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.
Actual FPS may vary based on RAM speed, background processes, and other system factors

At 4k medium, the Core i7-9700K sets the ceiling at about 253 FPS, while the GeForce RTX 4090 could reach 357 FPS. In this scenario, the CPU limits the GPU potential by 29% (FPS gap: 104 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i7-9700K is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 22% | CPU Limits GPU 19% | CPU Limits GPU 16% | CPU Limits GPU 19% |
| 1440p (2K QHD) | CPU Limits GPU 24% | CPU Limits GPU 27% | CPU Limits GPU 23% | CPU Limits GPU 24% |
| 4K (Ultra HD) | CPU Limits GPU 25% | CPU Limits GPU 29% | CPU Limits GPU 25% | CPU Limits GPU 27% |
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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Core i7-9700K + GeForce RTX 4090 pairing runs this title with CPU utilization between 24% and 63% and GPU utilization between 42% and 84%. Core i7-9700K keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 56% at 1080p to 64% at 4K, while CPU averages move from 44% to 39%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 70% average at its highest-load preset, while the Core i7-9700K peaks at 48% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 44% and GPU 56%. At 1440p, that shifts to CPU 37% and GPU 64%, and at 4K it reaches CPU 39% and GPU 64%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 47% (31-63%) and GPU 70% (56-84%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i7-9700K remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i7-9700K and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Core i7-9700K paired with the GeForce RTX 4090 can run Dota 2 smoothly up to 4k achieving around 184 FPS at Ultra quality. Your GPU is 521% above the recommended specs, and your CPU is 125% above the recommended requirements.
This CPU + GPU combo costs approximately $1849 ($200 CPU (Rank #274 Value) + $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 9950X is a great upgrade option for around $649 (Rank #5 for value).
For Dota 2, upgrading the CPU would have the biggest impact on performance. The Core i7-9700K 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.
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.
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 Core i7-9700K and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
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.
