Doom

The AMD Ryzen 7 9700F paired with the AMD Radeon RX 7900 XTX delivers exceptional performance in Doom, with the data showing a combination that is heavily GPU-bound at higher resolutions and capable of extreme frame rates at 1080p. The system ranks in the top 12.4% of all tested combos for this title, confirming its status as a high-end pairing, though the performance scaling across resolutions reveals distinct bottlenecks that buyers should understand.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly demonstrates where the bottleneck shifts between the CPU and GPU. At 1920x1080 with Low settings, the combo produces 366 FPS, which drops to 237 FPS at 2560x1440 and further to 128 FPS at 3840x2160. This represents a 65% performance drop from 1080p to 1440p and a 46% drop from 1440p to 4K. The steep decline from 1080p to 1440p suggests that at 1080p, the CPU is the limiting factor, as the GPU cannot stretch its legs fully at such low resolution and settings.

Moving to High settings tells a similar story but with different magnitudes. At 1080p High, the system hits 269 FPS, dropping to 174 FPS at 1440p (a 35% reduction) and then to 94 FPS at 4K (a 46% reduction from 1440p). The percentage drops between 1440p and 4K are nearly identical for Low and High settings (46% vs 46%), which indicates that at these higher resolutions, the GPU is consistently the primary constraint regardless of quality preset.

The Medium settings data provides the most complete picture with min/max FPS values. At 4K Medium, the average is 112 FPS with a minimum of 95 and maximum of 129, showing a 30% spread between min and max. At 1440p Medium, the average rises to 206 FPS with a 176-237 range, and at 1080p Medium, it reaches 319 FPS with a 271-367 range. The min-to-max spread narrows as resolution increases (30% at 4K vs 35% at 1080p), which is counterintuitive but suggests that at 1080p, the CPU introduces more frame time variance.

Ultra settings show the most dramatic scaling. The system delivers 220 FPS at 1080p Ultra, 143 FPS at 1440p Ultra, and only 77 FPS at 4K Ultra. The 4K Ultra result is the only sub-100 FPS figure in the entire dataset, indicating that this is where the RX 7900 XTX finally meets its match in Doom. The scaling from 1080p to 1440p Ultra (a 35% drop) mirrors the High settings pattern, but the 4K Ultra result shows a 46% drop from 1440p, consistent with other presets.

The overall pattern reveals that 1080p performance is CPU-limited, as the Ryzen 7 9700F's 8 cores and 16 threads cap out around 220-366 FPS depending on settings. The GPU becomes the limiting factor starting at 1440p, where the RX 7900 XTX's 24 GB of GDDR6 memory and 960.0 GB/s bandwidth begin to matter more.

How This Combo Ranks

The combination of the Ryzen 7 9700F and RX 7900 XTX ranks 362nd out of 2930 tested combos in Doom, placing it in the 87.6th percentile of all tested systems. This is a strong result, though not at the absolute top tier, which is expected given that the CPU is not the highest-end Ryzen 9 part and the GPU, while powerful, is not the newest generation.

Breaking down the individual components provides context for this rank. The Ryzen 7 9700F has an average benchmark score of 69996 and sits in the 94th percentile against all CPUs. Its nearest rivals in terms of average score are the AMD Ryzen 9 7940HX (69875, 0.2% slower), the Intel Core i7-14700KF (70163, 0.2% faster), the AMD Ryzen 9 7950X (69515, 0.7% slower), and the Intel Core i7-14700K (69355, 0.9% slower). This puts the 9700F in a very tight performance band with several flagship-class parts from the previous generation.

On the GPU side, the RX 7900 XTX has an average benchmark score of 19410 and sits in the 64th percentile against all GPUs. Its nearest rivals are surprising: the NVIDIA GeForce GTX 1060 3 GB (19334, 0.4% slower), the NVIDIA Quadro K5200 (19602, 1% faster), the AMD FirePro D300 (19637, 1.2% faster), and the NVIDIA TITAN Xp (19177, 1.2% slower). These rival scores are averaged across many different workloads, so they do not reflect Doom-specific performance, but they do indicate that the RX 7900 XTX's overall benchmark profile is competitive with a wide range of GPUs.

The combo rank of 362 out of 2930 suggests that while the individual components are strong, the pairing is not perfectly optimized for Doom specifically. The 87.6th percentile ranking means that roughly 12.4% of tested combos outperform this setup in this game, which is a respectable but not dominant position. The high CPU percentile (94th) versus the lower GPU percentile (64th) indicates that the CPU is more of a strength in this pairing than the GPU.

GPU Role

The AMD Radeon RX 7900 XTX is the workhorse of this combo for Doom, and its specifications directly explain the frame rates observed. The GPU features 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. This massive memory allocation is overkill for Doom, which is not a VRAM-heavy title, but it ensures that memory capacity is never a limiting factor at any resolution or settings level.

The clock speeds tell a more nuanced story. The GPU has a base clock of 1929 MHz, a game clock of 2365 MHz, and a boost clock of 2498 MHz. The memory runs at 2500 MHz with 20 Gbps effective speed. These clocks are high but not extreme for the RX 7000 series. The GPU's 6144 shading units, 384 TMUs, and 192 ROPs provide substantial raw compute power, with a pixel rate of 479.6 GPixel/s and a texture rate of 959.2 GTexel/s.

The FP32 performance of 61.39 TFLOPS and FP16 of 122.8 TFLOPS (2:1) are relevant for Doom's rendering pipeline, which uses a mix of compute and traditional rasterization. The 96 ray accelerators are less relevant for this 2016 title, as Doom does not use ray tracing. The GPU's 355 W TDP and dual-slot cooler with 2x 8-pin power connectors indicate a power-hungry card, but the suggested PSU of 750 W is reasonable for most high-end systems.

The benchmark results for the GPU show a Passmark G3D score of 31238 and a Passmark GPU Compute score of 17689. In DirectX 12, the Passmark score is 131, which is notably low compared to DirectX 11 (356) and DirectX 10 (166). This suggests that the RX 7900 XTX may not be fully optimized for DirectX 12 workloads in synthetic benchmarks, but Doom uses the Vulkan API, so these DirectX scores are not directly indicative of game performance.

The GPU's 64th percentile ranking against all GPUs is lower than expected for a flagship card, but this is influenced by the inclusion of many professional and workstation GPUs in the benchmark database. In practical terms for Doom, the RX 7900 XTX delivers 220 FPS at 1080p Ultra, which is far beyond what the fastest displays can show, and 77 FPS at 4K Ultra, which is playable but not silky smooth.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all resolution and settings combinations. At 1920x1080, the combo delivers outstanding results: 366 FPS at Low, 319 FPS at Medium (271-367 min-max), 269 FPS at High, and 220 FPS at Ultra. These figures are all well above the 144 Hz refresh rate of most gaming monitors, meaning that the system is never the limiting factor at 1080p regardless of quality settings.

At 2560x1440, performance remains strong but shows more differentiation between settings. Low settings produce 237 FPS, Medium delivers 206 FPS (176-237 min-max), High achieves 174 FPS, and Ultra drops to 143 FPS. The 1440p Ultra result is still above 140 FPS, which is excellent for high-refresh-rate 1440p gaming. The gap between Low and Ultra at 1440p is 94 FPS, representing a 40% performance penalty for maxing out settings.

At 3840x2160, the system begins to show its limits. Low settings produce 128 FPS, Medium delivers 112 FPS (95-129 min-max), High achieves 94 FPS, and Ultra drops to 77 FPS. The 4K Ultra result is the only configuration that falls below 90 FPS, which may be a concern for players with 4K 120 Hz displays. The 4K Medium result of 112 FPS is the sweet spot for 4K gaming, offering a good balance between visual quality and frame rate.

The min/max data for Medium settings across all resolutions reveals interesting consistency. At 1080p, the spread is 271-367 (a 96 FPS range). At 1440p, it narrows to 176-237 (a 61 FPS range). At 4K, it further narrows to 95-129 (a 34 FPS range). This narrowing at higher resolutions confirms that the GPU becomes the consistent bottleneck at 4K, reducing frame time variance, while the CPU introduces more variability at lower resolutions.

CPU Role

The AMD Ryzen 7 9700F plays a critical supporting role in this combo, particularly at 1080p where it becomes the primary bottleneck. This 8-core, 16-thread processor is built on the Zen 5 architecture (Granite Ridge) using a 4 nm process from TSMC, with a die size of 70.6 mm² containing 8,315 million transistors. It operates at a base clock of 3.80 GHz and can boost up to 5.50 GHz, with a 65 W TDP that makes it power-efficient for a desktop part.

The CPU's cache hierarchy consists of 80 KB L1 per core, 1 MB L2 per core, and 32 MB of shared L3 cache. This configuration is well-suited for gaming workloads, though Doom is not particularly cache-sensitive. The memory support for DDR5 with dual-channel configuration and 89.6 GB/s bandwidth provides ample memory bandwidth for feeding the GPU.

In benchmark tests, the 9700F demonstrates strong performance across various workloads. Its Passmark multi-thread score is 36470, and single-thread is 4691. The integer math score is 120788, floating point math is 77955, and extended instructions score is 33688. Data compression and encryption scores are 421988 and 21488, respectively. The find prime numbers score of 183 and physics score of 2122 are lower, reflecting that these are not CPU-bound tasks in Doom.

The CPU's 94th percentile ranking against all CPUs indicates it is a top-tier processor. Its average benchmark score of 69996 places it in a tight pack with several high-end rivals, all within 0.9% of each other. This means that in CPU-bound scenarios, the 9700F performs virtually identically to the AMD Ryzen 9 7940HX, Intel Core i7-14700KF, AMD Ryzen 9 7950X, and Intel Core i7-14700K.

In Doom specifically, the CPU's impact is most visible at 1080p. The jump from 366 FPS at Low to 220 FPS at Ultra represents a 40% reduction, which is larger than the GPU's workload increase alone would explain. This suggests that at 1080p Low, the CPU is able to feed frames faster than the GPU can render them, but at 1080p Ultra, the GPU becomes more of a factor while the CPU still has headroom. At 1440p and 4K, the CPU's role diminishes as the GPU becomes the clear bottleneck.

The Ryzen 7 9700F's 16 threads are more than adequate for Doom, which is well-optimized for multi-threaded CPUs. The boost clock of 5.50 GHz provides excellent single-thread performance, which is important for the game's main game logic thread. The combination of high IPC from Zen 5 and high clocks ensures that the CPU never holds back the GPU at resolutions above 1080p.
