# Fortnite with Intel Core Ultra 5 245 + Intel Arc B580

The Intel Core Ultra 5 245 pairs with the Intel Arc B580 to deliver a 1080p-focused Fortnite experience that scales predictably across resolutions and settings. The CPU, a 14-core Arrow Lake-S part with a 5.10 GHz boost clock, sits at the 90th percentile among all tested CPUs, while the Arc B580, a Battlemage-generation GPU with 12 GB of GDDR6 memory, ranks at the 68th percentile. In this specific combination, the pairing ranks 2032nd out of 2740 tested combos for Fortnite, placing it in the lower-middle portion of the database. The measured frame rates tell a clear story: playable at 1440p with medium settings, excellent at 1080p with low settings, but struggling at 4K with high or ultra presets.

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

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor built on the Arrow Lake architecture with a 3.50 GHz base clock and a 5.10 GHz boost clock. It uses a 3 nm process from TSMC and supports DDR5 memory through a dual-channel interface with 102.4 GB/s of bandwidth. The CPU's 24 MB of shared L3 cache and 3 MB per-core L2 cache provide ample data locality for game logic and physics calculations typical of a battle royale title like Fortnite.

In synthetic benchmarks, this CPU achieves a Cinebench R23 multi-core score of 32,924 and a single-core score of 4,648. The PassMark multi-thread score of 38,706 and single-thread score of 4,394 further characterize its performance profile. These scores place the Ultra 5 245 at the 90th percentile against all CPUs, with an average benchmark score of 48,995. Its nearest rivals in aggregate performance include the AMD Ryzen 7 PRO 5755G (0.4% higher score), the AMD Ryzen 9 7900 (0.5% higher), the Intel Xeon Gold 5318H (0.6% lower), and the Intel Core i5-14600K (0.8% lower). The deltas here are remarkably tight—all within one percent—indicating that the Ultra 5 245 sits in a densely packed performance tier.

For Fortnite specifically, the CPU's role is most apparent at lower resolutions and settings where the GPU is not the primary bottleneck. At 1080p with low settings, the combo delivers 200 FPS average, which is the highest measured result across all configurations. This suggests the 14 cores and 5.10 GHz boost clock are sufficient to feed the Arc B580 at this resolution without creating a significant CPU limitation. The CPU's PassMark physics score of 2,569 and data compression score of 400,942 indicate solid computational throughput for game simulation tasks.

However, the CPU's locked multiplier (multiplierUnlocked is false) means users cannot overclock to extract additional performance, though the stock boost clock already reaches 5.10 GHz. The 65 W TDP suggests efficient operation, and the integrated Arc Xe-LPG Graphics 64EU provides a fallback display output, though the discrete Arc B580 handles all gaming workloads here. The CPU's PCIe Gen 5 support with 20 lanes ensures the GPU has sufficient bandwidth, though the Arc B580 itself uses a PCIe 4.0 x8 interface.

Q: What is the best resolution and settings combination for this CPU-GPU pair in Fortnite?

A: The data shows 1920x1080 with Low settings achieves the highest measured average FPS at 200, while 2560x1440 with Low settings reaches 127 FPS average. For a balance of visual quality and performance, 1920x1080 with Medium settings delivers 141 FPS average with a minimum of 120 FPS.

Q: How does this combo rank among all tested Fortnite configurations?

A: This pairing ranks 2032nd out of 2,740 tested combos for Fortnite, placing it in the lower-middle portion of the database. The ranking reflects the GPU's 68th percentile standing among all GPUs rather than the CPU's stronger 90th percentile.

Q: Is the Intel Arc B580's 12 GB VRAM sufficient for Fortnite at 4K?

A: The 12 GB of GDDR6 memory on a 192-bit bus with 456.0 GB/s bandwidth is not the limiting factor at 4K. The measured data shows 4K Ultra averages only 24 FPS, while 4K Low reaches 67 FPS, indicating that raw GPU compute throughput, not VRAM capacity, determines the outcome.

Q: How does the Arc B580 compare to its nearest GPU rivals in aggregate benchmarks?

A: The Arc B580's average benchmark score is 23,021. The AMD Radeon RX 580 2048SP scores 0.2% higher, the NVIDIA GeForce RTX 2080 scores 0.6% higher, the NVIDIA GeForce RTX 3080 scores 0.7% higher, and the NVIDIA P106-100 scores 1% higher. All deltas are within one percent.

Q: What frame rates can a user expect at 1440p with Medium settings?

A: The measured data shows 2560x1440 with Medium settings produces an average of 89 FPS, with a minimum of 76 FPS and a maximum of 103 FPS. This is the only 1440p configuration with recorded min/max values, indicating a stable frame time distribution.

Q: Does the CPU's 14-core configuration provide any advantage at high frame rates?

A: At 1080p with Low settings, the combo reaches 200 FPS average, which is the ceiling of the measured data. The CPU's 14 cores and 14 threads, combined with its 90th percentile standing, suggest it is not the bottleneck at this frame rate, though the exact core utilization in Fortnite is not disclosed in the data.

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

The measured FPS data reveals a clear pattern of GPU-bound scaling across resolutions. At 1080p with Low settings, the combo achieves 200 FPS average. Moving to 1440p at the same Low settings drops the average to 127 FPS, a reduction of 73 FPS (approximately 36.5% lower). At 4K with Low settings, the average falls to 67 FPS, which is 133 FPS below the 1080p result—a 66.5% decrease. This steep decline across resolutions indicates that the Arc B580's rendering throughput is the primary limiting factor, as the CPU's performance headroom at lower resolutions does not compensate for the increased pixel count.

The same scaling pattern holds for Medium settings. At 1080p, Medium averages 141 FPS; at 1440p, it drops to 89 FPS (52 FPS lower); and at 4K, it falls to 47 FPS (94 FPS lower than 1080p). The High preset shows a similar trajectory: 109 FPS at 1080p, 69 FPS at 1440p, and 37 FPS at 4K. The Ultra preset is the most demanding, with 72 FPS at 1080p, 46 FPS at 1440p, and 24 FPS at 4K.

The resolution scaling data strongly suggests that the GPU, not the CPU, is the bottleneck in this combination. The Arc B580's 13.67 TFLOPS of FP32 compute and 213.6 GPixel/s pixel rate are simply insufficient to maintain high frame rates at 4K, particularly with higher quality settings. The CPU's performance, as measured by its 90th percentile ranking, would likely support higher frame rates if the GPU could render them. The fact that 1080p Low reaches 200 FPS—the highest measured value—while 4K Ultra languishes at 24 FPS underscores this GPU-bound conclusion.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Intel Core Ultra 5 245 combined with the Intel Arc B580 ranks 2032nd out of 2,740 tested combos for Fortnite. This places the pairing in the 74th percentile from the bottom (or 26th percentile from the top), meaning roughly three-quarters of tested configurations deliver better Fortnite performance. The ranking reflects the Arc B580's relatively modest standing among GPUs—its 68th percentile places it below many mid-range and high-end graphics cards—while the CPU's 90th percentile ranking is effectively neutralized by the GPU limitation.

The CPU's nearest rivals in aggregate benchmark scores include the AMD Ryzen 7 PRO 5755G (0.4% higher), AMD Ryzen 9 7900 (0.5% higher), Intel Xeon Gold 5318H (0.6% lower), and Intel Core i5-14600K (0.8% lower). These sub-one-percent deltas suggest that swapping the Ultra 5 245 for any of these CPUs would produce nearly identical Fortnite results when paired with the same GPU. The GPU's nearest rivals—the AMD Radeon RX 580 2048SP (0.2% higher), NVIDIA GeForce RTX 2080 (0.6% higher), NVIDIA GeForce RTX 3080 (0.7% higher), and NVIDIA P106-100 (1% higher)—similarly indicate that the Arc B580 performs within one percent of these cards in aggregate benchmarks.

Given the combo's 2032nd rank out of 2,740, the data indicates that users seeking higher Fortnite frame rates should prioritize a more powerful GPU rather than a different CPU. The Ultra 5 245's strong synthetic performance does not translate into a high combo ranking because the Arc B580's rendering capacity caps the achievable frame rates, particularly at higher resolutions and settings.

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

The Intel Arc B580 is built on the Xe2-HPG architecture (Battlemage generation) using a 5 nm process from TSMC. It features 2,560 shading units, 160 texture mapping units, and 80 render output units, along with 20 ray tracing cores. The GPU operates at a base clock of 2670 MHz and a boost clock of 2670 MHz, with memory running at 2375 MHz (19 Gbps effective). The 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is substantial for the GPU's performance class.

The Arc B580's compute capabilities include 13.67 TFLOPS of FP32 performance and 27.34 TFLOPS of FP16 (2:1 ratio). Its pixel rate is 213.6 GPixel/s, and its texture rate is 427.2 GTexel/s. In synthetic benchmarks, the GPU scores 3,068 in 3DMark Steel Nomad DX12, 92,821 in Geekbench OpenCL, and 109,672 in Geekbench Vulkan. The PassMark G3D score of 15,748 and GPU compute score of 7,729 further characterize its performance. The GPU's average benchmark score is 23,021, placing it at the 68th percentile among all GPUs.

In Fortnite, the Arc B580's performance is consistent with its synthetic standing. The GPU's 12 GB VRAM is never a limiting factor, as even the most demanding 4K Ultra setting (24 FPS average) does not indicate memory capacity issues. Instead, the GPU's raw compute throughput determines the frame rates. The 2670 MHz boost clock and 456.0 GB/s bandwidth are well-suited for 1080p and 1440p gaming, where the measured results show playable frame rates across most settings. The GPU's 190 W TDP and suggested 450 W PSU indicate moderate power requirements, and its dual-slot design with one 8-pin power connector fits standard cases.

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

At 1920x1080, the measured average FPS values are: Low 200, Medium 141, High 109, and Ultra 72. The Medium preset also includes recorded minimum and maximum values of 120 and 162 FPS, respectively, indicating a stable frame rate range. The spread from Low to Ultra is 128 FPS, with Ultra delivering only 36% of the Low preset's performance. This demonstrates that the Arc B580's rendering load increases dramatically with higher quality settings even at 1080p.

At 2560x1440, the average FPS values are: Low 127, Medium 89, High 69, and Ultra 46. The Medium preset records a minimum of 76 FPS and a maximum of 103 FPS. The transition from 1080p to 1440p reduces frame rates by 28-36% across all settings, with the Low preset dropping from 200 to 127 FPS (a 73 FPS reduction) and Ultra dropping from 72 to 46 FPS (a 26 FPS reduction). The 1440p results remain playable for Low and Medium settings, while High and Ultra fall below the 60 FPS threshold.

At 3840x2160, the average FPS values are: Low 67, Medium 47, High 37, and Ultra 24. The Medium preset records a minimum of 40 FPS and a maximum of 54 FPS. At 4K, only the Low preset achieves a playable average above 60 FPS, and even that is only marginally so. The Ultra preset at 24 FPS average is effectively unplayable for competitive gameplay. The scaling from 1080p to 4K at each setting shows a consistent pattern: Low drops 66.5%, Medium drops 66.7%, High drops 66.1%, and Ultra drops 66.7%. This uniform reduction across settings confirms that the GPU's pixel throughput is the dominant constraint.

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

For users targeting 1080p, the Medium preset provides the best balance of visual quality and performance. The measured 141 FPS average with a 120 FPS minimum ensures smooth gameplay even during intense combat scenes, while the High preset at 109 FPS average is also acceptable for most players. The Ultra preset at 72 FPS average is playable but sacrifices significant frame rate for marginal visual gains. The Low preset at 200 FPS is optimal for competitive players who prioritize maximum responsiveness over visual fidelity.

At 1440p, the Low preset at 127 FPS average is the recommended choice for competitive play, while the Medium preset at 89 FPS average with a 76 FPS minimum offers a good visual upgrade without dropping below playable thresholds. The High preset at 69 FPS average is borderline, and the Ultra preset at 46 FPS average is not recommended for smooth gameplay. Users with 1440p monitors should stick to Low or Medium settings to maintain frame rates above 60 FPS.

At 4K, the data shows that only the Low preset at 67 FPS average provides a playable experience, and even that is marginal. The Medium preset at 47 FPS average and High preset at 37 FPS average are below the 60 FPS target, while the Ultra preset at 24 FPS average is unsuitable for action-oriented gameplay. For 4K users, the Low preset is the only viable option, and even then, the experience will be less smooth than at lower resolutions. Overall, the best experience per the measured rows is 1080p with Medium settings, which delivers 141 FPS average with a 120 FPS minimum and a 162 FPS maximum, providing both visual quality and performance headroom.
