How This Combo Ranks

The combo rank of 2417 out of 2740 tested combinations places this system firmly in the lower quartile of performance for Fortnite. This rank is not surprising given the individual component percentiles: the CPU sits at the 71st percentile of all CPUs, but the GPU is at the 9th percentile of all GPUs. The data indicates that the graphics solution is the primary bottleneck, as the integrated Arc B390 with its system-shared memory is far below the performance level of most discrete graphics cards.

To contextualize the rank, consider that the CPU's average benchmark score of 17507 is competitive with its nearest rivals, all of which are within 0.8% of its score. The Ryzen 5 4600G holds its own against these chips in synthetic tests, showing that the processor is not the limiting factor. The GPU, however, with a 3DMark Steel Nomad score of 1482, is only marginally faster than the NVIDIA GeForce GT 520MX, which scores 1463. This places the entire graphics subsystem in a performance class that is roughly a decade old, explaining why the combo ranks so low.

The measured FPS data confirms this analysis. At 1920x1080 with Low settings, the combo achieves 115 FPS, which is respectable for competitive play. However, increasing to Medium settings drops the average to 81 FPS, and High settings further reduce it to 63 FPS. At 2560x1440, the numbers fall to 73 FPS on Low, 51 FPS on Medium, and 40 FPS on High. The 4K results are nominal at best, with 39 FPS on Low being the only setting that exceeds 30 FPS. These results are consistent with a GPU that has 1536 shading units and a FP32 performance of 7.680 TFLOPS, but is constrained by sharing system memory for its frame buffer.

The rank also reflects the fact that most users building a system for Fortnite would opt for a discrete GPU rather than relying on an integrated processor. The Arc B390 is an IGP with a 80 W TDP, designed for portable devices, and its performance is system-dependent regarding memory bandwidth. This makes the combo's rank of 2417 a predictable outcome for a configuration that prioritizes CPU value over GPU capability.

GPU Role

The Intel Arc B390 is the decisive component in this combo's performance, and its specifications explain the measured frame rates. This GPU is built on the Xe3-LPG architecture with a 3 nm process node, featuring 1536 shading units, 48 texture mapping units, and 24 raster output pipelines. It also includes 12 ray tracing cores, though Fortnite's use of these cores is not the primary driver of the low FPS numbers. The GPU's clock speeds are notable: a base clock of 300 MHz and a boost clock of 2500 MHz, which is a wide range that allows for significant performance scaling under load.

The most critical specification for this GPU is its memory configuration, which is "System Shared" for size, type, and bus width. This means the GPU has no dedicated video memory and instead borrows from the system's DDR4 memory. The bandwidth is listed as "System Dependent," which means the actual performance will vary based on the CPU's memory support. In this case, the Ryzen 5 4600G supports dual-channel DDR4 with a memory bandwidth of 51.2 GB/s. This shared memory architecture is a significant bottleneck because the GPU must compete with the CPU for memory access, limiting the effective bandwidth available for rendering.

The measured 3DMark Steel Nomad DX12 score of 1482 puts the Arc B390 at the 9th percentile of all GPUs. Its nearest rivals are all older NVIDIA parts: the GeForce GT 520MX (1463), GeForce 800M (1460), GeForce GT 625 OEM (1446), and GeForce GT 710 (1443). The Arc B390 leads these by 1.3% to 2.7%, but these are all entry-level or ancient parts. This score is consistent with a GPU that has a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. The FP32 performance of 7.680 TFLOPS is adequate for modern titles at low resolutions, but the memory sharing cripples its ability to maintain consistent frame rates as resolution and settings increase.

In Fortnite specifically, the GPU's role is evident in the FPS scaling. At 1920x1080, going from Low to Medium settings reduces average FPS from 115 to 81, a 30% drop. Going from Medium to High reduces it further to 63 FPS, another 22% drop. This scaling is typical of a GPU that is memory-bandwidth limited, as higher settings require more texture data and geometry to be stored in the shared memory pool. The 4K results are even more telling: at 3840x2160, Low settings yield 39 FPS, but Ultra drops to 14 FPS. The GPU simply cannot handle the memory pressure of 4K rendering, resulting in frame rates that are unplayable for any competitive or even casual session.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user's resolution and performance goals. The data shows a clear pattern: Low settings are the only way to achieve frame rates that are suitable for action in Fortnite, while Medium settings are acceptable only at 1080p.

At 1920x1080, Low settings produce an average of 115 FPS, which is the best result across all resolutions and settings. This is the recommended configuration for players who prioritize smoothness and responsiveness, as it keeps the frame rate above the 60 FPS threshold with headroom for dips. Medium settings at 1080p produce 81 FPS average, with a min FPS of 69 and max of 93, which is also playable and offers better visual quality. High settings at 1080p drop to 63 FPS, which is still technically playable but leaves less margin for demanding scenes. Ultra settings at 1080p produce only 41 FPS, which is below the ideal range for a fast-paced game like Fortnite.

For 2560x1440 users, the choices are more constrained. Low settings produce 73 FPS average, which is acceptable for casual play, but Medium settings drop to 51 FPS and High to 40 FPS. Ultra at 1440p yields only 26 FPS, which is not recommended for any gameplay. The 4K resolution is not viable for this combo, as even Low settings only produce 39 FPS, and Medium drops to 27 FPS with a min of 23 FPS.

The best experience per the measured rows is therefore at 1920x1080 with Low settings, which offers the highest average FPS of 115 and is the only setting that reaches triple-digit performance. For users who want a balance between visuals and performance, 1080p Medium at 81 FPS is the next best choice, as it provides a 69 FPS minimum that keeps the action fluid. The data suggests that users should avoid High and Ultra settings at any resolution, as the frame rates fall below 63 FPS even at 1080p, which is marginal for a competitive shooter.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of this combo's performance across three resolutions and four settings levels. At 3840x2160, the results are as follows: Low settings yield an average of 39 FPS, Medium settings yield 27 FPS with a minimum of 23 and maximum of 31, High settings yield 21 FPS, and Ultra settings yield 14 FPS. These numbers indicate that 4K is not a practical resolution for this combo, as even the lowest settings fail to maintain a consistent 30 FPS.

At 2560x1440, the performance improves but remains limited. Low settings produce 73 FPS average, which is the only setting that exceeds 60 FPS at this resolution. Medium settings yield 51 FPS with a minimum of 44 and maximum of 59, which is borderline playable but may experience stutters in busy areas. High settings drop to 40 FPS, and Ultra settings yield 26 FPS, both of which are below the threshold for smooth gameplay.

At 1920x1080, the combo shows its best performance. Low settings achieve 115 FPS average, which is the highest recorded result. Medium settings yield 81 FPS with a minimum of 69 and maximum of 93, providing a solid experience with some visual enhancements. High settings produce 63 FPS, which is playable but on the edge. Ultra settings yield 41 FPS, which is not recommended for serious play.

The scaling between resolutions and settings reveals the GPU's limitations. At Low settings, the average FPS drops from 115 at 1080p to 73 at 1440p (a 37% reduction) and then to 39 at 4K (a 66% reduction from 1080p). This severe scaling is indicative of a GPU that is constrained by its shared memory bandwidth. The difference between Medium and High settings at each resolution is also notable: at 1080p, the drop from 81 to 63 FPS is a 22% reduction, while at 1440p, the drop from 51 to 40 FPS is a 22% reduction as well. This consistent pattern suggests that the GPU's compute capabilities are sufficient, but the memory subsystem cannot keep up with increasing texture loads.

The minimum FPS values, where available, provide additional insight. At 1080p Medium, the minimum is 69 FPS, which is 85% of the average, indicating reasonably stable performance. At 1440p Medium, the minimum is 44 FPS, which is 86% of the average, showing similar stability. At 4K Medium, the minimum is 23 FPS, which is 85% of the average. This consistency across resolutions suggests that frame pacing is not the issue; rather, the overall performance level is simply too low for higher resolutions.

CPU Role

The AMD Ryzen 5 4600G plays a supporting role in this combo, and its specifications indicate that it is more than capable of handling Fortnite's CPU demands. This processor is built on the Zen 2 architecture (codename Renoir) using a 7 nm process node from TSMC, with 9,800 million transistors on a 156 mm² die. It has 6 cores and 12 threads, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. The TDP is 65 W, making it a power-efficient choice for a desktop system.

The CPU's cache hierarchy includes 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 8 MB of shared L3 cache. This is a modest amount of L3 cache by modern standards, but Fortnite is not a cache-sensitive title. The memory support is DDR4 with dual-channel configuration, providing a memory bandwidth of 51.2 GB/s. This bandwidth is shared with the GPU, which is a critical factor in the combo's overall performance. The CPU has 20 PCIe Gen 3 lanes, which is sufficient for a single GPU and storage devices.

Benchmark results show that the Ryzen 5 4600G performs well in synthetic tests. Its Cinebench R23 multicore score is 13593, and its single-core score is 1919. In Geekbench, it scores 6637 multicore and 1460 single-core. The PassMark multithread score is 15992, and the single-thread score is 2653. These numbers place the CPU at the 71st percentile of all CPUs, which is respectable for a processor in its price range. The nearest rivals are all within a narrow band: the Ryzen 3 PRO 5355GE scores 17482 (0.1% behind), the Ryzen 3 8300GE scores 17614 (0.6% ahead), the Core 7 150U scores 17395 (0.6% behind), and the Core i3-14100T scores 17648 (0.8% ahead).

In the context of Fortnite, the CPU's role is to handle game logic, physics, and the rendering pipeline's draw calls. The 6 cores and 12 threads are more than sufficient for this task, as Fortnite is not heavily multi-threaded. The single-core performance, as measured by Cinebench R23 single-core score of 1919, is adequate for the game's main thread. The CPU's benchmark scores suggest that it is not a significant bottleneck in this combo, as it performs within 1% of its direct competitors.

However, the CPU's memory bandwidth of 51.2 GB/s becomes a limiting factor when paired with the Arc B390's system-shared memory. The GPU needs to access the same DDR4 memory for its frame buffer, and the CPU's memory controller must handle both processor and graphics traffic. This shared access reduces the effective bandwidth available to each component, which is a primary reason why the GPU's performance is lower than its compute specifications would suggest. The CPU's 8 MB L3 cache helps mitigate some memory latency, but it cannot compensate for the bandwidth deficit when the GPU is under load.

The data shows that the CPU is not the reason this combo ranks 2417 out of 2740. At 1080p Low, the combo achieves 115 FPS, which is a result that is CPU-limited in many systems. The fact that the FPS drops significantly when increasing resolution or settings points to the GPU as the bottleneck, not the CPU. The Ryzen 5 4600G is a capable processor for Fortnite, but the integrated graphics solution it is paired with here is the limiting factor.
