Valorant

Valorant on the AMD Ryzen 7 5700X3D and Intel Arc B390 combination delivers a playable experience, but the data reveals a significant performance ceiling dictated by the graphics solution. The measured frame rates are consistently high enough for competitive play at all tested resolutions, yet the scaling patterns show that the Intel Arc B390 struggles under increased graphical loads, preventing the powerful CPU from reaching its full potential. The combination ranks in the 12th percentile of tested systems, indicating that while this pairing is functional, it is far from optimal for maximizing Valorant's performance.

Resolution Scaling

The frame rate drop from 1080p to 4K is the defining characteristic of this hardware pairing. At 1080p with Low settings, the system achieves 331 FPS, but this falls to 225 FPS at 4K Low—a reduction of 106 FPS, or roughly 32%. This substantial decrease when the resolution increases points directly to the GPU as the primary bottleneck, as the CPU's workload does not scale with resolution in the same way.

The pattern becomes more pronounced when examining the High settings preset. At 1920x1080, the average FPS is 207, which drops to 177 at 2560x1440, and further to 141 at 3840x2160. This represents a cumulative decline of 66 FPS from 1080p to 4K. The scaling is nearly linear with the pixel count increase, which is a classic indicator that the Intel Arc B390 is operating at its limits. The GPU's 7.680 TFLOPS of FP32 performance and 24 ROPs are simply not sufficient to maintain higher frame rates as the pixel throughput demands increase.

Interestingly, the gap between Low and Medium settings is relatively small at each resolution. At 4K, Low produces 225 FPS while Medium produces 149 FPS—a difference of 76 FPS. This suggests that the transition from Low to Medium introduces enough additional graphical complexity to significantly impact the GPU. The Ultra preset further compounds this, yielding 135 FPS at 4K, which is the lowest measured result across all configurations. The data shows that the Intel Arc B390 is most comfortable at Low settings, where it can leverage its 1536 shading units more efficiently without the overhead of advanced rendering techniques.

The limiting component is unequivocally the GPU. The CPU, with its 8 cores and 16 threads based on Zen 3 architecture, is more than capable of handling the frame generation at these resolutions. The 96 MB of shared L3 cache provides a substantial advantage for game logic and physics calculations. However, the GPU's 300 MHz base clock and 2500 MHz boost clock cannot keep pace with the CPU's instruction throughput when resolution scaling increases the fragment processing load. The result is a system where the CPU sits idle waiting for the GPU to complete its rendering tasks.

CPU Role

The AMD Ryzen 7 5700X3D is a desktop processor from the 5000 series, built on the Zen 3 architecture with the Vermeer codename. It features 8 cores and 16 threads, with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. The processor is manufactured on a 7 nm process by TSMC, with 8,850 million transistors on a 74 mm² die. This CPU is designed for gaming, evidenced by its 96 MB of shared L3 cache, which is significantly larger than typical desktop processors.

In Valorant, the CPU's role is to handle game logic, player positions, and input processing. The benchmark results indicate that the Ryzen 7 5700X3D is well-equipped for this task. Its Cinebench R23 multicore score of 22366 demonstrates strong multi-threaded performance, which is relevant for background tasks and game server processing. The single-core score of 3157 is more crucial for Valorant, as the game's engine typically relies on a few primary threads for rendering commands and physics.

The CPU's percentile ranking of 77 places it above the majority of tested processors. Compared to its nearest rivals, the Ryzen 7 5700X3D's average benchmark score of 24709 is nearly identical to the AMD Ryzen 5 7600X3D, which scores 24728—a delta of -0.1%. It also closely matches the AMD Ryzen 9 5900HX (24822, -0.5%), the Intel Core i5-12450HX (24576, +0.5%), and the Intel Core i5-11600 (24563, +0.6%). These differences are negligible in real-world gaming scenarios.

The 105W TDP and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for feeding the GPU with data. However, the data suggests that the CPU is not the constraint in this system. At 1080p Low, the system achieves 331 FPS, which is likely near the CPU's maximum frame generation capability for this game. Yet, when the resolution increases, the CPU's utilization likely decreases as the GPU becomes the limiting factor, leaving the CPU's ample resources underutilized.

How This Combo Ranks

The combo rank for this specific pairing in Valorant is 2534 out of 2883 tested combinations. This ranking places the system in the 12th percentile of all tested combos, which is a poor result for a game that is known for being CPU-intensive and relatively easy on GPUs. The high rank number indicates that the vast majority of other tested CPU and GPU pairings achieve higher average FPS in Valorant.

This low ranking is directly attributable to the Intel Arc B390's performance. The GPU's percentile ranking against all GPUs is 9, meaning it performs better than only 9% of all tested graphics cards. Its average benchmark score of 1482 is based on a single 3DMark Steel Nomad DX12 test, which places it in the company of much older and less capable GPUs like the NVIDIA GeForce GT 520MX (1463, +1.3%), GeForce 800M (1460, +1.5%), GT 625 OEM (1446, +2.5%), and GT 710 (1443, +2.7%).

In the context of Valorant, this ranking means that users with more balanced systems, such as a mid-range CPU paired with a discrete GPU from the past five years, would likely see higher frame rates. The Ryzen 7 5700X3D is a high-end CPU that can push well over 400 FPS in Valorant when paired with a capable GPU. However, the Arc B390, which is an integrated graphics solution with a 80W TDP and system-shared memory, cannot deliver the pixel throughput necessary to match the CPU's potential.

The data shows a clear mismatch: a 77th percentile CPU paired with a 9th percentile GPU. This results in a combo that ranks in the 12th percentile overall. For users aiming for competitive play at high refresh rates, this combination would likely disappoint, as the GPU bottleneck prevents the system from achieving the frame rates that the CPU alone could support.

GPU Role

The Intel Arc B390 is a graphics solution based on the Xe3-LPG architecture, with the chip codename Panther Lake. It is manufactured on a 3 nm process by Intel and features 1536 shading units, 48 TMUs, and 24 ROPs. The GPU also includes 12 ray tracing cores and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its clock speeds are 300 MHz base and 2500 MHz boost, with a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s.

The most critical limitation is its memory configuration. The GPU uses "System Shared" memory, meaning it relies on the system's DDR4 RAM rather than dedicated VRAM. This is a significant disadvantage for gaming, as shared memory bandwidth is "System Dependent" and typically much lower than dedicated GDDR6 or GDDR6X memory. This shared memory setup likely contributes to the GPU's low benchmark scores and its inability to handle higher resolutions and settings efficiently.

In Valorant, the GPU's role is to render the 3D scene, apply textures, and output frames. The measured FPS data shows that the GPU is the primary bottleneck across all settings. At 4K Ultra, the system only achieves 135 FPS, which is the lowest result. The GPU's 7.680 TFLOPS of FP32 performance is not sufficient for the pixel shading workload at this resolution. The texture rate of 120.0 GTexel/s and pixel rate of 60.00 GPixel/s are modest figures that limit the GPU's ability to fill the screen with detailed graphics.

The GPU's performance is best at Low settings, where it can achieve 331 FPS at 1080p. However, this is still below what a dedicated mid-range GPU would deliver. The GPU's nearest rivals in terms of 3DMark scores are all NVIDIA GPUs from over a decade ago, such as the GT 520MX and GT 710. This comparison highlights the Arc B390's position as a low-end graphics solution, likely intended for basic computing tasks rather than gaming.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system's performance across three resolutions and four quality presets. At 1920x1080, the system achieves 331 FPS on Low, 218 FPS on Medium, 207 FPS on High, and 198 FPS on Ultra. The Medium preset shows a minimum of 185 FPS and a maximum of 250 FPS, indicating a range of 65 FPS during gameplay.

At 2560x1440, the frame rates decrease noticeably. Low settings produce 282 FPS, which is still very high. Medium settings yield an average of 186 FPS, with a minimum of 158 and a maximum of 214 FPS. High settings drop to 177 FPS, while Ultra settings produce 169 FPS. The scaling from 1080p to 1440p shows an average reduction of approximately 15-20% across settings, which is consistent with the increased pixel count.

At 3840x2160, the performance impact is severe. Low settings produce 225 FPS, which is a substantial drop from the 1080p Low result. Medium settings average 149 FPS, with a minimum of 126 and a maximum of 171 FPS. High settings yield 141 FPS, and Ultra settings produce 135 FPS. The difference between 1080p Low and 4K Low is 106 FPS, whereas the difference between 1080p Ultra and 4K Ultra is 63 FPS. This suggests that the GPU is already saturated at Ultra settings even at 1080p, so the additional resolution has a smaller relative impact.

The data reveals that the system is best suited for 1080p gaming, where it can maintain frame rates above 198 FPS even at Ultra settings. For 1440p, users would need to stick to Low or Medium settings to stay above 180 FPS. At 4K, the system falls below 150 FPS at Medium settings and above, which may not be ideal for competitive play where high refresh rates are preferred. The minimum FPS readings at Medium settings show that the system can experience drops of up to 30% from the average, which could cause noticeable stutters in fast-paced scenarios.
