Cyberpunk 2077FPS onMobile Sempron SI-40&GeForce RTX 4090

Cyberpunk 2077

The benchmark for modern graphical fidelity. Update 2.0 and Phantom Liberty raised the requirements, making an SSD mandatory. The dense city and NPC AI require strong multi-thread CPU performance. Path Tracing ('Overdrive Mode') is a feature reserved for high-end RTX 40 series cards with Frame Generation.

Official Requirements

The GeForce RTX 4090 is 131% above the recommended GPU (GeForce RTX 2060 Super) for Cyberpunk 2077. The Mobile Sempron SI-40 is 97% below minimum CPU requirement.

⚙️FPS Ceiling Analysis

The Mobile Sempron SI-40 sets the FPS ceiling at 1080p low, while the GeForce RTX 4090 still has headroom. The FPS ceiling is closely matched at 1080p (medium/high/ultra), all 1440p settings, all 4k settings.

Performance Limiter Analysis

Mobile Sempron SI-40|GeForce RTX 4090

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

📈Analysis

This CPU/GPU pair is mostly balanced in Cyberpunk 2077. Across tested presets: GPU limits in 0/12, CPU limits in 1/12, and balanced in 11/12. Peak observed performance in the sampled cells is around 8 FPS.

Verdict

Well Balanced

The Mobile Sempron SI-40 and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.

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 Mobile Sempron SI-40 and GeForce RTX 4090 run Cyberpunk 2077 well?

The Mobile Sempron SI-40 and GeForce RTX 4090 will struggle to run Cyberpunk 2077 at smooth framerates. At 1080p Ultra, you can expect around 2 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.

2Is there a more cost-effective setup to run Cyberpunk 2077?

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 Cyberpunk 2077 performance?

For Cyberpunk 2077, upgrading the CPU would have the biggest impact on performance. The Mobile Sempron SI-40 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.

4Does this setup support Frame Generation for Cyberpunk 2077?

Cyberpunk 2077 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 Cyberpunk 2077?

Cyberpunk 2077 requires at minimum a Core i7-6700 (CPU) and GeForce GTX 1060 (GPU) with 12 GB RAM and 70 GB (SSD) storage. For the recommended experience, you need a Core i7-12700 and GeForce RTX 2060 Super with 16 GB RAM. Your hardware falls below the minimum requirements for this game, which may result in poor performance.

6How accurate are these Cyberpunk 2077 FPS estimates for the Mobile Sempron SI-40 and GeForce RTX 4090?

These Cyberpunk 2077 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.
