Downfall

# Downfall with Intel Core Ultra 5 235 + AMD Radeon RX 580

The Intel Core Ultra 5 235 paired with the AMD Radeon RX 580 produces a playable but constrained experience in Downfall, a 2016 horror title. The CPU sits in the 89th percentile among all processors, while the GPU lands in the 53rd percentile, creating a clear imbalance where the graphics card becomes the primary bottleneck at higher resolutions. The measured frame rates across 1080p, 1440p, and 4K show a system that can handle the game at medium settings, but struggles to maintain smooth performance when pushed toward high or ultra presets.

Resolution Scaling

The frame rate drop from 1080p to 4K demonstrates how heavily the RX 580 limits this pairing. At Low settings, the average FPS falls from 102 at 1080p to 73 at 1440p and then to 45 at 4K. That represents a 29% reduction moving from 1080p to 1440p, and a further 38% drop when going from 1440p to 4K. The scaling is not linear, indicating that the GPU's pixel throughput becomes increasingly strained as resolution climbs.

At Medium settings, the pattern continues but with a steeper overall decline. The average FPS moves from 83 at 1080p to 60 at 1440p and finally to 37 at 4K. The 4K result includes a minimum of 32 FPS and a maximum of 43 FPS, showing noticeable variance. This suggests that the RX 580's 256-bit memory bus and 256.0 GB/s bandwidth are being saturated at 4K, causing frame time inconsistencies.

High settings reveal an even more pronounced bottleneck. The average FPS drops from 68 at 1080p to 49 at 1440p, then to 30 at 4K. The 4K average of 30 FPS is technically playable but borders on uncomfortable for a horror game where smooth motion matters for atmosphere. Ultra settings are the most demanding, with averages of 43 at 1080p, 31 at 1440p, and just 19 at 4K — the latter being effectively unplayable.

The resolution scaling data indicates that the limiting component is unambiguously the GPU. The Core Ultra 5 235, with its 14 cores and 5.00 GHz boost clock, is not the constraint here. If the CPU were the bottleneck, we would expect similar FPS across resolutions at the same settings. Instead, the consistent degradation from 1080p to 4K points directly at the RX 580's Polaris 20 chip, which was designed for 1080p gaming when it launched in 2017.

Settings Recommendations

For 1080p gaming, the data supports Medium as the sweet spot. The average FPS of 83 with a minimum of 71 and maximum of 96 provides a stable experience well above the 60 FPS threshold. Low settings push this to 102 average, which is smoother but sacrifices visual fidelity. High at 68 average is still respectable, but the gap between High and Medium is only 15 FPS, making Medium the better choice for headroom during intense scenes.

At 1440p, Medium remains the recommended preset. The average of 60 FPS with a minimum of 51 and maximum of 69 is exactly at the playability line. Low settings offer 73 average, which provides more comfort, but Medium's visual improvements are worth the modest FPS cost. High at 49 average is borderline, while Ultra at 31 average is not recommended for sustained play.

For 4K, the options are limited. Low settings produce a 45 average, which is playable but visually basic. Medium drops to 37 average with a minimum of 32, which will feel stuttery in a horror game where reaction time matters. High at 30 average is technically playable but inconsistent. Ultra at 19 average is not viable. The data suggests that 4K should only be attempted at Low or Medium settings, and even then, players should expect compromises.

Given the game's 2016 release date and horror genre, the measured rows indicate that 1080p Medium is the best overall experience. It delivers 83 average FPS, which is smooth enough for the game's atmospheric tension, while maintaining visual quality that suits the title's aesthetic. For 1440p users, Medium at 60 average is acceptable, but they should be prepared for occasional dips to 51 FPS.

GPU Role

The AMD Radeon RX 580 is the decisive component in this pairing. Its 8 GB of GDDR5 memory on a 256-bit bus provides 256.0 GB/s of bandwidth, which is adequate for 1080p but becomes a limiting factor at higher resolutions. The memory clock runs at 2000 MHz with 8 Gbps effective speed, and the GPU operates at a base clock of 1257 MHz with a boost of 1340 MHz.

The GPU's compute capabilities are modest by modern standards. The Polaris 20 chip, built on a 14 nm process at GlobalFoundries, delivers 6.175 TFLOPS of FP32 performance. It has 2304 shading units, 144 texture mapping units, and 32 ROPs. The pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s explain why 4K resolution causes such a significant performance drop — the ROP count is simply too low to fill 8.3 million pixels per frame efficiently.

In the benchmark database, the RX 580 sits at the 53rd percentile among all GPUs with an average benchmark score of 12928. Its nearest rivals include the NVIDIA GeForce RTX 3050 Ti Mobile with a score of 12940 (a 0.1% difference) and the NVIDIA GeForce GTX 1660 SUPER at 12986 (0.4% higher). This places the RX 580 in the middle of the pack, roughly equivalent to a modern entry-level laptop GPU.

The measured FPS in Downfall reflects this positioning. The GPU can handle the game at 1080p Medium with ease, but the 4K Ultra result of 19 average FPS shows its age. The 8 GB VRAM is sufficient for this game's textures, but the computational throughput is not enough for high-resolution rendering. The GPU's DirectX 12 support (version 12_0) and Vulkan 1.3 API compatibility are adequate for Downfall, but the hardware lacks the features found in newer architectures.

CPU Role

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor from the Arrow Lake architecture, built on a 3 nm process at TSMC. It has a base clock of 3.40 GHz and a boost clock of 5.00 GHz, with 24 MB of shared L3 cache. The CPU supports DDR5 memory on a dual-channel bus with 102.4 GB/s bandwidth, and it uses PCIe Gen 5 with 20 lanes.

In Downfall, the CPU's role is secondary to the GPU. The game is not particularly CPU-intensive, and the Core Ultra 5 235's single-thread performance of 2085 in Cinebench R23 is more than sufficient for the game's logic and AI. The 14 cores provide ample headroom for background tasks, but the game likely uses only a few threads, making the high boost clock more relevant than core count.

The CPU's benchmark profile shows strong performance across the board. Its PassMark single-thread score of 4516 and multithread score of 37816 place it well above the needs of a 2016 horror title. The Cinebench R20 scores of 875 single-core and 6202 multi-core confirm that this processor can handle any game logic Downfall throws at it.

However, the CPU cannot compensate for the GPU's limitations. Even with the CPU running at its 5.00 GHz boost clock, the RX 580's 6.175 TFLOPS of compute performance caps the frame rate at the values shown in the measured data. This is a classic case of GPU bottlenecking — the processor is waiting on the graphics card to complete each frame.

The CPU's 65 W TDP and 3 nm process make it an efficient partner, but this efficiency does not translate into higher frame rates in Downfall. The game's performance is dictated by the GPU's pixel throughput and memory bandwidth, not by CPU clock speed or core count. The measured FPS at 1080p Low (102 average) approaches the practical limit for this GPU, and no CPU upgrade would push it significantly higher.

Measured FPS Breakdown

At 1920x1080, the full range of settings produces playable results. Low settings yield 102 average FPS, which is smooth and responsive. Medium settings deliver 83 average FPS with a minimum of 71 and maximum of 96, providing consistent performance for most scenes. High settings reduce the average to 68 FPS, still playable but with less headroom. Ultra settings drop to 43 average FPS, which is borderline for a game requiring quick reactions.

At 2560x1440, the performance gap between settings widens. Low settings maintain 73 average FPS, which is comfortable. Medium settings produce 60 average FPS with a minimum of 51 and maximum of 69, placing it right at the playability threshold. High settings fall to 49 average FPS, which will be noticeable in fast-moving scenes. Ultra settings drop to 31 average FPS, which is not recommended for sustained play.

At 3840x2160, the GPU's limitations become severe. Low settings produce 45 average FPS, which is playable but visually sparse. Medium settings deliver 37 average FPS with a minimum of 32 and maximum of 43, creating inconsistent frame pacing. High settings drop to 30 average FPS, which is technically playable but will feel sluggish. Ultra settings produce 19 average FPS, which is effectively unplayable for a horror game requiring atmospheric tension.

The combination ranks 2670 out of 2928 tested combos in Downfall, placing it in the bottom 9% of systems tested. This low rank is primarily due to the GPU's age, not the CPU. The Core Ultra 5 235 is a modern processor with top-tier benchmark scores, but the RX 580's mid-range performance (53rd percentile) drags the overall experience down at higher resolutions. For 1080p gaming at Medium settings, the pairing works well; for anything above that, the GPU becomes the limiting factor.
