Downfall

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-12700KF is a 12-core, 20-thread desktop processor based on the Alder Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a 25 MB shared L3 cache. This processor ranks in the 89th percentile among all CPUs, with an average benchmark score of 35355, placing it nearly identical to rivals like the Intel Core i5-14400 (0.1% faster) and the Intel Core i7-13800H (0.2% slower).

In the context of Downfall, a horror game released in 2016, the CPU's multi-threaded capacity is substantial but not the limiting factor. The 3dmark_max_threads score of 9983 and the Cinebench R23 multi-core score of 28979 show strong throughput, but the game's performance at 1080p Low (89.7 FPS) versus 1080p High (62.9 FPS) indicates that graphical settings, not CPU compute, dominate the frame rate differences. The single-thread performance — a 3dmark_single_thread score of 1043 and a Passmark single-thread score of 3984 — is sufficient to feed the GPU at lower resolutions, as evidenced by the 1080p Low result exceeding 60 FPS. The CPU's 20 threads and 12 cores are far beyond what a 2016 horror title typically requires; the bottleneck clearly shifts to the GPU as resolution and settings increase.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 570 uses the Polaris 20 chip on a 14 nm process, with 2048 shading units, 128 texture mapping units, and 32 raster output units. It carries 4 GB of GDDR5 memory on a 256-bit bus, yielding a bandwidth of 224.0 GB/s. The GPU's base clock is 1168 MHz with a boost of 1244 MHz, and its memory runs at 1750 MHz (7 Gbps effective). This card achieves 5.095 TFLOPS of FP32 performance and sits in the 74th percentile among all GPUs, with an average benchmark score of 30158.

The RX 570's nearest rivals in aggregate benchmark scores are surprising: the NVIDIA GeForce RTX 5060 (0.2% higher), the AMD Radeon RX 7700 XT (0.2% higher), and the NVIDIA Tesla M60 (0.6% higher). However, in Downfall specifically, the 4 GB VRAM capacity becomes a critical constraint at higher settings. At 4K Ultra, the combination drops to 14.7 FPS, while 4K High manages 25.9 FPS — a clear sign that the GPU's memory bandwidth and capacity are overwhelmed. The 224.0 GB/s bandwidth is adequate for 1080p gaming, but at 4K, the texture and shading demands outstrip what the Polaris architecture can deliver. The GPU's 74th percentile ranking does not translate to playable 4K performance in this title at Ultra settings, underscoring that this card is best suited for 1080p or modest 1440p gaming.

FAQ

Q: What is the best resolution to play Downfall with this combo for a smooth experience?

A: At 1080p with Low settings, the average FPS is 89.7, which is the highest measured result across all resolutions and settings. Even at 1080p High, the average is 62.9 FPS, which remains playable. At 1440p, only Low settings (63.3 FPS) exceed the 60 FPS threshold, while High dips to 44.7 FPS.

Q: How does the CPU compare to its nearest rivals in raw performance?

A: The i7-12700KF has an average benchmark score of 35355, which is 0.1% higher than the Intel Core i5-14400 (35336), 0.2% lower than the Intel Core i7-13800H (35416), and 0.2% higher than the Intel Core i9-12900HX (35289). These differences are negligible in practice.

Q: Is the RX 570's 4 GB VRAM sufficient for Ultra settings in Downfall?

A: No. At 4K Ultra, the average FPS drops to 14.7, and at 1440p Ultra it is 30.3 FPS. Even at 1080p Ultra, the average is 41.8 FPS, which is below the 60 FPS target. The 4 GB GDDR5 memory appears to be a limiting factor at Ultra presets across all resolutions.

Q: What is the frame rate drop from 1080p Low to 4K Low?

A: The average FPS falls from 89.7 at 1080p Low to 39.1 at 4K Low, representing a 56.4% reduction. This substantial drop indicates that the GPU is the primary constraint, as the CPU's performance is unchanged across resolutions.

Q: How does the combo rank among all tested combinations in Downfall?

A: This specific configuration ranks 1673 out of 1741 tested combos, placing it in the bottom 4% of all tested systems. This low ranking is driven by the GPU's inability to handle higher resolutions and settings, not the CPU.

Q: What settings should be used at 1440p to maintain a playable frame rate?

A: Only Low settings at 1440p provide an average above 60 FPS (63.3 FPS). Medium settings drop to 56.0 FPS, which is borderline playable, but High (44.7 FPS) and Ultra (30.3 FPS) are not recommended for smooth gameplay.

Measured FPS Breakdown

The measured data provides a complete picture across three resolutions and four settings presets. At 1920x1080, the performance scales predictably: Low averages 89.7 FPS, Medium 74.1 FPS, High 62.9 FPS, and Ultra 41.8 FPS. The gap between Low and Ultra is 47.9 FPS, indicating that the GPU is heavily taxed by the Ultra preset's demands.

Moving to 2560x1440, the frame rates drop significantly. Low averages 63.3 FPS, Medium 56.0 FPS, High 44.7 FPS, and Ultra 30.3 FPS. The drop from 1080p to 1440p at the same settings is notable: Low falls by 26.4 FPS, Medium by 18.1 FPS, High by 18.2 FPS, and Ultra by 11.5 FPS. The smaller absolute drop at Ultra suggests that the GPU is already saturated at 1080p Ultra, and additional resolution has diminishing impact.

At 3840x2160, the results become largely unplayable. Low averages 39.1 FPS, Medium 33.8 FPS, High 25.9 FPS, and Ultra 14.7 FPS. The Ultra preset at 4K is the worst measured result, with a frame rate that is less than one-sixth of the 1080p Low result. The data shows a clear pattern: the RX 570 delivers playable performance only at 1080p (all settings except Ultra) and 1440p Low. Every 4K setting falls below 40 FPS, and Ultra at any resolution below 1080p is not tested but would likely be worse than the 41.8 FPS seen at 1080p Ultra.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals the GPU as the dominant bottleneck. At Low settings, the average FPS drops from 89.7 at 1080p to 63.3 at 1440p and 39.1 at 4K. This represents a 29.4% drop from 1080p to 1440p and a 56.4% drop from 1080p to 4K. The scaling is nearly linear with pixel count — 1440p has 1.78 times the pixels of 1080p, and 4K has 4 times the pixels — which is characteristic of a GPU-bound scenario.

At High settings, the scaling is steeper: 62.9 FPS at 1080p, 44.7 FPS at 1440p, and 25.9 FPS at 4K. The percentage drops are 28.9% and 58.8% respectively. At Ultra settings, the pattern holds: 41.8 FPS at 1080p, 30.3 FPS at 1440p, and 14.7 FPS at 4K, with drops of 27.5% and 64.8%. The fact that the CPU's 3dmark_max_threads score of 9983 and single-thread score of 1043 remain constant across all resolutions confirms that the i7-12700KF is not the limiting component. The GPU's 224.0 GB/s memory bandwidth and 4 GB VRAM are the constraining factors, as the frame rate drops align with the increased memory and fill-rate demands of higher resolutions.

Settings Recommendations

For this combination in Downfall, the optimal settings depend on the target resolution and frame rate priority. At 1080p, Low settings deliver the highest average FPS at 89.7, which is well above the 60 FPS threshold. Medium settings at 74.1 FPS also provide a smooth experience, and High at 62.9 FPS is still playable. Ultra at 41.8 FPS is the only 1080p preset that fails to reach 60 FPS, so it should be avoided unless visual fidelity is paramount.

At 1440p, only Low settings (63.3 FPS) reliably exceed 60 FPS. Medium at 56.0 FPS is close but may exhibit occasional stutter in a horror game where timing matters. High (44.7 FPS) and Ultra (30.3 FPS) are not recommended for a responsive experience. At 4K, all settings fall below 40 FPS, making this resolution impractical for playable frame rates with the RX 570.

The best experience per the measured rows is achieved at 1080p with Medium settings: 74.1 FPS provides a comfortable margin above 60 FPS while offering better visual quality than Low. For players prioritizing maximum smoothness, 1080p Low at 89.7 FPS is the top choice. The data suggests that the 4 GB VRAM ceiling makes Ultra presets unusable at any resolution above 1080p, and even at 1080p, the 41.8 FPS result is below the playability threshold. A capable air cooler for the CPU is sufficient given the 125 W TDP, but the GPU's 150 W TDP and 450 W suggested PSU should be respected.

How This Combo Ranks

This specific combination of the Intel Core i7-12700KF and AMD Radeon RX 570 ranks 1673 out of 1741 tested combos in Downfall, placing it in the bottom 4% of all configurations. This low ranking is striking given the individual component percentiles: the CPU sits in the 89th percentile among all CPUs, while the GPU is in the 74th percentile. The discrepancy highlights a severe imbalance — the CPU is a high-end processor from 2021, while the GPU is an end-of-life product from 2017.

The benchmark results confirm this mismatch. The CPU's Cinebench R23 multi-core score of 28979 and Passmark multi-thread score of 34092 indicate a processor capable of handling demanding workloads, yet the GPU's 4 GB VRAM and 5.095 TFLOPS of FP32 performance cannot translate that CPU power into playable frame rates at higher settings. The combo's rank of 1673 means that 68 tested combinations perform worse, but the vast majority of tested systems outperform it. The data suggests that pairing a top-tier CPU with a mid-range GPU from an older generation creates a bottleneck that no amount of CPU headroom can overcome. For Downfall specifically, the GPU is the sole determinant of playability, and the RX 570's limitations at 1440p and 4K cap this combo's potential. The 1080p results are respectable, but the overall ranking reflects the system's inability to handle modern resolutions and presets.
