# Roblox Performance Analysis: Intel Core Ultra 9 290K Plus + NVIDIA GeForce RTX 5070

The Intel Core Ultra 9 290K Plus paired with the NVIDIA GeForce RTX 5070 delivers exceptional performance in Roblox, ranking 603rd out of 3010 tested combos for this game. This places the combo in the top 20% of all tested configurations, which is impressive given that Roblox is a lightweight sandbox title that tends to be more sensitive to single-thread CPU performance than raw GPU throughput. The data shows a system capable of maintaining triple-digit frame rates even at 4K Ultra settings, with the RTX 5070’s 12 GB of GDDR7 memory and the Core Ultra 9 290K Plus’s 24 cores working together to crush what is typically a modest workload. The following analysis breaks down exactly how each component contributes to the measured results, where the bottlenecks lie, and which settings provide the best experience across the three tested resolutions.

How This Combo Ranks

The combo’s rank of 603 out of 3010 tested combinations places it well above the median, with roughly 80% of all tested systems falling behind it in Roblox performance. This is a strong showing, especially considering that Roblox is not typically a demanding title that would stress high-end hardware. The ranking suggests that the combination of the Core Ultra 9 290K Plus and RTX 5070 is well-balanced for this game, with neither component dragging the other down. The CPU’s percentile ranking of 96 among all tested CPUs indicates that it outperforms 96% of processors, while the GPU’s percentile of 82 among all GPUs shows it beats 82% of graphics cards. The fact that the CPU ranks higher than the GPU in their respective fields hints that Roblox is somewhat CPU-bound at lower resolutions, which becomes evident when examining the FPS scaling across settings.

When looking at the CPU’s nearest rivals, the Core Ultra 9 290K Plus scores an average benchmark score of 84003, which is just 0.2% ahead of the Intel Core Ultra 9 285K’s 83807. That is a negligible difference, effectively placing these two processors at parity in synthetic tests. Against the AMD EPYC 4584PX, the lead widens to 1.1% (83090), and against the AMD EPYC 9135, it is 1.2% (82980). Interestingly, the AMD EPYC 7F72 scores higher at 85072, meaning the Core Ultra 9 290K Plus trails that specific EPYC part by 1.3%. These are all server-class chips, so the margins are small, but the data shows the Core Ultra 9 290K Plus sits comfortably in the upper echelon of CPU performance. For Roblox specifically, the single-core performance matters most, and with a Cinebench R23 single-core score of 7303, the CPU is clearly capable of feeding the GPU at high frame rates.

The GPU’s rivals tell a different story. The RTX 5070’s average benchmark score of 40377 is nearly identical to the AMD Radeon Pro 580’s 40318, a difference of just 0.1%. It also edges out the AMD Radeon Pro WX 7100 by 0.8% (40063) and the NVIDIA RTX A500 Mobile by 2% (39568), while trailing the AMD Radeon Pro 5300 by 1.2% (40870). These are professional workstation GPUs, not gaming cards, which makes the comparison somewhat unusual but still valid for ranking purposes. What matters for Roblox is that the RTX 5070’s 82nd percentile ranking among all GPUs is more than sufficient, as the measured FPS data demonstrates. The combo’s overall rank of 603 out of 3010 suggests that while there are many faster systems, this particular pairing is far more than adequate for Roblox, delivering frame rates that exceed what most displays can even show.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture with a GB205 chip fabricated on a 5 nm process at TSMC. It packs 6144 shading units, 192 texture mapping units, and 80 raster output units, along with 48 ray tracing cores and 192 tensor cores. The GPU’s base clock runs at 2325 MHz with a boost clock of 2512 MHz, while memory operates at 1750 MHz (28 Gbps effective). The 12 GB of GDDR7 memory sits on a 192-bit bus, providing a memory bandwidth of 672.0 GB/s. For a game like Roblox, which has relatively simple geometry and textures, this memory configuration is overkill in the best way possible—it means texture streaming and asset loading are never bottlenecks.

The GPU’s measured performance in Roblox is remarkably strong. At 1080p Low settings, the RTX 5070 pushes an average of 537 FPS, which is likely near the game’s engine limits. Even at 4K Ultra, the card maintains 132 FPS average, showing that it has ample headroom for this title. The GPU’s pixel rate of 201.0 GPixel/s and texture rate of 482.3 GTexel/s are far beyond what Roblox demands, so the card spends most of its time waiting on the CPU rather than working at full capacity. This is particularly evident when comparing 1080p Low (537 FPS) to 1080p Ultra (350 FPS)—the drop of 187 FPS from raising settings is substantial but still leaves the system well above any playable threshold.

The RTX 5070’s 12 GB VRAM is worth noting because Roblox can occasionally balloon in memory usage with user-generated content, but the measured data shows no signs of VRAM-related slowdowns. The card’s FP32 performance of 30.87 TFLOPS and FP16 of 30.87 TFLOPS (1:1) are more than enough for the shader work Roblox requires. The GPU also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which means it can handle any rendering path Roblox might use. The 3DMark Steel Nomad DX12 score of 5077 and PassMark G3D score of 29137 confirm the card’s overall strength, though these synthetic benchmarks are far heavier than Roblox’s actual workload. In practice, the RTX 5070’s role in this combo is to ensure that even the most complex Roblox experiences—with dense environments, many players, and custom effects—run smoothly at any resolution up to 4K.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor from the Core Ultra Series 2, codenamed Arrow Lake Refresh. It has a base clock of 3.70 GHz and a boost clock of 5.80 GHz, with 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. The CPU is built on a 3 nm process at TSMC, with 17,800 million transistors on a 243 mm² die. Memory support is DDR5 via a dual-channel interface with a bandwidth of 115.2 GB/s. For Roblox, the most critical specification is the single-thread performance, since the game typically relies on a primary thread for most of its simulation logic. The CPU’s Cinebench R23 single-core score of 7303 is excellent, and its PassMark single-thread score of 4823 reinforces that this is a top-tier processor for lightly threaded workloads.

The CPU’s multi-threaded capabilities are equally impressive, with a Cinebench R23 multi-core score of 51731 and a PassMark multithread score of 60860. However, Roblox does not scale well across many cores, so the 24 threads are largely underutilized in this game. The data reflects this: at 1080p Low, the system hits 537 FPS average, which is a frame rate that typically requires very strong single-core performance. The boost clock of 5.80 GHz is likely the key factor here, as it allows the CPU to process game logic and physics calculations with minimal latency. The 36 MB of L3 cache also helps by keeping frequently accessed data close to the cores, reducing memory stalls.

The CPU’s average benchmark score of 84003 places it at the 96th percentile of all CPUs, and its nearest rivals are all within a narrow band of performance. The 0.2% lead over the Core Ultra 9 285K is essentially a tie, while the 1.1% and 1.2% leads over the AMD EPYC parts are also minor. This tells us that the Core Ultra 9 290K Plus is not dramatically faster than its closest competitors in synthetic tests, but for Roblox, the combination of high boost clock and efficient architecture produces real-world benefits. The CPU’s TDP of 125 W is modest for 24 cores, suggesting that thermal headroom is not a concern even in sustained gaming sessions. The integrated Arc Xe-LPG Graphics 64EU is irrelevant for this combo since the discrete RTX 5070 handles all rendering, but it does add a layer of flexibility for troubleshooting or secondary display output.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, and 3840x2160) across four settings presets (Low, Medium, High, Ultra). At 1080p, the system delivers extraordinary frame rates. Low settings produce an average of 537 FPS, Medium drops to 489 FPS, High comes in at 432 FPS, and Ultra still manages 350 FPS. The Medium preset at 1080p has recorded minimum and maximum values of 415 FPS and 562 FPS respectively, showing a tight frame time distribution with no major dips. These numbers indicate that at 1080p, the system is almost certainly CPU-limited, as even the most demanding settings cannot push the GPU to its limits.

Moving to 1440p, the frame rates remain very high but show the expected scaling. Low settings average 358 FPS, Medium delivers 326 FPS (with min/max of 277 and 375), High comes in at 288 FPS, and Ultra drops to 234 FPS. The gap between Low and Ultra at 1440p is 124 FPS, which is proportionally similar to the 187 FPS gap at 1080p. This suggests that the GPU is starting to take on more of the workload at this resolution, but the CPU still has enough headroom to keep frame rates well above 200 FPS even at Ultra. The min FPS of 277 FPS at Medium settings confirms that even the worst-case frame times are far above any playable threshold.

At 4K (3840x2160), the data shows the system beginning to shift toward GPU limitation. Low settings average 203 FPS, Medium averages 184 FPS (with min/max of 157 and 212), High drops to 163 FPS, and Ultra falls to 132 FPS. The scaling from Low to Ultra at 4K is 71 FPS, which is a smaller absolute drop than at lower resolutions but represents a larger percentage reduction (from 203 to 132 is a 35% decrease). The 4K Medium preset’s min FPS of 157 is still very smooth, and even the Ultra preset’s 132 FPS average is far above the 60 FPS target most players would consider acceptable. What is notable is that at 4K, the RTX 5070 is finally being taxed, though the 12 GB VRAM and 672.0 GB/s bandwidth ensure there are no memory-related stutters.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the system’s bottleneck characteristics. At Low settings, the system drops from 537 FPS at 1080p to 358 FPS at 1440p (a 33% reduction) and then to 203 FPS at 4K (a 43% reduction from 1440p). This progressive decline indicates that the GPU is becoming more limiting as resolution increases, but the CPU is still playing a significant role at 1080p. The fact that 1080p Low produces 537 FPS—a frame rate that exceeds most high-refresh monitors—suggests that the CPU is the primary limiter at this resolution, since the GPU could likely render even more frames if the CPU could feed it faster.

At Ultra settings, the scaling is steeper. The system goes from 350 FPS at 1080p to 234 FPS at 1440p (a 33% drop) and then to 132 FPS at 4K (a 44% drop from 1440p). The percentage drops are nearly identical to the Low settings, which is interesting because it implies that the relative load distribution between CPU and GPU does not change dramatically when moving from Low to Ultra. The GPU’s work increases with resolution and settings, but the CPU’s per-frame cost also rises with the number of draw calls and objects, even if those costs are not as visible in frame time breakdowns.

The data points to a system that is CPU-bound at 1080p, roughly balanced at 1440p, and GPU-bound at 4K. At 1080p Low, the 537 FPS average is likely near the engine’s max frame rate or the CPU’s single-thread limit. At 4K Ultra, the 132 FPS average is more reflective of the RTX 5070’s raw rasterization throughput. This means that players with high-refresh 1080p or 1440p monitors will benefit most from the CPU’s strong single-core performance, while those with 4K displays will see the GPU’s capabilities become the deciding factor. The 4K Medium preset’s 184 FPS average with a 157 FPS minimum shows that even at the highest resolution, the system never falls below a very smooth threshold.

Settings Recommendations

Based on the measured rows, the Medium preset offers the best experience across all three resolutions. At 1080p Medium, the system averages 489 FPS with a minimum of 415 FPS and maximum of 562 FPS. This is nearly indistinguishable from Low settings in terms of playability, but it provides better visual quality. At 1440p Medium, the average is 326 FPS with a minimum of 277 FPS, which is still far above any display’s refresh rate and offers a significant visual upgrade over Low. At 4K Medium, the average is 184 FPS with a minimum of 157 FPS and maximum of 212 FPS—this is the sweet spot for 4K, as it provides excellent visual fidelity while maintaining frame rates that are nearly three times the standard 60 FPS target.

High settings are also viable, particularly at 1080p and 1440p, where the system averages 432 FPS and 288 FPS respectively. At 4K High, the 163 FPS average is still excellent, but the drop from Medium’s 184 FPS represents a 11% reduction for what is likely a modest visual improvement in Roblox. Ultra settings push the system hardest, with 350 FPS at 1080p, 234 FPS at 1440p, and 132 FPS at 4K. While these numbers are all playable, Ultra’s benefits in Roblox are often subtle, and the additional load on the GPU provides little tangible improvement over Medium for most users.

For players with high-refresh monitors (240 Hz or above), the 1080p Medium preset is the clear choice, as it delivers 489 FPS average and ensures the frame rate never drops below 415 FPS, which is still above any consumer display’s refresh rate. For 1440p users, High settings at 288 FPS average offer a good balance of visual quality and performance, though Medium at 326 FPS is even safer if frame time consistency matters more. For 4K users, Medium is the recommended preset, as its 184 FPS average and 157 FPS minimum provide a smooth experience without the unnecessary load of Ultra. Low settings are only recommended for competitive play where maximum frame rates are critical, but given that even Ultra at 4K exceeds 132 FPS, the performance headroom makes Low largely unnecessary for this combo. The data clearly shows that this system is overqualified for Roblox, and the Medium preset leverages that headroom to deliver an excellent experience at any resolution.
