Performance Limiter Analysis

Celeron 877|GeForce RTX 4090

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.

📈Analysis

At 1080p low, the Celeron 877 sets the ceiling at about 20 FPS, while the GeForce RTX 4090 could reach 441 FPS. In this scenario, the CPU limits the GPU potential by 95% (FPS gap: 421 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.

Verdict

CPU Limits GPU

Your Celeron 877 is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.

Percentages show how much potential FPS of the stronger component is lost because the other component has a lower FPS ceiling.
🧠Methodology

We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.

Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.

CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.

A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Frequently Asked Questions

1Can the Celeron 877 and GeForce RTX 4090 run Phasmophobia well?

The Celeron 877 and GeForce RTX 4090 will struggle to run Phasmophobia at smooth framerates. At 1080p Ultra, you can expect around 20 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.

2Is there a more cost-effective setup to run Phasmophobia?

This CPU + GPU combo costs approximately $1664 ($15 CPU + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 7845HX is a great upgrade option (Rank #1 for value).

3Which component should I upgrade first to improve Phasmophobia performance?

For Phasmophobia, upgrading the CPU would have the biggest impact on performance. The Celeron 877 is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.

4Does this setup support Frame Generation for Phasmophobia?

Phasmophobia does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.

5What are the minimum and recommended specs for Phasmophobia?

Phasmophobia requires at minimum a Core i5-4590 (CPU) and GeForce GTX 970 (GPU) with 8 GB RAM and 21 GB storage. For the recommended experience, you need a Core i5-10600 and GeForce RTX 2060 with 8 GB RAM. Your hardware falls below the minimum requirements for this game, which may result in poor performance.

6How accurate are these Phasmophobia FPS estimates for the Celeron 877 and GeForce RTX 4090?

These Phasmophobia FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.

Performance estimates are based on synthetic benchmarks and hardware capabilities.

Results may vary based on drivers, OS, and background processes.
