Roblox

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor from the Core Ultra Series 2 family, built on the Arrow Lake Refresh architecture and fabricated on TSMC's 3 nm process node. It operates with a base clock of 3.70 GHz and reaches a boost clock of 5.80 GHz, with a 125 W TDP. The CPU features a three-tier cache hierarchy: 192 KB of L1 cache per core, 3 MB of L2 cache per core, and a shared 36 MB L3 cache. This large core count and high boost clock position the processor in the 96th percentile among all CPUs in the benchmark database, indicating it outperforms the vast majority of processors tested.

In the context of Roblox, a sandbox game that often relies on single-thread performance for physics and game logic, the CPU's boost clock of 5.80 GHz is the more relevant specification than the raw core count. The processor's single-core performance is demonstrated by its Cinebench R23 single-core score of 7303 and its Passmark single-thread score of 4823. These figures show that the CPU can handle the game's primary thread workload with substantial headroom. Multi-core performance is also exceptional, with a Cinebench R23 multi-core score of 51731 and a Passmark multithread score of 60860, though Roblox typically does not scale well beyond a few threads.

The CPU's nearest rival in average benchmark score is the Intel Core Ultra 9 285K, which scores 83807 on average, a mere 0.2% behind the 290K Plus's average of 84003. This near-identical performance means the 290K Plus offers no meaningful advantage over its direct predecessor in synthetic benchmarks. Other close rivals include the AMD EPYC 4584PX and AMD EPYC 9135, with scores of 83090 and 82980 respectively, placing them 1.1% and 1.2% behind. The only rival that scores higher is the AMD EPYC 7F72 at 85072, which is 1.3% ahead. These margins are negligible in real-world gaming, confirming that the CPU is not the limiting factor in the measured FPS results.

The CPU's memory bandwidth of 115.2 GB/s over a dual-channel DDR5 bus is ample for Roblox's modest memory demands. The processor also includes integrated Arc Xe-LPG Graphics 64EU, though the system uses a discrete GPU. With 20 PCIe Gen 5 lanes, the CPU has more than enough bandwidth to feed the Radeon RX 580, which operates on PCIe 3.0 x16. For Roblox, the data shows that the CPU's high single-thread performance ensures it can maintain frame delivery even at lower settings where the GPU might otherwise become the bottleneck.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 580 is a Polaris 20 chip built on GCN 4.0 architecture, manufactured on GlobalFoundries' 14 nm process. It features 8 GB of GDDR5 memory on a 256-bit bus, delivering 256.0 GB/s of memory bandwidth. The GPU operates at a base clock of 1257 MHz and a boost clock of 1340 MHz, with memory running at 2000 MHz (8 Gbps effective). The card has 2304 shading units, 144 texture mapping units, and 32 raster operations pipelines, producing a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s. Its FP32 performance is rated at 6.175 TFLOPS, and it supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3.

The RX 580 is positioned in the 53rd percentile among all GPUs in the database, with an average benchmark score of 12928. Its nearest rival is the NVIDIA GeForce RTX 3050 Ti Mobile, which scores 12940, a negligible 0.1% difference. The NVIDIA GeForce GTX 1660 SUPER scores 12986, trailing by 0.4%, while the AMD Radeon 740M and AMD FirePro W5100 score 12870 and 12847, sitting 0.5% and 0.6% behind respectively. This clustering indicates the RX 580 delivers performance comparable to mid-range GPUs from around the same era, though all are within 1% of each other in synthetic benchmarks.

For Roblox, the GPU's 8 GB VRAM is more than sufficient for the game's textures and assets, even at 4K resolution. The measured FPS data confirms that the GPU is the primary performance limiter in this combination, as frame rates vary significantly across settings and resolutions. At 1920x1080, the RX 580 delivers 164 FPS on Low settings, which drops to 107 FPS on Ultra. At 3840x2160, the same settings spread yields 62 FPS on Low and 40 FPS on Ultra. This scaling pattern is typical of a GPU-bound scenario, where higher settings increase pixel and shading workload.

The RX 580's boost clock of 1340 MHz and 256.0 GB/s bandwidth are adequate for Roblox's relatively simple geometry and lighting. The GPU's DirectX 11 Passmark score of 60 and DirectX 12 score of 43 indicate the card handles modern APIs, though Roblox is known to use older rendering paths. The Vulkan score of 45173 in Geekbench suggests strong compute performance for a card of this generation. The GPU's 185 W TDP and suggested 450 W PSU are consistent with its mid-range positioning, and its 6.175 TFLOPS FP32 throughput is sufficient for the game's shader complexity.

FAQ

Q: What is the best resolution for this CPU-GPU combo in Roblox?

A: The data shows 1920x1080 provides the most consistent experience. At 1080p, even Ultra settings yield 107 FPS, while Low reaches 164 FPS. At 2560x1440, Ultra drops to 71 FPS, and at 3840x2160, Ultra falls to 40 FPS. The 1080p resolution keeps all settings above the 100 FPS threshold except Ultra, which still maintains a playable 107 FPS.

Q: How does the RX 580 compare to its closest GPU rivals?

A: The RX 580's average benchmark score of 12928 is within 0.6% of all four nearest rivals.

These differences are within measurement noise, meaning the RX 580 performs essentially on par with these alternatives.

Q: Is the Intel Core Ultra 9 290K Plus overkill for Roblox?

A: The CPU's 96th percentile ranking and single-core score of 7303 in Cinebench R23 suggest it has far more processing power than Roblox requires. The game's measured FPS is consistently limited by the GPU, as evidenced by the large FPS drops with higher settings. The CPU's 24 cores and 5.80 GHz boost clock provide substantial headroom, but this does not translate to higher frame rates in Roblox since the GPU is the bottleneck.

Q: What is the FPS difference between Low and Ultra settings at 1080p?

A: At 1920x1080, Low settings deliver 164 FPS average, Medium delivers 149 FPS, High delivers 132 FPS, and Ultra delivers 107 FPS. This represents a 57 FPS drop (34.8%) from Low to Ultra. The Medium setting has a measured min FPS of 127 and max FPS of 172, showing some variance, while other settings have no min/max data recorded.

Q: How does this combo rank among all tested combinations?

A: This combination ranks 2756 out of 3010 tested combos in Roblox. This places it in the lower portion of the database, reflecting the RX 580's mid-range GPU performance relative to more powerful modern combinations, despite the high-end CPU. The rank indicates that while the CPU is top-tier, the GPU limits the overall system's Roblox performance.

Q: Can this system handle 4K gaming in Roblox?

A: At 3840x2160, the combo delivers playable frame rates on most settings. Low averages 62 FPS, Medium averages 56 FPS with a min of 48 and max of 65, High averages 50 FPS, and Ultra averages 40 FPS. While all settings are technically playable, only Low and Medium maintain frame rates above 50 FPS, making 4K viable only with reduced settings.

Settings Recommendations

The measured FPS data provides clear guidance on the optimal settings for each resolution. At 1920x1080, the Medium preset delivers the best balance of visual quality and performance. The Medium setting averages 149 FPS, which is 15 FPS higher than High (132 FPS) and 42 FPS higher than Ultra (107 FPS). The Medium setting also records a minimum FPS of 127 and maximum of 172, indicating smooth frame delivery without significant dips. The jump from Low (164 FPS) to Medium (149 FPS) costs only 15 FPS while providing noticeably better visuals, making Medium the sweet spot.

At 2560x1440, the Medium preset again proves optimal. It averages 100 FPS with a minimum of 85 and maximum of 115, keeping frame rates comfortably above the 60 FPS threshold. High settings average 88 FPS, which is still acceptable, while Ultra drops to 71 FPS. The Low setting at 1440p averages 110 FPS, but the visual trade-off is unnecessary given that Medium maintains triple-digit performance. The 15 FPS difference between Low and Medium at this resolution is small relative to the visual improvement.

At 3840x2160, the situation changes due to GPU limitations. The Low preset averages 62 FPS, Medium averages 56 FPS, High averages 50 FPS, and Ultra averages 40 FPS. The Medium preset provides the best experience here because it sustains a 56 FPS average and never dips below 48 FPS, while High and Ultra fall below the 60 FPS threshold more frequently. Given that Roblox is not a graphically demanding title, the Medium preset at 4K offers acceptable performance, though players seeking higher frame rates should prefer 1440p.

The data indicates that the Medium preset is the recommended choice across all three resolutions. It consistently delivers the best compromise between frame rate and visual fidelity, and it is the only setting that records minimum and maximum FPS values across all resolutions, suggesting more stable frame pacing. The Ultra preset is only advisable at 1080p, where it still achieves 107 FPS, but the 42 FPS penalty compared to Medium is substantial for marginal visual gains.

How This Combo Ranks

This combination of the Intel Core Ultra 9 290K Plus and AMD Radeon RX 580 ranks 2756 out of 3010 tested combos in Roblox. This places the system in the lower 8.4% of all combinations tested, which initially seems paradoxical given the CPU's high-end positioning. The ranking is predominantly influenced by the GPU's mid-range performance, as the RX 580 sits in the 53rd percentile among all GPUs, while the CPU ranks in the 96th percentile. The combination's overall performance is therefore constrained by the slower component, which is typical for gaming systems.

The rank of 2756 indicates that most other tested combinations deliver higher average FPS in Roblox. This is expected, as the RX 580 is an older GPU (released in 2017) with a modest 6.175 TFLOPS of FP32 performance, while many other combos in the database will use newer or higher-tier GPUs. The combo's performance is still playable, as the measured FPS data shows, but it does not compete with systems using modern mid-range or high-end GPUs.

The CPU's contribution to the ranking is minimal, as Roblox's performance is dictated by the GPU in this system. The 290K Plus's 24 cores and 5.80 GHz boost clock provide no additional frame rate benefit beyond what a less powerful CPU would offer in this scenario. The data confirms that the CPU is not a bottleneck, as the FPS scales inversely with graphics settings, a hallmark of GPU-limited performance. The combo rank reflects this imbalance: a top-tier CPU paired with a mid-range GPU yields a system that ranks below average in this game.

For context, the CPU alone outperforms 96% of all processors, and its nearest rivals are within 1.3% of its average score. The GPU alone outperforms 53% of all GPUs, with rivals all within 0.6% of its score. The system's rank of 2756 out of 3010 shows that the GPU's percentile positioning is the dominant factor in determining Roblox performance, as the game is not CPU-intensive. Users seeking higher rankings would need a more powerful GPU, but the current combination still delivers acceptable frame rates at most settings.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo's performance across three resolutions and four settings presets. At 1920x1080, the system delivers the highest frame rates. The Low preset averages 164 FPS, the Medium preset averages 149 FPS with a minimum of 127 and maximum of 172, the High preset averages 132 FPS, and the Ultra preset averages 107 FPS. The spread from Low to Ultra is 57 FPS, representing a 34.8% reduction in performance when moving to the highest settings. The Medium preset's recorded minimum of 127 FPS ensures that even the most demanding scenes stay well above the 60 FPS threshold.

At 2560x1440, the frame rates remain robust but show the expected decline from 1080p. The Low preset averages 110 FPS, Medium averages 100 FPS with a minimum of 85 and maximum of 115, High averages 88 FPS, and Ultra averages 71 FPS. The delta between Low and Ultra is 39 FPS, a 35.5% reduction. The Medium preset again provides the most stable experience, with its minimum of 85 FPS keeping frame times consistent. The Ultra preset at 71 FPS is still playable, but it approaches the threshold where frame pacing becomes noticeable.

At 3840x2160, the GPU becomes the limiting factor, and frame rates drop significantly. The Low preset averages 62 FPS, Medium averages 56 FPS with a minimum of 48 and maximum of 65, High averages 50 FPS, and Ultra averages 40 FPS. The difference between Low and Ultra is 22 FPS, a 35.5% reduction, consistent with the scaling seen at other resolutions. At 4K, only the Low preset maintains an average above 60 FPS, while Medium comes close at 56 FPS. The Medium preset's minimum of 48 FPS indicates occasional dips that may be noticeable, but the overall experience remains acceptable for a sandbox game.

Across all resolutions, the Medium preset consistently delivers the best balance of performance and stability, with recorded minimum and maximum values at every resolution. The Low preset offers the highest frame rates but sacrifices visual quality, while Ultra provides the best visuals but incurs a 35% performance penalty. The data shows that the RX 580's 8 GB VRAM and 256.0 GB/s bandwidth are sufficient for Roblox at all tested settings, with the GPU's compute throughput being the primary constraint at higher resolutions and settings.
