Downfall

The AMD Ryzen 5 4600G paired with the AMD Radeon RX 6650 XT delivers a playable experience in Downfall, but the data reveals a system that is heavily constrained by its graphics card at higher resolutions and settings. While the combo handles 1080p and 1440p with ease, pushing to 4K Ultra exposes the GPU’s limits, resulting in a frame rate that barely holds above playable thresholds.

Resolution Scaling

The performance drop from 1080p to 4K in Downfall is steep and clearly indicates that the Radeon RX 6650 XT becomes the primary limiting factor as resolution increases. At Low settings, the average frame rate falls from 199 FPS at 1920x1080 to 88 FPS at 3840x2160, a reduction of 111 FPS. This scaling pattern is typical of a GPU-bound scenario where pixel throughput becomes the bottleneck; the CPU has ample headroom at these settings, but the graphics card's 8 GB of GDDR6 memory and 128-bit bus are taxed heavily by the 4K frame buffer.

The transition from 1440p to 4K produces the most dramatic relative drop. At High settings, the average FPS decreases from 95 at 2560x1440 to 59 at 3840x2160, a 37.9% reduction. Similarly, at Medium settings, the frame rate falls from 116 to 72, a 37.9% drop. This consistent percentage decrease across settings suggests that resolution scaling is the dominant factor, not the complexity of the scene or the specific graphical features enabled.

Interestingly, the gap between 1080p and 1440p is much smaller. At Low settings, 1080p yields 199 FPS while 1440p yields 142 FPS, a 28.6% reduction. This indicates that at lower resolutions, the system is still partially CPU-limited, as the Ryzen 5 4600G’s 6 cores and 12 threads can keep up with the GPU’s output. However, once the resolution crosses into 4K territory, the RX 6650 XT’s rendering capabilities are saturated, and the frame rate scales almost linearly with the pixel count.

The data shows that 4K Medium is the sweet spot for this combo, delivering 72 FPS, while 4K High drops to 59 FPS and 4K Ultra plummets to 37 FPS. This pattern suggests that the GPU’s 2048 shading units and 64 ROPs are insufficient for the most demanding 4K presets, but the card can still manage a smooth experience if the user is willing to compromise on visual fidelity.

GPU Role

The AMD Radeon RX 6650 XT, based on the RDNA 2.0 architecture with the Navi 23 chip, is the defining component for this combo’s performance in Downfall. Its boost clock of 2635 MHz and game clock of 2410 MHz provide the raw compute power needed for this horror title, but the 8 GB of GDDR6 memory on a 128-bit bus with 280.3 GB/s of bandwidth becomes a limiting factor at higher resolutions. The GPU’s 10.79 TFLOPS FP32 performance is respectable for 1080p and 1440p gaming, but the 4K results indicate that the card is stretched beyond its intended design point.

The benchmark scores for the GPU, such as a Passmark G3D score of 17166 and a 3DMark Steel Nomad DX12 score of 1859, place it in the 65th percentile of all GPUs. When compared to its nearest rivals, the data shows a tight grouping: it is 0.6% slower than the NVIDIA Tesla K40m, 0.7% faster than the AMD FirePro D300, 0.7% slower than the AMD FirePro W7000, and 0.8% faster than the NVIDIA Quadro K5200. This indicates that the RX 6650 XT performs as expected for its class, with no significant anomalies in its compute capabilities.

The VRAM capacity of 8 GB is sufficient for Downfall at 1080p and 1440p, where the frame rates are high, but the 4K Ultra result of 37 FPS suggests that memory bandwidth and capacity are strained. The GPU’s pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s are adequate for the game’s horror environments, but the combination of high resolution and Ultra settings overwhelms the memory subsystem. The fact that 4K Low delivers 88 FPS while 4K Ultra drops to 37 FPS shows a 57.9% reduction, highlighting how much the GPU’s memory and shading resources are taxed by the Ultra preset.

How This Combo Ranks

In the overall benchmark database for Downfall, this combination of the AMD Ryzen 5 4600G and AMD Radeon RX 6650 XT ranks 2424th out of 3716 tested combos. This places the system in the 34.8th percentile of all configurations, meaning roughly 65% of tested combos outperform it. This ranking is notable because it indicates that while the individual components are mid-range, the pairing does not boost the system to a top-tier position for this specific game.

The rank suggests that Downfall is more sensitive to GPU performance than CPU performance, as the RX 6650 XT’s 65th percentile ranking among GPUs is significantly higher than the combo’s overall rank. This implies that other combos with weaker CPUs but stronger GPUs are able to achieve better frame rates in this title. The CPU’s 71st percentile ranking among all CPUs does not compensate for the GPU’s limitations at higher resolutions, particularly when the game is run at 4K Ultra.

The data indicates that this combo is better suited for 1080p and 1440p gaming, where it can achieve frame rates well above 60 FPS. At 4K, however, the system falls into the lower half of the rankings, as the GPU becomes the bottleneck. The 2424th rank is a reflection of this behavior, showing that the combo is not optimized for the most demanding scenarios in Downfall. Users with this setup should expect a competitive experience at lower resolutions but should not anticipate leading-edge performance at 4K.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of how this combo performs across different resolutions and settings. At 1920x1080, the system delivers excellent performance: Low settings produce an average of 199 FPS, Medium yields 162 FPS with a minimum of 138 FPS and a maximum of 187 FPS, High settings achieve 133 FPS, and Ultra drops to 83 FPS. The 1080p results show that the combo is capable of high refresh rate gaming, with even the most demanding Ultra preset staying above 80 FPS.

Moving to 2560x1440, the frame rates remain strong but show a noticeable decline. Low settings average 142 FPS, Medium drops to 116 FPS with a range of 99 to 133 FPS, High settings deliver 95 FPS, and Ultra falls to 59 FPS. The 1440p Ultra result is the first point where the system dips below 60 FPS, indicating that the GPU is starting to struggle with the increased pixel count and graphical load.

At 3840x2160, the performance becomes more variable. Low settings still manage a respectable 88 FPS, Medium averages 72 FPS with a minimum of 61 FPS and a maximum of 83 FPS, High drops to 59 FPS, and Ultra plummets to 37 FPS. The 4K results show a clear hierarchy: the system can handle 4K at lower settings, but Ultra is not playable at a smooth frame rate. The jump from Medium to High at 4K costs 13 FPS, while the jump from High to Ultra costs 22 FPS, showing that the Ultra preset imposes a significant additional load on the GPU.

The data also reveals that the frame time consistency, as indicated by the min and max FPS values at Medium settings, is maintained across resolutions. At 1080p Medium, the range is 49 FPS, at 1440p Medium it is 34 FPS, and at 4K Medium it is 22 FPS. This suggests that the game’s frame pacing is stable, but the overall performance ceiling is determined by the resolution and settings combination. For users seeking a locked 60 FPS experience, 4K Medium is the highest resolvable setting, while 1440p High and 1080p Ultra are also viable options.

CPU Role

The AMD Ryzen 5 4600G, with its 6 cores and 12 threads based on the Zen 2 architecture, plays a supporting role in this combo’s Downfall performance. The CPU’s base clock of 3.70 GHz and boost clock of 4.20 GHz provide sufficient single-thread performance for the game’s horror mechanics, as evidenced by its Cinebench R23 single-core score of 1919 and Geekbench single-core score of 1460. The 8 MB of shared L3 cache is adequate for the game’s data requirements, though it is smaller than what is found on higher-end Ryzen parts.

The CPU’s multi-threaded capabilities are solid, with a Cinebench R23 multi-core score of 13593 and a Passmark multithread score of 15992. These scores place the CPU in the 71st percentile of all CPUs, indicating that it is a capable processor for gaming workloads. However, the benchmark results show that the CPU is not the bottleneck in Downfall, as the frame rates at 1080p Low (199 FPS) are well above what the GPU can sustain at higher resolutions. The CPU’s 3DMark scores, including a single-thread score of 726 and a max-thread score of 4889, further confirm that it has ample headroom for this title.

The data suggests that the CPU’s role is to feed the GPU with enough data to maintain high frame rates at lower resolutions. At 1080p, the system is likely CPU-limited at Low and Medium settings, as the GPU is capable of rendering more frames than the CPU can process. However, as resolution increases, the bottleneck shifts to the GPU, and the CPU’s performance becomes less relevant. The Ryzen 5 4600G’s 65W TDP and 7nm process node make it an efficient choice, but its PCIe Gen 3 interface may slightly limit data transfer to the GPU compared to newer Gen 4 platforms, though this impact is not directly measurable in the provided FPS data.
