Valorant

This combo, the AMD Ryzen 5 5600X paired with the Intel Arc B390, lands near the bottom of the performance hierarchy for Valorant. With a rank of 2534 out of 2883 tested combinations, it sits in the 12th percentile of all combos, meaning roughly 88% of tested systems deliver higher frame rates. The data indicates this is not a combination built for competitive play at high refresh rates, as the GPU becomes a significant bottleneck even though the CPU is a capable performer.

How This Combo Ranks

The combo rank of 2534 out of 2883 places this pairing firmly in the lower quartile of tested systems for Valorant. This is a striking result because the Ryzen 5 5600X is a strong processor, holding the 75th percentile among all CPUs in the database. The discrepancy between the CPU's solid standing and the combo's poor rank points directly to the Intel Arc B390 as the limiting factor.

Benchmark results for the GPU show it sits in the 9th percentile among all GPUs, with an average benchmark score of 1482. Its nearest rivals in the GPU database are the NVIDIA GeForce GT 520MX, GeForce 800M, GeForce GT 625 OEM, and GeForce GT 710, with score deltas of 1.3%, 1.5%, 2.5%, and 2.7% respectively. These are all entry-level or legacy parts, which contextualizes the Arc B390's performance class.

The CPU, in contrast, shows a different story. Its average benchmark score is 21771, placing it within 0.6% of rivals like the AMD Ryzen 7 4800H, Ryzen 5 PRO 6650U, Intel Core i7-11700, and AMD EPYC 9554P. The delta percentages are tight, ranging from +0.1% to -0.6%, showing the 5600X is right in line with these other mid-range and high-end parts. This contrast between a mid-tier CPU and a bottom-tier GPU explains the overall combo ranking: the system is held back by the graphics solution.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel's 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 render output units, along with 12 ray tracing cores. The GPU clock operates with a base of 300 MHz and a boost of 2500 MHz, which gives it a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. Its FP32 performance is rated at 7.680 TFLOPS.

The memory situation is critical for this game. The Arc B390 uses System Shared memory, meaning it has no dedicated VRAM and instead draws from the system's main memory. The memory bus width is also System Shared, and the bandwidth is listed as System Dependent. This architecture has a direct impact on Valorant performance, as the game's frame rendering depends heavily on memory throughput. The shared memory design means the GPU competes with the CPU for memory access, which can create latency and bandwidth bottlenecks.

In terms of API support, the GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Valorant runs on a custom engine that is generally not demanding on GPU features, but the raw throughput of the Arc B390 is simply too low to push high frame rates. The 3DMark Steel Nomad DX12 score of 1482 confirms this, as it places the GPU in the 9th percentile overall. The 80 W TDP and IGP form factor mean this is not a discrete solution, so thermal and power constraints are less relevant than the fundamental compute limits.

Resolution Scaling

The measured FPS data shows clear scaling patterns as resolution increases from 1080p to 4K. At 1080p with Low settings, the combo produces 331 FPS average. Moving to 1440p Low drops that to 282 FPS, a 14.8% decrease. At 4K Low, the average falls to 225 FPS, which is a further 20.2% drop from 1440p and a 32.0% drop from 1080p. This scaling behavior indicates that the GPU is the limiting component, as frame rates are highly sensitive to resolution changes.

The pattern holds across other settings levels. At Medium settings, 1080p yields 218 FPS, 1440p yields 186 FPS (14.7% lower), and 4K yields 149 FPS (31.7% lower than 1080p). High settings show similar relative drops: 207 FPS at 1080p, 177 FPS at 1440p (14.5% lower), and 141 FPS at 4K (31.9% lower). The consistency of these percentage drops across settings levels suggests a GPU-bound scenario where the rendering load scales predictably with pixel count.

The resolution scaling analysis points to the GPU as the primary bottleneck. If the CPU were the limiting factor, frame rates would stay relatively flat across resolutions, since the CPU workload per frame doesn't change with resolution. Instead, the data shows significant FPS drops when moving to higher resolutions, which is characteristic of a graphics-bound system. The Ryzen 5 5600X has the compute headroom to handle the game's logic at these frame rates, but the Arc B390 cannot keep up with the increased pixel throughput demands.

Measured FPS Breakdown

At 1920x1080, the lowest resolution tested, the combo achieves its best results. Low settings produce an average of 331 FPS, which is the highest measured frame rate in the entire dataset. Medium settings average 218 FPS with a minimum of 185 FPS and maximum of 250 FPS. High settings average 207 FPS, and Ultra settings average 198 FPS. The spread between Low and Ultra at 1080p is 133 FPS, showing that the GPU has performance headroom when the visual load is reduced.

Moving to 2560x1440, the frame rates drop noticeably. Low settings average 282 FPS, a 49 FPS decrease from 1080p Low. Medium settings average 186 FPS with a range of 158 to 214 FPS. High settings average 177 FPS, and Ultra settings average 169 FPS. The difference between Low and Ultra at 1440p is 113 FPS, a slightly smaller spread than at 1080p, suggesting the GPU is starting to become more saturated.

At 3840x2160, the highest resolution tested, the performance drops further. Low settings average 225 FPS, Medium averages 149 FPS with a range of 126 to 171 FPS, High averages 141 FPS, and Ultra averages 135 FPS. The Low-to-Ultra spread at 4K is 90 FPS, indicating that the GPU is heavily loaded even at Low settings. The minimum FPS at 4K Medium is 126 FPS, which is still playable but far from the high refresh rates competitive players might target.

The data reveals that the Arc B390 is capable of producing playable frame rates at all tested resolutions, but the margin for error is thin. At 1080p Low, the 331 FPS average is competitive for esports. However, even at 1080p Ultra, the average drops to 198 FPS, and at 4K Ultra, it falls to 135 FPS. The frame time consistency, where available from the Medium settings data, shows the minimum FPS is roughly 15% below the average across all resolutions, which is acceptable but not exceptional.

CPU Role

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer, built on TSMC's 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.60 GHz, with a 65 W TDP. The CPU supports DDR4 memory with dual-channel configuration and a bandwidth of 51.2 GB/s. It uses the AMD Socket AM4 interface and supports PCIe Gen 4 with 20 lanes from the CPU.

The CPU's benchmark results show strong single-threaded and multi-threaded performance. In Cinebench R23, it scores 1541 in single-core and 11838 in multi-core. Geekbench results show 1989 single-core and 9173 multi-core. The 3DMark tests show scaling from 1793 with 2 threads to 5588 with max threads, which is a 3.1x improvement from 2 to 16 threads. This indicates the CPU can leverage additional threads effectively, though Valorant typically relies on fewer cores.

The 5600X has 32 MB of L3 cache, which is beneficial for game performance. The cache hierarchy includes 64 KB L1 per core and 512 KB L2 per core. The CPU's percentile rank of 75 among all CPUs, with an average benchmark score of 21771, places it above the majority of processors in the database. Its nearest rivals include the Ryzen 7 4800H, Ryzen 5 PRO 6650U, Core i7-11700, and EPYC 9554P, all within a narrow band of 0.6% performance delta.

In Valorant, the CPU's role is to handle game logic, physics, and frame pacing. The 5600X has ample single-thread performance for this task, as evidenced by its 917 single-thread score in 3DMark and 3364 in PassMark single-thread tests. The CPU's 12 threads provide headroom for background tasks and streaming. However, the measured FPS data suggests the CPU is not the constraint, as frame rates scale heavily with resolution, which is a GPU characteristic.

The mismatch between CPU and GPU performance classes is stark. The CPU holds the 75th percentile, while the GPU holds the 9th percentile. This means the 5600X is likely waiting on the Arc B390 to finish rendering frames, leaving CPU performance on the table. In a system with a more capable GPU, the 5600X could likely sustain higher frame rates than what this combo achieves, but the current pairing caps the system's potential.
