AMD has revealed its first mobile gaming processor with 3D V-Cache. As the name suggests, 3D V-Cache enables AMD to stack more cache on top of the CPU. The tech arrived on desktop processors last year, and soon you’ll be able to pick up a laptop with a 3D V-Cache CPU.

This approach allows AMD to cram extra 64MB of L3 cache onto the Ryzen 9 7945X3D. For a total of 144MB. That helps mitigate the chances of cache miss. If your system can’t find information it’s looking for in the cache, it has to go to system memory. That could result in processes taking 10 times longer to carry out, according to AMD. The company claims its 3D V-cache approach can help increase the frame rates of games.

By moving vertically instead of padding more cache onto a CPU’s typical 2D plane, AMD is able to increase the size of the cache without having to make the chip wider or longer. In essence, the company can get more performance out of a CPU while avoiding any increase to the horizontal real estate it takes up on a motherboard.

The company claims this is the fastest mobile gaming processor on the planet, and that it’s more than 15 percent faster than the Ryzen 9 7945HX on average. It has 16 cores, 32 threads, up to 5.4 Ghz boost speeds and 55W+ TDP. The CPU is built on the Zen 4 architecture.

You won’t have to wait too long to get your hands on a laptop that uses the Ryzen 9 7945X3D. ROG’s Strix Scar 17 X3D machine will be available on August 22nd.

Google’s earthquake warning system for Android is supposed to provide notices in time to reach safety, but that might not have happened following the quake in Turkey on February 6th. BBC investigators claim that none of the hundreds of people they talked to in three Turkish cities received an alert before the first tremor hit. Only a “limited number” got an alert for a second tremor, investigators say.

We’ve asked Google for comment. Product lead Micah Berman tells the BBC millions of people in Turkey received earthquake alerts, although the company hasn’t shared data indicating widespread notifications. Google did show a handful of social media posts from people who said they received a warning, but only one was for the first quake. Berman says he doesn’t have a “resounding answer” as to why social networks were quiet about alerts, but does note the nature of a quake and the reliability of internet access can affect the system.

The Android Earthquake Alert System uses the accelerometer (that is, motion sensing) in phones to effectively crowdsource warnings. If many phones vibrate at the same time, Google can use the collective data to find the epicenter and magnitude of the quake, automatically sending a warning to people who are likely to feel the brunt of the shaking. While there’s no more than a minute’s notice, that can be enough time to find cover or evacuate. The technology can theoretically help people in areas where conventional warnings are unavailable.

The concern is that the system might have failed during a strong (7.8-magnitude) earthquake. Even if it worked, it’s not clear how many people should and do receive warnings in cases like this, not to mention milder incidents. Without more data, it’s not certain that Android’s quake alerts are reliable substitutes for traditional warnings over radio and TV.
