AMD claimed that the Ryzen 7 2700U is the fastest processor for ultrathin notebooks, with 44 percent more multi-threaded CPU performance and up to 161 percent more graphics performance than the competition. The difference is Intel's processors use a "refreshed" version of the seventh-generation Kaby Lake architecture and a rebranded version of the graphics processor that gains most of its improvements through the addition of a couple of cores and some tweaks.
For now, AMD will launch two low-power SKUs, the Ryzen 7 2700U and the Ryzen 5 2500U, both which use four Zen CPU cores with eight threads, paired up with 512KB of L2 cache per core and 1MB of L3 cache per core, for a total of 6MB of L2/L3 cache.
Implementing only a single CCX is an important step forward for reducing power consumption enough to lower temperatures and fit Ryzen into slim devices.
For its own part, AMD claims that the new Ryzen chips will offer dramatically improved performance over its own last generation of laptop chips, with up to 200 percent more CPU performance (for multicore use) and up to 128 percent better GPU performance, although AMD's last generation of chips weren't exactly computational powerhouses to start. Up to 2400 MHz DDR4 RAM is supported in a dual channel configuration, although some OEMs may resort to running only a single channel. Mobile Extended Frequency Range (mXFR) raises sustained performance in notebooks with great cooling solutions and certified for "Ultimate XFR Performance". This potentially allows for better power savings and, depending upon the applications you run, better performance. We see the exact same core and thread count in the Ryzen 5 2500U, only with a max clock speed of 3.6GHz instead of 3.8.
Apple Says Bloomberg Report on Face ID Seeing Reduced Accuracy "Completely False"
I think most would forgive Apple the notch were it not for the iPhone X's suspicious reliance on facial recognition for log-in. Exactly how much the efficiency and performance of Face ID have decreased as a result of the new specifications is unclear.
In terms of efficiency, Ryzen Mobile has come in above expectations.
Not to forget, the new Ryzen Mobile processors also offer longer battery life than their predecessors. Compared to just three years ago, Raven Ridge is almost six times more efficient than Kaveri which launched in 2014.
