Roblox

Roblox running on an Intel Core Ultra 7 155H paired with an NVIDIA GeForce RTX 5070 delivers frame rates that most sandbox players will never need to think about twice: 359 FPS at 1080p Low on the low end of the demand curve, and still 88 FPS at 4K Ultra on the high end. The measured data shows a pairing that is heavily graphics-limited at every resolution tested, which is exactly what you want from a combo built around a 250 W Blackwell-class card and a 28 W mobile-class processor. Below is how the numbers break down, what they say about each component, and where this combination lands in the overall ranking for this title.

Resolution Scaling

The measured averages tell a clean story. At 1920x1080, Roblox runs at 359 FPS on Low, 326 FPS on Medium, 289 FPS on High, and 234 FPS on Ultra. Step up to 2560x1440 and those figures become 239, 218, 193, and 156 FPS respectively. At 3840x2160 the same presets deliver 135, 123, 109, and 88 FPS.

The drop from 1080p to 1440p is steep: Medium loses roughly a third of its frame rate (326 to 218), High falls from 289 to 193, and Ultra slides from 234 to 156. From 1440p to 4K the decay continues at a similar rate, with Medium dropping from 218 to 123 and High from 193 to 109. When frame rate falls this consistently and this sharply as pixel count rises, the GPU is the limiting component at the upper resolutions. The RTX 5070 is being asked to push more than four times the pixels going from 1080p to 4K, and its throughput clearly determines the ceiling in each case.

The flip side is equally informative. At 1080p, the gap between Low and Ultra is 125 FPS (359 versus 234). That is a wide spread, which means the card still has headroom being consumed by visual settings even at the lowest tested resolution — the game is not pinned at a CPU cap at 1080p, or the presets would cluster tightly together. The one set of minimum and maximum figures recorded reinforces this: 1080p Medium shows a minimum of 277 and a maximum of 375 around its 326 average, a range that indicates the frame rate is still responding to scene load rather than sitting on a hard platform limit.

Practical takeaway: every resolution tested is playable at every preset. Even the worst measured cell — 4K Ultra at 88 FPS — sits comfortably above the threshold where a sandbox title feels fluid. Nobody buying or running this pairing needs to drop resolution for performance reasons in Roblox.

CPU Role

The Intel Core Ultra 7 155H is a Meteor Lake mobile processor with 16 cores and 22 threads, a 3.80 GHz base clock, a 4.80 GHz boost clock, and a 28 W TDP on the Intel BGA 2049 socket. It carries 112 KB of L1 cache per core, 2 MB of L2 per core, and a shared 24 MB L3 slice, with dual-channel DDR5 support delivering 89.6 GB/s of memory bandwidth. It is built on Intel's 7 nm process, includes Arc Xe-LPG 128EU integrated graphics, and launched as a mobile-segment part. Its launch MSRP was $503.

In synthetic terms, the chip sits in the 83rd percentile against all CPUs in the database, with an average benchmark score of 32697. Its nearest rivals are remarkably close: the Intel Core i5-14600T matches it at a delta of 0 percent, the AMD Ryzen AI 7 PRO 360 sits 0.1 percent behind, the AMD Ryzen 5 7400F is 0.2 percent ahead, and the AMD Ryzen 7 PRO 6850H is 0.4 percent ahead. In other words, the 155H performs within a fraction of a percent of a tight cluster of mid-tier competitors — a dead heat by any practical standard.

Its benchmark résumé is solid across the board: 15028 in Cinebench R23 multi-core, 1743 in R23 single-core, 8754 and 1235 in R20 multi and single, 2450 and 255 in R15 multi and single, and a PassMark multithread score of 24873 with a single-thread figure of 3468. Physics and integer math land at 1727 and 86870 respectively.

How does this map onto Roblox? A sandbox title with user-generated content is typically more sensitive to single-thread snappiness than to raw thread count, and a 1743 R23 single-core score plus a 4.80 GHz boost clock is plenty of per-core responsiveness for that workload. The 22 available threads mean background tasks — chat, streaming, browser tabs — have room to breathe without stealing cycles from the game. More importantly, the measured data shows the CPU never becomes the story here: frame rates scale down hard with resolution at every preset, which means the 155H is feeding the RTX 5070 fast enough that the GPU remains the constraint. With a 28 W TDP, this is not a chip that will sustain heavy all-core loads the way a desktop part does, but Roblox does not ask for that. The Cinebench and PassMark numbers confirm it has the headroom this game requires.

GPU Role

The NVIDIA GeForce RTX 5070 is the graphics engine of this pairing, and the data shows it is the component doing the heavy lifting. It is a Blackwell 2.0 part built on TSMC's 5 nm process around the GB205 chip, with 31,100 million transistors packed into a 263 mm² die at a density of 118.3M per mm². It runs a 2325 MHz base clock and a 2512 MHz boost clock, with 12 GB of GDDR7 on a 192-bit bus running at 1750 MHz (28 Gbps effective) for 672.0 GB/s of bandwidth.

The spec sheet lists 6144 shading units, 192 TMUs, 80 ROPs, 48 RT cores, and 192 tensor cores, producing 30.87 TFLOPS of FP32 (with FP16 at a 1:1 ratio), a pixel rate of 201.0 GPixel/s, and a texture rate of 482.3 GTexel/s. It connects over PCIe 5.0 x16, carries a 250 W TDP, uses a single 16-pin power connector, and NVIDIA suggests a 600 W PSU. Its launch MSRP was 549 USD.

Against the full GPU database, the 5070 lands in the 82nd percentile with an average benchmark score of 40377. Its listed nearest rivals — the AMD Radeon Pro 580 at 0.1 percent behind, the AMD Radeon Pro WX 7100 at 0.8 percent behind, the AMD Radeon Pro 5300 at 1.2 percent ahead, and the NVIDIA RTX A500 Mobile at 2 percent behind — confirm it as an upper-tier card, not a halo product. Its synthetic results back that up: 5077 in 3DMark Steel Nomad, 178923 in Geekbench Vulkan, 172660 in Geekbench OpenCL, and 29137 in PassMark G3D.

For Roblox specifically, the relevant numbers are bandwidth and pixel throughput. The 672.0 GB/s of GDDR7 bandwidth explains why 4K remains so playable: at 3840x2160 Medium the card still averages 123 FPS, with a recorded band of 105 minimum to 142 maximum. The 12 GB frame buffer is far more capacity than this title demands, so VRAM pressure is a non-issue at any tested resolution. Meanwhile, the strong Low-to-Ultra spread at 1080p (359 to 234) shows the card's shading and texture resources are genuinely being used by the higher presets rather than idling behind a CPU limit. If there is a caveat, it is that a game of this type cannot extract everything a 5070 offers — the frame rates here are high, but a more demanding title would show the card's full spread relative to weaker GPUs.

How This Combo Ranks

Within the Roblox results table, the Core Ultra 7 155H plus RTX 5070 combination ranks 2040 out of 3711 tested combos. That places it just past the midpoint — better than roughly 45 percent of pairings in the database, behind the rest.

That ranking deserves interpretation. In raw performance terms this combo delivers triple-digit frame rates at 4K on every preset except Ultra (88 FPS), which is objectively strong output. The mid-table rank reflects the composition of the leaderboard for this specific title: Roblox is a game where CPU-limited configurations and older, lighter GPUs can still post very high frame rates at reduced settings, and where flagship desktop processors paired with top-tier cards dominate the top of the chart. A 28 W mobile CPU, however capable, gives up ground in that company even when the attached GPU — itself in the 82nd percentile — is doing excellent work.

The ranking is consistent with the component percentiles. The 155H sits in the 83rd percentile of all CPUs and the 5070 in the 82nd percentile of all GPUs, and the combo's mid-pack game rank is a plausible outcome of pairing a strong mobile chip with a strong desktop-class card in a title that does not stress either to its limits.

Settings Recommendations

The measured rows make the preset choice straightforward, because the frame-rate cost of higher settings is modest relative to the headroom available.

At 4K, High is the sweet spot: 109 FPS average is comfortably smooth for a sandbox game, and it avoids the step down to Ultra's 88 FPS. Players who prioritize absolute fluidity on a high-refresh 4K panel can drop to Medium for 123 FPS — the recorded 105 minimum on that preset means even the worst moments stay above common refresh thresholds. Ultra at 4K remains viable at 88 FPS if visual fidelity is the priority, but the data shows it is the least efficient preset per frame gained.

At 1440p, High delivers 193 FPS average — more than enough for the vast majority of displays — while Medium pushes 218 FPS with a recorded range of 185 to 250. Competitive-minded players running high-refresh monitors should use Low at 239 FPS or Medium; the Medium row's 185 FPS minimum suggests it holds up under load.

At 1080p, the choice is nearly academic. Low runs at 359 FPS, Medium at 326 (277 to 375), High at 289, and Ultra at 234. Any preset is viable; the only reason to go below High is chasing maximum refresh rates on extreme displays.

The general recommendation across the board: High at native resolution. In every tested case it clears triple digits, and the data shows no resolution where dropping to Medium or Low is necessary for a smooth experience. Players targeting high-refresh gameplay at 1080p or 1440p can use Medium as a balanced compromise, as its measured minimums (277 and 185 FPS respectively) remain exceptionally strong.

FAQ

Q: Can this setup run Roblox at 4K?

A: Yes, and comfortably. Measured averages at 3840x2160 are 135 FPS on Low, 123 on Medium, 109 on High, and 88 on Ultra. The Medium run recorded a minimum of 105 and a maximum of 142, so even frame dips stay in triple digits at that preset.

Q: Is the CPU or the GPU the bottleneck in this pairing?

A: The GPU. Frame rates fall sharply as resolution rises — Medium drops from 326 FPS at 1080p to 123 at 4K — which indicates the RTX 5070 is the limiting component. The wide Low-to-Ultra spread at 1080p (359 to 234) further shows settings are GPU-dependent rather than capped by the Core Ultra 7 155H.

Q: How does the Core Ultra 7 155H compare to rival CPUs?

A: It is effectively tied with its nearest competitors. The Intel Core i5-14600T matches it at a 0 percent delta, the AMD Ryzen AI 7 PRO 360 trails by 0.1 percent, the AMD Ryzen 5 7400F leads by 0.2 percent, and the AMD Ryzen 7 PRO 6850H leads by 0.4 percent. It sits in the 83rd percentile of all CPUs.

Q: Where does this combo rank among tested Roblox configurations?

A: Rank 2040 of 3711 tested combos — just past the midpoint. That reflects a strong mobile CPU paired with an 82nd-percentile GPU in a title where the leaderboards favor configurations that push this game's lighter workload to extreme frame rates.

Q: Which settings preset should be used for high-refresh gaming?

A: Medium. At 1080p it averages 326 FPS with a 277 minimum; at 1440p it averages 218 FPS with a 185 minimum. Low adds more headroom (359 and 239 FPS respectively) for extreme refresh displays.

Q: Is 12 GB of VRAM enough for this game?

A: Yes. The RTX 5070's 12 GB of GDDR7 with 672.0 GB/s of bandwidth produces triple-digit averages at 4K on three of four presets, so memory capacity and bandwidth are not constraints at any tested resolution in Roblox.
