A 45 TOPS NPU lets AI run smoothly without an internet connection, while 32GB of RAM determines whether your machine starts to stutter and lag after three years of use. The two specs affect everyday experience in completely different ways. Many customers ask Hung Phat, "How many NPU TOPS is enough, and do I really need 32GB of RAM with a Gen5 SSD?" The answer depends entirely on what you do with the laptop. 2026 laptops are packing all three into one chassis, but they are not equally worth prioritizing.
45 TOPS NPUs and AI PCs: genuinely important or just marketing?
NPU stands for Neural Processing Unit. It sounds complicated, but the idea is simple: the CPU handles general work, the GPU handles graphics, and the NPU does just one thing, running AI tasks locally on the machine without sending data to the cloud. The NPU TOPS figure measures the processing power of this chip, with TOPS meaning trillions of operations per second. 40 TOPS or more is the threshold Microsoft set for the Copilot+ PC standard, meaning the machine counts as a "true AI PC."
| NPU generation | Representative chips | Real-world difference |
|---|---|---|
| Under 10 TOPS | Intel Core Ultra 100 (Meteor Lake) | AI camera features and light tasks; does not meet the Copilot+ standard |
| 40-55 TOPS | Snapdragon X Elite, Intel Lunar Lake, Ryzen AI 300 | Meets the AI PC standard, smooth local AI, better battery life than running the work on the CPU/GPU |
| AI GPU (high TOPS) | RTX 50-series, AMD RDNA 4 | Powerful for heavy AI work like rendering and 4K upscaling, but draws more power and runs hotter than an NPU |
An analogy helps: the NPU is like a dedicated AI hotline operator living inside your laptop. When you join a Zoom call and need background noise suppression, automatic captions, or the Recall feature to find something you viewed earlier, that operator handles it on the spot, with no need to call the switchboard (the cloud). The result is faster responses and less battery drain, since the CPU and GPU don't have to take on extra work. Before the Meteor Lake generation (Intel Core Ultra 100), laptop chips had almost no dedicated NPU, and NPU TOPS topped out below 10, enough for AI camera features but short of the 40 TOPS Copilot+ threshold.
The notable 2026 generation includes Snapdragon X Elite, Intel Lunar Lake and AMD Ryzen AI. All three architectures reach or exceed 40 TOPS, and the Ryzen AI 9 HX 370 in the ASUS Zenbook S 16 hits about 50 TOPS. Still, Hung Phat has to be blunt about one point: a high NPU TOPS figure does not raise FPS in games, does not render video faster, and does not replace an RTX GPU for heavy AI work. In other words, an impressive TOPS number does not turn an ultrabook into a workstation. If your workflow doesn't use Copilot, doesn't need automatic captions and doesn't involve Windows Recall, a 45 TOPS NPU is nearly invisible in everyday use.
The three real-world models Hung Phat most often recommends when customers ask about NPUs are the ASUS Zenbook S 16 (Ryzen AI 9 HX 370, around 40-55 million VND), the Surface Laptop 7 (Snapdragon X Elite, around 35-55 million VND) and the Lenovo Yoga Slim 7x from the Lenovo Yoga & IdeaPad line (Snapdragon X Elite, around 35-45 million VND). These machines meet the 2026 AI PC standard and also get noticeably better battery life than the previous generation, because the NPU takes light tasks off the CPU. If you work online a lot, spend plenty of time in meetings and need all-day battery, this is genuinely useful.
32GB of RAM vs. NPU TOPS: which one decides long-term performance?
RAM is temporary memory, where the operating system, browser, creative apps and virtual environments all live side by side. 16GB was a fine level for 2023-2024, but in 2026 the picture is different. Chrome with 20 tabs open eats about 4-5GB, Teams takes another 1-2GB, Photoshop with a large file open needs 4-6GB more, and with the operating system in the background and an integrated NPU sharing unified memory, 16GB starts to feel tight. The machine then uses the SSD as virtual memory (swap), and that is when you notice clear lag.
| RAM capacity | Who it suits | Real-world limits |
|---|---|---|
| 16GB | Office work, studying, light coding | Fills up easily with many Chrome tabs + AI apps + Photoshop at the same time |
| 32GB | Creative work, coding, heavy multitasking, 4-5 years of use | The level to choose for 2026; less SSD swapping, less lag over time |
| 64GB+ | Heavy video editing, AI datasets, large CAD, many virtual machines | A mobile workstation; high price, battery life is usually worse |
When advising customers choosing between a 16GB machine with a Gen5 SSD and a 32GB machine with a Gen4 SSD at the same price, Hung Phat usually asks one question: "Do you often keep a lot of things open at once?" If so, 32GB of DDR5 or LPDDR5X is the more practical answer. This is the point where spec sheets most easily mislead buyers. The theoretical read/write speed of a Gen5 SSD reaches about 15,75GB/s, twice as fast as Gen4. That is impressive on paper, but in ordinary office and creative workflows you will struggle to feel the difference. SSD swapping caused by too little RAM is what really produces stutter and lag, and it wears down the drive's lifespan over time.
One downside deserves a plain mention: many 2026 ultrabooks use RAM soldered to the motherboard, so it can't be upgraded after purchase. LPDDR5X is fast, but you get only one chance to choose correctly from the start. The Dell XPS 14 and XPS 16 in 32GB versions run around 45-80 million VND, the Lenovo ThinkPad T14s in 32GB about 30-50 million VND, and ASUS Zenbook and ROG models in 32GB about 30-70 million VND depending on configuration. If you keep a laptop for 4-5 years and often run Photoshop, Premiere, an IDE or virtual machines, 32GB deserves priority over a Gen5 SSD at the same budget.

Do you really need a Gen5 SSD, and who should prioritize what when buying a laptop in 2026 in Ho Chi Minh City?
A PCIe Gen5 NVMe SSD has a theoretical bandwidth of about 15,75GB/s, twice that of PCIe Gen4. It sounds very appealing, but what happens in practice? For everyday tasks like opening apps, browsing the web, quick photo edits or writing documents, a Gen4 SSD running at 6-7GB/s stopped being the bottleneck long ago. A Gen5 SSD is an upgrade that only clearly shines when you constantly copy large files, work with heavy datasets or export 4K RAW video. Compared with chasing a high NPU TOPS figure or a Gen5 SSD, this is why Hung Phat often says: if you have to choose between upgrading RAM and upgrading the SSD, put 32GB of RAM first.
Looking back at all three factors, an NPU TOPS figure of 45 or higher is what helps a machine "last longer" as the Windows AI ecosystem expands. It suits people who work online a lot, need durable battery life and want local AI features that don't depend on the internet. 32GB of RAM is what decides whether the machine stutters after 3 years, and it can't be skipped if the RAM is soldered and you multitask heavily. A Gen5 SSD is a bonus if the budget allows, not something to sacrifice RAM or the NPU for. Customers who visit Hung Phat in Ho Chi Minh City and ask this question usually get the same advice: balance the three according to your real needs, and don't let spec sheet numbers lead you.

Frequently Asked Questions (FAQ)
What RAM and NPU configurations are common in mid-range laptops in 2026?
Most mid-range laptops in 2026 (around 20-35 million VND) use 16GB of LPDDR5X RAM and a PCIe Gen4 SSD, with NPU TOPS typically at 10-20, short of the 40 TOPS Copilot+ standard. To get an NPU of 40+ TOPS you generally need to spend 30-45 million VND or more, with chips such as Ryzen AI 300 or Snapdragon X. 32GB of RAM shows up more often in the mid-range in 2026, but it is still usually a paid upgrade over the base version.
Can you upgrade the RAM and SSD on a 2026 laptop yourself?
It depends entirely on the model. Thin-and-light ultrabooks like the Zenbook S 16, Surface Laptop 7 and Yoga Slim 7x all use LPDDR5X RAM soldered to the motherboard, so it can't be upgraded after purchase. The SSD in many machines is still a replaceable M.2 2280 drive, but some, like the Surface Laptop 7, solder the SSD too. The newer ThinkPad T14 is friendlier, letting you open the case and upgrade the SSD. Hung Phat advises choosing the right RAM from the start, especially if it's soldered. Don't skimp on the extra 3-5 million VND to get 32GB, because there is no way to fix it later.
How much RAM is enough for the next 3-5 years?
For purely office and study workflows, 16GB is still fine until around 2027-2028. But if you use local AI, run creative apps like Photoshop or Premiere, code with a heavy IDE or run virtual machines, 32GB is the comfortable level for 4-5 years of use without worrying about SSD swap. With 40+ TOPS NPUs, the chip typically uses unified memory shared with the integrated GPU, which makes 32GB even more sensible. 64GB is only necessary if you edit 4K video constantly, run large AI datasets or need several virtual machines in parallel.
How much do laptops with a capable NPU, 32GB of RAM and a Gen5 SSD cost?
Machines that combine all three typically fall in the 40-80 million VND range. The ASUS Zenbook S 16 (Ryzen AI 9 HX 370, 32GB, Gen4/Gen5 SSD depending on the version) costs about 40-55 million VND. The Dell XPS 14 and XPS 16 in 32GB versions cost about 45-80 million VND. The Lenovo ThinkPad T14s in 32GB costs about 30-50 million VND, with an NPU around 40 TOPS. If your budget is under 35 million VND, you usually have to accept a trade-off on one of the three, and according to Hung Phat, dropping the Gen5 SSD is the most reasonable sacrifice of the three.
