Overpower

The AMD Ryzen 5 5600GT paired with the Intel Arc B390 presents a curious case in the Overpower benchmark database. This combination sits at rank 2638 out of 2980 tested combos, placing it in the lower percentile of systems, yet the measured frame rates reveal a nuanced story about which component is holding the experience back. The data shows a 6-core, 12-thread Zen 3 processor driving an integrated-class GPU with 1536 shading units, and the interaction between these two elements defines every result in the table.

Resolution Scaling

The FPS drop from 1080p to 4K is the single most telling metric in this dataset. At 1920x1080 with Low settings, the combo produces 72 FPS average. Moving to 2560x1440 at the same settings drops that to 64 FPS, a reduction of 8 FPS or roughly 11%. Jumping to 3840x2160 at Low settings yields 54 FPS, which is another 10 FPS decline from the 1440p figure. This scaling pattern — 72 to 64 to 54 as resolution climbs — suggests the GPU is the primary limiter, as the frame rate decreases steadily with pixel count rather than plateauing, which would indicate a CPU bottleneck.

The Medium settings row amplifies this observation. At 1080p Medium, the average is 45 FPS, which falls to 40 FPS at 1440p and then to 34 FPS at 4K. The proportional drops are consistent: each resolution step costs roughly 5-6 FPS. This linear degradation is characteristic of a system where the graphics processor is saturated at every resolution, because if the CPU were the bottleneck, we would expect the frame rate to remain relatively flat when lowering resolution, since the CPU workload would stay similar. Instead, the FPS scales almost directly with the number of pixels rendered.

High settings tell a similar story but with a tighter spread. The 1080p High average is 42 FPS, 1440p High drops to 37 FPS, and 4K High lands at 32 FPS. The difference between 1080p and 4K here is only 10 FPS, compared to 18 FPS on Low settings. This narrowing gap at higher visual fidelity might suggest that the GPU is struggling more uniformly across resolutions when the shader load increases, making the pixel count less of a differentiator. However, the fact that 4K Ultra produces only 26 FPS while 1080p Ultra produces 35 FPS — a 9 FPS difference — reinforces that resolution scaling remains a consistent penalty.

What does this imply about the limiting component? The Intel Arc B390 has a boost clock of 2500 MHz and a base clock of 300 MHz, with a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. These numbers suggest a very low-end integrated GPU, and the measured behavior aligns perfectly. If the Ryzen 5 5600GT were the constraint, we would see less variance between resolutions because the CPU’s 3.60 GHz base and 4.60 GHz boost clocks would cap the frame rate regardless of pixel count. Instead, the steady erosion of FPS as resolution increases points squarely at the GPU’s fill rate limits.

GPU Role

The Intel Arc B390 is classified as an IGP (integrated graphics processor) with system-shared memory, meaning it has no dedicated VRAM of its own. The memory bus width is listed as “System Shared” and bandwidth as “System Dependent,” which is a critical detail for Overpower’s performance profile. This architecture shares the system’s DDR4 memory with the CPU, and the Ryzen 5 5600GT supports dual-channel memory with a bandwidth of 51.2 GB/s. That shared bandwidth becomes a contention point in games, as both the CPU and GPU compete for the same memory controller.

The GPU’s benchmark data shows a 3DMark Steel Nomad DX12 score of 1482, with a percentile ranking of 9 against all GPUs. This places it in the bottom decile, and its nearest rivals are all NVIDIA parts from a much older era: the GeForce GT 520MX scores 1463 (1.3% behind), the GeForce 800M scores 1460 (1.5% behind), the GeForce GT 625 OEM scores 1446 (2.5% behind), and the GeForce GT 710 scores 1443 (2.7% behind). This comparison is stark — the Arc B390 is roughly on par with entry-level GPUs from over a decade ago, which explains why Overpower’s frame rates hover in the 30-70 FPS range depending on settings.

The GPU’s shading units number 1536, with 48 texture mapping units and 24 raster output units. The FP32 performance is 7.680 TFLOPS, and FP16 is 15.36 TFLOPS with a 2:1 ratio. These raw compute figures sound substantial on paper, but the integrated nature and shared memory bottleneck undermine the real-world throughput. In Overpower, the frame rates at 4K Ultra (26 FPS) and even 1080p Ultra (35 FPS) demonstrate that the GPU cannot sustain high settings at any resolution, regardless of the CPU’s capabilities.

Another factor is the 80 W TDP for the GPU, which is notably low even for an integrated part. This power envelope constrains the clock speeds and voltage, and the boost clock of 2500 MHz might not be sustainable under sustained gaming loads. The measured FPS values likely reflect average sustained performance rather than peak bursts, and the lack of min/max FPS data for most rows (only Medium settings include min and max values) makes it harder to assess frame pacing. For Medium at 1080p, the min is 38 FPS and max is 52 FPS, which shows a 14 FPS range — indicating that the GPU’s output is not stable under load.

FAQ

Q: Why does the frame rate drop so much from 1080p to 4K?

A: The measured data shows the average FPS falling from 72 at 1080p Low to 54 at 4K Low, and from 45 at 1080p Medium to 34 at 4K Medium. This consistent decline across all settings indicates the Intel Arc B390’s rendering capabilities are the limiting factor, as its pixel rate of 60.00 GPixel/s is too low to maintain higher frame rates when pixel count increases.

Q: Is the Ryzen 5 5600GT CPU strong enough for this game?

A: The CPU benchmarks suggest it has ample compute headroom. The Ryzen 5 5600GT scores 17272 in Cinebench R23 multicore and 2438 in single-core, with a 3DMark max threads score of 5554. Given that the GPU ranks in the 9th percentile while the CPU ranks in the 74th percentile, the processor is not the bottleneck in Overpower.

Q: What settings should be used for the best playable experience?

A: Based on the measured rows, Low settings at 1080p produces 72 FPS, which is the highest average frame rate in the dataset. Medium settings at 1080p yields 45 FPS, which is still playable but represents a 37.5% drop from Low. For 1440p, Low settings at 64 FPS is the only option above 60 FPS.

Q: How does the Arc B390 compare to other GPUs in the database?

A: The GPU’s 3DMark score of 1482 places it below the NVIDIA GeForce GT 520MX, which scores 1463 but has a deltaPct of 1.3% meaning the Arc B390 is 1.3% faster. However, the GT 520MX is a very old entry-level mobile part, so this comparison highlights how weak the Arc B390 is by modern standards.

Q: Does the shared memory configuration hurt performance?

A: The GPU uses system-shared memory with a bus width and bandwidth both listed as “System Shared” and “System Dependent.” This means it relies on the CPU’s DDR4 memory, which is dual-channel with 51.2 GB/s bandwidth. This shared arrangement likely causes contention and explains why frame times are inconsistent, as seen with the Medium settings min/max spread.

Q: What is the combo’s overall ranking in Overpower?

A: The combo ranks 2638 out of 2980 tested combinations, placing it in the bottom 11.5% of systems. This ranking is consistent with the GPU’s low percentile score and the measured frame rates, which struggle to reach 60 FPS at most settings.

Measured FPS Breakdown

At 1920x1080, the lowest resolution tested, the combo produces its best results. Low settings yield an average of 72 FPS, which is the only setting that breaks the 60 FPS threshold. Medium settings drop to 45 FPS average with a minimum of 38 and maximum of 52 FPS, showing a 14 FPS variance that indicates frame pacing issues. High settings average 42 FPS, and Ultra settings average 35 FPS. The gap between Low and Ultra is 37 FPS, which is a 51.4% reduction — a massive penalty for visual quality.

Moving to 2560x1440, the same pattern emerges but with lower absolute numbers. Low settings produce 64 FPS, which is still above 60 but only by a narrow margin. Medium settings average 40 FPS with a min of 34 and max of 46 FPS, again showing a 12 FPS variance. High settings average 37 FPS, and Ultra settings average 31 FPS. The difference between Low and Ultra at 1440p is 33 FPS, slightly smaller than at 1080p but still substantial.

At 3840x2160, the 4K resolution, the combo struggles the most. Low settings produce 54 FPS, which is playable but not smooth by modern standards. Medium settings drop to 34 FPS with a min of 29 and max of 39 FPS, and this min of 29 FPS is the lowest recorded value in the entire dataset. High settings average 32 FPS, and Ultra settings average 26 FPS. The difference between Low and Ultra at 4K is 28 FPS, the smallest absolute gap across resolutions, suggesting that the GPU is hitting a hard performance floor at high pixel counts.

The Medium settings rows are the only ones with min and max FPS data, and they reveal an important trend. At 1080p, the spread is 38-52 FPS (14 FPS range), at 1440p it is 34-46 FPS (12 FPS range), and at 4K it is 29-39 FPS (10 FPS range). The narrowing range at higher resolutions could mean that the GPU is consistently saturated at 4K, reducing the opportunity for frame rate spikes, whereas at 1080p there is more headroom that leads to variable performance.

How This Combo Ranks

The combo rank of 2638 out of 2980 places this system in the 88.5th percentile of the worst-performing combos, meaning only 342 combos rank lower. This is a poor result, but it is entirely predictable given the component specifications. The GPU’s percentile of 9 against all GPUs is the dominant factor, as the CPU’s percentile of 74 shows it is a competent mid-range part. The discrepancy between these two percentiles — 65 points apart — creates a severe imbalance that limits the system’s overall capability.

Looking at the nearest CPU rivals, the Ryzen 5 5600GT scores an average benchmark of 20733, which is within 0.5% of the Intel Core i5-12490F (20802, -0.3% delta), the Intel Xeon 6325P (20821, -0.4% delta), the Intel Core Ultra 5 125U (20826, -0.4% delta), and the AMD EPYC 7J13 (20845, -0.5% delta). This tight cluster shows that the CPU is well-matched to other mid-range processors, and its performance is not the reason for the low combo rank.

For the GPU, the nearest rivals are all ancient NVIDIA parts. The Arc B390’s score of 1482 is 1.3% higher than the GeForce GT 520MX, 1.5% higher than the GeForce 800M, 2.5% higher than the GeForce GT 625 OEM, and 2.7% higher than the GeForce GT 710. These are GPUs that were low-end even when they were new, and their presence in the rival list confirms that the Arc B390 is not competitive with any modern discrete graphics solution. The combo rank reflects this reality, as the system is held back by a GPU that is functionally equivalent to a 2012-era entry-level part.

Settings Recommendations

The measured data provides a clear hierarchy for playable settings. For the highest frame rate, Low settings at 1080p with 72 FPS is the unambiguous choice. This is the only configuration that achieves a 60+ FPS average, which is generally considered the baseline for smooth gameplay. The jump from Low to Medium at 1080p costs 27 FPS (from 72 to 45), which is a 37.5% reduction for what is likely a modest visual improvement. Given the GPU’s limitations, prioritizing frame rate over fidelity is the rational approach.

If the user prefers 1440p, Low settings at 64 FPS is still viable, but Medium settings at 40 FPS will feel noticeably less fluid. The 4K resolution is only playable at Low settings with 54 FPS, and even then, the frame rate is below 60. Medium at 4K produces 34 FPS, which is borderline unplayable for an action game, and Ultra at 4K at 26 FPS is effectively a slideshow. The data suggests that 1080p Low is the sweet spot, with 1440p Low as a secondary option for users who prioritize resolution over frame rate.

Ultra settings are never recommended. The best Ultra result is 35 FPS at 1080p, which is 37 FPS lower than Low at the same resolution. For a game like Overpower, which is an action title, frame rate consistency matters more than marginal visual quality. The Medium settings rows show min FPS values of 38 at 1080p, 34 at 1440p, and 29 at 4K, meaning that even Medium can drop to sub-30 territory at high resolutions. Low settings do not have min/max data, but the higher average suggests more headroom and likely fewer dips.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on Zen 3 architecture with a Cezanne codename, built on a 7 nm TSMC process. It has a base clock of 3.60 GHz and a boost clock of 4.60 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. This configuration is well-suited for gaming, as the single-thread performance is strong — evidenced by a Cinebench R23 single-core score of 2438 and a 3DMark single thread score of 913.

The CPU’s benchmark results show solid multi-threaded capability: Cinebench R23 multicore scores 17272, Geekbench multicore scores 7986, and Passmark multithread scores 20325. The 3DMark tests reveal scaling from 1794 (2 threads) to 5554 (max threads), indicating that the processor can effectively utilize its 12 threads. This is important for Overpower, which likely benefits from multi-threaded rendering and physics calculations. The CPU’s percentile of 74 against all CPUs confirms that it is a mid-to-upper-tier processor, not a bottleneck in most scenarios.

However, the CPU’s memory support is DDR4 with dual-channel configuration and 51.2 GB/s bandwidth. This is where the interaction with the GPU becomes problematic. Since the Arc B390 uses system-shared memory, the CPU and GPU are competing for the same bandwidth. The CPU’s memory bandwidth of 51.2 GB/s is adequate for the processor alone, but when the GPU also needs to read and write textures and frame buffers, the shared bus becomes saturated. This contention likely contributes to the lower-than-expected frame rates, particularly at higher resolutions where the GPU needs more memory throughput.

The CPU also has an integrated Radeon Vega 7 GPU, which is separate from the Arc B390. However, the system is using the Intel Arc B390 as the primary display adapter, so the Vega 7 is likely disabled or unused in this configuration. The CPU’s PCIe support is Gen 3 with 16 lanes, which is older but still sufficient for most gaming workloads. The launch MSRP of $140 for the CPU makes it an affordable mid-range option, but the overall system performance is dragged down by the GPU choice.

To sum up, the Ryzen 5 5600GT provides more than enough computational power for Overpower, but it is paired with a GPU that ranks in the 9th percentile. The CPU’s strong single-thread and multi-thread scores are wasted in this configuration, as the GPU cannot translate that compute capability into higher frame rates. The data shows a system where the CPU is capable of 70+ FPS (as evidenced by the 1080p Low result), but the GPU’s limitations cap performance at lower settings and resolutions. For users considering this combo, the CPU is a solid foundation, but the GPU must be upgraded to unlock the system’s true potential.
