    The Asus Zenbook S 14 has got the typical trade-offs that the thin and light laptops always have. Unfortunately, to address the flaws of the laptop, a thicker chassis would be needed. It will however be interesting to see what competing brands have to offer.

    The most important thing I see is that Lunar Lake is a major architectural update – larger than usual. It makes a case that the Snapdragon, with its compatibility issues with ARM vs x86 is a tougher sell. Lunar Lake has very good battery run times and is quickly closing the gap with Apple, which is the current laptop battery life champion.

    Intel will also be releasing the higher performance Arrow Lake, which is expected later this quarter and AMD will be releasing the Strix Halo, which are higher performance Zen 5 parts.

    It will be interesting to see how the other laptops using this generation do. The other big thing we will have to wait for in 2025 for the higher performance laptops is that Nvidia is widely expected to refresh its entire GPU lineup.

      Strix Halo with a 256-bit memory controller is not designed for thin laptops, despite the advanced process technology. The minimum PL1/PL2 will obviously exceed 45W and is designed for large and heavy gaming or professional business-class laptops.

      I already wrote that I was extremely shocked by the extremely low multi-threaded performance of Lunar Lake allegedly made on TSMC's "3nm". For such a process technology, this is a pure EPIC FAIL for the Intel team, especially against the background of the comparisons provided by the author (thanks to him for such detailed reports) with AMD Zen4 Phoenix/Zen5 at approximately the same level of consumption, which are made on the less efficient TSMC process technology – "4nm". In fact, AMD, even at the level of the outdated Zen4, killed Intel outright in terms of who is now the undisputed technological leader in x86.

      In general, Lunar Lake can only offer a slightly more advanced igpu, but who is interested in this among buyers? It is still not capable of providing smooth gaming even with 4-5 year old releases in High/Ultra quality and at least 60 fps without drops. That is, dgpu is still required. In terms of business graphics/3d and performance, even the outdated Zen3 is more than enough, not to mention Zen4 Phoenix and Zen5 Strix Point.

      It should be noted that Intel again deceived consumer expectations and did not add an integrated Thundebolt 5 controller to the Lunar Lake chips, which doubled the bandwidth available to the eGPU. Which is also a complete disappointment. And also the ability to connect 8k monitors to a laptop in lossless mode. Which we have all been waiting for on the market with text (and graphics) quality close to that of laser printers, even on 32" diagonals. It should be noted, however, that AMD laptop manufacturers have also been doing this obscenity for 2 years now, since Zen4 Phoenix and Zen5 have 2 USB40 ports built in, but they are often missing from laptops.

      Even the memory controller and its built-in memory, for the first time in the recent history of Intel vs AMD (since about 2015), Lunar Lake can no longer offer anything special compared to Zen5, the difference has become minimal in terms of bandwidth – less than 8GB/s on average, as well as in terms of latency (it would be nice to explore this in more detail in reviews). Moreover, Intel works directly with the memory built into the chiplet and it operates at a higher frequency than Zen5 – 8500 vs 7500!

      This is simply a systemic collapse of the Intel development team. It looks like they are rapidly losing human capital within the company.

      But all buyers should remember one sad thing – the ratio of production and sales of mobile and desktop Intel processors to those from AMD is still about 5:1. Which determines the real situation in the retail market for both PCs and laptops. We, buyers, all over the world, are still sadly observing the utter shortage of laptops with advanced AMD processors, just like a year ago, just like 2 years ago, just like 3 years ago. Nothing much is changing in the x86 camp. Intel, despite the complete and already unconditional loss of its "blue" team of developers of the status of a technological leader, having even received access to the latest TSMC technological process, will still, even on TSMC, apparently have much more weight in terms of capturing TSMC resources than AMD, which has clearly and for many years not been eager to significantly expand its market share of x86, for which there are also objective reasons (lack of cash reserves for dumping the first years of redistribution of the market share of the x86 market)

      Although, of course, the forced switching to TSMC plants will give Intel a significant reputational and even greater financial damage. As a number of analysts are already saying – it was a mistake.

      Buyers can only hope that in 2025, with the clearly growing global deficit in laptops with advanced chips already in both x86 teams, they will find at least one laptop model that suits them in terms of characteristics and comfortable in ergonomics, with an adequate price for them…
