Downfall

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

The Intel Core Ultra 5 225 is a 10-core, 10-thread desktop processor built on the Arrow Lake architecture and TSMC's 3 nm process node. It operates with a base clock of 3.30 GHz and a boost clock of 4.90 GHz, drawing a 65 W TDP. The CPU features a 20 MB shared L3 cache, with 192 KB of L1 cache per core and 3 MB of L2 cache per core. It supports DDR5 memory over a dual-channel bus, delivering a memory bandwidth of 102.4 GB/s.

In Downfall, a horror title that tends to stress single-thread performance for game logic and physics, the Core Ultra 5 225's high boost clock is a decisive factor. The benchmark data shows that at 1080p with Low settings, the combo achieves 299 FPS average, which is the highest measured frame rate across all resolution and settings combinations. This suggests the CPU is capable of feeding the GPU with frames efficiently at lower graphical loads, where the processor's single-thread capabilities become the primary limiter.

The CPU's Cinebench R23 single-core score of 3655 and multi-core score of 25891 indicate strong per-thread performance relative to its multi-threaded output. The single-core score places it in the 85th percentile of all CPUs, which means it outperforms the vast majority of processors in tasks that rely on one or few threads. For Downfall, which is not a heavily threaded game, this single-core strength is more relevant than the raw multi-core throughput. The multi-core score does matter for background tasks and any additional system load, but the game itself will primarily benefit from the 4.90 GHz boost clock.

The nearest rivals for this CPU, based on average benchmark scores, include the AMD Ryzen 5 5600F with a delta of 0%, the AMD Ryzen 5 5500X3D at -0.2%, the AMD Ryzen AI 7 PRO 450 at -0.4%, and the Intel Core i9-12900T at -0.5%. These comparisons show that the Core Ultra 5 225 is essentially on par with these processors in overall compute benchmarks, with differences of less than one percent. In the context of Downfall, where the CPU is unlikely to be the bottleneck at higher resolutions, this parity means the game's performance will be determined more by the GPU and the selected settings than by the choice among these CPUs.

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

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with a GA102 chip, manufactured on Samsung's 8 nm process. It features 10 GB of GDDR6X memory on a 320-bit bus, providing a bandwidth of 760.3 GB/s. The GPU has a base clock of 1440 MHz and a boost clock of 1710 MHz, with memory clocked at 1188 MHz (19 Gbps effective). The card includes 8704 shading units, 272 texture mapping units, and 96 raster operation units, along with 68 RT cores and 272 tensor cores. Its peak FP32 performance is rated at 29.77 TFLOPS.

In Downfall, the RTX 3080's role is significant across all measured settings, but the data reveals how VRAM and clock speeds interact with the game's demands. At 4K Ultra, the combo averages 56 FPS, which is a substantial drop from the 89 FPS at 4K High. This 33 FPS difference indicates that the Ultra preset imposes a heavy load on the GPU, likely due to increased texture detail and shading complexity that push the 10 GB VRAM buffer to its limits. The 4K Medium setting yields 109 FPS average with a minimum of 92 FPS and a maximum of 125 FPS, showing that stepping down from Ultra to Medium provides a 53 FPS improvement.

The GPU's performance relative to its peers, based on average benchmark scores, places it at the 68th percentile of all GPUs. Its nearest rivals include the NVIDIA P106-100 at -0.3%, the AMD Radeon Pro Vega 16 at -0.3%, the AMD Radeon RX 6600M at -0.4%, and the AMD Radeon R9 M290X at -0.4%. These deltas are minimal, indicating that the RTX 3080's raw compute performance is closely matched by these other cards in synthetic benchmarks. However, in Downfall, the actual frame rates are what matter, and the data shows that the RTX 3080 can deliver playable performance even at 4K, provided the settings are tuned appropriately.

The GPU's memory bandwidth of 760.3 GB/s is a key asset for a game like Downfall, which may involve high-resolution textures and complex lighting effects. At 4K, the bandwidth helps maintain frame rates, but the 10 GB VRAM capacity becomes a constraint at Ultra settings. The data shows a clear pattern: as settings increase from Low to Ultra, the average FPS drops consistently across all resolutions, but the magnitude of the drop grows at higher resolutions. This suggests that the GPU is the limiting component at 4K, especially when VRAM usage exceeds the available capacity.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium preset offers the most balanced experience across all resolutions. At 1080p, Medium produces an average of 245 FPS with a minimum of 208 FPS and a maximum of 282 FPS. This is a 54 FPS drop from Low (299 FPS) but a 120 FPS gain over Ultra (125 FPS). The minimum FPS of 208 at 1080p Medium ensures smooth gameplay without significant frame drops, which is critical for a horror game where sudden stutters can break immersion.

At 1440p, Medium averages 175 FPS with a minimum of 149 FPS and a maximum of 201 FPS. This provides a comfortable margin above standard 144 Hz monitors, ensuring the display can be fully utilized. The jump from Medium to High at 1440p reduces the average to 143 FPS, which is still playable but closer to the refresh rate limit. Ultra at 1440p drops to 90 FPS, which is acceptable for slower-paced horror gameplay but not ideal for maintaining high refresh rate smoothness.

At 4K, Medium is the recommended setting, yielding 109 FPS average with a minimum of 92 FPS and a maximum of 125 FPS. This is well above the 60 FPS threshold, providing a fluid experience even on a 4K display. High at 4K drops to 89 FPS average, which is still playable but leaves less headroom for demanding scenes. Ultra at 4K averages 56 FPS, which dips below the desirable 60 FPS target and may result in noticeable judder during fast camera movements.

The data clearly shows that Low settings offer the highest frame rates, but they likely sacrifice visual fidelity in a horror game where atmosphere and lighting are crucial. Ultra settings, while visually impressive, impose too heavy a penalty on frame rates, especially at higher resolutions. Medium strikes the optimal balance, delivering frame rates that are 1.8 to 2.2 times higher than Ultra across all resolutions while maintaining better visual quality than Low. For 1080p and 1440p users with high refresh rate displays, the 245 FPS and 175 FPS averages at Medium respectively are excellent. For 4K users, the 109 FPS average at Medium ensures a smooth and visually coherent experience.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Intel Core Ultra 5 225 paired with the NVIDIA GeForce RTX 3080 ranks 776th out of 2928 tested combos in Downfall. This places the combo in the top 26.5% of all tested systems, indicating that it delivers above-average performance for this game. The rank of 776 is derived from the measured FPS data across all resolutions and settings, which positions this combo well above the median but not among the top performers.

Given that the RTX 3080 sits at the 68th percentile of all GPUs and the Core Ultra 5 225 at the 85th percentile of all CPUs, the combo's rank of 776 out of 2928 is consistent with the expectation that it will outperform a majority of systems. The GPU's percentile is lower than the CPU's, which suggests that the graphics card is the more limiting factor in this pairing for Downfall. This is further supported by the FPS data, where the performance scales more dramatically with resolution and settings changes than would be expected if the CPU were the primary bottleneck.

The rank of 776 means that 2152 tested combos deliver lower performance in Downfall, while 775 combos deliver higher performance. The combos that rank higher likely feature more powerful GPUs, such as the RTX 3080's successors or higher-tier cards with more VRAM and higher clock speeds. However, for a horror game like Downfall, the performance at this rank is more than sufficient for a smooth and immersive experience, especially when using the Medium preset as recommended.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS data reveals a clear scaling pattern from 1080p to 4K, which indicates that the GPU is the primary limiting component in this combo. At Low settings, the average FPS drops from 299 at 1080p to 214 at 1440p (a 28.4% decrease) and then to 133 at 4K (a 55.5% decrease from 1440p). This consistent drop with increasing resolution is a hallmark of GPU-bound performance, as the CPU's frame production capability remains constant while the GPU's rendering load increases with pixel count.

A similar pattern is observed at Medium settings, where the average FPS goes from 245 at 1080p to 175 at 1440p (a 28.6% decrease) and then to 109 at 4K (a 37.7% decrease from 1440p). The percentage drop from 1440p to 4K is smaller at Medium than at Low, which suggests that the rendering overhead at higher settings partially offsets the resolution scaling. At High settings, the FPS drops from 201 at 1080p to 143 at 1440p (a 28.9% decrease) and then to 89 at 4K (a 37.8% decrease from 1440p). The pattern is consistent: a roughly 28-29% drop from 1080p to 1440p, followed by a 37-55% drop from 1440p to 4K.

The Ultra settings show the most dramatic scaling, with FPS dropping from 125 at 1080p to 90 at 1440p (a 28% decrease) and then to 56 at 4K (a 37.8% decrease from 1440p). The fact that the percentage drop from 1080p to 1440p is nearly identical across all settings (28-29%) indicates that the GPU is consistently the bottleneck in this resolution range. The larger percentage drop from 1440p to 4K at Low settings (55.5%) compared to other settings (37-38%) is interesting, as it suggests that at Low settings, the GPU is so lightly loaded at 1440p that the jump to 4K creates a proportionally larger load increase.

Overall, the resolution scaling data confirms that the RTX 3080 is the limiting component in this combo for Downfall. The CPU's performance, while strong, is not the bottleneck at any resolution or setting, as evidenced by the fact that the FPS scales predictably with resolution changes. For users who want to maximize frame rates at lower resolutions, the CPU can keep up, but at 4K, the GPU's workload becomes the deciding factor.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1080p:

• Low: 299 FPS average
• Medium: 245 FPS average, with a minimum of 208 FPS and a maximum of 282 FPS
• High: 201 FPS average
• Ultra: 125 FPS average

At 1080p, the combo delivers frame rates that are well above the refresh rates of most monitors. Even at Ultra settings, the 125 FPS average is sufficient for a smooth experience on a standard 120 Hz display. The jump from Low to Medium costs 54 FPS, while the jump from Medium to High costs 44 FPS, and from High to Ultra costs 76 FPS. The Ultra preset imposes the largest performance penalty, indicating that it introduces effects that are disproportionately demanding relative to the visual improvement.

1440p:

• Low: 214 FPS average
• Medium: 175 FPS average, with a minimum of 149 FPS and a maximum of 201 FPS
• High: 143 FPS average
• Ultra: 90 FPS average

At 1440p, the Medium preset's minimum of 149 FPS ensures that the frame rate never dips below the 144 Hz refresh rate threshold, providing a consistent high-refresh experience. The High preset's 143 FPS average is just below this threshold, which could result in occasional frame drops below 144 FPS. Ultra at 90 FPS is still playable but represents a significant step down in smoothness. The performance scaling from Low to Ultra at 1440p mirrors the 1080p pattern, with Ultra being the most demanding preset.

4K:

• Low: 133 FPS average
• Medium: 109 FPS average, with a minimum of 92 FPS and a maximum of 125 FPS
• High: 89 FPS average
• Ultra: 56 FPS average

At 4K, the Medium preset is the only one that maintains an average above 100 FPS, with a minimum of 92 FPS that stays above the 60 FPS target. High at 89 FPS is close behind, but the minimum FPS is not measured, so there is a risk of drops below 60 FPS in demanding scenes. Ultra at 56 FPS is below the 60 FPS threshold, which could lead to noticeable stuttering in a horror game where smooth camera movement is important. The Low preset at 133 FPS provides the highest frame rate but sacrifices visual quality.

The data shows that the combo's performance is best described by the Medium preset, which offers the most consistent experience across all resolutions. The measured minimum FPS values for Medium at each resolution (208 at 1080p, 149 at 1440p, 92 at 4K) demonstrate that the combo can maintain frame rates above the critical thresholds for smooth gameplay, even in the most demanding scenes.
