Dota 2
Dota 2 moved to the Source 2 engine well before CS2. The 'New Frontiers' update expanded the map by 40%, increasing the load on CPU and memory. Unlike LoL, Dota 2 uses more complex models and lighting. It benefits significantly from the Vulkan API, which distributes load better across CPU cores, though it still relies heavily on main core performance. For stable performance in chaotic 5v5 fights, 16GB of RAM is highly recommended.

Performance Summary
The EPYC 7451 + GeForce RTX 4090 pairing runs this title with CPU utilization between 11% and 45% and GPU utilization between 28% and 45%. EPYC 7451 keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 32% at 1080p to 37% at 4K, while CPU averages move from 19% to 25%.
Load Interpretation
Neither component is close to saturation: CPU tops out at 45% and GPU at 45%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput. It also shows why low utilization does not automatically mean there is no FPS limiter.
Resolution Scaling
At 1080p, averages sit around CPU 19% and GPU 32%. At 1440p, that shifts to CPU 21% and GPU 31%, and at 4K it reaches CPU 25% and GPU 37%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
Optimal Settings Recommendation
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 29% (13-45%) and GPU 42% (40-45%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 7451 remains stable for consistent frame delivery.
Upgrade Insight
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 7451 and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.
- High GPU Load: You typically want to see High GPU Utilization (90%+) and moderate CPU usage when visual settings are heavy. This indicates the graphics pipeline is under strong load, but the exact FPS limiter should still be confirmed by the FPS ceiling analysis.
- High CPU Load: If you see High CPU Utilization (85%+) paired with lower GPU utilization, the processor is handling a disproportionate share of frame preparation and game logic. That can point to CPU-side pressure, but it should not be treated as a direct replacement for FPS ceiling analysis.
- Low CPU and GPU Load: If both CPU and GPU utilization are relatively low, it means the hardware is waiting on something else. This could be a game engine limitation, poorly optimized code, or an artificial framerate cap like VSync holding performance back. It does not mean both parts are equally fast in FPS terms.

Frequently Asked Questions
2Is there a more cost-effective setup to run Dota 2?
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 Dota 2 performance?
This setup is already well-balanced for Dota 2. No significant bottleneck - CPU and GPU are well matched across all settings. Both the EPYC 7451 and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
4Does this setup support Frame Generation for Dota 2?
Dota 2 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 Dota 2?
Dota 2 requires at minimum a Core 2 Duo E7400 (CPU) and GeForce 8600 GT (GPU) with 4 GB RAM and 60 GB storage. For the recommended experience, you need a Core i5-2500K and GeForce GTX 960 with 8 GB RAM. Your EPYC 7451 and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
6How accurate are these Dota 2 FPS estimates for the EPYC 7451 and GeForce RTX 4090?
These Dota 2 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.
