Acemagic RX16 Panther Lake Laptop: Core Ultra X7 358H Specs, Price and Key Tradeoffs

What changed: from Zen 3+ to Panther Lake​

According to Notebookcheck, Acemagic has previously sold essentially the same platform with aged AMD Ryzen 9 6900HX, which paired eight Zen 3+ cores with Radeon 680M integrated graphics. That older model is still on Acemagic's European storefront, which describes the ACEMAGIC RX16 laptop equipped with the AMD Ryzen 9 6900HX processor, which can reach a turbo frequency of up to 4.9 GHz. It features 16 GB of LPDDR5 RAM and a 512 GB SSD.

The new chip's specs:

• CPU layout: Intel specifies 16 cores and 16 threads: four performance cores, eight efficiency cores, and four low-power efficiency cores.
• Clocks and cache: Maximum turbo frequency reaches 4.8GHz, and the processor includes 18MB of Intel Smart Cache.
• Process and power: Intel manufactures the CPU portion using its 18A process and lists processor base power at 25W and maximum turbo power at 80W.
• NPU: It can boost to 4.8 GHz and comes with a 50 TOPS NPU.
• Graphics: It comes with Intel's Arc B390 integrated GPU with 12 Xe3 cores clocked at up to 2.5 GHz. Intel's spec sheet rates the GPU at up to 122 TOPS of INT8 compute and lists hardware ray tracing, DirectX 12 Ultimate and AV1 hardware encode and decode.

Intel's specification page includes a detail buyers should know about. On H-series Core Ultra chips, the Arc graphics branding and performance tier only apply when the system has at least 16 GB of memory in a dual-channel configuration. Otherwise the same silicon appears as plain "Intel Graphics." Acemagic's US listing gives the RX16's memory as 12 GB × 2, so it meets that requirement and you get the full Arc B390, not a cut-down version.

Section summary: The platform itself is unchanged. What's new is a current-generation 18A processor with a far stronger integrated GPU and an NPU that the old Ryzen 9 6900HX didn't have.

Memory and storage​

Acemagic pairs the chip with 24 GB of LPDDR5-7467 and a 1 TB PCIe 4.0 SSD. The memory is soldered to the board and can't be upgraded. The Core Ultra X7 358H supports LPDDR5X at up to 9600 MT/s, so the RX16 doesn't run its memory at the chip's maximum rated speed. That matters most for the integrated GPU, which shares system memory.

Storage is easier to expand. Acemagic's US spec page lists:

1. Two M.2 2280 slots
2. One slot for PCIe 3.0/4.0 drives and one for PCIe 5.0 drives
3. Up to 2 TB per slot and 4 TB in total
4. No SATA SSD support

The PCIe 5.0 slot is unusual for a laptop at this price. Don't get too excited, though: a Gen5 drive in a thin chassis may run hot and throttle. That's general industry experience; nobody has tested this laptop yet.

Section summary: 24 GB is a reasonable amount today, but you're stuck with it. Storage is where you can upgrade later.

Display, ports and chassis​

Most of the old laptop carries over. Acemagic kept the 16‑inch 180‑degree hinge screen, Wi‑Fi 7, full‑range ports, backlit keyboard and physical camera privacy switch. The panel is 16:10, 1920 × 1200 and 60 Hz.

Port list according to Acemagic's US page:

The spec page lists dimensions of 357 × 247.6 × 19.9 mm but doesn't give a weight. Acemagic also advertises 100 W USB-C PD charging.

The 60 Hz panel is the obvious weak point. Arc B390 is the kind of iGPU that can make light gaming reasonable. Pairing it with a 60 Hz screen is like putting sports tyres on a car with a speed limiter. The Gadgeteer's assessment was similar: on paper, there is plenty to like, although the fixed memory, 60Hz display, and battery capacity present tradeoffs.

The cooling claims don't agree​

Here the numbers start to conflict. Notebookcheck reports that the RX16's dual fans and vapour-chamber heat spreader are what Acemagic says allow up to 65 W of sustained performance. Technetbook also quotes the 65 W figure but describes the hardware differently: cooling is handled by an internal thermal system featuring 2 fans and 2 copper heat pipes.

The Gadgeteer, working from Acemagic's own specs, noted that ACEMAGIC, however, specifies a 45W maximum for the RX16's implementation. Cooling, firmware, and power settings will therefore determine sustained performance. Acemagic's French product page gives the same 25 W default and 45 W maximum.

So there are three different figures: Intel's 80 W maximum turbo for the chip, Acemagic's 65 W marketing claim, and a 45 W maximum in the regional spec tables. None of the available pages explains the gap or says what "65W of performance" actually measures. Until someone tests it, treat the 65 W figure as marketing, not a measured sustained CPU load.

AI PC credentials and Copilot+​

Acemagic sells the RX16 as a "Copilot+ PC Ready" AI laptop. The 50 TOPS NPU is above the 40 TOPS threshold Microsoft set for Copilot+ PCs, and 24 GB of RAM and 1 TB of storage exceed the other published minimums. On paper, the hardware qualifies for NPU features in Windows 11 such as Windows Studio Effects, which Intel lists as supported.

Headline TOPS numbers need some care, though. Acemagic's F2A mini PC uses the same chip, and TechPowerUp reported that combined CPU, GPU, and NPU processing enables the system to reach up to 180 TOPS of total AI performance. Gizmochina called that figure up to 180 TOPS of theoretical AI performance. The key word is theoretical. Most Windows AI features only use the NPU, and third-party apps each choose their own accelerator.

Price, availability and warranty​

Notebookcheck reports that Acemagic has refreshed its RX16 laptop with an Intel Panther Lake CPU, and the US store currently lists one configuration (24 GB + 1 TB) at $1,159, next to a crossed-out $1,299 price. The US page quotes delivery in 3–5 business days, a 30-day return window and a two-year warranty. The UK store marks the 358H option as presale, and The Gadgeteer quoted a UK price of £1,039.00 (About $1,380). Prices and stock can change, so check before you buy.

For comparison, Acemagic's F2A mini PC with the same processor was, per Gizmochina, priced at $1,099 during the preorder period, down from the stated $1,699 regular price, and it came with 32 GB of LPDDR5X. The laptop costs slightly more than that preorder price but adds a screen, keyboard and battery, and has less memory.

Who should consider it?​

• Worth a look: Buyers who want a large-screen Windows 11 Pro laptop with a strong iGPU, a Copilot+-capable NPU and room for a lot of storage, and who don't care about a high-refresh display.
• Probably skip: Anyone who expects to need more than 24 GB of RAM within the next few years, or anyone buying mainly for gaming who wants more than 60 Hz.
• Wait for reviews: Anyone whose decision depends on sustained performance. Nobody has published RX16 benchmarks yet, and Acemagic's cooling and power figures don't agree with each other.

The processor refresh gives the RX16 a big jump in hardware, but it's still the same laptop around a new chip. Most of the value is in the silicon, and the screen, fixed memory and conflicting power numbers are real drawbacks. Until independent testing shows how the chip performs in this chassis, the specs are all buyers have to go on.
