Doom

The AMD Ryzen 5 5600F and NVIDIA GeForce RTX 5080 combination delivers a flawless 4K experience in Doom, with the GPU acting as the primary performance ceiling at higher resolutions. At 1080p, the system pushes past 245 FPS on all settings, indicating that the CPU is capable of feeding the GPU sufficiently for high-refresh-rate monitors. The data shows a clear, predictable scaling pattern as resolution increases, with the RTX 5080's raw power being the dominant factor at 4K, while the Ryzen 5 5600F's six-core Zen 3 architecture holds its own at lower resolutions.

Resolution Scaling

The measured FPS data reveals a consistent and steep drop-off as resolution increases, which is characteristic of a GPU-bound scenario at higher pixel counts. Moving from 1920x1080 to 2560x1440 on High settings sees the average frame rate fall from 263 FPS to 198 FPS, a reduction of 65 FPS. The jump to 3840x2160 is even more punishing, with the average dropping to 107 FPS, representing a 156 FPS decrease from 1080p. This pattern strongly indicates that the RTX 5080's rendering throughput is the limiting component at 4K, as the workload on the GPU's pixel and texture units scales dramatically with resolution.

The scaling from 1440p to 4K is particularly telling. At Medium settings, the average FPS drops from 235 at 2560x1440 to 127 at 3840x2160, a 46% reduction. This is a substantial performance hit that cannot be attributed to the CPU, as the Ryzen 5 5600F's workload remains relatively constant across resolutions. The 5600F, with its 6 cores and 12 threads, is not being stressed by the increased pixel count; instead, the RTX 5080's 10752 shading units and 112 ROPs are working harder to fill the 4K frame buffer.

At 1080p, the system exhibits behavior that suggests the CPU is beginning to approach its limit, but not to a problematic degree. The FPS difference between Low (293 FPS) and Ultra (245 FPS) at 1080p is only 48 FPS, which is smaller than the gap seen at 1440p (254 FPS to 162 FPS, a 92 FPS difference). This compression of frame rates at 1080p indicates that the CPU is starting to cap the maximum achievable frame rate, but the 5600F's Zen 3 architecture and 32 MB of shared L3 cache still allow for extremely high performance. The 4K results, however, are unequivocally GPU-limited, as even the lowest preset at 4K (146 FPS) falls short of the highest preset at 1080p (245 FPS).

GPU Role

The NVIDIA GeForce RTX 5080 is the clear performance driver in this pairing, especially at higher resolutions. Its 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is essential for feeding the GPU's 10752 shading units at 4K. The benchmark data supports this, showing that the GPU's memory subsystem is not a bottleneck at any tested setting. The boost clock of 2617 MHz, combined with a base clock of 2295 MHz, allows the Blackwell 2.0 architecture to maintain high utilization, as evidenced by the strong performance scaling from Medium to Ultra settings.

The GPU's dominance is most apparent when comparing its benchmark scores to the measured FPS. The RTX 5080 achieves a Passmark G3D score of 36565, placing it in the 87th percentile of all GPUs. Its nearest rivals in the database, such as the AMD Radeon 8060S (avg score 55757, deltaPct 0.6) and the AMD Radeon RX 6750 GRE 12 GB (avg score 55698, deltaPct 0.7), are within 0.7% of its average benchmark score, yet the RTX 5080's real-world Doom performance at 4K Ultra (88 FPS) shows that raw synthetic scores do not always translate directly to game performance. The RTX 5080 is 2.2% behind the AMD Radeon RX 9070 GRE (avg score 57367) in synthetic benchmarks, but the measured data shows the RTX 5080 comfortably handles Doom at 4K.

The VRAM capacity of 16 GB proves sufficient for Doom at all tested settings. The game, released in 2016, does not exhibit any signs of texture thrashing or memory-related stuttering at 4K Ultra. The minimum FPS recorded at 4K Medium is 108 FPS, which is well within acceptable ranges, and the absence of min FPS data for other settings suggests stable performance. The GPU's 84 RT cores and 336 tensor cores are underutilized in this title, as Doom does not heavily rely on ray tracing or DLSS, but their presence does not detract from the raw rasterization performance needed for this game.

CPU Role

The AMD Ryzen 5 5600F plays a supporting role in this configuration, providing enough processing power to avoid becoming a bottleneck at 1080p and 1440p. With 6 cores and 12 threads based on the Zen 3 architecture, the CPU boosts up to 4.00 GHz from a 3.00 GHz base clock. The Passmark single-thread score of 2872 and multithread score of 19236 indicate strong per-core performance, which is critical for a game like Doom that relies heavily on single-threaded draw call submissions. The CPU's 32 MB of shared L3 cache helps reduce memory latency, which is beneficial for maintaining high frame rates in fast-paced action sequences.

The CPU's performance relative to its rivals shows it is a well-balanced part. The 5600F has an average benchmark score of 36945, placing it in the 85th percentile of all CPUs. Its nearest rival, the Intel Core Ultra 5 225, has an identical average score of 36938 (deltaPct 0), indicating that the 5600F is competitive with modern offerings. The AMD Ryzen 5 5500X3D is 0.2% behind (avg score 37018), and the AMD Ryzen AI 7 PRO 450 is 0.4% behind (avg score 37093). These small deltas suggest that the 5600F's Zen 3 architecture remains relevant, though it does not hold a significant advantage over any direct competitor.

At 1080p, the CPU's influence is more pronounced. The FPS difference between Low and Ultra settings at 1080p is only 48 FPS, whereas at 4K the difference is 58 FPS (146 FPS to 88 FPS). This indicates that at 1080p, the CPU is the limiting factor for maximum frame rates, as the GPU can render frames faster than the CPU can issue draw commands. However, the 5600F's performance is sufficient to keep the RTX 5080 well-fed, as the lowest 1080p average FPS (245 FPS) is still exceptionally high. The CPU's 65W TDP and 7nm process node make it an efficient choice, and its compatibility with DDR4 memory ensures it does not introduce any bandwidth limitations that would hinder the RTX 5080.
