Thief

The AMD Ryzen 9 5900X paired with the AMD Radeon RX 9070 delivers a compelling 1080p experience in Thief, but the data reveals a clear transition to GPU-bound performance as resolution climbs. At 1920x1080, the gap between Low and Ultra settings is relatively narrow, with average FPS moving from 167.5 down to 132. This 35.5 FPS spread suggests that even at the highest preset, the CPU has ample headroom to feed the GPU. The 1080p Ultra result of 132 FPS is notably strong, indicating that the combination is not yet fully stretched at this resolution.

Stepping up to 2560x1440, the scaling pattern shifts. The Low preset still delivers 152.3 FPS, but Ultra drops to 90.6 FPS. The delta between these extremes expands to 61.7 FPS, showing that pixel throughput is becoming a more significant factor. High at 1440p produces 96.8 FPS, which is only 6.2 FPS behind Ultra, a sign that the incremental cost of the highest settings is growing. The 4K results confirm the GPU’s dominance. At 3840x2160, Low averages 96 FPS, but Ultra falls to 51.2 FPS. The High preset at 4K yields 56 FPS, while Medium sits at 76.8. The drop from 1440p to 4K at High settings—from 96.8 to 56 FPS—represents a 42.1% reduction, underscoring that the Radeon RX 9070's 16 GB frame buffer and 644.6 GB/s bandwidth are being heavily taxed at the highest pixel counts.

The limiting component is unmistakably the GPU at 4K. The CPU’s 12 cores and 24 threads, with a boost clock of 4.80 GHz, are not the bottleneck at any resolution tested. The 1080p Low result of 167.5 FPS is likely near the engine’s ceiling, but the consistent scaling from Low to Ultra across all resolutions points to the graphics card as the primary constraint beyond 1080p. For a game from 2014, the performance headroom is massive, but the data shows that 4K Ultra is the only configuration where the frame rate dips below the 60 FPS threshold.

CPU Role

The Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, fabricated on a 7 nm process. Its base clock of 3.70 GHz and boost clock of 4.80 GHz provide substantial single-thread throughput, which is critical for Thief’s stealth-driven gameplay loops. In synthetic benchmarks, the CPU scores 3,341 in Cinebench R15 multi-core and 471 in single-core, while Geekbench results show 11,877 multi-core and 2,202 single-core. These figures place the processor in the 90th percentile among all CPUs, with an average benchmark score of 39,453.

Compared to its nearest rivals, the 5900X sits in a tight cluster. It is 0.2% ahead of the AMD EPYC 4245P, 0.9% ahead of the Intel Core i7-13700F, but 0.7% behind the AMD Ryzen 7 PRO 8845HS and 1% behind the Intel Core i7-13700. These sub-1% deltas indicate that the 5900X is effectively at parity with these chips in general compute tasks. For Thief, the benchmark results show that the CPU is not the limiting factor. At 1080p Low, the system reaches 167.5 FPS, and even at 1080p Ultra it maintains 132 FPS. The fact that the 4K Low setting (96 FPS) is nearly identical to the 1440p Ultra setting (90.6 FPS) suggests that the CPU is capable of sustaining high frame rates regardless of resolution, as long as the GPU can keep up.

The processor’s 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are more than adequate for a 2014 title. The 3DMark results, including a max threads score of 10,075 and a single-thread score of 941, reinforce the idea that the 5900X has no trouble feeding the RX 9070. In essence, the CPU role here is to stay out of the way, and the data confirms it does. The bottleneck only appears when the GPU’s rendering load becomes too high, which happens at 4K Ultra.

GPU Role

The AMD Radeon RX 9070 is the star of the show in this pairing, and its specifications explain the scaling behavior observed. Built on the RDNA 4.0 architecture with a Navi 48 chip, the GPU features 3,584 shading units, 224 texture mapping units, and 128 ROPs. Its boost clock of 2520 MHz and game clock of 2070 MHz drive a pixel rate of 322.6 GPixel/s and a texture rate of 564.5 GTexel/s. The 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth, which is critical for high-resolution textures.

In synthetic tests, the RX 9070 posts a 3DMark Steel Nomad DX12 score of 6,290 and a Geekbench Vulkan score of 165,532. Its Passmark G3D score is 25,381, placing it in the 79th percentile among all GPUs. The nearest rivals show a tight grouping: it is 0.2% behind the NVIDIA A2, 0.3% ahead of the Quadro GV100, and 0.7% ahead of the Radeon HD 7970. This clustering is unusual given the RX 9070’s modern architecture, but the Thief results tell a different story.

The GPU’s role becomes evident when comparing resolutions. At 1080p, the jump from Medium (155 FPS) to Ultra (132 FPS) costs 23 FPS, while at 4K the same settings jump costs 25.6 FPS (from 76.8 to 51.2 FPS). The Low preset at 4K (96 FPS) is faster than the High preset at 1440p (96.8 FPS) is close, but the Ultra preset at 4K (51.2 FPS) is the only result below 60 FPS. The 16 GB VRAM is not exhausted in this game, as evidenced by the fact that even the 4K Ultra setting does not show a catastrophic drop—just a steady decline. The 56 FPS at 4K High is playable, but the 51.2 FPS at 4K Ultra indicates the GPU is working at its limit. The RX 9070’s 36.13 TFLOPS FP32 performance is sufficient for a 2014 title, but the pixel fill rate becomes the deciding factor at higher resolutions.

How This Combo Ranks

The combination of the Ryzen 9 5900X and Radeon RX 9070 ranks 480th out of 1,642 tested combos in Thief, placing it in the top 29.2% of all configurations. This is a strong showing, especially considering the age of the game and the modern hardware involved. The rank reflects that while the CPU is in the 90th percentile of all processors and the GPU is in the 79th percentile, the pairing is not optimized for absolute maximum frame rates in this specific title. The 1080p results are excellent—142 FPS at High and 132 FPS at Ultra—but the 4K Ultra result of 51.2 FPS drags the overall ranking down slightly.

Compared to the CPU’s nearest rivals, the 5900X’s performance is essentially a wash. The 0.9% advantage over the Core i7-13700F and the 1% deficit to the Core i7-13700 mean that swapping the CPU would likely yield less than a 1% change in frame rates. The GPU’s rivals are similarly close, with the 0.7% lead over the Radeon HD 7970 being the largest delta. This suggests that the combo’s rank is more dependent on the GPU’s raw throughput than the CPU’s compute power. The data indicates that the 480th rank is respectable but not elite, as the system struggles to maintain 60 FPS at 4K Ultra. At 1440p, the combo is firmly in high-refresh territory, with 90.6 FPS at Ultra and 152.3 FPS at Low, which is where the rank likely gains most of its value.

Settings Recommendations

The measured FPS rows provide a clear hierarchy for the best experience. For players targeting 60 FPS as a baseline, the 4K High preset is the only viable option at that resolution, delivering 56 FPS—just shy of the target but playable. The 4K Medium preset at 76.8 FPS is the sweet spot for 4K, offering a 34.1% improvement over High while maintaining visual fidelity. The 4K Low preset at 96 FPS is the highest frame rate available at this resolution, but it sacrifices too much detail for a stealth game where environmental cues matter.

At 1440p, the Ultra preset at 90.6 FPS is the recommended choice for the best balance of visuals and performance. It is 4.2 FPS slower than High (96.8 FPS) but provides the full graphical experience. The Medium preset at 125.8 FPS is unnecessary unless the player has a 120 Hz display, in which case it offers a significant margin. The Low preset at 152.3 FPS is only for competitive play, which is not typical for a stealth genre.

At 1080p, the Ultra preset at 132 FPS is the clear winner. It is only 10 FPS slower than High (142 FPS) but delivers the maximum visual quality. The Medium preset at 155 FPS and Low at 167.5 FPS are both excessive for a 60 Hz or even 144 Hz monitor, making Ultra the logical choice. The data suggests that the RX 9070 has enough headroom at 1080p to run Ultra without compromise, and the 5900X has no trouble supporting it. For the best overall experience, 1440p Ultra is the recommended target, as it provides near-90 FPS performance while fully utilizing the GPU’s capabilities. At 4K, Medium is the pragmatic pick, as it stays above 75 FPS and avoids the steep drop to 51.2 FPS seen at Ultra.
