Solid mid-range CPU (74/100) scores 74.0/100 — adequate for most simulator workloads. How we score
Verdict for X-Plane 12
The AMD Ryzen 9 9900X scores 74.0/100 for X-Plane 12, with CPU performance as the deciding factor at 74% of the fastest gaming CPU in independent tests. Best suited to sim pilots who want strong single-core physics headroom and plan to pair it with a capable GPU — spending more buys X3D cache, not raw clock gains.

Pros & Cons for X-Plane 12
Strengths
- Rated at 74% of the fastest gaming CPU available, the 9900X keeps X-Plane 12's physics thread well ahead during complex blade-element calculations on turboprop approaches into mountainous strips like LOWI — single-core throughput is where this chip earns its place.
- At this price, most competing builds ship with last-generation architectures that lack Zen 5's IPC headroom; the 9900X's modern core design gives the main thread more breathing room during dense VATSIM online sessions where ATC and AI load spikes unpredictably.
- As a standalone CPU purchase, the value score of 195.3 points per $1,000 spent makes this a strong anchor for a phased build — drop it into an AM5 board now, add GPU headroom for photogrammetry-heavy VFR cross-country legs later without touching the socket.
Trade-offs
- X-Plane 12 is more GPU-bound than MSFS 2024, and this is a CPU-only purchase — without a strong discrete GPU alongside it, VR city flyovers over photogrammetry zones like Manhattan will expose the missing GPU headroom long before the 9900X breaks a sweat.
- The next step up in price moves you into X3D cache territory; on dense EGLL arrivals with full AI traffic and Vulkan draw-call pressure, that 3D V-Cache advantage translates to noticeably more consistent frametimes — something the 9900X's conventional cache layout cannot fully replicate.

Frequently Asked Questions
Is this good for X-Plane 12?
The AMD Ryzen 9 9900X scores 74.0/100 for X-Plane 12, driven entirely by its CPU rating of 74 out of 100. It excels during physics-intensive legs — think low-level VFR in turbulent conditions or precise ILS approaches where blade-element theory is running hard on the main thread. Its limits surface in GPU-dependent scenarios like high-resolution photogrammetry zone overflights or VR sessions at full headset refresh, where the bottleneck shifts entirely to whatever GPU you pair with it.
Is it worth the price for X-Plane 12?
With a value score of 195.3 points per $1,000 spent, the 9900X delivers competitive CPU throughput for X-Plane 12 without the premium attached to X3D-cache alternatives. The next step up in price gets you that large L3 cache, which matters most on AI-heavy online networks and dense airport environments — if your flying is mostly solo VFR cross-countries, the gap is harder to justify.
Is X-Plane 12 more CPU or GPU demanding?
This CPU scores 74.0/100 based on raw CPU benchmark performance, measured at 74% of the fastest gaming CPU available in independent 1080p tests. X-Plane 12 is more GPU-dependent than CPU-dependent in practice, meaning the 9900X's single-core strength pays dividends most visibly during physics-heavy scenarios — complex autopilot systems, turbulence modelling, and high AI traffic density — rather than in raw rendering throughput, which lives entirely on the GPU side.
What graphics settings should I use?
Start at 1440p with the High preset in X-Plane 12, using FSR to recover GPU headroom if your paired card needs it — the 9900X is not the bottleneck here, so resolution and visual quality can be pushed relative to the GPU you choose. When the system shows strain, pull back terrain level of detail and AI traffic density first, as those are the CPU-side levers most likely to relieve main-thread pressure during complex approaches.
