# Roblox with Intel Core i5-13400F + AMD Radeon RX 7700 — Benchmark Analysis

The Intel Core i5-13400F paired with the AMD Radeon RX 7700 delivers exceptionally high frame rates in Roblox, ranking 1341st out of 3010 tested combinations. This places the configuration in the 55th percentile of all combos, indicating solid mid-pack performance. The data shows a system that is overwhelmingly GPU-limited at lower resolutions, with the CPU becoming a more significant factor only at 1080p where frame rates approach 400 FPS. The Radeon RX 7700's 16 GB of VRAM and 256-bit memory bus provide ample headroom for Roblox's modest graphical demands, while the i5-13400F's 10 cores and 16 threads handle the game's single-threaded physics and scripting workloads with considerable ease.

Resolution Scaling

The measured frame rates reveal a clear pattern of diminishing returns as resolution increases, but the absolute numbers remain high throughout. At 1080p with Low settings, the system produces 386 FPS average; at 1440p this drops to 258 FPS, and at 4K it falls further to 146 FPS. This represents a 62% reduction from 1080p to 4K at Low settings, indicating that the GPU is the primary limiting factor at higher resolutions. The scaling from 1440p to 4K shows a 43% performance drop, which is consistent with a GPU-bound scenario where pixel count increases by 125% but frame rate only decreases by less than half.

The Medium settings row provides the most complete dataset, including minimum and maximum frame rates. At 1080p Medium, the average is 352 FPS with a minimum of 299 FPS and maximum of 404 FPS. Moving to 1440p Medium, the average drops to 235 FPS with a minimum of 199 FPS and maximum of 270 FPS. At 4K Medium, the average is 133 FPS with a minimum of 113 FPS and maximum of 153 FPS. The tight min-max spread at each resolution suggests consistent frame pacing without major stutters, and the 33% reduction from 1080p to 1440p at Medium settings is proportionally similar to the Low settings scaling.

The High settings row shows a similar pattern: 311 FPS at 1080p, 207 FPS at 1440p, and 117 FPS at 4K. This represents a 62% drop from 1080p to 4K, identical to the Low settings scaling. Ultra settings produce 252 FPS at 1080p, 168 FPS at 1440p, and 95 FPS at 4K — a 62% reduction from 1080p to 4K as well. The consistent 62% scaling across all settings presets indicates that the GPU's rendering load scales linearly with resolution, and the RX 7700's 16 GB VRAM capacity is never a bottleneck even at 4K Ultra, where the average of 95 FPS remains well above the 60 FPS threshold for smooth gameplay.

Settings Recommendations

For 1080p displays, the data suggests that Ultra settings at 252 FPS average provide an excellent experience without any meaningful compromise. The jump from High to Ultra costs 59 FPS (from 311 to 252), a 19% reduction, but the absolute frame rate remains far above what any display can show. Even the minimum frame rate at 1080p Medium (299 FPS) exceeds the refresh rate of all but the most extreme gaming monitors. At 1080p, users should select Ultra settings for maximum visual fidelity, as the performance headroom is substantial.

At 1440p, the choice becomes more nuanced. Ultra settings deliver 168 FPS average, which is still exceptionally smooth for most displays. The difference between High (207 FPS) and Ultra (168 FPS) is 39 FPS, or 19% — the same proportional cost as at 1080p. Given that 1440p Ultra maintains frame rates well above 144 Hz, the recommended setting is Ultra for users with standard 144 Hz monitors. However, for those with 240 Hz displays, High settings at 207 FPS would be the better choice to fully utilize the refresh rate.

At 4K, the data shows that Ultra settings (95 FPS) remain playable and smooth, but Medium (133 FPS) offers a 40% performance improvement with only a modest visual quality reduction. The 4K Medium row is the only one with recorded minimum and maximum values (113 and 153 FPS respectively), indicating that even the minimum frame rate stays above 100 FPS. For 4K gaming, Medium or High settings provide the best balance, with High at 117 FPS being the recommended choice for users who prioritize visual quality while maintaining a comfortable margin above 60 FPS. The 4K Ultra setting at 95 FPS is acceptable but leaves less headroom for complex scenes or multiplayer instances.

GPU Role

The AMD Radeon RX 7700 features 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of bandwidth. This memory configuration is more than sufficient for Roblox, which is not a VRAM-intensive title. The GPU's 2560 shading units, 160 texture mapping units, and 96 render output units are all well-utilized at higher resolutions, as evidenced by the consistent resolution scaling patterns. The boost clock of 2459 MHz and game clock of 2041 MHz contribute to the GPU's ability to maintain high frame rates across all tested settings.

The RX 7700's benchmark scores place it in the 58th percentile of all GPUs, with an average benchmark score of 15852. Its nearest rivals include the AMD Radeon R9 370X (deltaPct -0.1%), the AMD Radeon RX 9060 (deltaPct -1%), the AMD Radeon Pro W5500 (deltaPct 1.1%), and the NVIDIA GeForce RTX 3060 Ti (deltaPct -1.7%). These close margins indicate that the RX 7700 performs comparably to these cards in synthetic benchmarks, but the measured FPS in Roblox shows the GPU is clearly capable of delivering high frame rates at all resolutions.

The GPU's 40 ray tracing cores and RDNA 3.0 architecture support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. While Roblox does not heavily utilize ray tracing, the modern feature set ensures compatibility with future updates. The 5 nm process node from TSMC, with 28,100 million transistors on a 346 mm² die, provides efficient operation with a 200 W TDP. The dual-slot design with two 8-pin power connectors and a suggested 550 W PSU indicates the card is not overly power-hungry, and the 267 mm length makes it compatible with most mid-tower cases.

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression across settings. Low settings produce 386 FPS average, Medium settings produce 352 FPS (with a minimum of 299 FPS and maximum of 404 FPS), High settings produce 311 FPS, and Ultra settings produce 252 FPS. The gap between Low and Ultra is 134 FPS, representing a 35% reduction. The Medium settings row provides the only min-max data at 1080p, with a spread of 105 FPS between minimum and maximum, indicating some scene-to-scene variance but no problematic stutters.

At 2560x1440, the frame rates remain high but show the expected resolution penalty. Low settings deliver 258 FPS average, Medium settings deliver 235 FPS (minimum 199 FPS, maximum 270 FPS), High settings deliver 207 FPS, and Ultra settings deliver 168 FPS. The difference between Low and Ultra at 1440p is 90 FPS, a 35% reduction — identical to the 1080p proportional gap. The Medium settings min-max spread is 71 FPS, which is narrower than at 1080p, suggesting more consistent performance at the higher resolution.

At 3840x2160, the system still maintains excellent frame rates. Low settings produce 146 FPS average, Medium settings produce 133 FPS (minimum 113 FPS, maximum 153 FPS), High settings produce 117 FPS, and Ultra settings produce 95 FPS. The gap between Low and Ultra is 51 FPS, again a 35% reduction. The Medium settings min-max spread at 4K is 40 FPS, the tightest of all resolutions, indicating that the GPU workload is more consistent at 4K. Across all resolutions and settings, the system never drops below 95 FPS average, demonstrating that this configuration is overkill for Roblox's graphical requirements.
