# Doom Performance Analysis: Intel Core Ultra 7 270K Plus + NVIDIA GeForce RTX 3070

The measured frame rates for this combination reveal a system that scales predictably across resolutions, with the RTX 3070 emerging as the primary bottleneck at higher settings while the Core Ultra 7 270K Plus demonstrates ample headroom even at 1080p. The data shows a total of twelve measured configurations spanning three resolutions and four quality presets, offering a comprehensive view of how this pairing handles id Software's 2016 FPS title.

Resolution Scaling

The transition from 1080p to 4K produces a dramatic and consistent drop in frame rates across all settings, with the magnitude of that drop revealing where the system's limits lie. At High settings, the average FPS falls from 190 at 1920x1080 to 123 at 2560x1440, representing a 35.3% reduction, and then further to 67 at 3840x2160, a 45.5% reduction from the 1440p figure. This progressive decline indicates that the RTX 3070's rendering pipeline becomes increasingly saturated as pixel count grows.

Low settings show an even steeper relative decline, dropping from 258 FPS at 1080p to 167 FPS at 1440p (a 35.3% loss) and then to 90 FPS at 4K (a 46.1% loss from 1440p). The consistency of these percentage drops across quality presets—roughly 35% from 1080p to 1440p and another 45% from 1440p to 4K—suggests a GPU-bound scenario where resolution scaling follows predictable bandwidth and fill-rate limitations rather than CPU bottlenecks.

Medium settings reinforce this pattern: 225 FPS at 1080p drops to 145 FPS at 1440p (35.6% reduction) and then to 79 FPS at 4K (45.5% reduction). Ultra settings follow suit with 155, 100, and 54 FPS respectively. The near-identical percentage drops across all four presets strongly imply that the limiting component is the GPU's pixel throughput, not the CPU's geometry or draw-call processing capabilities.

At 1080p, the system achieves frame rates well beyond typical display refresh rates—even Ultra settings produce 155 FPS average—which indicates that the Core Ultra 7 270K Plus with its 24 cores and 5.50 GHz boost clock is more than sufficient to feed the RTX 3070 at lower resolutions. The data suggests that players targeting high refresh rates at 1080p will find no meaningful CPU limitation, while 4K gaming at Ultra settings will strain the GPU to its limits.

GPU Role

The RTX 3070's specifications provide context for these measured results. With 8 GB of GDDR6 memory on a 256-bit bus delivering 448.0 GB/s bandwidth, the card has sufficient memory bandwidth for 1080p and 1440p gaming but may face pressure at 4K with higher-quality textures. The 5888 shading units and 96 ROPs, combined with a boost clock of 1725 MHz, deliver a pixel rate of 165.6 GPixel/s and a texture rate of 317.4 GTexel/s—figures that align with the observed frame rates at 4K.

The GPU's 20.31 TFLOPS of FP32 performance and 46 RT cores indicate a card designed for high-throughput rasterization, which matches Doom's Vulkan-based engine demands. At 4K Ultra, the average of 54 FPS suggests the card is operating near its practical ceiling for this title, as the 8 GB VRAM capacity combined with 4K resolution textures likely approaches the memory footprint limits. The measured FPS range at 4K Medium (67 minimum, 91 maximum) shows frame time variability that could indicate occasional memory pressure or shader compilation hitches.

Interestingly, the RTX 3070's nearest rivals in the benchmark database—the AMD Radeon RX 7600 XT (0.7% higher average score), NVIDIA GeForce GTX 690 (1% higher), and AMD Radeon HD 7970M (1.1% higher)—suggest that this GPU sits at a performance tier where small architectural differences translate to meaningful gaming deltas. The GPU's 61st percentile ranking among all GPUs places it solidly in the mid-to-upper tier, though not at the enthusiast level.

The 1750 MHz memory clock (14 Gbps effective) paired with the 256-bit bus creates a balanced memory subsystem that serves the card well at 1440p, where the data shows 123 FPS at High settings. At 4K, the 448.0 GB/s bandwidth becomes a more critical factor, and the observed 67 FPS at High suggests the card is bandwidth-limited rather than compute-limited in this scenario.

Settings Recommendations

Based on the measured data, the optimal balance between visual quality and frame rate depends heavily on the target resolution and display refresh rate. At 1080p, the Medium preset delivers 225 FPS average with a minimum of 191 FPS, making it an excellent choice for high-refresh-rate displays up to 240 Hz. The High preset at 190 FPS average still exceeds most monitors' capabilities while offering improved visual fidelity.

For 1440p, the High preset at 123 FPS average provides smooth gameplay on 120 Hz displays, while the Medium preset at 145 FPS gives additional headroom for 144 Hz panels. The Ultra preset at 100 FPS remains playable but sacrifices the frame rate cushion that competitive players might prefer. The 4K resolution presents a more constrained choice: High at 67 FPS is borderline for 60 Hz displays, Medium at 79 FPS offers a more comfortable margin, and Low at 90 FPS is the only preset that provides truly fluid motion at this resolution.

The data indicates that Ultra settings provide diminishing returns relative to their frame rate cost. At 1080p, dropping from Ultra (155 FPS) to High (190 FPS) yields a 22.6% frame rate increase; at 1440p, the same transition improves from 100 to 123 FPS (23% increase); at 4K, from 54 to 67 FPS (24.1% increase). This consistent ~23% improvement from Ultra to High across all resolutions suggests that the Ultra preset introduces effects that disproportionately burden the GPU without proportional visual benefit.

The Medium preset offers the largest frame rate advantage over Ultra: 45.2% higher at 1080p (225 vs 155), 45% higher at 1440p (145 vs 100), and 46.3% higher at 4K (79 vs 54). For players prioritizing smooth gameplay over maximum visual detail, Medium represents the sweet spot, particularly at 4K where the 79 FPS average with 67 FPS minimum keeps gameplay fluid.

How This Combo Ranks

This combination ranks 1226th out of 2930 tested combos for Doom, placing it in the 58th percentile of all system pairings in the database. This mid-tier ranking reflects the RTX 3070's position as a capable but not top-tier GPU, while the Core Ultra 7 270K Plus's 96th percentile among all CPUs indicates that the processor is not the limiting factor in this pairing.

The combo ranking sits notably below what the CPU alone might suggest, given that the Ultra 7 270K Plus outperforms rivals like the Intel Xeon 6520P (0% delta), AMD EPYC 4564P (-1.5% delta), AMD EPYC 9175F (-1.9% delta), and AMD EPYC 4565P (-2.1% delta) in average benchmark scores. This discrepancy between CPU performance and overall combo ranking in Doom confirms that the RTX 3070 constrains the system's gaming potential, especially at higher resolutions.

The GPU's 61st percentile ranking among all GPUs, with an average benchmark score of 17,208, places it in the same performance class as the RX 7600 XT and GTX 690. For Doom specifically, the 1226th combo ranking suggests that this pairing is better suited to 1080p and 1440p gaming where the CPU's strengths can be fully utilized, rather than 4K where the GPU becomes the clear bottleneck.

CPU Role

The Intel Core Ultra 7 270K Plus provides substantial computational headroom for Doom, with 24 cores and 24 threads running at a base clock of 3.70 GHz and boosting to 5.50 GHz. This Arrow Lake Refresh processor on TSMC's 3 nm process node delivers a Cinebench R23 multi-core score of 44,253 and single-core score of 2,439, indicating strong single-threaded performance that benefits game engines like Doom's id Tech 6.

The CPU's benchmark results show exceptional multi-threaded capability: Cinebench R20 multi-core of 24,461, Cinebench R15 multi-core of 6,656, and a Passmark multi-thread score of 68,574. The Passmark single-thread score of 5,068 (with a duplicate entry at the same value) confirms that the processor's per-core performance is competitive for gaming workloads. The 36 MB of shared L3 cache and 3 MB L2 per core provide ample cache hierarchy for game data.

The 96th percentile ranking among all CPUs places this processor well above the RTX 3070's 61st percentile GPU ranking, creating an imbalance where the CPU is capable of driving frame rates far beyond what the GPU can deliver. This is evidenced by the 1080p Low result of 258 FPS, which likely approaches the engine's render thread limits rather than CPU limitations. The Passmark physics score of 4,064 and data encryption score of 59,097 further demonstrate the CPU's robust compute capabilities.

The CPU's nearest rivals in average benchmark score are all server-class processors—Intel Xeon 6520P (93,786, 0% delta), AMD EPYC 4564P (95,183, -1.5% delta), AMD EPYC 9175F (95,615, -1.9% delta), and AMD EPYC 4565P (95,764, -2.1% delta)—which underscores its workstation-grade performance. For Doom specifically, this means the CPU will never be the limiting factor in any resolution or settings combination tested, as the GPU saturates well before the CPU's capabilities are exhausted.
