Roblox

Roblox is a notoriously CPU-bound sandbox title, yet the pairing of the AMD Ryzen 7 5700G with the NVIDIA GeForce RTX 2070 SUPER produces a frame-rate curve that is heavily dictated by the graphics card at higher resolutions. The measured data shows that this combo delivers exceptional performance at 1080p, but the scaling to 1440p and 4K reveals a predictable shift in bottleneck, moving from the processor to the GPU as pixel count increases.

Resolution Scaling

The FPS drop from 1080p to 4K is significant, though the exact magnitude depends heavily on the quality settings. At Low settings, the average frame rate falls from 338.8 FPS at 1920x1080 to 227.6 FPS at 2560x1440, and finally to 127.2 FPS at 3840x2160. This represents a 62.4% reduction from 1080p to 4K. The gap between Low and High settings also widens at higher resolutions, indicating that the GPU becomes the limiting factor.

At High settings, the scaling is steeper: 275.1 FPS at 1080p drops to 181.3 FPS at 1440p (a 34.1% decrease) and then to 103.6 FPS at 4K (a 62.3% decrease from 1080p). The Ultra preset shows the most dramatic drop, going from 219.9 FPS at 1080p to 147.5 FPS at 1440p and just 81.6 FPS at 4K. This pattern is classic GPU-bound behavior; the RTX 2070 SUPER, which sits in the 65th percentile of all GPUs, is being pushed harder as resolution increases.

The data suggests that the 5700G’s 8-core, 16-thread configuration is not the primary constraint at 4K. The gap between Low and Ultra at 4K is 45.6 FPS, whereas at 1080p it is 118.9 FPS. This compression of the settings-based delta at 4K confirms that the GPU’s pixel throughput is the wall, not the CPU’s ability to feed the renderer. The Ryzen 7 5700G’s single-thread score of 899 in 3dMark and 2930 in Cinebench R23 is more than sufficient to keep up with the GPU’s output at lower resolutions, but at 4K the GPU’s 448.0 GB/s memory bandwidth and 9.062 TFLOPS of FP32 compute become the decisive factors.

How This Combo Ranks

In the global database of tested combinations, this specific pairing of the Ryzen 7 5700G and RTX 2070 SUPER ranks 1107 out of 1800 combos for Roblox. This places it in the bottom 38.5% of all tested systems, which is surprising given the high frame rates achieved. The reason is that Roblox is an older title with a low graphical ceiling, meaning that even modest hardware can hit very high FPS. The comboRankInGame percentile is more about the raw speed of the parts relative to other pairings, not the playability of the game.

The Ryzen 7 5700G itself is a strong processor, sitting in the 83rd percentile of all CPUs. Its nearest rivals include the AMD Ryzen 7 6800U (0.3% slower), the Intel Xeon D-2752TER (0.4% faster), and the Intel Core 5 210H (0.5% faster). The RTX 2070 SUPER, meanwhile, is in the 65th percentile of GPUs, with its nearest rival being the NVIDIA RTX A400 (0.5% slower) and the AMD Radeon RX 5700 (2.5% slower). The fact that the combo ranks so low despite these strong individual components indicates that the combination is overkill for Roblox’s engine, which likely caps performance or fails to utilize the multi-threaded capabilities fully.

The 5700G’s 3dmark score of 6627 for 16 threads and 6629 for max threads shows good scaling, but Roblox does not appear to be a workload that benefits from more than a few cores. The 2-thread score of 1758 is relatively low, suggesting that the game’s main thread is the limiting factor. This is why the combo ranks lower than systems with faster single-core CPUs, even if they have fewer total cores.

FAQ

Q: Is the RTX 2070 SUPER the bottleneck at 4K Ultra settings?

A: Yes. The average FPS drops from 147.5 at 1440p Ultra to 81.6 at 4K Ultra, a 44.7% reduction. This steep decline, combined with the small gap between Low and Ultra at 4K (127.2 vs 81.6 FPS), indicates the GPU’s rendering pipeline is saturated.

Q: Can this combo maintain 60 FPS at 4K?

A: Yes, at all tested settings. Even the most demanding preset (Ultra at 3840x2160) yields an average of 81.6 FPS, which is well above the 60 FPS threshold. The minimum FPS is not provided, but the averages suggest a comfortable margin.

Q: How does the CPU affect performance at 1080p Low settings?

A: At 1080p Low, the average FPS is 338.8, which is likely CPU-limited. The Ryzen 7 5700G’s single-thread performance (899 in 3dMark single-thread) is the key metric here; the GPU is not being fully utilized at this resolution and setting.

Q: What is the performance gap between High and Ultra at 1440p?

A: At 2560x1440, High settings deliver 181.3 FPS, while Ultra delivers 147.5 FPS. This is a 23.0% reduction in frame rate for the higher preset, showing that Ultra has a measurable cost even at mid-range resolutions.

Q: Is the 8-core, 16-thread CPU necessary for this game?

A: The data suggests not. The 5700G’s 16-thread score (6629) is barely higher than its 8-thread score (5648) in 3dmark, indicating diminishing returns. Roblox likely uses only a fraction of the available threads.

Q: How does this combo compare to the GPU’s nearest rival?

A: The RTX 2070 SUPER is 2.5% faster than the AMD Radeon RX 5700 in average benchmark score. In Roblox, this translates to a small but measurable FPS advantage, though the CPU is often the limiting factor at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the combo is exceptionally fast. Low settings produce an average of 338.8 FPS, Medium drops to 306.7 FPS, High to 275.1 FPS, and Ultra to 219.9 FPS. The spread of 118.9 FPS between Low and Ultra shows that the GPU still has headroom even at the highest settings, as the CPU is capable of feeding it more frames.

Moving to 2560x1440, the averages are 227.6 FPS (Low), 207.8 FPS (Medium), 181.3 FPS (High), and 147.5 FPS (Ultra). The drop from 1080p to 1440p is approximately 32.8% for Low settings, but only 32.9% for High settings, indicating a consistent shift toward GPU limitation.

At 3840x2160, the numbers are 127.2 FPS (Low), 114.1 FPS (Medium), 103.6 FPS (High), and 81.6 FPS (Ultra). The gap between Low and Ultra narrows to 45.6 FPS, which is the smallest absolute difference across all resolutions. This confirms that the RTX 2070 SUPER’s 8 GB of GDDR6 memory and 256-bit bus are the main constraints at 4K.

All measurements are taken from dataIsMeasured, meaning they are empirical results rather than estimates. The lack of minFps and maxFps data means the analysis relies solely on averages, but the consistency of the scaling pattern across settings and resolutions provides a high degree of confidence in the bottleneck analysis.

CPU Role

The AMD Ryzen 7 5700G is a Zen 3 (Cezanne) architecture processor built on a 7 nm process. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. The CPU’s benchmark results show strong multi-threaded performance: a Cinebench R23 multicore score of 20755 and a Passmark multithread score of 24419. However, its single-thread scores are more relevant to Roblox: a Cinebench R23 single-core score of 2930 and a 3dmark single-thread score of 899.

In Roblox, the CPU’s role is primarily to process game logic and physics, which is largely single-threaded. The 5700G’s 16 MB of L3 cache and 51.2 GB/s memory bandwidth are sufficient to avoid stutters, but the game does not appear to scale with the CPU’s 16 threads. The 3dmark 2-thread score of 1758 is less than a third of the 16-thread score of 6629, showing that the processor’s strength lies in multi-threaded workloads that Roblox does not utilize.

The CPU’s integrated Radeon Vega 8 graphics are irrelevant in this configuration, as the system uses the discrete RTX 2070 SUPER. The 5700G’s PCIe Gen 3 interface (16 lanes) is also not a bottleneck, as the GPU’s PCIe 3.0 x16 bus matches. Overall, the data shows that the Ryzen 7 5700G provides more than enough computational headroom for Roblox, but its high core count does not translate into higher FPS in this specific title. The bottleneck at 1080p is the CPU’s single-thread speed, while at 4K it is the GPU’s rendering capacity. This combo is powerful, but Roblox’s engine limits the return on investment for such high-end hardware.
