Lenovo IdeaPad Slim 3 Gen 8 15.6" (Core i7-13620H / 16GB RAM / 256GB) VS Samsung Galaxy Book5 15.6"

In terms of design features, the Lenovo IdeaPad Slim 3 Gen 8 and the Samsung Galaxy Book5 are completely evenly matched across every tracked specification. Both laptops lack a backlit keyboard, a fanless design, weather sealing, and a rugged build.

The absence of a backlit keyboard on both devices is a notable omission for users who frequently type in low-light environments, as it is a feature increasingly common even at mid-range price points. Similarly, neither machine offers any weather resistance or ruggedized construction, meaning both are standard consumer laptops best kept away from harsh conditions.

Given that every tracked design attribute is identical between the two, this group results in a tie. Neither product holds any design advantage over the other based on the available data, and prospective buyers should look to other specification groups to differentiate between them.

Both the Lenovo IdeaPad Slim 3 Gen 8 and the Samsung Galaxy Book5 share a 15.6″ screen with a 1920 x 1080 Full HD resolution, a 60Hz refresh rate, anti-reflection coating, and support for up to 4 external displays. The resolution listed for product_1 appears in transposed order in the raw data but represents the same 1080p standard, so in practice these two panels are functionally identical across every measurable display attribute provided.

At 60Hz, both laptops are tuned for everyday productivity and media consumption rather than gaming or fast-motion content, where higher refresh rates like 120Hz or 144Hz would deliver noticeably smoother visuals. The shared anti-reflection coating is a practical win for anyone working near windows or under bright office lighting, reducing eye strain and glare without requiring additional accessories.

With no differentiating factors present in this spec group, the display category is a tie. Users prioritizing display quality or versatility will need to evaluate other aspects — such as panel type or brightness — that fall outside the provided data.

This is where the two laptops diverge meaningfully. The Samsung Galaxy Book5 holds a significant architectural advantage with its 3nm semiconductor process versus the IdeaPad Slim 3′s 10nm chip. A smaller process node generally translates to better power efficiency and thermal headroom, which directly enables the Galaxy Book5′s higher 5.2GHz turbo clock speed compared to 4.9GHz on the Lenovo. For users running demanding workloads — video editing, compilation, large spreadsheets — that extra headroom matters in sustained performance scenarios.

The GPU difference is equally striking: the Galaxy Book5′s integrated graphics reach a turbo of 2100 MHz versus 1500 MHz on the IdeaPad, a 40% gap that will be felt in light gaming, video acceleration, and any GPU-assisted creative task. The Galaxy Book5 also supports DirectX 12 Ultimate rather than standard DirectX 12, unlocking advanced rendering features like hardware ray tracing — relevant for modern games and some professional visualization tools. On the storage side, the Galaxy Book5 ships with 512GB versus just 256GB, offering meaningfully more room for files and applications without requiring an immediate upgrade.

The IdeaPad Slim 3 does edge out the Galaxy Book5 in raw CPU thread count (16 vs 14), which could offer a marginal advantage in highly parallelized workloads, but this is a narrow lead that the Galaxy Book5′s faster turbo and more efficient architecture largely offset. Overall, the Samsung Galaxy Book5 holds a clear performance edge in this group, driven by its superior GPU clock, higher turbo speed, more modern process node, and doubled storage capacity.

The PassMark results reveal a nuanced split between these two machines. The Lenovo IdeaPad Slim 3 Gen 8 posts a substantially higher multi-core score of 23,805 compared to the Galaxy Book5′s 18,555 — a gap of roughly 28%. In practical terms, multi-core performance governs tasks that can spread work across multiple CPU cores simultaneously, such as video encoding, compiling code, running virtual machines, or handling heavy multitasking. For users who push their laptops with these kinds of workloads, the IdeaPad holds a decisive real-world advantage.

The single-core story flips the result. The Samsung Galaxy Book5 scores 3,732 in the single-core test versus 3,569 on the IdeaPad — a narrower but meaningful ~5% lead. Single-core speed governs the responsiveness of everyday tasks: launching apps, browsing, typing, and most general productivity software. A snappier single-core score means the Galaxy Book5 may feel slightly more fluid in day-to-day use, even if it falls behind under heavy sustained loads.

Which result matters more depends entirely on the user′s workload. For content creators, developers, or power users, the IdeaPad Slim 3 Gen 8 has a clear benchmark edge. For the typical user whose priority is general responsiveness, the Galaxy Book5′s single-core lead keeps it competitive. On balance, the IdeaPad takes the advantage in this group due to the larger and more impactful margin in multi-core performance.

The connectivity profiles of these two laptops are largely similar, but two ports set them apart in opposite directions. The Samsung Galaxy Book5 includes a dedicated RJ45 ethernet port, which the IdeaPad Slim 3 lacks entirely. For office users, remote workers on unreliable Wi-Fi, or anyone connecting to a corporate network, a wired ethernet connection offers superior stability and speed — making this a meaningful practical advantage for the Galaxy Book5.

The IdeaPad counters with a VGA output, an older analog display connector absent on the Galaxy Book5. While VGA is largely obsolete in modern setups, it remains relevant in environments with legacy projectors or older conference room displays — a niche but real use case in certain business or educational settings. Users in those environments would otherwise need a dongle with the Galaxy Book5.

Everything else — HDMI, USB Type-C, Wi-Fi, external memory slot — is shared equally between the two. The absence of Thunderbolt and USB4 on both machines is also worth noting for users expecting high-speed external device ecosystems. On balance, the Samsung Galaxy Book5 holds the edge in this group: a built-in ethernet port is a more universally useful addition than VGA, which serves a shrinking audience.

Battery capacity is a clear differentiator here. The Samsung Galaxy Book5 packs a 61.2 Wh battery compared to just 47 Wh in the IdeaPad Slim 3 — a roughly 30% larger cell. All else being equal, a bigger battery directly translates to more hours between charges, making the Galaxy Book5 the stronger choice for users who spend long stretches away from an outlet, whether commuting, traveling, or working in meetings.

The IdeaPad offers a practical counterpunch with its sleep-and-charge USB ports, which allow connected devices like phones or earbuds to charge even when the laptop itself is powered off or in sleep mode. The Galaxy Book5 lacks this feature. For users who rely on their laptop as a charging hub throughout the day, this is a genuinely useful convenience that partially offsets the battery capacity gap.

Neither laptop supports a MagSafe-style magnetic power adapter, so both rely on standard charging connectors. On the whole, the Samsung Galaxy Book5 holds the advantage in this group — a 30% larger battery is a substantial real-world benefit that outweighs the IdeaPad′s sleep-and-charge convenience for most users prioritizing unplugged endurance.

Most of the feature set here is shared equally — stereo speakers, a 3.5mm audio jack, dual microphones, and a front camera are present on both laptops. Neither machine offers ray tracing, DLSS, GPS, or motion sensors, which is expected at this product tier. The meaningful separation comes down to just two features, both exclusive to the Samsung Galaxy Book5.

First, the Galaxy Book5 includes Dolby Atmos support, which applies audio processing to enhance spatial sound on the built-in speakers and through headphones. For users who consume a lot of media — streaming, video calls, or casual music listening — this can produce a noticeably more immersive audio experience compared to the IdeaPad′s unenhanced stereo output. Second, the Galaxy Book5 adds a fingerprint scanner, enabling fast and secure biometric login without typing a password. The IdeaPad Slim 3 offers neither of these, relying entirely on traditional authentication methods.

These are not transformative omissions on the IdeaPad, but they are consistent quality-of-life advantages. The Samsung Galaxy Book5 takes the edge in this group — its fingerprint scanner and Dolby Atmos support add everyday convenience and a richer audio experience that the IdeaPad simply does not match.

The single most revealing figure in this group is the Thermal Design Power (TDP): the IdeaPad Slim 3 Gen 8 operates at 45W while the Galaxy Book5 is rated at just 15W. TDP represents how much heat a processor generates under sustained load, and by extension how much power it consumes. The IdeaPad′s higher TDP explains its multi-core benchmark lead — it is simply running a more power-hungry chip. The Galaxy Book5′s 15W envelope, however, is a core reason why it can sustain better efficiency, run cooler in everyday use, and support that larger battery runtime discussed in the battery group.

The Galaxy Book5 also pulls ahead on memory bandwidth, with a maximum RAM speed of 8400 MHz versus 5200 MHz on the IdeaPad. Faster RAM reduces bottlenecks between the CPU and memory, which benefits tasks like large data processing, video editing timelines, and GPU-intensive workloads that rely on integrated graphics. Additionally, the Galaxy Book5′s instruction set includes AVX2 — an extension not listed for the IdeaPad — which accelerates specific mathematical and media workloads in compatible software.

Shared attributes like big.LITTLE architecture, dual memory channels, integrated graphics, and identical OpenCL/OpenGL versions keep both machines on common footing for general compute tasks. But the standout takeaways here favor the Samsung Galaxy Book5: its dramatically lower TDP points to a more efficient, thermally manageable design, and its significantly faster RAM ceiling gives it a structural memory bandwidth advantage that complements its modern processor architecture.
