Fortnite

The AMD Ryzen 5 4600G paired with the Intel Arc B370 is a combination that clearly prioritizes low power consumption over raw frame rate. Benchmark data for Fortnite shows a system that is functional at lower resolutions and settings but struggles significantly as graphical demands increase. The Arc B370 operates as an integrated graphics processor (IGP) with system-shared memory, which heavily influences its performance profile across the board. This analysis breaks down the measured FPS data to explain where this combo excels, where it falls short, and what settings offer the most playable experience.

Resolution Scaling

The measured FPS data reveals a steep performance cliff as resolution increases. At 1080p with Low settings, the combo achieves an average of 104 FPS, which drops to 66 FPS at 1440p and further to 35 FPS at 4K. This translates to a 66% performance loss when moving from 1080p to 1440p, and a 66% loss again from 1440p to 4K. The scaling is not linear, indicating that the system is being pushed into a bottleneck that grows disproportionately with pixel count.

The jump from Low to Medium settings at 1080p shows a significant cost: average FPS falls from 104 to 73, a 30% reduction. At 1440p, that same settings change drops performance from 66 to 46 FPS, also roughly a 30% penalty. This consistent proportional drop suggests that while the GPU is the primary limiter, the CPU's six cores and twelve threads are still able to keep up with the workload at these settings, allowing the graphics pipeline to be the sole bottleneck.

However, at 4K, the scaling becomes brutal. High settings yield only 19 FPS, and Ultra drops to 13 FPS. The gap between Low (35 FPS) and Medium (25 FPS) at 4K is 29%, but the difference between Medium and High is a 24% drop. This pattern indicates that the system-shared memory architecture of the Arc B370 becomes a severe constraint at high resolutions, as the memory bandwidth is "System Dependent" and likely insufficient for the data throughput required at 4K.

The min and max FPS data points available for Medium settings provide additional insight. At 1080p Medium, the frame times range from 62 to 84 FPS, showing a 22 FPS variance. At 1440p Medium, the range is 39 to 53 FPS, a 14 FPS variance. At 4K Medium, the range tightens to 21 to 28 FPS, a 7 FPS variance. The shrinking variance at higher resolutions suggests that the system is becoming more consistently bottlenecked, with less headroom for burst performance.

GPU Role

The Intel Arc B370 is the central figure in this combo's performance story. With a boost clock of 2400 MHz and a base clock of 300 MHz, the GPU has a wide operating range, but its integrated nature defines its capabilities. The 3DMark Steel Nomad DX12 benchmark score of 1184 places this GPU in the 5th percentile of all tested GPUs, which is exceptionally low. Its nearest rivals in terms of average score are the ATI Mobility Radeon HD 5570 (deltaPct -0.2%) and the ATI Radeon HD 5770 (deltaPct -0.5%), both of which are legacy parts from a different era.

The GPU features 1280 shading units, 40 texture mapping units, and 20 raster output pipelines. These specifications translate to a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The FP32 performance is rated at 6.144 TFLOPS, which sounds respectable on paper but is hamstrung by the memory architecture. The memory size, type, and bus width are all listed as "System Shared," and the bandwidth is "System Dependent." This is the critical weakness.

In Fortnite, the data shows that this GPU cannot handle 4K resolution at any settings above Low, where it manages only 35 FPS. The VRAM situation is non-existent in the traditional sense, as the GPU relies entirely on system memory, which is also used by the CPU. This contention for memory bandwidth explains why the performance degrades so sharply at higher resolutions where memory pressure increases. The GPU's 25 W TDP and "IGP" slot width confirm that this is not a discrete solution, and the lack of dedicated VRAM is the primary reason for its poor scaling.

The GPU's support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 means it is feature-complete for modern APIs, but the hardware cannot deliver the performance those APIs demand at high resolutions. The 10 ray tracing cores are present, but with the low fill rates and shared memory, enabling any ray-traced effects would likely be catastrophic for frame rates, though no specific data points for that scenario are available.

CPU Role

The AMD Ryzen 5 4600G provides the processing foundation for this combo. With 6 cores and 12 threads based on the Zen 2 architecture, it is a capable mid-range processor from the 4000 series. The base clock of 3.70 GHz can boost up to 4.20 GHz, and the 65 W TDP makes it an efficient part. The CPU's L3 cache is 8 MB (shared), which is modest but sufficient for a game like Fortnite that is not particularly cache-hungry.

In CPU-centric benchmarks, the 4600G posts a Cinebench R23 multicore score of 13593 and a single-core score of 1919. The Geekbench scores are 6637 multicore and 1460 single-core. These results place the CPU in the 71st percentile of all CPUs, indicating it is a solid mid-pack performer. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE (deltaPct 0.1%) and the Intel Core i3-14100T (deltaPct -0.8%), showing it trades blows with modern low-power parts.

The CPU's performance in the measured Fortnite data is somewhat masked by the GPU bottleneck, but we can infer its role from the scaling patterns. At 1080p Low, the system hits 104 FPS, which suggests the CPU is capable of feeding the GPU enough data to reach a playable frame rate. The 3DMark 8-thread score of 4138 and the max-thread score of 4889 indicate that the CPU has sufficient multi-threaded headroom for a game that typically uses fewer than 8 threads effectively.

The CPU's memory support is DDR4 with a dual-channel bus, providing 51.2 GB/s of bandwidth. This is the same memory pool that the GPU must share for its "System Shared" VRAM. This shared bandwidth is the key point of contention. When the CPU is processing game logic and the GPU is simultaneously pulling texture data from the same memory, the dual-channel DDR4 bandwidth becomes a limiting factor. This is why the combo struggles so much at 4K, where the GPU needs significantly more data per frame.

The CPU's single-thread performance, as evidenced by the 3DMark single-thread score of 726 and Cinebench R20 single-core score of 805, is adequate for Fortnite's engine, which relies heavily on a few primary threads. However, the boost clock of 4.20 GHz is not exceptional, and the data suggests that while the CPU is not the primary bottleneck at lower settings, it may contribute to the overall frame pacing issues at higher resolutions where the GPU's memory demands slow everything down.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend entirely on the target resolution. At 1080p, the Low preset delivers 104 FPS, which is smooth for competitive play. The Medium preset at 73 FPS is still playable and offers better visual quality, with min and max FPS of 62 and 84 respectively, indicating reasonably stable frame times. The High preset at 57 FPS is borderline, dipping below the 60 FPS threshold that many players prefer for a fast-paced Battle Royale.

At 1440p, the situation becomes more constrained. Low settings yield 66 FPS, which is acceptable, but Medium drops to 46 FPS, which is below the ideal range for competitive Fortnite. High at 36 FPS and Ultra at 24 FPS are not recommended for any serious play. For 4K, the data is clear: only the Low preset at 35 FPS is even remotely playable, and even that is marginal. Medium at 25 FPS and High at 19 FPS are slideshows, while Ultra at 13 FPS is unplayable.

The best experience per the measured rows is 1080p with Low settings, offering the highest frame rate and most responsive gameplay. If visual fidelity is a priority, 1080p Medium provides a 73 FPS average with a 62 FPS minimum, which maintains playability while improving the look of the game. For users with a 1440p monitor, the Low preset is the only viable option, as the 66 FPS average is workable but leaves no headroom for demanding scenes.

It is importantly the Ultra preset is a trap for this hardware. At 1080p Ultra, the average FPS is 37, which is worse than 1440p High (36 FPS) and only slightly better than 4K Medium (25 FPS). The performance cost of Ultra settings is disproportionate to the visual gain on this GPU, making it a poor choice regardless of resolution. The data suggests that users should avoid Ultra entirely and instead use the CPU's unlocked multiplier to overclock if they need more performance, though no specific overclocking results are provided.

How This Combo Ranks

The combo's ranking in Fortnite is 2517 out of 2740 tested combinations, placing it in the bottom 8% of all systems. This is a very low ranking, consistent with the GPU's 5th percentile performance. The combo's percentile position is heavily dragged down by the Arc B370's integrated nature, which cannot compete with even entry-level discrete GPUs.

The CPU's 71st percentile ranking does little to offset the GPU's poor standing. In the context of Fortnite, which is a GPU-bound title at most settings, the CPU's relative strength is irrelevant when the GPU cannot translate that processing power into frames. The nearest rival GPUs for the Arc B370 are the ATI Mobility Radeon HD 5570 and the ATI Radeon HD 5770, both of which are over a decade old, underscoring how far behind the performance curve this integrated solution sits.

The rank of 2517 out of 2740 means that 223 combos perform worse than this system. This places it in the company of other low-end integrated solutions, but it is still a functional system for Fortnite at low settings. The data shows that while the combo is not competitive for high-refresh-rate play, it can handle the game at its most basic settings, which is arguably its intended use case given the 25 W TDP of the GPU.
