Doom

The AMD Ryzen 9 9950X3D paired with the NVIDIA GeForce RTX 2060 is a study in contrast: a top-tier 2025 CPU harnessed to a 2019 mid-range GPU. In Doom, this pairing delivers a playable experience across most settings, but the data clearly shows where the bottleneck lies. The RTX 2060 is the limiting factor at higher resolutions, while the 9950X3D’s immense processing power ensures the frame rate never collapses at 1080p. This combination ranks in the 1389th position out of 1681 tested combos in this game, placing it in the lower-middle tier of the database, which is expected given the GPU's age relative to the CPU's flagship status.

Resolution Scaling

The measured FPS data reveals a classic GPU-bound scaling curve. Moving from 1920x1080 to 2560x1440 at High settings drops the average frame rate from 127.5 FPS to 85.6 FPS, a substantial 32.9% reduction. The jump to 3840x2160 at High settings is even more punishing, halving the 1440p result down to 43.1 FPS. This steep decline indicates that the rendering load is overwhelming the RTX 2060’s capabilities as pixel count increases.

At 1080p, the CPU has enough headroom to push the GPU to its limits. The difference between Low (176.9 FPS) and Ultra (103.8 FPS) at this resolution is 73.1 FPS, showing that the GPU is still the primary constraint even at the lowest settings. However, the scaling from Low to Ultra is not linear, suggesting the GPU is hitting its architectural limits rather than being starved by the CPU.

The 4K results are telling. At 3840x2160, the average FPS ranges from 63.1 on Low to 34.9 on Ultra. The gap between Low and Ultra at 4K is 28.2 FPS, which is proportionally smaller than the 73.1 FPS gap seen at 1080p. This compression of performance at higher resolutions confirms that the RTX 2060 is saturated; no amount of CPU power can compensate for the GPU's inability to process the increased pixel workload.

How This Combo Ranks

Within the database of 1681 tested CPU-GPU combinations for Doom, this pairing sits at rank 1389. This places it in the bottom 17.4% of all tested combos, which is a surprisingly low position given the CPU's pedigree. The ranking is heavily weighted by the GPU's performance, as the RTX 2060 only achieves a 58th percentile score among all GPUs in the database, while the 9950X3D sits in the 96th percentile among CPUs.

The combo's rank is dragged down by the GPU's age. The RTX 2060's average benchmark score of 16074 is nearly identical to its nearest rivals, including the AMD Radeon RX 7600S which scores 15996 (a 0.5% delta) and the AMD Radeon Pro 5700 which scores 16351 (a -1.7% delta). This suggests that the GPU is performing exactly as expected for its class, but that class is simply not competitive in a modern title like Doom when paired with a flagship CPU.

The CPU's contribution to the combo rank is minimal. The 9950X3D's average benchmark score of 71660 is 1.8% higher than the AMD Ryzen 9 9950X (70420) and 2.2% higher than the Intel Core i7-14700KF (70104). Yet, this 2% CPU advantage does not translate into a better combo rank because the GPU is the limiting factor in every measured scenario. The data indicates that the combo rank would improve significantly if the GPU were upgraded, but with the current RTX 2060, the result is a mid-pack finish.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It has a base clock of 4.30 GHz and a boost clock of 5.70 GHz, with a 128 MB shared L3 cache. In Doom, this hardware is vastly overqualified. The game's engine, even at 1080p with Low settings, never comes close to stressing the CPU's capabilities, as evidenced by the 176.9 FPS result.

The CPU's multithreaded performance is exceptional, as shown by its Cinebench R23 multicore score of 59712 and its Passmark multithread score of 70255. However, Doom does not scale to 32 threads effectively. The single-thread performance, measured by a 3DMark single-thread score of 1292 and a Passmark single-thread score of 4737, is more relevant. These scores indicate that the CPU is more than capable of feeding the GPU with draw calls and game logic, but they do not translate into higher FPS when the GPU is the bottleneck.

At 4K Ultra, where the GPU is most stressed (34.9 FPS), the CPU is effectively idle. The 9950X3D's 170W TDP and dual-chiplet design with 16,630 million transistors are wasted on this workload. The data shows that the CPU's role in this combo is to prevent any CPU-side frame drops, which it does flawlessly, but it cannot boost the GPU's performance. Benchmark results indicate that the CPU is not the limiting component in any resolution or settings combination tested.

Measured FPS Breakdown

At 1920x1080, the combo produces its highest frame rates. Low settings yield an average of 176.9 FPS, Medium drops to 151.4 FPS, High to 127.5 FPS, and Ultra to 103.8 FPS. The scaling between settings is consistent, with each step from Low to Ultra reducing performance by roughly 15-20%. This is a smooth, predictable curve that suggests the GPU is handling the workload efficiently without any sudden drops.

Moving to 2560x1440, the performance declines noticeably. Low settings average 114.8 FPS, Medium 99.3 FPS, High 85.6 FPS, and Ultra 65.9 FPS. The gap between 1080p and 1440p at the same settings is significant: Low drops by 62.1 FPS, and Ultra drops by 37.9 FPS. This resolution is where the RTX 2060 starts to struggle, particularly at Ultra settings where the frame rate dips below 70 FPS.

At 3840x2160, the RTX 2060 is clearly overmatched. Low settings produce 63.1 FPS, Medium 50.3 FPS, High 43.1 FPS, and Ultra 34.9 FPS. These numbers are playable at Low and Medium, but High and Ultra are borderline at best. The jump from 1440p to 4K at High settings represents a 50% reduction in frame rate (85.6 to 43.1 FPS), demonstrating the GPU's inability to handle 4K rendering. The 6 GB of VRAM and 192-bit memory bus are simply not sufficient for the texture and shading demands at this resolution.

GPU Role

The NVIDIA GeForce RTX 2060 is built on the Turing architecture with a TU106 chip manufactured on a 12nm process. It features 1920 shading units, 120 texture mapping units, and 48 ROPs, with a base clock of 1365 MHz and a boost clock of 1680 MHz. The GPU has 6 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 336.0 GB/s. These specifications place it in the 58th percentile of all GPUs in the database.

In Doom, the GPU's role is the primary determinant of performance. The 34.9 FPS result at 4K Ultra is a direct consequence of the GPU's 6.451 TFLOPS FP32 compute capability and 80.64 GPixel/s pixel fill rate. The GPU's 30 RT cores and 240 tensor cores are present but underutilized in this non-ray-traced title. The 14 Gbps effective memory speed and 336.0 GB/s bandwidth are adequate for 1080p and 1440p, but they become a bottleneck at 4K where texture bandwidth demands exceed the available memory throughput.

The GPU's benchmark scores corroborate its mid-range status. Its Passmark G3D score of 14111 and 3DMark Steel Nomad DX12 score of 1242 are consistent with its class. The RTX 2060's nearest rivals, the AMD Radeon RX 7600S (0.5% delta) and AMD Radeon Pro 5700 (-1.7% delta), all perform within a 2% margin, indicating that this GPU is performing at its expected level. The data shows that the RTX 2060 is the limiting component in this combo, particularly at resolutions above 1080p.
