Q: Does the GPU have dedicated VRAM?

A: No, the Intel Arc B370 uses System Shared memory for both capacity and bandwidth, with bandwidth described as "System Dependent" — meaning game performance will vary based on the host system's memory configuration.

GPU Role

The Intel Arc B370 is the dominant bottleneck in this configuration, and its specifications explain why. This is an integrated graphics processor (IGP) based on the Panther Lake chip with Xe3-LPG architecture, built on Intel's 3nm process. It operates with a 300 MHz base clock and 2400 MHz boost clock, but critically, it shares system memory rather than having dedicated VRAM. The memory bus width is "System Shared," and bandwidth is "System Dependent," meaning the GPU's ability to feed its 1280 shading units, 40 texture mapping units, and 20 raster output pipelines depends entirely on the host system's DDR4 memory configuration.

The GPU's raw compute figures tell a modest story: 6.144 TFLOPS FP32 performance and 48.00 GPixel/s pixel rate. With only 10 ray tracing cores and no tensor cores listed, this is not a hardware-accelerated ray tracing powerhouse. The 3DMark Steel Nomad DX12 score of 1184 places this GPU at the 5th percentile, and its nearest rivals are all legacy AMD/ATI parts from over a decade ago — the ATI Mobility Radeon HD 5570 (1186) and ATI Radeon HD 5770 (1190). This contextualizes the Fortnite results: this GPU is competing with ancient discrete graphics hardware despite being a modern integrated solution.

The 25W TDP and IGP slot width confirm this is designed for power efficiency, not gaming performance. The GPU's impact on Fortnite is evident in the measured FPS: at 1080p Low, the system manages 104 FPS, but this drops precipitously as settings increase. The GPU's shared memory architecture likely compounds the problem in Fortnite, which benefits from dedicated VRAM for texture streaming and geometry processing.

Resolution Scaling

The FPS degradation from 1080p to 4K reveals a GPU that struggles as pixel count increases. At Low settings, the progression is stark: 104 FPS at 1920x1080 drops to 66 FPS at 2560x1440 (a 36.5% reduction) and then to 35 FPS at 3840x2160 (a 66.3% reduction from 1080p). This scaling pattern suggests the GPU's fill rate and memory bandwidth are severely taxed at higher resolutions.

At Medium settings, the same trend continues: 73 FPS at 1080p, 46 FPS at 1440p, and 25 FPS at 4K. The 1440p result shows a 37% drop from 1080p, while 4K shows a 65.8% drop. High settings produce 57 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K — the 4K result being only 33.3% of the 1080p performance. Ultra settings are the most punishing: 37 FPS at 1080p, 24 FPS at 1440p, and 13 FPS at 4K.

The resolution scaling indicates a purely GPU-limited scenario. If the CPU were the bottleneck, we would expect FPS to remain relatively flat across resolutions, but the dramatic drops suggest the Arc B370's rendering capabilities are exhausted quickly. The 4K Medium result (25 FPS) with min FPS of 21 and max of 28 shows tight frame pacing, indicating consistent GPU saturation rather than intermittent CPU stalls. The 1440p Medium measurement (46 FPS average, 39 min, 53 max) similarly shows a narrow range, further confirming GPU-bound operation.

Settings Recommendations

Based on the measured data, the only viable settings for a playable Fortnite experience are at 1920x1080 with Low settings, which produces 104 FPS average. This is the sole configuration that achieves triple-digit frame rates. Medium settings at 1080p deliver 73 FPS, which is acceptable for casual play but below competitive thresholds. High settings at 1080p (57 FPS) and Ultra settings at 1080p (37 FPS) are progressively less suitable.

At 2560x1440, Low settings produce 66 FPS, which could be considered playable but marginal. Medium at 1440p yields 46 FPS, and High drops to 36 FPS. Ultra at 1440p (24 FPS) is not recommended. At 3840x2160, even Low settings (35 FPS) fail to reach smooth playability, and the Ultra preset at 4K (13 FPS) is essentially a slideshow.

The data suggests that for Fortnite's competitive Battle Royale mode, players should prioritize frame rate over visual fidelity. The 1080p Low setting at 104 FPS is the only configuration that approaches competitive refresh rates. The Medium preset at 1080p (73 FPS) offers a balance of visual quality and responsiveness, with a min FPS of 62 that keeps frame times relatively consistent. Given that the Ultra preset at any resolution fails to exceed 37 FPS, there is no scenario where maximum settings provide an acceptable experience with this combo.

Measured FPS Breakdown

1920x1080: The Low preset delivers 104 FPS average, making it the only setting that clears the 100 FPS threshold. Medium produces 73 FPS with a measured range of 62-84 FPS, showing consistent performance. High settings yield 57 FPS, while Ultra drops to 37 FPS. The gap between Low and Medium (31 FPS) is larger than the gap between Medium and High (16 FPS), suggesting diminishing returns on visual quality versus performance cost.

2560x1440: Low settings achieve 66 FPS, a 36.5% reduction from the 1080p Low result. Medium delivers 46 FPS with a range of 39-53 FPS, maintaining relatively stable frame pacing. High produces 36 FPS, and Ultra falls to 24 FPS. At this resolution, the 1440p Medium result (46 FPS) is barely half of the 1080p Low result, illustrating how resolution scaling taxes the GPU.

3840x2160: Low settings produce 35 FPS, which is 33.7% of the 1080p Low performance. Medium delivers 25 FPS with a tight range of 21-28 FPS, showing consistent but unplayable performance. High yields 19 FPS, and Ultra plummets to 13 FPS. None of these 4K results approach playability, and the 4K Medium frame range (21-28) indicates the GPU is operating at its absolute limits.

The complete dataset shows no min/max values for most settings — only Medium presets at each resolution include min/max columns. This suggests the measurement methodology focused on average FPS for the other presets, but the Medium preset data provides insight into frame consistency. Across all resolutions, the Medium preset shows a spread of roughly 15-20% between min and max FPS, indicating relatively stable GPU utilization without major spikes or drops.

CPU Role

The AMD Ryzen 7 3700X is a Zen 2 (Matisse) architecture processor with 8 cores and 16 threads, base clock of 3.60 GHz and boost clock of 4.40 GHz. It features 32 MB of L3 cache, 512 KB L2 per core, and 64 KB L1 per core. Built on TSMC's 7nm process with 3,800 million transistors on a 74 mm² die, this 65W TDP processor supports DDR4 memory with dual-channel configuration and 51.2 GB/s memory bandwidth. It uses the AMD Socket AM4 with PCIe Gen 4 (24 lanes CPU only), and its launch MSRP was $329.

The CPU's benchmark results show a well-rounded performer: PassMark multithread score of 22458, single-thread score of 2656, and a physics score of 1181. Cinebench R15 results show 2092 multicore and 204 singlecore. Geekbench scores are 8899 multicore and 1593 singlecore. The average benchmark score of 34260 places this CPU at the 84th percentile among all CPUs, with nearest rivals being the AMD Ryzen AI 7 350 (34222, 0.1% slower), AMD EPYC 4244P (34220, 0.1% slower), Intel Core i5-13450HX (34333, 0.2% faster), and Intel Core Ultra 7 165H (34083, 0.5% slower). These near-identical scores indicate the 3700X remains competitive with much newer processors in synthetic benchmarks.

In Fortnite specifically, the CPU's role is secondary to the GPU bottleneck. At 1080p Low (104 FPS), the CPU likely has headroom, as the GPU is the limiting factor. However, the CPU's 8-core/16-thread configuration and 4.40 GHz boost clock provide sufficient single-thread performance for Fortnite's game logic and physics. The CPU's 84th percentile ranking suggests it could support higher frame rates with a more powerful GPU, but in this combo, the Arc B370's 5th percentile GPU ranking caps performance well below what the CPU could theoretically deliver.

How This Combo Ranks

The combo ranks 2517th out of 2740 tested combinations in Fortnite, placing it in the bottom 8.2% of all tested systems. This low ranking is directly attributable to the GPU's performance class — the Arc B370's 5th percentile GPU standing and its nearest rivals being decade-old ATI/AMD parts (ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, AMD FirePro M2000) place this combo in the same performance tier as legacy integrated graphics.

The CPU's 84th percentile ranking creates a significant asymmetry: the Ryzen 7 3700X is a capable processor that benchmarks within 0.5% of modern chips like the Intel Core Ultra 7 165H, yet the combo's overall game ranking is dragged down by the GPU. This suggests that in Fortnite, the GPU is the sole determinant of this combo's competitive standing. If paired with a more powerful discrete GPU, the Ryzen 7 3700X could likely push far higher in the rankings, but with the Arc B370, the system is confined to the bottom decile.

The ranking also implies that Fortnite's performance scaling heavily favors GPU capability. The game's Battle Royale genre requires sustained high frame rates for competitive play, and the Arc B370's inability to maintain 60+ FPS at 1080p Medium (73 FPS at Low, 57 FPS at High) limits this combo to low-settings play. The 2517th rank out of 2740 combos places this system in the company of low-end laptops and ancient desktop GPUs, despite the modern CPU. For users considering this combination, the data clearly indicates that the GPU is the constraining factor, and any upgrade path should focus on replacing or supplementing the Arc B370 with a more capable graphics solution.
