Microsoft introduced the Surface Laptop 3 hybrid yesterday. It will be available in versions with a 13.5-inch and 15-inch display, and the latter is equipped with a custom AMD Ryzen processor, which was developed in collaboration with AMD and Microsoft specifically for this device.
The processor is called AMD Ryzen 7 3780U Microsoft Surface Edition, which emphasizes the fact that it will be used exclusively in Microsoft Surface products. In fact, the new product is an improved version of the Ryzen 7 3700U processor. According to AMD, the Ryzen 7 3780U is its fastest processor for ultra-thin laptops, and it gives the Surface Laptop 3 outstanding performance and allows the laptop to run on battery power all day.
The Ryzen 7 3780U processor has four Zen cores and eight threads, and its clock frequency reaches 4 GHz. It is noted that the new product is able to fine-tune the clock frequencies in order to ensure the optimal balance between performance and energy efficiency. By the way, the standard TDP level of the new processor is 15 watts, but it can be increased to 25 watts if necessary.
Much more significant changes have been made to the integrated graphics of the new Ryzen 7 3780U – Vega 11 is used here, which has 11 computing units (Compute Unit, CU), which means the presence of 704 stream processors. This automatically makes the new product an AMD mobile processor with the most powerful integrated graphics – the rest have no more than 10 blocks.
Moreover, according to AMD, this processor has the most powerful integrated graphics among all mobile chips in the world. In confirmation of these words, the test results of the new items in the 3DMark11 Performance and 3DMark Timespy benchmarks are presented. In them, the new Ryzen 7 3780U was able to get ahead of the Intel Core i7-1065G7 generation of Ice Lake by 4% and 8% respectively, and the advantage over the 9th generation Intel mobile chips with Intel UHD 630 graphics is 129-154%. Also, the new product was able to get ahead of the Ryzen 7 3700U by 15-16%.
In the end, we note once again that the Ryzen 7 3780U was developed specifically for Microsoft and clearly will not appear on devices from other manufacturers. However, this is definitely a great success for AMD, which is just beginning to “win back” the mobile market segment from Intel. In the future, it is very likely that other custom AMD mobile processors may appear, for example, for future Apple MacBook Pros.
