The measured frame rates, which reach 184 FPS at 1080p Ultra, demonstrate that this hardware is not bottlenecked by the game’s engine, which confirms both the CPU’s single-threaded prowess and the GPU’s massive compute resources.

GPU Role

The NVIDIA GeForce RTX 4090 is the primary driver of Thief’s visual output, equipped with 24 GB of GDDR6X memory on a 384-bit bus, yielding a bandwidth of 1.01 TB/s. This memory configuration is overkill for a 2014 title, ensuring that texture streaming and high-resolution assets never cause stutters. The GPU’s base clock of 2235 MHz and boost clock of 2520 MHz, combined with 16384 shading units, provide the raw compute needed to push frame rates beyond 200 FPS at lower settings.

The RTX 4090’s performance in Thief is characterized by its ability to maintain high average frame rates even at 4K. At 3840x2160 with High settings, the card averages 84 FPS, which is smooth for a title of this era. The GPU’s 128 RT cores and 512 tensor cores are largely irrelevant for Thief, as the game does not utilize ray tracing or DLSS, but the sheer rasterization power of the 82.58 TFLOPS FP32 unit ensures that the game’s DirectX 11 and 12 pathways are fully saturated.

The GPU’s 176 ROPs and 512 TMUs are critical for pixel fill and texture filtering, which Thief relies heavily on given its detailed environments. At 1440p Medium, the card achieves 182 FPS, showing that the GPU is not the limiting factor at lower resolutions. The 24 GB frame buffer ensures that even the most demanding Ultra settings at 4K, which may exceed 8 GB of VRAM, are handled with ease, preventing any memory-related dips.

Compared to its nearest rivals, the RTX 4090’s average benchmark score of 60347 is nearly identical to the Intel Arc Pro A60 (60326), but the real-world gaming performance is vastly different due to driver maturity and architectural efficiency. The GPU’s 88th percentile ranking among all GPUs highlights its standing, though the nearest rivals in the benchmark list are professional cards, not gaming-focused ones. For Thief, the RTX 4090’s dominance is clear, as it delivers 145 FPS at 4K Low settings, a figure that many GPUs cannot reach at 1080p.

Resolution Scaling

The measured data reveals a predictable scaling pattern as resolution increases, with the RTX 4090 maintaining playable frame rates even at 4K Ultra. At 1920x1080, the average FPS across all settings ranges from 184 (Ultra) to 228 (Low), indicating that the CPU is beginning to limit performance at this resolution. The gap between Low and Ultra at 1080p is 44 FPS, which is significant but not as large as the jump from 1080p to 1440p, suggesting that the GPU still has headroom.

Moving to 2560x1440, the average FPS drops by roughly 15-24% depending on settings. For instance, High settings fall from 187 FPS at 1080p to 143 FPS at 1440p, a 23.5% decrease. This indicates that the GPU is becoming more of a factor, but the CPU’s 12 cores and 5.50 GHz boost clock still provide enough throughput to keep frame rates above 136 FPS even at Ultra. The 1440p Medium setting shows the largest min/max spread (155-209 FPS), suggesting that the scene complexity can cause fluctuations, but the average of 182 FPS remains excellent.

At 3840x2160, the scaling becomes more pronounced, with High settings dropping to 84 FPS from 143 FPS at 1440p, a 41.3% reduction. This steep decline is characteristic of a GPU-bound scenario, where the RTX 4090’s 1.01 TB/s bandwidth is fully utilized. The 4K Low setting achieves 145 FPS, which is impressive for a 4K resolution, but the Ultra setting falls to 80 FPS, indicating that the GPU’s pixel throughput is the limiting factor. The data points to a system where the CPU is the bottleneck at 1080p, but the GPU takes over as the resolution increases, which is the expected behavior for such a high-end pairing.

The 4K Medium setting, with an average of 110 FPS and a min of 94 FPS, demonstrates that the combination can handle 4K with minor dips in demanding scenes. The scaling from 1080p to 4K for Medium settings shows a 46.6% reduction (206 to 110 FPS), which is consistent with the GPU’s workload increasing by approximately 4 times the pixel count. This analysis confirms that the RTX 4090 is the dominant component at 4K, while the Ryzen 9 9900X3D ensures that 1080p and 1440p frame rates are not artificially capped.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this hardware depend on the target resolution and refresh rate. At 1920x1080, Ultra settings provide an average of 184 FPS, which is more than sufficient for any high-refresh-rate monitor (up to 240 Hz). The difference between Ultra and High at 1080p is only 3 FPS (184 vs 187), so there is no practical reason to lower settings from Ultra. Low settings at 1080p achieve 228 FPS, but this sacrifices visual fidelity for a marginal gain, which is unnecessary given the hardware’s capability.

For 2560x1440, Ultra settings average 136 FPS, which is still excellent for most gamers. The Medium preset offers 182 FPS, but the visual jump to High (143 FPS) or Ultra (136 FPS) is worth the frame rate trade-off for a better experience. The data shows that High at 1440p delivers 143 FPS, which is a 5.1% drop from Medium but provides significantly better shadows and textures. Given that the min FPS for Medium is 155, the system never dips below 136 FPS at Ultra, making Ultra the recommended choice for 1440p gaming.

At 3840x2160, the choice is more nuanced. Ultra averages 80 FPS, which is playable but not ideal for competitive play. High settings at 4K achieve 84 FPS, a modest improvement, but Medium offers a substantial jump to 110 FPS with a min of 94 FPS. For a 60 Hz 4K display, Ultra is perfectly suitable, but for 120 Hz+ panels, Medium is the best balance of visual quality and performance. Low settings at 4K (145 FPS) are not recommended, as the visual downgrade is severe for a 31% FPS increase over Medium.

The recommendation is to prioritize Ultra at 1080p and 1440p, while at 4K, Medium provides the best experience per the measured rows. The data indicates that the RTX 4090 has enough headroom to run High at 4K, but Medium ensures frame times stay consistently above 94 FPS, which is crucial for smooth gameplay in a stealth title where quick reactions matter.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across resolutions and settings. At 1920x1080, the system achieves the following average frame rates: Low (228 FPS), Medium (206 FPS), High (187 FPS), and Ultra (184 FPS). The Medium setting has a documented min of 175 FPS and max of 237 FPS, showing a 62 FPS variance that indicates scenes with heavy lighting effects can cause fluctuations. The gap between Low and Ultra is 44 FPS, which is relatively small, confirming that the CPU is the primary limiter at this resolution.

At 2560x1440, the average frame rates are: Low (201 FPS), Medium (182 FPS), High (143 FPS), and Ultra (136 FPS). The Medium setting shows a min of 155 FPS and max of 209 FPS, a 54 FPS spread. The drop from Low to Medium is 19 FPS, but the drop from Medium to High is 39 FPS, indicating that the High preset introduces significant GPU workload increases. Ultra is only 7 FPS lower than High, suggesting that the Ultra preset’s additional effects have diminishing returns in Thief.

At 3840x2160, the average frame rates are: Low (145 FPS), Medium (110 FPS), High (84 FPS), and Ultra (80 FPS). The Medium setting has a min of 94 FPS and max of 127 FPS, a 33 FPS variance. The scaling from Low to Medium is a 24.1% reduction, while Medium to High is a 23.6% reduction, and High to Ultra is a 4.8% reduction. This pattern shows that the GPU’s pixel shading becomes the bottleneck at 4K, with each preset step adding more overhead. The data also reveals that the 4K Low setting outperforms the 1440p Ultra setting by 9 FPS, highlighting the GPU’s raw power.

The complete breakdown shows that the combination is capable of exceeding 200 FPS at 1080p Low and 1440p Low, making it ideal for esports-style play. However, for a game like Thief, which is a single-player stealth title, the focus should be on High or Ultra settings to fully appreciate the atmospheric lighting and shadow effects. The measured FPS values indicate that the system never drops below 80 FPS at any resolution or setting, ensuring a consistently smooth experience.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge, with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. This CPU features 128 MB of L3 cache, which is crucial for gaming performance, as Thief benefits from large caches to store frequently accessed game data. The processor’s 80 KB L1 and 1 MB L2 per core further reduce memory latency, ensuring that the game’s AI and physics calculations are processed without delays.

In Thief, the CPU’s role is most evident at 1080p, where the frame rates are limited by the processor’s single-threaded performance. The 3DMark single-thread score of 1269 and Cinebench R23 single-core score of 6739 indicate that the CPU has exceptional per-core performance, which is essential for a game that may not fully utilize all 12 cores. The 3DMark 16-thread score of 12490 shows that multi-threaded workloads are handled well, but Thief’s engine, released in 2014, likely relies on fewer threads, making the boost clock of 5.50 GHz more critical.

The CPU’s 91st percentile ranking among all CPUs, with an average benchmark score of 54762, places it slightly below the Intel Core Ultra 5 245KF (55093, -0.6%) but above the Intel Core i7-14700F (53620, 2.1%). This proximity in synthetic benchmarks does not translate to identical gaming performance, as the 9900X3D’s 3D V-Cache provides a significant advantage in gaming workloads. The PassMark multi-thread score of 56154 and single-thread score of 4646 confirm that the CPU is a top-tier performer, but the measured FPS data shows that it is not the limiting factor at 4K.

At 4K Ultra, the CPU’s utilization likely decreases as the GPU becomes the bottleneck, but the 9900X3D ensures that frame times are stable, preventing micro-stutters. The 24 threads may be overkill for Thief, but the high boost clock and large cache ensure that the game’s main thread runs at peak efficiency. The CPU’s memory bandwidth of 89.6 GB/s, paired with DDR5 support, ensures that data transfer between the CPU and GPU is not a bottleneck, even at high resolutions.
