Fortnite

The AMD Ryzen 7 3700X and Intel Arc B580 pairing produces a mid-pack Fortnite experience, landing in the 1206th position out of 1564 tested combinations. The data indicates a system that is heavily reliant on graphics settings to achieve playable frame rates, with the CPU providing a stable foundation while the GPU becomes the primary bottleneck at higher resolutions and presets.

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

The AMD Ryzen 7 3700X is an 8-core, 16-thread processor based on the Zen 2 architecture, running on the AMD Socket AM4 platform. Its base clock of 3.60 GHz and boost clock of 4.40 GHz are moderate by current standards, but the processor’s strength lies in its multi-threaded capacity. Benchmark data shows a Cinebench R23 multi-core score of 19087 and a single-core score of 2694, placing it in the 85th percentile of all CPUs tested. This indicates that while single-thread performance is adequate for gaming, the processor’s overall capability is competitive with its immediate peers.

In Fortnite, the CPU’s role is to feed the GPU with draw calls and manage game logic. The measured FPS data shows that at 1080p with Low settings, the system achieves 198.5 FPS, which is a strong indicator that the CPU can keep up with high frame rates when the GPU is not overburdened. However, the processor’s average benchmark score of 28631 is nearly identical to its nearest rivals, including the Intel Core i5-12600 (deltaPct -0.1) and the AMD Ryzen 5 5600XT (deltaPct 0.1). This suggests that the 3700X is not a limiting factor in this combo; instead, it provides a balanced baseline that allows the GPU to be the primary performance driver.

The 32 MB of L3 cache and dual-channel DDR4 memory support (with a bandwidth of 51.2 GB/s) are sufficient for Fortnite’s requirements. The processor’s 7 nm process node and 65 W TDP also indicate an efficient design that won’t introduce thermal throttling issues in a typical gaming scenario. The data shows that the CPU is not the bottleneck at 1080p, as the FPS scales dramatically with settings changes, but at 4K Ultra, the frame rate drops to 22.3 FPS, which is far below the CPU’s potential output, confirming that the GPU is the limiting component in this pairing.

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

The Intel Arc B580 is a Battlemage-generation GPU with 12 GB of GDDR6 memory on a 192-bit bus, delivering a memory bandwidth of 456.0 GB/s. Its base and boost clocks are both 2670 MHz, and the memory operates at 2375 MHz (19 Gbps effective). The GPU’s 2560 shading units and 80 ROPs give it a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s. In compute benchmarks, the Arc B580 scores 15748 in Passmark G3D and 3068 in 3DMark Steel Nomad, placing it in the 66th percentile of all GPUs.

The GPU’s performance in Fortnite is directly tied to the settings and resolution. At 1080p Low, the Arc B580 delivers 198.5 FPS, which is an excellent result and shows the GPU’s raw throughput. However, the performance degrades sharply as settings increase: at 1080p High, the average FPS drops to 107.7, and at 1080p Ultra, it falls to 73.2. This pattern is consistent with a GPU that has strong compute power but may be limited by driver overhead or memory bandwidth in certain scenarios. The nearest rival, the NVIDIA GeForce RTX 4060, has a similar average benchmark score (23181 vs 23021, deltaPct -0.7), indicating that the Arc B580 is broadly comparable to that card in synthetic tests.

The 12 GB VRAM is not a limiting factor at any resolution tested, as even at 4K Ultra, the frame rate is constrained by compute power rather than memory capacity. The GPU’s 190 W TDP and dual-slot design suggest it can maintain boost clocks under load, but the data shows that Fortnite at Ultra settings is too demanding for this GPU to provide a smooth experience, with 4K Ultra averaging just 22.3 FPS.

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

The measured FPS data reveals a clear scaling pattern across resolutions. At Low settings, the system goes from 198.5 FPS at 1080p to 125 FPS at 1440p (a 37% drop) and then to 65.3 FPS at 4K (a 48% drop from 1440p). This indicates that at Low settings, the CPU has enough headroom to feed the GPU, but the GPU becomes increasingly stressed as pixel count rises. The drop from 1080p to 1440p is significant, but the further drop to 4K is even steeper, suggesting that the Arc B580’s compute resources are being saturated.

At High settings, the scaling is similar but with a different starting point: 107.7 FPS at 1080p drops to 71.5 FPS at 1440p (a 34% drop) and then to 37.7 FPS at 4K (a 47% drop from 1440p). The percentage drops are relatively consistent, which implies that the GPU is the primary bottleneck across all resolutions. If the CPU were the limiting factor, we would expect the FPS to remain more stable at lower resolutions, but the data shows a steady decline with resolution, confirming the GPU is the constraint.

The Ultra preset tells the same story more dramatically: 73.2 FPS at 1080p, 46 FPS at 1440p, and 22.3 FPS at 4K. The gap between Medium and High at each resolution is also telling—at 1080p, Medium yields 140.7 FPS while High yields 107.7, a 23% difference. This suggests that the GPU’s shading units and ROPs are the limiting factor, as increasing settings adds more work per pixel. The data clearly shows that this combo is GPU-bound in Fortnite, with the CPU providing sufficient frame pacing at all tested settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo ranks 1206th out of 1564 tested combinations in Fortnite, placing it in the lower-middle tier of all systems tested. This ranking is consistent with the GPU’s 66th percentile standing among all GPUs, but it is lower than the CPU’s 85th percentile, indicating that the GPU is dragging the overall performance down. In a game like Fortnite, which is often CPU-bound at lower settings, this ranking suggests that the Arc B580 is not able to fully utilize the Ryzen 7 3700X’s potential.

Compared to the nearest GPU rivals, the Arc B580’s average benchmark score of 23021 is within 1% of the NVIDIA GeForce RTX 4060 (23181, deltaPct -0.7) and the AMD Radeon 760M (22999, deltaPct 0.1). This means that users can expect similar frame rates to those cards, but the ranking of 1206 out of 1564 is driven by the fact that many other combos use higher-end CPUs or GPUs. The CPU’s nearest rival, the Intel Core i5-12600, has a nearly identical average score (28654 vs 28631, deltaPct -0.1), so swapping the processor for that chip would not meaningfully change the combo’s ranking.

The data suggests that this pairing is a balanced mid-range option, but it is not optimized for high-refresh-rate Fortnite play at 1440p or 4K. The ranking indicates that there are 358 other combos that perform worse, but the majority of tested systems deliver better frame rates, particularly at higher resolutions. For users targeting 1080p gaming, this combo is adequate, but it falls short of the top quartile of test results.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. At 1080p, the Low preset delivers 198.5 FPS, which is ideal for competitive play on a high-refresh-rate monitor. However, the Medium preset still provides a very playable 140.7 FPS while offering better visual quality. The High preset at 107.7 FPS is also viable for most players, but the Ultra preset at 73.2 FPS may be too inconsistent for fast-paced gameplay, though it remains above the 60 FPS threshold.

At 1440p, the Low preset is the only option that delivers a high refresh rate experience, averaging 125 FPS. The Medium preset at 88.8 FPS is still smooth for most gaming scenarios, but the High preset at 71.5 FPS is borderline, and the Ultra preset at 46 FPS is below the 60 FPS target. For 4K gaming, the Low preset at 65.3 FPS is the only playable option, with Medium at 46.1 FPS and High at 37.7 FPS being too choppy for a competitive shooter.

The data indicates that the best experience is achieved by using the Low or Medium preset at 1080p, where the system can maintain frame rates above 140 FPS. At 1440p, the Low preset is the recommended choice for esports-level performance, while at 4K, users should stick to Low settings to avoid severe frame drops. The Ultra preset is not recommended at any resolution, as it consistently produces frame rates below 75 FPS, which is not ideal for Fortnite’s fast-paced action.
