Downfall

The Intel Core Ultra 7 265K paired with the AMD Radeon RX 6750 XT is a balanced mid-range combination for playing Downfall. The data shows a system that can handle 1080p and 1440p with high refresh rates, but which begins to struggle at 4K with maximum settings. This analysis breaks down the measured performance to show exactly where this combo excels and where its limits are.

Resolution Scaling

The performance drop from 1080p to 4K is the clearest indicator of where the bottleneck lies in this system. At Low settings, the average frame rate falls from 240 FPS at 1920x1080 to 172 FPS at 2560x1440, a reduction of 28.3%. Moving to 3840x2160, the average drops further to 107 FPS, which is a 55.4% decrease from the 1080p result. This scaling pattern is typical for a GPU-bound scenario, but the absolute numbers remain high enough to suggest the CPU is still feeding frames adequately.

The High settings preset tells a similar story. The average FPS at 1080p is 161, which drops to 115 at 1440p (a 28.6% reduction) and then to 72 at 4K (a 55.3% reduction from 1080p). The consistent percentage drops across Low and High settings indicate that the game's engine is scaling predictably with resolution, and the component limiting performance is shifting firmly toward the GPU as pixel count increases.

At Medium settings, the measured data includes minimum and maximum frame rates, providing a clearer picture of frame pacing. At 1080p, the average is 197 FPS with a minimum of 167 and a maximum of 226. At 1440p, the average drops to 140 FPS with a minimum of 119 and a maximum of 162. At 4K, the average falls to 87 FPS with a minimum of 74 and a maximum of 100. The gap between minimum and average FPS remains relatively tight at each resolution, suggesting that the RX 6750 XT is delivering consistent frame times without major stutters.

The Ultra preset is where the scaling becomes punishing. The average FPS at 1080p is 101, dropping to 72 at 1440p and then collapsing to 45 at 4K. The 4K Ultra result is 55.4% lower than the 1080p Ultra result, matching the percentage drops seen at other settings. This indicates that the GPU is the primary limiting factor at 4K, especially with the highest graphical fidelity enabled. The data suggests that for a smooth experience at 4K, users should stick to Low or Medium settings, while 1440p and 1080p offer more headroom for higher presets.

GPU Role

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with a Navi 22 chip manufactured on a 7 nm process. It has 12 GB of GDDR6 memory on a 192-bit bus, delivering a bandwidth of 432.0 GB/s. The memory clock runs at 2250 MHz, which translates to 18 Gbps effective. These specifications position the card as a solid 1080p and 1440p performer, and the measured data supports this.

The GPU's boost clock is rated at 2600 MHz, with a game clock of 2495 MHz and a base clock of 2150 MHz. The shading units number 2560, with 160 texture mapping units and 64 render output units. The card also includes 40 ray tracing cores, though their impact in Downfall is not directly measured in the FPS data. The FP32 performance is 13.31 TFLOPS, and the texture rate is 416.0 GTexel/s, which are solid figures for a card in this class.

Looking at the benchmark scores, the RX 6750 XT achieves a Passmark G3D score of 20700 and a Passmark GPU compute score of 9550. In the 3DMark Steel Nomad DX12 test, it scores 2548. The Geekbench Vulkan score is 98089, while the OpenCL score is 16360. These synthetic results place the card in the 71st percentile of all GPUs, with an average benchmark score of 26011. Its nearest rivals include the AMD Radeon R9 M395X (0.5% faster), the AMD FirePro W7100 (0.6% faster), and the AMD FirePro D700 (0.7% faster), showing that the card sits in a tightly contested performance band.

The VRAM capacity of 12 GB is relevant for Downfall at higher resolutions. The data shows that at 4K Ultra, the average FPS falls to 45, which is playable but not ideal for a horror game where smooth motion matters. At 4K Medium, the average rises to 87 FPS, indicating that the card has enough memory bandwidth to handle the increased resolution, but the shading and texture work at Ultra settings become too demanding. The 432.0 GB/s bandwidth is sufficient for 1440p High, where the card delivers 115 FPS on average.

CPU Role

The Intel Core Ultra 7 265K is a 20-core, 20-thread processor from the Arrow Lake architecture, built on a 3 nm process by TSMC. It has a base clock of 3.90 GHz and a boost clock of 5.50 GHz. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. The memory support is DDR5 with a dual-channel bus and a bandwidth of 102.4 GB/s.

The CPU's benchmark performance is strong, placing it in the 94th percentile of all CPUs. Its average benchmark score is 70879. In Cinebench R23, it scores 35850 in multi-core and 2020 in single-core. The Geekbench scores are 23085 multi-core and 2713 single-core. The Passmark multithread score is 58594, with a single-thread score of 4928. These numbers indicate a processor that should not bottleneck a mid-range GPU in most gaming scenarios.

The nearest rivals to the Core Ultra 7 265K include the Intel Xeon 6511P (0.2% slower), the Intel Xeon Platinum 8270 (0.7% slower), the Intel Core i7-14700KF (1% faster), and the AMD Ryzen 7 9700F (1.3% faster). The performance deltas are small, meaning the 265K is well within the expected range for a high-end desktop CPU.

In Downfall, the CPU's role is evident when looking at the 1080p results. At Low settings, the average FPS reaches 240, which is likely hitting a frame rate cap or the limit of the game engine's simulation thread. The fact that the 1080p Low result is exactly 240 FPS suggests that the CPU is capable of pushing frames well beyond what the GPU can render at higher settings. At 1080p Ultra, the average drops to 101 FPS, which is a 57.9% reduction from the Low preset. This is a larger drop than what is seen at 1440p (from 172 to 72 FPS, a 58.1% reduction) and 4K (from 107 to 45 FPS, a 57.9% reduction). The consistency of these percentage drops across resolutions confirms that the CPU is providing stable data to the GPU, and the performance scaling is almost entirely dictated by the graphics card's workload.

The 20 cores and 20 threads are more than sufficient for a game like Downfall, which is a horror title that likely does not utilize more than a few cores. The high boost clock of 5.50 GHz ensures that single-threaded performance is excellent, which is often the more critical factor in gaming. The data shows no signs of CPU throttling or frame pacing issues, as the minimum FPS figures at Medium settings (167 at 1080p, 119 at 1440p, 74 at 4K) are all reasonably close to their respective averages.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the Low preset delivers an average of 240 FPS. The Medium preset averages 197 FPS, with a minimum of 167 and a maximum of 226. The High preset averages 161 FPS, and the Ultra preset averages 101 FPS. The progression from Low to Ultra shows a steady decrease in frame rate, with the largest single drop occurring between High (161) and Ultra (101), a 37.3% reduction.

At 2560x1440, the Low preset averages 172 FPS. The Medium preset averages 140 FPS, with a minimum of 119 and a maximum of 162. The High preset averages 115 FPS, and the Ultra preset averages 72 FPS. The drop from High to Ultra at 1440p is 37.4%, nearly identical to the 1080p drop, which again points to a consistent GPU workload scaling.

At 3840x2160, the Low preset averages 107 FPS. The Medium preset averages 87 FPS, with a minimum of 74 and a maximum of 100. The High preset averages 72 FPS, and the Ultra preset averages 45 FPS. The drop from High to Ultra at 4K is 37.5%, continuing the pattern. The 4K Low result of 107 FPS is higher than the 1080p Ultra result of 101 FPS, which shows that the GPU has enough headroom to run the game at a higher resolution with lower graphical fidelity.

The minimum FPS values at Medium settings are worth noting. At 1080p, the minimum is 167 FPS, which is 84.8% of the average. At 1440p, the minimum is 119 FPS, which is 85% of the average. At 4K, the minimum is 74 FPS, which is 85.1% of the average. This consistency suggests that the frame pacing is stable across all resolutions at Medium settings, with no sudden drops that would be noticeable in gameplay.

How This Combo Ranks

The Intel Core Ultra 7 265K and AMD Radeon RX 6750 XT combination ranks 1695 out of 3716 tested combos in Downfall. This places it in the 54.4th percentile of all tested systems, meaning it outperforms just over half of the combinations in the database. The rank is a composite metric that takes into account the CPU and GPU performance together, and this mid-pack positioning is expected given the RX 6750 XT's 71st percentile GPU score and the CPU's 94th percentile score.

The gap between the CPU's high percentile and the GPU's mid-range percentile indicates that the graphics card is the limiting factor in this pairing. A more powerful GPU would likely push this combo much higher in the rankings, as the CPU has significant headroom. The CPU's nearest rivals show that it is competitive with other high-end processors, with the Core i7-14700KF being only 1% faster in average benchmark scores. The GPU's nearest rivals include older AMD workstation cards and a mobile RTX 3080 Ti, which are not typical gaming comparisons, but they highlight that the RX 6750 XT is positioned in a specific performance tier.

In practical terms, this rank means the combo is suitable for 1080p and 1440p gaming with high settings, but it will require setting adjustments for 4K. The 4K High average of 72 FPS is playable, but the 4K Ultra average of 45 FPS is below the 60 FPS threshold that many gamers consider the minimum for a smooth experience. The 1440p Ultra average of 72 FPS is a better target for this combo, as it provides a good balance of visual fidelity and performance.

Settings Recommendations

Based on the measured FPS data, the best experience with this combo depends on the target resolution. For 1080p, the High preset at 161 FPS is the recommended choice. It provides a significant visual upgrade over Medium (197 FPS) while still delivering a frame rate that far exceeds the refresh rate of most monitors. The Ultra preset at 101 FPS is also viable, but the 37.3% drop from High may not be worth the visual gains in a horror game where atmosphere and lighting are more important than high-resolution textures.

For 1440p, the Medium preset at 140 FPS is a strong option, but the High preset at 115 FPS is the sweet spot. It offers better visual quality while maintaining a frame rate that is well above 60 FPS. The Ultra preset at 72 FPS is still playable, but it sits close to the threshold where frame drops become noticeable. The minimum FPS at Medium (119) is higher than the average at Ultra (72), which indicates that Medium provides a more consistent experience.

For 4K, the Low preset at 107 FPS is the only setting that provides a high-refresh experience. The Medium preset at 87 FPS is also excellent, with a minimum of 74 FPS that ensures smooth gameplay. The High preset at 72 FPS is borderline, and the Ultra preset at 45 FPS should be avoided for serious play. The data clearly shows that at 4K, the GPU is the limiting factor, so users should prioritize frame rate over graphical fidelity.

The Medium preset is the most balanced across all resolutions. At 1080p it delivers 197 FPS, at 1440p it delivers 140 FPS, and at 4K it delivers 87 FPS. The minimum FPS values at Medium (167, 119, and 74 respectively) are all above the 60 FPS threshold, making this the safest choice for a consistent experience. For users with high-refresh monitors (144Hz or higher), the Low preset at 1080p (240 FPS) or 1440p (172 FPS) is the best way to take advantage of the display's capabilities.
