Doom

The Intel Core i7-14700F and AMD Radeon RX 6800 XT combination delivers exceptional performance in Doom, with the data showing this pairing ranks in the 602nd position out of 1681 tested combos. This places the system firmly in the upper tier for this title, where the 20-core processor and RDNA 2 graphics card combine to produce frame rates that easily satisfy high-refresh-rate displays at most settings. The benchmark results reveal a system that is well-balanced for this 2016 FPS title, though the scaling patterns expose where each component carries the load.

Resolution Scaling

The measured frame rates show a predictable yet steep decline as resolution increases, with the GPU becoming the dominant bottleneck at higher pixel counts. At 1080p, the system produces 292 FPS on Low settings, which drops to 213 FPS on High — a 27% reduction that indicates the graphics card is already being pushed harder as settings increase. Moving to 1440p, the Low preset yields 185.4 FPS, while High produces 138.4 FPS, showing a similar proportional drop. The most dramatic scaling appears at 4K, where Low settings produce 102.8 FPS but High falls to 77.9 FPS, and Ultra drops to 59.3 FPS.

The scaling pattern from 1080p to 4K reveals that the CPU has ample headroom at lower resolutions. At 1080p Low, the system achieves 292 FPS, but this falls to 102.8 FPS at 4K Low — a reduction of roughly 65%. This steep curve indicates that the RX 6800 XT's rendering throughput is the primary constraint as pixel count rises. The gap between 1440p and 4K is particularly telling: at High settings, 138.4 FPS at 1440p drops to 77.9 FPS at 4K, a 44% decline that far exceeds the pixel-count difference, suggesting memory bandwidth and shader throughput become limiting factors.

The data also shows that the Ultra preset creates an outsized performance penalty at every resolution. At 1080p, Ultra produces 175.3 FPS versus 213 FPS on High — an 18% hit. At 1440p, the gap widens to 20% (110.4 versus 138.4 FPS). At 4K, Ultra falls to 59.3 FPS, which is 24% below the High preset's 77.9 FPS. This escalating penalty indicates that Ultra settings introduce effects that disproportionately tax the GPU's compute resources, making the preset less attractive at higher resolutions.

CPU Role

The Core i7-14700F brings substantial processing power to this pairing, with 20 cores and 28 threads running at a base clock of 2.10 GHz and boost up to 5.40 GHz. The CPU's benchmark scores show it performs in the 94th percentile among all processors, with a Cinebench R23 multi-core score of 35443 and a single-core score of 5003. This places it within 1% of the AMD Ryzen 9 9900X in average benchmark score, trailing by just 0.6%, while sitting 1.2% ahead of the Intel Xeon Phi 7290.

In Doom, the CPU's role is most visible at 1080p where frame rates exceed 200 FPS. The data shows the processor can feed the GPU effectively at these high rates, as the 292 FPS Low result at 1080p demonstrates. The L3 cache of 33 MB shared across the cores helps maintain consistent frame delivery in a fast-paced FPS where draw calls and physics updates occur rapidly. The high single-thread performance, evidenced by a Geekbench single-core score of 2711, ensures that the game's main thread is not a limiting factor.

The CPU's memory support for both DDR4 and DDR5, with a dual-channel bus, provides flexibility for system builders, though the measured frame rates suggest that memory bandwidth is not the bottleneck in this title. The 65 W TDP indicates efficient operation, and the benchmark results show the processor maintaining high performance without thermal constraints affecting frame rates. The PassMark multithread score of 41765 further confirms that the CPU has substantial headroom for background tasks while gaming.

GPU Role

The Radeon RX 6800 XT is the defining component in this system's 4K performance, featuring 16 GB of GDDR6 memory on a 256-bit bus delivering 512.0 GB/s of bandwidth. The GPU's 4608 shading units and 128 ROPs process Doom's geometry efficiently, with a boost clock of 2250 MHz and a game clock of 2015 MHz. The card's compute capability, measured at 20.74 TFLOPS FP32, supports the high frame rates observed at 1440p and 1080p.

The GPU's benchmark scores place it in the 87th percentile among all graphics cards, with a PassMark G3D score of 24980. It sits 0.5% ahead of the Intel Arc A550M and 1.7% behind the NVIDIA RTX A1000, while leading the NVIDIA GeForce RTX 4070 Ti SUPER by 2.6%. This competitive positioning is reflected in the game's measured results, where the card delivers playable frame rates even at 4K Ultra with 59.3 FPS.

The 16 GB VRAM capacity proves sufficient for Doom at all tested settings, as the game's texture requirements at 4K Ultra do not appear to exceed this allocation. The memory clock of 2000 MHz (16 Gbps effective) provides the bandwidth needed for high-resolution textures without causing frame drops. The GPU's RDNA 2 architecture, built on a 7 nm process with 26,800 million transistors, demonstrates efficient power delivery, though the 300 W TDP requires adequate cooling and a suggested 700 W PSU.

Measured FPS Breakdown

At 1080p, the system delivers outstanding performance across all settings. Low settings produce 292 FPS, Medium achieves 251.8 FPS, High reaches 213 FPS, and Ultra maintains 175.3 FPS. These figures indicate that even the most demanding preset provides frame rates well above typical high-refresh-rate monitor capabilities, making the CPU the likely limiter at this resolution.

The 1440p results show a still-strong performance profile. Low settings yield 185.4 FPS, Medium produces 162.7 FPS, High delivers 138.4 FPS, and Ultra maintains 110.4 FPS. The scaling from Low to Ultra represents a 40% reduction, demonstrating that the GPU begins to feel the load at this resolution while still providing excellent playability.

At 4K, the system remains playable but requires setting compromises. Low settings produce 102.8 FPS, Medium achieves 91.1 FPS, High delivers 77.9 FPS, and Ultra falls to 59.3 FPS. The gap between Medium and High at 4K is 13.2 FPS, while the jump from High to Ultra costs 18.6 FPS. These numbers show that 4K gaming is viable, but users targeting 60 FPS should consider High settings as the practical ceiling.

Settings Recommendations

For 4K gaming, the High preset at 3840x2160 provides the best balance, delivering 77.9 FPS — comfortably above the 60 FPS playability threshold. Ultra drops to 59.3 FPS, which may cause noticeable stutter on standard 60 Hz displays. Medium at 91.1 FPS offers additional headroom for those who prioritize frame consistency over visual fidelity.

At 1440p, the Ultra preset is the clear choice for most users, producing 110.4 FPS while maintaining maximum visual quality. This frame rate is sufficient for 100 Hz monitors and provides a smooth experience. Users with 144 Hz displays may prefer High at 138.4 FPS, which offers a 25% performance boost with minimal visual compromise.

For 1080p, the High preset at 213 FPS represents the sweet spot, as the visual difference between High and Ultra is less noticeable at this resolution while the performance gap is significant. Low settings at 292 FPS are only necessary for competitive play on extreme refresh rate displays, where the CPU's 20 cores and 5.40 GHz boost clock can sustain maximum frame delivery. The Medium preset at 251.8 FPS serves as a middle ground for those who want higher frame rates without sacrificing too much visual quality.
