GPU Role

The GTX 1660 Ti is a Turing-architecture GPU built on a 12 nm process, featuring 1536 shading units, 96 texture mapping units, and 48 ROPs. Its memory subsystem consists of 6 GB of GDDR6 on a 192-bit bus, delivering a bandwidth of 288.0 GB/s. The GPU’s base clock is 1500 MHz, boosting to 1770 MHz, with a pixel rate of 84.96 GPixel/s and a texture rate of 169.9 GTexel/s. FP32 performance is rated at 5.437 TFLOPS.

In Doom, the data shows that the GPU becomes the primary constraint at higher resolutions and settings. At 3840x2160 Ultra, the average FPS drops to 31, which is the lowest measured value across all rows. The GPU’s 48 ROPs and 6 GB VRAM are sufficient for the game’s textures at 1080p, but at 4K the fill rate and memory bandwidth limit performance. The 288.0 GB/s bandwidth is adequate for 1080p and 1440p, but the 4K Ultra results suggest the GPU cannot maintain the necessary throughput for the game’s demanding effects.

The GTX 1660 Ti’s percentile rank of 41 among all GPUs indicates it sits below the median, aligning with the measured FPS. Its nearest rivals — the AMD Radeon 540 (0.7% lower), AMD Radeon Pro WX 3100 (1.9% lower), AMD Radeon R7 250 (2.2% lower), and Intel Arc A310 (2.3% lower) — all have similar average benchmark scores, so the GTX 1660 Ti is not an outlier in its class. The GPU’s 120 W TDP and single 8-pin power connector suggest a modest power envelope, but the data shows the performance ceiling is dictated by the GPU’s architectural limits rather than power delivery.

Resolution Scaling

The measured FPS data shows a clear scaling pattern from 1080p to 4K. At 1920x1080 with High settings, the average FPS is 109. Moving to 2560x1440 at the same settings, the average drops to 70, a 35.8% reduction. At 3840x2160 High, the average falls to 38, which is 65.1% lower than the 1080p result. This steep decline indicates that the GPU is the limiting component, as the resolution increase directly stresses the pixel fill rate and memory bandwidth.

At Low settings, the scaling is slightly different. The 1080p Low average is 148 FPS, which drops to 96 at 1440p (a 35.1% reduction) and to 52 at 4K (a 64.9% reduction from 1080p). The consistency of these percentage drops across settings suggests the GPU’s rendering workload scales predictably with resolution, independent of the graphical preset. However, the absolute FPS at 4K Low (52) is still below the 1080p Ultra average (89), showing that resolution has a larger impact than settings in this combination.

The Medium settings rows also provide min and max FPS data. At 1080p Medium, the average is 129 with a min of 109 and max of 148. At 1440p Medium, the average is 83 with a min of 71 and max of 96. At 4K Medium, the average is 45 with a min of 38 and max of 52. The min-to-max spread remains proportionally similar across resolutions, indicating that the CPU (Ryzen 9 5950X) is not introducing frame time inconsistencies; the bottleneck is purely GPU-driven. The 4K Ultra result of 31 FPS is the only row below 30 FPS, making 4K Ultra essentially unplayable by typical standards.

Measured FPS Breakdown

At 1920x1080, the data shows the following average FPS by settings: Low at 148, Medium at 129, High at 109, and Ultra at 89. The Medium row also records a min of 109 and max of 148, which exactly matches the Low average, indicating that the Low preset may not be fully utilizing the GPU at 1080p. The gap between Low and Ultra is 59 FPS, a 39.9% reduction, which is substantial but expected given the game’s rendering features.

At 2560x1440, the averages are: Low at 96, Medium at 83, High at 70, and Ultra at 57. The Medium row has a min of 71 and max of 96. The drop from 1080p to 1440p is consistent across settings, with each preset losing roughly 28-35% of its average FPS. The Ultra setting at 1440p produces 57 FPS, which is still playable but sits below the 60 FPS threshold that many users consider smooth.

At 3840x2160, the averages are: Low at 52, Medium at 45, High at 38, and Ultra at 31. The Medium row has a min of 38 and max of 52. The 4K results show that even Low settings cannot reach 60 FPS, and Ultra dips below 32 FPS. The difference between Low and Ultra at 4K is 21 FPS, which is a smaller absolute gap than at lower resolutions, suggesting the GPU is fully saturated regardless of settings.

The measured data includes only average FPS for most rows, with min and max provided solely for Medium settings at each resolution. This limited data still reveals a pattern: the min FPS at 1440p Medium (71) is higher than the average FPS at 4K High (38), indicating a significant performance cliff at 4K. The Ryzen 9 5950X’s capabilities — 16 cores, 32 threads, base clock 3.40 GHz, boost 4.90 GHz — are far beyond what Doom requires, so the FPS variations are attributable to the GTX 1660 Ti’s rendering limits.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture, codenamed Vermeer, manufactured on a 7 nm TSMC process. Its base clock is 3.40 GHz with a boost clock of 4.90 GHz. The CPU has a 64 MB L3 cache, 512 KB L2 per core, and 64 KB L1 per core. Memory support includes DDR4 with dual-channel configuration and 51.2 GB/s bandwidth. The CPU supports PCIe Gen 4 with 20 lanes.

In Doom, the CPU’s role is minimal based on the measured FPS data. The game is a 2016 FPS title that does not scale heavily with core count; the Ryzen 9 5950X’s single-thread performance, as shown by a 3dmark single-thread score of 944 and a Cinebench R23 single-core score of 1614, is more than sufficient. The CPU’s multi-thread capabilities (Cinebench R23 multicore score of 26017) are irrelevant for this game, as Doom typically uses fewer than 8 threads.

The CPU’s percentile rank of 91 among all CPUs indicates it is in the top 10% of processors, yet the combo ranks 3193 out of 3712 in Doom. This disparity confirms that the GTX 1660 Ti is the bottleneck. The nearest CPU rivals — Intel Core Ultra 5 235HX (0.2% lower), AMD EPYC 8124P (0.3% lower), Intel Core i9-13900F (0.4% higher), and Intel Core i7-14700 (0.7% lower) — all have similar average benchmark scores, so swapping the CPU would not change Doom’s FPS meaningfully.

The CPU’s 105 W TDP and 8,300 million transistors show it is a high-end desktop part, but the measured FPS data shows no evidence of CPU-induced frame drops. The min FPS values at Medium settings (109 at 1080p, 71 at 1440p, 38 at 4K) are all consistent with GPU-bound scenarios. The Ryzen 9 5950X’s boost clock of 4.90 GHz ensures that even the game’s single-threaded rendering tasks are handled without delay, leaving the GPU as the sole limiting factor.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution. At 1920x1080, the Ultra preset delivers an average of 89 FPS, which is above the 60 FPS threshold and provides the best visual quality without sacrificing smoothness. The High preset at 109 FPS is also viable for users who prefer higher framerates, but Ultra offers a 20 FPS reduction for improved graphics.

At 2560x1440, the High preset yields 70 FPS, which is playable but not ideal for high-refresh-rate monitors. The Medium preset at 83 FPS provides a better balance, with a min of 71 FPS ensuring minimal drops. The Ultra preset at 57 FPS dips below 60, so Medium is the recommended choice for 1440p.

At 3840x2160, no preset achieves 60 FPS. The Low preset averages 52 FPS, which is the highest 4K result, but the Medium preset at 45 FPS offers better visuals with a min of 38 FPS. For users prioritizing smoothness at 4K, Low is the only option above 50 FPS; for those who accept lower framerates, Medium is a reasonable compromise. The Ultra preset at 31 FPS is not recommended due to its sub-35 FPS average.

The data suggests that the GTX 1660 Ti is best paired with 1080p Ultra or 1440p Medium settings for a playable experience. The 1080p Medium preset shows a min of 109 FPS, which is identical to the 1080p High average, indicating that the Medium preset is the most consistent at 1080p. For users with a 144 Hz monitor, the 1080p Low preset at 148 FPS is the only setting that can fully utilize the refresh rate, but the visual trade-off may not be worth it.

How This Combo Ranks

This combo ranks 3193 out of 3712 tested combinations in Doom, placing it in the bottom 14% of all combos. This low rank is directly attributable to the GTX 1660 Ti, which ranks in the 41st percentile among all GPUs. The Ryzen 9 5950X, by contrast, ranks in the 91st percentile among all CPUs, so the pairing of a top-tier CPU with a mid-range GPU creates a significant imbalance.

The combo’s rank is consistent with the GPU’s nearest rival comparisons. The GTX 1660 Ti’s average benchmark score of 7723 is 0.7% higher than the AMD Radeon 540, 1.9% higher than the AMD Radeon Pro WX 3100, 2.2% higher than the AMD Radeon R7 250, and 2.3% higher than the Intel Arc A310. These small deltas mean that any of these GPUs would likely produce similar Doom performance, so the combo rank would not change dramatically with a different GPU in the same class.

The Ryzen 9 5950X’s nearest rivals have average benchmark scores within 0.7% of its own, meaning the CPU’s performance is not a differentiator in this combo. The 3dmark max-thread score of 11597 and Cinebench R23 multicore score of 26017 show the CPU’s strength, but Doom does not exploit it. The combo’s rank of 3193 indicates that for this specific game, the GPU is the sole determinant of the score, and users seeking better Doom performance should focus on GPU upgrades rather than CPU changes.

The measured FPS data aligns with the rank: the highest average FPS (148 at 1080p Low) is decent, but the 4K results (31-52 FPS) drag the overall experience down. The combo’s rank of 3193 out of 3712 suggests that while it is not the worst combination, it is far from competitive for a demanding title like Doom at high resolutions. For 1080p gaming, the combo is adequate, but for 1440p or 4K, the GTX 1660 Ti is the clear limiting factor.
