Fortnite

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

The AMD Ryzen 5 5500 presents a six-core, twelve-thread Zen 3 design operating with a 3.60 GHz base clock and a 4.20 GHz boost clock. Its combination of a 16 MB L3 cache and dual-channel DDR4 memory support at 51.2 GB/s bandwidth positions it as a mid-range desktop processor, one that lands in the 79th percentile against all CPUs in the database. In Fortnite, the CPU’s single-thread performance is a critical factor, and the data shows the processor’s 3DMark single-thread score of 836 and Cinebench R23 single-core score of 2319 translate into playable frame rates at lower resolutions where the CPU is more likely to be the limiting component.

At 1920x1080 with Low settings, this combo produces 197.3 FPS average, a figure that indicates the Ryzen 5 5500 can feed the Intel Arc B580 sufficiently when graphical load is minimal. The processor’s multi-threaded capability, demonstrated by a Cinebench R23 multi-core score of 16429 and a Passmark multithread score of 19330, is not heavily taxed in Fortnite, as the game’s Battle Royale mode typically relies more on a few fast cores than on extensive parallel scaling. The 3DMark 2-thread score of 1645 versus the max-thread score of 5411 shows a scaling pattern where doubling the core count yields diminishing returns — a characteristic that aligns with Fortnite’s modest thread utilization.

The Ryzen 5 5500 sits within 0.2% of the Intel Core i5-12500 and AMD Ryzen 5 PRO 4655GE in average benchmark score, with a deltaPct of -0.1 against both, indicating essentially identical compute performance. This parity means the CPU is not the differentiator in this combo’s ranking; rather, the measured FPS results across resolutions and settings reflect how the processor’s six cores handle Fortnite’s engine demands. The 65 W TDP and Socket AM4 compatibility provide context for system builders, but the benchmark evidence points to a CPU that can maintain high frame rates at 1080p, with the GPU taking over as the bottleneck as resolution increases.

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

The measured FPS data for Fortnite with this CPU-GPU combo reveals a clear hierarchy across the four available presets, and the optimal choice depends heavily on the target resolution. At 1920x1080, the Medium preset delivers 138 FPS average, which is a substantial improvement over the High preset’s 105.3 FPS while remaining well above the Ultra preset’s 71.1 FPS. The Low preset at 1080p achieves 197.3 FPS, but this comes at the cost of visual fidelity that many players would find excessive for competitive play.

For 2560x1440, the Medium preset produces 86.7 FPS, which is a more balanced option than High at 66.5 FPS or Ultra at 44.2 FPS. The Low preset at 1440p reaches 124.9 FPS, but again, the visual compromise is significant. At 3840x2160, the situation shifts—Medium drops to 49.9 FPS, which is borderline playable, while High manages 35.5 FPS and Ultra falls to 22.5 FPS, the latter being effectively unplayable for a fast-paced Battle Royale.

The data supports a verdict: Medium is the best experience at 1080p and 1440p, as it preserves frame rates comfortably above 60 FPS while maintaining acceptable visual quality. At 4K, only Low at 65.4 FPS provides a consistently playable experience, though players with lower refresh-rate displays might tolerate Medium at 49.9 FPS. The frame rate gap between Medium and High consistently exceeds 30% across all resolutions, making High a poor value in performance terms, while Ultra’s additional load yields only marginal visual gains for a 48% performance penalty at 1080p compared to High.

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

The measured FPS scaling across resolutions provides strong evidence of where the bottleneck shifts in this combo. At Low settings, the average frame rate drops from 197.3 FPS at 1080p to 124.9 FPS at 1440p, a reduction of 36.7%, and then to 65.4 FPS at 4K, a further reduction of 47.6% from the 1440p figure. This steep decline indicates that the Intel Arc B580 is the primary limiting factor at higher resolutions, as the CPU’s six cores are not being saturated when the GPU’s rendering load increases.

At Medium settings, the scaling is similar: 138 FPS at 1080p falls to 86.7 FPS at 1440p (a 37.2% drop) and then to 49.9 FPS at 4K (a 42.4% drop from 1440p). The consistent ~37% reduction between 1080p and 1440p across Low and Medium presets points to a GPU-bound scenario at these settings, as the pixel count increases by 78% while frame rates fall by roughly a third, suggesting the Arc B580’s 12 GB GDDR6 memory and 456.0 GB/s bandwidth are being utilized effectively but have finite limits.

The High preset shows a different pattern: 105.3 FPS at 1080p drops to 66.5 FPS at 1440p (a 36.9% drop) and then to 35.5 FPS at 4K (a 46.6% drop from 1440p). The 4K figure being less than half of the 1440p figure indicates that the GPU’s shading units—2560 in the Arc B580—are overwhelmed by the combination of higher resolution and more demanding graphical effects. The FPS at 4K High (35.5) is slightly above the 4K Ultra figure (22.5), but both are below the threshold for smooth gameplay, confirming that Fortnite at 4K is not a viable option for this combo beyond Low settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of AMD Ryzen 5 5500 and Intel Arc B580 ranks 1224 out of 1564 tested combos in Fortnite, placing it in the lower portion of the database’s results. This rank, which corresponds to roughly the 22nd percentile of all tested CPU-GPU pairings, may seem counterintuitive given the respectable frame rates at 1080p Low and Medium, but it reflects the fact that the database includes many higher-end configurations that achieve far superior performance at higher resolutions and settings.

The rank indicates that while this combo is functional for casual play, it is not competitive with the majority of tested combinations in the database. The CPU’s 79th percentile standing and the GPU’s 66th percentile standing both suggest mid-pack components, yet their combined performance in Fortnite lags behind what the individual component rankings might imply. This discrepancy arises because Fortnite’s performance is highly sensitive to both CPU single-thread speed and GPU rasterization throughput, and neither component excels in its respective category.

The GPU’s nearest rival, the NVIDIA GeForce RTX 4060, shows a deltaPct of -0.7, meaning the Arc B580 scores 0.7% lower in average benchmark score—a negligible difference that does not explain the combo’s low rank. Similarly, the CPU’s near-identical performance to the Intel Core i5-12500 (deltaPct -0.1) suggests that the combo’s ranking is not due to a weak processor. The 1224th rank out of 1564 combos implies that many tested pairings include higher-tier GPUs or CPUs that push frame rates far beyond what this combo achieves, particularly at 1440p and 4K where the Arc B580’s mid-range positioning becomes evident.

Q: Why is the combo rank so low despite decent 1080p performance?

A: The combo ranks 1224 out of 1564 tested combinations because the database includes many higher-tier pairings that achieve significantly higher frame rates at higher resolutions. The 1080p Low result of 197.3 FPS is respectable, but the 4K High figure of 35.5 FPS drags the overall assessment down.

Q: Is the Ryzen 5 5500 a bottleneck for the Arc B580 in this game?

A: At 1080p Low, the CPU can drive 197.3 FPS, suggesting it is not a bottleneck at that setting. However, at higher resolutions, the frame rate drops are primarily due to GPU limits, as evidenced by the consistent scaling patterns across all presets.

Q: How does the Arc B580 compare to its nearest rival in benchmark scores?

A: The Arc B580’s average benchmark score of 23021 is 0.7% lower than the NVIDIA GeForce RTX 4060’s score of 23181, and 0.1% higher than the AMD Radeon 760M’s 22999. This indicates near-identical compute performance among these GPUs.

Q: What frame rate can I expect at 1440p with High settings?

A: The measured data shows 66.5 FPS average at 2560x1440 with High settings, which is playable but below the 90 FPS threshold that many players prefer for competitive Fortnite play.

Q: Does the Ultra preset offer any benefit over High for this combo?

A: No. At 1080p, Ultra produces 71.1 FPS versus High’s 105.3 FPS, a 32.5% performance penalty. At 4K, Ultra falls to 22.5 FPS, which is unplayable, while High manages 35.5 FPS. The visual difference does not justify the frame rate loss.

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

At 1920x1080, the measured average frame rates are as follows: Low settings produce 197.3 FPS, Medium produces 138 FPS, High produces 105.3 FPS, and Ultra produces 71.1 FPS. This progression shows a consistent degradation of approximately 30-35% with each step up in preset, reflecting the increasing demand on the Arc B580’s 2560 shading units and 80 ROPs.

At 2560x1440, the average frame rates are: Low at 124.9 FPS, Medium at 86.7 FPS, High at 66.5 FPS, and Ultra at 44.2 FPS. The 1440p figures represent a 36-38% reduction from the corresponding 1080p values for Low, Medium, and High, while Ultra shows a slightly larger drop of 37.8%, indicating that the GPU’s texture rate of 427.2 GTexel/s becomes a limiting factor at the highest preset.

At 3840x2160, the average frame rates are: Low at 65.4 FPS, Medium at 49.9 FPS, High at 35.5 FPS, and Ultra at 22.5 FPS. The 4K Low figure is the only one above 60 FPS, and even that is marginal. The 4K Medium result of 49.9 FPS is below the 60 FPS threshold, and the 4K High and Ultra figures are well below playable levels for a competitive Battle Royale. The 4K data confirms that this combo is not suited for high-refresh-rate 4K play, with the GPU’s 456.0 GB/s memory bandwidth being insufficient to maintain smooth frame rates at this resolution with demanding presets.

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

The Intel Arc B580 is built on the Xe2-HPG architecture with the BMG-G21 chip, fabricated on a 5 nm process at TSMC with 19,600 million transistors. Its 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is a substantial amount for a mid-range GPU and proves adequate for Fortnite’s texture streaming at 1080p and 1440p Medium settings. The GPU’s base and boost clocks are both 2670 MHz, with memory operating at 2375 MHz (19 Gbps effective), and its 13.67 TFLOPS FP32 performance places it in the 66th percentile of all GPUs.

In Fortnite, the Arc B580’s 2560 shading units and 160 TMUs handle the game’s rendering efficiently at lower presets, as evidenced by the 197.3 FPS result at 1080p Low. However, the GPU’s performance collapses at 4K Ultra, where the 22.5 FPS average indicates that the 80 ROPs are insufficient for the pixel throughput required at that resolution with full graphical effects. The GPU’s 213.6 GPixel/s pixel rate is the key constraint at 4K, as the increasing pixel count from 1080p to 4K (a 4x increase) outstrips what the ROPs can deliver.

The Arc B580’s benchmark scores, including a Passmark G3D score of 15748 and a 3DMark Steel Nomad DX12 score of 3068, position it as a capable performer for 1080p and 1440p gaming. Its nearest rival, the NVIDIA GeForce RTX 4060, scores 23181 in average benchmark, just 0.7% higher, yet in Fortnite the Arc B580’s performance at 1440p High (66.5 FPS) suggests that driver optimizations and game-specific engine quirks play a significant role. The GPU’s 190 W TDP and dual-slot design with a single 8-pin power connector make it a practical choice for mid-range systems, but the measured FPS data shows that its capabilities are best utilized at 1080p Medium or 1440p Low for consistently smooth gameplay.
