ACEMAGIC K5 Review: Intel Core 5 320 vs Ryzen 5 PRO 7640HS, Which K5 Should You Buy?

Search Amazon for the ACEMAGIC K5 and you will find two different computers under the same name and almost the same small box. One runs Intel’s brand-new Core 5 320, the other AMD’s Ryzen 5 PRO 7640HS. They are not the same class of machine, and the right one depends on what you do. Here is what the specifications and published tests say about each.

Two different mini PCs called ACEMAGIC K5

ACEMAGIC sells the K5 with an Intel Core 5 320 (also called “Kron Mini K5”) and with an AMD Ryzen 5 PRO 7640HS. Both come with 16GB of LPDDR5 and a 512GB SSD in the US, but the processors, graphics and power budgets are very different.

The Intel K5 appeared in June 2026, one of the first mini PCs with Intel’s Wildcat Lake chips, the successors to the N-series found in most budget boxes. A cheaper Core 3 304 version with 12GB of memory also exists. The AMD K5 arrived on Amazon in October 2026 with a 2023 laptop chip that is a full class above: 6 Zen 4 cores with 12 threads and Radeon 760M graphics. ACEMAGIC also sells a 24GB version of the AMD model in Japan.

Sources: ACEMAGIC listings, Notebookcheck, TechRadar and Retro Handhelds (Intel K5); AMD and Notebookcheck (7640HS); Starry Hope’s model page and ACEMAGIC’s listings (AMD K5). The two K5s share the same chassis layout: six USB-A ports, HDMI, DisplayPort, USB-C, 2.5GbE and Wi-Fi 6. The differences are the chip, the memory speed and the USB-C port.

Processor performance: AMD wins in multi-core

In Cinebench 2024 multi-core, the Ryzen 5 7640HS averages 698 points against 402 for the Intel K5: about 74% more. Single-core speed is close, with a small lead for Intel (110 vs 103).

The Intel figures were measured on the K5 itself; the AMD figures are Notebookcheck’s averages across laptops with the Ryzen 5 7640HS. The PRO version uses the same cores and clocks. Mini PCs often run these chips at different power limits, so treat the gap as an order of magnitude.

The difference comes from threads. The Core 5 320 has six cores but no Hyper-Threading, and four of its cores are compact efficient cores. The 7640HS has six full Zen 4 cores with two threads each. In daily use, both feel quick in a browser, office apps and video calls; TechRadar even found the Intel chip faster in single-core work than the Core Ultra 5 125H. The AMD K5 pulls ahead when you run many apps at once, export photos or videos, compile code or run virtual machines.

Compared with the Intel N150 found in most budget mini PCs, both are a big step up: TechRadar measured the Intel K5 at about three times the Cinebench 2024 multi-core score of a Beelink ME mini with an N150 (402 vs 135). Our N150 vs N100 vs N97 comparison explains where those budget chips stop.

Graphics and gaming: only the AMD K5 can play

The AMD K5’s Radeon 760M has 8 compute units and runs many games at 1080p low settings. The Intel K5’s 2 Xe cores are fine for 4K video and office work, not for modern games.

Notebookcheck’s database gives the Radeon 760M an average of 2,260 points in 3DMark Time Spy (graphics score), and lists results such as 53 fps in F1 25, 43.6 fps in Ghost of Tsushima, 37 fps in Call of Duty: Black Ops 6 and 31 fps in Cyberpunk 2077 at 1080p low on laptops with this GPU. Older and lighter titles, esports games and emulation of most retro consoles run comfortably. Soldered dual-channel LPDDR5 helps here, because integrated graphics depend on memory bandwidth.

On the Intel K5, TechRadar measured 1,693 points in Time Spy, a different score type (overall rather than graphics) that still places it well below the Radeon 760M. Wildcat Lake’s media engine handles 4K and even 8K YouTube smoothly, as CNX Software saw on the Core 3 304 version, and drives three 4K screens for office work. If gaming matters at all, our gaming mini PC guide lists stronger options with Radeon 780M or 890M graphics.

Power, heat and noise

The Intel K5 is the frugal one: its Core 3 sibling idles at about 4W at the wall and draws about 30 to 33W under full load. The AMD chip is a 35 to 54W part, so expect more heat and fan noise under load.

CNX Software measured the Core 3 304 version of the K5, which uses the same chassis and cooler: 3.7 to 4.3W at idle, 12.5 to 15.9W playing 8K YouTube, and 29.7 to 33.0W sustained in Cinebench R23 after a short peak around 36W. Under that all-core load the processor reached about 92°C in a 28 to 30°C room and throttled, and the fan rose to 45.7 to 47 dBA measured 5 cm above the case, from about 38 dBA at idle. The Core 5 320 runs in the same 25W-class envelope, and Retro Handhelds described its unit as “whisper quiet” in normal use.

Nobody has published power or noise measurements for the AMD K5 yet. The 7640HS is designed for 35 to 54W, against about 25W for the Intel K5, so in heavy work it will draw more power and need more airflow from a similar small box. For office use, both chips spend most of their time near idle, where the difference matters less. Running 24/7 as a small home server, the Intel K5’s low idle draw is an advantage.

Memory and storage: soldered RAM, expandable SSD

Both K5s have 16GB of soldered LPDDR5: enough for Windows 11 and office work, but it can never be upgraded. On the Intel K5, the bundled SSD is a PCIe 3.0 drive in a slower x2 slot, at about 1,780 MB/s.

Soldered LPDDR5 is fast and runs in dual channel, which helps both the processor and the graphics. The trade-off is permanent: 16GB is comfortable today for Windows, browsers and office apps, tight for heavy multitasking with large photo or video projects, and too little for local AI models beyond small ones. If you need more, look for the 24GB AMD version or a mini PC with SO-DIMM slots, such as the GMKtec M5 Plus.

On storage, the Intel K5’s two M.2 slots are PCIe 4.0 x2, and ACEMAGIC fits a PCIe 3.0 SSD. TechRadar, ITPro and CNX Software all measured about 1,780 MB/s read and 1,690 to 1,750 MB/s write: fast enough to boot in seconds, but about half of what a good PCIe 4.0 drive can do, which is why TechRadar called the lane budget “diabolical”. The second slot adds up to 4TB, and tool-free access makes it easy. The AMD K5 also ships with a PCIe 3.0 drive and has a second M.2 2280 slot, for up to 8TB in total; no independent speed measurement has been published yet.

Ports and connectivity

The Intel K5 has six USB-A ports, a 20Gbps USB-C port that also accepts 100W power input, HDMI 2.0, DisplayPort 1.4, 2.5GbE and Wi-Fi 6. Neither K5 has USB4, Thunderbolt or OCuLink, so no external graphics card.

CNX Software measured 2.37 Gbps both ways on the Intel K5’s 2.5GbE port and about 830 to 840 Mbps over Wi-Fi 6, which is what you want from those standards. The USB-C port powering the PC is useful with a USB-C monitor that delivers power: one cable can carry video and power. The faster 10Gbps USB-A ports are all on the front. ITPro regretted the lack of an SD card reader and having only one USB-C port.

The AMD K5 uses the same port layout, according to Starry Hope: two 10Gbps USB-A ports on the front, four 5Gbps on the back, HDMI 2.0, DisplayPort 1.4, 2.5GbE, Wi-Fi 6 and Bluetooth 5.2. Its USB-C port is slower (10Gbps) and carries video, but it cannot power the PC, which uses a barrel connector. Neither version has USB4 or OCuLink, so no external graphics card later; if you want that option, see our OCuLink guide.

AI features: neither is a Copilot+ PC

Copilot+ requires a 40 TOPS NPU. The Intel K5’s NPU is rated at about 16 TOPS and the AMD chip’s at 10 TOPS, so neither gets Recall or the other Copilot+ features. Both can run small local AI models.

Retro Handhelds tested local AI on the Intel K5: with Intel’s updated NPU driver, a TinyLlama 1.1B chatbot generated about 17 tokens per second on the NPU, and the NPU was over five times faster than the processor on INT8 work in Geekbench AI. Software support was immature at launch, though, and needed new drivers. On the AMD K5, small models run on the Radeon 760M through apps like LM Studio, but 16GB of shared memory limits model size on both. For running real assistants at home, see our local AI mini PC guide and the NPU explainer.

Which K5 should you buy?

The AMD K5 for most people: more performance and real graphics in the same small box. The Intel K5 if you value low power, a quieter office PC, USB-C power input or the newest platform.

• Buy the AMD K5 (Ryzen 5 PRO 7640HS) for a family or home office PC that also plays games at 1080p low, heavy multitasking, photo editing, coding, or virtual machines. Its 12 threads and Radeon 760M make it the more capable machine.
• Buy the Intel K5 (Core 5 320) for office work, video calls, a three-screen desk, 4K streaming and a PC that stays quiet and sips power, including as an always-on light server with 2.5GbE. It is also the better choice if you want a strong NPU for future Windows AI features.
• Skip both if you need more than 16GB, upgradable memory, USB4 or OCuLink: look at the alternatives below.

Prices on Amazon move often, and ACEMAGIC runs frequent coupons. Compare both K5s on the day you buy: when the AMD version costs about the same or less, it is the better deal. Our guide to spotting fake discounts explains how to check that a coupon is real.

Verdict

The AMD K5 is the better buy for most people at a similar price; the Intel K5 is a well-connected, efficient office PC that makes sense if you will never game and want low power.

ACEMAGIC’s naming does buyers no favors: two very different computers share the K5 badge. Read the processor name in the listing before anything else. With the Ryzen 5 PRO 7640HS, the K5 is a capable small desktop for the whole family, including light gaming. With the Core 5 320, it is a modern, quiet office box held back by its graphics and its storage choice. In both cases, 16GB of soldered memory is the ceiling, so be sure it is enough for you.
