Doom

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 3050 4 GB delivers a playable but constrained experience in Doom, with benchmark results showing a clear pattern: the GPU becomes the dominant bottleneck as resolution increases, while the CPU provides ample headroom. The combination ranks 3255th out of 3712 tested configurations in this game, placing it in the lower tier of systems, yet the measured frame rates indicate that the game remains fluid at 1080p and even 1440p with adjusted settings.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 reveals a steep performance curve that points squarely at the graphics card as the limiting factor. At High settings, the average frame rate drops from 100 FPS at 1080p to 65 FPS at 1440p, then falls to 35 FPS at 4K. That represents a 65% reduction in frame rate from 1080p to 4K. The scaling is not linear, however, which indicates that the RTX 3050 4 GB exhausts its capabilities well before reaching 4K.

The Low settings row shows a similar trajectory: 136 FPS at 1080p, 88 FPS at 1440p, and 48 FPS at 4K. The gap between High and Low settings widens as resolution increases, which is a classic sign of pixel-bound rendering. At 1080p, the difference between Low and High is 36 FPS (136 versus 100), but at 4K, that difference shrinks to 13 FPS (48 versus 35). When the GPU is already saturated at 4K, reducing quality settings yields diminishing returns because the raw fill rate and shader throughput are the primary constraints.

The Medium settings row provides min and max frame rate data that further clarifies the bottleneck. At 1080p Medium, the average is 118 FPS with a minimum of 100 FPS and a maximum of 136 FPS. At 1440p Medium, the average drops to 77 FPS with a minimum of 65 FPS and a maximum of 88 FPS. At 4K Medium, the average falls to 41 FPS with a minimum of 35 FPS and a maximum of 48 FPS. The min-to-max spread remains consistent across resolutions, suggesting that frame time variance is not the issue; rather, the absolute throughput is simply insufficient for 4K.

Ultra settings at 1080p produce 82 FPS, which is still playable, but at 1440p Ultra drops to 53 FPS, and at 4K Ultra it bottoms out at 29 FPS. The step from Medium to Ultra at 4K costs 12 FPS, which is a substantial penalty for marginal visual gains. The data indicates that this combo is best suited for 1080p gaming, with 1440p viable only if settings are kept at Medium or below.

GPU Role

The NVIDIA GeForce RTX 3050 4 GB is built on the Ampere architecture with a GA107 chip manufactured on an 8 nm process. The card runs at a base clock of 1545 MHz and a boost clock of 1740 MHz, with memory clocked at 1500 MHz (12 Gbps effective). It has 2048 shading units, 64 texture mapping units, and 32 raster output pipelines, along with 16 ray tracing cores and 64 tensor cores. The memory subsystem consists of 4 GB of GDDR6 on a 128-bit bus, yielding a bandwidth of 192.0 GB/s.

The 4 GB VRAM capacity is the most notable limitation in Doom. While the game itself is not particularly VRAM-hungry at 1080p, the 4 GB buffer becomes a constraint at higher resolutions. The pixel rate of 55.68 GPixel/s and texture rate of 111.4 GTexel/s are modest figures that align with the measured performance. The FP32 throughput of 7.127 TFLOPS is sufficient for 1080p but inadequate for 4K, where the data shows average frame rates in the 30s and 40s.

The card's 90 W TDP and 250 W suggested PSU rating indicate a power-efficient design, but that efficiency does not translate into raw performance headroom. The PCIe 4.0 x8 interface is adequate for this GPU class. The benchmark results show that the GPU reaches its limits at 1440p Ultra, where the 53 FPS average is borderline, and at 4K, where even Low settings only produce 48 FPS. The 4 GB memory size appears to be the primary constraint at 4K, as the performance cliff between 1440p and 2160p is steep regardless of quality settings.

The GPU's percentile ranking against all GPUs is 50, placing it exactly at the median. This aligns with the measured results: it is a mid-range card that can handle esports titles and older AAA games at 1080p, but struggles with modern titles at high resolutions. In Doom specifically, the data shows that the GPU is the limiting component at every resolution above 1080p, as evidenced by the significant frame rate drops when moving from 1920x1080 to 2560x1440.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce an average of 136 FPS, Medium settings yield 118 FPS with a minimum of 100 FPS and a maximum of 136 FPS, High settings achieve 100 FPS, and Ultra settings manage 82 FPS. All settings at 1080p exceed the 60 FPS threshold, and even the most demanding preset stays above 80 FPS.

Moving to 2560x1440, the performance drops noticeably. Low settings average 88 FPS, Medium settings average 77 FPS with a minimum of 65 FPS and a maximum of 88 FPS, High settings average 65 FPS, and Ultra settings average 53 FPS. The step from High to Ultra at 1440p costs 12 FPS, which is a significant penalty for the visual upgrade.

At 3840x2160, the combo struggles to maintain playable frame rates. Low settings average 48 FPS, Medium settings average 41 FPS with a minimum of 35 FPS and a maximum of 48 FPS, High settings average 35 FPS, and Ultra settings average 29 FPS. The data shows that even the lowest quality preset cannot reach 60 FPS at 4K, confirming that this resolution is beyond the GPU's capabilities.

The Medium settings row is the only one with complete min/max data across all three resolutions. At 1080p, the spread from min to max is 36 FPS; at 1440p, it is 23 FPS; at 4K, it is 13 FPS. This narrowing spread at higher resolutions indicates that the GPU is saturated, and frame rates are constrained by the hardware's maximum throughput rather than dynamic scene complexity.

How This Combo Ranks

The combo rank of 3255 out of 3712 systems places this configuration in the lower percentile of tested hardware. This ranking is consistent with the individual component performance: the CPU ranks in the 77th percentile among all processors, while the GPU sits at the 50th percentile. The combination of a strong CPU with a mid-range GPU creates an imbalance that is evident in the game's performance scaling.

The CPU's nearest rivals provide context for its contribution. The AMD Ryzen 5 8400F has an average benchmark score of 25005, which is 0.2% higher than the AMD Ryzen 5 7500F (24964), 0.3% higher than the Intel Core i7-11850H (24935), and 0.4% higher than the Intel Core i7-13620H (24911). The AMD EPYC 9474F scores 25103, which is 0.4% higher than the 8400F. These small deltas indicate that the CPU is not the differentiator in this system's gaming performance.

The ranking relative to other combos suggests that the GPU is the limiting factor. Systems with similar CPUs but faster GPUs would rank significantly higher, while systems with the same GPU but weaker CPUs might rank similarly. The 3255th position out of 3712 indicates that this combo is near the bottom of the performance curve for Doom, which aligns with the measured frame rates at 4K and the GPU's median percentile ranking.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture (Phoenix codename) built on a 4 nm process. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The CPU supports DDR5 memory with dual-channel configuration and a memory bandwidth of 83.2 GB/s.

Benchmark scores indicate strong single-thread and multi-thread performance. The Cinebench R23 multicore score is 20851, and the single-core score is 2943. The 3DMark tests show scaling from 951 (single thread) to 6165 (max threads), with 16-thread performance at 6091. The PassMark multithread score is 24389, and the single-thread score is 3685. The CPU's percentile ranking of 77 places it above the majority of tested processors.

In Doom, the CPU's capabilities are more than sufficient for the GPU's output. The game's engine is well-optimized for multi-threading, and the 6-core/12-thread configuration provides ample processing power. The benchmark data supports this: at 1080p Low settings, the system achieves 136 FPS, which is likely near the CPU's frame generation limit, but at higher settings and resolutions, the GPU becomes the constraint. The CPU's 4.70 GHz boost clock ensures that single-threaded game logic is handled efficiently.

The 8000 series processor with Zen 4 architecture and 4 nm process node represents a modern, efficient design. The 25,000 million transistors on a 178 mm² die are packed into a chip that delivers strong performance per watt. The L3 cache of 16 MB is shared across all cores, which benefits gaming workloads that access shared data. The PCIe Gen 4 support with 20 lanes provides adequate bandwidth for the GPU and storage devices.

Settings Recommendations

For the best experience with this combo, the data points to 1080p as the target resolution. At 1920x1080, all settings presets produce average frame rates above 60 FPS, with High settings at 100 FPS and Ultra at 82 FPS. The High preset offers a good balance between visual quality and performance, providing a 18 FPS advantage over Ultra while maintaining the game's enhanced visuals.

At 1440p, the recommendation shifts to Medium settings. The Medium preset at 2560x1440 averages 77 FPS with a minimum of 65 FPS, which keeps the experience smooth. High settings at this resolution drop to 65 FPS, and Ultra falls to 53 FPS, which may introduce noticeable stuttering in demanding scenes. The 4 GB VRAM capacity is better utilized with Medium settings at 1440p, as the higher presets may exceed the memory buffer.

At 4K, no settings preset achieves a playable frame rate. The highest average is 48 FPS at Low settings, which is below the 60 FPS target. The data suggests that 4K is not viable for this combo, and users should either reduce the resolution or accept sub-60 FPS performance. The Medium preset at 4K produces an average of 41 FPS with a minimum of 35 FPS, which is playable but not ideal for fast-paced action.

The Low settings preset at 1080p delivers 136 FPS, which is ideal for competitive play but sacrifices visual fidelity. The Medium preset at 1080p offers 118 FPS with a minimum of 100 FPS, providing a good compromise for most players. For the best overall experience, the data supports using High settings at 1080p, as it maintains 100 FPS while preserving the game's graphical features that showcase the Doom engine's capabilities.
