Doom

The AMD Ryzen 7 5800X3D and NVIDIA GeForce RTX 4080 pairing delivers a formidable 4K experience in Doom, with the benchmark data showing a clear path to high-refresh-rate gameplay even at the most demanding settings. This combination of AMD's 3D V-Cache-equipped processor and NVIDIA's Ada Lovelace flagship demonstrates that CPU and GPU headroom are both critical, as frame rates scale dramatically with resolution and preset changes.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5800X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, built on TSMC's 7 nm process. Its base clock of 3.40 GHz and boost clock of 4.50 GHz are complemented by a large 96 MB shared L3 cache, a design choice that pays dividends in game workloads. The processor's benchmark scores place it in the 80th percentile of all CPUs, with an average benchmark score of 27896. This is nearly identical to its nearest rivals, including the AMD Ryzen 7 6800U (avg score 27887, deltaPct 0), Intel Core i9-10900K (avg score 27872, deltaPct 0.1), and AMD Ryzen AI 5 PRO 340 (avg score 27932, deltaPct -0.1). The 5800X3D also edges out the Intel Core i5-12600KF (avg score 27799, deltaPct 0.3).

In the context of Doom, the CPU's role is significant. The measured FPS data shows that at 1920x1080 with Low settings, the combo achieves 339 FPS, but at 3840x2160 with Ultra settings, it drops to 85 FPS. This steep decline across resolutions indicates that while the CPU is more than capable of feeding the GPU at lower resolutions, the GPU becomes the limiting factor as pixel count and graphical fidelity increase. The processor's strong multi-threaded performance — evidenced by a Cinebench R23 multicore score of 14317 and a Passmark multithread score of 28309 — ensures that Doom's engine has ample processing headroom. The 3DMark 16-thread score of 7299 and max-thread score of 7285 are nearly identical, suggesting the processor scales well with full thread utilization. However, the single-thread score of 884 in 3DMark and 1452 in Cinebench R23 single-core indicate that the CPU's per-core performance is solid but not class-leading, which matters for game engines that rely on a few primary threads.

The 5800X3D's memory support is DDR4 with a dual-channel bus, providing 51.2 GB/s of bandwidth. This is sufficient for the game's data streaming needs, though the 96 MB L3 cache is the standout feature here. The benchmark results suggest that the cache helps maintain consistent frame pacing, as the min FPS values at 2560x1440 Medium (192 FPS) and 1920x1080 Medium (274 FPS) are not drastically lower than the average FPS, indicating fewer stutters. Compared to its nearest CPU rivals, the 5800X3D's 96 MB L3 cache gives it a distinct advantage in gaming scenarios, even if its raw compute scores are within 0.3% of the competition.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4080 is the primary driver of Doom's high frame rates, featuring the AD103 chip on a 5 nm process with 45,900 million transistors. Its 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is ample for 4K textures and high-resolution rendering. The GPU's clocks are set at 2205 MHz base and 2505 MHz boost, with memory running at 1400 MHz (22.4 Gbps effective). These specifications translate to a pixel rate of 280.6 GPixel/s and a texture rate of 761.5 GTexel/s, with FP32 compute at 48.74 TFLOPS.

The RTX 4080 sits in the 86th percentile of all GPUs, with an average benchmark score of 54247. Its nearest rivals include the NVIDIA GeForce RTX 4080 SUPER (avg score 54209, deltaPct 0.1), AMD Radeon Pro W5700X (avg score 54828, deltaPct -1.1), AMD Radeon RX 6750 GRE 12 GB (avg score 55698, deltaPct -2.6), and AMD Radeon 8060S (avg score 55757, deltaPct -2.7). The performance delta is minimal, with the RTX 4080 essentially matching the 4080 SUPER within 0.1%, while the AMD competitors score slightly higher in synthetic benchmarks but do not appear in the measured FPS data for this game.

In Doom, the GPU's 16 GB VRAM is a significant asset. At 3840x2160 with Ultra settings, the combo maintains 85 FPS average, which is playable but not ideal for competitive gaming. The jump to High settings at 4K yields 104 FPS, and Medium reaches 123 FPS. The GPU's memory bandwidth of 716.8 GB/s ensures that texture streaming does not bottleneck performance, as evidenced by the consistent frame rates across settings. The RTX 4080's Ada Lovelace architecture, with 9728 shading units and 76 RT cores, provides the raw throughput needed for Doom's id Tech engine. The benchmark results show a clear scaling pattern: at 1920x1080, all settings deliver over 241 FPS, with Low reaching 339 FPS. This suggests the GPU is not the primary constraint at lower resolutions, and the CPU's role becomes more prominent. The RTX 4080's 16 GB memory also future-proofs the system for texture-heavy titles, though Doom specifically does not appear to stress VRAM beyond what the data shows at 4K Ultra.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the combo delivers exceptional frame rates regardless of settings. Low settings achieve an average of 339 FPS, Medium hits 323 FPS (min 274, max 371), High reaches 295 FPS, and Ultra maintains 241 FPS. These numbers indicate that at 1080p, the system is entirely capable of driving high-refresh-rate monitors, with even the most demanding preset staying above 240 FPS.

Moving to 2560x1440, the frame rates remain strong but show a predictable decline as resolution increases. Low settings average 260 FPS, Medium averages 226 FPS (min 192, max 260), High achieves 191 FPS, and Ultra drops to 156 FPS. The min FPS of 192 at Medium settings is particularly notable, as it indicates that the system rarely dips below the 144 Hz threshold, making for a smooth experience on standard 1440p gaming monitors. The gap between Low and Ultra at this resolution is 104 FPS, showing the significant impact of graphical settings on performance.

At 3840x2160, the resolution demands begin to strain the system. Low settings produce an average of 141 FPS, Medium averages 123 FPS (min 104, max 141), High achieves 104 FPS, and Ultra falls to 85 FPS. The 4K Ultra result is the only configuration that drops below 100 FPS, but it remains playable for a single-player FPS. The scaling from Low to Ultra at 4K shows a 56 FPS drop, which is proportionally larger than the 98 FPS drop at 1440p and the 98 FPS drop at 1080p. This indicates that the GPU becomes the primary bottleneck at 4K, while at lower resolutions, the CPU and GPU work in better balance.

The measured data also highlights the consistency of performance. At 1080p Medium, the min FPS of 274 is within 15% of the average of 323. Similarly, at 1440p Medium, the min of 192 is within 15% of the 226 average. At 4K Medium, the min of 104 is within 15% of the 123 average. This consistent frame pacing suggests that neither the CPU nor GPU suffers from significant stutters or thermal throttling in this workload.

How This Combo Ranks

The AMD Ryzen 7 5800X3D + NVIDIA GeForce RTX 4080 combination ranks 323 out of 3712 tested combos in Doom, placing it in the top 8.7% of all systems. This ranking is impressive given the age of the game, which was released in 2016, and the fact that many newer systems may have been tested. The rank reflects the raw power of both components, but it also suggests that the 5800X3D's 3D V-Cache provides a tangible benefit in this title.

Compared to the CPU's nearest rivals, the 5800X3D's performance is nearly identical in synthetic benchmarks, yet the combo rank in-game is what matters. The CPU's 96 MB L3 cache likely helps maintain consistent frame times, which is reflected in the min FPS values. The RTX 4080's rank in the 86th percentile of GPUs further reinforces the system's high standing. The GPU's 16 GB VRAM and 716.8 GB/s bandwidth ensure that Doom's textures load without issue, even at 4K.

The combo's rank of 323 out of 3712 means that only 322 other tested systems outperform it. Given that the RTX 4080 is an end-of-life product and the 5800X3D is also discontinued, this ranking speaks to the longevity of these components. The data shows that this pairing remains competitive in a game that is nearly a decade old, which reflects the brute force of both the CPU and GPU. However, it is important to note that the ranking is specific to Doom; other games may show different relative performance.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target refresh rate and resolution. For 3840x2160, the Medium preset offers the best balance, delivering an average of 123 FPS with a minimum of 104 FPS. This ensures that the game stays above 100 FPS at all times, which is sufficient for most 4K displays that operate at 120 Hz or lower. The High preset at 4K averages 104 FPS, which is also acceptable, but the Medium preset provides a more consistent experience due to its higher min FPS. The Ultra preset at 4K averages 85 FPS, which is playable but may feel less smooth on high-refresh-rate displays.

At 2560x1440, the High preset is the recommended choice, averaging 191 FPS with no reported min FPS below 192. This setting provides near-Ultra visual fidelity while maintaining frame rates well above the 144 Hz threshold. The Medium preset at 1440p averages 226 FPS and is also viable, but High offers better visual quality with minimal performance cost. The Ultra preset at 1440p averages 156 FPS, which is still above 144 Hz, but the High preset's higher average and similar visual quality make it the better option for most users.

For 1920x1080, all settings deliver exceptional performance, with even Ultra averaging 241 FPS. The High preset at 295 FPS is recommended for those with 240 Hz or 360 Hz monitors, as it balances visual quality with high frame rates. The Medium preset at 323 FPS is the best choice for competitive players seeking maximum responsiveness, as the min FPS of 274 ensures no drops below 270 FPS. The Low preset at 339 FPS offers the highest average, but the visual quality trade-off is significant. In summary, the data suggests: at 4K, use Medium for consistent 100+ FPS; at 1440p, use High for 191 FPS average; at 1080p, use Medium or High depending on refresh rate preference.
