Lenovo IdeaPad Slim 3X vs ASUS Vivobook Go 15: Which Laptop Should You Buy?

A newer laptop is not always the better buy, especially when the newer model comes with less memory. The 2025 Lenovo IdeaPad Slim 3X offers 16GB RAM, a Snapdragon X processor and a 15.3-inch WUXGA display. The 2026 ASUS Vivobook Go 15, meanwhile, costs less but comes with 8GB RAM, a Ryzen 3 30 processor and a 15.6-inch FHD display.

The price difference is currently around ₹14,650, with the Lenovo listed at ₹66,600 and the ASUS at ₹51,948. That is a considerable gap for someone shopping for a laptop for work, college or everyday use. However, the cheaper laptop also comes with a memory limitation that could matter if you regularly switch between multiple applications.

I would lean towards the Lenovo if I wanted more room for multitasking and planned to keep the laptop for several years. However, its Windows on Arm platform means application compatibility needs to be checked before buying. The ASUS is the more sensible choice for a tighter budget and lighter workloads. Here is how the two compare and when spending more on the older model makes sense.

Older Laptop or Newer Budget Model

The Lenovo IdeaPad Slim 3X and ASUS Vivobook Go 15 target buyers who need a laptop for everyday computing, but they approach the price point differently. The Lenovo offers more memory and a Snapdragon X platform, while the ASUS keeps the starting cost lower with an 8GB RAM configuration and a Ryzen processor.

The difference is not simply about which laptop has the better specifications on paper. It is about whether you will benefit from the Lenovo's additional memory and whether the software you use works well on its processor platform.

For someone who spends most of the day switching between browser tabs, documents, spreadsheets and video calls, 16GB RAM offers more breathing room. Someone who mainly uses a browser, edits documents and streams content may be comfortable with 8GB RAM, particularly if keeping costs down is the priority.

The Lenovo also offers a higher-resolution display, while the ASUS has a slightly larger screen. Neither advantage makes one laptop the automatic winner. Your workload, software requirements and the price available at the time of purchase should determine which one makes more sense.

Lenovo IdeaPad Slim 3X vs ASUS Vivobook Go 15: Price and Specifications

The Lenovo IdeaPad Slim 3X (2025) is listed at ₹66,600 on Amazon.in. It comes with a Snapdragon X processor, 16GB RAM, 512GB storage and a 15.3-inch WUXGA display. It is also a Copilot+ PC.

According to the Rufus price history provided, the Lenovo's price has ranged from ₹62,990 to ₹66,979 over the last 30 days. Its current price is therefore close to the upper end of that range.

The ASUS Vivobook Go 15 (2026) is listed at ₹51,948. It features a Ryzen 3 30 processor, 8GB RAM, 512GB storage and a 15.6-inch FHD display.

Its price history shows a wider range. Since the listing appeared on 4 August 2026, the price has ranged from ₹44,990 to ₹58,990, while the indicated offer price is around ₹47,448.

At the current listed prices, the difference is ₹14,652. That amount could matter more to a student or first-time laptop buyer than it would to someone who needs additional memory for daily work. It is also worth checking the final checkout price, since the ASUS has previously been available at a lower price and the Lenovo's current listing is near the top of its recent range.

16GB RAM vs 8GB RAM: How Much Difference Does It Make?

Memory is the biggest practical difference between these two configurations. The Lenovo has 16GB RAM, twice the ASUS's 8GB. That does not mean the ASUS cannot handle everyday tasks, but it does affect how much you can comfortably do at once.

Consider a typical workday. You might have Chrome open with several tabs, a document or spreadsheet running, a messaging app in the background and a video call in progress. An 8GB laptop can handle this kind of work, but the amount of memory available for each application becomes more limited as you add more tabs and programs.

When the system runs short of available RAM, Windows can use storage as virtual memory. However, an SSD does not replace physical RAM, and relying more heavily on virtual memory can affect responsiveness. The actual experience depends on the applications, background processes and workload.

With 16GB RAM, the IdeaPad Slim 3X has more room for multitasking. It is a more comfortable starting point for someone who routinely works across several applications, keeps many browser tabs open or expects their workload to become more demanding over time.

There is also a longer-term consideration. A laptop bought today may be used for several years, and the applications and services you use can become more demanding during that period. The extra memory gives you more flexibility without requiring you to move to a higher-priced configuration immediately.

That said, 16GB RAM does not automatically make the Lenovo the right choice for everyone. If your use is limited to web browsing, documents, streaming and occasional video calls, the ASUS's 8GB configuration may be sufficient. Paying ₹14,652 more for additional memory makes sense when you are likely to use it, not simply because a larger number looks better on a specification sheet.

Snapdragon X vs Ryzen 3 30: Which Processor Makes More Sense?

The Lenovo uses Qualcomm's Snapdragon X platform, while the ASUS Vivobook Go 15 is equipped with an AMD Ryzen 3 30 processor. Both can serve everyday computing needs, but the processor name alone does not tell you which laptop will perform better in every application.

The Snapdragon X is part of the Windows on Arm ecosystem and enables the Lenovo to qualify as a Copilot+ PC. That may appeal to buyers interested in compatible Windows AI features, but Copilot+ branding should not be the deciding factor unless those features are useful to your workflow.

The Ryzen-based ASUS offers a conventional x86 Windows environment, which can be a practical advantage for people who rely on older desktop programs, specialist software or utilities with specific compatibility requirements.

For browsing, Office work and video calls, the RAM difference may be more relevant to the day-to-day experience than the processor branding. However, performance in heavier applications depends on the specific software, workload and overall system configuration. I would not declare either processor the winner without comparing results for the tasks you intend to run.

The more important question is whether you need the Snapdragon X platform's capabilities and are comfortable with its compatibility considerations. If you do, the Lenovo becomes more attractive. If you prefer to minimise software compatibility concerns and mainly need an affordable Windows laptop, the ASUS has a clear case.

Windows on Arm Compatibility: What to Check Before Buying the Lenovo

The IdeaPad Slim 3X runs Windows on Arm. Many familiar Windows applications work on this platform, but support varies. Some programs have native Arm versions, while others rely on emulation or may have limitations.

This is particularly important if you use your laptop for work or study. A laptop can have enough RAM and a capable processor yet still be the wrong purchase if an essential application does not work as expected.

Before buying the Lenovo, check compatibility for any specialist applications you rely on, along with related drivers, VPN clients, peripherals and other utilities. If your college or employer requires a particular application, confirm that it works properly on Windows on Arm rather than assuming that every Windows program will behave identically.

This is the main consideration that could change my recommendation. If the applications I need are compatible, I would favour the Lenovo's 16GB RAM for multitasking. If an essential application is unsupported or unreliable on Arm, I would choose the ASUS instead.

15.3-inch WUXGA vs 15.6-inch FHD: Which Display Is Better?

The Lenovo IdeaPad Slim 3X has a 15.3-inch WUXGA display, while the ASUS Vivobook Go 15 features a 15.6-inch FHD panel.

WUXGA typically refers to a resolution of 1920 × 1200 pixels, compared with 1920 × 1080 pixels for standard FHD. This gives the Lenovo additional vertical workspace, which can be useful when reading long documents, editing spreadsheets or working with web pages.

The ASUS has a slightly larger display, but physical screen size is not the only factor that affects productivity. The Lenovo's extra vertical pixels may be more useful if you frequently work with text or documents.

However, resolution alone does not determine overall display quality. Brightness, colour reproduction, reflections and viewing angles also matter. If your work involves photo editing or using the laptop in bright environments, check the specifications of the exact panels before making a decision.

For everyday office work, both display sizes can be practical. The Lenovo's resolution is a useful advantage, but it should be considered alongside the other specifications rather than treated as proof that its display is better in every respect.

Is the Older Lenovo a Better Deal Than the Newer ASUS?

The idea that a previous-generation laptop can offer better value is not new. In this Reddit's r/laptops discussion about buying the latest hardware versus an older model, users discuss choosing older machines when they provide the right combination of specifications and price.

The principle applies to this comparison, but the model year is only one part of the decision. The Lenovo is a 2025 laptop with 16GB RAM, while the ASUS is a 2026 model with 8GB RAM. The newer machine does not automatically become the better purchase simply because it was released more recently.

At the same time, the Lenovo's higher memory capacity does not automatically justify its price. The ASUS may be the better value for someone whose workload is light and whose budget is limited. The Lenovo becomes easier to recommend when the extra memory provides a tangible benefit and its software compatibility fits the buyer's needs.

Price history adds another dimension. The Lenovo is currently listed near the upper end of its recent 30-day range, while the ASUS has previously been available at a lower price. If you are not in a hurry, checking the listings again before buying could help you decide whether to purchase now or wait for a more attractive offer.

The useful lesson is to compare the complete configuration, price and intended workload rather than buying by model year alone.

Which Laptop Would I Buy?

I would choose the Lenovo IdeaPad Slim 3X if I wanted a laptop for regular work or study, frequently multitasked and had confirmed that my applications worked properly on Windows on Arm. Its 16GB RAM is the main reason. The additional memory gives me more room to work across applications and makes the configuration more appealing for longer-term use.

However, I would not spend ₹66,600 just to get a Copilot+ PC or a newer-sounding processor. I would want the extra memory to make a meaningful difference to my workload, and I would check whether the Lenovo's price had improved before placing an order.

I would choose the ASUS Vivobook Go 15 if my budget stopped around ₹48,000–₹52,000 and I mainly needed a laptop for browsing, documents, online classes, streaming and other light tasks. Its 8GB RAM is a compromise, but it may be a reasonable one for someone who does not regularly run several demanding applications together.

The final decision comes down to two questions: will you benefit from 16GB RAM, and will your applications work properly on Windows on Arm? If the answer to both is yes, I would pay more for the Lenovo. If you need an affordable laptop for light use or prefer a conventional Ryzen-based Windows setup, I would save the money and choose the ASUS.

Whichever model you choose, check the final price, warranty coverage and return terms before ordering. For the Lenovo in particular, application compatibility should be confirmed before the return window becomes a concern.
