AMD's latest laptop CPUs include its first chips for Chromebooks
AMD is kicking off 2019 with an overhaul of its laptop processors, and it's breaking some new ground in the process. The company has unveiled its first two A-Series chips designed explicitly for Chromebooks, the 1.6GHz A4-9120C and 1.8GHz A6-9220C. Both are dual-core chips that use just 6W of power and promise faster performance than the Intel chips you typically see in entry-level Chrome OS portables. The A6 is up to 23 percent faster in web browsing than the Pentium N4200, AMD said, and 42 percent faster in photo editing. You might not have to spend a small fortune to get a Chromebook with decent horsepower.
AMD returns to high-end gaming CPUs with Ryzen 7
AMD has largely ceded the performance processor space to Intel in recent years. You typically get one of its chips inside a budget PC, not an all-out gaming rig. At last, though, you might have reason to get excited: AMD is launching Ryzen 7, a desktop CPU line based on its much-ballyhooed Zen architecture. The key is a dramatic improvement in the number of instructions the chip can handle at once. A Ryzen 7 CPU can do 52 percent more work every cycle than a similarly-clocked predecessor thanks to a newer 14-nanometer manufacturing process, five times the bandwidth and some overdue architectural upgrades. This is AMD's first processor with simultaneous multithreading (Hyper-Threading in Intel speak), so each core can execute two code paths at the same time.
