Roblox

Roblox is a peculiar case in the hardware testing world. It's a sandbox title with a massive user base, but its rendering demands scale very differently than most AAA shooters or open-world RPGs. Looking at the measured FPS data for the Intel Core i5-14600K and NVIDIA GeForce RTX 4070 Ti SUPER, the results reveal a system that is heavily overqualified for the task, yet still offers insights into how this game behaves across different resolutions and settings.

The most striking takeaway from the data is that this combination is never challenged, even at maximum settings. The numbers are so high that the bottleneck shifts away from the GPU and onto the CPU's single-thread performance and the game's engine limitations. This analysis will break down the resolution scaling, the role of the GPU and CPU, and how this specific combo ranks against the other 1,800 tested configurations.

Resolution Scaling

The FPS deltas between 1080p and 4K are revealing. At 1080p High settings, the combo delivers an average of 479.1 FPS. Moving to 1440p High drops that to 320.2 FPS, and at 4K High, it lands at 183.1 FPS. This is a classic pattern of a game that is heavily CPU-bound at lower resolutions. The GPU has plenty of headroom at 1080p, so the frame rate is likely capped by the CPU's ability to process the game's logic and draw calls. As the resolution increases, the GPU begins to take on more work, which is why we see the frame rate scale down in a predictable manner.

The scaling from High to Ultra settings further confirms this. At 4K, the jump from High (183.1 FPS) to Ultra (143.5 FPS) is a significant 21.6% drop in performance. This shows that the Ultra preset introduces a substantial load on the GPU, likely through increased shadow quality, anti-aliasing, or other pixel-heavy effects. However, even at 4K Ultra, the 143.5 FPS average is far beyond what most monitors can display, indicating that the GPU is still not the limiting factor. The data suggests that the RTX 4070 Ti SUPER is capable of running the game at over 140 FPS at 4K Ultra, and the only reason it isn't higher is the software's limitations.

At the lower end, the story is different. At 1080p Low, the system hits 596 FPS. This is the highest frame rate recorded in the entire dataset, and it suggests that the game engine is hitting a hard ceiling. The difference between 1080p Low (596 FPS) and 1080p Medium (538.9 FPS) is only 57 FPS, which is a smaller relative drop than what we see between High and Ultra at 4K. This indicates that at 1080p, the CPU is the primary constraint. The GPU is so fast that even with reduced graphical settings, it is waiting for the CPU to feed it data. The performance gap between 1080p and 1440p is also telling; the 394.2 FPS at 1440p Low is still exceptionally high, suggesting the GPU is only just beginning to have an impact at this resolution.

GPU Role

The NVIDIA GeForce RTX 4070 Ti SUPER is a formidable piece of hardware, and its role in Roblox is to provide an overpowered safety net. With 16 GB of GDDR6X memory on a 256-bit bus, it has a bandwidth of 672.3 GB/s. This is more than sufficient for Roblox's texture and asset streaming, which rarely needs more than a few gigabytes of VRAM. The 2340 MHz base clock and 2610 MHz boost clock are high, but they don't need to work hard here. The GPU's compute potential, rated at 44.10 TFLOPS for FP32, is largely untapped in this session.

The benchmark results show that the GPU is not the bottleneck. The 3DMark Steel Nomad DX12 score is 5569, and the PassMark G3D score is 31811. These are solid numbers that place the GPU in the 86th percentile of all GPUs. However, in Roblox, the GPU's workload is relatively simple. The performance difference between 4K High (183.1 FPS) and 4K Low (223 FPS) is only 39.9 FPS, which is a much smaller percentage difference than what you would see in a more demanding title. This indicates that even at 4K, the game is not fully utilizing the GPU's shading units, ROPs, or texture units. The RTX 4070 Ti SUPER is essentially coasting. It is a top-tier card that is being asked to do a mid-range job, and it does so without breaking a sweat. The game's performance is so high that it seems the GPU is waiting for the CPU to send more instructions.

How This Combo Ranks

Looking at the broader picture, the combo's rank in Roblox is 217 out of 1800 tested combinations. This places it in the top 12% of all systems tested. This is an impressive rank, but it's not in the top 10 or even the top 100. The reason is that Roblox's performance is likely more sensitive to CPU single-core speed than to raw GPU power. The i5-14600K is a strong CPU, but there are faster processors available that can push the frame rate even higher, especially at 1080p where the CPU bottleneck is most pronounced.

The CPU's benchmark scores support this theory. The Cinebench R23 single-core score is 4642, and the Geekbench single-core score is 2803. These are strong numbers, but there are CPUs with higher single-thread performance that would likely rank higher in this specific game. The combo is ranked 217th, which is still an exceptional result, but it shows that the i5-14600K + RTX 4070 Ti SUPER is not the absolute peak configuration for Roblox. The data suggests that a CPU with even faster single-core performance, paired with a similar GPU, would likely achieve higher FPS and a better rank. The GPU's high score of 48704 (average benchmark) and 86th percentile placement is less relevant here because the game is not leveraging it to its full extent.

Measured FPS Breakdown

Here is the complete set of measured average FPS values for this configuration:

• 3840x2160 (4K)
• Ultra: 143.5 FPS
• High: 183.1 FPS
• Medium: 202 FPS
• Low: 223 FPS
• 2560x1440 (1440p)
• Ultra: 258.7 FPS
• High: 320.2 FPS
• Medium: 358.5 FPS
• Low: 394.2 FPS
• 1920x1080 (1080p)
• Ultra: 385.1 FPS
• High: 479.1 FPS
• Medium: 538.9 FPS
• Low: 596 FPS

The data shows a clear trend. At 1080p, the frame rates are astronomical, approaching 600 FPS. The scaling to 1440p is roughly a 20-30% reduction, and the scaling to 4K is another 40-50% reduction. This is a classic sign of a game that is not heavily GPU-bound. The fact that the 4K High score of 183.1 FPS is still higher than the 1080p Ultra score of 385.1 FPS is 47.5% lower, showing a steep drop, but the absolute numbers remain high.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor based on the Raptor Lake architecture. It has a base clock of 3.50 GHz and a boost clock of 5.30 GHz. For Roblox, the key specification is not the core count but the single-core performance. Roblox's engine is not known for heavy multi-threading, and the data confirms this. The CPU's Cinebench R23 multi-core score is 32881, which is strong, but the single-core score of 4642 is what matters most for the game.

The performance at 1080p Low (596 FPS) strongly suggests that the CPU is hitting a limit. The difference between 1080p Low and 1080p Ultra is 210.9 FPS, which is a massive gap. This indicates that the CPU can process the game logic at a certain speed, and the GPU is easily able to render the frames. When you increase the settings, the GPU work increases, but the CPU is already at its limit. The boost clock of 5.30 GHz helps to maximize this single-threaded performance. The processor's L3 cache is 24 MB, which is shared, and the L2 cache is 2 MB per core, which helps with data access. The i5-14600K is a capable gaming CPU, but in Roblox, its role is to feed the GPU as fast as possible, and it succeeds admirably. The data shows that the CPU is the limiting component, but it is still fast enough to provide an exceptional experience.
