Doom

The Intel Core Ultra 5 245 and NVIDIA GeForce RTX 3080 combination delivers a performance profile in Doom that is heavily dictated by the graphics card, with the CPU providing ample headroom for the game's engine. The data shows a system that excels at high refresh rate 1080p and 1440p gaming, while still maintaining playable frame rates at 4K Ultra settings.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture, built on a 3 nm process by TSMC. It operates with a base clock of 3.50 GHz and a boost clock of 5.10 GHz, which provides the single-thread speed that Doom's engine can utilize. The processor's 24 MB of shared L3 cache and 3 MB per-core L2 cache are relevant for feeding the GPU with draw calls and game state data.

This CPU sits in the 90th percentile of all processors, indicating strong overall performance. Its nearest rivals, based on average benchmark scores, include the AMD Ryzen 7 PRO 5755G and the AMD Ryzen 9 7900, with the Ultra 5 245 trailing them by 0.4% and 0.5% respectively. It is also 0.6% ahead of the Intel Xeon Gold 5318H and 0.8% ahead of the Intel Core i5-14600K in average score. In Cinebench R23, it scores 32924 points in multi-core and 4648 points in single-core, showing that its multi-threaded capability is substantial, even if the game itself may not use all 14 threads.

In the context of Doom, which is a fast-paced FPS that often relies on high IPC and clock speeds, the Ultra 5 245's 5.10 GHz boost clock is a critical asset. The benchmark results imply that the CPU is not the bottleneck in this pairing, as the frame rates scale down significantly when the resolution is reduced, a classic sign of a GPU-limited scenario. The processor's 65 W TDP and support for DDR5 memory with a dual-channel 102.4 GB/s bus contribute to a stable platform, but the gaming outcome is far more dependent on the graphics card. The CPU's Passmark single-thread score of 4394 further corroborates its strength in lightly-threaded workloads typical of game logic and physics.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3080 is the dominant component in this configuration. Built on the Ampere architecture with a GA102 chip, it features 8704 shading units, 272 texture mapping units, and 96 raster output units. The GPU's 10 GB of GDDR6X memory on a 320-bit bus provides a bandwidth of 760.3 GB/s, which is ample for the textures used in Doom at the tested settings. The core clock operates with a base of 1440 MHz and a boost of 1710 MHz, while the memory runs at an effective 19 Gbps.

This GPU is ranked in the 68th percentile of all graphics cards. Its nearest rivals in average benchmark score are surprisingly close, with the NVIDIA P106-100, AMD Radeon Pro Vega 16, AMD Radeon RX 6600M, and AMD Radeon R9 M290X all within 0.4% of its average score of 23172. This suggests that while the RTX 3080 is a capable card, its average synthetic benchmark score is not dramatically higher than those specific older or mobile parts. However, in Doom specifically, the measured FPS data indicates it performs well above the baseline expectations set by its average score.

The GPU's 10 GB of VRAM is a key factor. At 4K resolution with High settings, the card averages 78 FPS, but this drops to 63 FPS at Ultra settings, suggesting that memory capacity and bandwidth are being stressed. The 68 RT cores and 272 tensor cores are present, but Doom does not necessarily leverage ray tracing or DLSS in the measured data. The GPU's pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are the raw throughput numbers that translate directly into fill rate and texture filtering performance, which matter for a game like Doom with its detailed environments. The card's FP32 performance of 29.77 TFLOPS is the theoretical compute ceiling, but the measured frame rates show a more practical picture.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific pairing of the Intel Core Ultra 5 245 and the NVIDIA GeForce RTX 3080 ranks 787th out of 2930 tested combos in Doom. This places it in the top 27% of all configurations, which is a strong result given the age of the GPU and the relative newness of the CPU. The rank indicates that while there are many faster combinations, this system is well above the median performance level for the game.

The ranking is a composite of the CPU and GPU capabilities. Given that the CPU is in the 90th percentile and the GPU is in the 68th percentile, the final rank of 787 is more heavily weighted by the GPU's performance. This makes sense, as the measured FPS data shows the frame rate dropping significantly with increased resolution, pointing to the GPU as the limiting factor. The fact that this combo is not in the top 100 or even top 500 is likely due to many other users pairing newer, higher-end GPUs with similar or better CPUs. However, the rank of 787 out of 2930 still represents a formidable gaming machine for Doom, capable of delivering high refresh rate experiences at lower resolutions.

The delta between the CPU's high percentile and the GPU's lower percentile creates a system where the CPU is waiting on the GPU in many scenarios. This is a common pairing for high-refresh 1440p gaming, where the RTX 3080 is often the bottleneck. The data supports this, as the FPS at 1080p is exceptionally high, but it falls off at 4K, confirming that the GPU is the performance ceiling.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive look at how this combo performs across three resolutions and four settings levels. At 1920x1080, the system is exceptionally fast. With Low settings, it averages 301 FPS. Medium settings drop this to 262 FPS, with a minimum of 223 FPS and a maximum of 301 FPS. High settings yield an average of 221 FPS, and Ultra settings still manage a very high 181 FPS. These numbers indicate that at 1080p, the system is capable of driving high-refresh-rate monitors (240Hz or more) even at Ultra quality.

Moving to 2560x1440, the frame rates remain very strong. Low settings produce an average of 195 FPS. Medium settings average 170 FPS, with a minimum of 144 FPS and a maximum of 195 FPS. High settings see an average of 143 FPS, which is just above the 144Hz refresh rate threshold for many monitors. Ultra settings average 117 FPS, which is still perfectly smooth for most players, though it falls below the 144Hz mark. The drop from 1080p to 1440p is noticeable but not drastic, showing the GPU is still handling the load well.

At 3840x2160, the performance becomes more demanding. Low settings average 105 FPS, which is playable. Medium settings average 92 FPS, with a minimum of 78 FPS and a maximum of 106 FPS. High settings average 78 FPS, which is still smooth for a 60Hz display. Ultra settings drop to 63 FPS, which is just above the 60 FPS target for console-like smoothness. The minimum FPS data for 4K Medium is 78 FPS, indicating that the frame time consistency is good, even when the GPU is under heavy load. The data shows a clear progression: the system is a 1080p and 1440p champion, and a capable 4K performer that requires some settings adjustments to hit the highest refresh rates.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling across resolutions is a textbook example of a GPU-limited system. Moving from 1080p High to 1440p High, the average FPS drops from 221 to 143, a reduction of 35%. Moving from 1440p High to 4K High, the average FPS drops from 143 to 78, a further reduction of 45%. This steep decline in performance as the pixel count increases demonstrates that the rendering workload is the primary bottleneck, not the CPU.

The CPU's role is to prepare frames, and the data suggests it is doing so faster than the GPU can render them. At 1080p, the CPU is likely capable of feeding the GPU well beyond 301 FPS, but the GPU hits its ceiling. The fact that the FPS does not double when the resolution is halved (e.g., from 4K to 1080p) confirms this. If the CPU were the bottleneck, the FPS would remain relatively flat across resolutions. Instead, the FPS scales inversely with pixel count, which is the signature of GPU-bound performance.

The RTX 3080's 10 GB of VRAM is also a factor at 4K. The drop from High (78 FPS) to Ultra (63 FPS) at 4K is a 19% reduction, which could be influenced by the increased memory pressure from higher quality textures and effects. The fact that 4K Low still hits 105 FPS shows that the raw compute power of the GPU is sufficient for the game, but the memory subsystem and fill rate are stressed at higher settings. The conclusion is clear: to get higher frame rates at 4K, one would need a more powerful GPU, as the Intel Core Ultra 5 245 is demonstrably not the limiting factor.
