The AMD Ryzen 7 3780U (Microsoft Surface Edition) is a System on Chip (SoC) processor that was launched as part of the ultra-slim 15-inch Surface Laptop 3. The processor has a Zen+ quad-core design that uses simultaneous multithreading to give 8 threads. This, including its 12nm processing technology, ensures an increase in the processor’s performance. Additionally, the AMD 3780U processor also has a dual-channel DDR4-memory controller for communication with RAM. It is connected to other computer components via PCIe version 3.0.
The Ryzen 7 3780U also features an integrated Radeon RX Vega 11 Graphics with a total of 11 GPU cores (computing units) with a GPU turbo boost of 1400MHz. This is where most AMD Ryzen 15’’ Surface Laptop 3 devices compete or differ from their Intel counterparts. The Ryzen 7 3780U is likely to compete with Intel’s U-series processor, which are most frequently used in Ultrabooks and convertible laptops.
The Radeon RX Vega 11 graphics card gives the Surface Laptop 3 devices much more than the typical level of graphical fidelity expected for a Windows 10 device. According to AMD, the integrated Radeon Vega 11 graphics is capable of driving modern AAA game titles. The visual capabilities of the Surface Laptop 3 are well beyond what could be expected from an equivalent Intel Core i5 device, and companies like Razer are creating accessories to take advantage of this technology.
The Ryzen 7 3780U, which operates at a base clock speed of 2.3GHz and a maximum boost clock speed of 4.0GHz and has an integrated Vega 11 graphics, is the fastest compared to the Ryzen 5 3580U, which has four cores running at 2.1 – 3.4GHz clock speed paired with Vega 9 graphics. Besides, both of these processors offer an extra one GPU core unlike their Ryzen 5 and 7 mobile counterparts, therefore, we expect to see a slightly improved performance for both processors at a nominal TDP of 15W. Both chips also have a configurable TDP-down of 12W and TDP-up of 35W to boost their operational performance with a maximum temperature of 105oC.
