Valorant

Opening Paragraph

Valorant, the 2020-released tactical FPS, is famously CPU-bound at high frame rates, yet the pairing of the AMD Ryzen 9 9900X3D and the Intel Arc B390 produces a curious inversion of that expectation. The data shows a system where the 12-core, 24-thread Zen 5 processor, with its 128 MB of L3 cache, is held back by a GPU that ranks in the 9th percentile among all graphics cards. This analysis breaks down the measured FPS across three resolutions and four quality presets, revealing a combo that is fast enough for competitive play but whose scaling characteristics are dictated almost entirely by the graphics component.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 reveals a dramatic and consistent drop in performance that points squarely at the GPU as the limiting factor. At Low settings, the average frame rate falls from 331 FPS at 1080p to 282 FPS at 1440p, a reduction of 49 FPS, and then further to 225 FPS at 4K, representing a total 106 FPS decline from the lowest to the highest resolution. This scaling pattern—a 32% drop from 1080p to 4K—is characteristic of a system where the graphics card is saturated, as the pixel count quadruples while the frame rate does not come close to halving, indicating that the CPU is not the bottleneck even at the lowest resolution.

High settings show a similar trajectory, with the average dropping from 207 FPS at 1080p to 177 FPS at 1440p, and then to 141 FPS at 4K. The 4K figure is just 68% of the 1080p performance, which is a steeper relative decline than the Low preset, suggesting that the added graphical load at High settings amplifies the GPU’s limitation. Medium settings follow the same pattern, with 218 FPS at 1080p, 186 FPS at 1440p, and 149 FPS at 4K, while Ultra settings produce 198 FPS, 169 FPS, and 135 FPS respectively. Across all presets, the gap between 1440p and 4K is consistently larger than the gap between 1080p and 1440p, a sign that the Arc B390’s rendering capabilities are being progressively overwhelmed as resolution increases.

The data indicates that the Ryzen 9 9900X3D is not the constraining component in this configuration. If the CPU were the limit, the frame rates would remain relatively flat across resolutions, as the processor’s workload is largely independent of pixel count. Instead, the consistent scaling down as resolution rises is a textbook indicator of a GPU-bound scenario. The 4K results, which hover between 135 FPS and 225 FPS depending on settings, are still playable, but the headroom for future graphical demands is minimal, and the performance ceiling is set by the Intel Arc B390’s 7.680 TFLOPS of FP32 compute and 24 ROPs.

How This Combo Ranks

In the database of tested combinations, this specific pairing of the Ryzen 9 9900X3D and the Intel Arc B390 ranks 2534 out of 2883 total combos for Valorant. That places it in the bottom 12% of all tested systems, a surprisingly low position given the presence of one of the most powerful consumer CPUs available. The combo’s percentile ranking is heavily dragged down by the GPU, which sits in the 9th percentile among all GPUs, while the CPU itself is in the 91st percentile among all processors. This stark contrast between the two components’ individual standings explains the overall poor ranking; the system’s potential is squandered by the graphics card’s inability to keep pace.

The rank of 2534 means that only 349 other combos perform worse in this game, and the vast majority of systems—over 88%—deliver higher average frame rates. This is a significant underperformance for a CPU that, in isolation, benchmarks within 0.6% of the Intel Core Ultra 5 245KF and 1.3% of the Intel Core Ultra 5 245K in average benchmark scores. The CPU’s nearest rivals in synthetic tests are all within a 2.1% delta, yet none of them are paired with a GPU as weak as the Arc B390 in this dataset. The result is a combo that is more than the sum of its parts in the wrong direction, where the CPU’s power is largely irrelevant to the final score.

The data suggests that the combo rank is not a reflection of the CPU’s capability but rather a measure of the GPU’s bottleneck. In a game like Valorant, where high frame rates are prized, the Arc B390’s 3DMark Steel Nomad DX12 score of 1482 places it just 1.3% ahead of the NVIDIA GeForce GT 520MX and 2.7% ahead of the GeForce GT 710, both of which are ancient, low-end parts. This GPU is simply not designed for the frame rates that a top-tier CPU can feed, and the combo rank of 2534 accurately captures that mismatch.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge, and built on TSMC’s 4 nm process. It operates with a base clock of 4.40 GHz and a boost clock of 5.50 GHz, with a 120 W TDP, and its defining feature is a massive 128 MB of L3 cache, which is crucial for gaming performance. In synthetic benchmarks, this CPU posts a Cinebench R23 multi-core score of 47737 and a single-core score of 6739, while its Geekbench multi-core score is 22884 and single-core is 3041. These numbers place it in the 91st percentile among all CPUs, confirming its position as a top-tier processor for both multi-threaded and single-threaded workloads.

For Valorant, the CPU’s role is to maintain the game’s simulation and input logic, which is heavily dependent on single-thread performance and cache latency. The Ryzen 9 9900X3D’s single-thread score of 1269 in 3DMark and 4646 in PassMark suggests it has ample headroom to handle the game’s engine, which typically runs on a few cores. The 3DMark 2-thread score of 2512 and 4-thread score of 4885 further indicate that even with just a handful of threads, the processor is far more capable than what the measured frame rates require. The data shows that at 1080p Low, the combo achieves 331 FPS, and the CPU is not the limit because the frame rate scales down with resolution, meaning the GPU is the bottleneck.

The cache hierarchy is particularly relevant for this game. The 128 MB of L3 cache is designed to reduce memory latency for frequently accessed data, which can improve frame pacing and minimum frame rates in CPU-bound scenarios. However, the measured data shows that the CPU’s advantages are not fully utilized. At 4K Ultra, the average FPS is 135, and at 4K Medium, the average is 149 FPS, with a minimum of 126 FPS. These figures are far below what the CPU could deliver if paired with a more powerful GPU, and they indicate that the processor is spending most of its time idle, waiting for the graphics card to finish rendering each frame. The CPU’s 24 threads and 5.50 GHz boost clock are more than sufficient for Valorant, but they are wasted in this configuration.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates, with the Low preset averaging 331 FPS. The Medium preset averages 218 FPS, with a minimum of 185 FPS and a maximum of 250 FPS. High settings average 207 FPS, while Ultra settings average 198 FPS. The gap between Low and Medium is a substantial 113 FPS, indicating that the Arc B390’s performance drops sharply with even modest graphical demands. The difference between Medium and High is just 11 FPS, and between High and Ultra is only 9 FPS, suggesting that the GPU’s performance plateaus as settings increase, likely due to its limited shader count of 1536 and texture units of 48.

Moving to 2560x1440, the frame rates decrease across all settings. Low averages 282 FPS, Medium averages 186 FPS with a minimum of 158 FPS and maximum of 214 FPS, High averages 177 FPS, and Ultra averages 169 FPS. The delta between Low and Medium at this resolution is 96 FPS, which is still large but slightly less than at 1080p. The consistency of the drop from 1080p to 1440p, approximately 49 FPS for Low and 30 FPS for High, reinforces that the GPU is the primary constraint. The minimum frame rate at 1440p Medium of 158 FPS is still well above the 60 FPS threshold for smooth gameplay, but it shows that the system can stutter under load.

At 3840x2160, the performance becomes more constrained. Low averages 225 FPS, Medium averages 149 FPS with a minimum of 126 FPS and maximum of 171 FPS, High averages 141 FPS, and Ultra averages 135 FPS. The 4K Low result is still impressive, but the 4K Ultra result of 135 FPS is only 41% of the 1080p Low result. The minimum frame rate of 126 FPS at 4K Medium is the lowest recorded in the entire dataset, and while it is still playable, it indicates that the GPU is struggling to maintain consistent frame delivery at higher resolutions. The data shows that the system is most comfortable at 1080p, where even Ultra settings exceed 190 FPS, but it becomes increasingly strained as resolution increases.

GPU Role

The Intel Arc B390 is a graphics processor based on the Xe3-LPG architecture, with the chip codenamed Panther Lake, built on Intel’s 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. The GPU operates at a base clock of 300 MHz and a boost clock of 2500 MHz, with a TDP of 80 W, and it relies on system shared memory for VRAM, which means its memory bandwidth is system dependent. Its FP32 compute capability is 7.680 TFLOPS, and its pixel rate is 60.00 GPixel/s, while its texture rate is 120.0 GTexel/s.

In the 3DMark Steel Nomad DX12 benchmark, the Arc B390 scores 1482, which places it in the 9th percentile among all GPUs. Its nearest rivals include the NVIDIA GeForce GT 520MX, which scores 1463 and is 1.3% slower, and the NVIDIA GeForce 800M, which scores 1460 and is 1.5% slower. The GeForce GT 625 OEM scores 1446, and the GeForce GT 710 scores 1443, with the Arc B390 being 2.5% and 2.7% faster, respectively. These comparisons highlight that the Arc B390 is positioned at the very bottom of the GPU performance hierarchy, alongside parts that are over a decade old and intended for basic display output rather than gaming.

The GPU’s role in Valorant is to render the game’s relatively simple, stylized graphics, which are not demanding by modern standards. However, the Arc B390’s low ROP count of 24 and its system shared memory architecture limit its fill rate and memory bandwidth, which directly impacts its ability to generate high frame rates. The measured FPS data reflects this, as the GPU’s performance drops by roughly 30% when moving from 1080p to 4K, regardless of settings. The boost clock of 2500 MHz is respectable, but the low shader count and the lack of dedicated GDDR6 memory mean that the GPU cannot sustain the frame rates that the Ryzen 9 9900X3D is capable of feeding. The 12 RT cores are irrelevant for Valorant, as the game does not use ray tracing, and the GPU’s 9th percentile ranking confirms that it is not designed for high-refresh-rate competitive gaming.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and the desired frame rate. At 1920x1080, the Low preset provides the highest average frame rate at 331 FPS, which is ideal for players with 240 Hz or 360 Hz monitors. However, the visual quality at Low is noticeably reduced, and the Medium preset at 218 FPS still offers a smooth experience for most players, with a minimum of 185 FPS ensuring no significant stutters. The High and Ultra presets at 207 FPS and 198 FPS, respectively, are also viable, but the marginal visual improvement over Medium does not justify the 11 FPS drop, so Medium is the best balance of frame rate and fidelity at 1080p.

At 2560x1440, the Low preset averages 282 FPS, which is still excellent for high-refresh-rate displays. The Medium preset at 186 FPS, with a minimum of 158 FPS, is the recommended choice for most users, as it provides a significant visual upgrade over Low with only a 96 FPS penalty. High at 177 FPS and Ultra at 169 FPS are also playable, but the frame rate drops below 170 FPS, which may not be sufficient for the most demanding competitive players. For 1440p, Medium is the sweet spot, as it maintains an average above 180 FPS while offering better lighting and texture quality than Low.

At 3840x2160, the situation is more challenging. The Low preset at 225 FPS is the only setting that delivers a frame rate above 200 FPS, making it the clear choice for players who prioritize performance over visuals at 4K. Medium at 149 FPS, with a minimum of 126 FPS, is the highest setting that keeps the average above 144 FPS, which is the threshold for many high-refresh-rate 4K monitors. High at 141 FPS and Ultra at 135 FPS are both below this threshold, and the minimum frame rates are not measured, but the averages suggest they may dip below 120 FPS during intense scenes. For 4K, the Medium preset is the recommended maximum, as it balances the visual improvements with a frame rate that remains above 144 FPS on average, while Low is the best for competitive play.
