Fortnite

Intel Core Ultra 7 270K Plus paired with Intel Arc B390 delivers a playable but heavily GPU-bound Fortnite experience, with the data showing a clear ceiling imposed by the integrated graphics solution. The combo ranks near the bottom of the tested field, and the frame rate scaling across resolutions confirms that the CPU is never the limiting factor in this configuration.

Resolution Scaling

The measured data reveals a steep and consistent frame rate penalty as resolution increases, which is the signature of a system constrained by its graphics processor rather than its central processor. At Low settings, the average frame rate drops from 115 FPS at 1920x1080 to 73 FPS at 2560x1440, a reduction of 42 FPS, and then plummets to 39 FPS at 3840x2160, which is 34 FPS lower than the 1440p result. This represents a 66% decrease in performance from 1080p to 4K, indicating that the GPU is being saturated well before the CPU's capabilities are taxed.

The scaling pattern is even more pronounced at higher quality presets. With High settings, the average frame rate falls from 63 FPS at 1080p to 40 FPS at 1440p, then to 21 FPS at 4K. The delta between 1440p and 4K is 19 FPS, which is nearly the same as the 23 FPS delta between 1080p and 1440p, showing that the performance loss is not linear but becomes progressively worse as pixel count increases. This non-linear degradation points to the GPU hitting its memory bandwidth and shading limits, as the Arc B390 relies on system shared memory and has a modest 1536 shading units.

At Medium settings, the data shows 81 FPS at 1080p, 51 FPS at 1440p, and 27 FPS at 4K. The 4K result includes the only recorded minimum and maximum frame rate values for that resolution, with a spread from 23 FPS to 31 FPS, which shows a tight range that indicates consistent, albeit low, performance without major stuttering. The Ultra preset produces the lowest numbers across the board: 41 FPS at 1080p, 26 FPS at 1440p, and 14 FPS at 4K, with the 4K result falling below the threshold for smooth gameplay.

The overall trend makes it clear that the Arc B390 is the bottleneck. The CPU, with its 24 cores and 24 threads, is capable of far higher frame rates, as evidenced by the 115 FPS result at 1080p Low, which is still likely below what the processor could deliver if paired with a faster discrete GPU. The data suggests that users targeting 1080p will find the performance acceptable at Low and Medium presets, but 1440p and 4K gaming will require significant compromises in visual quality to maintain playable frame rates.

How This Combo Ranks

This combination of CPU and GPU sits at the very bottom of the performance hierarchy for Fortnite, with a combo rank of 2417 out of 2740 tested combinations. This places it in the bottom 12% of all tested systems, which is a stark contrast to the CPU's individual standing. The Intel Core Ultra 7 270K Plus, on its own, is a top-tier processor with a percentile ranking of 96 against all CPUs, meaning it outperforms 96% of all tested processors. The GPU, however, drags the entire combo down.

The Arc B390's individual benchmark score is 1482 in 3DMark Steel Nomad DX12, which puts it in the 9th percentile of all GPUs. This is an extremely low score, and the nearest rivals in the database are all legacy NVIDIA parts: the GeForce GT 520MX with a score of 1463 (1.3% behind), the GeForce 800M with 1460 (1.5% behind), the GeForce GT 625 OEM with 1446 (2.5% behind), and the GeForce GT 710 with 1443 (2.7% behind). The Arc B390 is only marginally faster than these decade-old entries, which explains why the combo rank is so poor despite the powerful CPU.

The disparity between the CPU and GPU performance is the defining characteristic of this combo. The processor belongs in the company of server-class chips; its nearest rivals include the Intel Xeon 6520P with an average score of 93786 (0% delta), the AMD EPYC 4564P with 95183 (-1.5%), the AMD EPYC 9175F with 95615 (-1.9%), and the AMD EPYC 4565P with 95764 (-2.1%). This is workstation and server territory, yet the GPU is competing with entry-level mobile parts from over a decade ago.

The data indicates that this combo is severely unbalanced for gaming. The CPU provides immense headroom that the GPU cannot utilize, resulting in a system that performs like a low-end machine in Fortnite despite having a flagship-class processor. For the 2740 tested combinations, this pairing is an outlier in terms of the performance gap between its components, and the resulting rank reflects that imbalance.

GPU Role

The Intel Arc B390 is the dominant performance limiter in this combo, and its specifications explain why. It is based on the Xe3-LPG architecture on a 3 nm process node, but it is an integrated graphics processor (IGP) rather than a discrete card, which fundamentally constrains its capabilities. The GPU has 1536 shading units, 48 texture mapping units, and 24 raster operations units, along with 12 ray tracing cores, but these are paired with shared system memory rather than dedicated VRAM.

The memory configuration is the most critical limitation. The Arc B390 uses "System Shared" memory with a "System Dependent" bandwidth, meaning it has no dedicated video memory of its own. This forces the GPU to compete with the CPU for access to the same DDR5 memory pool, which is a major bottleneck for a game like Fortnite that requires frequent texture streaming and data transfers. The lack of dedicated VRAM means that higher resolutions and quality settings will quickly exhaust the available memory bandwidth, causing the dramatic frame rate drops seen in the measured data.

The clock speeds are also modest, with a base clock of 300 MHz and a boost clock of 2500 MHz. The boost clock is respectable for an integrated solution, but the low base clock suggests that the GPU spends much of its time at lower frequencies under sustained load. The compute throughput is rated at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16, which are low figures compared to modern discrete GPUs, and the pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are insufficient for high-resolution gaming.

The GPU's benchmark results confirm its position. The 3DMark Steel Nomad DX12 score of 1482 is in the 9th percentile of all GPUs, and its nearest rivals are all low-end parts from previous generations. The power draw is listed at 80 W, which is low, but this does not compensate for the lack of compute and memory resources. The Arc B390 is simply not designed for demanding titles like Fortnite at high settings, and the measured frame rates reflect this reality.

Measured FPS Breakdown

The measured frame rates show a consistent pattern across all resolutions, with Low settings providing the best performance and Ultra providing the worst. At 1920x1080, the Low preset delivers an average of 115 FPS, which is the highest recorded result in the entire dataset. Medium follows at 81 FPS, with a minimum of 69 and a maximum of 93, showing a stable frame time distribution. High drops to 63 FPS, while Ultra falls to 41 FPS, which is below the 60 FPS target for smooth competitive play.

Moving to 2560x1440, the performance drops significantly. Low settings produce 73 FPS, Medium produces 51 FPS with a range of 44 to 59, High produces 40 FPS, and Ultra produces 26 FPS. The gap between Low and Ultra at this resolution is 47 FPS, which is a massive difference that highlights how sensitive this GPU is to quality changes. None of the 1440p presets reach the 60 FPS threshold except for Low, and even that result is barely above it.

At 3840x2160, the situation becomes dire. Low settings yield 39 FPS, Medium yields 27 FPS with a range of 23 to 31, High yields 21 FPS, and Ultra yields 14 FPS. These numbers are all below the minimum playable threshold for a fast-paced battle royale game, and the 4K Ultra result of 14 FPS is essentially a slideshow. The data shows that 4K is not a viable resolution for this combo, regardless of settings, as even the lowest quality preset cannot reach 40 FPS.

The frame rate ranges recorded at Medium settings provide some insight into consistency. At 1080p, the range is 69 to 93 FPS, which is a 24 FPS spread. At 1440p, the range narrows to 44 to 59 FPS, a 15 FPS spread. At 4K, the range is 23 to 31 FPS, an 8 FPS spread. This shows that as the GPU becomes more saturated, the frame times become more consistent, but this is a sign of the GPU being fully maxed out rather than a sign of efficiency.

Settings Recommendations

Based solely on the measured data, the Low preset at 1920x1080 is the only configuration that delivers a clearly competitive experience, with an average of 115 FPS. This is the recommended setup for players who prioritize frame rate and responsiveness, as it provides a large margin above the 60 FPS target and should minimize input lag. The Medium preset at 1080p, with 81 FPS, is also viable and offers better visual quality while still maintaining a comfortable frame rate above 60.

For players who prefer higher visual fidelity, the High preset at 1080p yields 63 FPS, which is just above the 60 FPS threshold. This is a borderline recommendation, as the average is close enough to the target that dips below it could occur in heavy combat scenarios. The Ultra preset at 1080p, with 41 FPS, is not recommended for competitive play, as the frame rate is too low for fast reactions.

At 2560x1440, the Low preset is the only acceptable option, with 73 FPS. This is above 60 FPS and could be used by players with 1440p monitors, but the visual quality will be significantly reduced. The Medium preset at 1440p, with 51 FPS, is below the 60 FPS target and may cause noticeable stutter in action-heavy moments. High and Ultra at this resolution are not recommended, with 40 FPS and 26 FPS respectively.

At 3840x2160, no settings preset is recommended for normal play, as even the Low preset only reaches 39 FPS. Players with 4K displays should run the game at a lower resolution or accept that this combo cannot deliver a playable frame rate at native 4K. The data clearly indicates that this system is best suited to 1080p gaming with Low or Medium settings, and any attempt to push higher resolutions or quality levels will result in a subpar experience.

CPU Role

The Intel Core Ultra 7 270K Plus is a high-end desktop processor that is entirely underutilized in this combo. It has 24 cores and 24 threads, with a base clock of 3.70 GHz and a boost clock of 5.50 GHz. The processor is built on a 3 nm process node and features a large cache hierarchy: 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. This configuration is designed for heavy multi-threaded workloads, as shown by its benchmark scores.

The CPU's benchmark results are impressive. It scores 44253 in Cinebench R23 multi-core and 2439 in single-core, which are strong numbers for a desktop processor. In PassMark tests, it achieves a multi-thread score of 68574 and a single-thread score of 5068. The average benchmark score of 93785 places it in the 96th percentile of all CPUs, and its nearest rivals are server-grade processors like the Intel Xeon 6520P and AMD EPYC series. This is a processor that can handle any game or productivity task without breaking a sweat.

Despite this, the measured Fortnite frame rates show no signs of CPU limitation. The frame rates scale almost entirely with resolution and settings, which is the expected behavior when the GPU is the bottleneck. The CPU's role is to feed the GPU with draw calls and game logic, and at 1080p Low, the 115 FPS result is likely still below what the CPU could deliver. The CPU has headroom to spare, but the Arc B390 cannot take advantage of it.

The memory support for this CPU is DDR5 with a dual-channel bus and a bandwidth of 115.2 GB/s. This is a high-bandwidth configuration for a desktop processor, but the GPU's reliance on system shared memory means it is competing with the CPU for this bandwidth. In a system with a discrete GPU, the CPU's memory bandwidth would be used solely for system tasks, but here it must also serve the GPU, which could limit the CPU's own performance in memory-intensive scenarios.

The CPU's 20 PCIe Gen 5 lanes are not relevant for an integrated GPU, as the Arc B390 uses the system bus rather than a dedicated PCIe connection. The processor is unlocked for overclocking, which could potentially boost performance, but the GPU would still be the limiting factor. The data shows that this CPU is far more capable than the GPU allows it to be in Fortnite, making it a poor pairing for this particular game.
