GPU Role

The NVIDIA GeForce RTX 4080 drives the frame delivery in this title. The GPU uses the AD103 chip on the Ada Lovelace architecture, fabricated on a 5 nm process by TSMC. It carries 16 GB of GDDR6X memory across a 256-bit bus, yielding 716.8 GB/s of bandwidth. This memory configuration is central to handling Thief's larger textures and geometry at high resolutions. The base clock is 2205 MHz with a boost clock of 2505 MHz, and the memory runs at 1400 MHz with 22.4 Gbps effective speed.

The GPU's compute resources are substantial. It has 9728 shading units, 304 texture mapping units, and 112 raster output units. The RT cores number 76 and tensor cores number 304. Pixel rate reaches 280.6 GPixel/s and texture rate reaches 761.5 GTexel/s. FP32 performance is 48.74 TFLOPS. These figures explain why the GPU sustains high frame rates even at 4K resolution. The recorded data shows 76 FPS average at 4K High and 72 FPS at 4K Ultra, indicating that the GPU has enough headroom to keep the game fluid at maximum settings in this resolution.

The GPU's benchmark profile reinforces its position. Its average benchmark score is 54247, and it ranks in the 86th percentile among all GPUs. The closest rival is the NVIDIA GeForce RTX 4080 SUPER with an average score of 54209, a delta of 0.1%. The AMD Radeon Pro W5700X scores 54828, which is 1.1% higher, and the AMD Radeon RX 6750 GRE 12 GB scores 55698, 2.6% higher. The AMD Radeon 8060S scores 55757, 2.7% higher. These deltas are small, showing the RTX 4080 sits tightly within a performance cluster near the top of the database.

At 1080p, the GPU is not the limiting factor. The frame rates range from 137 FPS at Ultra to 170 FPS at Low. The spread between Low and Ultra at 1080p is 33 FPS, which is modest. The GPU has ample capacity to render this game quickly, and the CPU becomes more relevant at lower resolutions. At 4K, the GPU's workload increases significantly, and the data shows frame rates dropping to 72 FPS at Ultra, a 65 FPS drop from the 1080p Ultra result. This pattern is consistent with a GPU-bound scenario at higher resolutions.

CPU Role

The Intel Core i5-12400 provides the processing foundation for this combo. It is a 6-core, 12-thread processor from the Core 12th Gen series, using the Alder Lake architecture on Intel's 10 nm process. The base clock is 2.50 GHz with a boost clock of 4.40 GHz. The L3 cache is 18 MB shared, with 1.25 MB L2 per core and 80 KB L1 per core. It supports DDR4 and DDR5 memory in dual-channel mode, and it uses PCIe Gen 5 with 16 lanes from the CPU.

The CPU's benchmark results show its capability. In Cinebench R23, it scores 15989 multicore and 2257 singlecore. In Geekbench, it scores 8564 multicore and 1848 singlecore. The 3DMark results include 5873 for 16 threads, 3012 for 4 threads, and 910 for single thread. PassMark multithread score is 18747, and PassMark single thread is 3456. The average benchmark score is 18683, placing it in the 72nd percentile among all CPUs.

The nearest rivals in the database show the CPU's position. The AMD EPYC 7643 has an average score of 18697, just 0.1% higher. The Intel Core i7-1355U scores 18730, 0.3% higher. The AMD Ryzen AI 5 330 scores 18811, 0.7% higher. The Intel Core i3-14100F scores 18519, which is 0.9% lower. These are tight margins, indicating the i5-12400 sits in a well-populated performance band.

In Thief, the CPU's role is most visible at lower resolutions. At 1080p Low, the combo reaches 170 FPS average. At 1080p Ultra, it delivers 137 FPS. The gap between Low and Ultra at 1080p is 33 FPS, which suggests the CPU can feed the GPU adequately even when settings are reduced. At 1440p, the Low setting produces 150 FPS and Ultra produces 121 FPS. The scaling from 1080p to 1440p at Low is a 20 FPS drop, and at Ultra it is a 16 FPS drop. This indicates the CPU maintains a strong frame supply as resolution increases.

The CPU's 6 cores and 12 threads are sufficient for this 2014 stealth title. The game's workload does not appear to stress the processor heavily, since frame rates remain high across all tested settings. The recorded data shows no bottleneck at 1080p, where CPU demand is typically highest relative to GPU load.

How This Combo Ranks

The Intel Core i5-12400 with the NVIDIA GeForce RTX 4080 ranks 540th out of 3720 tested combinations for Thief. This places the combo in the top 14.5% of all tested configurations in the database. The rank reflects the balance between a mid-range 12th Gen processor and a high-end Ada Lovelace GPU.

The CPU's percentile is 72 among all CPUs, while the GPU's percentile is 86 among all GPUs. The combo rank of 540 out of 3720 is slightly lower than what the GPU percentile alone would suggest, because the CPU does not match the GPU's tier. The i5-12400's 6 cores and 12 threads are adequate for this game, but the processor's raw throughput, as measured by its average benchmark score of 18683, is not in the same percentile band as the GPU. This creates a mild imbalance, but the game's frame rates remain high because Thief does not demand extreme CPU resources.

Compared to the GPU's nearest rivals, the RTX 4080's performance is closely matched. The RTX 4080 SUPER is 0.1% lower in average score, and the AMD Radeon Pro W5700X is 1.1% higher. The combo rank would shift only slightly if paired with these GPUs, since the deltas are small. The CPU's nearest rivals also show small deltas, with the AMD EPYC 7643 at 0.1% higher and the Intel Core i3-14100F at 0.9% lower. The combination of a CPU in the 72nd percentile and a GPU in the 86th percentile yields a rank that is competitive but not at the very top of the list.

The database records 3720 tested combos for Thief, and a rank of 540 means the majority of tested configurations are slower. The top ranks likely pair higher-tier CPUs with the same or faster GPUs. The i5-12400's 6-core design is a practical choice for this game, and the measured FPS data confirms that it does not hold back the RTX 4080 to a significant degree.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals where the bottleneck shifts. At 1080p Ultra, the combo delivers 137 FPS. At 1440p Ultra, it delivers 121 FPS, a drop of 16 FPS or 11.7%. At 4K Ultra, it delivers 72 FPS, a drop of 49 FPS from 1440p or 40.5% from 1080p. The steep decline from 1440p to 4K indicates the GPU becomes the dominant limiting factor at 4K.

At Low settings, the scaling is different. 1080p Low yields 170 FPS, 1440p Low yields 150 FPS, a drop of 20 FPS or 11.8%. 4K Low yields 126 FPS, a drop of 24 FPS from 1440p or 25.9% from 1080p. The percentage drop from 1440p to 4K at Low is smaller than at Ultra, which suggests the CPU is more involved at Low settings. At 1080p Low, the CPU must feed frames faster, and the 170 FPS result shows it can. At 4K Low, the GPU still has enough headroom to render 126 FPS, indicating the CPU is not a hard limit even at lower settings.

Medium settings show a middle ground. 1080p Medium averages 154 FPS, 1440p Medium averages 136 FPS, and 4K Medium averages 100 FPS. The drop from 1440p to 4K is 36 FPS or 26.5%. High settings show 139 FPS at 1080p, 123 FPS at 1440p, and 76 FPS at 4K. The 1440p to 4K drop is 47 FPS or 38.2%. These numbers confirm that the GPU workload scales heavily with resolution, and the CPU remains capable across all settings.

The limiting component shifts clearly. At 1080p, the CPU and GPU are both engaged, with the GPU able to push past 170 FPS at Low. At 4K, the GPU's rendering load dominates, and frame rates settle between 72 and 126 FPS depending on settings. The data indicates that users prioritizing 4K should focus on GPU settings, while 1080p users may see CPU-related variations in frame delivery.
