Doom

The AMD Ryzen 5 3600 paired with the NVIDIA GeForce RTX 4070 delivers a dominant 1080p and 1440p experience in Doom, with performance scaling that reveals a clear GPU bottleneck at higher resolutions. At 4K Ultra, the combo drops to 63.3 FPS, indicating that while the CPU is sufficient for high refresh rates, the GPU becomes the limiting factor when pushing maximum pixels and settings. This pairing ranks in the 70th percentile overall in the database, placing it ahead of a majority of tested configurations for this title.

Resolution Scaling

The measured frame rates show a predictable and steep decline as resolution increases, but the rate of that decline tells a specific story about the system's balance. From 1080p to 1440p, the average FPS across all settings drops by roughly 30-35%, which is a typical scaling curve for a GPU-bound scenario. However, the transition from 1440p to 4K is more punishing, with High settings falling from 152 FPS to 80.6 FPS—a 47% reduction. This disproportionate drop at 4K confirms that the RTX 4070's 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are being taxed heavily, while the CPU's workload remains relatively static.

The data indicates that at 1080p, the combo is almost certainly CPU-limited in some scenarios. At Low settings, the 1080p average of 268 FPS is only 33% higher than the 1440p Low score of 201.5 FPS, suggesting the Ryzen 5 3600's six cores and twelve threads are nearing their ceiling. Conversely, at 4K Ultra, the 63.3 FPS result is a stark contrast to the 1080p Ultra score of 192 FPS, proving that the GPU is the primary constraint when resolution and quality settings are maxed. For users targeting 4K, the scaling shows diminishing returns; the gap between Medium (93.4 FPS) and High (80.6 FPS) is 13.7%, while the gap between High and Ultra (63.3 FPS) is 21.5%, indicating that the Ultra preset demands a significant performance tax.

Settings Recommendations

For a balanced experience prioritizing high frame rates, the High preset is the clear sweet spot for this combo. At 1440p High, the system delivers 152 FPS, which is well above the threshold for smooth competitive play, while at 4K High it still manages a playable 80.6 FPS. The Low preset offers marginal gains over Medium at 1080p (268 vs 255.2 FPS), but the visual sacrifice is not justified when the Medium preset at 1440p still achieves 180.1 FPS.

The Ultra preset is only advisable for 1080p users with high-refresh-rate monitors, where 192 FPS remains excellent. At 1440p, Ultra drops to 119.6 FPS, which is still playable but represents a 21.3% performance loss compared to High. At 4K, Ultra is not recommended, as 63.3 FPS falls below the 70 FPS threshold many players consider minimum for a first-person shooter. The data suggests that Medium at 4K (93.4 FPS) provides a much better experience than Ultra at 4K (63.3 FPS), offering a 47.6% performance uplift with only a moderate visual compromise.

GPU Role

The NVIDIA GeForce RTX 4070 is the workhorse of this pairing, and its specifications directly explain the observed results. With 5,888 shading units, 64 ROPs, and a boost clock of 2475 MHz, the card delivers 29.15 TFLOPS of FP32 compute. This raw power translates to the high frame rates seen at 1080p and 1440p, where the card is not fully saturated. The 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth, which becomes critical at 4K where texture data demands are highest.

The GPU's performance percentile of 81 places it well above average, and its nearest rival in the database is the AMD Radeon RX Vega 56, which scores 0.6% higher on average. This closeness in synthetic benchmarks, however, does not reflect the 4070's advantage in Doom, as the measured FPS shows the card handling the game's Vulkan-based engine with ease. The 200W TDP and dual-slot design are consistent with a mid-range-to-high-end card, and the data confirms it provides ample headroom for 1440p gaming. At 4K Ultra, the card's limitations become apparent, but this is a function of the game's demanding settings rather than a deficiency in the GPU's core architecture.

How This Combo Ranks

This specific CPU-GPU combination ranks 499th out of 1,681 tested combos in Doom, placing it in the top 30% of all systems in the database. This is a strong result, but it is important to contextualize it against the individual components' standings. The RTX 4070 holds an 81st percentile rank among all GPUs, while the Ryzen 5 3600 sits at the 76th percentile among CPUs. The combo's rank is slightly lower than both individual percentiles would suggest, implying that the pairing is not perfectly optimized for this title.

The slight discrepancy is likely due to the CPU's age relative to the GPU. While the Ryzen 5 3600 is a capable processor, its 3.60 GHz base clock and 4.20 GHz boost clock are modest by modern standards. In a game like Doom, which is known for its efficient multi-threading, the CPU's 12 threads are sufficient, but its single-thread performance (Cinebench R23 score of 2,124) may hold back the GPU at lower resolutions. The combo's rank of 499 suggests that many systems with newer, higher-clocked CPUs paired with similar GPUs achieve better results, even if the GPU itself is not the bottleneck.

CPU Role

The AMD Ryzen 5 3600 plays a supporting role in this configuration, and its impact is most visible at 1080p where frame rates are exceptionally high. The processor's six cores and twelve threads, based on the Zen 2 architecture, provide adequate parallelism for Doom's engine. However, the synthetic benchmarks reveal its limitations: a single-thread score of 696 in 3DMark and 2,124 in Cinebench R23 indicate that per-core performance is not elite. This is why the 1080p Low result (268 FPS) is only 14.3% higher than the 1080p High result (233.8 FPS), suggesting that the CPU is beginning to cap the frame rate even at lower settings.

The CPU's 32 MB of shared L3 cache and 51.2 GB/s memory bandwidth are sufficient to feed the GPU's demands at 1440p and 4K, as evidenced by the consistent scaling between those resolutions. The processor's 65W TDP and 7 nm process node make it an efficient choice, but its performance relative to rivals is telling. In the database, the Ryzen 5 3600's average benchmark score of 18,129 is nearly identical to that of the Intel Core i5-11400 (18,150, a -0.1% delta) and the AMD Ryzen 5 7535HS (18,101, a +0.2% delta). These rivals feature higher clocks or newer architectures, yet the 3600 holds its own in synthetic tests. In Doom, the CPU's role is to maintain a stable frame pipeline, and the data shows it succeeds admirably up to 1440p, with 4K performance being almost entirely GPU-bound.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional performance across all presets. The Low setting averages 268 FPS, Medium achieves 255.2 FPS, High hits 233.8 FPS, and Ultra still manages 192 FPS. These numbers indicate that 1080p is well within the system's comfort zone, with even the most demanding preset providing a high-refresh-rate experience.

Moving to 2560x1440, the frame rates remain highly playable. Low averages 201.5 FPS, Medium reaches 180.1 FPS, High delivers 152 FPS, and Ultra drops to 119.6 FPS. The scaling from 1080p to 1440p is consistent, with an average reduction of approximately 30% across settings, confirming that the GPU is the primary driver at this resolution.

At 3840x2160, the system's limits become apparent. Low averages 109.8 FPS, Medium hits 93.4 FPS, High produces 80.6 FPS, and Ultra falls to 63.3 FPS. The gap between High and Ultra at 4K (17.3 FPS) is the largest absolute difference between any two consecutive presets at a single resolution, highlighting the Ultra preset's heavy reliance on GPU resources. For 4K gaming, users should stick to Medium or High to maintain frame rates above 80 FPS.
