Downfall

The Intel Core i7-13700K paired with the AMD Radeon RX 6650 XT delivers a highly playable experience in Downfall across most settings, but the data reveals a clear performance ceiling. This combination ranks in the 35th percentile of tested configurations, placing it in the lower-mid tier of the database. The benchmark results indicate a system where the GPU is the primary limiting factor at higher resolutions, while the CPU provides ample headroom to avoid bottlenecks at lower settings.

Resolution Scaling

The measured FPS data shows a predictable decline in performance as resolution increases from 1920x1080 to 3840x2160, but the rate of decline reveals important details about system balance. At High settings, the average frame rate drops from 133 FPS at 1920x1080 to 95 FPS at 2560x1440, representing a 28.6% reduction. Moving from 2560x1440 to 3840x2160 at High settings yields a further drop from 95 FPS to 59 FPS, a 37.9% reduction. This accelerating decline with each resolution step indicates the GPU is becoming progressively more saturated.

The scaling pattern at Low settings is even more revealing. At 1920x1080 Low, the system produces 199 FPS, which falls to 142 FPS at 2560x1440 (a 28.6% drop) and then to 88 FPS at 3840x2160 (a 38.0% drop from 1440p). The fact that even at Low settings the 4K resolution cannot approach the frame rates seen at 1080p suggests that pixel throughput, not shader complexity, is the dominant constraint. The RX 6650 XT’s pixel rate of 168.6 GPixel/s appears to be the ceiling here.

At Medium settings, the system shows a similar trajectory: 162 FPS at 1080p, 116 FPS at 1440p, and 72 FPS at 4K. The min-to-max FPS spread at Medium settings narrows as resolution increases, from a 49 FPS range at 1080p (138-187) to a 22 FPS range at 4K (61-83). This compression of frame time variance at higher resolutions further confirms that the GPU is working near its limit, reducing the impact of CPU-side frame pacing variations.

The Ultra preset demonstrates the steepest scaling curve, with 83 FPS at 1080p falling to 59 FPS at 1440p and finally to 37 FPS at 4K. This 55.4% reduction from 1080p to 4K at Ultra settings is the largest proportional drop across all presets, indicating that the combination of high resolution and maximum graphical features overwhelms the GPU’s 8 GB memory buffer and 128-bit memory bus.

GPU Role

The AMD Radeon RX 6650 XT is the performance bottleneck for this configuration in Downfall, particularly at 4K resolution. The GPU features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. This memory configuration appears adequate for 1080p and 1440p gameplay but becomes strained at 3840x2160, where the Ultra preset drops to 37 FPS average. The GPU’s boost clock of 2635 MHz and game clock of 2410 MHz provide the raw compute capability, but the 10.79 TFLOPS of FP32 performance is insufficient for maximum settings at 4K.

The GPU’s benchmark results place it at the 65th percentile of all GPUs, with an average benchmark score of 19765. Its nearest rivals in the database include the NVIDIA Tesla K40m (0.6% faster), AMD FirePro D300 (0.7% slower), AMD FirePro W7000 (0.7% faster), and NVIDIA Quadro K5200 (0.8% slower). These are all professional or workstation-class cards, which suggests the RX 6650 XT’s gaming performance is competitive with older high-end compute hardware but not with modern flagship gaming GPUs.

The observed FPS data supports the conclusion that the GPU is the limiting component. At 1920x1080 Low, the system achieves 199 FPS, which is likely near the CPU’s capable frame delivery limit. However, increasing resolution to 4K Low drops performance to 88 FPS, a 55.8% reduction, despite the graphics workload being identical in terms of scene complexity. This is a classic sign of GPU-bound rendering, where the fill rate and memory bandwidth of the RX 6650 XT cannot keep pace with the increased pixel count.

The 4K Ultra result of 37 FPS is particularly telling. This is below the 60 FPS threshold commonly considered smooth for action games, and the 8 GB VRAM capacity may be insufficient for Ultra textures at this resolution. The GPU’s 64 ROPs and 128 TMUs are likely saturated, and the 280.3 GB/s memory bandwidth becomes a severe constraint when handling 4K Ultra assets.

CPU Role

The Intel Core i7-13700K provides substantial processing headroom for Downfall, a game that does not appear to be heavily multi-threaded based on the FPS data. The CPU features 16 cores and 24 threads, with a base clock of 3.40 GHz and a boost clock of 5.40 GHz. This Raptor Lake architecture with 30 MB of shared L3 cache delivers exceptional single-threaded performance, as evidenced by its 3DMark single-thread score of 1136 and Cinebench R23 single-core score of 2116.

The CPU’s benchmark results place it at the 89th percentile of all CPUs, with an average benchmark score of 46881. Its nearest rivals include the AMD Ryzen 9 5900 (0.2% slower), AMD Ryzen AI 9 HX PRO 375 (0.3% slower), AMD Ryzen 9 7845HX (0.5% faster), and Intel Xeon w3-2535 (0.5% faster). This places the i7-13700K in a tightly contested performance band where differences of less than 1% separate competing processors.

In Downfall, the CPU’s role appears secondary to the GPU at all tested resolutions. The fact that FPS scales down significantly with resolution at Low settings—from 199 FPS at 1080p to 88 FPS at 4K—indicates that even the CPU’s 3DMark max-thread score of 12412 is not the limiting factor. If the CPU were the bottleneck, the FPS would remain relatively constant across resolutions as long as the graphics settings are low enough to avoid GPU saturation.

The CPU’s single-threaded performance is likely more relevant for this game. The 3DMark 2-thread score of 2262 and 4-thread score of 4469 suggest strong performance on lightly-threaded workloads, which is typical for horror games that may have simpler AI and physics systems. The boost clock of 5.40 GHz provides the high frequency needed for such workloads, and the 125 W TDP indicates the CPU can sustain this performance without excessive thermal throttling.

The combination of high single-thread performance and 16 cores means the CPU is unlikely to cause frame drops or stutters in Downfall, even when the GPU is stressed at 4K. The benchmark data supports this, as the min FPS values at Medium settings (61 FPS at 4K, 99 FPS at 1440p, 138 FPS at 1080p) are all within reasonable range of the average FPS, suggesting consistent frame delivery without CPU-induced hitches.

How This Combo Ranks

This specific combination of Intel Core i7-13700K and AMD Radeon RX 6650 XT ranks 2424 out of 3716 tested combos in Downfall, placing it in the 34.8th percentile of all configurations. This is a relatively low ranking, indicating that there are many more capable combinations in the database for achieving high frame rates in this game. The ranking reflects the GPU’s 65th percentile performance combined with the CPU’s 89th percentile performance, resulting in a system that is held back by its graphics component.

The gap between the CPU and GPU percentiles is notable. The i7-13700K is clearly a high-end processor, sitting in the top 11% of all CPUs, while the RX 6650 XT is a mid-range GPU in the top 35% of all GPUs. This imbalance suggests that the CPU is overqualified for the GPU in this pairing, at least for Downfall. The measured FPS data confirms this, as the system cannot achieve high frame rates at 4K regardless of settings, despite the CPU’s ability to handle far more complex workloads.

Compared to other combos in the database, this pairing is positioned near the lower-mid range. The 2424th rank out of 3716 means that roughly two-thirds of tested combinations outperform it in Downfall. This is consistent with the GPU’s performance class—the RX 6650 XT is not designed for high-refresh-rate 4K gaming, and the data shows it struggles to maintain 60 FPS at 4K even at Medium settings (72 FPS average) and falls well below at Ultra (37 FPS).

The combo’s ranking is likely influenced by the game’s specific requirements. Downfall, being a horror game from 2016, may not be heavily optimized for modern hardware, but it also does not appear to be exceptionally demanding. The fact that this combo achieves 199 FPS at 1080p Low suggests the game is not particularly taxing on the CPU, which means the GPU is the sole determinant of performance in most scenarios.

FAQ

Q: Does the 8 GB VRAM affect 4K performance?

A: The 4K Ultra preset achieves only 37 FPS average, which is likely influenced by the 8 GB GDDR6 memory capacity and 280.3 GB/s bandwidth. The 128-bit memory bus may not provide sufficient bandwidth for Ultra-quality textures at 3840x2160, contributing to the significant FPS drop from Medium (72 FPS) to Ultra (37 FPS).

Q: How does this combo compare to the CPU’s rival configurations?

A: The i7-13700K’s nearest rivals (AMD Ryzen 9 5900, AMD Ryzen AI 9 HX PRO 375, AMD Ryzen 9 7845HX, Intel Xeon w3-2535) all have average benchmark scores within 0.5% of this CPU. Since the GPU is the bottleneck, pairing any of those CPUs with the RX 6650 XT would likely produce similar FPS results in Downfall.

Settings Recommendations

The optimal settings for this combo depend on the target resolution and desired frame rate. At 1920x1080, all presets deliver playable frame rates, with High (133 FPS) and Medium (162 FPS) offering the best balance of visual quality and performance. The Ultra preset at 83 FPS is also viable for those prioritizing visual fidelity, though the 49 FPS gap between Medium and Ultra suggests diminishing returns.

For 2560x1440, High settings at 95 FPS is the recommended choice for most users, as it provides a comfortable margin above 60 FPS while maintaining good visual quality. Medium at 116 FPS offers additional headroom for competitive play, while Ultra at 59 FPS is borderline and may exhibit occasional dips below the 60 FPS threshold. Low at 142 FPS is excessive for this resolution and sacrifices too much visual quality.

At 3840x2160, the choices are more constrained. Medium settings at 72 FPS is the best option for maintaining smooth gameplay, with a min FPS of 61 that stays above the 60 FPS line. Low at 88 FPS is also viable but visually degraded. High at 59 FPS is marginal, and Ultra at 37 FPS is not recommended for consistent playability. The data suggests that 4K users should stick to Medium or Low presets with this GPU.

The measured FPS range at Medium settings across all resolutions—from 162 FPS at 1080p to 72 FPS at 4K—indicates this preset provides the most consistent performance scaling. For users with variable resolution displays, Medium offers the safest default. At 1080p, High is the sweet spot; at 1440p, High or Medium both work well; at 4K, only Medium or Low should be considered.

Measured FPS Breakdown

The following are the exact measured average FPS values from the FACT PACK data, organized by resolution and settings:

1920x1080:

• Low: 199 FPS average
• Medium: 162 FPS average, with min FPS of 138 and max FPS of 187
• High: 133 FPS average
• Ultra: 83 FPS average

2560x1440:

• Low: 142 FPS average
• Medium: 116 FPS average, with min FPS of 99 and max FPS of 133
• High: 95 FPS average
• Ultra: 59 FPS average

3840x2160:

• Low: 88 FPS average
• Medium: 72 FPS average, with min FPS of 61 and max FPS of 83
• High: 59 FPS average
• Ultra: 37 FPS average

The min and max FPS values are only available for Medium settings, which show a consistent pattern of frame time variance. At 1080p Medium, the range between min and max is 49 FPS, indicating some CPU or driver overhead. At 1440p Medium, the range narrows to 34 FPS, and at 4K Medium, it further narrows to 22 FPS. This tightening of variance at higher resolutions is consistent with GPU saturation, where the GPU is so heavily loaded that frame times become more uniform.

The data shows that the combo achieves its best performance at 1080p Low with 199 FPS, which is likely close to the game’s engine limits or VSync cap. The step from Low to Medium at 1080p costs 37 FPS, while the step from Medium to High costs 29 FPS, and from High to Ultra costs 50 FPS. This non-linear scaling suggests that Ultra settings introduce disproportionately expensive effects that heavily tax the RX 6650 XT’s 10.79 TFLOPS compute capability.

At 4K, the performance envelope is much narrower: from 37 FPS at Ultra to 88 FPS at Low, a 51 FPS spread across all presets. This compressed range reinforces the conclusion that the GPU is the absolute bottleneck at this resolution, with no amount of CPU headroom able to compensate for the pixel throughput demands of 3840x2160.
