Doom

The AMD Ryzen 7 7700 and AMD Radeon RX 6800 XT combination delivers exceptionally high frame rates in Doom, a 2016 FPS title built on a fast-paced engine. The data shows a system that is never stressed by the game's demands at 1080p, with performance scaling predictably as resolution increases. The CPU’s eight Zen 4 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz, provide ample headroom for the game’s logic, while the GPU’s RDNA 2 architecture handles the graphical load with considerable ease. This analysis breaks down the measured performance, contextualizes the combo's ranking, and examines the role each component plays in the final results.

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

The AMD Ryzen 7 7700 is an 8-core, 16-thread processor built on the Zen 4 architecture (codenamed Raphael), manufactured on a 5 nm process by TSMC. Its base clock of 3.80 GHz and boost clock of 5.30 GHz, combined with 32 MB of shared L3 cache, make it a high-performance desktop part. In the context of Doom, a title from 2016 that is not heavily multithreaded, the processor's single-threaded strength is the primary driver of performance. Benchmark data supports this: the CPU scores 1,049 in 3DMark single-thread and 2,525 in Geekbench single-core, while its multithreaded scores (8,484 in 3DMark 16-threads and 18,760 in Cinebench R23 multi-core) are robust but less critical for this specific workload.

The game’s engine is known for scaling well with high clock speeds, and the Ryzen 7 7700’s 5.30 GHz boost ensures that the CPU is rarely a bottleneck at lower resolutions. At 1080p, the measured frame rates are so high that the CPU’s ability to feed the GPU becomes the limiting factor, yet the data shows no signs of stutter or severe drops. The 65 W TDP and dual-channel DDR5 memory support (with 83.2 GB/s bandwidth) are sufficient to keep the pipeline full. Compared to its nearest rivals in the CPU benchmark database, the Ryzen 7 7700 is virtually tied with the AMD Ryzen AI 9 365 (deltaPct of 0.1) and the Intel Core 5 221E (deltaPct of -0.2), indicating that its overall compute capability is evenly matched with those parts. However, for Doom, the raw clock speed advantage of the 7700 is what translates into the high FPS figures observed.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested CPU and GPU combinations for Doom, this specific pairing achieves a rank of 1,158 out of 3,712 combos. This places it in the top 31% of all tested configurations, which is a strong result given the age of the game and the hardware’s relative modernity. The rank reflects that while the RX 6800 XT is a high-end GPU, many newer and more powerful cards (like the NVIDIA GeForce RTX 5070 Ti) have since surpassed it in raw speed, pushing this combo into the upper-middle tier.

The ranking is heavily influenced by the GPU’s performance ceiling, as the CPU is clearly capable of much more. For context, the GPU’s average benchmark score is 48,477, placing it at the 85th percentile of all GPUs, but its nearest rivals show a tight cluster: the NVIDIA RTX A1000 Mobile is 1.5% behind, the Intel Arc A550M is 2.5% ahead, and the RTX 5070 Ti is 3% ahead. This suggests that the RX 6800 XT is a consistent performer, but not a class leader. In Doom, the combo’s rank indicates that it outperforms the majority of systems tested, but it falls short of the very top tier where 4K Ultra settings might yield 100+ FPS. The results are best described as high-refresh-rate capable at 1440p, and solidly playable at 4K.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear and expected scaling pattern as resolution increases. At 1920x1080 with High settings, the combo delivers 215 FPS. Moving to 2560x1440, the frame rate drops to 139 FPS, and at 3840x2160, it falls to 75 FPS. This represents a 65% drop from 1080p to 1440p, and a further 46% drop from 1440p to 4K. The absolute numbers indicate that the GPU becomes the primary limiting factor as resolution climbs.

At 1080p, the CPU’s high boost clock is likely the constraining element, as the GPU is capable of producing over 290 FPS on Low settings. The fact that the 1080p Low setting hits 292 FPS suggests the CPU is near its maximum frame delivery rate for this game. As resolution increases, the GPU’s workload multiplies, and the frame rate drops proportionally. The gap between Low and Ultra settings also widens at higher resolutions: at 1080p, the difference between Low (292 FPS) and Ultra (176 FPS) is 116 FPS, while at 4K, the difference between Low (102 FPS) and Ultra (62 FPS) is 40 FPS. This indicates that at 4K, the GPU is saturated, and the CPU has plenty of headroom. The data clearly shows a balanced system where the CPU handles 1080p and 1440p with ease, while the GPU is the bottleneck at 4K.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality settings. At 1920x1080, the average frame rates are as follows: Low settings yield 292 FPS, Medium yields 254 FPS, High yields 215 FPS, and Ultra yields 176 FPS. The Medium setting has a recorded minimum of 216 FPS and a maximum of 292 FPS, showing a tight frame pacing. These numbers are exceptionally high, making the combo ideal for 240Hz monitors at this resolution, even with Ultra settings.

At 2560x1440, the performance remains excellent. Low settings produce 189 FPS, Medium produces 165 FPS (with a min of 140 and max of 189), High produces 139 FPS, and Ultra drops to 114 FPS. These results indicate that 1440p high-refresh-rate gaming (144Hz or 165Hz) is fully achievable with High settings, and even Ultra settings stay above 110 FPS. The scaling from 1080p to 1440p shows a reduction of roughly 35-40% across all settings, which is typical for an increase in pixel count.

At 3840x2160, the performance is still respectable but begins to dip below the high-refresh-rate threshold. Low settings average 102 FPS, Medium averages 89 FPS (with a min of 76 and max of 103), High averages 75 FPS, and Ultra drops to 62 FPS. For 4K gaming, this means players can comfortably use High settings for a smooth 75 FPS experience, while Ultra settings are playable but not ideal for competitive play. The minimum recorded frame rate at 4K Medium is 76 FPS, which is still above 60 FPS, indicating no severe stuttering. Overall, the data shows a well-balanced system that excels at 1080p and 1440p, with 4K being the only resolution where the GPU’s limits become apparent.

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

The AMD Radeon RX 6800 XT is a high-end graphics card based on the RDNA 2.0 architecture, featuring the Navi 21 chip built on a 7 nm process. It comes equipped with 16 GB of GDDR6 memory on a 256-bit bus, delivering a bandwidth of 512.0 GB/s. The GPU has a base clock of 1825 MHz, a game clock of 2015 MHz, and a boost clock of 2250 MHz. With 4,608 shading units, 288 TMUs, and 128 ROPs, it offers substantial compute power, rated at 20.74 TFLOPS for FP32 operations.

In Doom, the RX 6800 XT’s role is dominant at higher resolutions. The 16 GB of VRAM is more than sufficient for this game, which was released in 2016 and does not have demanding texture requirements. The memory bandwidth of 512.0 GB/s ensures that the GPU can feed its 128 ROPs efficiently, which is crucial for pixel-heavy workloads at 4K. The boost clock of 2250 MHz helps maintain high frame rates, as seen in the 4K High setting averaging 75 FPS. The GPU’s performance is consistent with its database ranking: it scores 24,980 in Passmark G3D and 13,245 in Passmark GPU Compute, placing it at the 85th percentile of all GPUs. Its nearest rival, the NVIDIA RTX A1000 Mobile, is only 1.5% behind in average score, while the Intel Arc A550M is 2.5% ahead, showing that the RX 6800 XT sits in a competitive mid-to-high tier.

The GPU’s 300 W TDP and dual-slot design are typical for a card of this class, but the data suggests that its power draw is justified by the frame rates delivered. At 1080p, the GPU is not fully utilized, as the CPU limits performance, but at 4K, the GPU is the clear bottleneck, and its clock speeds and memory bandwidth are the deciding factors in the final FPS numbers. The card’s support for DirectX 12 Ultimate and Vulkan 1.4 ensures it can handle modern rendering APIs, though Doom primarily uses OpenGL and Vulkan, where the card performs admirably.
