Thanks to a list in Futuremark SystemInfo, we have been able to know the specifications of the Core i7-8709G, an MCM solution (multi-chip module) that has an Intel CPU, a Radeon Vega GPU and 4 GB of HBM2 memory.
We already told you about the particular alliance between Intel and AMD to create this kind of solutions. We explained that we should not confuse them with APUs since in these the CPU and the GPU are in the same encapsulation and in the MCM we have an HBM2 processor, CPU, and memory in different packages mounted on the same PCB.
Clarified this we went to review the specifications of the Core i7-8709G. The CPU is a quad-core, eight-wire solution capable of high performance, as it is based on the Kaby Lake-G architecture.
For its part, the GPU is based on Radeon Vega M and has a bus of 1,024 bits, 4 GB of HBM2 at 800 MHz, which leaves us with a bandwidth of 204.8 GB / s. Its core works at 1.19 GHz, but we do not know the total count of shaders since the listing refers to “three graphic cores,” and so far the AMD graphics solutions have been divided into computing units (CUs) with 64 shaders each.
Even before the official presentation planned for the first quarter of 2018, information on the MCM processor (multi-chip module) Intel Core i7-8709G appeared on the Internet. Some of the features of this device have been identified with the help of Futuremark SystemInfo.
According to available information, the Kaby Lake-G MCM processor includes a 4-core processor module based on the Kaby Lake architecture and a module of the graphics subsystem AMD Radeon Vega M with dedicated HBM2 memory. According to Futuremark SystemInfo, the compute module supports the processing of 8 data streams and operates at a base frequency of 3.1 GHz, and the frequency in the Turbo Boost mode is 3.9 GHz.
The graphics core Radeon RX Vega M (694C: C0) operates at a frequency of 1.19 GHz. About the characteristics of the GPU information is no more, but some data about the memory subsystem are known. For the needs of a graphics core, 4 GB of HBM2 memory with a frequency of 800 MHz and a 1024-bit access bus are available. The memory bandwidth is 204.8 GB / s.
Returning to the processor, we have a frequency of 3.1 GHz in normal mode, and 3.9 GHz in turbo mode. If we make a general balance, we can make it clear that the Core i7-8709G is a very powerful solution that would be able to offer high performance at both CPU and GPU levels.
