Fortnite

Fortnite on the Intel Core i7-12700KF paired with the Intel Arc B370 presents a stark illustration of GPU-bound performance. The data places this combination at rank 2517 out of 2740 tested combos, placing it in the bottom 8% of all tested configurations. The Intel Core i7-12700KF is a high-end desktop processor, but the Arc B370, an integrated GPU with a 5th percentile ranking against all other GPUs, severely limits the experience. Benchmark results indicate a system that can handle the game’s logic easily but struggles to render frames at acceptable rates, making the GPU the definitive bottleneck in every scenario.

Resolution Scaling

The measured FPS data reveals a predictable but severe decline in performance as resolution increases, confirming that the Intel Arc B370 is the primary limiting component. At 1080p with Low settings, the system achieves an average of 104 FPS. Moving to 1440p at the same settings drops the average to 66 FPS, a 36.5% reduction. Pushing further to 4K at Low settings yields an average of just 35 FPS, which is a 66.3% drop from the 1080p result. This scaling pattern is typical of a GPU that is running out of pixel processing power; the load on the integrated graphics increases quadratically with resolution, and the Arc B370’s limited pixel rate of 48.00 GPixel/s is quickly overwhelmed.

The trend holds across all settings presets. With High settings, the frame rate falls from 57 FPS at 1080p to 36 FPS at 1440p (a 36.8% decrease), and finally to 19 FPS at 4K (a 66.7% decrease from 1080p). The Medium preset shows a similar trajectory: 73 FPS at 1080p, 46 FPS at 1440p, and 25 FPS at 4K. The Ultra preset, which is the most demanding, starts at a lowly 37 FPS at 1080p and plummets to 24 FPS at 1440p and 13 FPS at 4K. The consistency of these percentage drops across different settings strongly suggests that the system is not CPU-limited at any point; if the CPU were the bottleneck, we would expect to see a smaller difference between resolutions at lower settings where the CPU has to do relatively more work. Instead, the frame rate scales almost inversely with the number of pixels, which is the signature of a GPU that is saturated.

The jump from 1080p to 1440p is particularly punishing, with the system losing roughly a third of its performance. The jump from 1440p to 4K is even more brutal, often halving the already low frame rates. For example, at Medium settings, the 1440p average of 46 FPS drops to 25 FPS at 4K. This shows that the Arc B370 has a very narrow window of playable performance, and it is only found at the lowest resolution and settings. The data suggests that any attempt to play at 1440p or above will result in a sub-30 FPS experience for all but the absolute lowest settings, making the game feel sluggish and unresponsive. The 4K resolution is effectively unplayable for this configuration, with the highest average FPS being just 35 on Low settings, which still represents a significant compromise in visual fidelity.

GPU Role

The Intel Arc B370 is the decisive factor in this system’s Fortnite performance. As an integrated GPU (IGP) with a 25 W TDP, it is designed for basic display output and light workloads, not for competitive gaming. Its benchmark score in 3DMark Steel Nomad DX12 is 1184, placing it in the 5th percentile of all GPUs. This places it in the company of legacy parts like the ATI Mobility Radeon HD 5570 (which scores 1186, a 0.2% difference) and the AMD Radeon HD 7650M (which scores 1192, a 0.7% difference). The data clearly shows that the Arc B370 is not in the same performance class as even entry-level discrete graphics cards from over a decade ago.

The GPU’s specifications support this conclusion. It features 1280 shading units, 40 texture mapping units, and 20 render output units, figures that are dwarfed by modern discrete GPUs. Its boost clock is rated at 2400 MHz, but this is not enough to compensate for the low core counts. The memory situation is even more constraining. The Arc B370 uses "System Shared" memory, meaning it relies on the system’s main RAM rather than dedicated VRAM. Its bandwidth is listed as "System Dependent," which means it is limited by the memory controller and the speed of the installed DRAM. For a game like Fortnite, which can be sensitive to memory bandwidth, this is a significant handicap.

The low ROP count of 20 is particularly problematic for high resolutions. ROPs are responsible for pixel output, and having only 20 of them explains the dramatic frame rate drops seen when moving from 1080p to 1440p and 4K. The GPU simply cannot fill the framebuffer fast enough. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are theoretical maximums that are far below what is needed for smooth gameplay at high detail settings. The GPU’s DirectX 12 Ultimate (12_2) support is a positive feature, but it doesn't translate into performance. The 3DMark Steel Nomad score of 1184 is the only GPU benchmark available, and it confirms that this is a very weak graphics solution. The system’s ranking of 2517 out of 2740 combos is a direct consequence of this GPU’s limitations.

Settings Recommendations

Given the measured data, the only way to achieve a playable frame rate with the Intel Arc B370 is to make significant compromises. The 1080p Low preset, with an average of 104 FPS, is the only configuration that can be considered smooth. This is the clear recommendation for any user who prioritizes a responsive experience. The 1080p Medium preset, which averages 73 FPS, is also viable and offers a better visual experience, but it comes at the cost of 30% fewer frames per second compared to Low.

The 1080p High preset, at 57 FPS, is marginal. It is playable but may feel inconsistent in fast-paced combat scenarios where frame drops are most noticeable. The 1440p Low preset, at 66 FPS, is an interesting alternative, offering a higher resolution at a slightly lower frame rate than 1080p High. However, the 1080p Medium preset provides a better balance of visual quality and performance than 1440p Low, as the higher resolution cannot compensate for the lower detail settings in this case. The Ultra preset is not recommended at any resolution. At 1080p, it only manages an average of 37 FPS, which is too low for a competitive game. At 1440p and 4K, the Ultra preset produces averages of 24 FPS and 13 FPS, respectively, making the game unplayable.

The data suggests that the "Medium" preset at 1080p is the sweet spot for visual quality, as it provides a 28% improvement in frame rate over High while still looking significantly better than Low. For players who demand the highest possible frame rate, the Low preset is the only option. The 1440p resolution should be avoided unless the player is willing to use Low settings and tolerate an average of 66 FPS. The 4K resolution is effectively a non-starter, with no preset achieving an average above 35 FPS. In short, the Arc B370 forces the user to play at 1080p, and the choice is between a smooth but ugly experience (Low) or a less smooth but prettier experience (Medium).

CPU Role

The Intel Core i7-12700KF is a powerful desktop processor that is not the limiting factor in this configuration. It belongs to the Core 12th Gen series (Alder Lake-S architecture) and features 12 cores and 20 threads, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its benchmark scores are robust, including a Cinebench R23 multicore score of 28838 and a single-core score of 4071. It ranks in the 85th percentile of all CPUs, with an average benchmark score of 35365. This places it in a tie with the Intel Core i5-13600T (which scores 35305, a 0.2% difference) and the Intel Core i7-12700K (which scores 35287, a 0.2% difference). It is slightly ahead of the Intel Core i7-13700T (which scores 35403, a -0.1% difference).

Given this processing power, the CPU is more than capable of handling Fortnite's game logic, physics, and draw calls. The fact that the system’s overall rank is 2517 out of 2740 combos is almost entirely due to the GPU. If the CPU were the bottleneck, we would expect to see lower frame rates at 1080p Low settings, where the GPU has less work to do per frame. Instead, the 1080p Low result of 104 FPS is the highest of any configuration, showing that the CPU can feed frames to the GPU quickly. The 3DMark multi-threaded scores, such as 9983 for max threads and 9282 for 16 threads, confirm that the CPU's multi-core performance is not a concern for this title.

The CPU's 25 MB of shared L3 cache and support for DDR4 and DDR5 memory are also beneficial, though the GPU's "System Shared" memory means it will be competing with the CPU for memory bandwidth. The data suggests that the i7-12700KF has ample headroom, and the performance ceiling of this system is defined entirely by the Intel Arc B370. The CPU is ready for a much more powerful discrete GPU, and the current configuration represents a severe imbalance, where a top-tier processor is paired with a bottom-tier graphics solution. The 3DMark single-thread score of 1043 and Cinebench R20 single-core score of 1709 indicate that even single-threaded performance, which can be important for game engines, is strong. The weak link is unequivocally the GPU.
