Doom

The AMD Ryzen 5 7600X paired with the Intel Arc B580 presents a fascinating case study in 1080p and 1440p gaming, but the data suggests that the graphics card becomes the primary bottleneck as resolution climbs. The measured frames per second (FPS) reveal a system that is exceptionally capable at lower resolutions, yet struggles to maintain high refresh rates at 4K. This analysis breaks down the performance metrics from the FACT PACK to understand the dynamic between this 6-core processor and the 12 GB graphics card.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, indicating that the Intel Arc B580 is the limiting component at higher resolutions. At Low settings, the average frame rate falls from 183.4 FPS at 1920x1080 to 64.4 FPS at 3840x2160, a reduction of nearly 65%. This dramatic scaling is typical of a GPU-bound scenario, where the rendering workload increases exponentially with pixel count.

The pattern holds across all quality presets. At High settings, the drop is from 137.8 FPS at 1080p to 47.7 FPS at 4K. At Ultra, the numbers fall from 109.3 FPS to 41.9 FPS. The fact that the 1080p results are so high—even exceeding 180 FPS on Low—suggests that the CPU is not the primary constraint at that resolution. The Ryzen 5 7600X has enough headroom to feed the GPU at lower resolutions, but the Arc B580 simply cannot maintain that throughput when the pixel count quadruples.

The scaling between 1440p and 4K is particularly telling. At Medium settings, 2560x1440 yields 104.9 FPS, while 3840x2160 drops to 55.4 FPS. This near-halving of performance points to the GPU's memory bandwidth and compute resources being saturated. The Arc B580's 456.0 GB/s bandwidth and 13.67 TFLOPS of FP32 performance are sufficient for 1440p but are stretched thin at 4K, especially with higher quality settings enabled.

How This Combo Ranks

The combo rank in Doom places this pairing at position 1298 out of 1681 tested combinations. This percentile placement is notable because it suggests that while the individual components are solid mid-range performers, the combination is not optimized for this specific title. The rank of 1298 out of 1681 means that roughly 77% of tested combos deliver higher frame rates in Doom.

This ranking likely reflects the fact that Doom is a well-optimized game that favors high single-thread performance and raw GPU power. The Ryzen 5 7600X, with its 83rd percentile ranking among all CPUs, is hardly a weak link. However, the Arc B580's 66th percentile among GPUs indicates that the graphics card is the more modest performer in this duo. The composite result is a system that lands in the lower-middle tier of tested combos, despite having a strong processor.

The nearest rivals for the GPU are instructive here. The Arc B580 sits within 0.7% of the NVIDIA GeForce RTX 4060 in average benchmark scores, yet the combination ranking suggests that Doom-specific performance may not align perfectly with synthetic benchmarks. The data implies that while the Arc B580 is competitive in general compute tasks, its driver optimization or architectural quirks may hold it back in this particular game engine.

CPU Role

The Ryzen 5 7600X brings six cores and twelve threads to the table, running at a base clock of 4.70 GHz with a boost clock of 5.30 GHz. This Zen 4 architecture, built on a 5 nm process, is designed for high clock speeds and strong single-threaded performance. The benchmark data supports this: the Cinebench R23 single-core score of 3406 is robust, and the 3DMark single-thread score of 1060 indicates solid per-core capability.

In Doom, a game that scales well with CPU speed but doesn't heavily utilize many cores, the 7600X's characteristics are well-suited. The 1080p Low setting result of 183.4 FPS reflects the CPU's ability to feed frames rapidly. Even at 1080p Ultra, the 109.3 FPS result shows that the processor is not the limiting factor at this resolution.

The CPU's 32 MB of shared L3 cache and dual-channel DDR5 memory support contribute to its responsiveness. The 83.2 GB/s memory bandwidth is ample for gaming workloads. At 1440p, the CPU's role diminishes as the GPU takes over the performance burden. The fact that frame rates at 1440p High (88.1 FPS) are significantly lower than 1080p Low (183.4 FPS) confirms that the GPU is the primary driver of performance differences at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the system delivers excellent performance across all settings. Low settings produce an average of 183.4 FPS, Medium yields 159 FPS, High reaches 137.8 FPS, and Ultra still manages 109.3 FPS. These numbers indicate a smooth experience for high-refresh-rate monitors, with even the most demanding preset staying above the 100 FPS threshold.

Moving to 2560x1440, the results are still strong but show clear scaling. Low settings average 119.9 FPS, Medium drops to 104.9 FPS, High falls to 88.1 FPS, and Ultra bottoms out at 72.8 FPS. This resolution is the sweet spot for this combo, offering a balance between visual fidelity and playability. The drop from 1080p to 1440p is roughly 35% across settings, which is reasonable given the increased pixel count.

At 3840x2160, the system struggles to maintain smooth frame rates. Low settings average 64.4 FPS, Medium drops to 55.4 FPS, High falls to 47.7 FPS, and Ultra is borderline unplayable at 41.9 FPS. These numbers are below the 60 FPS target for most gamers, even on Low settings. The 4K results illustrate the GPU's limitations clearly, as the Arc B580 is not designed for high-refresh-rate 4K gaming in demanding titles.

GPU Role

The Intel Arc B580 is a 12 GB GDDR6 graphics card with a 192-bit memory bus, delivering 456.0 GB/s of bandwidth. Its base and boost clocks are both 2670 MHz, which is a relatively high operating frequency for a mid-range GPU. The card features 2560 shading units and 80 ROPs, with a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s.

The GPU's performance in Doom is characterized by its 66th percentile ranking among all GPUs. The PassMark G3D score of 15748 and the 3DMark Steel Nomad DX12 score of 3068 indicate solid DirectX 12 performance, which is relevant for a modern title like Doom. However, the card's FP32 throughput of 13.67 TFLOPS is modest compared to higher-tier options, which explains the 4K performance drop.

The 12 GB VRAM is more than sufficient for Doom at any resolution, as the game is not VRAM-hungry at these settings. The memory bandwidth of 456.0 GB/s is also adequate for 1440p, but at 4K, the GPU's compute resources become the limiting factor. The card's 20 ray tracing cores and 160 TMUs are present, but Doom's traditional rasterization path doesn't heavily utilize these features, so the raw pixel throughput becomes the deciding factor.
