To The Core

The pairing of the Intel Core Ultra 5 225 with the NVIDIA GeForce RTX 5090 produces a fascinating dataset in To The Core, an idle game that clearly scales aggressively with raw frame throughput. The measured results reveal a system that is overwhelmingly GPU-bound at lower resolutions, with the CPU becoming a more relevant factor only as the resolution and settings climb. This analysis breaks down the specific roles of each component, how they interact across the three tested resolutions, and what the final frame rates indicate about the overall system balance.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 5 225 is a 10-core, 10-thread processor based on the Arrow Lake-S architecture, built on a 3 nm process node. Its base clock is 3.30 GHz, boosting up to 4.90 GHz, and it carries a 20 MB shared L3 cache. The processor’s benchmark results place it in the 85th percentile of all CPUs, with an average benchmark score of 36938. In a game like To The Core, which is an idle title, the workload often depends on consistent single-threaded responsiveness alongside the ability to manage background simulation logic.

The data suggests the CPU is not the primary bottleneck in most configurations. At 1080p with Low settings, the system achieves 625 FPS, a figure so high that it likely strains the CPU's ability to feed the GPU. The Ultra 5 225’s single-core performance, as evidenced by a Cinebench R23 single-core score of 3655, provides a strong foundation for this. However, the CPU’s multi-threaded capability, shown by a Cinebench R23 multi-core score of 25891, also plays a part in ensuring the game's background processes do not introduce stutter.

When compared to its nearest rivals, the processor's average score of 36938 is nearly identical to the AMD Ryzen 5 5600F, which scores 36945 (a 0% delta). It is also very close to the AMD Ryzen 5 5500X3D (37018, -0.2% delta) and the AMD Ryzen AI 7 PRO 450 (37093, -0.4% delta). This indicates that in raw processing power, the Ultra 5 225 is on par with these alternatives, meaning any performance differences in To The Core would likely stem from other system components or platform features rather than a decisive CPU advantage.

The core count is notable for a desktop part, with 10 physical cores and 10 threads. This configuration is interesting for an idle game, as the genre often benefits from having dedicated cores for various game systems (e.g., one for UI, one for logic, one for rendering). The absence of hyper-threading might seem like a limitation, but the high boost clock of 4.90 GHz helps mitigate that in single-thread-heavy scenarios. The PassMark single-thread score of 4412 reinforces the processor's strength in tasks that cannot be easily parallelized, which is crucial for maintaining high minimum frame rates in simulation-heavy titles.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5090 is a monolithic powerhouse, equipped with 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. The GPU’s architecture is Blackwell 2.0, fabricated on a 5 nm process, and it features 21760 shading units. Its clock speeds are a base of 2017 MHz and a boost of 2407 MHz. This hardware configuration places the GPU in the 92nd percentile of all GPUs, with a formidable average benchmark score of 79842.

In To The Core, the GPU’s role is paramount. The data shows that the RTX 5090 is capable of producing enormous frame rates, even at 4K. At 3840x2160 with Low settings, the system hits 240 FPS, which reflects the raw fill rate and compute power of the Blackwell architecture. The 32 GB VRAM buffer is unlikely to be a limiting factor in this title; the game's textures and assets can easily be stored locally, and the 1.79 TB/s bandwidth ensures that data can be streamed to the GPU cores without delay.

The GPU's benchmark scores in synthetic tests like Passmark G3D (39650) and Geekbench Vulkan (376728) indicate strong DirectX 12 and Vulkan performance, which aligns with the game's likely rendering API. The RTX 5090’s nearest rivals in the benchmark database include the NVIDIA Tesla P100 PCIe 16 GB (deltaPct 0.3) and the AMD Radeon RX 6850M XT (deltaPct 1.1), but these are professional or mobile parts; the RTX 5090's consumer-focused feature set still allows it to dominate in gaming workloads. The GPU’s high pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are the raw metrics that explain why even at 4K Ultra, the system maintains 142 FPS.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals a classic scaling pattern, but with an interesting twist at the top end. Moving from 1920x1080 to 2560x1440, and then to 3840x2160, shows a clear decline in average frame rates across all settings, but the magnitude of the drop suggests the system is shifting from a CPU-limited state to a GPU-limited one.

At 1080p Low, the system achieves 625 FPS. When we move to 1440p Low, the FPS drops to 420, a reduction of 32.8%. This is a substantial drop, but it indicates that the CPU was the primary limiter at 1080p, as the GPU had ample headroom. However, the transition from 1440p Low (420 FPS) to 4K Low (240 FPS) is a 42.9% drop, which is more significant and suggests the GPU is now becoming the bottleneck. The RTX 5090 is being saturated by the increased pixel count.

The same trend holds for High settings. At 1080p High, the system produces 458 FPS. At 1440p High, it drops to 308 FPS (-32.8%), and at 4K High, it falls to 176 FPS (-42.9%). This consistent pattern across settings indicates that the scaling factor is primarily resolution-driven. The CPU is capable of maintaining high frame rates, but as the resolution increases, the GPU's workload grows proportionally, making the graphics card the limiting component.

The most telling data point is the 4K Ultra result of 142 FPS. While this is still a very high frame rate, it represents a 61.6% drop from the 1080p Low result of 625 FPS. This significant reduction underscores that even with a top-tier GPU, the demands of 4K rendering cannot be fully offset by a strong CPU. The system is well-balanced, but the GPU is unequivocally the component that determines the final FPS ceiling at higher resolutions. The benchmark results indicate that to achieve the highest possible frame rates, users should prioritize lowering resolution over lowering settings.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of the system's performance envelope. The following breakdown details the exact average frame rates for each tested configuration.

At 1920x1080, the system delivers its highest frame rates across all settings. With Low settings, it achieves 625 FPS. Moving to Medium settings, the average FPS drops to 528, with a minimum of 449 and a maximum of 608. High settings yield 458 FPS, and Ultra settings produce 369 FPS. This shows a clear progression, where the performance penalty for Ultra over Low is 256 FPS.

At 2560x1440, the frame rates scale down proportionally. Low settings produce 420 FPS. Medium settings average 355 FPS, with a minimum of 302 and a maximum of 409. High settings yield 308 FPS, and Ultra settings produce 248 FPS. The difference between Low and Ultra at this resolution is 172 FPS.

At 3840x2160, the system still maintains very high frame rates, though the impact of higher settings is more pronounced. Low settings yield 240 FPS. Medium settings average 203 FPS, with a minimum of 173 and a maximum of 234. High settings produce 176 FPS, and Ultra settings result in 142 FPS. The gap between Low and Ultra at 4K is 98 FPS, which shows that the GPU is working harder to maintain performance.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured data, the optimal settings depend on the user's display and performance goals. The data shows that the system is capable of high frame rates at all settings, but the choice of preset should be guided by the balance between visual fidelity and frame rate.

For users with a 1080p display, the High preset at 458 FPS is an excellent choice, as it provides a significant improvement in visual quality over Medium (528 FPS) while still delivering a frame rate that far exceeds any display's refresh rate. The jump to Ultra (369 FPS) offers diminishing returns in visual polish for a 19.4% reduction in FPS compared to High. The Low preset (625 FPS) is only useful for competitive scenarios where every single frame matters, but the visual sacrifice is substantial.

At 1440p, the High preset at 308 FPS is the recommended sweet spot. It provides enough headroom for high-refresh-rate monitors (240Hz+) while offering good visual quality. The Medium preset (355 FPS) is also viable if the user prefers maximum fluidity. Ultra settings (248 FPS) still clear the 240Hz threshold, but the extra load on the GPU is evident. The Low preset (420 FPS) is overkill for most displays and sacrifices too much visual quality.

For 4K displays, the Ultra preset at 142 FPS is surprisingly playable, especially for a game that doesn't require twitch reflexes. However, the High preset at 176 FPS offers a better balance, providing a 24% performance boost over Ultra with a minor visual downgrade. The Medium preset (203 FPS) is the best choice for users with high-refresh-rate 4K monitors (144Hz or higher), as it ensures the frame rate stays well above the refresh rate. The Low preset (240 FPS) is not recommended as it introduces a significant visual compromise for a marginal FPS gain over Medium.
