Microsoft says Windows 11 is 20% more responsive on 8GB as memory costs climb

Budget laptop buyers face a market where 8GB machines are making a comeback. Microsoft's claims decide whether those machines stay usable. PC makers and chip suppliers are already cutting specifications and warning of higher costs. That could keep device prices high into 2027. The gains are Microsoft's own lab figures. Tom's Hardware described the internal tests as conducted in favorable conditions.

Microsoft's 8GB claim

Microsoft published the numbers in a blog post on 3 November. It presented them as the payoff from a commitment it made earlier this year to improve Windows 11 performance. It says it took a three-pronged approach: use existing memory better, protect interactions that need to feel instant, and make key apps and Windows itself demand less memory.

The company says Windows can now keep up to 2GB more active data in memory. It does so rather than moving that data to storage. In practice, that should mean fewer reloads when you return to an app or a tab you left open.

Microsoft attributes the responsiveness gain to backing off background work such as search indexing while the machine is in active use. It says Edge now opens up to 33% faster. An Efficiency Mode for Microsoft Teams can be set to on by default. That mode improves launch times by 20%. Committed-memory growth in Edge and Microsoft 365 apps fell by up to 900MB, the company says. The memory footprint of Word, PowerPoint, Excel and Outlook dropped by 360MB. WhatsApp is already taking advantage of the improved memory management, according to Tom's Hardware.

The 40% multitasking figure comes from a demanding workflow. It uses 20 Edge tabs, a 4K video, large Word, PowerPoint and Excel files, Outlook and File Explorer, opened one after another. ZDNET reported that users need the latest Windows 11 26H2 build to see the changes.

Why 8GB is back

Microsoft's push follows a resurgence of 8GB RAM laptops this year. It also follows a global PC component shortage that is forcing manufacturers to lower specifications.

At Apple, chief executive John Ternus told the company's 2 November earnings call that memory pricing was "unprecedented". Apple expects memory costs in the December quarter to be even higher than in the previous three months. Its manufacturing bill has climbed by $33 billion in just a few months, Tom's Hardware reported, citing Reuters. Apple shares fell 2.75% in after-hours trading.

Apple has already raised prices. It raised prices for Mac and iPad at the end of June, and for iPhone in September. Ternus said that provided "some offset".

Intel's client computing group told a similar story. Revenue fell 5% year over year to $8.1 billion in the third quarter of 2026. The company cited industry-wide memory shortages on its earnings call. Intel expects the PC slowdown to continue at least through the first half of next year. It expects memory and NAND pricing pressure to persist into 2027.

The AI memory squeeze

AI infrastructure demand sits behind the consumer squeeze. Huawei is telling some customers to source memory for its AI chips themselves, The Information reported. That effectively pushes buyers toward the black market. The company plans to launch the Ascend 960DT early next year. But its Chinese suppliers cannot produce enough HBM. U.S. export rules also block direct purchases from Samsung and SK Hynix.

Smugglers bundle HBM with cheap server processors that fall below the export threshold. They ship the packages through Hong Kong, where workshops separate the two. Prices for smuggled HBM3E have jumped from a few hundred dollars to around $4,000 per unit in a year, according to a Shenzhen broker cited by The Decoder. Each AI chip needs six to eight units. So memory alone can cost up to $32,000.

Samsung and SK Hynix control over 80% of global HBM market combined.

What happens next

Microsoft also says it plans to make memory compression smarter. It plans to share common parts between Windows features and apps. It plans to work with PC makers and silicon vendors to reduce the memory a PC must reserve for its hardware. WinUI 3 apps such as File Explorer and Notepad will be designed to use less memory and open faster, according to the company.
