A: The i5-12400 shows a single-thread score of 910 in 3DMark and a max-thread score of 5,890. In Cinebench R23, the single-core score is 2,249 while multi-core reaches 15,935. The multi-thread scaling is roughly 6.5x the single-thread score in 3DMark, consistent with a 6-core/12-thread part.

# GPU Role

The AMD Radeon RX 9070 is built on the Navi 48 chip using RDNA 4.0 architecture on a 4 nm process. It carries 16 GB of GDDR6 memory on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The memory clock is listed at 2518 MHz, which translates to 20.1 Gbps effective. The GPU's base clock is 1330 MHz, with a game clock of 2070 MHz and a boost clock of 2520 MHz. These clock speeds and memory characteristics directly influence how the GPU handles Roblox's rendering load.

In Roblox, the GPU's role varies significantly with settings and resolution. At 1080p Low, the average FPS of 472.8 suggests that the GPU is barely stressed, and the frame rate is likely limited by the CPU's ability to feed draw calls. At 4K Ultra, the average FPS drops to 116.5, indicating that the GPU's shading units, texture mapping units, and render output units are now the limiting factor. The RX 9070 has 3,584 shading units, 224 TMUs, and 128 ROPs, with a pixel rate of 322.6 GPixel/s and a texture rate of 564.5 GTexel/s.

The 16 GB frame buffer is ample for Roblox, which is not a VRAM-intensive title even at 4K Ultra. The memory bandwidth of 644.6 GB/s ensures that texture streaming and asset loading do not become bottlenecks. The FP32 compute throughput of 36.13 TFLOPS is far beyond what Roblox requires, but it provides headroom for physics calculations and complex user-generated content. The GPU's 56 ray tracing cores are present but Roblox does not heavily utilize them, meaning the rasterization performance is what drives these results.

The GPU's percentile rank of 79 places it well above average, and its nearest rival comparisons show a tight cluster of scores. In the context of Roblox, the RX 9070's strengths are its high fill rates and memory bandwidth, which help maintain smooth performance at high resolutions. The data indicates that the GPU becomes the primary constraint only at 4K Ultra, where the average FPS of 116.5 still represents excellent playability.

# Resolution Scaling

The measured FPS data shows a clear pattern of resolution scaling. At 1080p Low, the combo achieves 472.8 FPS. Moving to 1440p Low drops this to 316.8 FPS, a reduction of approximately 33%. At 4K Low, the FPS falls to 177.5, which is another 44% drop from 1440p. This steep decline with resolution suggests that the CPU is the primary limiter at 1080p, but the GPU increasingly takes over as resolution rises.

For High settings, the scaling is similar but with lower absolute numbers: 380.2 FPS at 1080p, 256.6 FPS at 1440p, and 145.8 FPS at 4K. The percentage drop from 1080p to 1440p is about 32%, and from 1440p to 4K is about 43%. At Ultra settings, the pattern shifts: 309.6 FPS at 1080p, 204.8 FPS at 1440p, and 116.5 FPS at 4K. Here, the drop from 1080p to 1440p is 34%, and from 1440p to 4K is 43%.

The consistency of these percentage drops across settings indicates that resolution scaling is predictable and largely GPU-bound at higher resolutions. The difference between Low and Ultra at any given resolution is substantial: at 1080p, the gap is 472.8 FPS versus 309.6 FPS, a 53% difference. At 4K, the gap is 177.5 FPS versus 116.5 FPS, a 52% difference. This suggests that the GPU's workload scales roughly linearly with both resolution and settings.

The data shows that at 1080p, even Ultra settings exceed 300 FPS, which means the CPU is likely the limiting factor. The i5-12400's single-thread performance of 910 in 3DMark and 2,249 in Cinebench R23 is strong for a mid-range part, but Roblox's engine has known single-thread limitations. At 4K, the GPU becomes the bottleneck, as evidenced by the larger FPS drops when moving from 1440p to 4K compared to 1080p to 1440p.

# Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings yield an average of 472.8 FPS, Medium drops to 430.5 FPS, High reaches 380.2 FPS, and Ultra settles at 309.6 FPS. The spread from Low to Ultra is 163.2 FPS, showing that settings have a significant impact even at 1080p. The data reveals that the step from Low to Medium costs 42.3 FPS, Medium to High costs 50.3 FPS, and High to Ultra costs 70.6 FPS. The largest single-step penalty is between High and Ultra, indicating that Ultra settings introduce expensive effects.

At 2560x1440, the frame rates remain high but show the expected reduction. Low averages 316.8 FPS, Medium 289.2 FPS, High 256.6 FPS, and Ultra 204.8 FPS. The total spread from Low to Ultra is 112.0 FPS. The step from Low to Medium costs 27.6 FPS, Medium to High costs 32.6 FPS, and High to Ultra costs 51.8 FPS. Again, the High-to-Ultra step is the most expensive, reinforcing that Ultra settings carry a disproportionate performance cost.

At 3840x2160, the combo still maintains triple-digit frame rates. Low averages 177.5 FPS, Medium 161.7 FPS, High 145.8 FPS, and Ultra 116.5 FPS. The spread from Low to Ultra is 61.0 FPS. The step from Low to Medium costs 15.8 FPS, Medium to High costs 15.9 FPS, and High to Ultra costs 29.3 FPS. At 4K, the High-to-Ultra penalty is proportionally similar to other resolutions but smaller in absolute terms.

The data shows that the combo is capable of exceeding 300 FPS at 1080p on any setting up to High, and even Ultra stays above 300 FPS. At 1440p, all settings remain above 200 FPS. At 4K, even Ultra maintains 116.5 FPS, which is above the 60 FPS threshold commonly used as a baseline for smooth gameplay. The measurements indicate that this pairing is overkill for Roblox at standard refresh rates, but it provides ample headroom for high-refresh-rate displays.

# How This Combo Ranks

The Intel Core i5-12400 with AMD Radeon RX 9070 ranks 606th out of 1,800 tested combos in Roblox, placing it in the 66th percentile of all tested systems. This rank reflects a well-balanced pairing where the CPU and GPU complement each other without severe bottlenecks. The CPU's average benchmark score of 19,850 places it near the middle of its nearest rivals, with all deltas within 0.4% of the i7-9700, i7-8700, Ryzen Threadripper PRO 5995WX, and i5-11600K. This tight clustering suggests that CPU choices around this performance level have minimal impact on overall system ranking.

The GPU's average benchmark score of 34,780 places it at the 79th percentile among GPUs, with nearest rivals being the NVIDIA A2, Quadro GV100, Radeon HD 7970, and Radeon PRO W6400. The RX 9070 performs within 0.8% of these competitors, indicating that the GPU tier is well-established. In Roblox specifically, the combo's rank of 606 suggests that while the hardware is strong, there are 605 combos that achieve higher measured FPS. This is likely due to CPUs with higher single-thread performance, as Roblox's engine is known to be sensitive to single-thread throughput.

The data shows that this combo excels at 1080p and 1440p, where it delivers frame rates well above 200 FPS on all settings. The rank of 606 out of 1,800 means that roughly two-thirds of tested combos perform worse, but it also indicates that the top third of combos have an advantage. Given that the CPU's percentile rank is 77 and the GPU's is 79, the combined rank of 66th percentile suggests a slight underperformance relative to what the individual component percentiles might predict. This could be attributed to Roblox's specific rendering demands favoring different hardware characteristics.

The i5-12400's 6 cores and 12 threads with a boost clock of 4.40 GHz provide solid single-thread performance, as evidenced by its 3DMark single-thread score of 910 and Cinebench R23 single-core score of 2,249. These scores are competitive with the nearest rivals, but the rank indicates that some combos with higher single-thread CPUs achieve better Roblox performance. The RX 9070's 16 GB of VRAM and 644.6 GB/s bandwidth are more than sufficient for Roblox, so the GPU is unlikely to be the limiting factor in the combo's rank.
