    Last year, Google CEO Sundar Pichai announced that the company had invested heavily in hardware and had drawn up a comprehensive roadmap for 2021. Following this statement, several speculations were raised, and some experts predicted that Google would seek to develop the chips needed for the Pixel and Chromebook phones by entering the chipset space. According to recent leaks, Google is developing a new chipset. This chipset is known internally as the Whitechapel GS101 and is supposed to be used in the construction of the Pixel 6 smartphone and another device - which will probably be introduced in the fall. What we know of the Whitechapel GS101 to date is Google's first experience in chipset production

    Whitechapel (meaning "white shrine") is the code name that Google will use to name its chips (like the code name "Snapdragon" on Qualcomm chipsets). GS is also probably abbreviated to Google Silicon. Google used SLSI (a subsidiary of Samsung) to build the chip, and the GS101 is apparently made with Samsung's 5-nanometer lithography. Most Samsung phones (except those imported to the United States) use the Exynos chip, which is also made by SLSI. With that said, we can predict that the Whitechapel series of chips (at least initially) has a lot in common with the Exynos series. Here are more details about this chip:

    So far, most smartphone chips have been designed with two big.LITTLE clusters, in which the cluster with weaker cores takes lighter processing and in processing Heavier clusters with stronger cores also help the chipset. But rumors surrounding the GS101 suggest that the chip's CPU uses three clusters; A dual-core cluster consisting of Cortex-A78 cores, a dual-core cluster consisting of Cortex-A76 cores, and finally a quad-core cluster consisting of Cortex-A55 cores. However, despite Whitechapel's close relationship with Exynos, no Exynos chips have yet been produced with this architecture.

    The flagship Snapdragon 888 and Exynos 2100 chips also feature three clusters, with the exception that both have a single-core cluster containing the powerful Cortex-X1 core. Thus, the new GS101 chip, despite having three clusters, does not reach the Snapdragon 888 or Exynos 2100 in terms of processing power. According to some experts, the GS101 will see performance at the level of an upward-moving mid-chip; Something like the Snapdragon 765 used to make the Pixel 5.

    The GS101 chip apparently has a graphics processing unit based on the Valhall architecture (ARM product). It should be noted that so far limited GPUs have been built with Valhall architecture, among which we can mention the flagship GPUs Mali-G77 and Mali-G78 as well as the intermediate GPU Mali-G68. On this account, we will see a significant change in the standard adopted in the United States; Where phones made with Snapdragon chips - including Pixel phones - use Adreno (Qualcomm) GPUs. The Adreno series usually outperforms the Mali series, but benchmark scores comparing the Exynos and Snapdragon versions of the Galaxy S21 Ultra suggest that the Adreno 660 GPU (on the Snapdragon 888) and the Mali-G78 GPU (on the Exynos 2100) ) Have almost the same performance.

    Last year's rumors about Whitechapel suggested that the project's first chip would use a Pixel Visual Core and an NPU (neural processing unit). If these rumors are true, the Pixel 6 - which comes with the GS101 - will see the return of the Pixel Neural Core as integrated with the hardware (not as a separate chip).

    According to some informed sources, the GS101 chip uses a new security chip called Dauntless. According to our knowledge of Chromium source code, Dauntless is a chip that can work on devices running Android and Chrome OS. Also, Dauntless is likely to replace Titan-M chips in older pixels, except that in the Pixel 6, the Dauntless chip will be integrated directly into the GS101.

    A modem is a piece of hardware that connects a device to an operator. Without a 5G modem, your phone cannot connect to the fifth generation network. The modem can be a completely separate part of the smartphone chip. The best example of this is the Snapdragon 865, which lacks a built-in modem and is flanked by a separate fifth-generation X55 modem. According to some informed sources, the modem used in the Pixel 6 will be in the style of the Shannon modem in Exynos chips. Of course, it is not clear whether this is for the US market only or for other markets.

    Google's attempt to build a native chip may be an exaggeration, and it is unlikely that we will see headlines like this: "Google ready to compete with Apple!". But the fact of the matter is that, at least in terms of chipset and smartphone production, comparing Apple to Google is not the right thing to do. Apple is a $ 2 trillion hardware company, and the iPhone is its biggest product. While Google is primarily an advertising company, the hardware part of the company - which makes pixel phones - is just a small, side project for Google.

    It can be said that the most important benefit of chip production by Google is the increase in update time. It is much easier to get Android updates when your smartphone has the support of its chipset maker. But after three years, Qualcomm abandons its chipsets and does not take any action to upgrade the device's operating system. This lack of Qualcomm support makes it extremely difficult to update. If Google eliminates the need for Qualcomm chipsets, it can implement the 5-year Android update policy on Pixel phones (just like the policy Apple has adopted for its iPhones).

    Except for updates, no more can be expected from Whitechapel. It is interesting to know that many manufacturers of Android phones have produced chipsets for their phones, but their success rates are different. These include Samsung's Exynos chips and Kirin chipsets from Silicon (Huawei). Xiaomi launched the Surge S1 chip in 2017, and we recently saw the release of the Surge C1 chip in the new Mi Mix Fold. Oppo is also developing its own chipsets.

    None of these efforts have been as successful as Qualcomm's, and most of these companies (except Huawei) prefer Qualcomm chipsets to their own chipsets in their flagship handsets. Interestingly, all chipset manufacturers - including Qualcomm - design their CPUs based on what ARM has drawn. However, there should be no significant difference between the CPUs of the accompanying chipsets. Therefore, the main difference between the chipsets is related to the type of GPU and the modem used in them. In these two areas, Qualcomm has done better than others, which is why most smartphone makers prefer to use the company's chipsets in the production of their products.
