Lockdown Protocol

# How This Combo Ranks

The AMD Ryzen 5 7400F paired with the Intel Arc B390 ranks 2512th out of 2828 tested combinations in Lockdown Protocol. This places the combo in the bottom 11% of all tested pairings, a position driven almost entirely by the GPU's limitations rather than the CPU's capabilities. The data shows a substantial mismatch between the processor's strong synthetic showing and the graphics solution's ability to translate that into frame rate.

Benchmark results indicate the Arc B390 sits at the 9th percentile among all GPUs, with an average 3DMark Steel Nomad DX12 score of 1482. Its nearest rivals in synthetic testing are the NVIDIA GeForce GT 520MX, GeForce 800M, GeForce GT 625 OEM, and GeForce GT 710, with delta percentages of 1.3%, 1.5%, 2.5%, and 2.7% respectively. These are all legacy or entry-level mobile parts, which contextualizes just how far down the performance ladder this integrated graphics solution falls.

By contrast, the Ryzen 5 7400F ranks in the 83rd percentile among all CPUs, with an average benchmark score of 32750. Its nearest rivals include the Intel Core i5-14600T (delta 0.1%), Intel Core Ultra 7 155H (delta 0.2%), AMD Ryzen 7 PRO 6850H (delta -0.2%), and AMD Ryzen AI 7 PRO 360 (delta 0.3%). The CPU is essentially neck-and-neck with these parts, all within a third of a percent of each other. This means the processor is performing at a level consistent with mid-range desktop and high-end mobile chips from recent generations, while the GPU is performing at levels associated with decade-old discrete solutions.

The combination's overall rank suggests that in Lockdown Protocol, the frame rate ceiling is determined by the graphics subsystem. The CPU could handle significantly more graphics headroom if paired with a more capable GPU. The 2512th position out of 2828 combos is not a reflection of CPU weakness, but rather a direct consequence of the Arc B390's position as an integrated part with limited shading resources.

GPU Role

The Intel Arc B390 is built on Intel's Xe3-LPG architecture, fabricated on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The memory configuration is entirely system-shared, meaning there is no dedicated VRAM; the GPU draws from the same DDR5 memory pool as the CPU. Memory bandwidth is listed as system-dependent, which introduces variability in performance based on the host platform's memory configuration.

The GPU contains 1536 shading units, 48 texture mapping units, and 24 raster output units. It also includes 12 ray tracing cores. The pixel rate is 60.00 GPixel/s, and the texture rate is 120.0 GTexel/s. Floating point performance is rated at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16 (2:1 ratio). The power envelope is 80 W, and the slot width is listed as IGP, confirming its integrated nature.

In Lockdown Protocol, the GPU's modest shading resources directly cap performance. At 1080p Low, the combo produces 88 FPS, but this drops to 41 FPS at 1080p Ultra — a 53% reduction when moving from the lowest to highest quality preset. The pattern is consistent across resolutions. At 1440p, Low yields 65 FPS while Ultra yields 30 FPS. At 4K, Low produces 42 FPS while Ultra drops to 19 FPS.

The lack of dedicated VRAM means the system-shared memory bandwidth becomes a bottleneck at higher resolutions and settings. The 3DMark Steel Nomad score of 1482 places this GPU in company with parts like the GT 520MX and GT 710, which were designed for basic display output rather than gaming. The data suggests that the Arc B390's role in this pairing is fundamentally constrained by its integrated design and shared memory architecture.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four quality presets (Low, Medium, High, Ultra). All results are average FPS unless otherwise noted.

At 1920x1080, the Low preset delivers 88 FPS. Medium produces 63 FPS, with a minimum of 53 FPS and a maximum of 72 FPS. High delivers 55 FPS. Ultra produces 41 FPS. The spread from Low to Ultra is 47 FPS, representing a 53.4% reduction in average frame rate.

At 2560x1440, Low delivers 65 FPS. Medium produces 46 FPS, with a minimum of 39 FPS and a maximum of 53 FPS. High delivers 40 FPS. Ultra produces 30 FPS. The spread from Low to Ultra is 35 FPS, representing a 53.8% reduction.

At 3840x2160, Low delivers 42 FPS. Medium produces 30 FPS, with a minimum of 25 FPS and a maximum of 34 FPS. High delivers 26 FPS. Ultra produces 19 FPS. The spread from Low to Ultra is 23 FPS, representing a 54.8% reduction.

The Medium preset is the only one that includes minimum and maximum FPS data across all three resolutions. At 1080p Medium, the range is 53 to 72 FPS. At 1440p Medium, the range is 39 to 53 FPS. At 4K Medium, the range is 25 to 34 FPS. The minimum FPS values indicate that frame pacing becomes increasingly inconsistent as resolution rises.

Resolution Scaling

The transition from 1080p to 4K reveals the GPU's scaling behavior under increasing pixel throughput demands. At Low settings, the average FPS drops from 88 at 1080p to 65 at 1440p, then to 42 at 4K. This represents a 26.1% drop from 1080p to 1440p, and a 35.4% drop from 1440p to 4K. The cumulative drop from 1080p to 4K is 52.3%.

At Medium settings, the numbers are 63 FPS at 1080p, 46 FPS at 1440p, and 30 FPS at 4K. The drop from 1080p to 1440p is 27.0%, and from 1440p to 4K is 34.8%. The cumulative drop is 52.4%.

At High settings, the averages are 55 FPS at 1080p, 40 FPS at 1440p, and 26 FPS at 4K. The drop from 1080p to 1440p is 27.3%, and from 1440p to 4K is 35.0%. The cumulative drop is 52.7%.

At Ultra settings, the averages are 41 FPS at 1080p, 30 FPS at 1440p, and 19 FPS at 4K. The drop from 1080p to 1440p is 26.8%, and from 1440p to 4K is 36.7%. The cumulative drop is 53.7%.

The relative consistency of these percentage drops across all four settings presets is notable. The scaling pattern suggests that the limiting component is the GPU's raw pixel throughput, not memory bandwidth or CPU-side factors. The Arc B390's system-shared memory architecture means that as resolution increases, the competition for memory bandwidth between CPU and GPU intensifies, but the proportional FPS drops remain stable. This indicates a fill-rate-limited scenario where the GPU's 24 ROPs and 60.00 GPixel/s pixel rate are the primary constraints at higher resolutions.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. It operates on the AMD Socket AM5 platform with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The TDP is 65 W. The CPU is fabricated on TSMC's 5 nm process with 6,570 million transistors on a 71 mm² die.

The cache hierarchy includes 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. Memory support is DDR5 with a dual-channel bus, providing 83.2 GB/s of memory bandwidth. The CPU supports ECC memory and offers PCIe Gen 5 with 24 lanes (CPU only). It has no integrated graphics.

Synthetic benchmarks show a single-thread score of 3072 in Cinebench R23, and a multi-core score of 21765 in the same test. Passmark results include a multi-thread score of 25645, a single-thread score of 3689, and a physics score of 1660. The CPU's average benchmark score of 32750 places it at the 83rd percentile among all CPUs.

In Lockdown Protocol, the CPU's role is to feed the GPU with frame data. The benchmark results indicate that the Ryzen 5 7400F is more than sufficient for this task, given that the measured FPS is consistently low across all settings. The CPU's 12 threads and high boost clock of 4.70 GHz provide ample headroom for game logic and physics simulation. The Passmark physics score of 1660 suggests that CPU-side physics processing is not a bottleneck at any tested configuration.

The launch MSRP for this CPU is $229.

Settings Recommendations

Based on the measured FPS data, the optimal configuration for Lockdown Protocol with this combo depends on the target resolution and acceptable frame rate floor.

At 1920x1080, the Low preset delivers 88 FPS, which is the only configuration that provides a substantial margin above the 60 FPS threshold. The Medium preset at 63 FPS also maintains playability, but the minimum FPS of 53 suggests occasional dips below 60. For competitive play where frame rate consistency matters, Low is the recommended preset at 1080p. For a more visually refined experience, Medium offers a reasonable compromise, though the 53 FPS minimum may be noticeable in fast-paced FPS action.

At 2560x1440, Low delivers 65 FPS, which is above the 60 FPS threshold but with less margin than at 1080p. The Medium preset at 46 FPS is playable but below the smoothness threshold. Given the GPU's integrated nature and the 9th percentile performance ranking, Low is the only viable preset at 1440p for maintaining playable frame rates. The High preset at 40 FPS and Ultra at 30 FPS are not recommended for this title.

At 3840x2160, no preset achieves 60 FPS. The Low preset at 42 FPS is the highest average, but it still falls short of smooth gameplay standards. The Medium preset at 30 FPS with a minimum of 25 FPS is marginal at best. The High preset at 26 FPS and Ultra at 19 FPS are effectively unplayable for a fast-paced FPS. The data suggests that 4K gaming is not a viable option with this combo in Lockdown Protocol.

The broad recommendation is to target 1080p with Medium settings as the baseline experience, offering 63 FPS average with a 53 FPS minimum. Players prioritizing frame rate consistency should select Low at 1080p for 88 FPS. For those who must play at 1440p, Low is the only sensible choice. The Ultra preset should be avoided entirely at all resolutions, as it delivers the lowest FPS values across the board, with a maximum of 41 FPS even at 1080p.
