Downfall

# Downfall with Intel Core Ultra 7 265K + AMD Radeon RX 6600

The pairing of Intel's Core Ultra 7 265K with AMD's Radeon RX 6600 produces a decidedly GPU-bound experience in Downfall, a 2016 horror title. Across all measured resolutions, the frame rate scales predictably with pixel count and settings, with the Radeon RX 6600's 8 GB frame buffer and 224.0 GB/s memory bandwidth acting as the primary constraint. The Intel Core Ultra 7 265K, with its 20 cores and 20 threads boosting to 5.50 GHz, never appears to bottleneck the GPU, as evidenced by the smooth progression of scores from 1080p through 4K. The combination ranks 1430 out of 1741 tested combos in this game, placing it in the lower-mid tier of system configurations, which aligns with the RX 6600's 69th percentile standing among all GPUs versus the CPU's 97th percentile among all processors.

Resolution Scaling

The measured FPS data reveals a clear and consistent pattern of degradation as resolution increases, characteristic of a GPU-limited scenario. At 1080p High settings, the system delivers 115.6 FPS average; moving to 1440p High drops performance to 85.4 FPS, a reduction of approximately 26%, and then to 4K High, the average falls further to 49.7 FPS, representing a 57% loss from the 1080p baseline. This scaling curve is steep and predictable, indicating that the Radeon RX 6600's compute resources — 1792 shading units, 112 TMUs, and 64 ROPs — are being saturated as pixel throughput demands increase. The 4K High result of 49.7 FPS sits just below the 60 FPS threshold, while 1440p High maintains playable performance, and 1080p High remains smooth.

The Low settings preset tells a similar story with higher absolute numbers. At 1080p Low, the combo reaches 173.1 FPS average, while 1440p Low yields 122.6 FPS (a 29% drop), and 4K Low delivers 78.8 FPS (a 54% drop from 1080p). The fact that even at Low settings, the 4K resolution still caps below 80 FPS suggests that the GPU's raw fillrate and bandwidth — 159.4 GPixel/s pixel rate and 224.0 GB/s memory bandwidth — are the limiting factors, not the CPU's processing capability. The Intel Core Ultra 7 265K, with its 30 MB of L3 cache and DDR5 memory support at 102.4 GB/s bandwidth, has ample headroom to feed the GPU at all tested resolutions.

When examining the Ultra preset, the scaling becomes even more pronounced: 72.3 FPS at 1080p, 52.8 FPS at 1440p (a 27% reduction), and 34.5 FPS at 4K (a 52% reduction from 1080p). This Ultra preset, which likely increases shadow quality, texture detail, and post-processing effects, pushes the RX 6600 beyond its comfort zone at higher resolutions. The 4K Ultra result of 34.5 FPS is the only sub-40 FPS measurement in the entire dataset, underscoring that this combination is not intended for maximum fidelity at 4K. The data indicates that the limiting component is unequivocally the GPU across all resolution and settings combinations, as the CPU's benchmark scores (Cinebench R23 multi-core of 50009 and single-core of 7060) place it in the top 3% of all processors, far exceeding what Downfall's 2016 engine requires.

GPU Role

The AMD Radeon RX 6600 serves as the definitive performance ceiling in this configuration. With 8 GB of GDDR6 memory on a 128-bit bus, the card offers 224.0 GB/s of bandwidth, which proves adequate for 1080p and 1440p gaming but becomes strained at 4K, particularly with higher quality settings. The GPU's clock behavior — a base of 1626 MHz, game clock of 2044 MHz, and boost up to 2491 MHz — shows that the card is operating near its designed frequency envelope during these benchmarks. The RDNA 2.0 architecture, built on TSMC's 7 nm process with 11,060 million transistors, delivers 8.928 TFLOPS of FP32 performance, which is modest by modern standards but sufficient for a horror title from 2016.

The VRAM capacity of 8 GB is a critical factor in the Ultra preset results. At 4K Ultra, the average FPS collapses to 34.5, a 30% drop from the 4K High result of 49.7 FPS. This disproportionate penalty suggests that the Ultra preset may be exceeding the 8 GB frame buffer capacity, forcing the GPU to manage memory more aggressively. In contrast, the 1080p Ultra result of 72.3 FPS is only 37% below the 1080p High score, indicating that at lower resolutions, the VRAM pressure is less severe. The GPU's 69th percentile ranking among all GPUs, with an average benchmark score of 25235, places it in the mid-range tier, closely matching the AMD Radeon 890M (25246, 0% delta) and AMD Radeon RX 580 2048SP (25287, -0.2% delta), which confirms its position as a capable but not high-end solution.

The RX 6600's nearest rival, the NVIDIA GeForce RTX 3060 Ti, shows a delta of only 0.5% in average benchmark score, yet the RTX 3060 Ti typically offers superior ray tracing performance. However, in Downfall, a 2016 title that predates mainstream ray tracing, the RX 6600's 28 ray accelerators are largely irrelevant. The GPU's DirectX 12 Ultimate support (12_2) ensures compatibility with modern APIs, but the game's age means it likely relies on DirectX 11, where the RX 6600's Passmark DirectX 11 score of 152 demonstrates solid legacy performance. The 132 W TDP and dual-slot design with a single 8-pin connector indicate an efficient card that operates within predictable thermal and power envelopes.

FAQ

Q: Is the Intel Core Ultra 7 265K bottlenecking the Radeon RX 6600 in Downfall?

A: No. The data indicates the GPU is the limiting factor at all resolutions. At 1080p Low, the system achieves 173.1 FPS, and even at 4K Ultra, the frame rate of 34.5 FPS is consistent with GPU-bound behavior. The CPU's 97th percentile ranking among all processors, with a Cinebench R23 multi-core score of 50009, vastly exceeds the requirements of a 2016 horror game, leaving no evidence of CPU limitation.

Q: How does the RX 6600 compare to its nearest rivals in this game?

A: The RX 6600's average benchmark score of 25235 is essentially identical to the AMD Radeon 890M (25246, 0% delta) and the AMD Radeon RX 580 2048SP (25287, -0.2% delta). The NVIDIA GeForce RTX 3060 Ti scores 25120, which is 0.5% lower. These near-identical scores suggest that in Downfall, performance differences among these GPUs would be minimal, with the RX 6600's 8 GB VRAM and 224.0 GB/s bandwidth providing adequate resources.

Q: What is the best settings/resolution combination for smooth gameplay?

A: At 1080p High, the system delivers 115.6 FPS, which is comfortably above the 60 FPS threshold. For 1440p, High settings produce 85.4 FPS, also smooth. At 4K, only Low settings (78.8 FPS) and Medium settings (63.2 FPS) maintain playable frame rates. For a 60 FPS target, 1440p High or 4K Medium are the optimal choices.

Q: Why does the Ultra preset cause such a large performance drop at 4K?

A: The 4K Ultra result of 34.5 FPS represents a 30% drop from 4K High (49.7 FPS). This disproportionate penalty is likely due to the 8 GB VRAM capacity being exceeded at that combination, forcing the GPU to handle memory pressure. The RX 6600's 128-bit memory interface and 224.0 GB/s bandwidth struggle to maintain throughput when texture and effect quality are maximized at 4K.

Q: How does this combo rank among all tested configurations?

A: The combination of Intel Core Ultra 7 265K and AMD Radeon RX 6600 ranks 1430 out of 1741 tested combos in Downfall. This places it in the lower 18% of configurations, which is expected given that the GPU is a mid-range part (69th percentile) while the CPU is a high-end part (97th percentile). The pairing is unbalanced, with the GPU being the clear performance limiter.

Q: Does the CPU's performance affect the frame rates in this game?

A: The data shows no evidence of CPU influence. At 1080p Low, the system reaches 173.1 FPS, which approaches the refresh rate limits of many displays. The CPU's single-thread performance (Cinebench R23 single-core of 7060) and multi-thread capability (50009) are far beyond what a 2016 horror title demands. The consistent frame rate drops across resolutions — 26-29% from 1080p to 1440p and 52-57% from 1080p to 4K — are textbook GPU scaling patterns.

Measured FPS Breakdown

At 1080p resolution, the Radeon RX 6600 delivers its strongest results. Low settings produce the highest average at 173.1 FPS, followed by Medium at 141.2 FPS, High at 115.6 FPS, and Ultra at 72.3 FPS. The spread between Low and Ultra is 100.8 FPS, representing a 58% performance reduction when all quality features are enabled. This range demonstrates that the GPU has substantial headroom at 1080p, with even the most demanding preset remaining above 70 FPS.

At 1440p, the performance tier shifts downward noticeably. Low settings achieve 122.6 FPS average, Medium delivers 101 FPS, High drops to 85.4 FPS, and Ultra falls to 52.8 FPS. The gap between Low and Ultra narrows to 69.8 FPS (a 57% reduction), but the absolute numbers remain playable for most presets. The 1440p Ultra result of 52.8 FPS is the first instance where a preset falls below 60 FPS, indicating that users targeting 1440p should stick to High or below for consistent smoothness.

At 4K, the GPU's limitations become fully apparent. Low settings yield 78.8 FPS average, Medium produces 63.2 FPS, High drops to 49.7 FPS, and Ultra collapses to 34.5 FPS. The delta between Low and Ultra at 4K is 44.3 FPS (a 56% reduction), but the absolute performance levels are insufficient for high-fidelity gaming. Only Low and Medium presets maintain 60 FPS or above at 4K, and even then, Medium barely clears the threshold at 63.2 FPS. This resolution scaling demonstrates that the RX 6600 is best suited for 1080p gaming, capable at 1440p with moderate settings, and marginal at 4K with reduced quality.

How This Combo Ranks

The combination of Intel Core Ultra 7 265K and AMD Radeon RX 6600 achieves a rank of 1430 out of 1741 tested combinations in Downfall, placing it in the 18th percentile of all configurations. This ranking is primarily driven by the GPU's performance class, as the CPU is a top-tier component. The RX 6600's 69th percentile among all GPUs, with an average benchmark score of 25235, is the limiting factor in this pairing. The CPU's 97th percentile ranking, with an average benchmark score of 79102, provides a stark contrast — the system is built around a high-end processor paired with a mid-range graphics card.

The nearest GPU rivals confirm this positioning. The AMD Radeon 890M (25246, 0% delta), AMD Radeon RX 580 2048SP (25287, -0.2% delta), and AMD Radeon RX 6700M (25180, 0.2% delta) all achieve nearly identical average benchmark scores, suggesting that in Downfall, these GPUs would produce similar frame rates. The NVIDIA GeForce RTX 3060 Ti (25120, 0.5% delta) is also within 0.5% of the RX 6600's score. This clustering of mid-range GPUs around the 25,000 score mark indicates that the RX 6600 is representative of a broad performance tier, and its 1430 rank in Downfall reflects this mid-pack positioning.

The CPU's nearest rivals — Intel Core Ultra 7 265KF (79240, -0.2% delta), Intel Core i9-14900KF (79245, -0.2% delta), and Intel Core i9-14900K (79824, -0.9% delta) — all perform within 1% of the Core Ultra 7 265K's average score of 79102. This means that swapping the CPU for any of these alternatives would have virtually no impact on Downfall performance, since the GPU is the bottleneck in every scenario tested. The ranking of 1430 out of 1741 is therefore a GPU-driven result, not a reflection of CPU capability. For users seeking higher rankings in this game, upgrading the graphics card would yield far more significant gains than changing the processor, as the data clearly shows the RX 6600 as the performance ceiling across all resolutions and settings.
