A Source engine sandbox where performance depends entirely on the mods and contraptions you spawn. RAM errors are common on systems with only 4GB.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, frame rates range from 28 to 57 FPS depending on quality settings. At 1440p, frame rates range from 21 to 43 FPS. At 4K, frame rates range from 14 to 28 FPS.
The Radeon HD 8570D + HD 6670 Dual is 62% below recommended, but 282% above minimum for Garry's Mod. The Ryzen 7 7800X3D is 160% above the recommended CPU (Core i5).
The Radeon HD 8570D + HD 6670 Dual sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom.
Approximated average price on current market:
Combo price: $484. At 1080p Ultra, this combo delivers 28 FPS, equivalent to 0.06 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the Radeon HD 8570D + HD 6670 Dual sets the ceiling at about 14 FPS, while the Ryzen 7 7800X3D has headroom up to 130 FPS. In this scenario, the GPU limits the CPU potential by 89% (FPS gap: 116 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon HD 8570D + HD 6670 Dual is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 84% | GPU Limits CPU 85% | GPU Limits CPU 85% | GPU Limits CPU 87% |
| 1440p (2K QHD) | GPU Limits CPU 83% | GPU Limits CPU 85% | GPU Limits CPU 85% | GPU Limits CPU 88% |
| 4K (Ultra HD) | GPU Limits CPU 86% | GPU Limits CPU 87% | GPU Limits CPU 88% | GPU Limits CPU 89% |
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.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 160% below recommended and your GPU is 62% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

The Ryzen 7 7800X3D and Radeon HD 8570D + HD 6670 Dual will struggle to run Garry's Mod at smooth framerates. At 1080p Ultra, you can expect around 28 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $484 ($384 CPU + $100 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the GeForce GTX 1080 SLI (móvel) (Rank #2 for value) could deliver noticeably better performance.
For Garry's Mod, upgrading the GPU would give you the most noticeable improvement. The Radeon HD 8570D + HD 6670 Dual is the limiting factor here, while the Ryzen 7 7800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-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.
Garry's Mod 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.
Garry's Mod requires at minimum a Pentium 4 (CPU) and GeForce 6 series (GPU) with 4 GB RAM and 5 GB storage. For the recommended experience, you need a Core i5 and GeForce GTX 750 with 8 GB RAM. Your setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
These Garry's Mod 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.
