Thief

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4070 combination delivers a thoroughly capable Thief experience, with the data showing a clear shift from CPU-bound performance at lower resolutions to GPU-bound performance at higher ones. The benchmark results indicate this pairing is well-balanced for the game, though the exact experience depends heavily on your target resolution and settings.

Resolution Scaling

The measured FPS data reveals a predictable and steep decline as resolution increases, which is the hallmark of a system that transitions from a CPU bottleneck at 1080p to a GPU bottleneck at 4K. At 1080p with High settings, the combo produces 147.1 FPS, a figure that drops to 99.9 FPS at 1440p, a reduction of roughly a third. Pushing further to 4K High yields just 60.1 FPS, which represents a significant 59% drop from the 1080p baseline. This scaling pattern is typical: the CPU has ample headroom at lower resolutions, but as pixel count rises, the GPU becomes the limiting component.

The scaling behavior is more pronounced at higher quality presets. At Low settings, the transition from 1080p to 4K sees FPS fall from 228.1 to 105.6, a 54% reduction. However, at Ultra settings, the drop is steeper in relative terms, going from 140.7 FPS at 1080p down to 58.8 FPS at 4K, a 58% loss. This indicates that the Ultra preset adds a significant GPU workload that the RTX 4070 struggles to sustain at 4K, while the CPU remains largely untaxed. The data suggests that at 1080p and 1440p, the Ryzen 9 9900X is likely the primary driver of performance, especially at lower settings, whereas at 4K, the GeForce RTX 4070’s rendering capabilities dictate the final frame rates.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, built on a 4 nm process. Its base clock of 4.40 GHz and boost clock of 5.60 GHz provide substantial single-threaded throughput, which is crucial for a game like Thief, a stealth title from 2014 that does not heavily utilize multi-threading. The benchmark data for the CPU shows a strong single-core showing with a 3dmark_single_thread score of 1286 and a Geekbench single-core score of 3341. These figures, combined with a Cinebench R23 single-core score of 6555, indicate that the processor has ample power to handle the game's primary game logic and rendering thread without becoming a bottleneck.

At 1080p with Low settings, the combo reaches 228.1 FPS, a figure that suggests the CPU is capable of feeding the GPU at very high frame rates. The processor’s PassMark single-thread score of 4672 further supports this, showing it is well above average for IPC-heavy tasks. Despite having 12 cores, Thief is unlikely to scale well beyond a few threads, so the Ryzen 9 9900X’s high clock speeds are more important than its core count. The CPU’s 64 MB of shared L3 cache and dual-channel DDR5 memory support also help ensure that data is fed to the cores efficiently, reducing potential stutters. Given that the game’s release predates this CPU by a decade, the processor is effectively overkill for this title, ensuring it will not be the limiting factor at any settings or resolution tested.

GPU Role

The NVIDIA GeForce RTX 4070, based on the Ada Lovelace architecture, is a 5 nm GPU with 5888 shading units and 12 GB of GDDR6X memory on a 192-bit bus. Its memory bandwidth of 504.2 GB/s is more than sufficient for Thief’s textures and geometry, even at 4K. The GPU’s boost clock of 2475 MHz helps it maintain high throughput, which is reflected in its 3DMark Steel Nomad score of 3854. However, the data shows that at 4K Ultra settings, the GPU is clearly the limiting component, as average FPS drops to 58.8, just below the 60 FPS threshold.

The performance at 4K High (60.1 FPS) and 4K Medium (77.5 FPS) shows that the RTX 4070 can handle the resolution, but only with some settings compromises. At 1440p, the GPU has more headroom, delivering 99.9 FPS on High and 133.2 FPS on Medium, which suggests that this resolution is the sweet spot for a high-refresh-rate experience. The GPU’s 12 GB of VRAM is ample for Thief, a game from 2014 that was designed for much less memory, so there is no risk of texture swapping or memory-related stutters. The RTX 4070’s raw compute power, evidenced by its FP32 performance of 29.15 TFLOPS, is more than adequate for this older title, and the data shows that at 1080p, the GPU is rarely the bottleneck, as FPS figures exceed 140 on all presets.

How This Combo Ranks

In the comprehensive database of tested combinations, this pairing of the AMD Ryzen 9 9900X with the NVIDIA GeForce RTX 4070 achieves a rank of 206 out of 1642 total combos in Thief. This places it in the top 12.5% of all tested systems, indicating that it is a high-performing configuration for this specific game. The rank reflects the combined strengths of both components, though the data suggests that the GPU’s performance is the more critical factor for this title, given the CPU’s overwhelming power.

Comparing the components to their nearest rivals in synthetic benchmarks provides context. The CPU’s average benchmark score of 54450 is nearly identical to the AMD Ryzen 9 9900X3D, which scores 54681, a negligible delta of -0.4%. It is also very close to the Intel Core i7-14700F, which scores 54097, a delta of 0.7%. This shows that the 9900X is squarely in the top tier of desktop processors. The GPU’s average benchmark score of 37283 is similarly close to the AMD Radeon RX Vega 56, which scores 37507, a delta of -0.6%, and the NVIDIA GeForce RTX 4080 Mobile, which scores 38135, a delta of -2.2%. While these synthetic scores don’t directly translate to in-game performance, they confirm that both components are performing as expected relative to their peers, and the combo’s rank of 206 out of 1642 reflects solid, if not spectacular, gaming results for Thief.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across all settings and resolutions. At 1080p, the combo is exceptionally fast, starting at 228.1 FPS on Low, dropping to 193.4 FPS on Medium, 147.1 FPS on High, and 140.7 FPS on Ultra. The gap between High and Ultra is small (6.4 FPS), suggesting that the Ultra preset’s additional effects are not overly taxing at this resolution.

Moving to 1440p, the frame rates remain high but show a more pronounced scaling. Low settings produce 175.9 FPS, Medium yields 133.2 FPS, High delivers 99.9 FPS, and Ultra drops to 97.5 FPS. The difference between High and Ultra here is only 2.4 FPS, indicating that the GPU is hitting a similar performance ceiling for these two presets at this resolution.

At 4K, the performance is more constrained. Low settings still produce a playable 105.6 FPS, but Medium drops to 77.5 FPS, High falls to 60.1 FPS, and Ultra dips to 58.8 FPS. The data shows that 4K Ultra is the only configuration that fails to reach 60 FPS on average, making it unsuitable for smooth gameplay without additional tweaks. The 4K High setting just barely clears 60 FPS, but is close enough that any demanding scene could cause dips below that threshold.

Settings Recommendations

Based on the measured rows, the optimal experience depends on your display’s native resolution. For 1080p users, the Ultra preset is the clear choice, as it delivers an average of 140.7 FPS, which is more than sufficient for a high-refresh-rate monitor. The slight drop from 147.1 FPS on High is imperceptible, and the visual enhancements of Ultra are worth the small performance cost.

For 1440p, the High preset offers the best balance, providing 99.9 FPS, which is smooth for most players. While Ultra delivers a similar 97.5 FPS, the marginal difference does not justify the extra visual load, and High is the safer choice to prevent any potential frame drops. If you have a 144 Hz or higher refresh rate monitor, dropping to Medium (133.2 FPS) would be a better option to maximize smoothness, but for standard 60-100 Hz displays, High is ideal.

At 4K, the data suggests that Medium settings are the most practical option, yielding 77.5 FPS, which is comfortably above the 60 FPS target. High settings at 60.1 FPS are playable but leave little headroom, while Ultra at 58.8 FPS is below the target and should be avoided. For a locked 60 FPS experience with visual quality, Medium is the recommended preset. If you prefer higher quality and can tolerate occasional dips, High is viable, but the data shows that Medium provides the most consistent performance for 4K gaming with this combo.
