Lockdown Protocol

The AMD Ryzen 7 5800X paired with the Intel Arc B370 produces a highly constrained gaming experience in Lockdown Protocol, particularly at higher resolutions. Benchmark data indicates that while the CPU provides substantial processing headroom, the GPU becomes the definitive bottleneck, limiting performance to levels well below playable thresholds outside of specific low-resolution configurations. The following analysis breaks down the measured performance, component roles, and contextual ranking of this combination.

Resolution Scaling

The measured FPS data reveals a predictable but severe decline in performance as resolution increases, confirming that the Intel Arc B370 is the primary limiting factor. At 1080p with Low settings, the combo achieves an average of 80 FPS. Moving to 1440p at the same settings drops the average to 58 FPS, a reduction of 27.5%. At 4K, the average falls further to 38 FPS, representing a 52.5% decrease from the 1080p baseline. This scaling pattern is characteristic of a GPU that is being saturated by pixel throughput demands.

The trend becomes more pronounced at higher quality presets. At High settings, the average frame rate drops from 49 FPS at 1080p to 36 FPS at 1440p (a 26.5% decrease) and then to 23 FPS at 4K (a 53.1% decrease from 1080p). The incremental cost of resolution is consistent across settings, suggesting that the GPU's shading units and ROPs are entirely consumed by the increasing pixel count, with no headroom left for the CPU to influence the outcome.

The data indicates that the CPU is not a factor in this scaling. The Ryzen 7 5800X, with its 8 cores and 16 threads, is more than capable of feeding frames to a GPU of this class. The measured FPS drops are almost perfectly proportional to the increase in pixel count, which is a classic symptom of a pixel-bound scenario. The transition from 1080p to 1440p costs roughly a quarter of the performance, and the transition to 4K costs roughly half, aligning with the mathematical increase in pixels. This is not a case where the CPU's frame generation limits are being reached; rather, the GPU's render output units are the clear constraint.

CPU Role

The AMD Ryzen 7 5800X is a Zen 3 architecture processor codenamed Vermeer, built on a 7 nm process by TSMC. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a 32 MB L3 cache. The processor supports DDR4 memory over a dual-channel bus, with a theoretical bandwidth of 51.2 GB/s. It connects via PCIe Gen 4 with 20 lanes.

In the context of Lockdown Protocol, the CPU's role is to prepare and submit draw calls, handle game logic, and manage the simulation of the FPS world. The data shows that even at 1080p Low, where the CPU experiences the least GPU-related waiting time, the average FPS is 80. This is a modest figure for a processor of this caliber. The CPU's benchmark scores reflect its strong multi-threaded and single-threaded capabilities. For instance, it scores 15,476 in Cinebench R23 multi-core and 1,574.5 in single-core. Its Passmark multi-thread score is 27,732, and its single-thread score is 3,445.

These scores suggest the CPU is not the bottleneck. The 3DMark 16-thread score of 7,586 and the 2-thread score of 1,846 further indicate a balanced performance profile. However, the game's measured FPS is far lower than what these scores would imply if the CPU were the limiting factor. With a percentile ranking of 81 among all CPUs, this processor is well above average. The nearest rivals include the Intel Core Ultra 5 135H with a deltaPct of 0.1% and the AMD Ryzen 5 5600XT with a deltaPct of 0.6%, showing the 5800X is competitive but not exceptional. The data strongly suggests that the CPU is idle waiting for the GPU to complete its work, making the processor's clock speed and core count largely irrelevant to the final frame rate in this specific configuration.

GPU Role

The Intel Arc B370 is a mobile-class integrated graphics processor from the Arc Graphics-M generation, based on the Panther Lake chip and Xe3-LPG architecture. It is built on a 3 nm process by Intel. The GPU has a base clock of 300 MHz and a boost clock of 2400 MHz. It features 1280 shading units, 40 texture mapping units, and 20 render output units. It also includes 10 ray tracing cores. The pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s, with FP32 performance rated at 6.144 TFLOPS.

The GPU's memory configuration is listed as "System Shared," meaning it relies on the host system's DDR4 memory rather than dedicated VRAM. Its bandwidth is described as "System Dependent," which implies that performance can vary based on the system's memory configuration. The TDP is a very low 25 W, and it is an IGP (Integrated Graphics Processor) with no power connectors. This GPU's sole benchmark score is 1,184 in 3DMark Steel Nomad DX12, placing it in the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 and the ATI Radeon HD 5770, with deltaPct values of -0.2% and -0.5% respectively.

In Lockdown Protocol, the GPU's limitations are starkly evident. The measured FPS at 4K Ultra is 18, which is effectively unplayable. Even at 1080p High, the average FPS is only 49. The low ROP count and pixel rate directly translate to the resolution scaling issues seen previously. The GPU is unable to sustain high fill rates, and the lack of dedicated VRAM likely exacerbates texture filtering and memory access latency issues at higher settings. The data shows that the GPU is the sole performance limiter in this combo, with its capabilities being exhausted long before the CPU can demonstrate its potential.

FAQ

Q: What is the best resolution for this combo to achieve playable frame rates?

A: The data shows that 1080p is the only resolution where average frame rates exceed 60 FPS, and only at Low settings (80 FPS). At 1440p and 4K, all settings produce average frame rates below 60 FPS.

Q: How does the GPU compare to its nearest rivals?

A: The Intel Arc B370 has an average benchmark score of 1,184, which is nearly identical to the ATI Mobility Radeon HD 5570 (score 1,186, deltaPct -0.2%) and the ATI Radeon HD 5770 (score 1,190, deltaPct -0.5%). This indicates it is on par with these older, low-end parts.

Q: Does the CPU's performance matter in this game?

A: Benchmark results indicate no. The CPU has a strong multi-thread score of 15,476 in Cinebench R23 and a high percentile ranking of 81, yet FPS is limited by the GPU at all tested resolutions, showing the CPU has significant idle headroom.

Q: What is the performance difference between Low and Ultra settings at 1080p?

A: At 1080p, the average FPS drops from 80 on Low to 37 on Ultra. This represents a 53.75% decrease in performance when moving to the highest quality preset.

Q: Is the frame rate stable at 1440p Medium?

A: The data shows an average of 42 FPS with a minimum of 35 FPS and a maximum of 48 FPS. This indicates a variance of 13 FPS, which is relatively narrow and suggests a consistent, albeit low, performance level.

Q: How does this combo rank against all tested combinations?

A: The combo ranks 2,611 out of 2,828 tested combos in Lockdown Protocol. This places it in the bottom 8% of all configurations, indicating a very low overall performance level.

How This Combo Ranks

The combo's rank in Lockdown Protocol is 2,611 out of 2,828 tested combinations. This places it in the 7.7th percentile of all tested systems, meaning it outperforms only a small fraction of the database. This ranking is heavily influenced by the GPU's low performance ceiling. The Intel Arc B370's 5th percentile ranking among all GPUs is the primary driver of this poor overall position.

The CPU's high ranking (81st percentile) does little to improve the combo's standing, as it is never the limiting component. The data suggests that the CPU could drive a much more powerful GPU to significantly higher frame rates, but in this pairing, its potential is entirely untapped. The deltaPct values for the GPU's rivals, such as the ATI Radeon HD 5770 (-0.5%), show that the B370 is essentially at the bottom of the performance barrel for discrete-class parts, despite being a modern integrated solution. The combo rank accurately reflects the sum of these parts: a powerful CPU wasted on a very weak GPU.

Settings Recommendations

Based on the measured FPS data, the only viable setting for a consistently smooth experience is 1080p with Low settings, which yields an average of 80 FPS. This is the only tested configuration that exceeds the 60 FPS threshold, which is often considered the baseline for fluid gameplay in an FPS. All other settings at 1080p fall below this mark, with Medium at 57 FPS, High at 49 FPS, and Ultra at 37 FPS.

For users who prioritize visual fidelity over frame rate, 1080p Medium is a compromise, offering a 57 FPS average with a minimum of 48 FPS. However, the drop to High (49 FPS) and Ultra (37 FPS) is substantial, and the visual gains may not justify the performance loss. At 1440p, the best average FPS is 58 on Low, but this is still below the 60 FPS target. At 4K, even Low settings only reach 38 FPS, making this resolution unsuitable for this hardware. The data clearly indicates that 1080p Low is the only setting that provides a playable experience, and anything higher will result in noticeable frame rate drops.

Measured FPS Breakdown

The following table details the exact average FPS measured for each resolution and settings combination:

• 1920x1080 (1080p):
• Low: 80 FPS average
• Medium: 57 FPS average (min 48, max 65)
• High: 49 FPS average
• Ultra: 37 FPS average

• 2560x1440 (1440p):
• Low: 58 FPS average
• Medium: 42 FPS average (min 35, max 48)
• High: 36 FPS average
• Ultra: 27 FPS average

• 3840x2160 (4K):
• Low: 38 FPS average
• Medium: 27 FPS average (min 23, max 31)
• High: 23 FPS average
• Ultra: 18 FPS average

The data shows a consistent pattern: each step up in resolution costs approximately 25-30% of the frame rate, and each step up in quality costs a similar amount. The minimum FPS figures, where available, show that the frame pacing remains relatively stable, with no major stutters, but the overall performance is too low for competitive or immersive play at higher settings. The 1080p Low configuration is the only one that delivers a frame rate high enough for a responsive FPS experience.
