Fortnite

The AMD Ryzen 5 2600 paired with the Intel Arc B390 produces a highly constrained gaming experience in Fortnite, with performance heavily dependent on resolution and quality settings. Benchmark data shows a clear pattern: the combo delivers playable frame rates only at 1080p with reduced settings, while higher resolutions push it into slideshow territory. This analysis breaks down the measured results, contextualizes them against the component specifications, and provides practical guidance based strictly on the observed data.

Settings Recommendations

The measured frame rates across all resolutions and presets indicate that this system is fundamentally limited in Fortnite. At 1920x1080, the Low preset delivers an average of 115 FPS, which is the only configuration that approaches what most players would consider a smooth competitive experience. This represents a 42% improvement over the Medium preset’s 81 FPS average, and a 74 FPS gap over the High preset’s 63 FPS. The data strongly suggests that Low settings at 1080p is the only viable option for responsive gameplay, as the Medium preset’s minimum frame rate of 69 FPS dips below the 70 FPS threshold that many players find acceptable for fast-paced action.

The Ultra preset at 1080p yields only 41 FPS average, which is below the 60 FPS minimum standard for most modern titles. Given that the Low preset more than doubles the Ultra preset’s frame rate at the same resolution, the performance cost of Ultra settings is prohibitive. The Medium preset offers a compromise with 81 FPS average and a 69 FPS minimum, but the 12 FPS margin between average and minimum suggests occasional stutter during intense combat scenes. For players prioritizing frame rate stability, Low settings at 1080p is the clear recommendation, as it provides the highest average and eliminates the risk of drops below playable thresholds.

At 2560x1440, even the Low preset drops to 73 FPS average, which is borderline acceptable but lacks the headroom of the 1080p Low configuration. The Medium preset at this resolution averages 51 FPS with a 44 FPS minimum, which falls below the playable threshold for most users. The High and Ultra presets at 1440p, averaging 40 FPS and 26 FPS respectively, are not recommended for any gameplay scenario. At 3840x2160, the Low preset’s 39 FPS average is the only setting that approaches minimum playability, but the Medium preset’s 23 FPS minimum and 27 FPS average make 4K gaming impractical for this combo. The data supports 1080p Low as the optimal configuration, with 1080p Medium as a secondary option for users who prioritize visual quality over maximum frame rates.

GPU Role

The Intel Arc B390’s specifications explain much of the observed performance ceiling. With a base clock of 300 MHz and a boost clock of 2500 MHz, the GPU’s clock range is wide, but the sustained performance in Fortnite suggests it operates near its limits under load. The chip, built on Intel’s 3 nm process with the Xe3-LPG architecture, features 1536 shading units, 48 texture mapping units, and 24 render output units. The 12 ray tracing cores have minimal impact on this game’s measured results, as none of the tested presets appear to leverage RT features based on the frame rate progression.

The most critical limitation is the memory configuration: the B390 uses System Shared memory, meaning its VRAM size, bus width, and bandwidth are all system dependent rather than fixed specifications. This architecture forces the GPU to compete with the CPU for memory bandwidth, which likely contributes to the steep performance drop as resolution increases. The GPU’s pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s provide theoretical ceilings, but the shared memory bottleneck appears to be the dominant constraint in Fortnite’s rendering pipeline.

The GPU’s benchmark results reinforce its position as a low-end part. Its 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, with its nearest rivals being the NVIDIA GeForce GT 520MX (1463 score, 1.3% faster), NVIDIA GeForce 800M (1460 score, 1.5% faster), NVIDIA GeForce GT 625 OEM (1446 score, 2.5% faster), and NVIDIA GeForce GT 710 (1443 score, 2.7% faster). This indicates the B390 is essentially competing with integrated graphics and entry-level discrete GPUs from over a decade ago. The 7.680 TFLOPS FP32 throughput and 15.36 TFLOPS FP16 performance (2:1 ratio) are respectable on paper, but the shared memory architecture and system dependence negate these advantages in real-world gaming scenarios.

Resolution Scaling

The measured FPS data reveals a stark resolution scaling pattern that points to the GPU as the primary bottleneck. At Low settings, the frame rate drops from 115 FPS at 1920x1080 to 73 FPS at 2560x1440, a 36.5% reduction, and further to 39 FPS at 3840x2160, a 66.1% reduction from the 1080p baseline. This scaling is consistent with a GPU that becomes increasingly memory-bandwidth constrained as pixel count grows. The pixel throughput requirement quadruples from 1080p to 4K, and the shared memory system cannot sustain the necessary bandwidth.

The Medium preset shows a similar pattern: 81 FPS at 1080p, 51 FPS at 1440p (37% drop), and 27 FPS at 4K (66.7% drop). The High preset follows with 63 FPS at 1080p, 40 FPS at 1440p (36.5% drop), and 21 FPS at 4K (66.7% drop). The consistency of these percentage drops across settings suggests that the scaling penalty is resolution-driven rather than settings-driven, reinforcing the conclusion that the GPU’s memory subsystem is the limiting factor. Even the Ultra preset, which starts at a low 41 FPS at 1080p, drops to 26 FPS at 1440p (36.6% drop) and 14 FPS at 4K (65.9% drop).

The 4K to 1080p ratio shows that the combo loses roughly two-thirds of its frame rate when moving from Full HD to 4K, regardless of quality preset. This indicates that the CPU’s 6 cores and 12 threads are not the limiting factor at higher resolutions; if the CPU were the bottleneck, the frame rate would remain relatively flat as resolution increases. Instead, the steep decline confirms that the Intel Arc B390’s shared memory architecture cannot feed the rendering pipeline fast enough at higher pixel counts. The data suggests that 1080p is the practical ceiling for this combo, with 1440p only viable at Low settings for users willing to accept a 73 FPS average.

FAQ

Q: How does the Ryzen 5 2600’s overall benchmark performance compare to other CPUs?

A: The CPU’s average benchmark score of 21484 places it in the 75th percentile of all CPUs. Its nearest rivals include the Intel Core Ultra 5 228V (21440, 0.2% faster), Intel Core i9-11900H (21367, 0.5% faster), Intel Xeon D-1746TER (21635, 0.7% slower), and AMD EPYC 9454 (21223, 1.2% faster).

CPU Role

The AMD Ryzen 5 2600 provides the computational foundation for this combo, and its specifications suggest it is not the primary constraint in Fortnite. With 6 cores and 12 threads based on the Zen architecture (specifically Zen+ Pinnacle Ridge), the CPU operates at a 3.40 GHz base clock and 3.90 GHz boost clock. This 2000 series processor, built on GlobalFoundries’ 12 nm process with 4,800 million transistors on a 213 mm² die, features a 16 MB shared L3 cache along with 96 KB L1 and 512 KB L2 cache per core. The dual-channel DDR4 memory support with 46.9 GB/s bandwidth provides adequate throughput for the frame rates observed.

The CPU’s benchmark results show a balanced profile that supports mid-range gaming performance. In Cinebench R15, it scores 1248 in multicore and 157.3 in single-core tests. Geekbench results show 5648 multicore and 1154 single-core scores. PassMark tests reveal strengths in data compression (187062), integer math (44518), and floating point math (22942), while weaker scores appear in find prime numbers (37) and physics (673). The single-thread score of 2239 in PassMark is particularly relevant for gaming, as many game engines rely heavily on single-core performance.

The CPU’s average benchmark score of 21484 places it at the 75th percentile of all CPUs, indicating it outperforms three-quarters of tested processors. Its nearest rivals are all within 1.2% in either direction: the Intel Core Ultra 5 228V is 0.2% faster, the Intel Core i9-11900H is 0.5% faster, the Intel Xeon D-1746TER is 0.7% slower, and the AMD EPYC 9454 is 1.2% faster. This tight clustering suggests the Ryzen 5 2600 sits at a performance plateau where small variations in workload determine the ranking.

In the context of Fortnite, the CPU’s 12 threads handle the game’s background tasks and physics calculations without appearing to bottleneck the frame rate. The fact that FPS scales so dramatically with resolution indicates the GPU is the limiting component, as a CPU bottleneck would manifest as consistent frame rates regardless of pixel count. The 65 W TDP and unlocked multiplier offer headroom for overclocking, but the measured data does not indicate that CPU frequency is the governing factor in this game’s performance.

Measured FPS Breakdown

The complete set of measured frame rates provides a detailed picture of this combo’s capabilities. At 1920x1080, the Low preset achieves an average of 115 FPS, which is the highest score recorded across all configurations. The Medium preset at this resolution averages 81 FPS with a 69 FPS minimum and 93 FPS maximum, showing a 12 FPS fluctuation range. High settings at 1080p drop to 63 FPS average, while Ultra falls to 41 FPS average. The progression from Low to Ultra at 1080p shows a 74 FPS total drop, with the largest single-step decrease occurring between Medium and High (18 FPS) and the smallest between High and Ultra (22 FPS).

At 2560x1440, the Low preset averages 73 FPS, which is 42 FPS lower than the same settings at 1080p. Medium at 1440p averages 51 FPS with a 44 FPS minimum and 59 FPS maximum, representing a 15 FPS fluctuation range that is wider in percentage terms than at 1080p. High settings at 1440p yield 40 FPS average, and Ultra drops to 26 FPS average. The 1440p results show the same pattern as 1080p, but every preset is shifted down by roughly 35-40%, confirming the GPU’s resolution scaling limitations.

At 3840x2160, the Low preset averages 39 FPS, which is the only 4K configuration that exceeds 30 FPS. Medium at 4K averages 27 FPS with a 23 FPS minimum and 31 FPS maximum, making it the only 4K setting with recorded minimum and maximum values. High at 4K drops to 21 FPS average, and Ultra falls to 14 FPS average. The 4K results demonstrate a clear hierarchy: Low is the most playable, but even the best 4K option would be challenging for competitive play. The Medium preset’s 23 FPS minimum represents the lowest recorded value in the entire dataset, highlighting the performance floor for this combo.

How This Combo Ranks

The AMD Ryzen 5 2600 and Intel Arc B390 combination ranks 2417 out of 2740 tested combos in Fortnite, placing it in the bottom 12% of all configurations. This ranking reflects the GPU’s severe performance limitations, as the CPU alone performs at the 75th percentile. The gap between the CPU’s relative strength and the combo’s poor overall ranking underscores the extent to which the Arc B390 drags down the system’s gaming capabilities.

The GPU’s 9th percentile ranking among all GPUs is the dominant factor in this combo’s position. With a 3DMark Steel Nomad DX12 score of 1482, the Arc B390 sits in the company of legacy NVIDIA parts like the GT 520MX and GT 710, which are not designed for modern gaming workloads. The combo’s ranking suggests that users would need to dramatically lower expectations for visual quality and resolution to achieve playable frame rates, as the measured data confirms.

The 2417th position out of 2740 combos means that only 323 tested configurations perform worse in Fortnite. This places the combo in the lowest performance tier, suitable only for 1080p gaming at Low settings or less demanding titles. The data indicates that pairing the Ryzen 5 2600 with a more capable GPU would likely yield significantly better results, but with the Arc B390, the system is firmly limited to entry-level gaming scenarios. The combination’s ranking is consistent with its measured FPS results, which show playable performance only at 1080p Low and marginal results at 1080p Medium.
