Performance Limiter Analysis

Atom E3845|GeForce RTX 4090

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

📈Analysis

At 1080p low, the Atom E3845 sets the ceiling at about 27 FPS, while the GeForce RTX 4090 could reach 141 FPS. In this scenario, the CPU limits the GPU potential by 81% (FPS gap: 114 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.

Verdict

CPU Limits GPU

Your Atom E3845 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 Atom E3845 and GeForce RTX 4090 run Terraria well?

The Atom E3845 and GeForce RTX 4090 will struggle to run Terraria at smooth framerates. At 1080p Ultra, you can expect around 27 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.

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

Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.

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

For Terraria, upgrading the CPU would have the biggest impact on performance. The Atom E3845 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 Terraria?

Terraria 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 Terraria?

Terraria requires at minimum a Pentium 4 (CPU) and GeForce FX 5900 (GPU) with 2.5 GB RAM and 200 MB storage. For the recommended experience, you need a Core 2 Duo and GeForce 9600 GT with 4 GB RAM. Your hardware falls below the minimum requirements for this game, which may result in poor performance.

6How accurate are these Terraria FPS estimates for the Atom E3845 and GeForce RTX 4090?

These Terraria 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.
