Roblox

The AMD Ryzen 7 7700 paired with the NVIDIA GeForce RTX 5070 Ti delivers exceptional performance in Roblox, with measured frame rates that far exceed the demands of the game across all tested resolutions and presets. The data, derived from measured FPS values, shows a configuration that is heavily GPU-limited at lower resolutions and gradually shifts toward a more balanced workload as pixel count increases. This analysis breaks down the results by resolution, GPU characteristics, CPU contribution, and how this specific combo ranks among all tested combinations.

Resolution Scaling

The measured FPS results show a clear and predictable scaling pattern from 1080p to 4K. At 1920x1080 with Low settings, the combo achieves an average of 606 FPS. Moving to 2560x1440 at the same Low setting, the average drops to 404 FPS, a reduction of 33.3%. At 3840x2160 Low, the average falls further to 229 FPS, which is 43.3% lower than the 1440p result and 62.2% lower than the 1080p result. This steep decline indicates that the rendering load is rapidly increasing with pixel count, as expected for a game that scales well with resolution.

The Medium presets show a similar trend. At 1080p Medium, the average is 551 FPS, dropping to 368 FPS at 1440p Medium and 208 FPS at 4K Medium. The drop from 1080p to 1440p is 33.2%, and from 1440p to 4K is 43.5%. The 4K Medium result also shows a minimum FPS of 177 and a maximum of 239, indicating some variance at this higher resolution. The High preset follows the same pattern: 487 FPS at 1080p, 325 FPS at 1440p, and 184 FPS at 4K. The Ultra preset yields 395 FPS at 1080p, 264 FPS at 1440p, and 149 FPS at 4K.

What stands out is that even at 4K Ultra, the average FPS remains above 144, which is higher than most displays' refresh rates. The scaling between Low and Ultra at any given resolution is consistent: at 1080p, Ultra is 34.8% lower than Low (606 to 395), at 1440p it is 34.7% lower (404 to 264), and at 4K it is 34.9% lower (229 to 149). This near-constant percentage drop across resolutions suggests that the performance penalty from raising settings is proportional, not additive, meaning the game's graphics options affect frame times in a fairly consistent way.

The data indicates that at 1080p, the CPU is likely the limiting factor, as the FPS is extremely high across all settings, and the GPU is not being fully utilized. At 4K, the GPU becomes the primary constraint, but even then, the FPS remains high. The largest FPS jump between settings occurs from Ultra to High at 1080p, where the average increases from 395 to 487 FPS. This suggests that the Ultra preset introduces a significant cost, likely from effects that are not visually critical at lower resolutions. The scaling pattern is smooth and linear, with no sudden cliffs, indicating a well-optimized engine for this hardware.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is a Blackwell 2.0 architecture GPU built on a 5 nm process, with a chip size of 378 mm² and a transistor count of 45,600 million. It has 16 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 896.0 GB/s. The base clock is 2295 MHz, boosting to 2452 MHz. This memory capacity and bandwidth are substantial for a game like Roblox, which, while not graphically demanding, can benefit from high frame rates and fast memory transactions.

In Roblox, the GPU's role is to deliver the high frame rates seen in the measured FPS. At 1080p, the GPU is not the limiting factor, as the FPS is likely capped by the CPU's capability to feed the render pipeline. The 16 GB GDDR7 memory is far more than Roblox needs at any resolution, so the game's memory footprint is not a concern. The GPU's bandwidth of 896.0 GB/s is sufficient to handle the texture and vertex data at 4K Ultra without becoming a bottleneck, as evidenced by the 149 FPS result at that extreme setting.

The GPU's performance in this game is also reflected in its benchmark scores. The Passmark G3D score is 32974, and the Geekbench OpenCL score is 212363. These scores place the GPU at the 86th percentile of all GPUs, indicating strong overall performance. However, the nearest rivals in terms of average benchmark score are interesting: the AMD Radeon RX Vega 64 has a score of 50001 (deltaPct -0.1), the Intel Arc A550M has 49737 (deltaPct 0.4), the AMD Radeon RX 6900 XT has 50951 (deltaPct -2), and the AMD Radeon RX 6800 XT has 48477 (deltaPct 3.1). These deltas are small, meaning the RTX 5070 Ti's average benchmark score is within a few percent of these cards. In Roblox, the actual FPS shows the RTX 5070 Ti delivering frame rates that are consistent with its high percentile ranking, but the game itself does not stress the GPU to its limits, especially at lower resolutions.

The GPU's 3DMark Steel Nomad DX12 score of 6604 is a sign of modern API performance, which Roblox may utilize in its rendering pipeline. The GPU also supports DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6, ensuring compatibility with the game's rendering backends. The pixel rate of 235.4 GPixel/s and texture rate of 686.6 GTexel/s are more than adequate for the game's scene complexity. Overall, the GPU is a high-performance part that is not heavily stressed in this game, as the FPS figures exceed 200 in most settings.

The High preset offers a slightly lower FPS than Medium but may provide better visuals for those who prefer it. However, the medium preset provides a better frame rate per visual step. The Low preset yields the highest FPS, but it may not be the best visual experience. For users with high refresh rate monitors, the Medium preset at 1080p or 1440p is recommended. At 1440p, Medium yields 368 FPS, which is well above 240 Hz, and at 4K, Medium yields 208 FPS, which is above 144 Hz. The Ultra preset is only recommended for those who prioritize visual quality over frame rate, but even at 4K, it still offers 149 FPS.

The best experience per the measured rows is the Medium preset. At 1080p, it delivers 551 FPS on average, which is a 20.5% decrease from Low but a 16.2% increase over High. At 1440p, Medium provides 368 FPS, which is 13.2% lower than Low but 13.2% higher than High. At 4K, Medium gives 208 FPS, which is 9.2% lower than Low but 13.0% higher than High. The Medium preset offers a consistent balance, with a min FPS of 468 at 1080p, 313 at 1440p, and 177 at 4K, and a max FPS of 634, 423, and 239, respectively. The variance is moderate, making it a stable choice.

Measured FPS Breakdown

The measured FPS is broken down by resolution and settings as follows:

• 1920x1080 (1080p): Low: 606 avg. Medium: 551 avg (min 468, max 634). High: 487 avg. Ultra: 395 avg.
• 2560x1440 (1440p): Low: 404 avg. Medium: 368 avg (min 313, max 423). High: 325 avg. Ultra: 264 avg.
• 3840x2160 (4K): Low: 229 avg. Medium: 208 avg (min 177, max 239). High: 184 avg. Ultra: 149 avg.

At 1080p, the spread from Low to Ultra is 211 FPS (606 to 395). At 1440p, the spread is 140 FPS (404 to 264). At 4K, the spread is 80 FPS (229 to 149). The minimum and maximum values for the Medium presets show that the 1080p Medium has a range of 166 FPS (468 to 634), 1440p Medium has a range of 110 FPS (313 to 423), and 4K Medium has a range of 62 FPS (177 to 239). This indicates that the game's frame time variance increases at higher resolutions, leading to a wider range of FPS.

The average FPS at High settings is consistently 0.8× the Medium average at each resolution: 487/551=0.88, 325/368=0.88, and 184/208=0.88. This shows a consistent cost for the High preset. The Ultra preset is 0.79× the Medium at 1080p (395/551), 0.72× at 1440p (264/368), and 0.72× at 4K (149/208). This suggests that the Ultra preset has a larger relative cost at higher resolutions.

CPU Role

The AMD Ryzen 7 7700 is an 8-core, 16-thread processor from the 7000 series, based on the Zen 4 architecture and code-named Raphael. It has a base clock of 3.80 GHz and a boost clock of 5.30 GHz. This CPU has a 65 W TDP and supports DDR5 memory with dual-channel and a bandwidth of 83.2 GB/s. The L3 cache is 32 MB shared, and the L2 is 1 MB per core.

In Roblox, the CPU's performance is crucial for delivering high frame rates. At 1080p, the FPS is so high (up to 606) that the CPU must be able to handle the game's logic and physics at that speed. The 8-core/16-thread configuration is more than adequate for a game like Roblox, which is often lightly threaded. The high boost clock of 5.30 GHz, combined with the Zen 4 architecture, provides strong single-thread performance, which is important for the primary game thread.

The CPU's benchmark scores reflect its capabilities: Cinebench R23 multi-core score is 18760, single-core is 1930, and Geekbench multi-core is 15371, single-core is 2525. The Passmark multi-thread score is 34470, and single-thread is 4063. The CPU's percentile versus all CPUs is 87, and its average benchmark score is 40081. This places it in the top tier of CPUs.

In the game, the CPU's role is evident in the 1080p results. At 1080p Low, the average FPS is 606, which is 32.7% higher than the 1440p Low score of 404. This suggests that at 1080p, the CPU is the limiting factor, as the GPU is not being fully utilized. The FPS difference from 1080p to 1440p is larger than the resolution change would suggest if the GPU were the bottleneck. At 4K, the CPU is less of a bottleneck, as the FPS drops to 229 at Low, indicating the GPU is now the primary limit.

The CPU's 16 threads may not be fully utilized in Roblox, but the high single-thread performance ensures that the game's main thread can keep up with the high FPS. The 65W TDP is low, meaning the CPU is efficient and less likely to thermal throttle, which helps maintain consistent performance. The memory bandwidth of 83.2 GB/s is also sufficient for the game's data needs. The CPU's performance in this game is not a concern, as the FPS is high at all resolutions, even with the CPU being the limiting factor at 1080p.

The CPU's performance is also reflected in its nearest rivals. The AMD Ryzen AI 9 365 has an average score of 40048 (deltaPct 0.1), Intel Core 5 221E has 40144 (deltaPct -0.2), AMD Ryzen 9 270 has 40246 (deltaPct -0.4), and Intel Core i9-13905H has 40313 (deltaPct -0.6). These deltas are very small, meaning the 7700 is essentially tied with these CPUs in average performance. In Roblox, the 7700's high clock speed and Zen 4 architecture provide the single-thread performance needed to hit 606 FPS at 1080p.
