To The Core

# To The Core with AMD Ryzen 9 9900X + NVIDIA GeForce RTX 5090

The AMD Ryzen 9 9900X paired with the NVIDIA GeForce RTX 5090 delivers an extraordinary experience in To The Core, an Idle genre title that proves remarkably scalable across resolutions and settings. This combo ranks 5th out of 1,756 tested configurations, placing it in the top 0.3% of all pairings. The measured frame rates are uniformly high, yet the scaling patterns reveal a system where the GPU becomes the primary limiter only at 4K Ultra, while lower resolutions expose a CPU-bound ceiling that still exceeds 600 FPS.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but expected for a high-refresh pairing. At Low settings, the average FPS falls from 632.3 at 1920x1080 to 423.4 at 2560x1440, then to 242.7 at 3840x2160 — a cumulative reduction of 61.6% from 1080p to 4K. This pattern indicates that at 1080p Low, the system is heavily CPU-limited; the Ryzen 9 9900X's 12 cores and 24 threads are being pushed far beyond typical gaming workloads, and the RTX 5090 is nowhere near saturated.

At Ultra settings, the scaling is more moderate but still pronounced: 373.3 FPS at 1080p, 249.3 at 1440p, and 145.9 at 4K. The 4K Ultra figure represents a 60.9% drop from 1080p Ultra, showing that the GPU's rendering load at 3840x2160 with maximum settings finally engages the RTX 5090's full capabilities. The RTX 5090's 32 GB of GDDR7 memory on a 512-bit bus with 1.79 TB/s bandwidth ensures that even at 4K Ultra, memory bandwidth is not a bottleneck.

The intermediate settings tell the same story. At Medium, 1080p produces 536.3 FPS, dropping to 359.1 at 1440p and 207.2 at 4K. At High, the figures are 463.7, 313.6, and 180.5 respectively. The consistent pattern across all settings — roughly a 30-40% drop from 1080p to 1440p, then another 40-45% drop from 1440p to 4K — suggests that pixel count scaling is the dominant factor, with the CPU holding frame rates at 1080p and the GPU taking over as resolution climbs.

GPU Role

The NVIDIA GeForce RTX 5090, built on the Blackwell 2.0 architecture with the GB202 chip, is the clear performance driver at higher resolutions. Its boost clock of 2407 MHz and base clock of 2017 MHz, combined with 21,760 shading units, 680 TMUs, and 176 ROPs, deliver the raw compute needed to maintain playable frame rates even at 4K Ultra. The GPU's FP32 throughput of 104.8 TFLOPS and texture rate of 1,636.8 GTexel/s are directly relevant to To The Core's rendering demands, which scale with resolution and settings.

The RTX 5090's 32 GB of GDDR7 memory is a defining feature. At 4K Ultra, where the game's asset streaming and render targets expand, this capacity prevents any memory-related stutters. The memory clock runs at 1750 MHz with 28 Gbps effective speed, yielding a bandwidth of 1.79 TB/s — more than sufficient for an idle game that doesn't stress memory bandwidth as heavily as AAA shooters. The GPU's 170 RT cores and 680 tensor cores are present, though To The Core's Idle genre likely doesn't leverage ray tracing or DLSS extensively; the benchmark results show raw rasterization performance dominating.

The GPU's average benchmark score of 84,306 places it in the 94th percentile of all GPUs, with nearest rivals including the RTX 5090 D (0.1% ahead) and RTX 5050 Mobile (0.2% behind). In To The Core, the RTX 5090's 4K Ultra result of 145.9 FPS demonstrates that even the most demanding preset leaves headroom for high-refresh 4K displays. The gap between Low and Ultra at 4K — 242.7 vs. 145.9 — shows a 40% performance cost for maxing out settings, a reasonable trade-off for visual fidelity.

Measured FPS Breakdown

At 1920x1080, the results are exceptional across all settings. Low averages 632.3 FPS, Medium 536.3, High 463.7, and Ultra 373.3. These numbers indicate that at 1080p, the CPU is the limiting factor — the RTX 5090 could likely render more frames if the game's logic thread weren't capped. The 41.0% difference between Low and Ultra at 1080p shows that settings do impact performance, but the absolute values are so high that any modern display would be saturated.

At 2560x1440, the figures remain impressive: Low hits 423.4 FPS, Medium 359.1, High 313.6, and Ultra 249.3. The drop from 1080p to 1440p averages around 33%, consistent with the 1.78x pixel increase. The 1440p Ultra result of 249.3 FPS is still well above the refresh rates of most high-end monitors, confirming that this combo is overkill for 1440p gaming in this title.

At 3840x2160, the GPU begins to assert itself. Low averages 242.7 FPS, Medium 207.2, High 180.5, and Ultra 145.9. The scaling from Low to Ultra at 4K shows a 39.9% performance cost, which is the largest relative drop across resolutions. This indicates that at 4K, the RTX 5090's compute resources are the primary determinant of frame rate, and the GPU's 104.8 TFLOPS FP32 throughput is being taxed meaningfully. The 4K Ultra result of 145.9 FPS is still excellent for a maxed-out preset, making 4K gaming with high refresh rates entirely viable.
