Nvidia RTX Spark (N1X) Leaked Benchmarks vs Apple M4 Max: Cinebench 2026, Geekbench 6, Full Specs & Fall 2026 Launch

Nvidia officially unveiled the RTX Spark superchip at Computex on May 31, 2026, and the first wave of laptops and compact desktops is expected in fall 2026 . But ahead of those retail systems, a series of leaked benchmarks—some dating back to mid-2025—have given us an early picture of how this Arm-based processor stacks up against Apple Silicon and other rivals. Here is what the leaks show, along with the key specifications, confirmed devices, and pricing estimates.

Leaked Cinebench 2026 Benchmarks (July 18, 2026)

A leaked screenshot of a Microsoft Surface Laptop Ultra running an RTX Spark engineering sample in Cinebench 2026 was published on July 18, 2026 . The results :

Test	RTX Spark (ES)	Apple M4 Max (for comparison)
Single-Core	540 points	~676 points (estimated from user reports)
Multi-Core	5,771 points	Significantly higher; reports indicate the M4 Max is about 35.6% faster in multi-core

Sources report that in single-core the RTX Spark roughly matches the Apple M3 Max, while the M4 Max leads by a wide margin . In multi-core the RTX Spark also falls well behind the M4 Max . The leak also revealed configurable power limits of 80 W PL1 and 95 W PL2, closely matching Nvidia's previously disclosed RTX Spark power envelope of 45–80 W . All figures are from an engineering sample (pre-production) — final retail performance may improve with driver and firmware optimizations.

Geekbench 6 Leaks (June 2025)

An earlier Geekbench 6 result for the N1X (previously codenamed N1x) engineering sample, posted in June 2025 and subsequently removed but archived by multiple outlets, showed :

Test	Nvidia N1X (ES)	Apple M3 Max	Apple M5	Apple M5 Pro
Single-Core	~3,096	~3,124	~4,224	~4,242
Multi-Core	~18,837	~18,920	~17,465	~25,800

The N1X roughly tied the M3 Max from late 2023 but was ~36% behind Apple's M5 in single-core and well behind the M5 Pro in multi-core . The test system was an HP development board (model HP 83A3) running Ubuntu 24.04.1 .

Key Specifications (RTX Spark N1X — flagship SKU)

Component	Spec
CPU	20-core Arm v9.2 — 10× Cortex-X925 performance cores (up to 4.1 GHz) + 10× Cortex-A725 efficiency cores
GPU	Blackwell 2.0 with 48 SMs = 6,144 CUDA cores + 5th-gen Tensor Cores — roughly equivalent to a desktop RTX 5070
AI Performance	1 PFLOPS (FP4 precision) using NVFP4; capable of running 120-billion-parameter LLMs locally
Unified Memory	Up to 128 GB LPDDR5X-9400 at ~300 GB/s bandwidth, shared CPU+GPU
FP32 (GPU)	~31 TFLOPS
Process Node	TSMC 3nm
Platform	Full CUDA stack on Windows on Arm; NVLink-C2C die-to-die interconnect
Co-Design	Co-developed with MediaTek
TDP	45–80 W (full package)

Lower-tier SKUs

• N1X (18-core variant): 9× P-cores + 9× E-cores, ~40 GPU SMs (5,120 CUDA cores)
• N1 (standard): 12-core (8+4) or 10-core (7+3) CPU configurations with fewer GPU cores

Fall 2026 Launch Lineup & Confirmed Devices

Nvidia officially announced RTX Spark on May 31, 2026 at Computex . Shipments begin fall 2026.

Confirmed Manufacturer Lineup

Manufacturer	Confirmed Models	Notes
Microsoft	Surface Laptop Ultra (15-inch, mini LED PixelSense Ultra, 2,000-nit peak brightness)	First device seen in Cinebench leak; flagship AI PC
HP	HP OmniBook Ultra 16 and HP OmniBook X 14	HP claims these will be the world's thinnest RTX Spark devices
Dell	Dell XPS 16 Creator Edition (and others)	Confirmed multiple designs in development
ASUS	ASUS ProArt P16 and ASUS ProArt P14 (creator-focused, OLED displays)	Part of initial 8 confirmed laptop designs
Lenovo	Lenovo Yoga Pro 9n (and others)	Confirmed at Computex
MSI	MSI Prestige N16 Flip AI+	MSI representatives confirmed early partnership

Launch Scale

• 8 confirmed laptops arriving this autumn from the six manufacturers above
• 30+ total laptop designs expected at launch
• ~10 compact desktop models also planned
• Acer and GIGABYTE expected to follow later

Pricing Estimates

Nvidia has not announced official pricing. Estimates from analysts and press :

Tier	Estimated Price Range
N1-based devices (lower-end)	$1,799 – $2,500
N1X flagship devices (20-core)	$2,500 – $2,900

A Morgan Stanley analyst note (based on Computex channel checks) points to N1X machines around $2,899 and N1 models near $1,799 . These are premium AI PC price points — notably higher than typical Arm laptops today and squarely in MacBook Pro territory .

Key Caveats

• All benchmarks are from engineering samples and may not reflect final retail silicon.
• Nvidia has not published any official benchmark results.
• The Cinebench 2026 leak is from July 18, 2026; independent verification is still emerging.
• CPU single/multi-core performance appears to trail Apple's M4 generation significantly, but RTX Spark's main differentiator is its integrated Blackwell GPU + AI compute (1 PFLOPS), not raw CPU speed. Nvidia is pitching the chip as a "personal AI supercomputer" capable of local agentic AI workloads .
