GPU Role

The Intel Arc B580 is built on the Xe2-HPG architecture using a 5 nm process from TSMC, with the BMG-G21 chip housing 19,600 million transistors on a 272 mm² die. This Battlemage-generation GPU operates at a fixed 2670 MHz for both base and boost clocks, which is a notably high sustained frequency. The memory subsystem pairs 12 GB of GDDR6 on a 192-bit interface with 456.0 GB/s of bandwidth, driven by a 2375 MHz memory clock. The GPU's 2560 shading units, 160 texture mapping units, and 80 raster operation pipelines translate to a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s.

In Doom, a fast-paced FPS that emphasizes high frame rates, the GPU's raw throughput becomes the dominant factor at higher resolutions. The 13.67 TFLOPS of FP32 compute is substantial for a card in this segment, and the 20 ray tracing cores provide additional geometry processing capability, though Doom's traditional rasterization workload leans more on the TMUs and ROPs. The 12 GB frame buffer is generous for this title, meaning VRAM capacity is unlikely to be a limiting constraint even at 4K with Ultra settings. The data confirms this: at 3840x2160 Ultra, the combo still produces 37.1 FPS, which suggests the GPU is managing memory allocations without significant spillover.

The GPU's benchmark standing reinforces its mid-range positioning. With an average benchmark score of 23021, the Arc B580 sits at the 66th percentile of all GPUs. Its nearest rival, the AMD Radeon 760M, scores 22999, a delta of just 0.1%. The NVIDIA GeForce RTX 4060 scores 23181, which is 0.7% higher. These figures indicate that the B580 is not a performance outlier; it lands squarely in the established mid-range tier. In Doom, the measured FPS shows the GPU scaling cleanly with settings changes, and the 456.0 GB/s bandwidth proves sufficient to feed the shading units at all tested configurations.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake-S generation, built on Intel's 10 nm process with a 163 mm² die. It runs at a 2.50 GHz base clock with a 4.40 GHz boost clock, and its 65 W TDP reflects a power-efficient design rather than a high-frequency specialist. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. This configuration supports DDR4 and DDR5 memory in dual-channel mode, and the CPU connects via PCIe Gen 5 with 16 lanes.

For a game like Doom, which can scale across multiple threads but still relies heavily on single-thread responsiveness, the i5-12400's balance of core count and clock speed is critical. The Cinebench R23 results show a multi-core score of 15935 and a single-core score of 2249. In the 3DMark suite, the single-thread score is 910, while the max-thread score reaches 5890. The Passmark single-thread score of 3456 and multithread score of 18747 further characterize the processor. The data indicates the CPU can feed the GPU effectively at lower resolutions where frame rates are highest.

The CPU's aggregate performance places it at the 77th percentile of all CPUs, with an average benchmark score of 19850. Its nearest rivals are tightly clustered: the Intel Core i7-9700 scores 19831 (0.1% lower), the Intel Core i7-8700 scores 19894 (0.2% higher), the AMD Ryzen Threadripper PRO 5995WX scores 19928 (0.4% higher), and the Intel Core i5-11600K scores 19771 (0.4% lower). This clustering means the i5-12400 provides essentially identical CPU-bound performance to several older and newer designs, and in Doom, the 6-core/12-thread layout is more than adequate to avoid bottlenecking the Arc B580 at most settings.

Measured FPS Breakdown

At 1920x1080, the Intel Core i5-12400 with the Intel Arc B580 delivers its highest frame rates. On Low settings, the average FPS is 183.1, which is exceptionally smooth for a competitive FPS. Medium settings drop this to 157.6 FPS, and High settings further reduce it to 135.6 FPS. The most demanding 1080p configuration, Ultra, still maintains an average of 108.8 FPS. The scaling from Low to Ultra shows a total drop of 74.3 FPS, indicating that each settings tier imposes a meaningful but manageable load increase on the GPU.

Moving to 2560x1440, the frame rates remain strong but show the expected resolution penalty. Low settings produce 120.6 FPS, which is still above the 120 FPS threshold for high-refresh displays. Medium settings average 106.2 FPS, while High settings drop to 90.1 FPS. The Ultra preset at 1440p yields 72.5 FPS, which remains playable but begins to show the GPU working harder. The delta between Low and Ultra at this resolution is 48.1 FPS, a smaller absolute gap than at 1080p, suggesting the GPU is becoming the primary constraint.

At 3840x2160, the frame rates fall into a range that prioritizes visual fidelity over refresh rate. Low settings average 63.8 FPS, which is still smooth for single-player experiences. Medium settings produce 53.8 FPS, and High settings drop to 46.2 FPS. The Ultra preset at 4K averages 37.1 FPS, which is below the 60 FPS target but remains functional for slower-paced segments of Doom. The resolution scaling from 1080p Low to 4K Low shows a 119.3 FPS reduction, while the same comparison at Ultra shows a 71.7 FPS reduction. This pattern indicates that the GPU's compute and memory bandwidth are the limiting factors at 4K, especially with higher settings.

Resolution Scaling

The measured FPS data reveals a clear and consistent scaling pattern across resolutions. From 1920x1080 to 2560x1440, the average FPS drops by approximately 34-40% depending on the settings preset. For example, at High settings, the FPS falls from 135.6 to 90.1, a reduction of 45.5 FPS. At Low settings, the drop is from 183.1 to 120.6, a reduction of 62.5 FPS. This scaling indicates that the GPU is handling the increased pixel count with proportional efficiency, but the absolute frame rate loss grows larger at lower settings because the starting point is higher.

From 2560x1440 to 3840x2160, the scaling becomes more pronounced. At High settings, FPS drops from 90.1 to 46.2, a 43.9 FPS reduction that represents a 48.7% decrease. At Ultra settings, the drop is from 72.5 to 37.1, a 35.4 FPS reduction. This steeper decline at 4K suggests the GPU is nearing its limits in terms of fill rate and bandwidth. The 456.0 GB/s of bandwidth and 213.6 GPixel/s pixel rate are being taxed heavily at 8.3 million pixels per frame.

The limiting component shifts as resolution increases. At 1080p, the CPU's role is more significant, as evidenced by the high frame rates that approach the processor's capability to issue draw calls. The i5-12400's boost clock of 4.40 GHz and Cinebench R23 single-core score of 2249 indicate it can sustain high instruction throughput, but the 183.1 FPS at Low settings suggests the CPU is near its ceiling. At 1440p and especially 4K, the GPU becomes the clear bottleneck. The Arc B580's 13.67 TFLOPS and 80 ROPs determine the frame rate, and the data shows diminishing returns from settings reductions at 4K: dropping from Ultra to Low only recovers 26.7 FPS at 4K, compared to 74.3 FPS at 1080p. This compression of the settings range at 4K confirms that the GPU is the dominant constraint, and the CPU is fully capable of feeding it at all tested configurations.
