Downfall

The pairing of Intel’s 24-core Core Ultra 7 270K Plus with AMD’s Radeon RX 580 creates a stark imbalance in Downfall. The data shows a processor capable of dominating workstation tasks paired with a graphics card whose benchmark percentile sits at 53, meaning it is outclassed by nearly half of all GPUs. This dynamic dictates every performance figure, making the RX 580 the definitive bottleneck across all tested resolutions.

Resolution Scaling

The measured FPS data reveals a classic pattern of GPU-limited scaling. At 1080p with Low settings, the combo achieves an average of 102 FPS. Moving to 1440p Low reduces that to 73 FPS, a drop of 29 FPS. At 4K Low, the average falls further to 45 FPS. This steep decline with increasing pixel count is the signature of a graphics card operating at its absolute limit, as the CPU has ample headroom to feed frames far faster than the GPU can render them.

The scaling becomes more dramatic when examining the High preset. The 1080p High average of 68 FPS drops to 49 FPS at 1440p High, a 19 FPS reduction. At 4K High, the average plummets to 30 FPS. The percentage loss from 1080p to 4K at High settings is roughly 56%, indicating that the render resolution is the primary factor limiting performance. The CPU’s core count and clock speed are largely irrelevant in this scenario because the GPU cannot translate that processing power into additional frames.

This behavior is consistent across all quality presets. The gap between 1080p and 4K at Medium settings is 46 FPS (83 vs 37), while at Ultra settings the gap is 24 FPS (43 vs 19). These consistent deltas suggest that the RX 580’s memory bandwidth and fill rate are the constraining factors. The 256-bit bus and 256.0 GB/s bandwidth simply cannot sustain high frame rates as the pixel workload increases quadratically with resolution. The data implies that users seeking higher resolutions must accept significant compromises in graphical fidelity to maintain playable frame rates.

GPU Role

The Radeon RX 580’s specifications directly explain its performance ceiling. With 8 GB of GDDR5 memory operating at 2000 MHz (8 Gbps effective), the card has sufficient capacity for most scenes but struggles with throughput at high resolutions. The 2304 shading units and 32 ROPs are dated by modern standards, and the 6.175 TFLOPS FP32 compute figure places it firmly in the entry-level segment of the current market.

The clock speeds of 1257 MHz base and 1340 MHz boost are modest, and the data shows that these clocks do not scale well with increased load. The 3DMark Steel Nomad DX12 score of 1005 and Passmark G3D score of 8813 reinforce the card’s position in the 53rd percentile. When placed against its nearest rivals, the RX 580 trails the GeForce GTX 1660 SUPER by 0.4% in average benchmark score, highlighting how close it is to the bottom of the modern GPU hierarchy.

The VRAM configuration becomes a critical factor at 4K. The 8 GB capacity is adequate, but the effective memory bandwidth of 256.0 GB/s is insufficient for the data throughput required at 3840x2160. This explains why the 4K Ultra preset averages only 19 FPS, a figure that is nearly unplayable. The card’s pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s are simply overwhelmed by the pixel shader complexity of Downfall at high settings. The data suggests that the GPU’s memory subsystem, not its compute capabilities, is the primary limiting factor, as evidenced by the disproportionate FPS drops when resolution increases.

Settings Recommendations

The measured rows provide clear guidance for optimizing the experience. At 1080p, the Low preset delivers the highest average at 102 FPS, but this comes at the cost of visual quality. The Medium preset offers a balanced 83 FPS average, with a minimum of 71 FPS, ensuring smooth gameplay while maintaining some graphical fidelity. The High preset at 68 FPS remains playable, but the Ultra preset at 43 FPS introduces noticeable stutter potential.

For 1440p, the data shows that Medium is the optimal choice. The 60 FPS average with a 51 FPS minimum provides a consistent experience. The High preset at 49 FPS is borderline, while Low at 73 FPS sacrifices too much detail for a marginal gain over Medium. Ultra at 31 FPS is not recommended due to the risk of frame pacing issues.

At 4K, the situation becomes challenging. The Low preset at 45 FPS is the only viable option for any semblance of smoothness. Medium at 37 FPS is playable but demanding, while High at 30 FPS sits right at the edge of acceptability. Ultra at 19 FPS is effectively a slideshow and should be avoided. The data implies that users with 4K displays should either accept Low settings or consider upgrading the GPU, as the RX 580 cannot handle the resolution with higher quality presets.

CPU Role

The Intel Core Ultra 7 270K Plus is a computational powerhouse that is severely underutilized in this gaming scenario. Its 24 cores and 24 threads, combined with a boost clock of 5.50 GHz, produce benchmark scores that place it in the 96th percentile of all CPUs. The Cinebench R23 multicore score of 44253 and single-core score of 2439 demonstrate exceptional processing capability. However, the measured FPS data shows no evidence of CPU bottlenecking at any resolution or settings level.

The CPU’s performance in this game is irrelevant because the RX 580 cannot generate enough frames to stress the processor. The Passmark multithread score of 68574 and single-thread score of 5068 indicate that the CPU could easily handle frame generation far beyond the GPU’s capabilities. The L3 cache of 36 MB and memory bandwidth of 115.2 GB/s provide ample headroom for game logic and asset streaming, but these resources remain largely idle.

The CPU’s nearest rivals include the Intel Xeon 6520P with a deltaPct of 0, the AMD EPYC 4564P at -1.5%, and the AMD EPYC 9175F at -1.9%. These comparisons show that the Core Ultra 7 270K Plus is competitive with high-end server processors, yet in Downfall, its performance is capped by the graphics card. The data suggests that users could pair this CPU with a far more powerful GPU without any risk of CPU-induced frame drops, as the processor’s capabilities far exceed the demands of this horror title.

Measured FPS Breakdown

The complete dataset provides a comprehensive view of performance across all combinations. At 3840x2160, the Ultra preset averages 19 FPS, the High preset averages 30 FPS, the Medium preset averages 37 FPS with a minimum of 32 and maximum of 43, and the Low preset averages 45 FPS. These figures illustrate a linear progression where each step down in quality yields roughly 8-10 FPS improvement.

At 2560x1440, the Ultra preset averages 31 FPS, High averages 49 FPS, Medium averages 60 FPS with a minimum of 51 and maximum of 69, and Low averages 73 FPS. The scaling here is more pronounced, with a 14 FPS jump from Ultra to High and an 11 FPS jump from High to Medium. The Low preset represents a 13 FPS improvement over Medium, indicating that the GPU is less constrained at this resolution.

At 1920x1080, the Ultra preset averages 43 FPS, High averages 68 FPS, Medium averages 83 FPS with a minimum of 71 and maximum of 96, and Low averages 102 FPS. The 1080p results show the most dramatic scaling, with a 25 FPS difference between Ultra and High, and a 19 FPS difference between Medium and Low. The 102 FPS Low figure is the only average above 100 FPS in the entire dataset, confirming that the RX 580 is best suited for 1080p gaming at lower settings.

How This Combo Ranks

The combo ranks 2670 out of 2928 tested combinations in Downfall, placing it in the bottom 9% of all systems. This ranking is unsurprising given the GPU’s 53rd percentile position and the game’s graphical demands. The rank suggests that most other combinations, even those with older or less capable CPUs, outperform this pairing because they likely feature more balanced GPU performance.

The ranking implies that the Core Ultra 7 270K Plus is wasted in this configuration for this specific game. The CPU’s 96th percentile standing is completely negated by the GPU’s mid-pack performance. The delta between the CPU’s high percentile and the combo’s low rank highlights the importance of GPU selection in gaming builds. The data indicates that a user would achieve a better rank by pairing a weaker CPU with a stronger GPU, as the game is entirely GPU-bound.

The 2670th position out of 2928 combos means that 258 other tested systems performed worse, likely featuring even older or lower-end GPUs. However, the vast majority of combinations (over 91%) outperform this setup. This rank serves as a cautionary tale about pairing a high-end processor with an entry-level graphics card, as the overall gaming experience is dictated by the weakest link. For Downfall, the RX 580 is that weak link, and the data clearly shows that no amount of CPU power can compensate for its limitations.
