The reported Cinebench R23 result for Intel’s Core Ultra 9 275HX was approximately 2,199 points in single-core and 39,375 points in multi-core. Published in February 2025, those figures came from a pre-release leak—not an Intel-certified test—but later results from shipping and near-shipping laptops broadly support the multi-core direction, with scores around 39,700 to 40,950 points.
The important qualification is that the 275HX does not produce one universal Cinebench score. Sustained power limits, cooling, firmware, memory, performance mode, and the laptop’s shared CPU-GPU thermal budget can materially change the result.

That percentage should not be treated as a fixed processor-to-processor uplift. The leak did not fully document the laptop model, BIOS, cooling system, memory configuration, power mode, ambient temperature, or test procedure. A Turbo-mode 275HX laptop and a Balanced-mode 14900HX laptop would not constitute a controlled comparison.
Why nearly 40,000 points is significant
A Cinebench R23 multi-core result near 40,000 places the 275HX in the highest tier of laptop CPU rendering performance. It suggests strong potential for workloads such as:
- CPU-based 3D rendering
- Software compilation
- Compression and decompression
- CPU-heavy video encoding
- Scientific, engineering, and simulation workloads that scale across threads
- Virtual machines and development environments with sufficient memory
- Heavy multitasking
Cinebench measures a rendering workload, however. A score of 39,375 does not mean every application will run 11% faster than on a Core i9-14900HX. Real-world results depend on software optimization, instruction mix, memory behavior, scheduling, GPU acceleration, and whether the laptop can sustain its initial power level.
Confirmed specifications: this is a 24-core, 24-thread processor
The 275HX is no longer merely an upcoming processor. Intel lists it as a launched Core Ultra processor Series 2 mobile part from Q1 2025. Its official specifications include:
- Architecture: Arrow Lake
- Total cores: 24
- Performance cores: 8
- Efficiency cores: 16
- Total threads: 24
- Maximum turbo frequency: 5.4 GHz
- Efficiency-core maximum turbo: 4.6 GHz
- Smart Cache: 36 MB
- L2 cache: 40 MB
- Processor base power: 55 W
- Maximum turbo power: 160 W
- Memory support: Up to DDR5-6400, subject to laptop implementation
- NPU: Intel AI Boost at 13 TOPS
- Integrated graphics: Intel Graphics with four Xe cores, up to 1.9 GHz
Intel’s specification page confirms that the chip has 24 threads, not 48. It does not use Hyper-Threading. The thread count comes directly from its eight performance cores and 16 efficiency cores.
That design makes the leaked result particularly notable, but core and thread counts alone do not explain performance. Performance cores and efficiency cores have different characteristics, and sustained power delivery and cooling remain critical in a laptop.

How it compares with the Core i9-14900HX
The leak suggested a clear multi-core advantage over the representative Core i9-14900HX result it cited, but a much smaller single-core difference. The safest interpretation is platform-to-platform evidence rather than a guaranteed generational ranking.
For a fair comparison, both laptops should use the same Cinebench version and comparable:
- AC power status
- Windows and laptop performance mode
- CPU and system power limits
- Cooling capacity and fan profile
- Memory capacity, speed, timings, and channel configuration
- BIOS and microcode maturity
- Benchmark duration and number of runs
The 275HX may be faster in a heavily cooled, high-power system while another 14900HX laptop may perform differently under a more aggressive power configuration. The leak therefore supports the possibility of a meaningful multi-core advantage, not the claim that every 275HX laptop defeats every 14900HX laptop.
Retail results provide stronger context
Later entries in Notebookcheck’s benchmark database broadly support the original multi-core direction:

| Schenker XMG Neo 16 E25 RTX 5090 | 200 W / 185 W listing | 40,951 |
Notebookcheck also lists single-core results in the low-to-mid 2,200s, including examples around 2,199 to 2,255. These results make the original leak look directionally credible, but they also show why a processor name is not a complete performance specification.

- NVIDIA GeForce RTX 5060 8GB GDDR7
- Wi-Fi 7 + Bluetooth 5.4
The power figures shown in benchmark databases may describe system-level or combined CPU/GPU operating limits rather than a simple processor-only wattage. They should not be casually equated with Intel’s 160 W maximum turbo power specification.
Leak versus current evidence
| Question | Leak-era answer | Current interpretation |
|---|---|---|
| Was the processor real? | It was treated as a pre-release product. | Intel lists it as launched in Q1 2025. |
| Reported multi-core result | 39,375 points. | Retail and near-retail examples reach roughly 39,700 to 40,950. |
| Reported single-core result | 2,199 points. | Later entries generally sit in the low-to-mid 2,200s. |
| Is the score universal? | The leak could not establish that. | No. Results depend heavily on laptop design. |
| Does it prove gaming leadership? | No. | Gaming requires CPU, GPU, frame-time, and cross-load testing. |
Why two 275HX laptops can score differently
The same Core Ultra 9 275HX can behave very differently across laptop models. Relevant variables include:
- Sustained CPU power and short-duration boost limits
- Silent, Balanced, Performance, or Turbo mode
- Chassis thickness and heatsink capacity
- Vapor chambers, heat pipes, and fan curves
- Ambient temperature and dust condition
- BIOS, microcode, and Windows power settings
- Memory speed, timings, capacity, and dual-channel operation
- AC versus battery operation
- Whether a discrete GPU is simultaneously consuming the thermal budget
- Whether the test is a single run or a repeated loop
Notebookcheck’s database includes 275HX systems with reported power configurations ranging from roughly 111 W to 205 W. Those figures are not directly interchangeable, but the spread is useful evidence that laptop implementation strongly influences the final Cinebench score.

Cinebench R23 is useful for comparing CPU rendering throughput and checking sustained multi-core performance between similarly configured laptops. It is not a direct measure of:
- Gaming frame rates or 1% lows
- GPU-limited performance
- Battery life or unplugged speed
- Fan noise and surface temperature
- GPU-accelerated video export
- NPU or AI performance
- Long-term throttling behavior
R23 scores also cannot be mixed directly with Cinebench 2024 scores. The original leak reportedly listed 135 single-core and 1,658 multi-core points in Cinebench 2024, but those numbers use a different benchmark and should not be compared numerically with the R23 results.

A high Cinebench score also does not guarantee better battery performance, quieter fans, or superior efficiency.
Buying advice: evaluate the laptop, not just the CPU
A 275HX laptop is a sensible choice when you want maximum plugged-in CPU performance and are considering a large gaming or workstation system with documented cooling and performance modes. It is especially attractive when independent testing confirms strong sustained results rather than only a short benchmark burst.
Be cautious when:
- The laptop is unusually thin for an HX-class design.
- The manufacturer does not disclose meaningful power modes or cooling details.
- The listing relies on a single benchmark screenshot.
- The test was performed on battery or with an unknown Cinebench version.
- The laptop pairs the processor with a powerful GPU that shares the thermal budget.
- You prioritize low noise, portability, or long unplugged battery life.
- The price premium is large over comparable Core i9 HX or Ryzen 9 HX systems.
Potential product families include Lenovo Legion, ASUS ROG Strix Scar, Razer Blade 18, MSI Raider/Vector/Crosshair, and Schenker/XMG Neo or Pro systems. Compare complete configurations using GPU model and wattage, memory upgradeability, display quality, SSD expansion, sustained performance, noise, temperatures, battery behavior, warranty, and current price—not the processor name alone.
Verdict
The Core Ultra 9 275HX Cinebench R23 leak was unofficial, but its central message was broadly credible. The reported 39,375-point multi-core score anticipated the flagship-level performance later seen in well-powered laptops, where results reached roughly 39,700 to 40,950 points.
The result should not be treated as a guaranteed score or proof of universal gaming leadership. The 275HX is a powerful 24-core, 24-thread mobile processor, but its real performance depends on sustained power, cooling, firmware, memory, and the laptop’s overall design. For buyers, the right question is not whether a laptop carries the 275HX label; it is whether that particular chassis can sustain the performance the chip is capable of delivering.
