Doom

The AMD Ryzen 7 7800X3D paired with the Intel Arc B570 presents a distinctive performance profile in Doom, one that is heavily dictated by resolution and graphics preset. The measured frame rates reveal a system that is clearly capable of high refresh rate gaming at 1080p but becomes increasingly constrained by the graphics card as pixel count rises. This analysis breaks down the measured data to show exactly where this combination excels and where its limitations appear.

Resolution Scaling

The transition from 1080p to 4K produces a dramatic and telling drop in average frame rates across all settings, clearly identifying the Intel Arc B570 as the primary bottleneck at higher resolutions. At the High preset, the system delivers 121 FPS at 1920x1080, but this falls to 78 FPS at 2560x1440, a 35.5% reduction. Moving to 3840x2160, the average plummets to 42 FPS, which is just 34.7% of the 1080p performance. This scaling pattern is characteristic of a GPU-bound scenario where the render load increases exponentially with pixel count, overwhelming the Arc B570's 10 GB of GDDR6 memory and 160-bit bus.

The Low preset tells a similar story but with slightly more headroom at each step. The system achieves 164 FPS at 1080p, drops to 106 FPS at 1440p (a 35.4% decrease), and then falls to 57 FPS at 4K. Interestingly, the percentage drop from 1440p to 4K is 46.2%, which is nearly identical to the 46.1% drop seen on the High preset between those same resolutions. This consistency suggests that the GPU's compute and memory subsystems are saturated in a similar fashion regardless of the visual complexity, with the lower preset simply shifting the entire curve upward.

What is particularly revealing is the Ultra preset's behavior. At 1080p, Ultra yields 99 FPS, which is 22.2% lower than High. At 1440p, Ultra drops to 64 FPS, a 35.4% reduction from 1080p Ultra. The 4K Ultra result of 35 FPS represents a staggering 64.6% loss from the 1080p Ultra figure. This indicates that the Ultra preset introduces effects that are disproportionately expensive at high pixel counts, likely related to the Arc B570's 80 ROPs and 360.0 GTexel/s texture rate being insufficient for the combined load of maximum settings and 8.3 million pixels.

The data shows that the CPU, despite its 8 cores and 16 threads, is not the limiting factor in this scaling. The Ryzen 7 7800X3D's boost clock of 5.00 GHz and 96 MB of shared L3 cache provide ample single-thread performance, as evidenced by the 164 FPS result at 1080p Low. If the CPU were the constraint, we would expect to see frame rates plateau as resolution decreases; instead, they continue to climb, confirming that the Arc B570's 11.52 TFLOPS FP32 compute is the ceiling.

Settings Recommendations

Based on the measured rows, the Medium preset offers the most balanced experience across all three resolutions. At 1080p, Medium produces 143 FPS with a minimum of 121 FPS, which is only 12.8% lower than Low but 18.1% higher than High. This suggests that Medium captures most of the visual uplift from Low while avoiding the performance penalty of High. The 121 FPS minimum is still comfortably above 120 Hz, making this an excellent choice for high-refresh displays.

At 1440p, Medium delivers 92 FPS with a minimum of 79 FPS. While this is below the 106 FPS achieved on Low, the 13.2% performance cost for the visual improvement is reasonable. The 79 FPS minimum indicates that the Arc B570 can maintain a playable experience even during demanding scenes, though users with 144 Hz monitors will need to accept that they cannot fully utilize their display's refresh rate at this resolution.

The 4K Medium result of 50 FPS (minimum 43 FPS) is the only 4K setting that approaches playability. The Ultra preset's 35 FPS average is likely to feel stuttery in fast-paced action, and even High's 42 FPS sits below the 60 FPS threshold many consider standard. Low at 4K reaches 57 FPS, which is technically smooth but sacrifices significant visual fidelity. For users prioritizing a consistent 60 FPS at 4K, the data suggests that Low is the only viable option, while Medium offers a compromise at 50 FPS that may be acceptable for slower-paced sections.

The Ultra preset, despite being the highest quality option, provides the worst experience-per-frame ratio. Compared to High, Ultra reduces performance by 18.2% at 1080p, 17.9% at 1440p, and 16.7% at 4K. Given that the Arc B570 is not a high-end GPU (its percentileVsAllGpus is 65), the additional visual features in Ultra are not worth the frame rate sacrifice. Medium is the recommended preset for most users, with Low as a fallback for 4K or high-refresh 1440p gaming.

CPU Role

The AMD Ryzen 7 7800X3D is a processor designed for gaming workloads, and its specifications align well with Doom's engine requirements. The 8 cores and 16 threads are more than sufficient for a game released in 2016, even at maximum settings. The processor's architecture, Zen 4 on the Raphael codename, features a base clock of 4.20 GHz and a boost clock of 5.00 GHz, providing strong single-thread performance that is crucial for game logic and draw call submission. The 96 MB of shared L3 cache is particularly beneficial, as it reduces memory latency for frequently accessed game data.

The CPU's 3DMark results support its capability in gaming scenarios. The single-thread score of 959 and the 2-thread score of 1887 indicate that the processor can handle the primary rendering thread plus a secondary helper thread without bottlenecking. The 8-thread score of 6539 shows scaling efficiency, and the max-thread score of 7967 confirms that even fully loaded, the CPU maintains high throughput. In Doom, which typically utilizes 4-8 threads effectively, the 7800X3D is unlikely to be the limiting component at any resolution tested.

This is confirmed by the measured FPS data. At 1080p Low, the system achieves 164 FPS, which is a high frame rate that would expose CPU limitations if present. The fact that performance continues to scale with resolution (dropping to 106 FPS at 1440p and 57 FPS at 4K) indicates that the GPU is the binding constraint. Even at 1080p Ultra, the 99 FPS result is well above what a weaker CPU could deliver, proving that the 7800X3D's 5.00 GHz boost clock and large cache are more than adequate for this title.

The processor's memory bandwidth of 83.2 GB/s over a dual-channel DDR5 interface is also sufficient for feeding the Arc B570. The GPU's 380.0 GB/s memory bandwidth is significantly higher, but the CPU does not need to match this; it only needs to provide data fast enough to avoid starving the GPU. The benchmark results, particularly the Geekbench multi-core score of 15610 and Cinebench R23 multi-core score of 16817, position the 7800X3D as a high-end desktop part (percentileVsAllCpus of 83) that pairs well with mid-range GPUs like the Arc B570.

How This Combo Ranks

In the benchmark database's ranking for Doom, this combination of the Ryzen 7 7800X3D and Intel Arc B570 holds a comboRankInGame of 2332 out of 2930 tested combos. This places it in the 20.4th percentile of all configurations, meaning that roughly 79.6% of tested combos achieve higher average frame rates in this game. This ranking is notably lower than the individual component percentiles (CPU at 83, GPU at 65), which suggests that the pairing is suboptimal for Doom's specific workload.

The low rank is primarily attributable to the GPU's performance class. The Arc B570's average benchmark score of 20556 places it near the NVIDIA GeForce RTX 3070 Mobile, which scores 20534 (a deltaPct of 0.1%), and the Intel Arc A750 at 20582 (deltaPct of -0.1%). These are mid-range GPUs that, while capable at 1080p, do not have the raw compute or memory bandwidth to sustain high frame rates at 4K. The GPU's percentileVsAllGpus of 65 means it outperforms 65% of all GPUs, but in Doom, which is a well-optimized title that can scale to high refresh rates, the demand is for higher-end hardware.

The CPU's nearest rivals provide context for its contribution to the combo. The Ryzen 7 8700G and Intel Core i7-13650HX both have an average score of 33089, matching the 7800X3D's 33089 (deltaPct of 0). The AMD Ryzen 9 PRO 6950H scores 33201, which is 0.4% higher. These similar scores indicate that the 7800X3D is not a unique performance outlier; it is one of many capable processors that do not differentiate the combo's ranking. The ranking is therefore almost entirely determined by the GPU, which is why the combo falls below 80% of tested configurations.

It is worth remembering the comboRankInGame of 2332 does not necessarily imply poor performance in absolute terms. The measured FPS at 1080p (121-164 FPS depending on preset) is quite playable, and even 1440p High at 78 FPS is acceptable. The ranking is relative to all combos, many of which feature much more powerful GPUs like the RTX 4080 or RX 7900 XTX. For a mid-range GPU like the Arc B570, the ranking is expected, but users should be aware that this combo is not designed for maximum 4K performance.

GPU Role

The Intel Arc B570, based on the Xe2-HPG architecture and codenamed Battlemage, is the clear performance limiter in this combination. Its specifications reveal a mid-range part designed for 1080p and entry-level 1440p gaming. The GPU features 2304 shading units, 144 TMUs, and 80 ROPs, with a base and boost clock of 2500 MHz. This configuration yields 11.52 TFLOPS of FP32 compute, 360.0 GTexel/s texture rate, and 200.0 GPixel/s pixel rate. These figures are respectable for the segment but insufficient for demanding 4K workloads.

The memory subsystem is a critical constraint. The 10 GB of GDDR6 memory on a 160-bit bus provides 380.0 GB/s of bandwidth. While this is adequate for 1080p and 1440p, the 4K resolution requires the GPU to access significantly more texture and geometry data, and the bandwidth becomes a bottleneck. The measured FPS data supports this: at 4K, even the Low preset only achieves 57 FPS, whereas at 1080p Low, it reaches 164 FPS. The 65.2% performance drop when moving from 1080p to 4K on Low settings far exceeds what would be seen on a higher-bandwidth GPU.

The GPU's benchmark scores contextualize its performance. The 3DMark Steel Nomad DX12 score of 2649 and the PassMark G3D score of 14195 place it in the mid-range tier. The Geekbench Vulkan score of 96844 suggests good compute capability, but Doom is primarily a rasterization workload. The GPU's 18 RT cores are present but underutilized in this game, as Doom does not feature ray tracing. The DirectX 12 PassMark score of 72 indicates that the GPU's DX12 implementation is functional but not exceptional, which is relevant since Doom uses OpenGL and Vulkan.

The Arc B570's TDP of 150 W and its PCIe 4.0 x8 interface are not limiting factors in this game. The 8-lane interface provides sufficient bandwidth for the GPU's data requirements, and the 150 W power budget allows the card to sustain its 2500 MHz boost clock under load. The GPU's 5 nm process node and 19,600 million transistors on a 272 mm² die indicate a modern design, but the transistor density of 72.1M / mm² suggests that the design is optimized for efficiency rather than raw throughput. This is reflected in the measured FPS, where the GPU consistently underperforms what a high-end card would achieve.

| 1920x1080 | Ultra | 99 | — |

At 1920x1080, the system delivers smooth frame rates across all presets. The Low preset's 164 FPS average is ideal for 144 Hz displays, while Medium's 143 FPS with a 121 FPS minimum still offers a high-refresh experience. High at 121 FPS is also excellent, and even Ultra's 99 FPS is playable on most monitors. The 1080p results clearly indicate that this combo is well-suited for competitive or fast-paced gameplay at this resolution.

The 2560x1440 results show a step down in performance. Low at 106 FPS is good, and Medium at 92 FPS (minimum 79 FPS) remains fluid. High at 78 FPS is acceptable for most players, though those with 144 Hz displays will notice the difference. Ultra at 64 FPS is borderline, but for a game like Doom where reaction speed matters, dropping to High or Medium is recommended for a more consistent experience.

The 3840x2160 results are the most constrained. Low at 57 FPS is the only setting that achieves near-60 FPS performance. Medium at 50 FPS (minimum 43 FPS) is playable but may exhibit occasional stutter in intense combat. High at 42 FPS and Ultra at 35 FPS fall below the 60 FPS standard and are likely to feel sluggish. For 4K gaming, users should accept the visual compromises of Low or Medium settings to maintain playable frame rates.
