AMD's Ruilong CPU,APU processor product line is increasingly complete and iterates steadily, and according to the latest exposure,AMD will launch a new APU, code name for ultra-low power mobile

AMD has launched a series of APU, such as Beema,Mullins,Kabini,Temash, for ultra-low power consumption, but there have been no products since the Reeydragon era, until now.


According to the roadmap and known intelligence, AMD will launch code names for mainstream desktops and mobile in the first half of next yea

Its process is upgraded from 12nm to 7nm, CPU architecture is upgraded from Zen to Zen 2, GPU architecture is still based on Vega, but will support the latest VCN 2.0 video decoding, DCN 2.1 display engine, even higher than Navi RX 5700 series, and support LPDDR4X-4266 memory for the first time.


AMD GPU Linux open source graphics driver has added initial support for Dali, including new ASIC IDs, voltage levels, andVerify that it is only a variant of Picasso in hardware, so it is still 12nm Zen architecture, and the GPU graphics core is based on Vega, and does not appear to have new display or video modules.

Such a design may seem backward, but it is understandable.After all, Dali APU is geared to ultra-low power mobile areas that are extremely cost-sensitive.For example, inexpensive notebooks, all-in-one computers, even thin clients, minicomputers and so on, the requirements for performance and function are not high.

Dali APU is also expected to appear in 2020.


Speaking of technology, this year is AMD 7nm versus Intel 14nm, but the latter also launched the 10nm processor Ice Lake, high-performance Ice Lake processor will go on sale next year, many people also know that Intel's 10nm process has improved considerably, the index does not lose the rival 7nm process, so what will be the competition between the two?

According to reports from Japanese media, AMD also compared the performance per watt of its own processors (mainly EPYC Xiaolong series) with that of its friends at an event in September, as follows:


It has to be admitted that the performance ratio of Intel process represented by blue is very strong before 14 nm node, and the progress of Intel is ahead of its rivals many years ago. The advantage of 14 nm over 28 nm used by AMD is obvious, and the gap between blue and green is quite large.

However, the situation is different since then. The Intel side has been grinding the 14nm process. The upgraded 14nm, the 14nm process per watt performance ratio is also improving, but the speed will certainly slow down, and the AMD side will be from 28nm to 14: 16 nm, 14: 12 nm, and the energy efficiency ratio will begin to reverse after the 12 nm node.

In terms of performance per watt, the second generation of AMD's EPYC this year uses 7 nm, which is already more energy efficient than the rival's 14nm process.

Later,AMD's third-generation EPYC processor Milan, which wants to launch the 7nm process, will also upgrade to the 10nm process, but the 7nm process is still a little higher than the 10nm in terms of performance per watt, which means that AMD is still in the lead in processor performance and energy efficiency.


Oh, by the way, Microsoft will launch its first 15-inch Surface Laptop 3 with an AMD processor at the Surface New Product Release on October 2.

WinFuture revealed that,Microsoft Surface Laptop 315 will provide three models based on the AMD platform, but unfortunately the specific model of AMD chip is not yet known.

It is reported thatSurface Laptop 315 may carry AMD Ryzen 5 3550H or Ryzen 7 3750H, which integrates AMD Radeon RX Vega GPU with strong performance.

In addition, it is uncertain whether Surface Laptop version 3.13.5 inches will also use AMD processors.

It is worth mentioning that Microsoft will release Surface Pro 7 on October 2, with the following specifications:

1. Surface Pro 7, Intel Core i3, 4GB RAM, 128GB SSD

2. Surface Pro 7, Intel Core i5, 8GB RAM, 128GB SSD

3. Surface Pro 7, Intel Core i5, 8GB RAM, 256GB SSD

4. Surface Pro 7, Intel Core i7, 16GB RAM, 256GB SSD

5. Surface Pro 7, Intel Core i7, 16GB RAM, 512GB SSD
