Doom

# How This Combo Ranks

The AMD Ryzen 5 7400F paired with the NVIDIA GeForce GTX 1660 Ti ranks 2512 out of 2930 tested combinations in Doom. That places this combo in the bottom 15% of all tested systems, a position that reflects the GPU's age more than the CPU's capability. The GTX 1660 Ti sits at the 41st percentile among all GPUs, while the Ryzen 5 7400F lands at the 83rd percentile among all CPUs. This imbalance is the defining characteristic of the pairing: a modern, capable processor driving a legacy graphics card.

The gap between the two components becomes clearer when examining their benchmark averages. The CPU's average benchmark score of 32750 places it nearly even with the Intel Core i5-14600T (32707, 0.1% ahead), the Intel Core Ultra 7 155H (32697, 0.2% ahead), and the AMD Ryzen AI 7 PRO 360 (32662, 0.3% ahead). The GPU's average score of 7723 sits just 0.7% above the AMD Radeon 540 (7673) and 1.9% above the AMD Radeon Pro WX 3100 (7580). In Doom specifically, the combo rank suggests that while the CPU has headroom to spare, the GPU becomes the limiting factor at higher resolutions and settings.

What does the data imply for a prospective user? The combo is positioned for 1080p gaming where it can deliver playable frame rates, but it will struggle to maintain smooth performance at 4K with demanding presets. The measured FPS numbers confirm this pattern across all settings. For a game like Doom, which is known for its fast-paced action, the frame rate consistency matters as much as the average—and the data shows that consistency degrades noticeably as resolution increases.

# Resolution Scaling

The FPS progression from 1080p to 4K reveals a system that is clearly GPU-bound. At 1920x1080 with High settings, the combo delivers 109 FPS. Moving to 2560x1440 drops that to 70 FPS, a decrease of 39 FPS. At 3840x2160, the average falls to 38 FPS, which is 71 FPS below the 1080p result. This scaling pattern—roughly a 36% drop from 1080p to 1440p, and another 46% drop from 1440p to 4K—indicates that the GTX 1660 Ti's rendering throughput is the limiting factor.

The same pattern holds across all settings. At Medium, the FPS goes from 129 at 1080p to 83 at 1440p to 45 at 4K. At Low, it goes from 148 to 96 to 52. At Ultra, it goes from 89 to 57 to 31. The consistent proportional drops across settings suggest that the GPU's pixel processing capability, rather than any specific setting, is the bottleneck.

What does this mean for the CPU's role? The Ryzen 5 7400F, with its 6 cores and 12 threads, has ample processing power for Doom's engine. The fact that FPS scales so strongly with resolution—where the GPU's workload increases dramatically—confirms that the CPU is not holding the system back. If the CPU were the constraint, we would expect to see smaller FPS differences between resolutions, as the CPU's workload would remain similar while the GPU's workload changed.

The measured FPS ranges also tell a story. At 1080p Medium, the minimum FPS is 109 and the maximum is 148, a spread of 39 FPS. At 1440p Medium, the spread narrows to 25 FPS (71 to 96). At 4K Medium, the spread is 14 FPS (38 to 52). This tightening of the range at higher resolutions indicates that the GPU is hitting its performance ceiling, reducing the variation that comes from scene complexity.

# Measured FPS Breakdown

1920x1080:

• Low: 148 FPS average
• Medium: 129 FPS average, 109 FPS minimum, 148 FPS maximum
• High: 109 FPS average
• Ultra: 89 FPS average

At 1080p, the combo delivers its strongest performance. Even at Ultra settings, the average stays above 85 FPS, which is respectable for a GPU of this class. The jump from Low to Medium costs 19 FPS, while the jump from Medium to High costs another 20 FPS. The step from High to Ultra costs 20 FPS more. This linear degradation suggests that each preset tier imposes a similar workload increase on the GPU.

2560x1440:

• Low: 96 FPS average
• Medium: 83 FPS average, 71 FPS minimum, 96 FPS maximum
• High: 70 FPS average
• Ultra: 57 FPS average

At 1440p, the system remains playable at all settings, but the margins shrink. The difference between Low and Medium is 13 FPS, between Medium and High is 13 FPS, and between High and Ultra is 13 FPS. The consistency of these gaps mirrors the 1080p pattern, but the absolute values are lower, pushing Ultra below the 60 FPS threshold.

3840x2160:

• Low: 52 FPS average
• Medium: 45 FPS average, 38 FPS minimum, 52 FPS maximum
• High: 38 FPS average
• Ultra: 31 FPS average

At 4K, the combo struggles. Even at Low settings, the average FPS falls below 60. At Ultra, it drops to 31 FPS, which is barely playable for a fast-paced shooter. The minimum at Medium is 38 FPS, indicating that demanding scenes can push the system well below the average.

The data shows a clear trend: the GTX 1660 Ti's 6 GB of GDDR6 memory and 192-bit bus provide enough bandwidth for 1080p and moderate 1440p gaming, but the GPU's raw compute power—5.437 TFLOPS FP32—cannot sustain high frame rates at 4K.

# CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor from the 7000 series, built on the Zen 4 architecture with a 5 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The CPU's cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. This configuration gives the CPU a strong single-threaded presence, as evidenced by its Cinebench R23 single-core score of 3072 and PassMark single-thread score of 3689.

In Doom, the CPU's role is to feed the GPU with draw calls and physics calculations. The game's id Tech 6 engine is known for being well-optimized across multiple threads, and the Ryzen 5 7400F's 12 threads are more than sufficient. The CPU's multi-threaded scores—Cinebench R23 multi-core of 21765 and PassMark multi-thread of 25645—suggest it can handle any CPU-side workload the game throws at it without becoming a bottleneck.

The CPU's percentile ranking of 83 among all CPUs reinforces this assessment. It is a top-tier processor by any measure, competing closely with recent Intel and AMD mobile and desktop parts. Its nearest rival, the Intel Core i5-14600T, has an average score of 32707, just 0.1% behind the Ryzen 5 7400F's 32750. This near-tie indicates that the CPU is not the limiting factor in this combo.

The data supports this conclusion. If the CPU were the bottleneck, we would expect to see FPS plateau across different resolutions, as the CPU's frame production limit would cap performance regardless of GPU workload. Instead, FPS scales inversely with resolution, which is the signature of a GPU-bound system. The CPU's 65 W TDP and DDR5 memory support (with 83.2 GB/s of memory bandwidth) are more than adequate for Doom's requirements.

# Settings Recommendations

For the best experience in Doom with this combo, the data points to 1920x1080 with Medium settings as the optimal configuration. This preset delivers 129 FPS average, with a minimum of 109 FPS and a maximum of 148 FPS. The minimum FPS is well above the 60 FPS threshold, ensuring smooth gameplay even in demanding scenes. The 39 FPS spread between minimum and maximum indicates some scene-to-scene variation, but the floor is high enough to maintain playability.

At 1080p High settings, the average drops to 109 FPS, but the minimum FPS is not listed in the data. The 20 FPS gap between Medium and High suggests that High settings impose a significant additional load on the GPU. For players who prioritize visual fidelity, High settings at 1080p remain a viable option, but Medium offers a larger safety margin.

At 1440p, the best option is Medium settings, which delivers 83 FPS average with a minimum of 71 FPS. This stays above 60 FPS, but the margin is thinner than at 1080p Medium. High settings at 1440p drop to 70 FPS average, and Ultra falls to 57 FPS, which is below the threshold for smooth gameplay. For 1440p users, Medium is the recommended preset.

At 4K, no setting provides a fully smooth experience. Low settings deliver 52 FPS average, Medium 45 FPS, High 38 FPS, and Ultra 31 FPS. Even the lowest preset falls short of 60 FPS, so 4K gaming with this combo requires accepting compromises. The data suggests that 4K is not a practical target for this system in Doom.

The measured FPS ranges reinforce these recommendations. At 1080p Medium, the 109 FPS minimum ensures that even the most intense combat sequences remain fluid. At 1440p Medium, the 71 FPS minimum is acceptable but leaves less headroom. The pattern across resolutions and settings indicates that Medium is the sweet spot for this combo, balancing visual quality with performance.

# GPU Role

The NVIDIA GeForce GTX 1660 Ti is the limiting component in this combo. The GPU is based on the TU116 chip, built on a 12 nm process with 6,600 million transistors. It operates at a base clock of 1500 MHz and a boost clock of 1770 MHz, with 6 GB of GDDR6 memory on a 192-bit bus providing 288.0 GB/s of bandwidth. The GPU's 1536 shading units and 48 ROPs deliver a pixel rate of 84.96 GPixel/s and a texture rate of 169.9 GTexel/s.

The GTX 1660 Ti's 41st percentile ranking among all GPUs reflects its position as a mid-range part from 2019. Its average benchmark score of 7723 places it just ahead of the AMD Radeon 540 (7673, 0.7% behind) and the AMD Radeon Pro WX 3100 (7580, 1.9% behind). In Doom, the GPU's performance is adequate for 1080p but falls off sharply at higher resolutions.

The GPU's memory configuration is particularly relevant for Doom. The 6 GB of GDDR6 memory is sufficient for 1080p and 1440p textures, but at 4K, the game's texture requirements may exceed the available memory, causing the GPU to rely on slower fallback mechanisms. The 288.0 GB/s bandwidth is also a potential constraint at high resolutions, where the GPU must move more pixel data to the framebuffer.

The measured FPS data shows the GPU's performance ceiling. At 1080p, the GPU can sustain 148 FPS at Low settings, but this drops to 89 FPS at Ultra—a 40% reduction. At 4K, the same settings range from 52 FPS at Low to 31 FPS at Ultra—a 40% reduction but at much lower absolute values. This consistent percentage drop suggests that the GPU's compute and memory resources are being taxed uniformly across settings, with the absolute performance level determined by resolution.

The GPU's DirectX 12 score of 51 in PassMark benchmarking is notably low, but Doom's Vulkan support (the GPU supports Vulkan 1.4) may provide better performance than the DirectX 12 path. The GPU's OpenCL score of 51029 and Vulkan score of 5827 in Geekbench indicate that it has reasonable compute capabilities for a card of its class. However, the 5.437 TFLOPS FP32 performance is the fundamental limit that governs Doom's frame rates at higher resolutions.
