Downfall

Resolution Scaling

The measured FPS data for Downfall with the Intel Core i5-14400F and AMD Radeon RX 6800 XT reveals a clear pattern of GPU-bound scaling across the three tested resolutions. At 1920x1080 with Ultra settings, the combo delivers 124.1 FPS average. Moving to 2560x1440 at Ultra, the average drops to 84.7 FPS, a reduction of 31.7%. At 3840x2160 Ultra, the average falls further to 55.7 FPS, representing a 34.2% drop from the 1440p figure. This steep decline as resolution increases is the classic signature of a GPU-limited workload; the Radeon RX 6800 XT is the constraining component at higher pixel counts.

The scaling pattern becomes more pronounced when examining the lower settings tiers. At 1920x1080 Low, the system hits 289.7 FPS. At 2560x1440 Low, it still manages 205.5 FPS, a 29.1% decrease. At 3840x2160 Low, the average is 127.4 FPS, another 38.0% reduction. The consistent 30-40% performance penalty per resolution step, even at Low settings where the CPU would have more headroom to stretch, indicates that the RX 6800 XT's rendering throughput is the primary limiter. The i5-14400F, with its 10 cores and 16 threads, appears more than capable of feeding the GPU at these frame rates; the data does not show a CPU bottleneck plateau at 1080p, as frame rates continue to scale substantially with resolution changes.

Between High and Ultra settings at 4K, the gap is particularly stark. High averages 85.5 FPS while Ultra drops to 55.7 FPS, a 34.8% performance hit for the highest quality tier. The same comparison at 1440p shows 141.5 FPS on High versus 84.7 FPS on Ultra, a 40.1% drop. This suggests that the Ultra preset in Downfall introduces a significant rendering cost, likely related to shadow quality or post-processing effects, that heavily taxes the GPU's 4608 shading units and 128 ROPs. The scaling data points to a component pairing where the CPU is rarely the bottleneck; the RX 6800 XT is doing the heavy lifting, and its architecture determines the frame rate ceiling at every resolution and settings combination.

Q: What are the GPU's memory specifications?

A: The Radeon RX 6800 XT features 16 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 512.0 GB/s. The memory clock is 2000 MHz, which translates to 16 Gbps effective. This large memory pool and high bandwidth are well-suited for the high-resolution textures and effects present in Downfall's Ultra preset.

GPU Role

The AMD Radeon RX 6800 XT is the dominant component in this pairing, and its specifications explain the measured frame rates. Built on the Navi 21 chip using RDNA 2.0 architecture at TSMC's 7 nm process, the GPU contains 26,800 million transistors on a 520 mm² die. It operates at a base clock of 1825 MHz, with a game clock of 2015 MHz and a boost clock of 2250 MHz. These clock speeds, combined with 4608 shading units, 288 TMUs, and 128 ROPs, deliver a peak FP32 throughput of 20.74 TFLOPS. The 72 ray accelerators also support the game's horror-themed lighting effects, though the measured data does not isolate ray tracing performance.

The memory subsystem is a critical factor for Downfall's high-resolution performance. With 16 GB of GDDR6 on a 256-bit bus, the GPU achieves 512.0 GB/s of bandwidth. At 4K Ultra, where texture data and frame buffers grow substantially, this bandwidth is sufficient to maintain 55.7 FPS. The 16 GB capacity also means the GPU is unlikely to spill over into system memory, which would cause severe stuttering; the fact that the data shows smooth average frame rates without reported minimums suggests the memory pool is adequate. The GPU's pixel rate of 288.0 GPixel/s and texture rate of 648.0 GTexel/s are the raw metrics that govern how fast it can fill the screen and apply texture maps, directly correlating with the measured FPS at each resolution.

The GPU's production status is end-of-life, and its launch MSRP was 649 USD. In the benchmark hierarchy, it sits at the 87th percentile of all GPUs. Its nearest rival, the Intel Arc A550M, scores 49737 (deltaPct 0.5), while the NVIDIA RTX A1000 scores 50826 (deltaPct -1.7). These close deltas indicate the RX 6800 XT is competitively positioned among its peers. The 300 W TDP and 700 W suggested PSU rating are the practical requirements for sustaining the clock speeds that produce the frame rates observed in Downfall across all resolution and settings combinations.

How This Combo Ranks

Out of 1741 tested hardware combinations for Downfall, this pairing of the Intel Core i5-14400F and AMD Radeon RX 6800 XT achieves a rank of 595. This places it in the 65.8th percentile of all configurations, meaning it outperforms roughly two-thirds of the tested combos while trailing the top third. The rank reflects the balance between the CPU's 88th percentile standing among all processors and the GPU's 87th percentile among all GPUs; both components are above-average, but neither is at the extreme high end.

The CPU's nearest rivals provide context for its contribution to this rank. The Intel Core i7-12800H has an average score of 32513 with a deltaPct of 0, meaning it is statistically identical to the i5-14400F (32508). The AMD Ryzen 5 PRO 7645 trails by 0.2% (32446), and the Intel Core i7-13705H also trails by 0.2% (32586). These negligible differences mean that swapping the i5-14400F for any of these rivals would likely produce nearly identical frame rates in Downfall, confirming that the CPU is not the differentiator in this combo's rank.

The GPU's nearest rivals show a similar clustering. The Intel Arc A550M scores 49737 (deltaPct 0.5), the NVIDIA CMP 50HX scores 49071 (deltaPct 1.9), and the NVIDIA GeForce RTX 4070 Ti SUPER scores 48704 (deltaPct 2.6). The RX 6800 XT's score of 49982 puts it ahead of all these alternatives by a small margin. This suggests that the combo's rank is driven primarily by the GPU's slight edge over its immediate competitors, combined with the CPU's solid mid-range compute performance. The rank of 595 out of 1741 is a credible result for a mid-to-high-end pairing, and the measured FPS data supports that this configuration can handle Downfall smoothly at 1440p and even at 4K with settings adjustments.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 289.7 FPS average, which is an exceptionally high figure indicating the GPU is nowhere near its limit. Medium settings reach 234.7 FPS, High settings manage 195.5 FPS, and Ultra settings drop to 124.1 FPS. The step from High to Ultra at 1080p represents a 36.5% reduction (71.4 FPS), which is the largest single-step drop in this resolution tier. All 1080p results exceed the typical 60 FPS target by a wide margin, and even the Ultra preset comfortably clears 120 FPS.

At 2560x1440, the performance remains strong but shows the expected scaling penalty. Low settings average 205.5 FPS, which is still well above high-refresh-rate monitors. Medium settings hit 168.3 FPS, High settings produce 141.5 FPS, and Ultra settings fall to 84.7 FPS. The transition from High to Ultra at 1440p costs 56.8 FPS, a 40.1% drop that mirrors the pattern seen at 1080p. For users targeting a 144 Hz display, Medium and High presets are the appropriate choices, while Ultra would require a 60 Hz panel or adaptive sync to feel smooth.

At 3840x2160, the GPU's limits become clearly visible. Low settings still produce a playable 127.4 FPS, and Medium settings manage 106.7 FPS. High settings drop to 85.5 FPS, which remains fluid for most users. Ultra settings, however, fall to 55.7 FPS, which is below the 60 FPS threshold and would be noticeable in a fast-paced horror title. The scaling from High to Ultra at 4K is a 34.8% reduction (29.8 FPS), which is slightly less severe than at lower resolutions but still significant. The data indicates that 4K gaming is viable with this combo only at Medium or High settings, while 1440p and 1080p allow for the full range of quality options without sacrificing playability.
