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

The AMD Ryzen 5 7600 is a 6-core, 12-thread processor from the 7000 series, built on the Zen 4 architecture with a 5 nm process at TSMC. Its base clock is 3.80 GHz, boosting to 5.10 GHz, and it carries 32 MB of shared L3 cache alongside 1 MB of L2 per core. This desktop part, released in January 2023, sits in the 83rd percentile of all CPUs benchmarked in the database, with an average benchmark score of 26,617.

In the context of Roblox, the CPU's single-thread performance is particularly relevant. The Ryzen 5 7600 scores 999 in 3DMark single-thread, 1,363 in Cinebench R20 single-core, and 3,246 in Cinebench R23 single-core. These numbers indicate robust per-core throughput, which matters for a game that often has a primary simulation or scripting thread. The multi-threaded scores are equally respectable: 6,503 in 3DMark max threads, 22,992 in Cinebench R23 multicore, and 27,058 in Passmark multithread. The 12 threads allow background tasks and physics to spread across cores, but the measured FPS in Roblox suggests that the CPU is not the primary constraint at most settings.

The nearest rival comparisons show the Ryzen 5 7600 is effectively tied with several heavy hitters. It sits 0.2% above the AMD Ryzen 7 5800X3D (average score 26,574), 0.2% above the AMD EPYC 8024P (26,555), and 0.3% above the Intel Core i9-11900K (26,546). It trails the Intel Core i9-12900HK by 0.2% (26,672). The deltaPct values are all under a third of a percent, meaning the Ryzen 5 7600 delivers essentially equivalent CPU throughput to those parts in aggregate benchmarks. For Roblox, this parity means the processor will not be the bottleneck—the GPU and resolution scaling will dictate the frame rates.

The CPU's memory support includes DDR5 with dual-channel access and a bandwidth of 83.2 GB/s. This bandwidth, combined with the 32 MB L3 cache, helps feed the GPU quickly. In the measured FPS data, the lowest average frame rate recorded is 73.7 FPS at 4K Ultra, which is still far from a CPU-limited scenario. The highest is 309.7 FPS at 1080p Low, which approaches the kind of frame rates where CPU overhead could start to matter, yet the Ryzen 5 7600's strong single-thread score (3,910 in Passmark single-thread) keeps it ahead of the game's demands.

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

The NVIDIA GeForce RTX 3060 Ti is an Ampere-architecture GPU on an 8 nm Samsung process, with a die size of 392 mm² and 17,400 million transistors. It features 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s of bandwidth. The base clock is 1,410 MHz with a boost of 1,665 MHz, and memory runs at 1,750 MHz (14 Gbps effective). The GPU has 4,864 shading units, 152 texture mapping units, 80 ROPs, 38 RT cores, and 152 tensor cores, yielding 16.20 TFLOPS of FP32 compute.

This GPU sits in the 69th percentile of all GPUs benchmarked, with an average benchmark score of 25,120. Its nearest rivals include the AMD Radeon RX 6700M (average score 25,180, deltaPct -0.2%), the AMD Radeon RX 6600 (25,235, -0.5%), the AMD Radeon 890M (25,246, -0.5%), and the AMD Radeon RX 580 2048SP (25,287, -0.7%). The negative deltaPct values for these rivals mean the RTX 3060 Ti scores slightly lower than each in aggregate, though the differences are under 1%. In Passmark G3D, the RTX 3060 Ti scores 20,349, and in 3DMark Steel Nomad DX12 it scores 2,626.

For Roblox, the GPU's 8 GB VRAM is sufficient for the game's asset sizes, even at 4K Ultra, where the measured average FPS drops to 73.7. The memory bandwidth of 448.0 GB/s helps maintain texture throughput, and the 80 ROPs ensure pixel fill rates are adequate—the pixel rate is 133.2 GPixel/s. The GPU's FP32 throughput of 16.20 TFLOPS provides headroom for the game's lighting and effects, but the data shows that at lower resolutions the frame rates scale with settings, indicating the GPU is often the limiting factor.

The RTX 3060 Ti supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which covers Roblox's rendering requirements. The measured FPS at 1080p Ultra is 200.2, which is lower than the 244.4 at 1080p High, showing that Ultra settings impose a measurable GPU cost. The gap between Low and Ultra settings at each resolution is consistent with GPU-bound behavior, as detailed in the resolution scaling section.

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

The measured FPS data shows a clear pattern of GPU-bound scaling across resolutions. At 1080p Low, the average FPS is 309.7, which drops to 206.3 at 1440p Low (a 33.4% reduction) and then to 118.8 at 4K Low (a 42.4% reduction from 1440p). This scaling is typical of a GPU-limited scenario, where the CPU has ample headroom and the render load increases with pixel count.

At 1080p High, the average FPS is 244.4. Moving to 1440p High yields 166.7 (a 31.8% drop), and 4K High yields 93.9 (a 43.7% drop from 1440p). The relative drops are similar across settings, indicating that the GPU's compute and memory bandwidth are the primary constraints. The RTX 3060 Ti's 448.0 GB/s bandwidth and 16.20 TFLOPS are being taxed more heavily as resolution rises, while the Ryzen 5 7600's strong single-thread performance means the CPU is not the limiting factor.

The Ultra setting shows the steepest curve. At 1080p Ultra, the average FPS is 200.2. At 1440p Ultra, it falls to 136 (a 32.1% drop), and at 4K Ultra it reaches 73.7 (a 45.8% drop from 1440p). The 4K Ultra result is the lowest measured frame rate in the entire dataset, and the gap between 4K High (93.9) and 4K Ultra (73.7) is 21.5%, which is larger than the gap between 1080p High and 1080p Ultra (18.1%). This suggests that Ultra settings add a proportionally heavier load at higher resolutions, likely due to increased shader complexity and texture filtering.

The Medium setting sits between Low and High, with 278 FPS at 1080p, 189.8 at 1440p, and 108.6 at 4K. The scaling from 1080p to 1440p is 31.7%, and from 1440p to 4K is 42.8%. These percentages are consistent across all settings, reinforcing that the GPU is the limiting component. If the CPU were the bottleneck, the 1080p results would show less variation between settings, as the CPU would cap frame rates regardless of GPU load. Instead, the 1080p Low result (309.7) is over 50% higher than the 1080p Ultra result (200.2), proving the GPU is doing the heavy lifting.
