To The Core

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

The NVIDIA GeForce RTX 4080 in this combo is built on the Ada Lovelace architecture with a 5 nm process from TSMC. Its base clock runs at 2205 MHz and boosts to 2505 MHz, while the 16 GB of GDDR6X memory operates at 1400 MHz with an effective 22.4 Gbps transfer rate across a 256-bit bus. That configuration yields 716.8 GB/s of memory bandwidth, which is substantial for a game like To The Core that scales heavily with resolution.

The RTX 4080's 9728 shading units, 304 TMUs, and 112 ROPs give it a pixel rate of 280.6 GPixel/s and a texture rate of 761.5 GTexel/s. In practical terms, this means the GPU can push enormous frame counts even at 4K, as the measured data confirms. The card's FP32 throughput of 48.74 TFLOPS is identical to its FP16 output (1:1 ratio), which is typical for this generation and indicates strong raw compute headroom.

For To The Core, an idle game, the GPU's role is less about complex physics or AI workloads and more about raw rasterization throughput. The RTX 4080's 76 RT cores and 304 tensor cores are present, but the game's measured performance suggests it doesn't heavily tax those specialized units. Instead, the combination of high clock speeds and wide memory bus ensures that frame rates remain high even when settings are pushed to Ultra.

The CPU side of this combo is the AMD Ryzen 9 5900X, a 12-core, 24-thread processor based on Zen 3 (Vermeer) architecture. It runs at a 3.70 GHz base clock and boosts to 4.80 GHz, with a 105 W TDP. The 64 MB of L3 cache and dual-channel DDR4 memory support (51.2 GB/s bandwidth) are adequate for feeding the RTX 4080 in this title. The CPU's 3DMark scores — 9075 for 16 threads, 10075 for max threads, and 941 for single-thread — indicate strong multi-threaded performance, though To The Core appears to be GPU-bound at most settings.

The GPU's benchmark profile reinforces this: its PassMark G3D score of 34457 and 3DMark Steel Nomad DX12 score of 6567 place it in the 86th percentile among all GPUs. The RTX 4080's nearest rival, the RTX 4080 SUPER, scores 54209 on average, a mere 0.1% difference, meaning this card is effectively at parity with its successor in synthetic tests. The AMD Radeon Pro W5700X is 1.1% ahead, while the Radeon RX 6750 GRE 12 GB and Radeon 8060S are 2.6% and 2.7% behind, respectively.

How This Combo Ranks

The combination of the Ryzen 9 5900X and RTX 4080 ranks 298th out of 3725 tested combos in To The Core, placing it in the top 8% of all configurations. This is a strong result, though not elite — the top 297 combos likely feature newer CPUs or higher-tier GPUs that edge out this pairing in specific scenarios.

The CPU's percentile ranking of 87th among all processors, with an average benchmark score of 41376, puts it slightly above the Intel Core Ultra 7 366H (41263, +0.3%) and Intel Core Ultra 7 356H (41215, +0.4%). It also edges out the AMD Ryzen AI 5 PRO 440 (41208, +0.4%) but falls 0.5% behind the Intel Core i7-14650HX (41576). These are tight margins, indicating the 5900X is still competitive in 2024-2025 workloads, but it's not a class leader.

The GPU's 86th percentile ranking, with an average benchmark score of 54247, shows similar positioning. The RTX 4080 is essentially tied with the RTX 4080 SUPER (54209, +0.1% for the SUPER), which means the original card holds up well despite being end-of-life. The gap to the AMD Radeon Pro W5700X (54828, -1.1% for the RTX 4080) is small, and the Radeon RX 6750 GRE 12 GB (55698) and Radeon 8060S (55757) are actually ahead by 2.6% and 2.7%, respectively — though those are different market segments.

In To The Core specifically, the combo's rank of 298 out of 3725 suggests that the pairing is well-balanced for this title. The game's idle genre means it's not particularly demanding on either component, but the high refresh rates measured indicate that both the CPU and GPU are contributing effectively. The 5900X's 12 cores and 24 threads provide ample headroom for any background tasks or game logic, while the RTX 4080's raw throughput handles the rendering without bottlenecking.

Resolution Scaling

The measured FPS data shows clear scaling patterns across resolutions. At 1080p with Low settings, the combo achieves 531 FPS average. Moving to 1440p Low drops that to 371 FPS (a 30% reduction), and at 4K Low it falls to 212 FPS (a 43% reduction from 1440p). This scaling is typical for a GPU-bound scenario — the CPU has enough headroom at lower resolutions, but the GPU's workload increases proportionally with pixel count.

At High settings, the pattern is similar but with lower absolute numbers: 405 FPS at 1080p, 272 FPS at 1440p (33% drop), and 156 FPS at 4K (43% drop from 1440p). The consistency of these percentage drops across settings suggests that the limiting factor shifts from CPU at 1080p to GPU at 4K, but the RTX 4080 remains capable enough to maintain playable frame rates even at the highest resolution.

The Medium settings row provides the only min/max FPS data in the pack. At 1080p Medium, the average is 467 FPS with a minimum of 397 and maximum of 537. At 1440p Medium, the average drops to 314 FPS with a minimum of 267 and maximum of 361. At 4K Medium, the average is 180 FPS with a minimum of 153 and maximum of 207. These ranges indicate that frame pacing is consistent — the spread between min and max is roughly 30% of the average at each resolution, which is acceptable for an idle game.

The Ultra settings show the most demanding scenario: 326 FPS at 1080p, 219 FPS at 1440p (33% drop), and 125 FPS at 4K (43% drop). The fact that 4K Ultra still maintains 125 FPS average is impressive for this combo, suggesting the RTX 4080's 16 GB VRAM and 716.8 GB/s bandwidth are sufficient for the game's highest preset without memory pressure.

The scaling pattern — roughly 30% reduction from 1080p to 1440p and another 43% from 1440p to 4K — indicates that the GPU is the primary bottleneck at higher resolutions. The CPU's single-thread score of 941 in 3DMark and 1527 in Cinebench R23 are strong enough to avoid becoming a limiting factor, even at 1080p where frame rates exceed 500 FPS.

Settings Recommendations

Based on the measured data, the optimal settings for this combo depend on the target resolution and refresh rate. At 1080p, even Ultra settings deliver 326 FPS average, which exceeds the refresh rate of virtually all monitors. The jump from Ultra to High at 1080p yields 405 FPS (a 24% increase), while Medium gives 467 FPS (43% over Ultra) and Low gives 531 FPS (63% over Ultra). For most users, High or Ultra at 1080p is the best choice — the visual quality difference between presets is likely more noticeable than the frame rate difference beyond 300 FPS.

At 1440p, the situation is similar. Ultra delivers 219 FPS, High gives 272 FPS (24% increase), Medium provides 314 FPS (43% increase), and Low reaches 371 FPS (69% increase). A 1440p monitor with a 240 Hz refresh rate would benefit from High or Medium settings, as both exceed 240 FPS. Ultra at 219 FPS is still playable but may not fully utilize a high-refresh display.

At 4K, the choices become more meaningful. Ultra delivers 125 FPS, which is above the 60 FPS threshold for smooth gameplay but below the 144 Hz that many 4K monitors offer. High settings at 156 FPS (25% increase over Ultra) are a better match for 144 Hz displays. Medium at 180 FPS (44% increase) and Low at 212 FPS (70% increase) provide even more headroom, but the visual trade-off may not be worth it for an idle game where detail is less critical.

The data suggests that High settings offer the best balance of visual quality and performance across all resolutions. The 24% FPS increase from Ultra to High is consistent at every resolution, and the min FPS data (where available) shows that Medium settings have a tighter frame pacing — the 4K Medium min of 153 FPS is 85% of the average, while the 1080p Medium min of 397 FPS is also 85% of the average. This consistency indicates that Medium and High presets are well-optimized for this combo.
