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
Performance Report
At 1080p, performance runs at around 36 FPS. At 1440p, performance is around 36 FPS. At 4K, frame rates range from 19 to 36 FPS.
The GeForce RTX 4090 is 521% above the recommended GPU (GeForce GTX 960) for Dota 2. The Phenom II X3 700e is 77% below recommended, but 39% above minimum.
The Phenom II X3 700e sets the FPS ceiling at all 1080p settings, all 1440p settings, 4k (low/medium/high), while the GeForce RTX 4090 still has headroom. The FPS ceiling is closely matched at 4k ultra.
Approximated average price on current market:
Combo price: $1689. At 1080p Ultra, this combo delivers 36 FPS, equivalent to 0.02 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Phenom II X3 700e sets the ceiling at about 36 FPS, while the GeForce RTX 4090 could reach 169 FPS. In this scenario, the CPU limits the GPU potential by 79% (FPS gap: 133 FPS). Overall distribution: CPU limits 11/12 cells, GPU limits 0/12, balanced 1/12.
Your Phenom II X3 700e 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 79% | CPU Limits GPU 73% | CPU Limits GPU 66% | CPU Limits GPU 54% |
| 1440p (2K QHD) | CPU Limits GPU 68% | CPU Limits GPU 61% | CPU Limits GPU 55% | CPU Limits GPU 32% |
| 4K (Ultra HD) | CPU Limits GPU 45% | CPU Limits GPU 36% | CPU Limits GPU 23% | Balanced |
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.

The Phenom II X3 700e and GeForce RTX 4090 will struggle to run Dota 2 at smooth framerates. At 1080p Ultra, you can expect around 36 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $1689 ($40 CPU + $1649 GPU). 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 Phenom II X3 700e 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.
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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
