servers the experience is usually acceptable.
Development and testing environments. Shared hosting for a development or test server where performance doesn’t need to match production is entirely reasonable. Reserve dedicated infrastructure for production player-facing environments.
Budget-constrained small communities. The cost difference between shared and dedicated hosting is real: shared game server hosting typically runs $5-30/month; dedicated bare-metal starts at $50-150/month for entry-level hardware. For a small community running a hobby server, shared hosting at acceptable performance is better than no server at all.
Where Dedicated Is Non-Negotiable
Competitive FPS, battle royale, or any game where fractions of seconds determine outcomes. The scheduling jitter and network overhead of shared hosting are disqualifying. Players will report “bad netcode,” lag, and inconsistent performance — all of which are real performance differences attributable to the hosting environment.
MMO or high player-count servers. As concurrent player count grows, RAM and CPU requirements grow. Shared hosting typically imposes caps that can’t grow with player count. Dedicated hardware scales with your player population.
Games with mod-heavy or resource-intensive configurations. Custom mods, large world sizes, and complex automation systems (Factorio late-game, Minecraft technical servers) push resource usage significantly beyond vanilla server requirements. Shared hosting often can’t accommodate these configurations.
Any server where consistent performance is a community or competitive expectation. If your players have an expectation of professional-grade performance — because you’ve marketed it that way, because you’re running competitive events, or because the community has grown to a scale where bad performance causes churn — dedicated infrastructure is the baseline.
Hardware Specifications That Matter for Game Servers
The specifications that determine game server performance, ranked by importance:
CPU single-core performance. Most game servers are single-threaded or lightly multi-threaded — they benefit from high single-core performance more than many cores. A server with 6 fast cores outperforms one with 16 slower cores for most game workloads. AMD’s Ryzen processors and Intel’s high-clock desktop/workstation chips often outperform server-class CPUs for game server workloads despite having fewer cores.
RAM quantity and speed. RAM requirements scale with player count and game configuration. 16GB is sufficient for most small-to-medium Minecraft servers; 32-64GB for larger or heavily modded servers. RAM speed (MHz) matters more for game workloads than for many other server workloads.
NVMe storage. World data must be loaded from disk as players explore. Slow storage creates the characteristic lag when entering unexplored areas. NVMe SSD is strongly preferred over SATA SSD or (definitely) spinning disk.
Network bandwidth and quality. Bandwidth requirements are modest for most games — 1-5 Mbps per player is typical. The network quality matters more: low latency, low jitter, and no shared-bandwidth congestion from other tenants.
Our game server hosting service runs on dedicated hardware with NVMe storage and uncontended network.
