# Undisputed with AMD Ryzen 5 7600X + Intel Arc B390

This combo pairs AMD's 6-core Zen 4 desktop processor with Intel's integrated-class Arc B390 graphics, and the measured frame rates in Undisputed tell a clear story: the GPU is the overwhelming bottleneck at every resolution tested. The Ryzen 5 7600X is a strong mid-range CPU, but the Arc B390's performance profile places it near the bottom of the GPU hierarchy, and that is exactly what the FPS data reflects across all three resolutions.

Resolution Scaling

The measured FPS data shows a steep and consistent penalty as resolution increases, which is the classic signature of a GPU-bound scenario. At 1080p Low, the combo produces 127 FPS average. Moving to 1440p Low drops that to 92 FPS, a 28% reduction. At 4K Low, the average falls to 58 FPS, which is 54% below the 1080p Low result. These are large drops for a settings tier that typically stresses the GPU more than the CPU, and they confirm that the Arc B390's rendering throughput is the limiting factor.

The pattern repeats across all settings presets. At High settings, 1080p delivers 76 FPS, 1440p drops to 55 FPS, and 4K falls to 35 FPS. The gap between 1080p and 4K at High settings is 54%, nearly identical to the Low settings drop. Medium settings show 91 FPS at 1080p, 66 FPS at 1440p, and 42 FPS at 4K, with the 1080p-to-4K loss at 54% again. Ultra settings produce 49 FPS at 1080p, 35 FPS at 1440p, and 22 FPS at 4K — a 55% loss from 1080p to 4K.

The consistency of these percentage drops across all four settings tiers is telling. If the CPU were a meaningful constraint at lower resolutions, you would expect the 1080p-to-1440p drop to be smaller than the 1440p-to-4K drop, because the CPU would hold frame rates up at 1080p. Instead, the data shows a uniform scaling curve, which indicates that the GPU is saturated even at 1080p. The Arc B390 simply cannot feed frames fast enough to let the Ryzen 5 7600X stretch its legs.

Another way to read this is that the 1080p Low result of 127 FPS is the only measured point that approaches what this CPU is capable of in a less demanding scenario. The Ryzen 5 7600X has a single-thread benchmark score of 1060 in 3DMark and a PassMark single-thread score of 4135, so it is not the constraint here. The frame rate ceiling in Undisputed is set by the GPU at every resolution and settings combination tested.

How This Combo Ranks

The combo finishes at rank 2491 out of 2813 tested combos in Undisputed, placing it in the bottom 11% of all configurations in the database. That is a low standing, but it is not surprising given the GPU's performance percentile. The Intel Arc B390 sits at the 9th percentile among all GPUs, which means roughly nine out of ten GPUs in the database outperform it. The combo's rank is therefore a direct reflection of the GPU's position, rather than a statement about the CPU.

To put that in context, the Arc B390's nearest rivals in the GPU benchmark database are all older or lower-end NVIDIA parts. The GeForce GT 520MX scores 1463 on the 3DMark Steel Nomad test, which is 1.3% behind the Arc B390's 1482. The GeForce 800M scores 1460 (1.5% behind), the GeForce GT 625 OEM scores 1446 (2.5% behind), and the GeForce GT 710 scores 1443 (2.7% behind). These are all integrated or entry-level discrete GPUs from a decade ago, which tells you the Arc B390 is competing in the absolute entry tier of graphics performance.

The CPU side is a different story. The Ryzen 5 7600X sits at the 79th percentile among all CPUs, and its nearest rivals are all respectable mid-range parts. The AMD Ryzen 7 5700X and Intel Core i5-12600K both have an average benchmark score of 27578, which is 0.2% higher than the 7600X's 27636. The AMD Ryzen 5 8500GE scores 27712 (0.3% higher), and the AMD Ryzen 7 5800 scores 27535 (0.4% lower). This places the 7600X in a tight cluster of capable processors, all within a fraction of a percent of each other.

The mismatch between the CPU's 79th percentile ranking and the GPU's 9th percentile ranking is the defining characteristic of this combo. In Undisputed, the data shows that the combo's 2491st rank out of 2813 is entirely attributable to the GPU. With a different GPU, this CPU would likely rank much higher, but as configured, the Arc B390 drags the whole system down to near the bottom of the database.

GPU Role

The Intel Arc B390 is based on the Panther Lake chip with Xe3-LPG architecture, built on Intel's 3 nm process. It has 1536 shading units, 48 texture mapping units, and 24 ROPs, along with 12 ray tracing cores. Its base clock is 300 MHz with a boost clock of 2500 MHz. The memory configuration is system shared, meaning it uses the host system's RAM rather than dedicated VRAM, and the memory bandwidth is listed as system dependent.

The GPU's raw compute figures are modest. It delivers 7.680 TFLOPS of FP32 performance and 15.36 TFLOPS of FP16 (2:1 ratio). The pixel rate is 60.00 GPixel/s and the texture rate is 120.0 GTexel/s. These are not numbers that suggest high-end gaming performance, and the measured FPS in Undisputed confirms that expectation.

The system shared memory is a significant factor for this game. Undisputed is a sports title that likely benefits from having dedicated VRAM, but the Arc B390 has none — it relies on shared system memory, which is system dependent for bandwidth. This creates a situation where the GPU's performance can vary depending on the host system's memory speed and configuration. In this case, the Ryzen 5 7600X supports dual-channel DDR5 with 83.2 GB/s memory bandwidth, so the shared memory should be relatively fast, but it still cannot match the bandwidth of dedicated VRAM.

The GPU's single benchmark score is 1482 on 3DMark Steel Nomad DX12, which places it at the 9th percentile. Its nearest rival, the GT 520MX, is 1.3% behind, and the gap to the next few rivals is only 1.5% to 2.7%. This shows that the Arc B390 is essentially at the floor of GPU performance in the database, with almost nothing below it in terms of benchmark scores.

In Undisputed, the GPU's limitations are visible in the FPS scaling. At 4K Ultra, the combo manages only 22 FPS average, which is not playable. Even at 1080p Ultra, the 49 FPS average is borderline. The GPU's performance is so constrained that it cannot maintain playable frame rates at higher settings, regardless of resolution.

Settings Recommendations

The measured data provides a clear picture of which settings are viable for this combo. At 1080p, the Medium preset delivers 91 FPS average with a minimum of 78 FPS and a maximum of 105 FPS. This is the most balanced setting in the measured rows, offering smooth gameplay with a comfortable margin above 60 FPS. The High preset at 1080p drops to 76 FPS average, which is still playable but with less headroom for demanding scenes.

At 1440p, the Medium preset produces 66 FPS average with a minimum of 56 FPS and a maximum of 76 FPS. This is playable but close to the 60 FPS threshold, and the minimum frame rate suggests occasional dips below that mark. The Low preset at 1440p delivers 92 FPS average, which is smoother, but you sacrifice visual quality to get there. The High preset at 1440p drops to 55 FPS average, which is below the 60 FPS threshold and likely to feel less fluid.

At 4K, no settings preset achieves a 60 FPS average. The Low preset comes closest at 58 FPS, followed by Medium at 42 FPS, High at 35 FPS, and Ultra at 22 FPS. If 4K is the target resolution, the Low preset is the only playable option, and even that is marginal.

For the best experience, the 1080p Medium preset is the recommended configuration based on the measured rows. It provides the highest average FPS above 60 with a minimum of 78 FPS, meaning it should maintain smooth gameplay throughout most scenes. If you prefer higher visual fidelity, 1080p High at 76 FPS average is a reasonable alternative, but the Medium preset offers better frame time consistency based on the minimum FPS data.

For 1440p users, the Medium preset at 66 FPS average is the best balance of quality and performance, but be aware that the 56 FPS minimum indicates potential dips below 60 FPS. The Low preset at 92 FPS average is the safer choice if you prioritize smoothness over visuals. For 4K, the Low preset at 58 FPS average is the only viable option, and even that is borderline.

CPU Role

The AMD Ryzen 5 7600X is a 6-core, 12-thread processor from the 7000 series, based on the Zen 4 architecture with the Raphael codename. It is built on TSMC's 5 nm process with 6,570 million transistors on a 71 mm² die. The base clock is 4.70 GHz with a boost clock of 5.30 GHz, and it has a 105 W TDP. The cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache.

In Undisputed, the CPU's role is to feed the GPU with draw calls and game logic, and the data suggests it is doing that job effectively. The 7600X scores 1965 on Cinebench R23 single-core and 15236 on multi-core, which are strong numbers for a 6-core part. Its PassMark single-thread score is 4135, and its 3DMark single-thread score is 1060. These results place it at the 79th percentile among all CPUs, meaning it outperforms the majority of processors in the database.

The CPU's nearest rivals are all within 0.4% of its average benchmark score of 27636. The Ryzen 7 5700X and Core i5-12600K both score 27578 (0.2% higher), the Ryzen 5 8500GE scores 27712 (0.3% higher), and the Ryzen 7 5800 scores 27535 (0.4% lower). This tight grouping shows that the 7600X is a solid mid-range performer that trades blows with other capable CPUs in its class.

However, in this specific combo, the CPU's performance is largely irrelevant to the gaming experience because the GPU is so weak. The measured FPS in Undisputed never exceeds 127 FPS even at 1080p Low, which is far below what this CPU could deliver with a more capable GPU. The consistent FPS drops across resolutions and settings confirm that the CPU is not the limiting factor in any of the 12 measured configurations.

The 7600X supports PCIe Gen 5 with 24 lanes from the CPU, which provides ample bandwidth for a discrete GPU. It also supports DDR5 memory with dual-channel configuration and 83.2 GB/s bandwidth, which is beneficial for the Arc B390's system shared memory architecture. The CPU's integrated Radeon Graphics are present but not used for gaming in this config, as the Arc B390 handles display output.

In summary, the Ryzen 5 7600X is a capable CPU that is wasted in this pairing for Undisputed. Its performance characteristics are strong, but the Arc B390's 9th percentile GPU ranking means the combo ranks 2491st out of 2813 in this game. If you have this CPU, the data suggests you would benefit significantly from pairing it with a more powerful GPU to unlock its full potential in Undisputed.
