Thief

The AMD Ryzen 5 7400F paired with the Intel Arc B370 produces a very narrow performance envelope in Thief, with every measured preset at 1080p and 1440p landing within a tight band. Benchmark results indicate that the Low preset at 1080p is the only configuration that consistently delivers a fluid experience, achieving an average of 78 FPS. The Medium preset at 1080p is the highest quality setting that remains playable, with an average of 59 FPS and a recorded minimum of 50 FPS. While the High preset at 1080p reaches 45 FPS average, the data suggests that the visual uplift from Medium to High is not worth the 14 FPS drop, especially given that the Ultra preset at 1080p only yields 43 FPS. For the best balance of visual fidelity and frame rate, the Medium preset at 1920x1080 is the recommended starting point, as it is the only setting above Low that maintains a minimum FPS above 45 in the measured data.

GPU Role

The Intel Arc B370 operates as an integrated graphics processor (IGP) with a 25 W TDP, and its performance profile in Thief reflects its position at the 5th percentile versus all GPUs. The GPU’s clock behavior shows a base clock of 300 MHz and a boost clock of 2400 MHz, but the memory subsystem is entirely dependent on the system, with "System Shared" memory size, type, and bandwidth. This shared-memory architecture means the Arc B370’s performance is heavily influenced by the host system’s DDR5 memory, rather than dedicated VRAM.

In practice, the GPU’s 1280 shading units, 40 TMUs, and 20 ROPs are the physical resources that handle Thief’s rendering. The measured frames per second show a clear ceiling: even at the lowest settings, the 4K resolution only achieves 31 FPS, which is below the threshold for smooth gameplay. The GPU’s FP32 throughput of 6.144 TFLOPS and pixel rate of 48.00 GPixel/s are modest figures, and the data confirms that the Arc B370 is the primary constraint in this combo. At 1080p Low, the combo reaches 78 FPS, but the jump to Medium causes an immediate 19 FPS drop to 59 FPS, indicating that the GPU’s fill rate and shading power are saturated quickly as texture quality and effects increase. The GPU’s nearest rivals, such as the ATI Mobility Radeon HD 5570 (with a deltaPct of -0.2) and the ATI Radeon HD 5770 (deltaPct of -0.5), have nearly identical average benchmark scores, confirming that the Arc B370 is operating at a legacy performance tier in this title.

Resolution Scaling

The measured FPS data reveals a steep performance decline as resolution increases, which is characteristic of a GPU-bound scenario. At 1080p Low, the combo averages 78 FPS. Moving to 1440p Low drops the average to 53 FPS, a reduction of 32%. At 4K Low, the average falls to 31 FPS, representing a 60% drop from the 1080p Low figure. This scaling pattern is consistent across all settings: the 1080p Medium average of 59 FPS falls to 41 FPS at 1440p Medium and further to 24 FPS at 4K Medium. The 4K Medium measurement also includes a minimum of 20 FPS and a maximum of 27 FPS, showing that the frame time variance becomes significant at this resolution.

The data strongly suggests that the limiting component is the GPU, not the CPU. The Ryzen 5 7400F, with its 6 cores and 12 threads, is more than capable of feeding the Arc B370; the CPU’s Cinebench R23 multi-core score of 21,765 and single-core score of 3,072 indicate substantial headroom. As resolution increases, the pixel count grows exponentially, and the Arc B370’s fixed shading resources (1280 units) cannot keep pace. The 4K Ultra average of 17 FPS is effectively unplayable, and even 1440p High at 31 FPS is marginal. The only resolution where the combo delivers acceptable performance across all settings is 1080p, where the FPS ranges from 43 (Ultra) to 78 (Low). This pattern indicates that users should target 1080p for any playable settings, and that the GPU’s memory bandwidth being "System Dependent" further penalizes higher resolutions due to increased memory traffic.

FAQ

*Q: What is the best settings preset for this combo in Thief?*

A: The data shows that the Medium preset at 1920x1080 provides the best compromise, with an average of 59 FPS and a minimum of 50 FPS. The Low preset at 1080p is faster (78 FPS), but Medium offers higher visual quality while staying above the 45 FPS threshold that High and Ultra cannot meet.

*Q: Can this combo run Thief at 4K resolution?*

A: No, the measured data indicates that 4K performance is insufficient for smooth gameplay. The highest 4K average is 31 FPS on Low settings, while Medium, High, and Ultra average 24, 18, and 17 FPS respectively, all of which are below playable thresholds.

Q: How does the Intel Arc B370 compare to its nearest rivals in synthetic benchmarks?

A: The Arc B370’s 3DMark Steel Nomad DX12 score is 1,184. Its nearest rival, the ATI Mobility Radeon HD 5570, scores 1,186 (a deltaPct of -0.2%), and the ATI Radeon HD 5770 scores 1,190 (a deltaPct of -0.5%). This places the Arc B370 within a 1% performance band of these older GPUs.

Q: Is the CPU or GPU the bottleneck in this combo?

A: The GPU is the bottleneck. The Ryzen 5 7400F has strong processing power (Cinebench R23 multi-core score of 21,765 and single-core score of 3,072), but the Arc B370’s 5th percentile GPU ranking and the steep FPS drops with resolution scaling indicate that the integrated GPU is the limiting factor.

Q: What is the highest FPS recorded in the measured data?

A: The highest average FPS is 78, achieved at 1920x1080 with the Low settings preset. The only other preset above 60 FPS is 1440p Low at 53 FPS, which falls short of that mark.

*Q: Does the Ultra preset offer any advantage over High in Thief?*

A: At all three resolutions, the Ultra preset performs slightly worse than High. At 1080p, High averages 45 FPS while Ultra averages 43 FPS; at 1440p, High averages 31 FPS versus 29 FPS for Ultra; at 4K, High averages 18 FPS versus 17 FPS for Ultra. The differences are minimal, suggesting Ultra adds little measurable value for this hardware.

How This Combo Ranks

The AMD Ryzen 5 7400F + Intel Arc B370 combination ranks 2,634 out of 2,851 tested combos in Thief, placing it in the bottom 7.6% of all configurations. This ranking is heavily influenced by the GPU’s weak standing; the Arc B370 sits at the 5th percentile versus all GPUs, while the CPU ranks at the 83rd percentile versus all CPUs. The disparity between the components means the combo’s overall rank is dragged down by the graphics side, despite the processor’s relative strength.

In practical terms, this rank indicates that the vast majority of tested combos deliver higher framerates in Thief. The combo’s best measured result, 78 FPS at 1080p Low, is outpaced by most dedicated graphics cards and even many newer integrated solutions. The CPU’s nearest rivals, such as the Intel Core i5-14600T (deltaPct of 0.1%) and the AMD Ryzen 7 PRO 6850H (deltaPct of -0.2%), have nearly identical average benchmark scores, but those CPUs are often paired with more capable GPUs in real-world systems. For this specific pairing, the data shows that the combo is only suited for low-resolution, low-detail gaming, and its rank of 2,634 reflects that limitation. Users seeking higher settings or resolutions would need to consider a different GPU, as the CPU has ample headroom to support a more powerful graphics solution.

CPU Role

The AMD Ryzen 5 7400F provides a robust foundation for this combo, with its 6 cores and 12 threads based on the Zen 4 architecture (Raphael). The CPU operates at a base clock of 3.70 GHz and boosts to 4.70 GHz, with a 65 W TDP. Its cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3, which supports the processor’s strong synthetic performance. In Cinebench R23, the CPU scores 21,765 multi-core and 3,072 single-core, placing it at the 83rd percentile versus all CPUs. Its Passmark multi-thread score of 25,645 and single-thread score of 3,689 further confirm its capability.

In Thief, the CPU’s role is to feed the GPU with draw calls and game logic. Given the Arc B370’s low performance ceiling, the Ryzen 5 7400F is never the bottleneck. The evidence lies in the resolution scaling: if the CPU were limiting, the FPS would remain constant across resolutions, but instead it drops significantly from 1080p to 4K (e.g., from 78 FPS to 31 FPS on Low settings). This indicates that the CPU is delivering frames faster than the GPU can render them. The CPU’s memory bandwidth of 83.2 GB/s (dual-channel DDR5) is also sufficient for the shared-memory GPU, but the "System Dependent" nature of the Arc B370’s memory means that the CPU’s memory controller must handle both game data and framebuffer traffic. Despite this, the CPU’s 5 nm process node and 6,570 million transistors provide enough computational headroom to avoid any CPU-induced stutters, as evidenced by the relatively stable minimum FPS values (e.g., 50 FPS minimum at 1080p Medium). The CPU’s nearest rivals, the Intel Core i5-14600T and Intel Core Ultra 7 155H (both with deltaPct of 0.1% and 0.2% respectively), show that the 7400F is competitive in processing power, but that strength is wasted in this pairing.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo’s capabilities in Thief, covering three resolutions and four settings presets.

At 1920x1080, the combo delivers its best results. The Low preset averages 78 FPS, which is the highest score in the entire dataset. The Medium preset averages 59 FPS with a minimum of 50 FPS and a maximum of 68 FPS, making it the only other preset to maintain a minimum above 45 FPS. The High preset averages 45 FPS, and the Ultra preset averages 43 FPS. The gap between Low and Medium is 19 FPS, while the gap between Medium and High is 14 FPS, and between High and Ultra is a mere 2 FPS.

At 2560x1440, performance drops notably. The Low preset averages 53 FPS, which is 25 FPS lower than its 1080p counterpart. The Medium preset averages 41 FPS with a minimum of 35 FPS and a maximum of 47 FPS. The High preset averages 31 FPS, and the Ultra preset averages 29 FPS. The scaling from 1080p to 1440p shows a consistent reduction of about 32-35% across all presets, indicating a uniform GPU limitation.

At 3840x2160, the combo struggles to maintain playability. The Low preset averages 31 FPS, which is the only 4K result above 30 FPS. The Medium preset averages 24 FPS with a minimum of 20 FPS and a maximum of 27 FPS. The High preset averages 18 FPS, and the Ultra preset averages 17 FPS. The transition from 1440p to 4K results in a further 40-45% drop in average FPS, confirming that the Arc B370 is overwhelmed by the pixel count. Notably, the 4K results show no measurable benefit from the CPU’s strong single-thread performance, as the GPU’s 6.144 TFLOPS FP32 throughput is the hard limit. The data overall shows that the combo is only viable at 1080p with Low or Medium settings, with 1440p Low being a marginal option at 53 FPS. All 4K presets and all Ultra presets are below 45 FPS, making them unsuitable for a smooth experience in Thief.
