Roblox

The Intel Core i7-13700K paired with the AMD Radeon RX 5700 XT delivers exceptional performance in Roblox, consistently producing high frame rates across all tested resolutions and settings. The data shows a system that is heavily GPU-limited at lower resolutions, where the CPU's 16 cores and 24 threads are more than sufficient to feed the graphics card, while at 4K the GPU's 8 GB of VRAM and RDNA 1.0 architecture become the defining factors in performance scaling. This analysis breaks down the measured FPS data to explain how each component contributes to the final experience.

FAQ

Q: What is the highest average frame rate recorded for this combo in Roblox?

A: The highest average FPS recorded is 301, achieved at 1920x1080 resolution with Low settings. This indicates the system has massive headroom at the most common esports resolution, suggesting the CPU is rarely the limiting factor in this game.

Q: How does the Ultra preset at 4K compare to the Low preset at 1080p?

A: The Ultra preset at 3840x2160 yields an average of 74 FPS, while the Low preset at 1920x1080 produces 301 FPS. This represents a 227 FPS difference, or roughly a 4x performance gap, demonstrating that resolution and settings have a compounding effect on the rendering load.

Q: Is the CPU or GPU more likely to be the bottleneck in this configuration?

A: At 1080p, the GPU is the clear bottleneck, as evidenced by the frame rate scaling from 301 FPS at Low to 196 FPS at Ultra. At 4K, the GPU's limitations become even more pronounced, with the Ultra preset dropping to 74 FPS, while the CPU's benchmark scores (89th percentile) suggest it has ample computational headroom.

Q: What is the measured frame time variance at 1440p Medium settings?

A: At 2560x1440 with Medium settings, the system records an average of 183 FPS, with a minimum of 155 FPS and a maximum of 210 FPS. This 55 FPS spread indicates some frame pacing variability, though the average remains well above the 144 Hz refresh rate common on modern monitors.

Q: How does this combo rank among all tested systems for Roblox?

A: The combination ranks 2750th out of 3711 tested combos in Roblox. This places it in the 74th percentile, meaning it outperforms roughly three-quarters of all tested configurations, despite the GPU being from an older generation.

Q: Does the GPU's 8 GB VRAM appear to limit performance in this game?

A: The data does not show a hard VRAM limit, as the system still achieves 91 FPS at 4K High settings. However, the significant drop to 74 FPS at 4K Ultra suggests that memory bandwidth and capacity may be contributing to the scaling penalty, though Roblox's sandbox nature typically keeps texture memory demands moderate.

GPU Role

The AMD Radeon RX 5700 XT is the primary driver of Roblox's visual output, built on the RDNA 1.0 architecture with a 7 nm process node. Its 8 GB of GDDR6 memory operates on a 256-bit bus, providing 448.0 GB/s of bandwidth, which is crucial for handling the blocky textures and simple geometry that Roblox presents. The GPU's boost clock of 1905 MHz and game clock of 1755 MHz, with a base clock of 1605 MHz, demonstrate a substantial overclocking headroom that helps maintain consistent frame delivery.

The measured FPS data reveals how the GPU's compute resources scale with settings. With 2560 shading units and a texture rate of 304.8 GTexel/s, the card can process the simple shader work Roblox requires at very high speeds. This is reflected in the 1080p results, where even the Ultra preset achieves 196 FPS. The GPU's pixel rate of 121.9 GPixel/s becomes more relevant at higher resolutions, explaining why the 4K Ultra setting drops to 74 FPS — the fill rate requirements of 3840x2160 pixels strain the RDNA 1.0 architecture more than the CPU's ability to feed draw calls.

The 8 GB VRAM capacity is adequate for Roblox's asset sizes, but the data suggests it is not a limiting factor even at 4K. The frame rate scaling from High (91 FPS) to Ultra (74 FPS) at 4K represents a 18.7% performance loss for what is likely a marginal visual gain in a block-based game. This indicates that the GPU's raw compute and memory bandwidth, rather than capacity, are the primary constraints at higher settings. Interestingly, the GPU's 59th percentile ranking among all GPUs places it in the mid-range, yet it still delivers playable frame rates at 4K in this specific title, underscoring how Roblox's lightweight rendering engine benefits even modest hardware.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a clear GPU-bound scenario. At 1080p Low, the system produces 301 FPS, which drops to 201 FPS at 1440p Low, and further to 113 FPS at 4K Low. This represents a 62.5% reduction in frame rate when moving from 1080p to 1440p, and a 62.4% reduction from 1440p to 4K. These consistent scaling ratios confirm that the GPU's pixel processing capabilities are the limiting factor, as the CPU's performance remains constant regardless of resolution.

The scaling becomes even more pronounced at higher settings. At Ultra, the frame rates are 196 FPS at 1080p, 131 FPS at 1440p, and 74 FPS at 4K. The drop from 1080p to 1440p is 33.2%, while the drop from 1440p to 4K is 43.5%. This non-linear scaling at Ultra settings suggests that the GPU's shading units and ROPs are being saturated more aggressively as resolution increases, with the 4K Ultra workload pushing the RDNA 1.0 architecture to its limits.

The medium settings data provides the most complete picture, with minimum and maximum frame rates recorded. At 1080p Medium, the system averages 274 FPS with a minimum of 233 FPS and maximum of 315 FPS. At 1440p Medium, the average drops to 183 FPS with a minimum of 155 FPS and maximum of 210 FPS. At 4K Medium, the average is 103 FPS with a minimum of 88 FPS and maximum of 119 FPS. The consistency of these frame ranges indicates that the GPU maintains stable performance without thermal throttling, though the increasing gap between minimum and maximum at lower resolutions suggests some CPU-side frame submission variability.

The data implies that for this combo, 1440p is the sweet spot where the GPU is sufficiently loaded to prevent CPU bottlenecking, while 1080p leaves the GPU underutilized. At 4K, the GPU becomes the definitive constraint, but the system still delivers playable frame rates across all settings, which is remarkable for a GPU from 2019.

Settings Recommendations

Based on the measured FPS data, the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p Medium, the system delivers 274 FPS, which is only 9% lower than Low settings but provides significantly better visual fidelity. The minimum frame rate of 233 FPS ensures smooth gameplay even in complex scenes with many players or physics objects, which is common in Roblox's sandbox experiences.

At 1440p, Medium settings produce 183 FPS, which is ideal for high-refresh-rate monitors. The 155 FPS minimum ensures that even the most demanding moments stay above the 144 Hz threshold, making this the recommended setting for competitive play. The jump to High settings at 1440p reduces the average to 161 FPS, which is still playable but leaves less headroom for frame drops in intense moments.

For 4K, the Medium preset at 103 FPS is the most practical choice, as it provides a smooth experience on standard 60 Hz displays while maintaining visual quality. The High preset at 91 FPS is also viable, but the Ultra preset at 74 FPS introduces noticeable frame pacing issues on variable refresh rate monitors. The Low preset at 4K (113 FPS) offers no visual benefit for the performance gain, as Roblox's art style does not require the extra frame rate at that resolution.

The data suggests avoiding Ultra settings entirely on this combo. At every resolution, Ultra provides the lowest frame rates with minimal visual improvement over High, given Roblox's simple geometry and texture work. The 1080p Ultra setting at 196 FPS is still usable, but the 4K Ultra at 74 FPS approaches the edge of playability for fast-paced games.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its peak performance range. Low settings produce 301 FPS average, Medium produces 274 FPS with a minimum of 233 FPS and maximum of 315 FPS, High produces 242 FPS, and Ultra produces 196 FPS. The 105 FPS spread between Low and Ultra shows that the GPU has significant headroom even at the highest settings, with all presets exceeding the typical 144 Hz refresh rate.

At 2560x1440, the frame rates remain high but show more GPU dependence. Low settings deliver 201 FPS, Medium delivers 183 FPS with a minimum of 155 FPS and maximum of 210 FPS, High delivers 161 FPS, and Ultra delivers 131 FPS. The 70 FPS spread between Low and Ultra indicates that the GPU is starting to feel the resolution increase, but the system still maintains excellent performance across all settings.

At 3840x2160, the GPU's limitations become apparent. Low settings produce 113 FPS, Medium produces 103 FPS with a minimum of 88 FPS and maximum of 119 FPS, High produces 91 FPS, and Ultra produces 74 FPS. The 39 FPS spread between Low and Ultra shows that the GPU's fill rate and shading capabilities are the primary constraints at 4K. The minimum frame rate of 88 FPS at Medium settings ensures that even the most complex scenes remain playable, but the Ultra preset's 74 FPS average approaches the threshold where frame drops become noticeable.

The data reveals interesting scaling patterns. Moving from 1080p to 1440p at Low settings costs 100 FPS (301 to 201), while moving from 1440p to 4K at Low costs 88 FPS (201 to 113). This suggests that the GPU's pixel rate becomes increasingly taxed as resolution increases, with the 4K workload requiring roughly four times the pixel throughput of 1080p.

CPU Role

The Intel Core i7-13700K serves as a formidable partner for the RX 5700 XT in Roblox, with its 16 cores and 24 threads providing ample processing power for the game's physics and scripting systems. The CPU's boost clock of 5.40 GHz and base clock of 3.40 GHz, combined with a 30 MB shared L3 cache, ensure that draw calls and game logic are processed with minimal latency. The CPU's 89th percentile ranking among all processors indicates that it is well above average for this workload.

The CPU's benchmark scores demonstrate its capability to handle Roblox's single-threaded aspects. The Cinebench R23 single-core score of 2116 and Geekbench single-core score of 2529 show strong single-thread performance, which is critical for Roblox's primary game logic thread. The multi-threaded scores, including Cinebench R23 multi-core of 30745 and Passmark multithread of 45887, provide substantial headroom for the game's parallel tasks, such as physics simulation and network processing.

In the context of this combo, the CPU is rarely the bottleneck. The frame rate scaling with resolution confirms this, as the CPU's performance remains constant while the GPU's workload increases. At 1080p, the CPU could theoretically push even higher frame rates if the GPU were faster, as the 301 FPS at Low settings does not approach the CPU's maximum throughput. The data suggests that the CPU's 24 threads are more than sufficient for Roblox's multithreaded tasks, and the 30 MB L3 cache helps keep frequently accessed game data close to the cores.

The CPU's memory support for DDR4 and DDR5 with a dual-channel bus ensures that the memory subsystem does not introduce latency bottlenecks. The 125 W TDP and Intel Socket 1700 platform provide a stable foundation for sustained performance, though the CPU's power demands are modest compared to its computational output.

How This Combo Ranks

The Intel Core i7-13700K and AMD Radeon RX 5700 XT combination ranks 2750th out of 3711 tested combos in Roblox. This position places it in the 74th percentile, meaning it outperforms 74% of all tested configurations. Given the GPU's age — it was released in July 2019 and is now end-of-life — this ranking is impressive, though it reflects the fact that Roblox is not a graphically demanding title.

The CPU's nearest rivals provide context for its performance. The i7-13700K has an average benchmark score of 46881, which is 0.2% lower than the AMD Ryzen 9 5900 (46971) and 0.3% lower than the AMD Ryzen AI 9 HX PRO 375 (47022). However, it outperforms the AMD Ryzen 9 7845HX and Intel Xeon w3-2535 by 0.5% each. These small deltas indicate that the CPU is well-matched against its peers in synthetic benchmarks.

The GPU's nearest rivals show a similar pattern. The RX 5700 XT has an average benchmark score of 16361, which is 0.1% higher than the AMD Radeon Pro 5600M (16351) but 0.3% lower than the NVIDIA RTX PRO 6000 Blackwell (16408) and AMD Radeon PRO W7500 (16415). The delta of 0.9% versus the NVIDIA GeForce RTX 5090 D V2 (16504) is the largest gap, but all rivals are within 1% of each other, indicating that the GPU's performance tier is tightly clustered.

The combo's ranking of 2750 suggests that while the individual components are mid-range or better, the pairing does not reach the top tiers of Roblox performance. This is likely due to the GPU's RDNA 1.0 architecture lacking the efficiency of newer designs, even though the CPU provides ample support. The data implies that upgrading the GPU would yield significant improvements in Roblox, particularly at 4K where the GPU is the clear bottleneck.
