1、 The Ruilong 4000 series notebook that day and night look forward to finally arrive!

If there had been no accident, the new generation of sharp dragon 4000 series mobile APU should have met you earlier. This period of time seems like a long wait, but such a revolutionary product that is enough to ignite the PC industry is finally coming!

Since the release of the first generation of the sharp dragon processor in March 2017, AMD's share has been rising for 10 consecutive quarters, and it is very good and popular in the field of DIY. However, up to now, it has not only occupied about 20% of the overall PC market share, the most critical reason is that the sales volume of the sharp dragon notebook is too large compared with that of its competitors.

But it doesn't matter. All of this will change with the arrival of the sharp dragon 4000 series mobile APU!


In terms of specifications, Renoir APU can have at most 2 CCX, that is, 8 CPU cores and 8 Cu units (512 stream processors). It's a pity that the PCIe version is still 3.0, with 16 connections in total. 8 connections are displayed separately, and the other 8 are distributed by notebook manufacturers themselves.

In addition, Renoir APU can natively support type-C and USB 3.1.


Each CCX of Renoir APU is still 4 cores, 2MB L2 cache, but the level 3 cache is only 4MB, only 1 / 4 of the desktop zen2 processor. Amd should also do this in order to control the core area and reduce power consumption.


The memory controller supports both lpddr4x and DDR4. The former can reach lpddr4x-4266, while the latter supports ddr4-3200 natively, which is the same as the desktop version. Dual channel lpddr4x-4266 brings up to 68.3gb/s of memory bandwidth, which can provide great help for the performance improvement of Renoir APU game!


At present, there are 6 types of sharp dragon 4000 series standard pressure processors released. The Asustek Tianxuan notebook we received is equipped with sharp dragon 7 4800h processor. Based on TSMC 7Nm process technology, it has 8 cores and 16 threads, basic frequency of 2.9ghz, and acceleration frequency of 4.2ghz at most. As for the highest full core frequency, although amd has not released it, according to our test, it should reach 8 cores and 4.1ghz.

In the GPU part, there are 7 Vega Cu units, a total of 448 stream processors, with a frequency of 1600MHZ. In terms of performance, it can face the 25W version of full blood mx250 independent graphics card.

The TDP of the sharp dragon 7 4800h processor is 45W, the adjustable range (CTDP) is 35W ~ 54W, and another short-time power consumption (PPT fast) is 65W (lasting for 5 seconds).
