# Downfall Performance Analysis: AMD Ryzen 5 5600GT + Intel Arc B370

This combination of the AMD Ryzen 5 5600GT and Intel Arc B370 produces playable frame rates at 1080p and 1440p with adjusted settings, but struggles at 4K in this 2016 horror title. The data indicates a GPU-bound configuration at higher resolutions, with the integrated-class Arc B370 acting as the primary performance limiter. The Ryzen 5 5600GT's six Zen 3 cores provide sufficient processing headroom, as evidenced by the frame rate scaling pattern across resolution steps.

Settings Recommendations

The measured data shows a clear performance hierarchy across four quality presets. At 1920x1080, the Low preset delivers an average of 96 FPS, which is the highest frame rate recorded for this combo. However, the Medium preset at 78 FPS average (with a reported range of 67 to 90 FPS) represents the optimal balance for most users, as it maintains a comfortable margin above 60 FPS while providing better visual fidelity than Low. The High preset at 64 FPS remains viable for 60Hz displays, but the Ultra preset drops to 40 FPS, which introduces noticeable stutter in a horror title where smoothness matters for atmosphere.

Moving to 2560x1440, the Medium preset produces 56 FPS average (with a 48 to 64 FPS range), which is the recommended choice for 60Hz panels if the user can tolerate occasional dips. The Low preset at 68 FPS offers the safest experience for competitive or fast-paced sections, while High at 46 FPS and Ultra at 29 FPS fall below the threshold for smooth gameplay. At 3840x2160, even the Low preset only manages 43 FPS average, making 4K impractical for this combination. The Medium preset at 35 FPS (with 30 to 40 FPS range) is the best 4K can offer, but it remains below the 60 FPS target.

The data suggests that for the best experience, users should select Medium at 1080p for a 60+ FPS average with reasonable visual quality. At 1440p, Low or Medium depending on refresh rate priority, and at 4K, only Low or Medium if the user accepts sub-60 FPS gameplay. The 18 FPS Ultra result at 4K is effectively unplayable and should be avoided.

GPU Role

The Intel Arc B370 is an integrated graphics processor based on the Xe3-LPG architecture with the Panther Lake chip, featuring 1280 shading units, 40 texture mapping units, and 20 render output units. Its base clock is 300 MHz with a boost clock of 2400 MHz, producing a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The FP32 compute throughput is 6.144 TFLOPS, with FP16 at 12.29 TFLOPS using a 2:1 ratio. The GPU's TDP is rated at 25 W, and it operates as an IGP with system-shared memory, meaning bandwidth is system-dependent rather than dedicated.

In the 3DMark Steel Nomad DX12 benchmark, the Arc B370 scores 1184, which places it in the 5th percentile of all GPUs. Its nearest rivals in benchmark scores are the ATI Mobility Radeon HD 5570 at 1186 (0.2% higher), ATI Radeon HD 5770 at 1190 (0.5% higher), AMD Radeon HD 7650M at 1192 (0.7% higher), and AMD FirePro M2000 at 1168 (1.4% lower). This context is crucial for understanding the GPU's limited capacity: it performs at a level comparable to discrete GPUs from over a decade ago, which explains the frame rate ceiling observed in Downfall.

The GPU's shared memory architecture means that VRAM size and bandwidth are not fixed specifications but depend on the system's RAM configuration. This creates a scenario where texture-heavy scenes at higher resolutions can suffer from memory bandwidth limitations, contributing to the steep performance drop at 4K. The 10 ray tracing cores and DirectX 12 Ultimate support are present, but the raw rasterization performance is the determining factor for this title's frame rates.

How This Combo Ranks

In the overall ranking for Downfall, this combination of AMD Ryzen 5 5600GT and Intel Arc B370 sits at position 2688 out of 2928 tested combos, placing it in the bottom 8.2% of all configurations. This low ranking is directly attributable to the GPU's weak performance profile, as the CPU is a mid-range part that ranks at the 74th percentile among all processors in general benchmarks.

The CPU's average benchmark score of 20733 puts it within 0.5% of several rival processors: Intel Core i5-12490F at 20802 (-0.3% delta), Intel Xeon 6325P at 20821 (-0.4%), Intel Core Ultra 5 125U at 20826 (-0.4%), and AMD EPYC 7J13 at 20845 (-0.5%). This indicates the Ryzen 5 5600GT is a capable processor that can hold its own against a range of desktop and mobile parts. However, the GPU's 5th percentile ranking drags the combined score down dramatically.

The ranking disparity between the CPU (74th percentile) and GPU (5th percentile) creates a heavily imbalanced system. In Downfall, this manifests as a situation where the processor is rarely the bottleneck, but the GPU cannot deliver high frame rates even at lower resolutions. The combo's rank of 2688 out of 2928 reflects this GPU-limited reality, and users should expect performance consistent with a low-end integrated graphics solution rather than a discrete GPU pairing.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are: Low at 96 FPS, Medium at 78 FPS (with a minimum of 67 and maximum of 90), High at 64 FPS, and Ultra at 40 FPS. The progression from Low to Ultra shows a 58.3% drop in average FPS, which is a substantial penalty for the higher quality settings. The Medium preset's reported range of 67 to 90 FPS indicates some scene-to-scene variability, but the average remains solidly above 60 FPS.

At 2560x1440, the averages are: Low at 68 FPS, Medium at 56 FPS (with a 48 to 64 FPS range), High at 46 FPS, and Ultra at 29 FPS. The transition from 1080p to 1440p reduces frame rates by approximately 29-30% across all settings, which is consistent with the increased pixel count of 1.78x. The Medium preset at 1440p shows a 28.2% drop from its 1080p counterpart, while Low drops 29.2%, High drops 28.1%, and Ultra drops 27.5%.

At 3840x2160, the averages are: Low at 43 FPS, Medium at 35 FPS (with a 30 to 40 FPS range), High at 29 FPS, and Ultra at 18 FPS. The 4K results show a much steeper degradation, with Low dropping 55.2% from 1080p, Medium dropping 55.1%, High dropping 54.7%, and Ultra dropping 55.0%. This consistent ~55% drop from 1080p to 4K, despite the 4x pixel increase, suggests that the GPU is not purely pixel-bound but is also limited by other factors such as memory bandwidth.

The Ultra preset at 4K at 18 FPS is the worst measured result, while the Low preset at 1080p at 96 FPS is the best. The Medium preset across all resolutions provides the most stable experience in terms of consistency, with the narrowest relative gap between minimum and maximum FPS.

Resolution Scaling

The frame rate scaling from 1080p to 1440p shows an average reduction of approximately 29% across all settings. This is notably less than the 44% reduction that would be expected if performance scaled purely with pixel count (from 2.07 million pixels at 1080p to 3.69 million at 1440p). This sub-linear scaling indicates that at 1080p, the GPU is partially bottlenecked by other factors, and the additional pixel load at 1440p does not fully translate to proportional frame rate loss.

From 1440p to 4K, the average reduction is approximately 37% across settings, which is also less than the 2.25x pixel count increase would suggest. However, the cumulative 1080p to 4K drop of approximately 55% shows that the GPU's performance degrades significantly at higher resolutions. The 4K resolution has 4x the pixels of 1080p, yet the frame rate only drops to roughly 45% of the 1080p value, indicating that the limiting factor shifts from pure fill rate to memory bandwidth and shading throughput.

The data reveals that the Intel Arc B370 is not purely resolution-bound. If it were, we would see a 75% drop from 1080p to 4K (matching the pixel count ratio). Instead, the 55% drop suggests that at 1080p, the GPU is already working near its effective limit, and the additional resolution overhead causes diminishing returns. This pattern is typical of GPUs with very limited memory bandwidth, where the system-shared memory configuration becomes a constraining factor at higher resolutions.

The minimal difference between the Low and Ultra scaling patterns (55.2% vs 55.0% from 1080p to 4K) indicates that the GPU's limitations are consistent regardless of settings. This suggests that the bottleneck is at the GPU's fundamental throughput level rather than specific rendering features. The CPU's role in this scaling is minimal, as the Ryzen 5 5600GT provides ample processing power even at 1080p Low where the highest frame rates are achieved.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on the Zen 3 architecture with the Cezanne codename, manufactured on TSMC's 7 nm process. It operates at a base clock of 3.60 GHz with a boost clock of 4.60 GHz, and has a 65 W TDP. The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3 cache. Memory support is dual-channel DDR4 with a bandwidth of 51.2 GB/s, and the CPU uses PCIe Gen 3 with 16 lanes. The processor contains 10,700 million transistors on a 180 mm² die.

In synthetic benchmarks, the CPU demonstrates strong multi-threaded performance with a Cinebench R23 multi-core score of 17272 and a single-core score of 2438. The Geekbench multi-core score is 7986 with a single-core score of 1843, while 3DMark tests show 5523 for 16 threads, 1794 for 2 threads, 3446 for 4 threads, 4968 for 8 threads, 5554 for max threads, and 913 for single thread. PassMark results include a multi-thread score of 20325 and a single-thread score of 3348, with floating point math at 39817, integer math at 69566, and extended instructions at 18041.

The CPU's average benchmark score of 20733 places it at the 74th percentile of all processors, with nearest rivals including the Intel Core i5-12490F at 20802 (-0.3%), Intel Xeon 6325P at 20821 (-0.4%), Intel Core Ultra 5 125U at 20826 (-0.4%), and AMD EPYC 7J13 at 20845 (-0.5%). These tightly clustered scores indicate the Ryzen 5 5600GT is a well-balanced mid-range processor.

In Downfall, the CPU's role is to feed the GPU with draw calls and physics data. The measured frame rates show that at 1080p Low, the system achieves 96 FPS, which is well within the CPU's capability. The fact that frame rates drop consistently across resolutions and settings, rather than plateauing at a CPU-imposed limit, confirms that the GPU is the primary constraint. The 12 threads provide ample parallelism for modern game engines, and the 4.60 GHz boost clock ensures responsive single-threaded performance for game logic.

The integrated Radeon Vega 7 graphics within the CPU are not used in this configuration, as the system employs the discrete-class Intel Arc B370. However, the CPU's memory controller and PCIe Gen 3 interface play a role in the GPU's system-shared memory access, potentially influencing the bandwidth-dependent performance observed at higher resolutions. The 16 MB L3 cache helps mitigate some memory latency, but the GPU's shared memory architecture remains the critical limitation.
