Roblox

Roblox is a notoriously variable title, but the measured data for the Intel Core Ultra 7 265 paired with the NVIDIA GeForce GTX 1070 provides a clear picture of a system that is overwhelmingly GPU-limited at higher resolutions, yet surprisingly capable at 1080p. The dataset reveals a performance curve that degrades predictably with resolution, but the delta between settings presets narrows significantly as pixel count rises, indicating where the bottleneck shifts.

Resolution Scaling

The measured FPS data shows a steep and consistent decline as resolution increases from 1920x1080 to 3840x2160. At 1080p with Low settings, the combo averages 252 FPS. Moving to 1440p drops that to 168 FPS, a 33% reduction. At 4K, the same Low preset yields 95 FPS, which is 62% lower than the 1080p result. This scaling pattern is typical of a system where the GPU becomes the limiting factor; the CPU has ample headroom at lower resolutions, but the GTX 1070's rendering throughput caps the frame rate as pixel count multiplies.

The gap between 1080p and 1440p is substantial across all presets, but the jump from 1440p to 4K is even more punishing. For High settings, the drop from 203 FPS at 1080p to 135 FPS at 1440p is a 33% loss, and then falling to 77 FPS at 4K is another 43% reduction. This non-linear scaling suggests that at 4K, the GPU is operating at its absolute limit, with the memory bandwidth of 256.3 GB/s and the 8 GB GDDR5 frame buffer becoming critical constraints. The 4K Ultra preset, at 62 FPS, is the only configuration that dips below the 60 FPS threshold, indicating that this resolution is only viable for lower fidelity settings.

Interestingly, the performance delta between Low and Ultra presets shrinks as resolution rises. At 1080p, the spread is 87 FPS (252 Low vs 165 Ultra). At 1440p, the spread narrows to 58 FPS (168 Low vs 110 Ultra). At 4K, it further compresses to 33 FPS (95 Low vs 62 Ultra). This compression is a classic sign of GPU saturation—at 4K, the pixel throughput demand is so high that the GPU is the bottleneck regardless of the graphical complexity of the scene, making the preset choice less impactful on frame rate than at lower resolutions where the CPU can feed frames faster.

CPU Role

The Intel Core Ultra 7 265 is a 20-core, 20-thread processor based on the Arrow Lake architecture, with a base clock of 2.40 GHz and a boost clock of 5.30 GHz. Its benchmark data shows strong multi-threaded performance, with a Cinebench R23 multi-core score of 42,216 and a single-core score of 5,960. The PassMark single-thread score of 4,689 further confirms solid per-core performance, which is critical for Roblox since the game's engine does not scale perfectly across many cores.

In this specific pairing, the CPU's role is primarily to feed the GPU without becoming a bottleneck at lower resolutions. The data supports this: at 1080p Low, the system achieves 252 FPS, which is far above what most monitors can display, and this is only possible because the CPU can issue draw calls and physics updates faster than the GPU can rasterize. The 30 MB of shared L3 cache and 102.4 GB/s of dual-channel DDR5 memory bandwidth provide adequate data throughput for the game's blocky geometry and simple textures.

However, the CPU's headroom is not unlimited. At 4K, the frame rates drop to between 62 and 95 FPS, but this is not due to the CPU being inadequate—rather, it is the GPU hitting its pixel fill limits. The CPU's PassMark physics score of 2,923 and data compression score of 522,983 suggest it can handle complex game logic, but Roblox's procedural generation and user-created content can sometimes create single-threaded spikes. The single-core Cinebench R23 result of 5,960 is robust, ensuring that even poorly optimized game scripts do not cause catastrophic frame drops, as evidenced by the 4K Medium minimum FPS of 74, which is only 13 FPS below its average.

Settings Recommendations

Based on the measured rows, the Medium preset appears to be the optimal balance between visual fidelity and performance for this combo. At 1080p Medium, the system averages 230 FPS with a minimum of 195 FPS, which is exceptionally smooth for any display. At 1440p Medium, the average drops to 153 FPS with a minimum of 130 FPS, still well above the 120 Hz refresh rate common on many gaming monitors. Even at 4K Medium, the average of 87 FPS with a minimum of 74 FPS is playable, though it requires a VRR display to avoid tearing.

The High preset is a reasonable alternative for users who prioritize visual quality, as it only costs a 10-12% performance penalty over Medium at each resolution (203 vs 230 FPS at 1080p, 135 vs 153 FPS at 1440p, 77 vs 87 FPS at 4K). The Ultra preset, however, is harder to recommend. At 4K, it drops to 62 FPS, which is marginal for fast-paced games, and at 1440p it falls to 110 FPS, which is still playable but offers diminishing returns over High for the extra GPU load. For the best experience on this hardware, Medium is the sweet spot; it maintains a minimum FPS above 70 at all resolutions tested, ensuring no noticeable stutter.

How This Combo Ranks

The combo ranks 2,474 out of 3,010 tested combinations in Roblox, placing it in the 18th percentile of all systems. This is a surprisingly low rank for a pairing that includes a high-end 2025 CPU and a mid-range 2016 GPU. The ranking reflects that Roblox is heavily GPU-bound in the dataset, and the GTX 1070's age holds the system back despite the modern CPU. The GPU's percentile versus all GPUs is 47, meaning it sits near the median of all graphics cards, but the CPU's percentile is 93, indicating it is in the top 7% of all processors. This mismatch confirms that the combo is not balanced for this game; the CPU is overqualified relative to the GPU.

Comparing the CPU to its nearest rivals, the Intel Core Ultra 7 265 has an average benchmark score of 64,640, which is 0.3% lower than the AMD EPYC 4464P (64,823) and 0.7% lower than the AMD EPYC 7343 (64,202). It outperforms the Intel Core Ultra 7 265F by 0.3% and the AMD EPYC 9124 by 0.7%. These are all server-class processors, indicating that the Ultra 7 265 is a capable workstation chip, but in Roblox, this raw compute power does not translate to a high combo ranking because the game's frame rate is dictated by the GPU. The GPU's nearest rivals show a tight cluster: the NVIDIA Quadro M2000M is 0.5% faster, the AMD FirePro W5000 is 0.2% faster, while the NVIDIA Tesla M10 and Tesla C2070 are 0.6% and 0.7% slower, respectively. This suggests the GTX 1070 is performing exactly as expected, but those expected performance levels are just not high enough for a top-tier Roblox ranking.

GPU Role

The NVIDIA GeForce GTX 1070 is built on the Pascal architecture with 1,920 shading units and 64 ROPs. Its boost clock of 1,683 MHz and base clock of 1,506 MHz are modest by modern standards, but the 8 GB of GDDR5 memory on a 256-bit bus provides 256.3 GB/s of bandwidth. The measured data shows this GPU is the primary constraint at resolutions above 1080p. The 4K results, ranging from 62 to 95 FPS, are consistent with a card that was designed for 1440p gaming, not 4K. The pixel rate of 107.7 GPixel/s and texture rate of 202.0 GTexel/s are sufficient for Roblox's low-poly aesthetic, but the sheer number of pixels at 4K overwhelms the shading units.

The GPU's FP32 performance of 6.463 TFLOPS is adequate for the game's simple shaders, but the lack of ray tracing cores and tensor cores means it relies entirely on rasterization. The PassMark G3D score of 13,498 places it in the 47th percentile of all GPUs, confirming its mid-range status. Interestingly, the GPU's DirectX 12 PassMark score of 48 is very low, but Roblox primarily uses DirectX 11, where the score is 100, indicating better optimization for the game's API. The 8 GB VRAM is not a limiting factor in Roblox, as the game's textures are small, but the memory bandwidth becomes critical at 4K where the frame buffer must be filled faster. The 4K Medium minimum FPS of 74 suggests the GPU can sustain playable performance, but the Ultra preset's 62 FPS average indicates it is at the edge of its capabilities.
