Roblox

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4070 SUPER pairing delivers exceptional performance in Roblox, a sandbox title that scales dramatically across resolutions and settings. The data shows a combo that is heavily CPU-bound at lower resolutions, with the GPU only becoming a limiting factor at 4K Ultra. This analysis breaks down the measured FPS, component roles, and how this specific configuration stacks up against the broader benchmark database.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and reveals a classic bottleneck shift. At 1080p Low, the combo produces 561.5 FPS, which drops to 372.8 FPS at 1440p Low (a 33.6% reduction), and further to 211.4 FPS at 4K Low (another 43.3% drop). This pattern indicates that at lower resolutions, the CPU is the primary driver, while the GPU becomes increasingly stressed as pixel count rises.

The scaling is more pronounced at higher settings. At Ultra, the 1080p score of 367 FPS falls to 242.7 FPS at 1440p (a 33.9% reduction), and then to 140.6 FPS at 4K (a 42.1% reduction from 1440p). The consistent ~33-43% drops per resolution step suggest the RTX 4070 SUPER is handling the geometry and shading load well, but the 4K Ultra result of 140.6 FPS is the first point where the GPU's 12 GB GDDR6X memory and 192-bit bus become apparent limiting factors.

Notably, the gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference is 194.5 FPS (561.5 vs 367). At 4K, the difference narrows to 70.8 FPS (211.4 vs 140.6). This indicates that at 4K, the GPU is the bottleneck regardless of settings, while at 1080p, the CPU's 12 cores and 24 threads can push frame rates to extremes, making the GPU's workload less relevant.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER is built on the Ada Lovelace architecture with 7,168 shading units and 80 ROPs. Its boost clock of 2475 MHz and 504.2 GB/s of memory bandwidth from 12 GB of GDDR6X on a 192-bit bus provide ample headroom for Roblox's stylized visuals. The data confirms this: at 4K Medium, the combo still delivers 195.2 FPS, which is far above the 60 FPS threshold for smooth gameplay.

The GPU's pixel rate of 198.0 GPixel/s and texture rate of 554.4 GTexel/s are more than sufficient for Roblox's blocky aesthetic, but the 4K Ultra score of 140.6 FPS shows the card is working hard. The FP32 performance of 35.48 TFLOPS suggests raw compute is not the issue; rather, the 80 ROPs and memory bandwidth become the limiting factors at 4K. The card's 84th percentile ranking among all GPUs and its average benchmark score of 42,576 place it in the upper tier, but the nearest rivals (NVIDIA RTX A6000 at -0.2% delta and AMD Radeon RX 7650 GRE at -0.3% delta) show it is not class-leading.

At 1080p, the GPU is almost idle relative to the CPU. The 561.5 FPS Low score confirms the RTX 4070 SUPER's efficiency, but the 12 GB VRAM is never stressed at this resolution. The card's 220 W TDP and dual-slot design make it a practical choice for most builds, and the 1x 16-pin power connector requires a modern PSU.

CPU Role

The AMD Ryzen 9 9900X is the star of this pairing. With 12 cores, 24 threads, and a boost clock of 5.60 GHz, it provides massive single-threaded and multi-threaded performance. The 3DMark single-thread score of 1286 and Cinebench R23 single-core score of 6555 indicate excellent per-core performance, which is critical for Roblox's physics and scripting workloads.

The CPU's 94th percentile ranking among all CPUs is well-earned. Its average benchmark score of 54,450 is nearly identical to the AMD Ryzen 9 9900X3D (deltaPct of -0.4%), meaning the 3D V-Cache variant offers no meaningful advantage in this title. The Intel Core i7-14700F is 0.7% ahead, while the Intel Core Ultra 5 245K and 245KF are 1.5% and 1.8% behind, respectively. This tight grouping means the 9900X is competitive with top-tier alternatives, and the 64 MB of shared L3 cache helps with Roblox's asset streaming.

At 1080p Low, the 561.5 FPS result is a clear indicator that the CPU is the primary driver. The 3DMark 16-thread score of 12,552 and max-thread score of 13,929 show that the CPU can feed the GPU at high rates, but even with this power, the 1080p Ultra score of 367 FPS suggests the CPU is hitting a ceiling with Roblox's engine. The 4.40 GHz base clock and 5.60 GHz boost clock allow for rapid single-threaded response, which is essential for Roblox's server-client synchronization.

The CPU's 120 W TDP and AMD Socket AM5 platform support DDR5 memory with dual-channel bandwidth of 89.6 GB/s. This memory bandwidth is sufficient for Roblox's needs, though the 16,630 million transistors on a 4 nm process indicate a dense, power-efficient design.

How This Combo Ranks

In the benchmark database, this combination of AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4070 SUPER ranks 315th out of 1,800 tested combos for Roblox. This places it in the top 17.5% of all configurations, which is respectable but not elite. The rank reflects the balance between the high-end CPU and the mid-high-end GPU.

The ranking suggests that while the CPU is top-tier, the GPU holds the combo back from the very top spots. Combos with faster GPUs like the RTX 4090 or RX 7900 XTX would likely rank higher, especially at 4K Ultra where the GPU is the bottleneck. However, for a 1440p or 1080p gaming setup, this combo is overkill for Roblox, delivering 242.7 FPS at 1440p Ultra and 450 FPS at 1080p High.

The 315th rank out of 1,800 means there are 314 combos that perform better in Roblox, but many of those likely use significantly more expensive GPUs. The data shows that for the price of the RTX 4070 SUPER (launch MSRP of 599 USD), the performance is strong, but the CPU's 499 USD launch MSRP is a substantial investment for a game like Roblox.

Measured FPS Breakdown

At 1920x1080, the FPS is extremely high across all settings. Low delivers 561.5 FPS, Medium drops to 507.6 FPS (a 9.6% reduction), High yields 450 FPS (an 11.3% reduction from Medium), and Ultra produces 367 FPS (an 18.4% reduction from High). These numbers indicate that even at Ultra, the game is playable on a 360Hz monitor, though the CPU is clearly the limiting factor.

At 2560x1440, the performance remains excellent. Low produces 372.8 FPS, Medium drops to 338.8 FPS (9.1% reduction), High delivers 299.8 FPS (11.5% reduction), and Ultra yields 242.7 FPS (19.0% reduction). The 1440p Ultra result is still above 240 FPS, making this combo ideal for high-refresh-rate 1440p gaming.

At 3840x2160, the GPU starts to show its limits. Low delivers 211.4 FPS, Medium drops to 195.2 FPS (7.7% reduction), High produces 172.5 FPS (11.6% reduction), and Ultra falls to 140.6 FPS (18.5% reduction). The 4K Ultra score is still above 120 FPS, but the gap between Low and Ultra (70.8 FPS) shows that the GPU is now the bottleneck.

The data reveals a consistent pattern: at each resolution, the drop from Low to Medium is smaller (7.7-9.6%) than the drop from High to Ultra (18.4-19.0%). This suggests that the Ultra preset includes effects that are disproportionately expensive on the RTX 4070 SUPER, likely related to shadows or post-processing.
