Internal Components - Part 3

In order to access the component side of the motherboard, we had to remove it from the chassis. Figure 17 displays the motherboard, with the memory sockets at the lower right, the GPU cooler at the left and the CPU cooler at the right. As you can see, the GeForce 765M chip and the video memory are soldered on the mainboard, not on an independent video card.

The MSI GS70 STEALTH has two memory sockets, populated with two Elixir DDR3-1600 8 GiB modules, for a total of 16 GB, which is the maximum amount of memory the laptop supports.

Figure 19 shows the motherboard of the MSI GS70 STEALTH with the coolers removed. You can see the video section at the left, with four SAMSUNG K4G20325FD-FC04 GDDR5 memory chips for an amount of 2 GiB of memory, running at 4 GHz and accessed through a 128-bit bus. It means the video chip accesses memory with a bandwidth of 64 GB/s.

The Intel Core i7-4700HQ, with four cores (eight virtual cores thanks to the HyperThreading technology), 2.4 GHz (3.4 GHz maximum turbo clock), and 6 MiB cache memory, can be seen at the right, also soldered onto the motherboard.

The audio interface is generated by the chipset using the Realtek ALC892 codec, which is a good solution, providing a 97 dB signal-to-noise ratio for the analog outputs, 90 dB signal-to-noise ratio for the analog inputs, and up to 192 kHz sampling rate for both inputs and outputs, with 24-bit resolution. These specs are good for the mainstream user, but not enough if you are looking into working professionally with audio editing.
