GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing for Doom, and the data reflects its substantial rendering capabilities. Built on the Ada Lovelace architecture with a 5 nm process, the GPU features 9728 shading units, 304 texture mapping units, and 112 raster output units. The base clock runs at 2205 MHz with a boost clock of 2505 MHz, while memory operates at 1400 MHz with 22.4 Gbps effective speed.

The 16 GB GDDR6X memory pool with 716.8 GB/s bandwidth ensures that even at 4K resolution with Ultra settings, the GPU has ample headroom for texture data and frame buffering. The RTX 4080's 48.74 TFLOPS of FP32 compute power and 761.5 GTexel/s texture rate are directly relevant to Doom's fast-paced rendering demands, where texture throughput and pixel fill rates determine how quickly scenes can be drawn.

The GPU's percentile ranking of 86 means it outperforms 86% of all GPUs in the benchmark database. Its average benchmark score of 54247 places it essentially at parity with the RTX 4080 SUPER (54209, +0.1%) and slightly below the AMD Radeon Pro W5700X (54828, -1.1%). The measured FPS results in Doom show the GPU scaling predictably with resolution: at 1080p, the average FPS across settings ranges from 241 to 363, while at 4K, it drops to a range of 85 to 141. This indicates that the GPU remains the primary driver of performance differences across resolution changes.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best experience. At 3840x2160, Medium settings deliver an average of 123 FPS with a minimum of 104 and maximum of 141, making it the highest-quality preset that maintains a stable frame rate above 100 FPS. High settings at 4K average 104 FPS, which is still playable but offers less headroom for demanding scenes. Ultra at 4K drops to 85 FPS, which may be acceptable for slower gameplay but could feel less responsive in fast action.

At 2560x1440, all settings presets deliver excellent performance. Medium averages 226 FPS (min 192, max 260), High averages 191 FPS, and even Ultra maintains 156 FPS. The data suggests that Ultra at 1440p provides the best visual quality while staying well above typical high-refresh-rate monitor capabilities. At 1920x1080, Medium (345 FPS average, min 294, max 397) and High (295 FPS) both exceed the refresh rate limits of most displays, making the choice between them purely visual preference.

For the best balance of visual fidelity and frame rate stability, Medium settings at 1440p or 4K appear optimal based on the measured rows. At 4K, Medium's minimum FPS of 104 ensures consistent performance without drops below 100 FPS, while at 1440p, Medium's 226 average with a 192 minimum provides substantial headroom. The Low preset at any resolution offers diminishing returns since even Ultra settings remain highly playable at 1080p and 1440p.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates. Low settings average 363 FPS, Medium averages 345 FPS (minimum 294, maximum 397), High averages 295 FPS, and Ultra averages 241 FPS. The step from Low to Medium costs only 18 FPS on average, while the step from Medium to High costs 50 FPS, and High to Ultra costs another 54 FPS. This progression shows diminishing returns as settings increase, with the gap between presets growing larger at higher quality levels.

At 2560x1440, the performance remains strong but begins to show resolution scaling. Low averages 260 FPS, Medium averages 226 FPS (minimum 192, maximum 260), High averages 191 FPS, and Ultra averages 156 FPS. The differences between presets are relatively consistent: Low to Medium is 34 FPS, Medium to High is 35 FPS, and High to Ultra is 35 FPS. The minimum FPS at Medium (192) stays above 190, indicating stable performance even in demanding scenes.

At 3840x2160, the frame rates drop more significantly. Low averages 141 FPS, Medium averages 123 FPS (minimum 104, maximum 141), High averages 104 FPS, and Ultra averages 85 FPS. The gap between Low and Medium is 18 FPS, Medium to High is 19 FPS, and High to Ultra is 19 FPS. The minimum FPS at Medium (104) matches the average at High (104), showing that Medium provides more consistent performance than High at this resolution.

How This Combo Ranks

This combination of Intel Core i5-12400 and NVIDIA GeForce RTX 4080 ranks 298th out of 3712 tested combos in Doom, placing it in the top 8.0% of all systems tested. This ranking reflects the strong performance of both components, though the GPU's high percentile (86) compared to the CPU's (72) suggests the graphics card carries more weight in this title's performance hierarchy.

The CPU's nearest rivals in average benchmark score include the AMD EPYC 7643 (18697, -0.1% relative to the i5), Intel Core i7-1355U (18730, -0.3%), AMD Ryzen AI 5 330 (18811, -0.7%), and Intel Core i3-14100F (18519, +0.9%). These differences are minimal, indicating the i5-12400 sits in a tightly contested performance band among mid-range processors.

The GPU's ranking relative to its nearest rivals shows the RTX 4080 is slightly outpaced by the RTX 4080 SUPER (+0.1%), AMD Radeon Pro W5700X (+1.1%), AMD Radeon RX 6750 GRE 12 GB (+2.6%), and AMD Radeon 8060S (+2.7%). Despite these small deltas, the overall combo rank of 298 demonstrates that this pairing delivers top-tier Doom performance, with only 297 other configurations achieving higher frame rates in the database.

CPU Role

The Intel Core i5-12400 provides the processing foundation for this system. This Alder Lake-S architecture CPU features 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. The 65 W TDP indicates efficient power consumption for a desktop processor. Cache configuration includes 80 KB L1 per core, 1.25 MB L2 per core, and 18 MB shared L3 cache.

In synthetic benchmarks, the i5-12400 shows strong multi-threaded performance relative to its single-thread scores. Cinebench R23 results show 15989 multi-core and 2257 single-core, while Geekbench reports 8564 multi-core and 1848 single-core. The 3DMark scores demonstrate scaling from 910 single-thread to 5890 max-threads, with intermediate results of 1692 (2 threads), 3012 (4 threads), and 4745 (8 threads). This scaling pattern indicates the CPU can effectively utilize its 12 threads in multi-threaded workloads.

For Doom, the CPU's role is primarily in game logic, physics, and draw call processing. The PassMark physics score of 1105 and integer math score of 58366 suggest adequate computational capability for these tasks. The fact that this CPU ranks in the 72nd percentile among all CPUs means it outperforms a majority of processors, though it lags behind the top-tier options. The measured FPS data shows that even at the highest quality settings, frame rates remain high, indicating the CPU is not a bottleneck at any tested configuration.

Resolution Scaling

The measured data reveals how performance scales across resolutions. From 1920x1080 to 2560x1440, average FPS drops by approximately 28-30% across all settings presets: Low drops from 363 to 260 (28.4% decrease), Medium from 345 to 226 (34.5%), High from 295 to 191 (35.3%), and Ultra from 241 to 156 (35.3%). This consistent scaling pattern suggests the GPU is the primary limiting component as resolution increases.

From 2560x1440 to 3840x2160, the FPS drops are more pronounced: Low decreases from 260 to 141 (45.8%), Medium from 226 to 123 (45.6%), High from 191 to 104 (45.5%), and Ultra from 156 to 85 (45.5%). The larger percentage drop at 4K compared to 1440p indicates that pixel fill rate and memory bandwidth become increasingly significant constraints at higher resolutions.

The total scaling from 1080p to 4K shows reductions of 61.2% for Low (363 to 141), 64.3% for Medium (345 to 123), 64.7% for High (295 to 104), and 64.7% for Ultra (241 to 85). This consistent ~60-65% reduction across all settings suggests the scaling is primarily resolution-driven rather than settings-driven. The RTX 4080's 716.8 GB/s memory bandwidth and 280.6 GPixel/s pixel rate are the specifications most relevant to this scaling behavior. Since the CPU performance remains constant across resolutions, the increasing FPS gaps at higher resolutions clearly indicate the GPU becomes the limiting factor as pixel count grows.
