If amd had not released the sharp dragon processor, consumers would never have thought of buying a computer with excellent performance and acceptable quality, which would not have cost so much. In 2018, the price of a mainstream light and thin version needs to be more than 5000 yuan. But now, if you buy a mainstream light and light version, the price is less than 4000 yuan. The times have really changed. < / P > < p > at the price of 3000-4000 yuan, most of them use amd sharp dragon processor, and they are cheap and light-weight books with 8GB or 16GB and 512gb solid-state disks. If the same notebook if Intel or amd two platforms version, then amd sharp dragon version will often be cheaper than 1000 yuan. However, this will lead to a misunderstanding, that is, consumers think that the notebook equipped with AMD processor should be cheap, that is, it is a cheap product. If you buy a high-end notebook, you should buy an Intel platform. < / P > < p > however, this is not the case. After various tests, this generation of AMD sharp dragon 4000 series processor has a much higher energy consumption ratio than the core processor, and has more cores and stronger comprehensive performance. < / P > < p > in addition, software vendors are constantly optimizing the performance of AMD sharp dragon processors. Amd sharp dragon processors are more suitable for high-end lightweight books with limited cooling effect than Intel. < / P > < p > if there is anything wrong with AMD sharp dragon processor, it is that it must be combined with high-frequency memory to fully play its due performance. And it does not support lightning 3 interface. < / P > < p > for example, redmi and glory only provide 2666mhz memory for AMD sharp dragon processor, and the performance is definitely lower than Lenovo’s new series notebook with 3200mhz memory. However, the good news is that manufacturers are also trying to move amd processors away from the low-end entry-level position and put them on the medium and high-end products. Lenovo, HP and ASUS have similar products. < / P > < p > in fact, this product can be regarded as a sharp dragon version of the yoga s740, with the same shape. As the positioning of yoga in Lenovo’s product line is higher than that of Xiaoxin series, both the workmanship and configuration of products will be higher. < / P > < p > last year, the ThinkPad x395 equipped with a sharp dragon processor has a very high performance price ratio, and the price was even lower than 4000 yuan some time ago. For ThinkPad X series products, it is valuable. < / P > < p > as I mentioned before, this book is one of the few products with cost performance in ASUS lingyao series. After all, ASUS lingyao is also a medium and high-end lightweight product line. < / P > < p > the biggest selling point is the light and compact fuselage. The thickness of the whole machine is 13.5mm and the weight is 1.2kg. The battery capacity is 67wh, which is larger than the above models. < / P > < p > at the same time, this book has passed the test of mil-std-810g standard, which is very rare for a thin and thin book with narrow frame. < p > < p > this should be HP’s second model worth buying in addition to the 663. HP’s envy X360 13 has always been used as the AMD sharp dragon processor. In this generation, it has finally turned over, but the memory does not have the option of 16GB, which is a pity. < / P > < p > as a 360 degree flipped notebook, this generation of envy X360 13 narrows the screen chin and looks a little more harmonious. The screen is still a touch enabled 1080p 13 inch 72% NTSC panel, but the pen will be purchased separately. < / P > < p > this book does not support usb-c charging. The thickness of the whole machine is 16.4mm and the weight is 1.32kg. HP has proved that usb-a interface can be flat, so other manufacturers should not make excuses not to give usb-a ports.
