Roblox

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 4070 SUPER delivers exceptional performance in Roblox, with measured frame rates that far exceed the requirements of most displays. The data indicates that this combination is heavily CPU-bound at lower resolutions, while the GPU becomes more relevant at 4K. The following analysis breaks down the optimal settings, competitive ranking, component roles, and scaling behavior based strictly on the measured results.

Settings Recommendations

The measured data shows a clear progression in frame rates across the four available presets at each resolution. At 1080p, the Low preset delivers an average of 559.9 FPS, which is the highest figure recorded for this combo at any resolution or setting. Medium follows closely at 505.5 FPS, while High drops to 450.6 FPS and Ultra falls to 365.2 FPS. For users with high-refresh-rate monitors, the Low preset at 1080p offers the most headroom, though the gap between Low and Medium is only 54.4 FPS, suggesting that Medium remains viable for competitive play without sacrificing much responsiveness.

At 1440p, the pattern remains consistent. Low produces 372.8 FPS, Medium 339.3 FPS, High 301.8 FPS, and Ultra 244.2 FPS. The delta between Low and Ultra here is 128.6 FPS, which is significant but still leaves Ultra well above the 144 Hz threshold common on modern displays. Given that Roblox is a sandbox title where visual fidelity often enhances the experience, the Medium preset at 1440p represents the best balance in the measured data: it retains 339.3 FPS while offering substantially better visuals than Low.

At 4K, the frame rates compress considerably. Ultra still manages 141 FPS, which is playable on most displays, but High reaches 168.8 FPS and Medium 192.3 FPS. Low tops out at 213.3 FPS. The jump from Ultra to Medium at 4K yields a 51.3 FPS improvement, which is the largest relative gain between adjacent presets at this resolution. For 4K users, the Medium preset is the strongest recommendation: it provides a 36.4% uplift over Ultra while remaining visually rich enough for a sandbox game.

The ultimate verdict from the data is that Medium is the sweet spot across all resolutions. At 1080p it delivers 505.5 FPS, at 1440p 339.3 FPS, and at 4K 192.3 FPS — each figure comfortably exceeds the refresh rate of typical gaming monitors. High preset is only worth considering if the user prioritizes image quality over raw frame rate, as it costs between 9.8% and 12.2% performance relative to Medium depending on resolution.

How This Combo Ranks

The AMD Ryzen 9 7900X + NVIDIA GeForce RTX 4070 SUPER combination ranks 327th out of 1800 tested combos in Roblox, placing it in the top 18.2% of all configurations in the database. This is a strong showing for a CPU that sits at the 93rd percentile among all processors and a GPU at the 84th percentile among all graphics cards. The rank indicates that while this combo excels, there are 326 other pairings that achieve higher average frame rates in this specific title.

The CPU’s nearest rivals help contextualize this ranking. The Intel Core Ultra 5 235 scores 50598 on average, which is a 0.1% delta from the Ryzen 9 7900X’s 50556 average benchmark score — essentially a statistical tie. The AMD Ryzen 9 5900XT trails by 0.4%, and the Intel Core i7-13850HX by 0.5%. The closest competitor, the Intel Core i9-13980HX, is 0.8% behind. These sub-1% deltas suggest that the 7900X’s 12-core, 24-thread Zen 4 architecture provides no meaningful advantage over these rivals in Roblox, which is a title that rarely scales past a few threads.

For the GPU, the RTX 4070 SUPER’s nearest rivals paint a similar picture. The NVIDIA RTX A6000 scores 42653, a 0.2% delta, and the AMD Radeon RX 7650 GRE scores 42723, a 0.3% delta. The AMD Radeon Pro 580X and NVIDIA Tesla M40 are 1.4% and 1.6% behind, respectively. The tight clustering of these scores — all within 2% — indicates that Roblox’s rendering workload does not differentiate strongly between GPUs in this performance tier. The combo’s rank of 327 likely stems more from the CPU’s strong single-thread performance than from the GPU, as evidenced by the frame rate scaling discussed later.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER brings 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The GPU is built on the Ada Lovelace architecture with a base clock of 1980 MHz and a boost clock of 2475 MHz. These specifications position it as a high-end card, and its measured performance in Roblox reflects this — at 4K Ultra it still produces 141 FPS, which is well above the 60 FPS standard for most games.

However, the data reveals that the GPU is not the primary bottleneck in Roblox at lower resolutions. At 1080p, the difference between Low and Ultra is 194.7 FPS (559.9 vs 365.2), but at 4K that same difference shrinks to 72.3 FPS (213.3 vs 141). This compression suggests that as resolution increases, the GPU becomes more engaged, while at 1080p the CPU’s single-thread performance — the Ryzen 9 7900X scores 6168 in Cinebench R23 single-core and 4238 in Passmark single-thread — limits the frame rate.

The GPU’s 84th percentile ranking among all graphics cards, combined with its 29995 Passmark G3D score, shows that it is a capable performer. Yet the fact that the RTX 4070 SUPER’s nearest rivals include the RTX A6000 and RX 7650 GRE with deltas under 0.5% implies that Roblox’s geometry and draw-call throughput are not stressing the GPU’s 7168 shading units or 80 ROPs to their limits. The 12 GB VRAM is ample for Roblox’s modest texture requirements, and the 504.2 GB/s bandwidth is far beyond what this title needs, even at 4K Ultra.

A: No. The 12 GB of GDDR6X memory with 504.2 GB/s bandwidth is far more than Roblox requires. The GPU’s 84th percentile ranking and 29995 Passmark G3D score confirm it is not VRAM-constrained in this title.

Q: How much performance is lost when moving from 1080p to 4K at the same settings?

A: At High settings, the average drops from 450.6 FPS at 1080p to 168.8 FPS at 4K, a 62.5% reduction. At Low settings, the drop is from 559.9 to 213.3 FPS, a 61.9% reduction.

Resolution Scaling

The measured data shows a substantial frame rate penalty as resolution increases, but the rate of decline varies by preset. At High settings, the average frame rate drops from 450.6 FPS at 1080p to 301.8 FPS at 1440p (a 33.0% reduction), then to 168.8 FPS at 4K (a 44.1% reduction from 1440p). This two-step decline indicates that the CPU is still the primary limiter at 1440p, but the GPU begins to take over by 4K.

The Low preset exhibits a similar but shallower curve: 559.9 FPS at 1080p, 372.8 FPS at 1440p (a 33.4% drop), and 213.3 FPS at 4K (a 42.8% drop). The fact that Low and High lose nearly the same percentage of performance between 1080p and 1440p — 33.4% vs 33.0% — suggests that the CPU’s instruction throughput is the bottleneck at both presets in this resolution range. The Ryzen 9 7900X’s single-thread score of 6168 in Cinebench R23 and 4238 in Passmark single-thread is the limiting factor here, as Roblox is known for its single-threaded rendering pipeline.

At 4K, the picture changes. The gap between Low (213.3 FPS) and High (168.8 FPS) is 44.5 FPS, whereas at 1080p the same gap is 109.3 FPS. This narrowing indicates the GPU is now the primary constraint. The RTX 4070 SUPER’s 2475 MHz boost clock and 198.0 GPixel/s pixel rate are being pushed harder, and the 12 GB GDDR6X memory’s 504.2 GB/s bandwidth becomes more relevant. The data suggests that at 4K, the GPU’s fill rate is the limiting factor, while at 1080p and 1440p, the CPU’s single-thread performance caps the frame rate.

The Ultra preset shows the steepest scaling curve: 365.2 FPS at 1080p, 244.2 FPS at 1440p (a 33.1% drop), and 141 FPS at 4K (a 42.3% drop). This pattern mirrors the other presets, confirming that the limiting component shifts from CPU to GPU as resolution climbs. For users targeting 4K, the data shows that even Ultra settings remain playable at 141 FPS, but Medium at 192.3 FPS offers the best balance of performance and visual quality at that resolution.
