Doom

How This Combo Ranks

The AMD Ryzen 5 5600G paired with the NVIDIA GeForce RTX 4080 ranks 327 out of 3712 tested combos in Doom. This places the configuration in the top 8.8% of all recorded system pairings for this title. The database shows this is a high-performing combination, but the rank also indicates that the CPU, a 6-core, 12-thread Zen 3 part, is a limiting factor when paired with a GPU of this caliber.

The Ryzen 5 5600G sits in the 74th percentile against all CPUs in the database, with an average benchmark score of 21088. Its nearest rivals in synthetic testing are the Intel Core i3-1220P (0.1% faster), the Intel Core Ultra 7 256V (0.1% slower), the AMD Ryzen 5 7530U (0.2% slower), and the Intel Core Ultra 7 155U (0.4% slower). These deltas are negligible, meaning the 5600G's processing power is comparable to a wide range of mobile and low-power desktop chips. For a game like Doom, which relies heavily on single-core performance for its id Tech 6 engine, the CPU's 3.90 GHz base clock and 4.40 GHz boost clock are adequate, but the data suggests the GPU is often waiting on the processor.

The RTX 4080, conversely, is an exceptionally strong GPU. It ranks in the 86th percentile against all GPUs with an average benchmark score of 54247. Its nearest rivals include the RTX 4080 SUPER (0.1% faster), the AMD Radeon Pro W5700X (1.1% faster), the AMD Radeon RX 6750 GRE 12 GB (2.6% faster), and the AMD Radeon 8060S (2.7% faster). The GPU's raw compute power, measured at 48.74 TFLOPS for FP32, is far beyond what Doom requires. This mismatch between the CPU's mid-range standing and the GPU's top-tier standing is the central theme of the measured results.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing. It uses the Ada Lovelace architecture on a 5 nm process from TSMC, with 45,900 million transistors on a 379 mm² die. The GPU has 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s of bandwidth. Its base clock is 2205 MHz with a boost clock of 2505 MHz, and the memory operates at an effective 22.4 Gbps. These specifications provide an enormous amount of headroom for Doom, a title from 2016 that was designed for far less powerful hardware.

The measured frame rates confirm the GPU's capability. At 4K with Low settings, the combo averages 141 FPS, which is already well above the 60 FPS standard for smooth gameplay. The GPU's 76 RT cores and 304 tensor cores are largely irrelevant for Doom, as the game does not use ray tracing or DLSS features. Instead, the game relies on traditional rasterization, where the 112 ROPs and 304 TMUs handle pixel and texture processing. The GPU's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are more than sufficient to push high frame rates at any resolution.

The database indicates that the GPU's role is to provide a massive ceiling that the CPU cannot fully exploit. At 1080p, the frame rates approach the limits of what the CPU can feed, showing a clear bottleneck. At 4K, the GPU still delivers playable frame rates, but the scaling from 1080p to 4K shows a less dramatic drop than would be expected if the GPU were the sole limiting factor. The GPU's 16 GB VRAM is never a constraint in Doom, as the game's textures are well within that capacity, even at Ultra settings.

Resolution Scaling

The measured FPS data reveals a distinct pattern in how the combo scales across resolutions. From 1080p to 1440p, the average frame rates at High settings drop from 295 FPS to 191 FPS, a reduction of 104 FPS. From 1440p to 4K, the High settings average drops from 191 FPS to 104 FPS, another reduction of 87 FPS. The total drop from 1080p to 4K at High settings is 191 FPS, meaning the 4K result is only 35.3% of the 1080p result.

This scaling indicates a CPU bottleneck at lower resolutions. At 1080p, the GPU is so powerful that it can render frames faster than the CPU can process the game's logic and issue draw calls. The 333 FPS at 1080p Low settings is likely near the CPU's maximum throughput for this workload. The Ryzen 5 5600G's 16 MB of L3 cache and dual-channel DDR4 memory bandwidth of 51.2 GB/s are sufficient for Doom, but they are not enough to keep up with the RTX 4080's output at lower resolutions.

At 4K, the GPU becomes more of a limiting factor, but the data shows the CPU still holds it back. The drop from 141 FPS at 4K Low to 104 FPS at 4K High is a 26.2% reduction, which is smaller than the 38.1% reduction seen from 1440p High to 1080p High. This suggests that at 4K, the GPU is finally being utilized more fully, but the CPU's single-thread performance, measured at 872 in 3DMark single-thread and 1409 in Cinebench R23 single-core, still constrains the maximum achievable frame rate.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo's performance across all resolution and settings combinations.

1080p:

• Low settings: 333 FPS average, with no minimum or maximum recorded.
• Medium settings: 317 FPS average, with a minimum of 270 FPS and a maximum of 365 FPS.
• High settings: 295 FPS average, with no minimum or maximum recorded.
• Ultra settings: 241 FPS average, with no minimum or maximum recorded.

At 1080p, the frame rates are extremely high, but the scaling between settings is compressed. The difference between Low and Ultra is only 92 FPS, or 27.6%. This compression is a classic sign of a CPU bottleneck. The CPU cannot generate enough frames to allow the GPU to show its full potential, so raising the graphics settings has a limited impact on the average FPS.

1440p:

• Low settings: 260 FPS average, with no minimum or maximum recorded.
• Medium settings: 226 FPS average, with a minimum of 192 FPS and a maximum of 260 FPS.
• High settings: 191 FPS average, with no minimum or maximum recorded.
• Ultra settings: 156 FPS average, with no minimum or maximum recorded.

At 1440p, the resolution scaling begins to relieve the CPU bottleneck. The drop from Low to Ultra is 104 FPS, or 40.0%, which is a larger percentage than at 1080p. This indicates that the GPU is becoming more involved in the rendering process. The Medium settings row shows a minimum of 192 FPS, which is still far above the 60 FPS threshold for smooth gameplay.

4K (3840x2160):

• Low settings: 141 FPS average, with no minimum or maximum recorded.
• Medium settings: 123 FPS average, with a minimum of 104 FPS and a maximum of 141 FPS.
• High settings: 104 FPS average, with no minimum or maximum recorded.
• Ultra settings: 85 FPS average, with no minimum or maximum recorded.

At 4K, the combo delivers playable frame rates across all settings. The drop from Low to Ultra is 56 FPS, or 39.7%. The Ultra setting's 85 FPS average is still well above the 60 FPS standard, and the Medium setting's minimum of 104 FPS ensures no noticeable stuttering. The 4K results show that the GPU is now the primary driver of performance, but the CPU still imposes a ceiling. The Low setting's 141 FPS is exactly the same as the maximum recorded for the Medium setting, suggesting that the CPU is preventing the GPU from exceeding that threshold.

FAQ

Q: Is the AMD Ryzen 5 5600G a bottleneck for the RTX 4080 in Doom?

A: The data indicates a CPU bottleneck at lower resolutions. At 1080p Low settings, the combo achieves 333 FPS, which is likely near the CPU's maximum. The compressed scaling between settings at 1080p (only 92 FPS difference between Low and Ultra) confirms the CPU limits the GPU's output. At 4K, the bottleneck is less severe, but the 141 FPS ceiling at Low settings suggests the CPU still caps performance.

Q: What is the best resolution to play Doom with this combo?

A: The 1440p resolution offers the best balance. At High settings, the combo averages 191 FPS, which is far above the 60 FPS standard. The 4K resolution also delivers playable results, with an 85 FPS average at Ultra settings. The 1080p resolution is limited by the CPU, so the extra GPU headroom is wasted.

Q: How does the RTX 4080 compare to its nearest rival, the RTX 4080 SUPER?

A: The database shows the RTX 4080 has an average benchmark score of 54247, while the RTX 4080 SUPER scores 54209. The delta is 0.1% in favor of the RTX 4080, meaning the two GPUs are effectively identical in performance. This is within the margin of error for synthetic benchmarks.

Q: Does the Ryzen 5 5600G's integrated graphics affect performance in Doom?

A: The Ryzen 5 5600G includes Radeon Vega 7 integrated graphics, but the system uses the discrete RTX 4080. The integrated graphics do not contribute to the measured FPS in Doom. The CPU's performance is determined by its 6 cores, 12 threads, and 16 MB of L3 cache.

Q: What do the minimum FPS values tell us about frame pacing?

A: The only rows with recorded minimum FPS values are the Medium settings at all three resolutions. At 1080p Medium, the minimum is 270 FPS. At 1440p Medium, the minimum is 192 FPS. At 4K Medium, the minimum is 104 FPS. These values indicate that even the lowest recorded frames are well above the 60 FPS threshold, ensuring smooth gameplay.

Q: How does the CPU's single-thread performance relate to Doom's engine?

A: Doom uses the id Tech 6 engine, which is heavily dependent on single-thread performance. The Ryzen 5 5600G scores 872 in 3DMark single-thread and 1409 in Cinebench R23 single-core. These scores are moderate, and the data shows the CPU cannot feed the RTX 4080 fast enough at lower resolutions.

Settings Recommendations

The measured data suggests that Ultra settings at 1440p offer the best overall experience. The combo averages 156 FPS at that configuration, which is well above the 60 FPS standard and provides headroom for any demanding scenes. The minimum FPS for the Medium setting at 1440p is 192 FPS, so Ultra settings should maintain frame rates above 156 FPS in most scenarios.

For players who prioritize maximum visual fidelity, 4K Ultra is viable, with an average of 85 FPS. This is still above the 60 FPS standard, but the lower headroom means any future driver or game update could cause dips below that threshold. The 4K High setting, averaging 104 FPS, provides a safer margin while still delivering high-quality visuals.

The 1080p resolution is not recommended, as the CPU bottleneck limits the benefit of the RTX 4080. The difference between High and Ultra at 1080p is only 54 FPS, while the same difference at 1440p is 35 FPS. This indicates that the CPU, not the GPU, is the limiting factor at 1080p. The data shows that the combo is best utilized at 1440p or 4K, where the GPU can stretch its legs and the CPU's limitations are less pronounced.

The Low settings at any resolution should be avoided, as they do not provide a meaningful frame rate increase over Medium settings while significantly reducing visual quality. The 4K Low setting's 141 FPS is only 18 FPS higher than the 4K Medium setting's 123 FPS, a marginal gain for a large visual downgrade. The database confirms that the Medium settings offer the most balanced performance, with minimum FPS values recorded at all three resolutions, but the High and Ultra settings remain well within playable ranges.
