Valorant

Valorant, when paired with the AMD Ryzen 9 7900X and Intel Arc B390, presents a unique performance profile defined by a stark contrast between a high-end CPU and a low-end integrated GPU. The benchmark results indicate that this combination is overwhelmingly limited by the graphics subsystem, with the CPU’s substantial processing power remaining largely underutilized in this esports title. The data shows a system capable of high frame rates at lower resolutions, but one that struggles to maintain those levels as graphical load increases, revealing a bottleneck that is entirely GPU-bound.

Resolution Scaling

The measured FPS data reveals a clear and predictable trend: performance degrades significantly as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 207 FPS at 1080p to 177 FPS at 1440p, a decline of 30 FPS. Moving further up to 4K, the average falls to 141 FPS, representing a 66 FPS drop from the 1080p baseline. This pattern is consistent across all settings presets, indicating that the Intel Arc B390's rendering pipeline is the primary constraint.

The scaling behavior points directly to the GPU as the limiting component. The percentage drop from 1080p to 4K is substantial across the board, with the Low preset showing the largest absolute decline from 331 FPS to 225 FPS. This steep curve is characteristic of a GPU that is being saturated by pixel fill rate and memory bandwidth demands. The Ryzen 9 7900X, with its 12 cores and 24 threads, is not the constraint here; if it were, the frame rate would remain relatively flat across resolutions, as the CPU's workload is largely independent of resolution. Instead, the data shows a classic GPU-bound scenario where the Arc B390's limited 7.680 TFLOPS of FP32 compute and system-shared memory become the determining factors.

The gap between the Low and Ultra presets also widens with resolution. At 1080p, the difference between Low (331 FPS) and Ultra (198 FPS) is 133 FPS. At 4K, this gap narrows to 90 FPS (225 FPS vs 135 FPS). This suggests that at lower resolutions, the CPU can feed frames fast enough to expose the GPU's raw shader limitations, but at higher resolutions, the GPU's memory and fill-rate constraints become so dominant that the additional work from higher settings has a relatively smaller impact on the already reduced frame rate. The system is fundamentally bound by the Arc B390's capabilities.

Settings Recommendations

According to the measured rows, the optimal balance between visual fidelity and frame rate is achieved at the Medium preset. This setting provides a meaningful performance uplift over High and Ultra while maintaining a playable frame rate at all tested resolutions. At 1080p, Medium delivers 218 FPS, which is 11 FPS higher than High and 20 FPS higher than Ultra. At 1440p, the Medium preset yields 186 FPS, outperforming High by 9 FPS and Ultra by 17 FPS. Even at 4K, Medium holds at 149 FPS, which is 8 FPS above High and 14 FPS above Ultra.

The Low preset offers the highest raw frame rates, with a staggering 331 FPS at 1080p and 282 FPS at 1440p. However, this comes at the cost of visual quality. For competitive play where maximum frame rate is paramount, Low is the clear choice, but the data suggests that Medium provides a significant upgrade in visual settings for a relatively modest performance penalty. The step from Low to Medium costs 113 FPS at 1080p (331 to 218), but the step from Medium to High only costs 11 FPS (218 to 207). This indicates that Medium is the sweet spot, capturing much of the visual improvement from higher presets while avoiding the steep performance cliff found when transitioning from Low. The Medium preset also shows the only recorded minimum and maximum FPS values, with a range from 185 to 250 FPS at 1080p, indicating a stable frame time delivery that is suitable for consistent gameplay.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, manufactured on Intel's 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. Its memory is designated as "System Shared," meaning it relies on the host system's DDR5 RAM, with bandwidth described as "System Dependent." This architecture is fundamentally different from a discrete GPU, and the benchmark results reflect its limitations in a demanding FPS title like Valorant.

The GPU's performance percentile is telling: it ranks in the 9th percentile against all GPUs in the database. Its nearest rivals according to the average benchmark score are the NVIDIA GeForce GT 520MX, GeForce 800M, GT 625 OEM, and GT 710, with delta percentages of 1.3%, 1.5%, 2.5%, and 2.7% respectively. This places the Arc B390 in the company of very old, entry-level discrete parts, which are not designed for modern gaming at high settings. The 3DMark Steel Nomad DX12 score of 1482 confirms this low-end positioning. In Valorant, this translates to frame rates that are high enough for casual play at lower settings, but the GPU's 24 ROPs and 48 TMUs are clearly overwhelmed by the pixel and texture processing demands at higher resolutions and presets.

The system-shared memory is a critical factor. With no dedicated VRAM, the GPU must compete with the CPU for memory bandwidth. This is a likely cause of the significant frame rate drops at 4K, where memory bandwidth demands increase exponentially. The GPU's 7.680 TFLOPS of FP32 compute is also a limiting factor, as the shader complexity of higher presets directly impacts performance. In essence, the Arc B390 is a capable integrated solution for basic tasks, but its performance in Valorant is severely constrained by its memory architecture and compute throughput.

How This Combo Ranks

In the database of tested combinations for Valorant, the AMD Ryzen 9 7900X and Intel Arc B390 combination ranks 2534 out of 2883 total combos. This places it in the bottom 12% of all tested systems, a position that reflects the GPU's low performance ceiling. This ranking is a direct consequence of the Arc B390's 9th percentile standing among GPUs, despite the CPU's impressive 91st percentile ranking among all CPUs.

The data shows a significant mismatch in tier between the two components. The Ryzen 9 7900X is a high-end desktop processor, while the Arc B390 is an integrated graphics solution found in mobile or low-power platforms. The combo rank of 2534 indicates that the system is heavily held back by the GPU, and its overall performance in Valorant is more representative of the GPU's capabilities than the CPU's. For reference, a system with this CPU paired with a discrete mid-range GPU would likely rank significantly higher, but the data only shows this specific pairing. The low rank serves as a quantitative measure of the bottleneck, confirming that the Arc B390 is the defining factor in this system's gaming performance.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture (codenamed Raphael). It features a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with a substantial 64 MB of shared L3 cache. Its benchmark scores are impressive, with a Cinebench R23 multicore score of 29,300 and a single-core score of 2016.5. This processing power is more than sufficient for Valorant, which is a game that typically relies heavily on single-core performance for game logic and physics.

Given the GPU bottleneck, the CPU's role in this system is to ensure that frame delivery is not a limiting factor. The data indicates that the CPU is not the bottleneck, as frame rates vary significantly based on GPU load. If the CPU were the constraint, the frame rates would be more consistent across different resolutions. The Ryzen 9 7900X's high single-thread performance, evidenced by its 3DMark single-thread score of 1093 and Passmark single-thread score of 4238, ensures that it can process game instructions far faster than the Arc B390 can render frames. This is a classic case where the CPU's potential is left on the table.

The CPU's 91st percentile ranking against all CPUs, with nearest rivals including the AMD EPYC 7313P and Intel Core i7-14700F, reinforces its high-end status. However, in this specific pairing, its performance is capped by the GPU. The 12 cores and 24 threads are largely irrelevant for Valorant's workload, as the game's engine is not designed to utilize such a high core count. The system's performance is entirely dictated by the GPU's rendering speed, meaning the CPU's advanced architecture and high clock speeds have no bearing on the final frame rate output.
