Downfall

# Downfall Performance Analysis: AMD Ryzen 5 4600G + AMD Radeon RX 7900 XTX

The pairing of a Zen 2-based Ryzen 5 4600G with AMD's flagship RDNA 3 GPU, the Radeon RX 7900 XTX, creates an intriguing asymmetry in this horror title. The CPU is a 6-core, 12-thread processor from the 4000 series, built on a 7 nm process with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. The GPU, meanwhile, is a 5 nm Navi 31 chip with a boost clock of 2498 MHz and 24 GB of GDDR6 memory on a 384-bit bus. The data shows this combination ranks 288th out of 1741 tested combos in Downfall, placing it in the top 16.5% of all configurations. That rank is respectable, but the measured frame rates reveal a more complex story about where the bottleneck lies.

CPU Role

The Ryzen 5 4600G's Zen 2 architecture provides six physical cores and twelve threads, with an 8 MB shared L3 cache. Its single-thread performance, as measured by Cinebench R23, is 1919 points, while multi-core reaches 13593 points. In the context of Downfall—a horror game that typically relies on consistent frame pacing rather than extreme multi-threading—these scores suggest the CPU is adequate but not exceptional. The processor's 3DMark single-thread score of 726 and 2-thread score of 1430 indicate that per-core performance is modest by modern standards. This becomes relevant when examining the frame rate ceiling at lower resolutions.

The CPU sits at the 75th percentile among all processors tested, with an average benchmark score of 17489. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE (avg score 17482, delta 0%), the Intel Core i5-12450H (17475, +0.1%), and the Intel Core i3-14100T (17636, -0.8%). The deltaPct values show these are essentially performance peers, meaning the 4600G is not a standout in either direction. For a horror title like Downfall, the 12 threads can handle background tasks and game logic, but the relatively modest single-core throughput may cap performance when the GPU is not the limiting factor. The data suggests that at 1080p, where the GPU has less work, the CPU's capabilities become more prominent in determining final frame rates.

GPU Role

The Radeon RX 7900 XTX is a different beast entirely. With 6144 shading units, 384 TMUs, and 192 ROPs, it delivers 61.39 TFLOPS of FP32 compute. The 24 GB of GDDR6 memory runs at 2500 MHz (20 Gbps effective) across a 384-bit bus, yielding 960.0 GB/s of bandwidth. This is a GPU designed for maximum rasterization throughput, and its benchmark scores reflect that: a Passmark G3D score of 31238 and a 3DMark Steel Nomad DX12 score of 6841. The GPU sits at the 85th percentile among all GPUs, with an average benchmark score of 44019.

Its nearest rivals include the AMD Radeon Pro 580 (44195, -0.4%), the NVIDIA GeForce RTX 4090 Mobile (43667, +0.8%), and the NVIDIA Quadro M6000 (43313, +1.6%). The deltaPct values here are telling—the RX 7900 XTX is within 2% of these competitors, meaning it is firmly in the high-end tier. For Downfall, the massive memory bandwidth and compute power suggest the GPU can handle even the most demanding settings without breaking a sweat. The 96 ray accelerators (RT cores) are present but likely underutilized in this title, which is more about atmosphere than ray-traced reflections. The GPU's role in this combo is to deliver high frame rates across all resolutions, and the data confirms it does so—except when the CPU holds it back.

Resolution Scaling

The measured FPS data reveals distinct scaling patterns across resolutions. At 1920x1080 with Low settings, the combo hits 296.3 FPS. Moving to 2560x1440 Low, it drops to 257.3 FPS (-13.2%), and at 3840x2160 Low, it falls to 164 FPS (-36.3% from 1440p). This scaling is relatively gentle, suggesting the GPU is still the primary driver even at 4K. However, the picture changes when examining High settings: 1080p High yields 245.5 FPS, 1440p High gives 172.9 FPS (-29.6%), and 4K High drops to 109.2 FPS (-36.8% from 1440p). The larger percentage drop from 1080p to 1440p at High settings hints that the CPU may be limiting the 1080p result—245 FPS is high, but the gap to the 296 FPS Low setting shows headroom exists.

At Ultra settings, the trend becomes more pronounced. The 1080p Ultra result is 149.9 FPS, 1440p Ultra is 105.9 FPS (-29.4%), and 4K Ultra is 71.2 FPS (-32.8% from 1440p). The 4K Ultra figure of 71.2 FPS is the lowest measured, and the drop from 1080p to 4K at Ultra is 52.5%. This suggests that at Ultra settings, the GPU becomes the clear limiting factor, as the CPU is less able to keep up with the increased pixel workload. Conversely, the relatively small gap between 1080p Low and 1440p Low (296.3 to 257.3) indicates the CPU is holding back the 1080p result, since the GPU should be capable of far more at that resolution.

How This Combo Ranks

The combo rank of 288 out of 1741 tested combos places this configuration in the top 16.5% of all pairings tested in Downfall. This is a strong showing, but it is not the top tier one might expect given the GPU's capabilities. The rank suggests that while the RX 7900 XTX is a powerful GPU, the Ryzen 5 4600G's modest single-core performance prevents this combo from reaching the upper echelons. For comparison, the CPU's nearest rivals all have similar average scores, which means swapping the 4600G for an Intel Core i3-14100T or i3-13100F would likely yield nearly identical results in this game.

The GPU's rank is more impressive—85th percentile among all GPUs—but the combo rank is dragged down by the CPU. This is consistent with the resolution scaling analysis: at 1080p, the CPU is the bottleneck, and at 4K, the GPU takes over. The fact that the combo still ranks 288th indicates that the GPU's raw power compensates for the CPU's limitations at higher resolutions. The data implies that a stronger CPU (one with higher single-thread scores) would push this combo significantly higher in the rankings, particularly at 1080p and 1440p.

Measured FPS Breakdown

At 1920x1080, the frame rates are consistently high across all settings. Low settings produce 296.3 FPS, Medium drops to 272.9 FPS (-7.9% from Low), High yields 245.5 FPS (-10.0% from Medium), and Ultra falls to 149.9 FPS (-38.9% from High). The jump from High to Ultra is the most severe, indicating that Ultra settings introduce a significant additional workload that the CPU cannot fully feed.

At 2560x1440, the pattern shifts. Low gives 257.3 FPS, Medium gives 210.3 FPS (-18.3%), High produces 172.9 FPS (-17.8%), and Ultra drops to 105.9 FPS (-38.8% from High). The percentage drops between Medium and High are larger at 1440p than at 1080p, suggesting the GPU is starting to feel the load. The Ultra setting at 1440p (105.9 FPS) is still playable but represents a substantial reduction from the 149.9 FPS seen at 1080p Ultra.

At 3840x2160, the results are the most demanding. Low yields 164 FPS, Medium drops to 130.5 FPS (-20.4%), High gives 109.2 FPS (-16.3% from Medium), and Ultra falls to 71.2 FPS (-34.8% from High). The 4K Ultra result is the only one below 100 FPS, and the drop from High to Ultra at 4K is similar in percentage to the 1080p and 1440p drops, indicating consistent scaling behavior. The 4K Low result of 164 FPS is notably higher than the 1080p Ultra result of 149.9 FPS, which illustrates that settings have a larger impact than resolution alone.

FAQ

Q: Is the Ryzen 5 4600G bottlenecking the RX 7900 XTX in Downfall?

A: Yes, particularly at lower resolutions. The 1080p Low result (296.3 FPS) is only 13.2% higher than the 1440p Low result (257.3 FPS), which is a smaller gap than expected. At 1080p Ultra (149.9 FPS), the CPU's single-thread performance (Cinebench R23 single-core score of 1919) appears to limit the GPU's ability to push higher frame rates.

Q: How does this combo compare to other tested configurations?

A: It ranks 288th out of 1741 combos, placing it in the top 16.5%. The GPU is at the 85th percentile among all GPUs, while the CPU is at the 75th percentile. The CPU's nearest rivals (Intel Core i3-14100T, i3-13100F) have average scores within 1% of the 4600G, suggesting similar in-game performance.

Q: What is the best resolution for this combo in Downfall?

A: The data shows that 1440p High (172.9 FPS) strikes the best balance between visual quality and frame rate. At 4K High (109.2 FPS), the experience is still smooth, but the 4K Ultra setting (71.2 FPS) approaches the lower boundary of high-refresh-rate gaming.

Q: How does the GPU's memory bandwidth affect performance at 4K?

A: The RX 7900 XTX has 960.0 GB/s of bandwidth across a 384-bit bus, which is substantial. The 4K High result (109.2 FPS) and 4K Medium result (130.5 FPS) indicate that the memory subsystem is not a bottleneck, as the GPU's compute capabilities (61.39 TFLOPS) are more likely the limiting factor at Ultra settings.

Q: Is the integrated Radeon Vega 7 graphics relevant for this game?

A: No, the dedicated RX 7900 XTX handles all rendering. The Vega 7 iGPU is present on the 4600G but is not used when a discrete GPU is installed. The measured FPS values come exclusively from the RX 7900 XTX.

Q: How does the CPU's 8 MB L3 cache impact Downfall performance?

A: The 8 MB shared L3 cache is relatively small by modern standards, but Downfall is not a cache-sensitive title based on the data. The CPU's benchmark scores (Cinebench R23 multi-core of 13593) suggest it provides adequate throughput for the game's logic, though the single-core score of 1919 limits peak frame rates.

Settings Recommendations

The measured data provides clear guidance for the optimal experience in Downfall. At 1920x1080, the High preset (245.5 FPS) is the recommended choice, as it delivers nearly the same performance as Medium (272.9 FPS) while offering better visual fidelity. The Ultra preset (149.9 FPS) is a significant drop and not worth the visual gain at this resolution, given that High already exceeds 240 FPS.

At 2560x1440, the High preset (172.9 FPS) is again the sweet spot. The Medium preset (210.3 FPS) offers a 21.6% performance boost but likely with reduced visual quality, while Ultra (105.9 FPS) drops below 120 FPS, which may be noticeable on high-refresh-rate displays. For players prioritizing smoothness, Medium is viable, but High provides the best balance.

At 3840x2160, the Medium preset (130.5 FPS) is the recommended choice for high-refresh-rate 4K displays. High (109.2 FPS) is still above 100 FPS and acceptable, but Ultra (71.2 FPS) falls below the 75 FPS threshold that many consider the minimum for smooth gameplay. The Low preset (164 FPS) is an option for competitive play but sacrifices too much visual quality for a horror game where atmosphere matters.

Overall, the High preset across all resolutions delivers the most consistent experience, with frame rates ranging from 109.2 FPS at 4K to 245.5 FPS at 1080p. Players with 144 Hz or 165 Hz monitors should target 1440p High for the best combination of visual immersion and frame rate stability, while those with 4K displays can enjoy High or Medium settings without dropping below 100 FPS. The Ultra preset is best reserved for players with VRR displays who prioritize image quality over frame rate, as the 71.2 FPS minimum at 4K Ultra remains playable but noticeably less fluid.
