The Lenovo ThinkPad X9-15p Gen 1 Aura Edition puts Intel’s H-series Core Ultra Series 3 processors and Arc B390 graphics in a 15.3-inch aluminum notebook that starts at 1.5kg (3.31lb). It belongs to the X9 branch of the ThinkPad line, which drops the TrackPoint for a large haptic touchpad, and Lenovo aims it at creators, analysts, and STEM professionals who want workstation-class processors without a discrete GPU. Our review unit runs the Core Ultra X7 358H with 32GB of LPDDR5X-9600 memory, a 1TB SSD, and the 2.8K OLED touch panel.
Key Takeaways
- A 16-core H-series processor in a 3.3-pound, 15-inch ThinkPad. The X9-15p pairs the Core Ultra X7 358H and 12-Xe-core Arc B390 graphics with a 2880×1800 OLED panel and an 88Wh battery in a chassis that measures 7.25mm at the front edge and 17.9mm at its thickest point.
- The chassis holds 99.6 percent of its opening score over 30 minutes. Cinebench 2026 multi core reached 4,594, which is 8 percent behind a mini PC with the same processor and 3 percent behind the Core Ultra X9 388H in a 16-inch workstation, and the steady-state loop score settled at 4,595.
- Shared memory lets integrated graphics load a 20B model. With 18.1GB of GPU-usable memory, the X9-15p completed our coding agent test on gpt-oss:20b in all three runs with 11 of 11 tests passing. A notebook with a 12GB GeForce RTX 5070 could not start that test.
- Token rates trail the NVIDIA systems by 2x or more in MLPerf Client. MLPerf Client measured 27.3 tokens per second on Llama 3.1 8B, level with the other Arc B390 systems, against 66.2 on the RTX 5070 and 55.7 on the RTX Spark N1X.
- Long floating-point jobs open a wider gap to the desktop. GROMACS finished 21 percent behind the mini PC with the same chip and all-thread Stockfish 16 percent behind, where 7-Zip, Blender Monster, and x265 stayed within 3 to 5 percent.
- Memory is soldered and our SSD is a Gen4 drive in a Gen5 slot. The 1TB UMIS drive read at 7,067MB/s and wrote at 6,362MB/s, about half the read rate of the Gen5 drives in the NUC 16 Pro and the T1g. Buyers who want the 27B and 35B local model tiers need to order the 64GB option up front.
Where the X9-15p Sits
Lenovo describes the X9 family as a modern take on the ThinkPad, and the 15p is the model built on Intel’s H-series processors. Lenovo says an improved thermal design enables up to 30W TDP performance in this chassis. Processor choices are the 12-core Core Ultra 5 338H with Arc B370 graphics and the 16-core Core Ultra X7 358H and X7 368H, which both carry the Arc B390.
There is no discrete GPU option anywhere in the range, which sets the X9-15p apart from the ThinkPad P1 and T1g and puts its graphics and local AI performance entirely on the Arc B390 and shared system memory. Lenovo’s pitch for the model leans on on-device AI and multi-day battery life, and it quotes up to 23.2 hours in MobileMark 30 for a touch configuration with our processor and 64GB of memory.
Buyers who manage fleets should note that Intel vPro is tied to the processor choice. Lenovo lists the Core Ultra 5 338H and Core Ultra X7 368H as vPro platforms, and the X7 358H in our unit ships without it. The security hardware is otherwise standard ThinkPad, with a discrete TPM 2.0 certified to FIPS 140-3, a match-on-chip fingerprint reader in the power button, and a self-healing BIOS.
Lenovo.com lists our configuration, model 21VV002AUS, at $2,629 and in stock at the time of writing, with the Core Ultra X7 358H, 32GB of memory, a 1TB SSD, and the OLED touch panel. The range starts at $1,985.76 for a build-to-order model with the Core Ultra 5 338H, 32GB, and 1TB. Memory tops out at 64GB and storage at a single 2TB drive, so the upgrade decisions that matter are made at purchase.
Bouw en Ontwerp
The X9-15p uses aluminum for the top and bottom covers, 50 percent of it recycled, in a finish Lenovo calls Thunder Grey. It measures 339.5 x 228.5mm and is 7.25mm thick at the front edge and 7.65mm at the rear, with a 17.9mm maximum where a raised bar crosses the bottom cover. Lenovo calls that bar the Engine Hub and uses it to house components, ports, and ventilation, which leaves the rest of the chassis under 8mm thick.
In hand, the X9-15p sits toward the prosumer end of the ThinkPad range. The metallic finish replaces the rubberized black coating of traditional ThinkPads, and the chassis edge stays very thin from the front until it reaches the ports, where it steps out to the depth that HDMI and USB-C connectors need on both sides. That step keeps the notebook looking slim, and it will divide opinion: we would take a consistent edge over the bump-out.
Lenovo tests the chassis against 12 MIL-STD-810H methods and more than 26 procedures. The recycled content extends past the covers to the keyboard frame, 85 percent post-consumer plastic in the keycaps, 90 percent in the speaker and battery enclosures, and 100 percent recycled cobalt in the battery cells. Starting weight is 1.5kg (3.31lb) with the 88Wh battery installed, and the 100W adapter and its enclosure use 90 percent post-consumer plastic as well.
The left side carries HDMI 2.1 at up to 4K and 60Hz, two Thunderbolt 4 ports, and a 3.5mm combo jack, and the right side has an SD card reader, a third Thunderbolt 4 port, and one USB-A at 10Gbps with always-on charging. Each Thunderbolt port supports DisplayPort 2.1 and USB Power Delivery from 15 to 100W. The system drives up to four displays, including the internal panel. Wireless is Intel Wi-Fi 7 BE211 with Bluetooth 5.4, and there is no Ethernet port, WWAN option, or pen support.
The keyboard is a six-row, spill-resistant layout with 1.35mm of key travel, an LED backlight, and a Copilot key, and it has no TrackPoint or dedicated buttons. Pointing is handled by a buttonless glass haptic touchpad that measures 85 x 135mm. In use, the keyboard is comfortable, and the touchpad is generously sized. Longtime ThinkPad users will need to decide whether they can live without the red pointing stick, because no X9 configuration offers one.
Above the display sits a 10MP camera with an IR sensor for Windows Hello and an electronic shutter on the F9 key. A time-of-flight sensor adds presence features: the notebook can wake as the user approaches, lock when the user leaves, and dim the panel when the user looks away. Audio comes from six speakers: four 2W woofers and two 2W tweeters with Dolby Atmos tuning, plus a dual-microphone array.
Every X9-15p ships with the same panel: a 15.3-inch, 16:10 OLED at 2880×1800, offered with or without touch, and our unit has the touch version. Lenovo rates it at 500 nits in SDR and 1,100 nits at HDR peak, with 100 percent DCI-P3 coverage, a 30 to 120Hz variable refresh rate, DisplayHDR True Black 1000, Dolby Vision, and X-Rite factory color calibration. We have not measured panel output or battery life yet.
Memory is LPDDR5X soldered to the board at 32GB or 64GB, and storage is a single M.2 2280 slot wired for PCIe Gen5 x4 with drives up to 2TB. The bottom cover is held by six captive Phillips screws, and Lenovo lists the SSD, speakers, and base cover as parts an owner can replace, with the battery as an optional-service part. The 88Wh battery charges over USB-C from a 100W GaN adapter, with Rapid Charge to 80 percent in one hour while the system is off or asleep.
With the cover off, two fans sit at either side of the system board and share a heat pipe that crosses the processor and feeds fin stacks along the rear edge, under the Engine Hub. The 88Wh battery fills the front half of the chassis, the SSD sits under a shield between the fans, and speaker modules occupy the front corners.
The Aura Edition name refers to a set of Lenovo software features. Smart Modes switches system settings across six profiles for working, gaming, creating, entertainment, meetings, and learning, from a widget or inside Lenovo Vantage, and the function row has a dedicated mode key at F8. Smart Share covers Tap to Launch for moving photos between a phone and the notebook and Tap to Pair for Bluetooth accessories, and Smart Care connects users to Lenovo support technicians by chat or phone. None of these features change the benchmark configuration described below.

Testopstelling en methodologie
Our review unit runs the Core Ultra X7 358H with Arc B390 graphics, 32GB of LPDDR5X-9600, and a 1TB Gen4 SSD on Windows 11 Pro, with benchmarks tested on the Best Performance power mode. We ran the suite while plugged in, on BIOS 1.17 and Intel graphics driver 32.0.101.8509. Battery life will follow in a later update.
Results come from full, Peak-profile runs of sr-client, our scripted client benchmark suite. The X9-15p, the NUC 16 Pro, and the ThinkPad T1g ran version 1.13, and the two Dell systems ran version 1.11; the benchmark applications match across those releases, including Cinebench 2026, 7-Zip 24.09, Blender 4.5, Stockfish 19, GROMACS 2025.3, and MLPerf Client v2.0.
The suite applies the same settings everywhere: Windows power mode at Best performance, display at 50 percent brightness, all sleep and display timers off, Windows Firewall and UAC prompts off, and VBS and Memory Integrity left as shipped. Each result is the median of repeated passes, and the suite reruns a test if its spread exceeds 2 percent before accepting it.
The comparison set starts with the ASUS NUC 16 Pro, a mini PC with the same Core Ultra X7 358H, 64GB of memory, and no battery or thin chassis to manage, so it shows what the processor does with desktop cooling. ASUS rates the 358H at a 65W configurable TDP in that chassis, a little more than twice the 30W Lenovo cites for the X9-15p. The Dell Pro Precision 5 16S carries the Core Ultra X9 388H with Arc Pro B390 graphics in a 16-inch mobile workstation, which makes it the closest notebook to the X9-15p on silicon.
De Lenovo ThinkPad T1g Gen 9 adds a 12GB GeForce RTX 5070 Laptop GPU to a Core Ultra 7 366H and shows what a discrete card changes within Lenovo’s lineup. The Dell XPS 16 Creator Edition runs NVIDIA’s 20-core RTX Spark N1X with 64GB of unified memory and represents the Arm alternative at a similar screen size.

Lokale AI-prestaties
The Arc B390 has no dedicated memory and draws from system RAM, and on our 32GB unit the suite measured 18.1GB of GPU-usable memory. That clears the 16GB floor for our tiered local AI tests, so model loading and the coding agent both ran on the X9-15p, where the T1g’s 12GB RTX 5070 measured 11.7GB and could not start them. The cost is speed, because the Arc B390 generates tokens at roughly half the rate of the NVIDIA hardware in this group or less.
MLPerf Client v2.0

| Phi-4-mini, token rate (tokens/s) | 41.7 | 41.1 | 41.5 | 114.1 | 96.2 |
MLPerf Client runs through OpenVINO on the three Arc systems and through llama.cpp with CUDA on the two NVIDIA systems, so the columns compare engines as well as hardware. The X9-15p generated 27.3 tokens per second on Llama 3.1 8B and 41.7 on Phi-4-mini, within 2 percent of the NUC 16 Pro and the Precision. The RTX 5070 in the T1g is 2.4 times faster on Llama at 66.2 tokens per second, and the N1X is 2.0 times faster at 55.7. The Arc systems post the quickest first token on Llama at 0.20 to 0.21 seconds.

The model-load test times Ollama from launch to first token on gpt-oss:20b, a 12.8GB model, cold from the SSD and warm from the page cache. The X9-15p took 8.63 seconds cold and 8.01 seconds warm, and it is the only system here where the warm load saved less than a second. The 64GB Intel systems dropped to 4.2 to 4.4 seconds warm, which points to the 32GB configuration having little page cache to spare once the model is resident in shared memory.
The coding agent test runs Crush against gpt-oss:20b with a 64K context through a fixed programming task, three times, with up to three rounds each. The X9-15p succeeded on all three runs with 11 of 11 tests passing, at a median of 374 seconds and 18.3 tokens per second. Individual runs ranged from 229 to 410 seconds, and the NUC 16 Pro and the Precision each had runs that failed the task, so wall time here reflects the path the model took as much as the hardware.
Running Speedometer beside the agent, the browser score fell from 40.8 to 32.4, a 1.26x slowdown that was the smallest in the group, and the agent’s generation rate dropped from 18.3 to 15.2 tokens per second. The next tier up needs more memory than this unit has: the 35B agent model requires about 40GB and the 27B serving model 30GB of GPU-usable memory, and both ran on the 64GB NUC 16 Pro. With soldered memory, that makes the 64GB option the one to order for larger local models.

The Core Ultra X7 358H scored 4,594 in Cinebench 2026 multi-core and 511 in single-core in the X9-15p. The same processor in the NUC 16 Pro, running at more than twice the rated power, reached 4,980 and 512, so the thin chassis costs 8 percent in multi-core work and nothing in single-core work. The X9-15p finishes 3 percent behind the Precision’s Core Ultra X9 388H and 7 percent behind the T1g’s Core Ultra 7 366H on multi-core. The N1X in the XPS 16 leads the group at 6,631, a 44 percent margin.

The Precision, a 16-inch workstation, held 95.2 percent in the same test and ended at 4,413, so the X9-15p passes it once both chassis are warm. Lenovo’s power limits appear to be set at a level the cooling system held for the full 30-minute loop.

Across the content creation tests, the X9-15p tracks the NUC 16 Pro at a 3 to 8 percent deficit: 104.5 against 107.7 GIPS in 7-Zip, 125.5 against 132.0 samples per minute in Blender Monster, and 28.6 against 30.1 fps in x265, with Blender Classroom the widest gap at 60.4 against 65.6. The LLVM build took 359 seconds, 6 percent longer than the NUC and 3 percent longer than the Precision and the T1g. The X9-15p is the slowest of the four Intel systems in most rows, by margins that stay in single digits.
The N1X leads the multi-threaded rows by wide margins, including 41 percent in 7-Zip, 58 percent in Blender Monster, and a 232-second LLVM build that finishes about two minutes sooner. SVT-AV1 is the exception, where the X9-15p encoded at 80.1 fps against 14.0 fps on the Arm laptop, and x265 narrows the N1X lead to 36 percent at 38.8 fps.

Long floating-point workloads show the largest gap to the desktop. GROMACS benchMEM ran at 21.24 ns/day on the X9-15p against 26.84 on the NUC 16 Pro, a 21 percent deficit, and OpenBLAS DGEMM reached 469.2 GFLOPS against 527.4. The X9-15p averaged 3,249MHz through the 32-minute GROMACS run, its lowest mean clock in any CPU test apart from Stockfish. It still finishes 22 percent ahead of the XPS 16 in GROMACS and 32 percent ahead in DGEMM.
The X9-15p leads the Intel group on memory bandwidth, where its LPDDR5X-9600 delivered 91.3GB/s in STREAM Triad against 81.5 to 83.0GB/s for the three systems on LPDDR5X-8533, a 10 to 12 percent advantage. Memory latency at 4KiB pages was also the lowest of the five systems at 109.9ns. The N1X’s LPDDR5X-9400 remains well ahead on bandwidth at 122.9GB/s, the one memory result where the Arm system leads this group.

SuperTuxKart at 1080p with the highest preset is the suite’s one game test, and the X9-15p averaged 163.9 fps, within 3 percent of the other two Arc B390 systems. The T1g’s RTX 5070 is 26 percent faster at 206.8 fps, and the XPS 16 is 52 percent faster at 248.6. The game’s steady FPS figure, which tracks the low end of frame delivery, came in at 77 fps on the X9-15p. The panel tops out at 2880×1800, so the suite’s 4K pass did not run.
For GPU encoding, FFmpeg with HEVC Quick Sync ran at 128 fps on the suite’s Big Buck Bunny clip, identical across all three Arc systems. The Arc B390 gives the X9-15p enough graphics performance for light gaming and hardware-accelerated video work, and buyers who need more will find that no configuration of this notebook adds a discrete card.

The 358H reached 96C to 97C in every sustained CPU test and held there, with mean clocks between 3,249 and 3,705MHz under those loads and no decline across the 30-minute loop. GPU-led work ran much cooler on the processor side, at a 60C mean during MLPerf Client and 63C during LLM serving. The SSD peaked at 66C during the 82-minute storage run with a 55C mean, and stayed at or below 56C in the other tests. Fan noise during the benchmark runs was in line with the other notebooks we have tested recently.

The 1TB drive in our unit is a UMIS PCIe Gen4 SSD, installed in a slot that supports Gen5. It read at 7,067MB/s and wrote at 6,362MB/s on the 25GiB footprint, with the read figure near what a Gen4 x4 link allows, and both are 9 to 12 percent ahead of the Gen4 SK hynix drive in the XPS 16. The Gen5 drives in the NUC 16 Pro, and the T1g read at roughly twice that rate, at 14,236 and 13,525MB/s.
Peak 4K random read reached 700K IOPS, within 4 percent of the T1g’s Gen5 Micron drive, and random write is the softer side. The UMIS drive peaked at 393K write IOPS and managed 222K at QD32 across four jobs, the lowest of the four Intel systems, and the suite flagged both write figures for variance between passes. Lenovo lists Gen5 Performance SSDs at 1TB and 2TB as options for this model, and other drives may ship under the same 1TB Gen4 option, so these figures describe our unit.
Conclusie
The ThinkPad X9-15p Gen 1 Aura Edition delivers most of what the Core Ultra X7 358H can do in a chassis that weighs 1.5kg. It finished within 8 percent of a mini PC with the same processor in Cinebench and within 3 to 5 percent in 7-Zip, Blender Monster, and x265, and it held 99.6 percent of its opening score through a 30-minute loop. At $2,629 as tested, it costs about half the $5,349 T1g configuration, and its Arc B390 with 18.1GB of usable memory ran the 20B coding tier to completion in every attempt, which the T1g’s 12GB card can’t load.
The limits follow from the same design choices. Token rates on the Arc B390 are roughly half those of the RTX 5070 and the N1X or lower; image generation is impractical, and long floating-point jobs such as GROMACS ran 21 percent behind the desktop. Memory is soldered; our 32GB unit can’t handle the 27B and 35B model tiers, and the Gen4 SSD leaves the Gen5 slot’s speed unused. The 358H also ships without vPro.
That makes the X9-15p a good fit for analysts, developers, and creators who want a light 15-inch notebook with sustained 16-core performance, a color-calibrated OLED panel, and enough shared memory for mid-size local models, and who can work without a TrackPoint. Buyers who need a discrete GPU should look at the ThinkPad T1g or P1, and buyers who put multi-threaded throughput or AI token rates first will be better served by the N1X systems.
