Lockdown Protocol

# Lockdown Protocol with AMD Ryzen 7 5800X3D + Intel Arc B390

The AMD Ryzen 7 5800X3D paired with the Intel Arc B390 is a combination that sits at the bottom of the performance ladder for Lockdown Protocol, ranking 2512th out of 2828 tested combos. The data shows a system where the GPU is the clear bottleneck, and the results are best understood as a study in what happens when a modern integrated graphics solution is asked to run a demanding FPS title at increasingly heavy resolutions and settings.

Resolution Scaling

The FPS progression across resolutions reveals a GPU that is heavily taxed at every step. At 1080p with Low settings, the combo manages 88 FPS average. Moving to 1440p Low drops that to 65 FPS, a 26% reduction. At 4K Low, the average falls to 42 FPS, which is roughly 52% below the 1080p Low result. This steep decline as pixel count rises is the classic signature of a graphics-bound scenario — the Ryzen 7 5800X3D has more than enough headroom to feed frames, but the Arc B390 cannot keep up with the increasing fill-rate demands.

The scaling pattern holds across all settings. At Medium, 1080p yields 63 FPS, 1440p yields 46 FPS, and 4K yields 30 FPS. The drop from 1080p to 1440p is about 27%, and from 1080p to 4K it is about 52%. At High settings, the numbers are 55 FPS at 1080p, 40 FPS at 1440p, and 26 FPS at 4K — again a consistent halving of performance from 1080p to 4K. Ultra settings show the same trend: 41 FPS at 1080p, 30 FPS at 1440p, and 19 FPS at 4K.

What this scaling tells a builder is that the limiting component is unambiguously the GPU. The CPU, with its 8 cores and 16 threads, is not the factor dragging performance down when resolution increases. If the processor were the bottleneck, we would expect to see much flatter FPS numbers across resolutions, particularly at lower settings where CPU work dominates. Instead, every resolution step produces a proportional FPS hit, which is the hallmark of a GPU that is saturated even at 1080p. The practical takeaway: this combo is only viable for 1080p play, and even then, only at Low or Medium settings if you want a playable frame rate. At 4K, every setting produces averages below 42 FPS, with Ultra dropping to 19 FPS, which is effectively unplayable for a fast-paced FPS.

How This Combo Ranks

With a combo rank of 2512 out of 2828 tested combinations, this pairing sits in the bottom 11% of all tested systems for Lockdown Protocol. That is a low position, but it is important to contextualize it. The rank reflects the combined performance of both components, and the data indicates that the Intel Arc B390 is dragging the system down far more than the AMD processor is helping it up.

The GPU's percentile versus all GPUs is just 9, meaning it performs better than only 9% of all GPUs in the database. Its nearest rivals in the benchmark database are the NVIDIA GeForce GT 520MX, GeForce 800M, GeForce GT 625 OEM, and GeForce GT 710 — all with scores within 2.7% of the Arc B390. Those are legacy integrated or entry-level parts from years ago, which puts the Arc B390's performance class in perspective. In fact, the Arc B390 is only 1.3% ahead of the GT 520MX and 2.7% ahead of the GT 710, so it is barely faster than those ancient parts in raw compute.

The CPU, by contrast, is in the 80th percentile versus all CPUs. Its nearest rivals include the AMD Ryzen 7 6800U, Intel Core i9-10900K, AMD Ryzen AI 5 PRO 340, and Intel Core i5-12600KF, with deltaPct values ranging from -0.1% to +0.3%. That puts the Ryzen 7 5800X3D essentially on par with the Core i9-10900K and i5-12600KF in overall CPU benchmark scores, which is a strong showing for a processor that is now end-of-life. The combination of a top-tier CPU and a bottom-tier GPU creates a massive imbalance, and the combo rank reflects that. If you were to swap the GPU for something in the mid-range, this same CPU would likely push the combo rank much higher, but as tested, the system is held back almost entirely by the graphics solution.

GPU Role

The Intel Arc B390 is an integrated graphics processor built on the Xe3-LPG architecture, using the Panther Lake chip on a 3 nm process. It has 1536 shading units, 48 texture mapping units, and 24 raster operation units, along with 12 ray tracing cores. The base clock is 300 MHz, boosting to 2500 MHz. Its memory configuration is entirely system shared — there is no dedicated VRAM, no dedicated memory bus width, and the bandwidth is listed as system dependent. The FP32 compute is 7.680 TFLOPS, which is a modest figure for a modern GPU, and its pixel rate is 60.00 GPixel/s with a texture rate of 120.0 GTexel/s.

The lack of dedicated VRAM is a critical factor in this game's results. Lockdown Protocol, as a modern FPS, needs to stream textures and geometry, and with system shared memory, the GPU is competing with the CPU for bandwidth. The measured data shows the consequences: at 1080p High, the average FPS is 55, but at 1080p Ultra, it drops to 41. That 25% performance hit from High to Ultra is larger than what you would typically see on a discrete GPU, where the overhead of higher settings is more about shading complexity than memory bandwidth. Here, the system shared memory is likely causing additional latency and bandwidth contention, which manifests as a steeper performance cliff at higher settings.

The GPU's benchmark score in 3DMark Steel Nomad DX12 is 1482, which places it in the 9th percentile. Its nearest rivals are all NVIDIA parts from over a decade ago, and the deltaPct values show the Arc B390 is only marginally faster — 1.3% over the GT 520MX and 2.7% over the GT 710. This is not a GPU that can handle modern gaming at high fidelity. The data shows it struggles to maintain 60 FPS even at 1080p Low, and at 4K it cannot break 42 FPS in any setting. For Lockdown Protocol specifically, the GPU is the limiting factor at every resolution and settings combination tested.

Measured FPS Breakdown

At 1920x1080, the lowest resolution tested, the results are mixed. Low settings produce an average of 88 FPS, which is the only configuration in the entire dataset that approaches a comfortable range for competitive FPS play. Medium settings drop to 63 FPS, with a minimum of 53 and a maximum of 72. High settings average 55 FPS, and Ultra settings average 41 FPS. The spread from Low to Ultra is 47 FPS, which is a wide gap and indicates that the GPU's performance is highly sensitive to settings changes at this resolution. For a 1080p monitor, Low settings are the only way to get a smooth 144 Hz experience, while Medium and High are playable on a 60 Hz display.

At 2560x1440, the performance drops significantly. Low settings average 65 FPS, which is still playable but far from the 88 FPS seen at 1080p. Medium settings average 46 FPS with a minimum of 39 and a maximum of 53. High settings average 40 FPS, and Ultra settings average 30 FPS. The pattern here is consistent: each settings tier costs roughly 15-20 FPS, and even Low settings cannot maintain a solid 60 FPS in all scenes given the 65 FPS average. For 1440p, this combo is only suitable for Low settings, and even then, you will see dips below 60 FPS in demanding moments.

At 3840x2160, the results are poor across the board. Low settings average 42 FPS, Medium settings average 30 FPS with a minimum of 25 and a maximum of 34, High settings average 26 FPS, and Ultra settings average 19 FPS. No setting at 4K produces a playable frame rate for a shooter. The minimum FPS of 25 at Medium settings highlights the inconsistency — even the averages are low, but the dips make it worse. The 4K data strongly suggests this resolution is out of reach for the Arc B390 in this game, regardless of settings.

The measured data is complete for all 12 combinations of resolution and settings, with only the Medium settings at each resolution providing min and max FPS values. The averages tell a clear story: this is a 1080p Low-to-Medium system at best, and it falls apart at higher resolutions.

FAQ

Q: What is the best settings and resolution combination for this system?

A: The data shows that 1920x1080 with Low settings is the only configuration that breaks 60 FPS, averaging 88 FPS. If you need 60 FPS as a baseline, 1440p Low at 65 FPS is the next best option, but it will dip below 60 in some scenes.

Q: Can this combo handle 4K gaming in Lockdown Protocol?

A: No. At 4K, even Low settings only produce an average of 42 FPS, and Ultra drops to 19 FPS. The minimum FPS at 4K Medium is 25, which is well below playable for a fast-paced FPS.

Q: How does the Intel Arc B390 compare to its nearest rivals?

A: The Arc B390 is only 1.3% faster than the NVIDIA GeForce GT 520MX and 2.7% faster than the NVIDIA GeForce GT 710 in average benchmark scores. It is essentially at the bottom of the GPU performance pool, sitting in the 9th percentile.

Q: Is the AMD Ryzen 7 5800X3D a bottleneck in this combination?

A: No. The CPU is in the 80th percentile and performs within 0.3% of the Intel Core i9-10900K and i5-12600KF. The FPS scaling across resolutions shows the GPU is the limiting factor, not the processor.

Q: What kind of frame rate can I expect at 1080p with High settings?

A: The average FPS is 55, which is playable on a 60 Hz monitor but will not be smooth on a 144 Hz display. For higher refresh rates, you would need to drop to Low settings.

Q: How much performance do I lose by going from 1080p to 4K at the same settings?

A: At Low settings, the average FPS drops from 88 at 1080p to 42 at 4K, a 52% reduction. At High settings, it drops from 55 to 26, also roughly 53%. The scaling is consistent, confirming the GPU is the bottleneck.

CPU Role

The AMD Ryzen 7 5800X3D is a desktop processor from the 5000 series, built on the Zen 3 architecture with the Vermeer codename. It has 8 cores and 16 threads, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. The L3 cache is 96 MB shared, which is the defining feature of this chip — the large cache is designed to improve gaming performance by reducing memory latency. It supports DDR4 memory in a dual-channel configuration with a bandwidth of 51.2 GB/s, and it uses the AMD Socket AM4. The CPU's TDP is 105 watts, and it was released in April 2022 with a launch MSRP of $449.

In the benchmark database, the Ryzen 7 5800X3D holds the 80th percentile versus all CPUs, with an average benchmark score of 27896. Its nearest rivals are a mix of mobile and desktop parts: the AMD Ryzen 7 6800U scores 27887 (0% delta), the Intel Core i9-10900K scores 27872 (0.1% delta), the AMD Ryzen AI 5 PRO 340 scores 27932 (-0.1% delta), and the Intel Core i5-12600KF scores 27799 (0.3% delta). This puts the 5800X3D in the same performance class as the i9-10900K, which is a 10-core, 20-thread desktop chip — a strong showing for the 8-core AMD part.

For Lockdown Protocol, the CPU's role is to feed frames to the GPU, and the data shows it does that job capably. The resolution scaling pattern, where FPS drops proportionally with pixel count, indicates the CPU is not the limiting factor. If the CPU were the bottleneck, we would see the 1080p and 1440p results converge, since both would be capped by the processor's frame generation limit. Instead, the 1080p Low result of 88 FPS vs. the 4K Low result of 42 FPS shows a clear GPU-driven decline. The 5800X3D's 96 MB L3 cache likely helps maintain consistent frame pacing, but the GPU is too weak to benefit from it meaningfully. In a better-balanced system, this CPU would be a strong performer for Lockdown Protocol, but with the Arc B390, its capabilities are largely wasted.
