Doom

The AMD Ryzen 5 7500F and NVIDIA GeForce GTX 1660 Ti pairing produces a classic bottleneck scenario in Doom, where the GPU is the definitive limiting factor. The data shows that this combination delivers playable frame rates at 1080p and 1440p, but struggles to maintain smooth performance at 4K, particularly at higher quality presets. With an average benchmark score placing the CPU in the 82nd percentile and the GPU in the 55th percentile, the system's overall performance is heavily constrained by the graphics card, a pattern clearly visible in the measured FPS results across all resolutions.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a textbook GPU-bound workload. At 1080p with Ultra settings, the combo achieves 90.5 FPS, which drops to 55.6 FPS at 1440p and further plummets to 34 FPS at 4K. This represents a 62% reduction in frame rate from 1080p to 4K at Ultra settings, indicating that the GTX 1660 Ti is being pushed to its absolute limits as pixel count increases. The gap between Low and Ultra settings also widens dramatically at higher resolutions. At 1080p, the difference between Low (150.8 FPS) and Ultra (90.5 FPS) is 60.3 FPS, while at 4K the same comparison yields only a 15.4 FPS difference (49.4 FPS vs 34 FPS). This convergence suggests that at 4K, the GPU is so saturated that quality settings have diminishing returns on performance. The 1440p results show a more balanced scenario, where the card still has enough headroom to differentiate between presets, with Low hitting 97.9 FPS and Ultra managing 55.6 FPS.

FAQ

Q: What is the best resolution for this combo in Doom?

A: The data indicates 1080p is the optimal resolution, as it is the only tier where all settings presets exceed 90 FPS, with Low reaching 150.8 FPS and Ultra maintaining 90.5 FPS.

Q: How does the GTX 1660 Ti compare to its nearest rivals?

A: The GPU's average benchmark score of 13925 places it 0.4% ahead of the AMD Radeon RX 570X (13871) and 0.8% behind the NVIDIA RTX A2000 Mobile (13821). It also trails the NVIDIA Tesla K10 by 0.7% (14029).

Q: Is the Ryzen 5 7500F holding back performance in this game?

A: No, the CPU data shows it is not a bottleneck. With a boost clock of 5.00 GHz and 6 cores / 12 threads, it scores 22799 in Cinebench R23 multicore, placing it 0.1% behind the Intel Core i7-11850H (24974) and 0.3% ahead of the AMD Ryzen 7 2700X (25057).

Q: Can this system handle 4K gaming in Doom?

A: Barely. The 4K results show 40.1 FPS on High and 34 FPS on Ultra, which are below the 60 FPS threshold for smooth gameplay. Only the Low preset (49.4 FPS) approaches playability, but it still falls short of ideal performance.

Q: What is the FPS difference between Medium and High settings at 1440p?

A: At 1440p, Medium settings deliver 86.8 FPS while High settings achieve 74.2 FPS, representing a 12.6 FPS gap. This suggests that Medium offers a better balance of visual quality and performance at this resolution.

Q: How does the CPU's single-thread performance affect Doom?

A: Doom benefits from strong single-thread performance, and the Ryzen 5 7500F delivers a Geekbench single-core score of 2759 and a 3DMark single-thread score of 974. This ensures the CPU keeps up with the GPU's demands, as evidenced by the consistent GPU-bound scaling patterns.

How This Combo Ranks

This specific combination ranks 1437th out of 1681 tested combos in Doom, placing it in the bottom 15% of all system configurations. This low ranking is primarily attributable to the GTX 1660 Ti, which sits in the 55th percentile of all GPUs, while the Ryzen 5 7500F is a much stronger component in the 82nd percentile. The ranking reflects the GPU's inability to fully utilize the CPU's capabilities at higher resolutions. For context, the GPU's nearest rivals include the AMD Radeon RX 570X, which scores 13871 (0.4% behind), and the NVIDIA Tesla K10 at 14029 (0.7% ahead). The CPU's nearest rival, the Intel Core i7-11850H, scores 24974, just 0.1% behind the Ryzen 5 7500F's 24993 average. This pairing's rank suggests that while the CPU is overqualified for the GPU, the system as a whole is positioned for 1080p gaming rather than high-resolution experiences.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance across all presets. Low settings produce 150.8 FPS, Medium hits 131.8 FPS, High achieves 109.6 FPS, and Ultra maintains 90.5 FPS. These numbers indicate that 1080p is the sweet spot, with even the most demanding preset staying above the 90 FPS threshold. Moving to 2560x1440, the performance drops become more pronounced. Low settings still deliver a solid 97.9 FPS, Medium follows at 86.8 FPS, High manages 74.2 FPS, and Ultra drops to 55.6 FPS. The 1440p results show that while the system can handle the resolution, users will need to compromise on quality settings to maintain high frame rates. At 3840x2160, the GTX 1660 Ti is clearly overwhelmed. Low settings produce 49.4 FPS, Medium reaches 48.1 FPS, High falls to 40.1 FPS, and Ultra bottoms out at 34 FPS. None of these results meet the 60 FPS target, making 4K gaming impractical with this configuration. The scaling from 1080p to 1440p shows an average FPS reduction of approximately 30%, while the jump from 1440p to 4K results in an additional 45% reduction, highlighting the GPU's diminishing capability at higher pixel densities.

CPU Role

The AMD Ryzen 5 7500F, based on the Zen 4 Raphael architecture and manufactured on a 5 nm TSMC process, provides substantial processing power that far exceeds the demands of this GPU pairing. With 6 cores and 12 threads, a base clock of 3.70 GHz, and a boost clock of 5.00 GHz, the CPU demonstrates strong multi-threaded and single-threaded performance. Its Cinebench R23 multicore score of 22799 and single-core score of 3218 place it competitively among its peers, with the nearest rival Intel Core i7-11850H scoring 24974 (0.1% ahead). The CPU's 32 MB of shared L3 cache and 83.2 GB/s memory bandwidth provide ample data throughput for game logic and physics calculations. In Doom, which is known for its Vulkan API support and efficient multi-threading, the 7500F's 12 threads are more than sufficient to feed the GTX 1660 Ti. The benchmark results confirm this, as the FPS scaling across resolutions follows a pattern consistent with GPU limitation rather than CPU bottleneck. The CPU's 3DMark scores, including 6376 for 16 threads and 974 for single-thread, indicate a processor that is capable of handling far more demanding workloads than this GPU can deliver. The fact that the combo ranks 1437th out of 1681 systems, despite the CPU's high percentile ranking, underscores that the GPU is the primary constraint in this configuration.
