Doom

The Intel Core Ultra 5 235 and NVIDIA GeForce RTX 2060 combination delivers a playable but inconsistent experience in Doom, with performance scaling that clearly identifies the GPU as the primary bottleneck at higher resolutions. Benchmark results show this pairing ranks 2294th out of 2930 tested combos, placing it in the lower third of systems. The data indicates that while the CPU provides ample headroom for high frame rates, the aging RTX 2060 struggles to maintain smooth performance at 4K, forcing users to rely on lower settings for acceptable frame rates.

CPU Role

The Intel Core Ultra 5 235 brings substantial processing power to this pairing, featuring 14 cores and 14 threads with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. This Arrow Lake-S architecture chip, built on a 3 nm process by TSMC, delivers strong single-threaded performance that matters for Doom's engine. In Cinebench R23, the CPU scores 2085 in single-core and 14769 in multi-core tests, indicating robust capability for both lightly-threaded game logic and background tasks. The 24 MB of shared L3 cache and DDR5 memory support with 102.4 GB/s bandwidth provide the data throughput necessary for modern game engines.

The CPU's benchmark percentile of 89 versus all CPUs places it in the top tier of processors, and its average benchmark score of 46062 puts it nearly identical to the AMD Ryzen AI 9 HX 375 (46030, 0.1% delta) and Intel Core i9-13900HX (46098, -0.1% delta). This means the Ultra 5 235 is effectively on par with these high-end rivals in synthetic workloads, offering no meaningful advantage or disadvantage in raw compute. For Doom specifically, the game's id Tech 6 engine is known for scaling well with strong single-thread performance, and the CPU's 5.00 GHz boost clock should prevent any processor-induced frame pacing issues.

Looking at the measured FPS data, the CPU's influence becomes apparent when examining frame rates across different resolutions. At 1080p Low settings, the combo achieves 175 FPS average, which approaches the ceiling of what many displays can show. The fact that performance drops to 129 FPS at 1080p High and 105 FPS at 1080p Ultra suggests the GPU is already becoming the limiting factor even at lower resolutions. The CPU's PassMark single-thread score of 4516 and multithread score of 37816 indicate it can comfortably feed the GPU with draw calls and physics calculations without becoming a bottleneck.

The 14-core, 14-thread configuration without hyperthreading is notable, as each core handles one thread. This design choice, combined with the 3 nm process, results in a 65 W TDP that keeps thermals manageable. In Doom's fast-paced combat scenarios, the CPU's rapid response to input and consistent frame time generation should not be a concern, as the benchmark data shows no evidence of CPU-induced stuttering or frame drops at any tested resolution.

GPU Role

The NVIDIA GeForce RTX 2060 is clearly the limiting component in this system, and the benchmark data reflects this reality. This Turing-architecture GPU, built on a 12 nm process at TSMC, features 1920 shading units, 120 texture mapping units, and 48 ROPs. Its 6 GB of GDDR6 memory on a 192-bit bus provides 336.0 GB/s of bandwidth, which becomes a critical constraint at higher resolutions and quality settings. The GPU's boost clock of 1680 MHz and base clock of 1365 MHz are modest by modern standards, and its 6.451 TFLOPS of FP32 performance places it firmly in the mid-range segment.

The RTX 2060's benchmark percentile of 58 versus all GPUs places it in the middle of the pack, with an average benchmark score of 15290. Its nearest rivals include the NVIDIA GeForce GTX 580 (15283, 0.0% delta), AMD Radeon 680M (15270, 0.1% delta), and NVIDIA GeForce RTX 3050 OEM (15199, 0.6% delta). This clustering shows the RTX 2060 performs nearly identically to these alternatives, meaning users should not expect any significant advantage from this GPU in Doom. The 30 RT cores and 240 tensor cores are present but largely unused in Doom, as the game does not support ray tracing or DLSS.

The GPU's memory configuration is the most significant weakness. The 6 GB VRAM capacity, while sufficient for 1080p gaming, becomes strained at 1440p and especially 4K resolutions. The measured FPS data shows the GPU's performance ceiling: at 1080p Low, the combo hits 175 FPS, but this drops to 45 FPS at 4K High. The 14 Gbps effective memory speed and 336 GB/s bandwidth are adequate for the game's textures at lower settings, but Ultra settings at 4K likely exceed the GPU's memory bandwidth and capacity, resulting in the 37 FPS average observed. The GPU's 80.64 GPixel/s pixel rate and 201.6 GTexel/s texture rate provide context for why quality settings have such a dramatic impact on performance.

Resolution Scaling

The resolution scaling data reveals a clear pattern of GPU-bound performance, with frame rates dropping dramatically as resolution increases. At 1080p, the combo delivers excellent performance across all settings: 175 FPS at Low, 152 FPS at Medium, 129 FPS at High, and 105 FPS at Ultra. Moving to 1440p, these numbers fall to 113 FPS at Low, 99 FPS at Medium, 83 FPS at High, and 68 FPS at Ultra. The scaling from 1080p to 1440p shows approximately a 35-40% performance reduction, which is consistent with a GPU-bound scenario where the increased pixel count directly impacts fill rate.

The jump to 4K is where the RTX 2060's limitations become severe. At 3840x2160, the combo manages only 61 FPS at Low settings, 53 FPS at Medium, 45 FPS at High, and 37 FPS at Ultra. The drop from 1440p to 4K represents a 45-50% reduction in frame rates, which is steeper than the pixel count increase would suggest. This indicates that the GPU is not just fill-rate limited but also struggling with memory bandwidth and capacity at 4K. The 6 GB VRAM likely causes texture swapping and compression overhead, further reducing performance beyond what raw pixel throughput would predict.

The limiting component analysis is straightforward: the CPU has ample headroom, as evidenced by the fact that even at 4K Low settings, the combo achieves 61 FPS, which is still above the 60 FPS threshold for smooth gameplay. If the CPU were the bottleneck, we would expect to see frame rates plateau across resolutions, but instead they scale consistently with resolution changes. The GPU's percentile ranking of 58 versus all GPUs, combined with its modest 6.451 TFLOPS FP32 performance, confirms that the RTX 2060 is the constraining factor. Users seeking higher frame rates at 1440p or 4K would need a more powerful GPU, as the data shows the CPU can handle significantly more work than the GPU can deliver.

How This Combo Ranks

The combination of the Intel Core Ultra 5 235 and NVIDIA GeForce RTX 2060 achieves a rank of 2294 out of 2930 tested combos in Doom, placing it in the bottom 22% of all systems. This ranking is heavily influenced by the GPU's performance, as the RTX 2060's percentile of 58 versus all GPUs is significantly lower than the CPU's percentile of 89 versus all CPUs. The discrepancy between the CPU and GPU percentiles highlights the imbalance in this pairing, where a high-performing processor is paired with a mid-range graphics card from a previous generation.

The GPU's nearest rivals provide context for its performance tier. The RTX 2060's average benchmark score of 15290 is virtually identical to the GTX 580 (15283, 0.0% delta) and AMD Radeon 680M (15270, 0.1% delta), while being only 0.8% ahead of the AMD Radeon RX 7600 (15171). This clustering means that in Doom, the RTX 2060 performs similarly to integrated graphics solutions and older high-end GPUs, which explains why the combo ranks so low despite having a modern CPU. The CPU's nearest rivals, including the AMD Ryzen AI 9 HX 375 and Intel Core i9-13900HX, are all high-end processors, but the GPU's limitations prevent the system from achieving higher rankings.

The measured FPS data at 1080p Ultra (105 FPS average) and 1440p High (83 FPS average) shows that the combo can deliver playable performance at lower resolutions, but it cannot compete with systems featuring more powerful GPUs. The ranking of 2294/2930 suggests that approximately 78% of tested combinations outperform this setup in Doom, which is consistent with the RTX 2060 being several generations old and having only 6 GB of VRAM. For users considering this combo, the data indicates that the CPU is capable of supporting a much more powerful GPU, and the system's overall ranking would improve significantly with a graphics card upgrade.

Settings Recommendations

The benchmark data provides clear guidance on which settings deliver the best balance of visual quality and performance for this combo. At 1080p, the system can handle Ultra settings with an average of 105 FPS, which is smooth and visually impressive. However, the 1080p Medium settings offer a better experience with 152 FPS average and a minimum of 130 FPS, providing significant headroom for demanding scenes while maintaining high visual fidelity. The 1080p High settings at 129 FPS average are also excellent, but Medium provides a 23 FPS improvement over High with only a modest reduction in visual quality.

For users with 1440p displays, the recommended setting is Medium, which delivers 99 FPS average with a minimum of 84 FPS. This provides a smooth experience that stays above the 60 FPS threshold even during intense combat sequences. The 1440p High settings at 83 FPS average are also playable, but the 16 FPS drop from Medium to High makes Medium the safer choice for consistent performance. The 1440p Ultra setting at 68 FPS average is borderline, and users who prioritize visual quality over frame rate consistency may find it acceptable, but the 1440p Medium setting offers the best overall experience.

At 4K, the system struggles to maintain playable frame rates at higher settings. The 4K Low settings achieve 61 FPS average, which is just above the 60 FPS threshold, making it the only viable option for smooth 4K gameplay. The 4K Medium settings at 53 FPS average are playable but will experience noticeable stuttering during fast-paced action, while the 4K High and Ultra settings at 45 FPS and 37 FPS respectively are not recommended for competitive play. For the best experience, users should prioritize 1080p Medium or 1440p Medium, as these settings provide the highest frame rates while maintaining acceptable visual quality, and they avoid the significant performance penalties associated with 4K rendering on this GPU.
