Downfall

The AMD Ryzen 9 9900X3D and Intel Arc B570 pairing delivers a playable but heavily GPU-bound experience in Downfall, with the data showing a clear ceiling imposed by the graphics card at higher resolutions. The combo ranks in the lower-mid tier of tested configurations, and the measured frames per second (FPS) reveal a system that excels at 1080p but struggles to maintain smooth performance at 4K with maxed-out settings.

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

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor from the 9000 series, built on the Zen 5 architecture (Granite Ridge) using a 4 nm process at TSMC. It operates with a base clock of 4.40 GHz and a boost clock of 5.50 GHz, backed by a substantial 128 MB of L3 cache. This is a desktop-class chip on the AMD Socket AM5 platform, supporting DDR5 memory in a dual-channel configuration with 89.6 GB/s of bandwidth. In synthetic benchmarks, the CPU demonstrates strong multi-threaded capability with a Cinebench R23 multicore score of 47737 and a single-core score of 6739, while Geekbench multicore reaches 22884 and single-core 3041. Its average benchmark score of 54762 places it in the 91st percentile of all CPUs tested.

For Downfall, a horror title from 2016, this processor is overwhelmingly capable of handling the game's logic and physics. The data shows that at 1080p with Low settings, the combo reaches 163 FPS, which is well beyond what the game's engine likely requires for smooth play. The CPU's single-thread performance, as evidenced by the 3DMark single-thread score of 1269, ensures that the game's primary simulation thread is not a bottleneck. The 12 cores and 24 threads provide ample headroom for any background tasks or streaming workloads while gaming. In the nearest rivals list, the 9900X3D sits within a narrow band of performance: it is 0.6% behind the Intel Core Ultra 5 245KF, 1.3% ahead of the Intel Core Ultra 5 245K, 2% ahead of the Intel Xeon 6505P, and 2.1% ahead of the Intel Core i7-14700F. This indicates that the CPU's raw compute is competitive with modern mid-range and high-end desktop parts, meaning it is unlikely to be the limiting factor in this game. The measured FPS deltas across resolutions and settings support this: the performance drop from 1080p Low to 4K Low is from 163 to 72 FPS, a 56% reduction that falls squarely on the GPU's shoulders rather than any CPU limitation.

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

The Intel Arc B570 is the graphics component here, based on the Xe2-HPG architecture (Battlemage generation) with the BMG-G21 chip on a 5 nm TSMC process. It features 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The GPU operates at a boost clock of 2500 MHz, with memory running at 2375 MHz (19 Gbps effective). Its compute resources include 2304 shading units, 144 texture mapping units, and 80 raster operation units, along with 18 ray tracing cores. The FP32 performance is rated at 11.52 TFLOPS, with a pixel rate of 200.0 GPixel/s and a texture rate of 360.0 GTexel/s. In benchmark tests, the GPU scores 14195 in Passmark G3D and 2649 in 3DMark Steel Nomad, placing it in the 65th percentile of all GPUs.

In Downfall, the Arc B570 is the clear performance limiter. The benchmark results indicate that the GPU's 10 GB VRAM is sufficient for the game's demands at all tested settings, as there are no anomalies suggesting memory overflow. However, the raw throughput is not enough to maintain high frame rates at 4K. At 4K Ultra, the average FPS drops to 30, which is a marginal playable level for a horror title where atmospheric pacing can mask lower frame rates, but it is far from ideal. The GPU's nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (0.1% faster), the Intel Arc A750 (0.1% slower), the NVIDIA Quadro M4000M (0.4% faster), and the AMD Radeon R9 M390X (0.5% slower). This places the B570 in a performance tier that is competitive with older mid-range desktop and modern mobile parts, which is consistent with the measured FPS figures. The GPU's clock speed of 2500 MHz is decent, but the relatively narrow 160-bit memory bus and 10 GB frame buffer limit its ability to push large textures at high resolutions. The data shows that the GPU is the bottleneck at every resolution above 1080p, as the FPS scaling is not proportional to the CPU's capabilities.

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

The measured FPS data across resolutions and settings provides a clear picture of where the bottleneck lies. At 1080p, the combo delivers strong performance: Low settings hit 163 FPS, Medium averages 133 FPS (with a minimum of 113 and maximum of 153), High reaches 109 FPS, and Ultra drops to 68 FPS. Moving to 1440p, the frame rates fall significantly: Low averages 116 FPS, Medium 95 FPS (min 81, max 110), High 78 FPS, and Ultra 49 FPS. At 4K, the performance collapses further: Low averages 72 FPS, Medium 59 FPS (min 50, max 68), High 49 FPS, and Ultra 30 FPS.

The scaling pattern is revealing. From 1080p Low to 1440p Low, the FPS drops from 163 to 116, a 29% reduction. From 1440p Low to 4K Low, it drops from 116 to 72, a 38% reduction. This consistent degradation across resolutions indicates that the GPU is the limiting component. If the CPU were the bottleneck, we would expect the FPS to remain relatively flat when lowering the resolution, but instead, the frame rate scales almost linearly with pixel count. At 1080p Ultra, the 68 FPS average suggests the GPU is already under significant load, and the jump to 4K Ultra (30 FPS) shows a 56% drop, which is consistent with the 4x increase in pixel count from 1080p to 4K. The CPU's role is to feed the GPU with draw calls and physics calculations, and the 9900X3D is more than capable of doing so at these frame rates. The data clearly shows that for a smoother 4K experience, users would need a more powerful GPU, while the CPU has ample headroom for future upgrades.
