Roblox

The Intel Core i7-13700K paired with the NVIDIA GeForce RTX 5090 D is the top-performing combination for Roblox, securing the #1 spot out of 3,010 tested combos. This pairing leverages a 16-core, 24-thread processor with a 5.40 GHz boost clock alongside a 32 GB, 512-bit GDDR7 graphics card to deliver frame rates that far exceed display refresh rates, making it an unequivocal choice for competitive and high-fidelity play. The benchmark data shows that this combo is not merely capable but overwhelmingly dominant, with performance headroom that allows for maximum settings at high resolutions without compromise.

CPU Role

The Intel Core i7-13700K is a Raptor Lake-S architecture processor with 16 cores and 24 threads, operating at a base clock of 3.40 GHz and a boost clock of 5.40 GHz. Its structure includes an 80 KB L1 cache per core, a 2 MB L2 cache per core, and a shared 30 MB L3 cache, which helps manage the diverse workloads Roblox presents. Benchmarks like Cinebench R23 show a multicore score of 30,745 and a single-core score of 2,116, while Geekbench records a multicore score of 19,429 and a single-core score of 2,529. These figures indicate a processor with substantial parallel processing power and strong single-thread performance.

In the context of Roblox's measured results, the CPU is rarely the limiting factor at lower resolutions. At 1080p with Low settings, the combo achieves 776 FPS, which is an extremely high frame rate that suggests the engine's simulation and physics threads are being fed efficiently by the CPU. The processor’s 3DMark scores are telling: 12,412 for max threads and 1,136 for single-thread, with a 16-thread score of 10,717. This scaling from single-thread to multi-thread workloads shows that while Roblox may not use all 16 cores, the i7-13700K has enough headroom to handle any background tasks or game logic spikes without causing stutters.

When compared to its nearest rivals, the i7-13700K has an average benchmark score of 46,881, which is 0.2% lower than the AMD Ryzen 9 5900 (46,971) and 0.3% lower than the AMD Ryzen AI 9 HX PRO 375 (47,022), but 0.5% higher than both the AMD Ryzen 9 7845HX and Intel Xeon w3-2535 (46,654 and 46,653 respectively). These deltas are negligible in real-world gaming, and the CPU’s 89th percentile ranking among all CPUs confirms it is a high-tier performer. For Roblox, the data suggests the CPU provides ample single-thread speed for the game's main loop, while the multi-core capacity ensures that the 5090 D is never starved for data.

GPU Role

The NVIDIA GeForce RTX 5090 D is a Blackwell 2.0 architecture GPU with a 5 nm process node and a massive 92,200 million transistors on a 750 mm² die. It features 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. The GPU’s boost clock is 2,407 MHz, and it has 21,760 shading units, 680 TMUs, and 176 ROPs. Its raw compute capability is 104.8 TFLOPS for FP32, which translates to a Passmark G3D score of 44,065 and a Geekbench OpenCL score of 310,674.

In Roblox, the GPU’s role becomes evident as resolution and settings increase. At 4K Ultra, the combo drops to 191 FPS, which is still very high but indicates the GPU is now the primary bottleneck. The GPU’s 92nd percentile ranking among all GPUs shows it is a top-tier part, but its nearest rivals in the database are lower-end mobile and data center parts like the AMD Radeon RX 6650M XT (1.1% higher) and the NVIDIA Tesla P100 PCIe 16 GB (2.4% lower). This is a quirk of the database’s comparison pool; in practice, the 5090 D’s 32 GB VRAM and high bandwidth allow it to handle Roblox’s texture streaming and draw calls without issue.

The measured data shows that the GPU is not the limiting factor until 4K Ultra. The FPS drop from 4K Low (293 FPS) to 4K Ultra (191 FPS) is a 34.8% reduction, which is a significant performance cost for visual fidelity. However, even at 4K Ultra, the frame rate is far above the 60 FPS target, indicating that the GPU has more than enough power for this game. The GPU’s memory clocks of 1,750 MHz (28 Gbps effective) and high pixel rate of 423.6 GPixel/s ensure that it can fill pixels rapidly, which is critical for maintaining high FPS at 4K.

Resolution Scaling

Resolution scaling reveals the shift in bottleneck from the CPU to the GPU. At 1080p, the combo is heavily CPU-bound, as evidenced by the High settings score of 625 FPS. Moving to 1440p High drops the frame rate to 417 FPS, a 33.3% decrease, which is a typical scaling curve. At 4K High, the score is 236 FPS, a 43.4% drop from 1440p, indicating that the GPU is now doing more work but still has headroom.

The trend is consistent across all settings. For Low settings, the FPS drops from 776 at 1080p to 518 at 1440p (a 33.2% decrease) and then to 293 at 4K (a 43.4% decrease from 1440p). Medium settings follow a similar pattern: 706 at 1080p, 471 at 1440p, and 267 at 4K. Ultra settings show the steepest drop: 507 at 1080p, 338 at 1440p, and 191 at 4K. The FPS drops from 1440p to 4K are consistently around 43-44%, which suggests that the GPU is the primary limiter at 4K.

The data indicates that at 1080p and 1440p, the CPU is doing a significant amount of work, as the frame rates are extremely high and the GPU has significant headroom. At 4K, the GPU’s fill rate and shader throughput become the limiting factors, but even then, the 5090 D’s power ensures that the game remains playable at high refresh rates. The min FPS data for Medium settings shows that the game is relatively stable, with a 227 FPS minimum at 4K and a 600 FPS minimum at 1080p, indicating no major frame time spikes.
