Valorant

The AMD Ryzen 5 4600G paired with the Intel Arc B370 delivers a playable Valorant experience, but the data reveals a configuration that is heavily constrained by its integrated graphics solution. While the CPU provides ample processing power, the Arc B370's performance profile places this combo in the bottom tier of tested configurations, resulting in frame rates that are more than adequate for casual play yet far from competitive extremes.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly identifies the Intel Arc B370 as the primary limiting component in this system. At 1920x1080 with Low settings, the combo achieves an average of 299 FPS. Dropping the resolution to 2560x1440 at Low settings yields 255 FPS, and at 3840x2160 at Low settings, the average falls to 204 FPS. This progression shows a 31.8% reduction in frame rate from 1080p to 4K at Low settings, indicating that even at the lowest graphical preset, the GPU is struggling to keep pace with the resolution increase.

The scaling pattern becomes more pronounced when examining higher settings. At Medium settings, the average FPS drops from 197 at 1080p to 168 at 1440p, then to 134 at 4K. This represents a 32% decrease from 1080p to 4K, nearly identical to the Low settings scaling. The consistency of this percentage drop across settings suggests that the GPU's fill rate and pixel processing capabilities are the bottleneck. At High settings, the averages are 187 FPS at 1080p, 160 FPS at 1440p, and 128 FPS at 4K, again showing a similar 31.6% decline from the lowest to highest resolution.

The Ultra settings data reinforces this conclusion, with the combo producing 178 FPS at 1080p, 152 FPS at 1440p, and 122 FPS at 4K. The fact that the resolution scaling penalty remains relatively constant regardless of graphical settings is a strong indicator that the Arc B370's raw throughput, not its shading or texture capabilities, is the limiting factor. A CPU-bound scenario would typically show a much smaller FPS penalty at 4K, often as low as 10-15%, because the CPU would struggle to feed frames at any resolution equally. The consistent 30%+ penalty here points squarely at the GPU's memory bandwidth and pixel fill rate constraints, especially given that the GPU uses System Shared memory with system-dependent bandwidth.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Valorant, this pairing sits near the bottom. The combo holds a rank of 2645 out of 2883 tested combinations, placing it in the bottom 8.3% of all configurations. This ranking is primarily dragged down by the GPU's low benchmark scores. The Intel Arc B370 has a percentile rank of 5 among all GPUs, meaning it outperforms only 5% of the graphics cards in the database. Its average benchmark score of 1184 is nearly identical to that of the ATI Mobility Radeon HD 5570, which scores 1186, and the ATI Radeon HD 5770, which scores 1190.

The CPU, by contrast, is a relatively strong performer. The AMD Ryzen 5 4600G holds a percentile rank of 71 among all CPUs, placing it in the upper third of processors. Its average benchmark score of 17507 is closely matched with rivals such as the AMD Ryzen 3 PRO 5355GE at 17482, which is 0.1% behind, and the Intel Core 7 150U at 17395, which is 0.6% behind. The 4600G actually scores slightly higher than the Intel Core i3-14100T, which averages 17648, putting the 4600G 0.8% behind that chip. This CPU strength is wasted in this configuration because the GPU cannot translate the CPU's processing power into high frame rates at higher resolutions or settings.

The combination of a top-tier CPU and a bottom-tier GPU creates a severe imbalance. In Valorant, a game that is typically CPU-bound at lower resolutions, the GPU bottleneck becomes the dominant factor at 1440p and 4K. The rank of 2645 out of 2883 reflects this mismatch, showing that while the CPU could handle far more demanding graphics hardware, the Arc B370 limits the overall system to entry-level performance. This ranking suggests that users seeking competitive frame rates above 300 FPS would need to pair this CPU with a significantly more powerful discrete GPU.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings levels. At 1920x1080, the combo delivers its best results. With Low settings, the average FPS is 299, the highest recorded for any configuration. Raising the settings to Medium reduces the average to 197 FPS, with a minimum of 167 and a maximum of 226. High settings produce an average of 187 FPS, and Ultra settings yield 178 FPS. The spread between Low and Ultra at 1080p is 121 FPS, showing that the graphical settings have a substantial impact on performance at this resolution.

At 2560x1440, the performance drops across all settings. Low settings average 255 FPS, Medium settings average 168 FPS with a minimum of 143 and a maximum of 193, High settings average 160 FPS, and Ultra settings average 152 FPS. The gap between Low and Ultra narrows to 103 FPS at 1440p compared to 1080p, indicating that the GPU is becoming more of a bottleneck as resolution increases. The minimum FPS at 1440p Medium, 143, is notably below the 144 Hz refresh rate common in gaming monitors, which could result in occasional perceptible stutters.

At 3840x2160, the performance drops further. Low settings average 204 FPS, Medium settings average 134 FPS with a minimum of 114 and a maximum of 154, High settings average 128 FPS, and Ultra settings average 122 FPS. The difference between Low and Ultra at 4K is only 82 FPS, significantly less than at 1080p. This compression of the performance range at 4K is a clear sign that the GPU is saturated and cannot differentiate between settings levels effectively. The minimum FPS of 114 at 4K Medium suggests that even at lower settings, the system will struggle to maintain high refresh rates at this resolution.

The data also shows that the Arc B370's performance is more sensitive to resolution than to settings. From 1080p Low to 1440p Low, the FPS drops by 44 FPS. From 1440p Low to 4K Low, it drops by another 51 FPS. Meanwhile, the difference between Low and Ultra at any given resolution is larger at 1080p (121 FPS) than at 4K (82 FPS). This pattern indicates that the GPU's pixel processing capabilities are the primary constraint, with texture and shading settings having less impact as resolution increases.

GPU Role

The Intel Arc B370 is an integrated graphics solution built on the Xe3-LPG architecture, manufactured on a 3 nm process by Intel. It features 1280 shading units, 40 texture mapping units, and 20 raster output units. The GPU operates at a base clock of 300 MHz and can boost to 2400 MHz. Its performance in Valorant is fundamentally limited by its memory configuration: the GPU uses System Shared memory with system-dependent bandwidth. This means the GPU is entirely reliant on the CPU's DDR4 memory bandwidth of 51.2 GB/s, which is shared with the CPU and other system processes.

The GPU's benchmark results highlight its entry-level positioning. The Arc B370 scores 1184 in the 3dmark Steel Nomad DX12 test, placing it in the 5th percentile of all GPUs. Its nearest rivals in terms of benchmark scores are all older, low-power mobile or desktop parts: the ATI Mobility Radeon HD 5570 scores 1186, the ATI Radeon HD 5770 scores 1190, and the AMD Radeon HD 7650M scores 1192. The Arc B370's score is 1.4% higher than the AMD FirePro M2000, which scores 1168. This benchmark positioning directly correlates with the Valorant results, where the GPU struggles to maintain high frame rates at higher resolutions.

The boost clock of 2400 MHz is relatively high for an integrated GPU, but the low pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s limit its ability to process the 4K resolution efficiently. The GPU's FP32 performance of 6.144 TFLOPS is modest, and in a game like Valorant, which is not graphically demanding, the GPU still becomes the bottleneck at 4K due to its limited memory bandwidth. The fact that the GPU uses system memory means that as resolution increases, the memory bandwidth requirements grow, and the shared DDR4 bandwidth becomes insufficient. This explains why the 4K results show only a small difference between Low and Ultra settings — the GPU is already saturated by the pixel fill rate requirements, not by the shading complexity.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, codenamed Renoir, manufactured on a 7 nm process at TSMC. It has a base clock of 3.70 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The CPU features 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 8 MB of shared L3 cache. It supports dual-channel DDR4 memory with a theoretical bandwidth of 51.2 GB/s, and it is unlocked for overclocking.

In Valorant, the CPU's role is to feed frames to the GPU as quickly as possible. The 4600G's benchmark scores indicate it is more than capable of this task. In Cinebench R23, it scores 13593 in multi-core and 1919 in single-core. In Geekbench, it scores 6637 multi-core and 1460 single-core. Its Passmark multi-thread score is 15992, and its single-thread score is 2653. These scores place the CPU in the 71st percentile of all CPUs, with an average benchmark score of 17507. Compared to its nearest rivals, the 4600G is essentially tied with the AMD Ryzen 3 PRO 5355GE (17482, 0.1% higher) and the Intel Core 7 150U (17395, 0.6% higher), while being 0.8% behind the Intel Core i3-14100T (17648).

The CPU's single-thread performance is particularly relevant for Valorant, which relies heavily on a single primary game thread. The 4600G's single-core score of 1919 in Cinebench R23 and 726 in 3DMark single-thread suggests it can handle the game's logic and physics calculations without becoming a bottleneck. This is confirmed by the FPS data: at 1080p Low settings, the combo achieves 299 FPS, which is likely near the CPU's maximum frame output capability before the GPU becomes the limiting factor. However, the CPU's 12 threads ensure that background processes and the game's audio and network handling do not interfere with the main game thread, maintaining consistent frame delivery.

The CPU's memory controller and cache configuration also play a role. The 8 MB of L3 cache is sufficient for Valorant's relatively small working set, and the dual-channel DDR4 memory at 51.2 GB/s provides enough bandwidth for the CPU's needs. However, the GPU shares this same memory bandwidth, creating a contention point at higher resolutions. The CPU's performance is not the issue; rather, the GPU's reliance on the same memory pool limits the overall system. The data shows that if the CPU were paired with a discrete GPU with dedicated memory, the system would likely achieve significantly higher frame rates, as the CPU's processing power is not fully utilized in the current configuration.
