Doom

# How This Combo Ranks

The AMD Ryzen 7 9800X3D paired with the NVIDIA GeForce RTX 4080 lands at rank 215 out of 3712 tested combos for Doom. That places this configuration in the top 5.8% of all tested systems, which is an exceptionally strong showing for a game released in 2016. The combination of a high-end 2024 CPU with a 2022 flagship GPU creates a system that sits well above the median tested pair, and the data confirms this is a top-tier setup for this title.

The rank of 215 is particularly notable when you consider the competitive field. The CPU itself sits at the 87th percentile against all processors in the database, while the GPU holds the 86th percentile against all graphics cards. When two components both rank in the mid-to-high 80s in their respective categories, the combined result being inside the top 6% of all combos indicates excellent synergy rather than any bottleneck. The measured FPS data reinforces this, with the system producing triple-digit frame rates even at 4K Ultra settings, which is a demanding workload for any hardware.

Settings Recommendations

The measured FPS data provides a clear picture of how this combo responds to different quality presets. At 1080p, the differences between settings are substantial but the frame rates remain exceptionally high across the board. Low settings produce 401 FPS average, Medium delivers 350 FPS, High drops to 295 FPS, and Ultra still manages 241 FPS. The spread from Low to Ultra is roughly 160 FPS at 1080p, which indicates the GPU scaling is nearly linear with the workload changes.

At 1440p, the pattern continues with Low at 260 FPS, Medium at 226 FPS, High at 191 FPS, and Ultra at 156 FPS. The step-down from Low to Ultra represents about a 40% reduction in frame rate, which is consistent with the increased shader and texture demands of higher presets. The 4K results show Low at 141 FPS, Medium at 123 FPS, High at 104 FPS, and Ultra at 85 FPS.

For the best experience, the data suggests that High settings at 1440p provide the optimal balance. The 191 FPS average at this preset is well above the refresh rate of virtually all gaming monitors, while the visual quality improvement over Medium is meaningful. At 4K, High settings at 104 FPS is the sweet spot — this stays comfortably above 100 FPS while delivering most of the visual fidelity Ultra offers. Ultra at 4K drops to 85 FPS, which is still playable but represents a 18% performance hit over High for what is typically a marginal visual gain in Doom's engine. The Medium preset at 4K, with its 104 FPS minimum and 141 FPS maximum, shows tight frame pacing that makes it a viable alternative if you prefer higher minimums.

Resolution Scaling

The resolution scaling data reveals a system that remains GPU-limited throughout, but with diminishing returns as resolution increases. Going from 1080p to 1440p at High settings, the average FPS drops from 295 to 191, a reduction of 104 FPS or about 35%. Moving from 1440p to 4K at the same settings, the average falls from 191 to 104 FPS, another 87 FPS drop or roughly 46%. The increasing percentage loss at higher resolutions is the classic signature of a GPU-bound scenario.

The Low settings data tells a similar story. At 1080p Low, the system produces 401 FPS, which drops to 260 FPS at 1440p (a 35% reduction) and then to 141 FPS at 4K (a 46% reduction from 1440p). The consistency of these percentages across different quality presets strongly suggests the limiting component is the GPU's fill rate and memory bandwidth rather than CPU throughput. The RTX 4080's 716.8 GB/s memory bandwidth and 280.6 GPixel/s pixel rate are the resources being consumed as resolution increases.

This pattern indicates that the Ryzen 7 9800X3D is not the constraint here. The CPU's 8 cores and 16 threads, boosted by its 96 MB of shared L3 cache, are more than sufficient to feed the GPU at these frame rates. Even at 1080p where frame rates exceed 400 FPS, the CPU benchmarks — including a PassMark multi-thread score of 40009 and a Cinebench R23 multi-core result of 23230 — suggest there is headroom remaining. The 4 nm Zen 5 architecture with its 5.20 GHz boost clock is clearly keeping pace with the RTX 4080.

FAQ

Q: Is this combo overkill for Doom, given the game's age?

A: The data shows this game is demanding enough to scale with modern hardware. At 4K Ultra, the combo produces 85 FPS average, which is not trivially high. The RTX 4080's 16 GB of GDDR6X memory and 9728 shading units are being exercised meaningfully, and the Ryzen 7 9800X3D's 16 threads are put to work at 1080p where frame rates reach 401 FPS.

Q: What settings should I use for competitive play?

A: If maximum frame rate is the priority, Low settings at 1080p deliver 401 FPS average, with Medium at 350 FPS and High at 295 FPS. The step from Low to Medium costs about 13% performance, while High costs another 16%. For competitive play where every frame matters, Low or Medium at 1080p is the data-backed choice.

Q: How does the RTX 4080 compare to its closest rivals in this game?

A: The RTX 4080's average benchmark score of 54247 is nearly identical to the RTX 4080 SUPER at 54209, a delta of just 0.1%. It trails the AMD Radeon Pro W5700X by 1.1% and the AMD Radeon RX 6750 GRE 12 GB by 2.6% in aggregate benchmarks, though in-game results for Doom specifically favor the architecture's strengths.

Q: Can this system handle 4K gaming in Doom?

A: Yes, the measured data shows 4K High at 104 FPS average and 4K Ultra at 85 FPS. Even the most demanding preset stays above 60 FPS, and Medium at 4K hits 123 FPS with a 104 FPS minimum. This is a comfortable 4K experience for this title.

Q: Is the CPU holding back the GPU in this configuration?

A: The resolution scaling data indicates the GPU is the primary limiter. From 1080p to 4K at High settings, FPS drops from 295 to 104, a 65% reduction that tracks with GPU workload scaling. The CPU's Cinebench R23 single-core score of 2080 and PassMark single-thread score of 4430 suggest ample processing headroom.

A: Medium delivers 226 FPS average with a 192 FPS minimum, while High produces 191 FPS average. The 35 FPS difference represents a 15% performance hit for the visual upgrade. Given the High preset still exceeds 190 FPS, the tradeoff heavily favors High for visual quality.

GPU Role

The NVIDIA GeForce RTX 4080 is the workhorse in this configuration for Doom, and the measured frame rates reflect its capabilities. Based on the Ada Lovelace architecture and built on a 5 nm process at TSMC, this GPU packs 45,900 million transistors into a 379 mm² die. The 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is critical for the high-resolution textures Doom can throw at it. The memory clock runs at 1400 MHz, translating to 22.4 Gbps effective.

The GPU's compute resources are substantial: 9728 shading units, 304 TMUs, and 112 ROPs. The texture rate of 761.5 GTexel/s and pixel rate of 280.6 GPixel/s are the raw throughput numbers that explain why this card scales so well across resolution presets. The FP32 performance of 48.74 TFLOPS means the card has massive compute headroom for the lighting and particle effects Doom uses. The boost clock of 2505 MHz and base clock of 2205 MHz are both high for the 40-series, contributing to the card's strong rasterization performance.

In the benchmark database, the RTX 4080 achieves an average score of 54247 and sits at the 86th percentile against all GPUs. Its nearest rival, the RTX 4080 SUPER, scores 54209 — a negligible 0.1% difference that effectively puts them at parity. The AMD Radeon Pro W5700X is 1.1% higher, and the AMD Radeon RX 6750 GRE 12 GB is 2.6% higher in aggregate benchmarks, though in Doom specifically the RTX 4080's architecture advantages in driver optimization and feature support are evident. The 320 W TDP and triple-slot cooler are the price of this performance, with a suggested 700 W PSU.

CPU Role

The AMD Ryzen 7 9800X3D plays the supporting role in this combo, and the data indicates it performs admirably without becoming a bottleneck. This 8-core, 16-thread processor from the 9000 series uses the Zen 5 architecture on the Granite Ridge codename, manufactured on TSMC's 4 nm process. The base clock of 4.70 GHz and boost clock of 5.20 GHz are among the highest in the desktop lineup, and the 96 MB of shared L3 cache is a defining feature for gaming workloads.

The CPU's benchmark results show a well-rounded performer. The Cinebench R23 multi-core score of 23230 and single-core score of 2080 demonstrate strong threading and per-core performance. Geekbench results of 18696 multi-core and 2964 single-core align with expectations for a high-end 2024 desktop part. The PassMark suite shows particular strength in integer math at 116709 and floating-point math at 79456, which are relevant to game logic and physics calculations in Doom.

The 3DMark thread scaling results are telling for gaming use: 2-thread score of 2394, 4-thread at 4669, 8-thread at 8252, and 16-thread at 10081. The scaling from 2 to 8 threads is nearly linear, but the jump from 8 to 16 threads only adds about 22%, suggesting the CPU has sufficient core count for Doom's engine. The single-thread score of 1212 in 3DMark indicates strong IPC that helps maintain high frame rates in CPU-bound scenarios, though the FPS data shows this isn't the limiting factor here.

With an average benchmark score of 39768 and the 87th percentile against all CPUs, the 9800X3D sits in elite company. Its nearest rivals are all within 1%: the AMD Ryzen 7 PRO 8840HS at 39603 (0.4% higher), the AMD Ryzen AI 9 365 at 40048 (0.7% lower), the AMD Ryzen AI 7 450 at 39485 (0.7% higher), and the AMD Ryzen 7 7700 at 40081 (0.8% lower). This clustering shows the 9800X3D is competitive with the best available, and its 120 W TDP is reasonable for the performance delivered. The DDR5 memory support with dual-channel 89.6 GB/s bandwidth ensures the CPU can feed the GPU without memory starvation.
