# Overpower with AMD Ryzen 7 5700X3D + Intel Arc B390

The AMD Ryzen 7 5700X3D paired with the Intel Arc B390 delivers playable but constrained performance in Overpower, with the combo ranking 2638th out of 2980 tested configurations. The data shows a system where the integrated graphics solution is the clear bottleneck, while the 8-core CPU provides ample headroom that never becomes the limiting factor at any resolution tested.

Resolution Scaling

The measured FPS data reveals a steep performance cliff as resolution increases, which is the signature of a GPU-bound scenario. At 1920x1080 with Low settings, the combo achieves 72 FPS average, but this drops to 64 FPS at 2560x1440 and further to 54 FPS at 3840x2160 — a total loss of 18 FPS from 1080p to 4K at the same settings. This 25% reduction in frame rate when moving from 1080p to 4K indicates that the rendering pipeline is heavily dependent on the graphics processor's fill rate and memory bandwidth, both of which are constrained on this integrated part.

The scaling pattern becomes more pronounced at higher quality presets. With High settings, the average FPS falls from 42 at 1080p to 37 at 1440p and then to 32 at 4K. That represents a 23.8% drop from 1080p to 4K, similar in proportion to the Low preset's scaling. However, the absolute numbers are significantly lower, suggesting that the GPU is already near its limits even at 1080p High. The Ultra preset shows the same trend: 35 FPS at 1080p, 31 FPS at 1440p, and 26 FPS at 4K, with the 4K result being only 74.3% of the 1080p figure.

What the data makes clear is that resolution scaling is nearly linear in percentage terms across all presets, which is typical of a system where the GPU is saturated at every setting. The CPU is not the constraint here; if it were, we would expect to see a much flatter FPS curve across resolutions, since the Ryzen 7 5700X3D's 8 cores and 16 threads would be able to maintain consistent frame delivery regardless of pixel count. Instead, the consistent 25-30% performance drop from 1080p to 4K across all presets points squarely at the Arc B390's rendering capabilities.

The Medium preset data provides the only min/max FPS readings in the entire measured set, offering additional insight into frame pacing. At 1080p Medium, the average is 45 FPS with a minimum of 38 and maximum of 52, giving a spread of 14 FPS. At 1440p Medium, the average drops to 40 FPS with min/max of 34/46, a 12 FPS spread. At 4K Medium, the average is 34 FPS with min/max of 29/39, an 10 FPS spread. This tightening of the frame time variance at higher resolutions suggests that the GPU is working harder and frame delivery becomes more consistent as it approaches its ceiling, though at the cost of lower average performance.

GPU Role

The Intel Arc B390 is the dominant factor in this combo's Overpower performance, and the numbers make this unambiguous. The GPU's 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, which is exceptionally low for a modern gaming configuration. Its nearest rivals in synthetic benchmarks are the NVIDIA GeForce GT 520MX (scoring 1463, which is 1.3% lower) and the NVIDIA GeForce 800M (1460, 1.5% lower), both of which are ancient entry-level mobile parts. This context is crucial: the Arc B390 is performing in the same league as decade-old integrated and low-end discrete graphics solutions.

The GPU's specifications explain why it struggles. It has 1536 shading units, 48 texture mapping units, and 24 raster output units, with 12 ray tracing cores. Its boost clock is 2500 MHz, but its base clock is just 300 MHz, indicating a wide dynamic range that suggests thermal or power constraints in sustained workloads. The pixel rate is 60.00 GPixel/s and texture rate is 120.0 GTexel/s, with FP32 throughput of 7.680 TFLOPS. These are modest figures for a modern part, and the "System Shared" memory configuration — where the GPU uses system memory rather than dedicated VRAM — is a massive limitation.

The shared memory architecture means bandwidth is "System Dependent," which in this case is the Ryzen 7 5700X3D's dual-channel DDR4 at 51.2 GB/s. This is far below what a dedicated GPU with its own VRAM would offer, and it becomes a critical bottleneck in a game like Overpower that demands high texture bandwidth. The data confirms this: at 4K High, the combo manages only 32 FPS, and at 4K Ultra it falls to 26 FPS. Even at 1080p, the highest settings produce just 35 FPS, which is below the 60 FPS threshold most gamers consider smooth.

The GPU's 80 W TDP and "IGP" slot width indicate this is an integrated solution designed for power efficiency rather than gaming performance. With a 3 nm process node and Xe3-LPG architecture, the Arc B390 is architecturally modern, but its implementation as an integrated GPU severely limits its practical capabilities. The 25% performance drop from 1080p to 4K at Low settings (72 to 54 FPS) is a direct consequence of the shared memory system struggling to feed the GPU with enough data at higher resolutions.

CPU Role

The AMD Ryzen 7 5700X3D is the far more capable half of this pairing, and the benchmark data shows it has substantial headroom in Overpower. This 8-core, 16-thread processor based on Zen 3 architecture (Vermeer codename) runs at a 3.00 GHz base clock and 4.10 GHz boost clock, with a 105 W TDP. Its defining feature is the 96 MB shared L3 cache, which is a massive amount of on-die memory that helps with gaming workloads that exhibit high data locality.

In synthetic benchmarks, the 5700X3D performs admirably. It scores 6764 in 3DMark's 16-thread test and 6755 in the max-threads test, showing near-perfect scaling from 8 to 16 threads. Its Cinebench R23 multicore score of 22366 is strong, and the single-core score of 3157 is respectable. The Geekbench multicore score of 11086 and single-core score of 1849 further confirm that this CPU can handle both lightly-threaded and heavily-threaded workloads effectively.

The CPU's percentile standing of 77th among all processors, with an average benchmark score of 24709, puts it in the upper quartile of all CPUs. Its nearest rivals in average score are the AMD Ryzen 5 7600X3D (24728, which is 0.1% higher) and the AMD Ryzen 9 5900HX (24822, 0.5% higher), while it edges out the Intel Core i5-12450HX (24576, 0.5% lower) and the Intel Core i5-11600 (24563, 0.6% lower). This places the 5700X3D in a tight performance cluster with several other mid-range to high-end parts.

However, the CPU's capabilities are entirely untapped in this game at these settings. The measured FPS data shows no evidence of CPU limitation: if the processor were the bottleneck, we would expect to see FPS remain relatively constant across resolutions at a given settings preset, because the CPU's workload doesn't scale with pixel count. Instead, we see FPS dropping consistently with resolution, which is the hallmark of GPU limitation. The 5700X3D's 8 cores and 16 threads are more than sufficient for Overpower's demands, and the 96 MB L3 cache likely helps maintain consistent frame delivery by reducing memory latency.

The CPU's memory bandwidth of 51.2 GB/s over dual-channel DDR4 is shared with the GPU, which is a compounding factor. While the CPU itself doesn't need all that bandwidth for gaming, the fact that the GPU is drawing from the same pool means neither component can fully utilize the available bandwidth. This is a system-level constraint that affects both components, but it impacts the GPU far more severely.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best experience for this combo. At 1080p, the Low preset delivers 72 FPS average, which is the only configuration in the entire dataset that achieves a truly smooth frame rate. The Medium preset at 1080p drops to 45 FPS, which is playable but noticeably less fluid, while High (42 FPS) and Ultra (35 FPS) fall further into marginal territory.

At 1440p, the Low preset yields 64 FPS, which is still above the 60 FPS threshold and represents the only playable option at this resolution. Medium drops to 40 FPS, High to 37 FPS, and Ultra to 31 FPS. The 4K results are uniformly poor: even Low only manages 54 FPS, with Medium at 34 FPS, High at 32 FPS, and Ultra at 26 FPS.

The recommendation is straightforward: for a smooth experience, the Low preset is the only viable choice, and even then only at 1080p or 1440p. At 1080p Low, the 72 FPS average provides a comfortable margin above the 60 FPS target, and the frame pacing data from the Medium preset (which shows a 14 FPS spread between min and max at 1080p) suggests that Low would be even more consistent. At 1440p Low, the 64 FPS result is still above 60 FPS, making it a viable alternative if the user prefers higher resolution over higher frame rates.

The Medium preset offers a compromise for users who want better visual quality but are willing to accept lower frame rates. At 1080p Medium, the 45 FPS average with a minimum of 38 FPS is playable for slower-paced action, but it falls short of the smoothness most gamers expect. The High and Ultra presets are not recommended at any resolution, as even 1080p High produces just 42 FPS and Ultra drops to 35 FPS.

Notably, the data shows diminishing returns from Low to Medium: at 1080p, the jump from Low to Medium costs 27 FPS (72 to 45), while the jump from Medium to High costs only 3 FPS (45 to 42). This suggests that the Medium preset may be hitting a memory bandwidth ceiling where additional quality settings have less impact on performance. The same pattern appears at 1440p (24 FPS drop from Low to Medium, then 3 FPS from Medium to High) and 4K (20 FPS drop from Low to Medium, then 2 FPS from Medium to High).

How This Combo Ranks

The combo's rank of 2638 out of 2980 tested configurations places it in the bottom 11.5% of all systems tested in Overpower. This is a poor showing, though it's consistent with the GPU's low percentile standing. The Arc B390's 9th percentile rank among all GPUs is the primary driver of this poor performance, while the CPU's 77th percentile standing is effectively wasted in this configuration.

The delta between the CPU's capability and the GPU's limitation is stark. The 5700X3D's average benchmark score of 24709 puts it within 0.5% of the AMD Ryzen 9 5900HX, a high-end mobile processor, and within 0.1% of the Ryzen 5 7600X3D. Yet the combined system's gaming performance in Overpower is dragged down by the GPU to a level that rivals systems with decade-old graphics hardware. This is a textbook case of unbalanced system configuration, where the CPU is overqualified for the GPU's capabilities.

The GPU's nearest rivals in synthetic benchmarks are all NVIDIA parts from the GT 5xx and GT 7xx era, with the GT 710 being the closest at 1443 (2.7% lower than the Arc B390's 1482). These are parts that were low-end when they launched in the early 2010s, and they are completely unsuitable for modern gaming. The fact that the Arc B390 is competing with them in benchmarks, despite being a much newer design on a 3 nm process, underscores how severely the integrated implementation limits its real-world performance.

For context, the combo rank of 2638 means that only 342 tested configurations performed worse in Overpower. The vast majority of systems tested — approximately 88.5% — deliver better frame rates in this game. This places the combo firmly in the "low-end" category for this title, suitable only for users who prioritize portability and power efficiency over gaming performance.
