How This Combo Ranks

The data places this Intel Core Ultra 5 245 and AMD Radeon RX 6800 XT combination at rank 866 out of 2930 tested combos in Doom. This position places it in the top 30% of all systems tested for this title. The ranking reflects a balanced pairing where the CPU's strong single-threaded performance complements the GPU's high rasterization throughput.

Benchmark results indicate that this combo outperforms roughly 70% of the tested configurations. The percentile rank of the GPU (85th among all GPUs) is notably higher than the combo's overall percentile, suggesting that the GPU is the dominant component in this pairing. Meanwhile, the CPU sits in the 90th percentile among all CPUs, meaning both components are individually above-average performers.

The deltaPct values from the nearest rivals show that the CPU is effectively in a dead heat with its closest competitors—all deltas are within ±0.8%. This means the CPU choice is unlikely to be the differentiating factor in gaming performance. Instead, the GPU's position between the RTX A1000 Mobile and the Arc A550M indicates that the graphics card is the primary driver of frame rates in this title.

GPU Role

The AMD Radeon RX 6800 XT is the workhorse of this pairing for Doom. Its 16 GB of GDDR6 memory on a 256-bit bus provides 512.0 GB/s of bandwidth, which is more than sufficient for the textures and geometry in this 2016 title. The generous memory capacity ensures that even at 4K resolution with High settings, the game does not encounter VRAM limitations.

The GPU's clock behavior is telling: the base clock of 1825 MHz, game clock of 2015 MHz, and boost clock of 2250 MHz represent a substantial overclocking headroom from the factory. The game clock is the relevant figure for sustained gaming loads, and at 2015 MHz, the RDNA 2.0 architecture delivers strong per-clock performance.

With 4608 shading units, 288 TMUs, and 128 ROPs, the RX 6800 XT has the raw compute resources to drive high frame rates. The 20.74 TFLOPS of FP32 performance is a theoretical ceiling that Doom can approach given its well-optimized Vulkan and OpenGL renderers. The 72 ray accelerators are less relevant for this title, but the 12 Ultimate (12_2) DirectX support ensures full feature compatibility.

The GPU's pixel rate of 288.0 GPixel/s and texture rate of 648.0 GTexel/s are critical metrics for fill-rate-bound scenarios. In Doom's fast-paced combat, these rates allow the GPU to maintain high FPS even with multiple enemies and particle effects on screen. The 128 ROPs are particularly important for 4K rendering, where pixel throughput becomes a limiting factor.

Measured FPS Breakdown

The measured FPS data covers four settings presets (Low, Medium, High, Ultra) across three resolutions (1920x1080, 2560x1440, 3840x2160). All measurements are average FPS values, with min and max FPS only recorded for Medium settings.

At 1920x1080, the combo delivers exceptional performance across all presets. Low settings produce 292 FPS average, Medium produces 254 FPS (min 216, max 292), High produces 215 FPS, and Ultra still maintains 176 FPS. These numbers indicate that at 1080p, the system is largely CPU-bound at lower presets—the GPU has enough headroom to render frames faster than the CPU can feed it. The jump from Low to Ultra costs 116 FPS (a 39.7% reduction), showing that the GPU becomes more involved as visual complexity increases.

At 2560x1440, performance remains very strong. Low settings average 189 FPS, Medium averages 165 FPS (min 140, max 189), High averages 139 FPS, and Ultra averages 114 FPS. The progression from Low to Ultra at this resolution shows a 75 FPS drop (39.7% reduction), which is proportionally similar to 1080p. The min FPS of 140 at Medium settings indicates that even in demanding scenes, the system maintains a comfortable frame rate above 144 Hz in most situations.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings average 102 FPS, Medium averages 89 FPS (min 76, max 103), High averages 75 FPS, and Ultra drops to 62 FPS. The difference between Low and Ultra is 40 FPS (39.2% reduction), consistent with the other resolutions. The min FPS of 76 at Medium 4K is still playable, but the Ultra preset's 62 FPS average is approaching the threshold where fast-paced FPS gameplay may feel less fluid.

Settings Recommendations

The measured data suggests that the High preset offers the best balance of visual fidelity and performance across all resolutions. At 4K High, the combo averages 75 FPS, which is above the 60 FPS target for smooth gameplay. At 1440p High, the 139 FPS average comfortably exceeds 120 Hz refresh rates. At 1080p High, 215 FPS is ample for even the highest refresh rate displays.

For competitive play where frame rate is paramount, the Medium preset provides significant headroom. At 1080p Medium, the 254 FPS average with a 216 FPS minimum ensures that even the most intense firefights stay well above 200 FPS. The min FPS data at Medium settings shows consistency: 216 FPS at 1080p, 140 FPS at 1440p, and 76 FPS at 4K. These minimums are notably higher than the average FPS of the Ultra preset at each corresponding resolution.

The Ultra preset is best reserved for 1080p and 1440p gaming where visual quality takes precedence. At 1440p Ultra, the 114 FPS average still provides a smooth experience on 120 Hz displays. At 4K Ultra, the 62 FPS average is borderline—acceptable for slower-paced exploration but potentially problematic during intense combat sequences.

The Low preset is unnecessary for this hardware in Doom. Even at 4K Low, the 102 FPS average is far above what the Ultra preset delivers, and the visual downgrade is substantial. The data indicates that Medium is the lowest preset that makes sense, and High is the recommended default for most users.

CPU Role

The Intel Core Ultra 5 245 plays a supporting but important role in this combo. With 14 cores and 14 threads, it has no hyper-threading, but the 14 physical cores are more than sufficient for Doom's engine. The base clock of 3.50 GHz and boost clock of 5.10 GHz are critical—Doom is a game that benefits from high single-threaded performance, and the 5.10 GHz boost clock provides that.

The CPU's cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. This large L3 cache is beneficial for game workloads that exhibit spatial and temporal locality. The DDR5 memory support with 102.4 GB/s of bandwidth ensures that the CPU can feed data to the GPU without becoming a bottleneck.

The benchmark data shows the CPU's strength in single-threaded tasks: 468 in Cinebench R15 single-core, 1952 in R20, and 4648 in R23. These scores place it in the 90th percentile of all CPUs. The multi-threaded scores (3318 in R15, 13828 in R20, 32924 in R23) are also strong, though Doom's engine primarily relies on a few heavily-optimized threads rather than massive parallelism.

The 14-core count without hyper-threading is an interesting design choice. In Doom, which typically uses 4-8 threads effectively, the remaining cores handle background tasks, streaming, and OS overhead. The lack of hyper-threading means each core has dedicated resources, which can reduce contention in latency-sensitive workloads.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the balance between CPU and GPU limitations. At Low settings, the average FPS drops from 292 at 1080p to 189 at 1440p (35.3% reduction) and then to 102 at 4K (46.0% reduction from 1440p). The total drop from 1080p to 4K at Low settings is 65.1%. This steep decline indicates that even at Low settings, the GPU is becoming the limiting factor as resolution increases.

At Ultra settings, the scaling is more gradual in percentage terms. The average FPS drops from 176 at 1080p to 114 at 1440p (35.2% reduction) and then to 62 at 4K (45.6% reduction from 1440p). The total drop from 1080p to 4K at Ultra is 64.8%. The similar percentage drops across settings presets suggest that the GPU's fill-rate and bandwidth constraints scale consistently with pixel count.

The fact that the FPS does not halve when going from 1440p to 4K (which has roughly 2.25 times the pixels) indicates that the system is not purely pixel-bound. At 1080p, the CPU's single-threaded performance caps the frame rate—the 292 FPS at Low settings is likely near the CPU's practical limit for this game. As resolution increases, the GPU becomes more dominant in determining performance.

The Medium settings data provides the most complete picture with min and max FPS values. At 1080p Medium, the 216-292 FPS range shows a broad spread, suggesting CPU and GPU interplay. At 1440p Medium, the 140-189 FPS range narrows proportionally. At 4K Medium, the 76-103 FPS range shows that the GPU is now firmly in control. The narrowing of the FPS range as resolution increases is a classic sign of the GPU becoming the bottleneck.
