# Doom with Intel Core Ultra 7 270K Plus + NVIDIA GeForce RTX 5070

The Intel Core Ultra 7 270K Plus and NVIDIA GeForce RTX 5070 combination delivers an exceptionally strong experience in Doom, with measured frames per second (FPS) ranging from 71 at 4K Ultra to 335 at 1080p Low. This pairing sits at rank 563 out of 2,930 tested combos for this game, placing it comfortably in the top quintile of all systems evaluated. The data reveals a system where GPU headroom is abundant at lower resolutions, while the CPU's 24 cores and 24 threads provide more than enough compute capacity to feed the RTX 5070's rendering pipeline.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and tells a clear story about which component dominates in Doom. At Medium settings, the average FPS falls from 292 at 1920x1080 to 189 at 2560x1440, then to 102 at 3840x2160. That is a 65% reduction from 1080p to 4K, which strongly indicates the GPU becomes the primary bottleneck as pixel count rises. The scaling pattern is consistent with a game that is heavily GPU-bound at higher resolutions, particularly given the RTX 5070's 12 GB of GDDR7 memory and 192-bit bus width.

Looking at the Ultra preset, the drop is equally pronounced: 202 FPS at 1080p, 131 at 1440p, and 71 at 4K. The 4K Ultra result is the lowest measured value in the entire dataset, which makes sense given that Ultra settings in Doom place maximum load on the GPU. The delta between 1440p and 4K at Ultra is 60 FPS, while the delta between 1080p and 1440p is 71 FPS. This suggests that the scaling penalty accelerates as resolution increases, consistent with the GPU hitting memory bandwidth or shading limits.

At Low settings, the trend holds but with higher absolute numbers: 335 FPS at 1080p, 217 at 1440p, and 118 at 4K. The fact that even Low settings at 4K produce over 100 FPS indicates the RTX 5070 has substantial raw throughput. However, the 118 FPS at 4K Low versus 335 FPS at 1080p Low represents a 64% drop, nearly identical to the Medium setting drop. This consistency across settings suggests resolution scaling is independent of graphical complexity, pointing to fixed GPU resources like ROP count (80) and pixel rate (201.0 GPixel/s) as limiting factors.

The data implies that at 1080p, the CPU may start to constrain performance. The Intel Core Ultra 7 270K Plus, with its 5.50 GHz boost clock, is clearly capable, but the gap between 1080p Low (335 FPS) and 1080p Medium (292 FPS) is only 43 FPS, while the gap between 1440p Low (217 FPS) and Medium (189 FPS) is 28 FPS. The relatively smaller differences at 1080p suggest the CPU is nearing its ceiling, preventing the GPU from fully stretching its legs.

CPU Role

The Intel Core Ultra 7 270K Plus brings 24 cores and 24 threads to the table, a configuration that is overkill for Doom's threading model but ensures the CPU never becomes a bottleneck in most scenarios. The base clock of 3.70 GHz and boost clock of 5.50 GHz provide high single-thread performance, which is critical for older game engines like Doom's id Tech 6. The benchmark data supports this: the CPU's Cinebench R23 single-core score is 2,439, while its multi-core score reaches 44,253, indicating strong performance in both lightly and heavily threaded workloads.

The CPU's role in Doom becomes apparent when examining the FPS scaling at 1080p. At Low settings, the average FPS hits 335, which approaches the practical limit for many display refreshes. However, the gap between Low and Medium at 1080p is 43 FPS, while at 1440p the same gap is 28 FPS. This narrowing suggests that at 1080p, the CPU's per-core performance is beginning to limit frame delivery, as the GPU has more headroom to render frames than the CPU can issue draw calls. The fact that 4K Low still achieves 118 FPS further confirms the CPU is not the primary constraint at higher resolutions.

The 36 MB of shared L3 cache and dual-channel DDR5 memory support with 115.2 GB/s bandwidth provide ample data throughput for Doom's level streaming and texture loading. The CPU's PassMark single-thread score of 5,068 places it in the 96th percentile of all CPUs, meaning it outperforms the vast majority of processors in single-threaded tasks. This is directly relevant to Doom, which relies heavily on a few main threads for game logic and rendering commands. The nearest rival, the Intel Xeon 6520P, shows a 0% deltaPct in average benchmark score, indicating the Core Ultra 7 270K Plus is essentially tied with that server chip in overall CPU benchmarks, though the gaming-relevant single-thread performance is what matters here.

How This Combo Ranks

The combo rank of 563 out of 2,930 tested combinations places this system in the 80.8th percentile of all configs tested for Doom. This is a strong showing, but not a top-tier result, which is interesting given the high-end nature of both components. The rank reflects that Doom is an older title (released in 2016) that does not fully utilize modern hardware, so many combinations with lower-spec parts may achieve similar or better FPS due to the game's optimization.

The RTX 5070's average benchmark score of 40,377 places it in the 82nd percentile of all GPUs, with its nearest rivals including the AMD Radeon Pro 580 (deltaPct 0.1%) and AMD Radeon Pro WX 7100 (deltaPct 0.8%). These are workstation-class GPUs, not gaming-focused parts, which suggests the RTX 5070's gaming performance may be understated by its aggregate benchmark score. The CPU's percentile of 96 is notably higher than the GPU's 82, indicating the CPU is relatively stronger compared to its peers than the GPU is compared to its peers. However, in Doom specifically, the combination still ranks in the top 19% of all systems, showing that both components contribute positively to the gaming experience.

The rank of 563 out of 2,930 also implies that 2,367 other combinations performed better in this game. Given Doom's age and its ability to run well on modest hardware, this is not surprising. The data suggests that for this specific game, the RTX 5070's advanced features like ray tracing cores (48) and tensor cores (192) provide no tangible benefit, as Doom does not utilize these technologies. The raw rasterization performance, measured at 30.87 TFLOPS FP32, is what drives the FPS numbers, and that is substantial enough to secure a top-quintile rank.

Settings Recommendations

For the best experience per the measured rows, the High preset at 1440p offers an excellent balance of visual quality and performance. The average FPS of 160 at 2560x1440 High is well above the 144 Hz refresh rate common on modern monitors, and the jump to Ultra only adds 29 FPS of cost for what is likely a minor visual improvement. At 1080p, High settings deliver 247 FPS, which exceeds even 240 Hz displays, making this the optimal choice for competitive play where frame rate matters most.

For users with 4K displays, Medium settings at 102 FPS provide the best compromise between visual fidelity and smoothness. The 4K Ultra preset drops to 71 FPS, which is still playable but may feel less responsive on high-refresh displays. The 4K High setting at 87 FPS sits between the two, but Medium's 102 FPS offers a 15 FPS advantage over High with presumably minimal visual degradation in this title. The data shows that the scaling from Medium to High at 4K costs 15 FPS, while High to Ultra costs 16 FPS, making the Medium-to-High jump the most efficient upgrade in terms of FPS per setting tier.

At 1080p, the Low preset's 335 FPS is the maximum measured, but Medium at 292 FPS and High at 247 FPS both provide ample headroom for high-refresh gaming. The Ultra preset at 202 FPS is the only 1080p setting that drops below 240 FPS, so users with 240 Hz monitors should stick to High or lower. The 1080p Medium row includes min and max FPS values of 248 and 336, respectively, indicating excellent frame time consistency with no major dips. This makes 1080p Medium a safe recommendation for maximum smoothness.

Measured FPS Breakdown

At 1920x1080, the FPS values span a wide range across settings. Low settings produce an average of 335 FPS, Medium produces 292 FPS (with min 248, max 336), High produces 247 FPS, and Ultra produces 202 FPS. The 133 FPS difference between Low and Ultra at 1080p is the largest across all resolutions, highlighting how much headroom the RTX 5070 has at this resolution. The min and max values for Medium at 1080p (248-336) show that even the lowest frames remain well above 240 FPS, making this a highly consistent experience.

At 2560x1440, the averages are 217 FPS for Low, 189 FPS for Medium (min 161, max 217), 160 FPS for High, and 131 FPS for Ultra. The gap between Low and Ultra narrows to 86 FPS, reflecting the increased GPU load at 1440p. The Medium min of 161 FPS still exceeds 144 Hz displays, meaning even the most demanding scenes at Medium settings will not drop below common high-refresh thresholds. The 1440p data shows a near-linear scaling, with each setting tier costing roughly 28-30 FPS from Low to Medium, Medium to High, and High to Ultra.

At 3840x2160, the averages are 118 FPS for Low, 102 FPS for Medium (min 87, max 118), 87 FPS for High, and 71 FPS for Ultra. The gap between Low and Ultra is now only 47 FPS, the smallest of any resolution. This compression indicates the GPU is becoming the limiting factor, with each setting tier costing roughly 15-16 FPS. The 4K Medium min of 87 FPS ensures that even the lowest frame rates remain above 60 FPS, which is the baseline for smooth gaming. The 4K Ultra result of 71 FPS is the only measured value below 100 FPS at 4K, but it remains comfortably playable.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture with the GB205 chip, manufactured on a 5 nm process at TSMC. With 31,100 million transistors on a 263 mm² die, the GPU offers substantial compute resources: 6,144 shading units, 192 texture mapping units, and 80 raster output units. The boost clock of 2512 MHz drives the FP32 performance to 30.87 TFLOPS, which is the raw compute power that Doom's rasterization pipeline leverages. The texture rate of 482.3 GTexel/s and pixel rate of 201.0 GPixel/s directly impact how quickly the GPU can fill pixels and apply textures, both of which are critical for Doom's fast-paced environments.

The 12 GB of GDDR7 memory on a 192-bit bus provides 672.0 GB/s of bandwidth. In Doom, which was released in 2016 and has modest texture sizes by modern standards, this bandwidth is more than sufficient. The measured FPS data confirms this, as there are no signs of memory-related stutter or sudden FPS drops that would indicate the 12 GB capacity being exceeded. The memory clock of 1750 MHz (28 Gbps effective) is high, but the game's demands do not appear to stress this component significantly.

The GPU's benchmark scores show a mixed picture. The PassMark G3D score of 29,137 and Geekbench OpenCL score of 172,660 indicate strong compute performance, while the 3DMark Steel Nomad DX12 score of 5,077 reflects modern gaming capability. The RTX 5070's percentile of 82 among all GPUs is lower than the CPU's 96, which is notable. The nearest rival, AMD Radeon Pro 580, shows a 0.1% deltaPct in average score, suggesting the RTX 5070's aggregate benchmark performance is closely matched by a much older workstation GPU. However, in Doom specifically, the RTX 5070's combination of high pixel rate and texture rate delivers the excellent FPS numbers seen in the measured data, showing that raw benchmark scores do not always translate directly to real-world game performance.
