Thief

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5050 delivers a playable experience in Thief across most modern resolutions, though the demands of 4K require significant settings compromises. The recorded data shows that this combination is firmly capable of exceeding the 60 FPS threshold at 1080p and 1440p with the highest quality presets, while 4K gaming is only viable at the lowest settings. This analysis breaks down the measured performance figures, component roles, and comparable hardware alternatives.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains an average of at least 60 FPS is Low. The database records an average of 66 FPS at this resolution and preset. Pushing to Medium drops the average to 50 FPS, which falls below the 60 FPS playability threshold, while High and Ultra average 38 FPS and 36 FPS respectively. For a locked 60 FPS experience at 4K, Low settings are the only viable option.

At 2560x1440, the situation improves substantially. The Ultra preset, the most demanding option available, achieves an average of 62 FPS, which clears the 60 FPS threshold by a narrow margin. This makes Ultra the best playable setting at this resolution. The High preset averages 65 FPS, Medium averages 85 FPS, and Low averages 105 FPS, all comfortably exceeding the threshold.

At 1920x1080, the system has ample headroom. The Ultra preset averages 90 FPS, making it the best settings choice at this resolution. High averages 95 FPS, Medium averages 107 FPS, and Low reaches 119 FPS. Every preset at 1080p remains well above the 60 FPS threshold, so players can max out the game without concern.

CPU and GPU Roles

The scaling between resolutions and presets in the recorded data reveals how the balance shifts between the Intel Core i5-9400 and the NVIDIA GeForce RTX 5050. At 1080p, the average FPS across presets ranges from 90 to 119, with the Low preset hitting 119 FPS. The relatively narrow spread between Low and Ultra, roughly 29 FPS, suggests that the GPU still has headroom and the CPU is managing the frame delivery effectively at this resolution.

Moving to 2560x1440, the averages drop to a range of 62 to 105 FPS. The gap between Low and Ultra widens to 43 FPS, indicating that the GPU is beginning to take on more of the workload as pixel count increases. The Ultra preset still averages 62 FPS, which shows that the RTX 5050 remains the primary driver of performance at this resolution, with the CPU providing enough throughput to avoid bottlenecking.

At 3840x2160, the GPU becomes the clear limiting factor. The averages range from 36 FPS at Ultra to 66 FPS at Low, a spread of 30 FPS, but the absolute values are much lower across the board. The RTX 5050 is fully saturated at this resolution, and the CPU’s role diminishes significantly. The fact that Low at 4K averages 66 FPS while Medium drops to 50 FPS shows a steep performance cliff driven by GPU fill rate and memory bandwidth constraints, not CPU processing power.

The data indicates that at 1080p and 1440p, the RTX 5050 is the dominant component, with the i5-9400’s six cores proving sufficient for the game’s demands. At 4K, the GPU is unquestionably the bottleneck, as the CPU has little impact on the frame rate differences between presets.

Measured FPS Breakdown

At 1920x1080, the recorded measurements show strong performance across all settings. Low averages 119 FPS, Medium averages 107 FPS with a minimum of 91 FPS and a maximum of 124 FPS, High averages 95 FPS, and Ultra averages 90 FPS. The minimum recorded at Medium, 91 FPS, still sits far above the playability threshold, indicating stable frame delivery even during demanding scenes.

At 2560x1440, performance remains solid but scales down as expected. Low averages 105 FPS, Medium averages 85 FPS with a minimum of 72 FPS and a maximum of 98 FPS, High averages 65 FPS, and Ultra averages 62 FPS. The Ultra average barely clears the 60 FPS threshold, and the Medium minimum of 72 FPS shows that even the lower preset maintains comfortable headroom.

At 3840x2160, the numbers reveal a sharp decline. Low averages 66 FPS, Medium averages 50 FPS with a minimum of 43 FPS and a maximum of 58 FPS, High averages 38 FPS, and Ultra averages 36 FPS. The Medium preset’s maximum of 58 FPS never reaches the 60 FPS threshold, confirming that only Low is playable at this resolution. The gap between Low and Medium, a 16 FPS drop, is the largest single-step decline in the dataset, underscoring the GPU’s limitations at 4K.

Similar Performance Alternatives

The Intel Core i5-9400 sits in a tight performance cluster based on average benchmark scores. The nearest rival is the Intel Core i3-10305, which scores 2264 compared to the i5-9400’s 2254, a delta of -0.4 percent. The Intel Core i7-1068NG7 scores 2259, just 0.2 percent ahead. The Intel Core i7-10710U scores 2248, 0.3 percent behind, and the AMD Ryzen 5 PRO 1500 scores 2246, 0.4 percent behind. These differences are negligible, so users with any of these CPUs should expect near-identical frame rates in Thief when paired with the same GPU.

The NVIDIA GeForce RTX 5050 also has close rivals in the database. The NVIDIA RTX A4000 Mobile scores 21379 versus the RTX 5050’s 21035, a delta of -1.6 percent. The AMD Radeon HD 8970M scores 21237, 1 percent ahead. The AMD Radeon RX Vega M GL scores 21153, 0.6 percent ahead, and the AMD Radeon RX 5600 XT scores 20713, 1.6 percent behind. This places the RTX 5050 in a performance band where any of these GPUs would deliver broadly similar results in Thief, with differences of roughly 1 to 2 percent being within the margin of run-to-run variance.

The combined rank of this CPU and GPU pairing in the game database is 2728 out of 3720 tested combinations, placing it in the lower-middle range of all possible configurations. This rank reflects the CPU’s age and the GPU’s midrange positioning rather than an inability to run Thief specifically.

The Verdict

Yes, this PC can run Thief. The verdict by resolution from the database is clear. At 1920x1080, all four presets, Low, Medium, High, and Ultra, are playable, with the Ultra preset averaging 90 FPS. This is the ideal resolution for this combination, offering maximum visual quality with significant performance headroom.

At 2560x1440, all four presets are also playable. The Ultra preset averages 62 FPS, which clears the 60 FPS threshold, while lower presets provide even higher frame rates. Players who prefer higher refresh rates can drop to Medium for 85 FPS or Low for 105 FPS.

At 3840x2160, only the Low preset is playable, averaging 66 FPS. The Medium preset falls to 50 FPS, and High and Ultra are below 40 FPS. For 4K gaming, players must accept significant visual compromises to maintain smooth gameplay. The system is a capable 1080p and 1440p machine for Thief, but 4K requires the lowest settings.
