Roblox

The AMD Ryzen 7 7800X3D paired with the NVIDIA GeForce RTX 5070 delivers exceptionally high frame rates in Roblox, a Sandbox title released in 2006. The measured data shows this combination achieving triple-digit average FPS at every tested setting and resolution, with the lowest average being 133.2 FPS at 4K Ultra. This performance profile indicates that the system is overwhelmingly powerful for the game's engine, with the data suggesting that the CPU's substantial cache and the GPU's modern architecture both contribute to a smooth experience that far exceeds typical display refresh rates.

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

The AMD Ryzen 7 7800X3D is an 8-core, 16-thread processor from the 7000 series, built on the Zen 4 architecture (codename Raphael) using a 5 nm process at TSMC. It operates at a base clock of 4.20 GHz and a boost clock of 5.00 GHz, with a 120 W TDP. A defining feature is its large 96 MB shared L3 cache, which is critical for gaming workloads that benefit from high-speed data access. The CPU also supports DDR5 memory over a dual-channel bus with a bandwidth of 83.2 GB/s, and it includes Radeon Graphics as integrated graphics.

In the context of Roblox, the CPU's role is substantial. The benchmark results show that at 1080p Low, the average FPS reaches 543.3, which is the highest measured value in the entire dataset. This suggests that even at the lowest settings, the CPU is capable of feeding the GPU with enough frames to exceed 500 FPS. The single-thread performance is strong, as indicated by a 3dmark_single_thread score of 959 and a Geekbench single-core score of 2725. Roblox, being a title with a long history, often relies on single-threaded performance for game logic and physics, and the 7800X3D's architecture provides a solid foundation.

The data shows that the CPU's performance does not bottleneck the system in this game. The average benchmark score for the CPU is 31580, placing it in the 87th percentile of all CPUs. Its nearest rivals include the Intel Core i7-12700F, which has an average score of 31543 (a delta of 0.1%), and the AMD Ryzen 9 5980HX at 31495 (delta of 0.3%). These are marginal differences, indicating that the 7800X3D is at the top of its class. In Roblox, the CPU's ability to maintain high minimum frame rates is likely more important than raw multi-threaded throughput, and the 96 MB L3 cache helps ensure that frequently accessed game data is kept close to the cores. The measured FPS at 1080p Ultra (352.7) versus 1080p Low (543.3) shows a 35% drop, which implies that the GPU becomes more involved as settings increase, but the CPU still holds its own in providing a high baseline.

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

The NVIDIA GeForce RTX 5070 is based on the Blackwell 2.0 architecture, utilizing the GB205 chip fabricated on a 5 nm process at TSMC. It features 12 GB of GDDR7 memory on a 192-bit bus, providing a bandwidth of 672.0 GB/s. The GPU operates at a base clock of 2325 MHz and a boost clock of 2512 MHz, with memory running at 1750 MHz (28 Gbps effective). It has 6144 shading units, 192 TMUs, and 80 ROPs, along with 48 RT cores and 192 tensor cores. The GPU's raw compute capability is rated at 30.87 TFLOPS for FP32, and it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The TDP is 250 W, suggesting a need for a robust power supply, and it connects via PCIe 5.0 x16.

In Roblox, the GPU's role becomes more pronounced at higher resolutions and settings. At 4K Ultra, the average FPS drops to 133.2, which is the lowest in the dataset, indicating that the GPU is under the most stress at this configuration. The VRAM capacity of 12 GB is more than sufficient for a game with the graphical complexity of Roblox, which typically does not require large texture budgets. The data shows a clear scaling pattern: at 1440p High, the average FPS is 292, while at 4K High, it falls to 163.1, a reduction of about 44%. This suggests that the GPU is the limiting factor at higher resolutions, as the CPU's performance remains constant.

The GPU's average benchmark score is 41687, placing it in the 83rd percentile of all GPUs. Its nearest rivals include the AMD Radeon Pro 5300 (score 41610, delta 0.2%) and the NVIDIA GeForce RTX 3090 (score 41441, delta 0.6%). These comparisons show that the RTX 5070 performs at a level comparable to previous high-end cards, but its efficiency and feature set are more modern. For Roblox, the GPU's ability to handle high frame rates at 1080p and 1440p is evident, with averages exceeding 200 FPS at most settings. The benchmark results imply that the GPU is not a bottleneck at lower resolutions, but at 4K, the increased pixel count does reduce performance, as seen in the 206.8 FPS at 4K Low versus 434.2 FPS at 1080p High.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 7 7800X3D and the NVIDIA GeForce RTX 5070 ranks 392nd out of 1800 tested combos in Roblox. This places it in the top 22% of all systems tested for this game. While this might seem modest given the high frame rates, it is important to note that 1800 combos include many other high-end configurations. The rank reflects the overall measured performance, which is already excellent.

The data indicates that this combo is not the absolute top performer, but it is well above the median. The 392nd rank suggests that there are 391 combos that achieve higher average FPS across all tested scenarios. However, the measured FPS values are so high that the differences between ranks may be marginal in real-world usage. For instance, at 1080p Low, the combo achieves 543.3 FPS, which is near the practical limit for most displays. The rank is influenced by all resolution and setting combinations, including 4K Ultra, where the score is 133.2 FPS. This suggests that the combo's overall ranking is dragged down by the 4K Ultra result, which is still playable but not as extreme as the lower-resolution results.

Compared to other combos, the CPU's 87th percentile and GPU's 83rd percentile indicate that both components are high-end, but the combo rank of 392 out of 1800 shows that there are more powerful pairings available. The data implies that for a game like Roblox, which is not graphically demanding by modern standards, the limiting factor at 4K Ultra is the GPU, but the overall rank is still strong. The high FPS at all settings ensures that this combo provides a fluid experience, even if it does not top the charts.

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

At 1920x1080, the average FPS varies significantly with settings. Low settings yield 543.3 FPS, Medium yields 494.2 FPS, High yields 434.2 FPS, and Ultra yields 352.7 FPS. This shows a clear trend: as settings increase, the frame rate decreases, but even at Ultra, the average is above 350 FPS. The difference between Low and Ultra is 190.6 FPS, a 35% reduction, which is substantial but still leaves headroom for high-refresh-rate monitors.

At 2560x1440, the averages are lower but still impressive. Low settings produce 362.9 FPS, Medium produces 330.1 FPS, High produces 292 FPS, and Ultra produces 233.3 FPS. The drop from 1080p to 1440p is notable; for example, at High settings, the FPS goes from 434.2 to 292, a reduction of 142.2 FPS (about 33%). This indicates that the GPU is working harder to render more pixels, but the performance remains well above 200 FPS.

At 3840x2160, the averages are the lowest in the dataset. Low settings achieve 206.8 FPS, Medium achieves 188.1 FPS, High achieves 163.1 FPS, and Ultra achieves 133.2 FPS. The transition from 1440p to 4K shows a further significant drop; for example, at High settings, the FPS goes from 292 to 163.1, a reduction of 128.9 FPS (about 44%). This confirms that 4K is the most demanding resolution, and the GPU becomes the primary bottleneck. However, even at 4K Ultra, the average FPS of 133.2 is above 120, making it suitable for high-refresh-rate gaming at that resolution.

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

The scaling from 1080p to 4K reveals the relationship between the CPU and GPU. At Low settings, the FPS drops from 543.3 at 1080p to 206.8 at 4K, a reduction of 62%. At Medium settings, the drop is from 494.2 to 188.1, a 62% reduction. At High settings, the drop is from 434.2 to 163.1, a 62% reduction. At Ultra settings, the drop is from 352.7 to 133.2, a 62% reduction. The consistency of this 62% drop across all settings is a strong indicator that the GPU is the limiting component as resolution increases.

The data shows that the CPU's performance is sufficient to maintain high frame rates at all resolutions, as the FPS only falls when the GPU is tasked with more pixels. If the CPU were the bottleneck, we would expect the FPS to be similar across resolutions, but the significant drop from 1080p to 4K proves that the GPU is the constraint. The RTX 5070's 12 GB VRAM and 672.0 GB/s bandwidth are adequate for 4K, but the raw pixel throughput is not enough to match the CPU's potential at lower resolutions.

The scaling behavior suggests that at 1080p and 1440p, the system is likely CPU-bound at Low settings, but as settings increase, the GPU becomes more involved. At 4K, the GPU is clearly the limiting factor. This is typical for a high-end CPU paired with a mid-to-high-end GPU. The 62% drop from 1080p to 4K is substantial, but the absolute FPS values remain high, indicating that the combo is well-balanced for most gaming scenarios.
