Fortnite

The Intel Core i7-14700K paired with the Intel Arc B370 presents a stark study in component imbalance within Fortnite. The data indicates a configuration where a top-tier 20-core processor is bottlenecked by an entry-level integrated Graphics-M part, resulting in a combo rank of 2517 out of 2740 tested combinations. This analysis examines how the CPU’s architectural strengths are neutralized by the GPU’s limited throughput, with benchmark results showing that frame rates are primarily dictated by resolution and graphical preset rather than the processor’s capabilities.

CPU Role

The Intel Core i7-14700K is specified with 20 cores and 28 threads, a configuration built on the Raptor Lake architecture using a 10 nm process. Its base clock is 3.40 GHz with a boost clock of 5.60 GHz. The processor includes an L3 cache of 33 MB shared across the cores, with 80 KB of L1 and 2 MB of L2 per core. In synthetic workloads, this CPU demonstrates strong multi-threaded performance, scoring 33,440.5 in Cinebench R23 multi-core and 18,544 in Cinebench R20 multi-core. Single-thread performance is also robust, with a Cinebench R23 single-core score of 2,160 and a Geekbench single-core score of 2,569. This positions the processor in the 94th percentile among all CPUs, with an average benchmark score of 69,355. Its nearest rival, the AMD Ryzen 9 7950X, scores 69,515, a delta of -0.2%, indicating the i7-14700K is essentially performance-equivalent to that flagship chip in general workloads.

However, in Fortnite, the CPU’s potential is largely unrealized. The measured FPS data shows that at 1080p Low settings, the average frame rate is 104 FPS. While this is the highest result in the dataset, it falls far short of what the CPU alone could theoretically support. The bottleneck is the GPU, which restricts output to a fraction of what the i7-14700K could feed. The CPU’s high boost clock of 5.60 GHz is relevant for maintaining minimum frame rates, but the measured data does not include 1% lows for most settings, making it difficult to isolate CPU-related frame pacing issues. The processor’s role in this game is to calculate game logic, physics, and draw calls, but with the Arc B370 delivering only 6.144 TFLOPS of FP32 performance, it cannot generate enough frames to stress the CPU’s capabilities. The data suggests that the i7-14700K is operating far below its utilization ceiling, effectively idling while waiting for the GPU to render each frame.

FAQ

Q: Why does the Intel Core i7-14700K, which ranks in the 94th percentile, not produce higher frame rates in Fortnite?

A: The processor’s high percentile ranking reflects its performance in synthetic benchmarks like Cinebench and Geekbench. However, the measured FPS data shows that the Intel Arc B370 GPU is the limiting factor. For example, at 1080p Low, the average is 104 FPS, but the GPU’s 3DMark Steel Nomad score of 1,184 places it in the 5th percentile, indicating it cannot render frames fast enough to utilize the CPU’s power.

Q: How does the i7-14700K compare to its nearest rival, the AMD Ryzen 9 7950X?

A: The data shows the i7-14700K has an average benchmark score of 69,355, while the Ryzen 9 7950X scores 69,515. This represents a delta of -0.2%, meaning the Intel processor is statistically tied with the AMD chip in overall performance. This parity does not translate to a meaningful difference in Fortnite because the GPU bottleneck dominates the frame rate.

Q: Is the Arc B370’s performance comparable to any other GPUs in the database?

A: The Arc B370’s average benchmark score is 1,184. Its nearest rival is the ATI Radeon HD 5770 with a score of 1,190, a delta of -0.5%. This places the Intel GPU in the 5th percentile of all GPUs, showing it is an entry-level part that struggles with modern game rendering loads.

Q: What is the impact of the CPU’s 28 threads on Fortnite’s measured performance?

A: Fortnite’s frame rate is not scaling with the CPU’s thread count. The highest average FPS recorded is 104 at 1080p Low. Since the GPU’s rendering throughput is the primary constraint, the 28 threads remain largely idle. The CPU’s strong multi-core scores, such as 33,440.5 in Cinebench R23, do not translate to higher FPS in this specific configuration.

Q: Does the CPU’s boost clock of 5.60 GHz help in any measured scenario?

A: The boost clock is a high figure, but its benefit cannot be observed in the data because the GPU limits output. The highest 4K result is 35 FPS at Low settings, which is a GPU-bound scenario. Without 1% low data for most rows, it is not possible to attribute any frame time improvements to the CPU’s clock speed.

Q: Why does the combo rank at 2517 out of 2740 despite having a top-tier CPU?

A: The combo rank reflects the entire system’s performance in Fortnite. The Arc B370 GPU, with a 5th percentile ranking, drags the overall result down. The data shows that even at 1080p High, the average FPS is 57, which is below the threshold for smooth competitive play, demonstrating that the GPU is the primary reason for the low combo rank.

Resolution Scaling

The measured FPS data reveals a consistent and predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate drops from 104 FPS at 1080p to 66 FPS at 1440p, and finally to 35 FPS at 4K. This represents a 66% reduction in frame rate from 1080p to 4K. For High settings, the decline is from 57 FPS at 1080p to 36 FPS at 1440p, and 19 FPS at 4K, a 67% drop. Medium settings show a similar trend, with 73 FPS at 1080p, 46 FPS at 1440p, and 25 FPS at 4K.

This scaling behavior indicates a system that is entirely GPU-limited. If the CPU were the bottleneck, the frame rate would remain relatively flat across resolutions, as the processor’s workload does not change significantly with pixel count. Instead, the steep decline in FPS as resolution increases points directly to the Arc B370’s limited pixel throughput. The GPU’s pixel rate is specified at 48.00 GPixel/s, and its memory bandwidth is listed as "System Dependent," which likely hampers performance at higher resolutions. The data shows that at 4K Ultra, the average FPS falls to 13, which is nearly unplayable. The scaling from 1440p to 4K at Ultra settings is a 46% drop (from 24 to 13 FPS), while the drop from 1080p to 1440p at Ultra is 35% (from 37 to 24 FPS). These percentages highlight that the GPU’s rendering capacity is exhausted quickly, and the frame rate is directly proportional to the number of pixels the GPU must process.

Measured FPS Breakdown

At 1920x1080, the data shows a clear hierarchy across settings. Low settings yield an average of 104 FPS, which is the highest frame rate in the entire test suite. Medium settings produce an average of 73 FPS, with a minimum of 62 and a maximum of 84 FPS. High settings drop to an average of 57 FPS, and Ultra settings further reduce the average to 37 FPS. The gap between Low and Ultra at 1080p is 67 FPS, illustrating the significant cost of higher graphical fidelity on this GPU.

Moving to 2560x1440, the frame rates decrease substantially. Low settings average 66 FPS, which is a 36% reduction from the 1080p Low result. Medium settings average 46 FPS, with a minimum of 39 and a maximum of 53 FPS. High settings average 36 FPS, and Ultra settings average 24 FPS. The spread between Low and Ultra at 1440p is 42 FPS, showing a compressed range as the GPU becomes more constrained.

At 3840x2160, the performance is marginal. Low settings average 35 FPS, which is the only 4K result above 30 FPS. Medium settings average 25 FPS, with a minimum of 21 and a maximum of 28 FPS. High settings average 19 FPS, and Ultra settings average 13 FPS. The difference between Low and Ultra at 4K is only 22 FPS, indicating that the GPU is operating at its absolute limit, and preset changes have diminishing returns on frame rate. The minimum FPS data available for Medium settings shows 21 FPS at 4K, 39 FPS at 1440p, and 62 FPS at 1080p, which provides some insight into frame pacing stability.

GPU Role

The Intel Arc B370 is an integrated GPU based on the Xe3-LPG architecture, built on a 3 nm process. It features 1,280 shading units, 40 texture mapping units, and 20 raster output units, with 10 ray tracing cores. Its boost clock is 2,400 MHz, and it relies on "System Shared" memory, meaning it uses the system’s main memory rather than dedicated VRAM. This configuration results in a memory bandwidth that is "System Dependent," which is a critical weakness for a game like Fortnite that requires high bandwidth for texture streaming. The GPU’s FP32 performance is 6.144 TFLOPS, and its texture rate is 96.00 GTexel/s.

In the 3DMark Steel Nomad DX12 test, the Arc B370 scores 1,184, placing it in the 5th percentile of all GPUs. Its nearest rivals are older discrete parts, such as the ATI Radeon HD 5770 with a score of 1,190, and the ATI Mobility Radeon HD 5570 with a score of 1,186. This context is essential: the Arc B370 performs on par with graphics cards from over a decade ago. In Fortnite, this translates to the measured FPS results. The GPU’s low pixel rate of 48.00 GPixel/s is a primary constraint, as it directly limits how many pixels can be filled per second. At 4K resolution, the pixel count is over 8 million, and the GPU cannot keep up, resulting in the 13-35 FPS range observed. The GPU’s lack of dedicated VRAM is also a factor; the "System Shared" memory setup likely incurs latency penalties that are not present in dedicated solutions, further hurting performance in a fast-paced game.

Settings Recommendations

Based on the measured data, the optimal experience for this configuration is at 1920x1080 with Low settings, which yields an average FPS of 104. This is the only setting and resolution combination that approaches competitive playable frame rates. The jump from Low to Medium at 1080p costs 31 FPS (from 104 to 73), which is a significant drop that sacrifices smoothness for minor visual improvements. Given the GPU’s 5th percentile ranking, prioritizing frame rate is essential.

For users who can tolerate lower frame rates, 1440p Low offers an average of 66 FPS, which is playable but not ideal for fast-paced combat. The data shows that 1440p Medium drops to 46 FPS, which begins to feel sluggish. At 4K, no settings are recommended for active gameplay, as even Low settings only achieve 35 FPS. The Ultra preset is the worst choice, providing just 37 FPS at 1080p and 13 FPS at 4K, representing a 64% performance loss compared to Low at the same resolution. The measured rows clearly indicate that the Arc B370 does not have the raw throughput to support High or Ultra settings at any resolution without dropping below 60 FPS. Therefore, the best experience per the data is 1080p Low, which maximizes responsiveness and minimizes the GPU’s workload.
