# How This Combo Ranks

The AMD Ryzen 9 9900X paired with the Intel Arc B390 lands at rank 3289 out of 3700 tested combos in Fortnite. That places this configuration in the bottom 11% of all tested combinations, a striking result given the CPU's pedigree. The data suggests this pairing is heavily constrained by its graphics component, as the Ryzen 9 9900X alone sits in the 92nd percentile among all CPUs tested. The gap between the CPU's high percentile ranking and the combo's low overall rank tells a clear story: the Arc B390 is the limiting factor here. With an average benchmark score of just 1482 and a GPU percentile of 9, the Arc B390 ranks among the weakest graphics solutions in the database. The nearest GPU rivals — the NVIDIA GeForce GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — all score within 1.3% to 2.7% of the Arc B390, confirming this is entry-level territory. This combo's rank reflects that reality, and the measured Fortnite frame rates align perfectly with what the GPU's low percentile would predict.

GPU Role

The Intel Arc B390 operates as an integrated graphics processor (IGP) with a bus interface of "IGP" and a slot width of "IGP." Its memory configuration is "System Shared" across size, type, and bus width, with bandwidth listed as "System Dependent." This means the GPU borrows from the system's DDR5 memory rather than having dedicated VRAM, a design choice that directly impacts Fortnite performance. Base clock sits at 300 MHz, boosting up to 2500 MHz, with 1536 shading units, 48 texture mapping units, and 24 raster operation units. The chip, codenamed Panther Lake, uses Intel's Xe3-LPG architecture on a 3 nm process, and it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The pixel rate is 60.00 GPixel/s, texture rate is 120.0 GTexel/s, and FP32 performance reaches 7.680 TFLOPS, with FP16 at 15.36 TFLOPS (2:1). Despite these specifications, the GPU's 3DMark Steel Nomad DX12 score of 1482 places it at the 9th percentile, and its nearest rivals are all legacy NVIDIA parts from over a decade ago. In Fortnite, the impact is severe: at 1080p Ultra, the combo manages only 41 FPS average, while 4K Ultra drops to 14 FPS. The shared memory architecture means the GPU competes with the CPU for bandwidth, and the data shows the Arc B390 simply lacks the raw throughput needed for smooth gameplay at higher settings.

Resolution Scaling

The measured FPS data reveals how this combo scales across resolutions. At 1080p Low, the average is 115 FPS, which drops to 73 FPS at 1440p Low and 39 FPS at 4K Low. That represents a 36.5% reduction from 1080p to 1440p and a 46.6% further reduction from 1440p to 4K. For High settings, the progression is 63 FPS at 1080p, 40 FPS at 1440p, and 21 FPS at 4K — a 36.5% drop and then a 47.5% drop. Medium settings show 81 FPS at 1080p, 51 FPS at 1440p, and 27 FPS at 4K, with the 1080p to 1440p drop at 37.0% and 1440p to 4K at 47.1%. Ultra settings follow the same pattern: 41 FPS at 1080p, 26 FPS at 1440p, and 14 FPS at 4K, a 36.6% and 46.2% reduction respectively. The consistency of these percentage drops across all settings — hovering around 36-37% for the first step and 46-47% for the second — indicates a purely GPU-bound scenario. If the CPU were limiting, the scaling would flatten at lower resolutions, but the data shows no such plateau. The Arc B390's rendering pipeline is overwhelmed as pixel count increases, and the system-shared memory bandwidth becomes a bottleneck. At 1080p Low, the 115 FPS figure is the only playable result, and even that falls short of high-refresh expectations. The scaling pattern strongly suggests that upgrading the GPU would yield near-linear FPS improvements across all resolutions, while the CPU sits largely idle.

These deltas are minimal, showing the CPU is competitive with much higher-tier server and desktop parts.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution. At 1080p, Low settings provide the only truly smooth experience at 115 FPS average, which is ideal for competitive play. Medium settings at 1080p still offer 81 FPS, but the 69 FPS minimum suggests occasional dips below 70 FPS, which could be noticeable in fast-paced Battle Royale scenarios. High settings at 1080p drop to 63 FPS, which is playable but not ideal for a competitive title. Ultra at 1080p falls to 41 FPS, which is borderline for casual play but unsuitable for any serious engagement. At 1440p, only Low settings break the 60 FPS threshold at 73 FPS, making it the sole viable option at this resolution. Medium at 1440p delivers 51 FPS, which could work for slower-paced play but risks stutter in crowded fights. High and Ultra at 1440p are not recommended, with 40 FPS and 26 FPS respectively. At 4K, all settings fail to reach 40 FPS, with Low at 39 FPS being the only remotely playable option, and even that will feel sluggish. The data suggests the best experience is 1080p Low for competitive integrity, or 1080p Medium if visual quality is prioritized over maximum frame rate. The 81 FPS average at Medium with a 69 FPS floor provides a balance that most players would find acceptable, though the 115 FPS Low setting offers double the headroom above the 60 FPS baseline.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor from the 9000 series, built on Zen 5 architecture with a Granite Ridge codename. It uses a 4 nm process from TSMC with 16,630 million transistors across a 2x 70.6 mm² die size. Base clock is 4.40 GHz with a boost clock of 5.60 GHz, and it has a 120 W TDP. Cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. Memory support is DDR5 with dual-channel bandwidth of 89.6 GB/s, and ECC memory is supported. The CPU's benchmark results are impressive: Cinebench R23 multi-core scores 32172, single-core 2253; Geekbench multi-core 22174, single-core 3010; 3DMark max threads 13929, single thread 1286. Passmark scores include 54643 for multithread, 4672 for single thread, and 181056 for integer math. The CPU sits at the 92nd percentile among all CPUs, with an average score of 57498. Its nearest rivals are the AMD EPYC 9015 (57555, -0.1%), AMD EPYC 7313 (57399, +0.2%), Intel Core i9-14900 (58115, -1.1%), and Intel Xeon Platinum 8260M (58323, -1.4%). In Fortnite, this CPU's capabilities are largely untapped. The measured FPS at 1080p Low (115 FPS) is the highest result, and even that is modest given the CPU's single-thread score of 4672 in Passmark. The data implies that Fortnite's engine is not stressing the CPU, as evidenced by the resolution scaling pattern — if the CPU were a constraint, FPS would not drop so consistently with resolution increases. The Ryzen 9 9900X could clearly drive far higher frame rates with a more capable GPU, and its 24 threads provide ample headroom for background tasks, streaming, or content creation while gaming. The CPU's release date of August 2024 and launch MSRP of $499 position it as a high-end desktop part, but in this pairing, its potential is wasted on the Arc B390's limited throughput.

Measured FPS Breakdown

At 1920x1080, the combo achieves 115 FPS average on Low settings, 81 FPS on Medium (with a range of 69 to 93 FPS), 63 FPS on High, and 41 FPS on Ultra. These figures show a clear degradation as settings increase, with Ultra delivering less than half the frame rate of Low. The Medium range of 69-93 FPS indicates stability, with the minimum staying above 60 FPS. At 2560x1440, Low settings produce 73 FPS, Medium produces 51 FPS (range 44 to 59 FPS), High produces 40 FPS, and Ultra produces 26 FPS. The Medium range at 1440p shows the minimum dipping to 44 FPS, which would be noticeable in combat. At 3840x2160, Low settings yield 39 FPS, Medium yields 27 FPS (range 23 to 31 FPS), High yields 21 FPS, and Ultra yields 14 FPS. None of the 4K results reach 40 FPS, making the resolution impractical for this combo. The data shows that the gap between Low and Ultra widens with resolution: 74 FPS difference at 1080p (115 vs 41), 47 FPS at 1440p (73 vs 26), and 25 FPS at 4K (39 vs 14). This pattern indicates that the GPU's limitations are amplified at higher resolutions, where the rendering load increases exponentially. The Medium setting's min/max data is the only complete range set, and it shows consistent behavior: the spread between min and max is 24 FPS at 1080p, 15 FPS at 1440p, and 8 FPS at 4K, suggesting the GPU's frame pacing becomes more consistent at lower resolutions where it isn't as heavily loaded. Overall, the measured FPS paints a picture of a combo that can handle Fortnite at 1080p with reduced settings, but struggles at higher resolutions or quality presets. The combination of a top-tier CPU and an entry-level GPU results in a system that is fundamentally GPU-limited, and the data suggests that any meaningful improvement in Fortnite performance would require a more powerful graphics solution.
