Computer RAM gets biggest upgrade in 25 years but it may be too little, too late — LPCAMM2 won't stop Apple, Intel and AMD from integrating memory directly on the CPU

Today’s computers use either SO-DIMM or Low-power DDR (LPDDR) RAM. LPDDR surpasses DDR5 in terms of speed and comes in a form factor that reduces power and footprint while enhancing performance. However, LPDDR memory isn't modular and must be soldered onto the motherboard, meaning replacing it for repairs or upgrades isn’t practical. 

CAMM is a new form factor for laptop RAM that has just been adopted by the JEDEC Solid State Technology Association and given the name CAMM2. This technology is thinner and faster than the SO-DIMM standard, promising a speed boost for future laptops. That’s not the only advantage to it though. 

LPCAMM2 harnesses the benefits of LPDDR5X components but in a modular form. This represents the first-ever access to a modular LPDDR-based memory solution, revolutionizing the field for designers and users. It will also be of particular benefit to data center operators, cutting down on energy consumption.

A future, not THE future

LPCAMM2 allows stacking up to 16 DRAM components within a single package, reducing memory architecture and saving space within laptops (the form factor takes up to 64% less space than a dual-SO-DIMM stack), paving the way for thinner, lighter laptop designs. 

Despite these advantages, LPCAMM2 requires a new type of socket, which increases cost. However, it serves as a single memory module designed to fill both memory channels (128 bits total), which will ultimately lead to cost savings down the line.

In theory, LPCAMM2 is an ideal memory solution but it will take a while to be fully adopted by laptop manufacturers. That's not the only obstacle it faces. Tech giants like Apple are hard-wiring memory into the processor, an approach which removes traditional bottlenecks and makes the RAM much more efficient. LPCAMM2’s arrival is great news, but it seems unlikely that it will halt or reverse this trend.

Windows Copilot leak suggests deeper assimilation with Windows 11 features

Key Windows 11 features may soon be customizable as Microsoft further integrates its Windows Copilot AI assistant into the operating system. This tidbit comes from tech news site Windows Latest , which claims to have discovered new .json (JavaScript Object Notation) files within recent preview builds of Windows 11. These files apparently hint at future upgrades for the desktop AI assistant. For example, a “TaskManagerService-ai-plugin.json” was found which is supposedly a “plugin for Task Manager integration”. If this ever comes out, it could give users the ability to “monitor or close running apps using” Copilot. In total, six are currently tested and they affect various aspects of Windows 11. Next, there is an “AccessbilityTools-ai-plugin.json” that gives Copilot a way to “control accessibility [tools]. This would make it "easier for those with [a] disability to navigate through the system.” Third is “ai-plugin-WindowsSettings.json” for controlling important Windows 11 set...

Google Chrome releases security fix for this major flaw, so update now

Google says it has fixed a high-severity flaw in its Chrome browser which is currently being exploited by threat actors in the wild.  In a security advisory , the company described the flaw being abused and urged the users to apply the fix immediately.  "Google is aware that an exploit for CVE-2023-2033 exists in the wild," the advisory reads. Automatic updates The zero-day in question is a confusion weakness vulnerability in the Chrome V8 JavaScript engine, the company said. Usually, this type of flaw can be used to crash the browser, but in this case it can also be used to run arbitrary code on compromised endpoints.  The flaw was discovered by Clement Lecigne from the Google Threat Analysis Group (TAG). Usually, TAG works on finding flaws abused by nation-states, or state-sponsored threat actors. There is no word on who the threat actors abusing this flaw are, though.

Samsung's ViewFinity S9 may be the monitor creatives have been searching for

Originally revealed during CES 2023 , Samsung has finally launched its ViewFinity S9 5K monitor after nine long months of waiting.  According to the announcement, the ViewFinity S9 is the company’s first-ever 5K resolution (5,120 x 2880 pixels) IPS display aimed primarily at creatives. IPS stands for in-plane switching , a form of LED tech offering some of the best color output and viewing angles on the market. This quality is highlighted by the fact that the 27-inch screen supports 99 percent of the DCI-P3 color gamut plus delivers 600 nits of brightness.  Altogether, these deliver great picture quality made vibrant by saturated colors and dark shadows. The cherry on top for the ViewFinity S9 is a Matte Display coating to “drastically [reduce] light reflections.”  As a direct rival to the Apple Studio Display , the monitor is an alternative for creative professionals looking for options. It appears Samsung has done its homework as the ViewFinity S9 addresses some of...
