Fortnite

The AMD Ryzen 5 4600G and Intel Arc B570 pairing produces a system that is firmly mid-pack for Fortnite, ranking 2972 out of 3700 tested combinations. The data shows a CPU with solid multi-threaded capability but modest single-thread performance, paired with a GPU that has ample VRAM and raw throughput for 1080p gaming. The measured frames per second across three resolutions reveal a system that is clearly GPU-limited at higher settings, but which becomes increasingly CPU-bound as resolution drops and settings are lowered. This analysis breaks down exactly what each component contributes, how the system scales, and which settings deliver the best experience.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 5 4600G is a 6-core, 12-thread processor built on the Zen 2 architecture, running at a base clock of 3.70 GHz and a boost clock of 4.20 GHz. It is a 65 W part on the AM4 socket, with 8 MB of shared L3 cache. Its benchmark profile shows a clear split: multi-threaded scores are respectable, but single-thread performance lags behind what modern gaming CPUs achieve. For instance, the Cinebench R23 multi-core score of 13593 places it well above entry-level parts, while the single-core score of 1919 is comparatively modest. The Geekbench single-core score of 1460 reinforces this pattern.

Fortnite is a game that relies heavily on single-thread performance for its main game logic and physics, but it also scales reasonably well across multiple cores for rendering tasks. The 4600G’s 12 threads mean it will not bottleneck the Arc B570 in most scenarios, but the weak single-thread scores suggest that at very high frame rates—particularly at 1080p Low settings—the CPU could become the limiting factor. The measured data supports this: at 1920x1080 Low, the system hits 176 FPS on average, which is high but not exceptionally so, suggesting the CPU is starting to constrain the GPU’s potential.

Compared to its nearest rivals, the 4600G sits in a tight cluster. The AMD Ryzen 3 PRO 5355GE scores 17482 on average, just 0.1% lower, while the Intel Core 7 150U scores 17395, 0.6% lower. The AMD Ryzen 3 8300GE and Intel Core i3-14100T are marginally ahead, with scores of 17614 and 17648, respectively, representing deltas of -0.6% and -0.8% from the 4600G’s perspective. This means the CPU is effectively performance-neutral against its direct competitors—none of these parts will dramatically change Fortnite’s outcome. The 4600G’s 71st percentile ranking among all CPUs confirms it is a workable, if unspectacular, gaming processor.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B570 is a Battlemage-generation GPU with 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. It runs at a fixed 2500 MHz clock for both base and boost, and its 2304 shading units process data at 11.52 TFLOPS of FP32 throughput. The 10 GB VRAM is a significant advantage in modern games, and while Fortnite is not particularly VRAM-hungry at 1080p, it becomes more demanding at 4K Ultra settings. The GPU’s 18 ray tracing cores and support for DirectX 12 Ultimate mean it is fully capable of handling Fortnite’s more advanced visual features.

The Arc B570’s benchmark scores show a GPU that is competitive with mid-range offerings from other vendors. Its Passmark G3D score of 14195 places it in the 65th percentile of all GPUs. The nearest rival, the NVIDIA GeForce RTX 3070 Mobile, scores 20534 on average, a 0.1% difference, while the Intel Arc A750 scores 20582, -0.1% from the B570. The NVIDIA Quadro M4000M and AMD Radeon R9 M390X are also within 0.5% of the B570’s average score of 20556. This indicates that the B570 is a known quantity in terms of raw performance, though the measured Fortnite FPS will tell the real story.

In Fortnite, the GPU’s role becomes evident in the resolution scaling. At 1920x1080 High, the system achieves 96 FPS, which is a playable frame rate. However, the gap between Low and Ultra settings at 1080p is stark: 176 FPS versus 64 FPS. This 112 FPS spread shows that the GPU is doing heavy lifting at Ultra, but the CPU can keep up at Low. The 10 GB VRAM is not the limiting factor here; rather, it is the GPU’s raw compute power that determines the high-setting performance. The B570’s 380.0 GB/s bandwidth is sufficient for Fortnite’s textures, even at 4K, where the Ultra preset only manages 21 FPS, indicating compute limits rather than memory constraints.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across 1080p, 1440p, and 4K reveals a classic scaling pattern that identifies the bottleneck. At 1920x1080 Low, the system averages 176 FPS. Moving to 2560x1440 Low drops that to 112 FPS, a 36% reduction. At 3840x2160 Low, the average falls to 59 FPS, another 47% drop. This steep decline with resolution is the signature of a GPU-limited system—the CPU is capable of feeding the GPU at 1080p, but the GPU cannot maintain that throughput as pixel count increases.

However, the story changes slightly at Ultra settings. At 1080p Ultra, the system averages 64 FPS. At 1440p Ultra, it drops to 40 FPS, a 37.5% reduction. At 4K Ultra, it falls to 21 FPS, a 47.5% drop from 1440p. The percentage drops are similar to Low settings, but the absolute numbers are much lower, confirming that the GPU is the dominant constraint across all settings. The CPU is not the limiting factor at Ultra, as the frame rates are too low to stress the 4600G’s single-thread performance.

The Medium settings provide the clearest picture. At 1080p Medium, the system hits 124 FPS with a minimum of 106 FPS and a maximum of 143 FPS. At 1440p Medium, it averages 79 FPS with a minimum of 67 and a maximum of 91. At 4K Medium, it drops to 42 FPS with a minimum of 35 and a maximum of 48. The consistent minimum-to-maximum spread of roughly 27-30% at each resolution indicates stable frame pacing, with the GPU being the primary limiting component. If the CPU were the bottleneck, the minimum FPS would likely be lower relative to the average, especially at 1080p. The data shows the 4600G is sufficient for this GPU at all tested resolutions, but the Arc B570 is the component that decides the final frame rate.

FAQ

Q: Can this system run Fortnite at 1080p with high settings?

A: Yes. The measured average at 1920x1080 High is 96 FPS, which is well above the 60 FPS threshold for smooth gameplay. The system has headroom for dips, though the minimum FPS is not listed for this preset.

Q: What is the highest preset that maintains 60 FPS at 1440p?

A: The data shows that High settings at 2560x1440 average 61 FPS, which just meets the 60 FPS target. Medium settings at the same resolution average 79 FPS, providing more comfortable headroom. Ultra at 1440p only averages 40 FPS, so it is not viable for 60 FPS play.

Q: Is 4K gaming possible with this combination?

A: Only at Low settings, where the system averages 59 FPS at 3840x2160. Medium settings drop to 42 FPS, and High falls to 32 FPS. Ultra at 4K is not playable, averaging just 21 FPS. The 10 GB VRAM is sufficient, but the GPU’s compute power is insufficient for higher presets at 4K.

Q: How does the CPU compare to its direct rivals for Fortnite?

A: The Ryzen 5 4600G is effectively performance-neutral against its nearest competitors. The AMD Ryzen 3 PRO 5355GE is 0.1% slower, the Intel Core 7 150U is 0.6% slower, and the AMD Ryzen 3 8300GE and Intel Core i3-14100T are 0.6% and 0.8% faster, respectively. None of these differences will be noticeable in Fortnite.

Q: What is the best resolution for a high-refresh-rate monitor?

A: At 1920x1080 Low, the system averages 176 FPS, which is suitable for a 144 Hz or 165 Hz display. Medium settings at 1080p average 124 FPS, still above 120 FPS. For a 240 Hz monitor, only Low settings at 1080p would come close, as High settings drop to 96 FPS.

Q: Is the Arc B570’s 10 GB VRAM enough for Fortnite’s highest textures?

A: The data shows that VRAM is not the limiting factor. At 4K Ultra, the system averages 21 FPS, but this is due to compute limits, not memory capacity. The GPU’s 380.0 GB/s bandwidth and 2304 shading units are the constraints. The 10 GB VRAM is ample for Fortnite’s textures at all tested settings.

Settings Recommendations

For the best balance of visual quality and frame rate, Medium settings at 1920x1080 are the clear winner. The system averages 124 FPS with a minimum of 106 FPS and a maximum of 143 FPS, providing a smooth experience that stays well above 100 FPS even in demanding scenes. This preset offers a significant visual upgrade over Low while maintaining a frame rate that is suitable for competitive play.

If you prioritize frame rate over visuals, Low settings at 1080p deliver 176 FPS on average, which is ideal for esports-oriented play on high-refresh-rate monitors. The jump from Low to Medium costs 52 FPS, which is a substantial trade-off. However, the minimum FPS data for Medium (106 FPS) shows that even in worst-case scenarios, the system stays above 100 FPS, making Medium the safer choice for consistent performance.

At 1440p, Medium settings are the recommended preset, averaging 79 FPS with a minimum of 67 FPS. This is a playable frame rate for most users, and the visual fidelity at 1440p Medium is superior to 1080p Ultra. High settings at 1440p average 61 FPS, which is exactly at the 60 FPS threshold, leaving little room for dips. The data suggests that Medium at 1440p is the sweet spot for this resolution.

For 4K, the only viable option is Low settings, which average 59 FPS. Medium at 4K drops to 42 FPS, which is below the 60 FPS target and will feel less responsive. Unless you have a 60 Hz 4K monitor and are willing to accept occasional dips, 4K is not recommended with this hardware. Stick to 1080p or 1440p for the best experience.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system performs as follows:

• Low: 176 FPS average
• Medium: 124 FPS average, with a minimum of 106 FPS and a maximum of 143 FPS
• High: 96 FPS average
• Ultra: 64 FPS average

The 1080p results show a clear progression: each step up in settings costs roughly 30-50 FPS. The jump from Low to Medium is the largest single drop at 52 FPS, while the drop from High to Ultra is 32 FPS. This suggests that Medium is the most efficient setting in terms of performance-per-visual-quality at this resolution.

At 2560x1440, the measured results are:

• Low: 112 FPS average
• Medium: 79 FPS average, with a minimum of 67 FPS and a maximum of 91 FPS
• High: 61 FPS average
• Ultra: 40 FPS average

The 1440p data shows a similar pattern to 1080p, but with lower absolute numbers. The drop from Low to Medium is 33 FPS, from Medium to High is 18 FPS, and from High to Ultra is 21 FPS. The Medium preset’s minimum of 67 FPS is notably higher than the High preset’s average of 61 FPS, making Medium the recommended choice for consistent 60+ FPS gameplay.

At 3840x2160, the results are:

• Low: 59 FPS average
• Medium: 42 FPS average, with a minimum of 35 FPS and a maximum of 48 FPS
• High: 32 FPS average
• Ultra: 21 FPS average

The 4K data shows that the Arc B570 is not powerful enough for high-fidelity gaming at this resolution. Even Low settings barely break 60 FPS, and the Medium preset’s minimum of 35 FPS indicates significant frame drops. The gap between Low and Medium is 17 FPS, while High and Ultra are both below 32 FPS, making them unsuitable for playable frame rates. The system is clearly optimized for 1080p and 1440p gaming, with 4K reserved for Low settings only.
