Downfall

# Downfall with AMD Ryzen 5 5600G + Intel Arc B390

This combination of an AMD Ryzen 5 5600G processor and Intel Arc B390 integrated graphics produces playable frame rates at lower resolutions in Downfall, but the GPU becomes the clear limiting factor as resolution climbs. The Intel Arc B390, built on the Xe3-LPG architecture using a 3 nm process, sits at the 9th percentile among all GPUs in the database, placing it in the bottom tier of graphics hardware. The Ryzen 5 5600G, by contrast, performs near the middle of the CPU pack at the 74th percentile, with an average benchmark score of 21,088 that lands within 0.4% of its nearest rivals. This pairing yields a combo rank of 2,589 out of 2,928 tested combinations in Downfall, indicating that the GPU holds this system back substantially.

Resolution Scaling

The measured frame rates show a steep and consistent decline as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average FPS drops from 106 at 1080p to 76 at 1440p, then falls further to 47 at 4K. That represents a 55.7% reduction from 1080p to 4K at Low settings, which is a severe scaling curve that points directly at the GPU as the bottleneck. A system that were CPU-limited would show a much flatter curve across resolutions, since lowering resolution would reduce GPU load without changing the CPU workload. The data here shows the opposite pattern.

At Medium settings, the scaling is similar: 87 FPS at 1080p drops to 62 FPS at 1440p (a 28.7% reduction), then to 39 FPS at 4K (a further 37.1% reduction from 1440p). The total drop from 1080p Medium to 4K Medium is 55.2%, almost identical to the Low setting curve. This consistency across presets suggests that the GPU's rendering throughput, not any specific setting, is what collapses at higher resolutions. The Intel Arc B390's memory bandwidth is listed as "System Dependent" with system-shared memory, and the data indicates that this shared memory arrangement cannot sustain framerates as pixel counts increase.

The High preset shows the same trend: 71 FPS at 1080p, 51 FPS at 1440p, and 32 FPS at 4K. The reduction from 1080p to 1440p is 28.2%, and from 1440p to 4K it is 37.3%. Ultra settings produce the lowest absolute numbers across the board, with 44 FPS at 1080p, 32 FPS at 1440p, and just 20 FPS at 4K. At every resolution, the gap between Medium and Ultra is substantial, but the gap between 1440p and 4K is consistently larger than the gap between 1080p and 1440p. This nonlinear scaling indicates that the GPU's fill rate and memory subsystem become progressively more strained as resolution grows.

The data suggests that at 1080p, the system still has some headroom in the CPU, but at 1440p and especially 4K, the Intel Arc B390's 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate are simply insufficient to keep up with the demands of Downfall at higher resolutions. The 7.680 TFLOPS FP32 compute rating provides context: this is an integrated-class GPU trying to handle 4K rendering, and the 20 FPS Ultra result at 4K reflects that mismatch.

Settings Recommendations

For players targeting 60 FPS as a playable threshold, the measured data shows that only the Low preset at 1080p achieves this comfortably, with an average of 106 FPS. The Medium preset at 1080p comes close at 87 FPS, and the High preset at 1080p reaches 71 FPS. No other resolution and setting combination in the measured data reaches 60 FPS. At 1440p, the Low preset delivers 76 FPS, which is above the 60 FPS threshold, but Medium drops to 62 FPS and High falls to 51 FPS. At 4K, even Low only manages 47 FPS.

The Medium preset at 1440p provides the best balance of visual quality and performance among the measured rows, with an average of 62 FPS and a minimum of 53 FPS. This is the only 1440p setting that stays within striking distance of 60 FPS while offering improved visuals over Low. The 62 FPS average with a 53 FPS minimum means there will be dips below 60, but the experience remains fluid for most of the run. At 1080p, the High preset at 71 FPS is the recommended choice for those who want better visual fidelity, as it stays well above 60 FPS and provides a more detailed image than Medium.

Ultra settings are not viable at any resolution in this combination. Even at 1080p, Ultra produces only 44 FPS, and at 1440p it drops to 32 FPS. The 4K Ultra result of 20 FPS is effectively unplayable. The gap between High and Ultra at 1080p is 27 FPS (71 to 44), which indicates that Ultra settings impose a heavy penalty that the Intel Arc B390 cannot absorb. Players should avoid Ultra entirely and treat High as the ceiling for this hardware.

For 4K users, the Low preset at 47 FPS is the only option that approaches playability, but even that falls short of 60 FPS. The Medium preset at 4K produces 39 FPS with a minimum of 33 FPS, which may be acceptable for a horror game where slower pacing is common, but it will not feel smooth. The data suggests that 4K gaming on this combination requires significant compromises and is best avoided unless the player can tolerate sub-50 FPS performance.

How This Combo Ranks

The combo ranks 2,589 out of 2,928 tested combinations in Downfall, placing it in the bottom 12% of all systems tested. This low ranking is driven almost entirely by the Intel Arc B390, which sits at the 9th percentile among all GPUs in the database. The CPU, by contrast, is a mid-range performer at the 74th percentile, meaning the processor is not the constraint in this pairing.

To contextualize the GPU's performance: the Arc B390's average benchmark score of 1,482 in 3DMark Steel Nomad DX12 is just 1.3% above the NVIDIA GeForce GT 520MX (1,463), 1.5% above the NVIDIA GeForce 800M (1,460), 2.5% above the NVIDIA GeForce GT 625 OEM (1,446), and 2.7% above the NVIDIA GeForce GT 710 (1,443). These rivals are all entry-level or legacy parts, confirming that the Arc B390 operates in the lowest performance tier of modern GPUs.

The Ryzen 5 5600G, meanwhile, has an average benchmark score of 21,088, which is nearly identical to its nearest rivals: the Intel Core i3-1220P scores 21,066 (0.1% lower), the Intel Core Ultra 7 256V scores 21,112 (0.1% higher), the AMD Ryzen 5 7530U scores 21,133 (0.2% higher), and the Intel Core Ultra 7 155U scores 21,174 (0.4% higher). This CPU is firmly in the mainstream tier, but in Downfall it cannot compensate for the GPU's limitations.

The measured FPS data reinforces this ranking. At 1080p Low, the system produces 106 FPS, which is respectable, but at 4K Ultra it falls to 20 FPS. The spread between best and worst case is 86 FPS, and the system never exceeds 106 FPS at any resolution or setting. For a horror game like Downfall, this ranking suggests that the experience will be acceptable at 1080p with medium-to-high settings, but the hardware is not suited for higher-resolution gaming.

GPU Role

The Intel Arc B390 is an integrated GPU built on the Xe3-LPG architecture using Intel's 3 nm process, with a chip codenamed Panther Lake. Its clocks are listed at a 300 MHz base and a 2,500 MHz boost, and it draws up to 80 W of power. The memory configuration is entirely system-shared, with no dedicated VRAM, no dedicated bus width, and bandwidth described as "System Dependent." This means the GPU relies on the CPU's DDR4 memory, which is dual-channel with a bandwidth of 51.2 GB/s on the Ryzen 5 5600G side.

The GPU's compute specifications are modest: 1,536 shading units, 48 texture mapping units, 24 render output units, and 12 ray tracing cores. Its pixel rate is 60.00 GPixel/s, texture rate is 120.0 GTexel/s, and FP32 performance is 7.680 TFLOPS, with FP16 at 15.36 TFLOPS (2:1). These figures place it in the entry-level segment, and the 9th percentile ranking among all GPUs confirms that assessment.

In Downfall, the GPU's role as the bottleneck is evident from the scaling behavior. The 55% performance drop from 1080p to 4K at both Low and Medium settings indicates that the GPU's fill rate and memory bandwidth are overwhelmed as pixel counts rise. The system-shared memory, which depends on the CPU's DDR4 bandwidth, cannot provide the sustained throughput needed for 4K rendering. The 20 FPS result at 4K Ultra is particularly telling, as it suggests the GPU is completely saturated at that resolution.

The DirectX 12 Ultimate (12_2) support and Vulkan 1.4 compatibility mean the GPU can handle modern rendering features, but the raw performance is insufficient to leverage them at high resolutions. The 12 ray tracing cores provide hardware ray tracing capability, but with only 7.680 TFLOPS of FP32 compute, ray-traced effects would likely cause severe performance degradation. Players using this GPU should stick to rasterized rendering and avoid demanding features.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all settings. Low settings average 106 FPS, Medium averages 87 FPS with a minimum of 74 and a maximum of 100, High averages 71 FPS, and Ultra averages 44 FPS. The gap between Medium and High is 16 FPS, while the gap between High and Ultra is 27 FPS, indicating that Ultra settings impose a disproportionately heavy load on the GPU.

At 2560x1440, performance drops noticeably. Low settings average 76 FPS, Medium averages 62 FPS with a minimum of 53 and a maximum of 71, High averages 51 FPS, and Ultra averages 32 FPS. The Medium preset at 1440p is the only setting in this resolution that stays above 60 FPS on average, but its minimum of 53 FPS means it will dip below that threshold. The High preset drops to 51 FPS, which is a 28.2% reduction from the 71 FPS at 1080p High.

At 3840x2160, the system struggles across the board. Low settings average 47 FPS, Medium averages 39 FPS with a minimum of 33 and a maximum of 44, High averages 32 FPS, and Ultra averages 20 FPS. No 4K setting reaches 60 FPS, and the Ultra result is below 30 FPS, making it effectively unplayable for most users. The Medium preset at 4K has a minimum of 33 FPS, which is just above the threshold where motion becomes visibly stuttery.

The full range of measured results spans from 20 FPS (4K Ultra) to 106 FPS (1080p Low), a difference of 86 FPS. The data shows consistent scaling: each resolution increase from 1080p to 1440p costs roughly 25-30% performance, and each increase from 1440p to 4K costs roughly 35-40% performance. This nonlinear degradation is a hallmark of a GPU that is running out of memory bandwidth and fill rate as pixel count grows.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Cezanne, manufactured on TSMC's 7 nm process. It has a base clock of 3.90 GHz and a boost clock of 4.40 GHz, with 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 DDR4 with a dual-channel bus and 51.2 GB/s bandwidth, and the CPU uses PCIe Gen 3 with 16 lanes.

The CPU's benchmark scores show it is a capable mainstream processor. In Cinebench R23, it scores 10,551 multicore and 1,409 singlecore. In Geekbench, it scores 8,428 multicore and 1,801 singlecore. Its PassMark multithread score is 19,717, and its single-thread score is 3,177. The 3DMark results show scaling from 872 single-thread to 5,455 max-thread, indicating good multi-threaded performance for a 6-core part.

In Downfall, the CPU's role is to feed the GPU with draw calls and game logic, and the data indicates it does this adequately. The fact that frame rates scale so heavily with resolution means the CPU is not the limiting factor; if it were, reducing resolution would not produce such large FPS gains. The Ryzen 5 5600G's 74th percentile ranking places it well above the GPU's 9th percentile, and the measured FPS curve reflects this disparity.

The CPU's nearest rivals are all within 0.4% of its average benchmark score, showing that it is a mid-pack performer. The Intel Core i3-1220P is 0.1% lower, the Intel Core Ultra 7 256V is 0.1% higher, the AMD Ryzen 5 7530U is 0.2% higher, and the Intel Core Ultra 7 155U is 0.4% higher. These differences are negligible in real-world gaming, meaning the 5600G provides consistent, predictable performance that does not bottleneck the Arc B390 in this title.

For players considering this combination, the CPU is not the concern. The 6 cores and 12 threads are sufficient for Downfall, and the 16 MB of L3 cache provides adequate data locality. The real constraint is the GPU, and any upgrade path should focus on replacing the integrated graphics with a discrete solution rather than upgrading the processor. The CPU's headroom in this game is substantial, as evidenced by the 106 FPS at 1080p Low, which is likely near the game's engine limit rather than a hardware ceiling.
