What we know so far from Whitechapel GS101 is Google’s first experience in chipset production
Whitechapel (meaning “white chapel”) is a code name that Google will use it to name its chips (like the codename “Snapdragon” in Qualcomm chipsets). GS is probably short for Google Silicon. Google received help from SLSI (subcategory of Samsung) to make this chip. GS101 is apparently made with Samsung’s 5nm lithography. Most Samsung phones (except those coming to the US) use the Exynos chip, and this chip is also made by SLSI. Having said that, it can be predicted that the Whitechapel series of chips (at least initially) will have a lot in common with the Exynos series. In the following, we will review more details of this chip together:
So far, most smartphone chips are made with big.LITTLE two-cluster design, where the cluster has weaker cores. It handles lighter processing, and in heavier processing, the cluster with stronger cores also helps the chipset. But the rumors about GS101 indicate that the CPU of this chip uses 3 clusters; A two-core cluster consisting of Cortex-A78, a cluster of two another core consisting of Cortex-A76 cores and finally a 4-core cluster consisting of Cortex-A55 architectures. That said, despite Whitechapel’s close relationship with Exynos, no Exynos chips with this architecture have yet been produced.
In flagship chips Snapdragon 888 and Exynos 2100 also has three clusters, with the difference that in both of them a single core cluster consisting of The powerful Cortex-X1 core is visible. In this way, despite having three clusters, the new GS101 chip does not reach Snapdragon 888 or Exynos 2100 in terms of processing power. According to some experts, in GS101 we will see performance at the level of a mid-range chip; Something like
Apparently, the GS101 chip has a graphics processing unit based on the Valhall architecture (ARM product). It should be noted that limited GPUs with Valhall architecture have been built so far, including Mali-G77 flagship GPUs and Mali-G78 and also mid-range GPU Mali -G68 pointed out. With this account, we will see a dramatic change in the accepted standard in the United States; Where phones built with Snapdragon chips – including Pixel phones – use Adreno GPUs (a Qualcomm product). Usually, the Adreno series performs better than the Mali series, but the benchmark scores obtained by comparing the Exynos and Snapdragon versions Galaxy S21 Ultra, indicating that the Adreno 660 GPU (on the Snapdragon 888) and the Mali-G78 (in Exynos 2100) have almost the same performance.
Security and artificial intelligence
Rumors about Whitechapel last year indicated that in the construction of the first chip of this project, the Pixel Visual Core and an NPU (neural processing unit) is used. If these rumors are true, the Pixel 6 – which will be powered by the GS101 – will see the return of the Pixel Neural Core integrated with the hardware (not as a separate chip).
According to some knowledgeable sources, the GS101 chip uses a new security chip called Dauntless. According to what we know of the Chromium source code, Dauntless is a chip that can work in devices equipped with Android and Chrome OS. Also, Dauntless is likely to replace the Titan-M chips in older Pixels, except that in the Pixel 6, the Dauntless chip will be integrated directly into the GS101.
The modem is a piece of hardware that connects the device to the operator. Without a 5G modem, your phone cannot connect to the 5G network. The modem can be a completely separate part from the smartphone chip. The best example in this field,
‘s attempt to make chips native, may be exaggerated and it is not unlikely to see headlines like this: “Google is ready to compete with Apple !”. But the truth of the matter is that, at least in the field of chipset and smartphone production, comparing Apple and Google is not correct. Apple is a 2 trillion dollar hardware company and the iPhone is its biggest product. While Google is primarily an advertising company and the hardware department of this company – which produces Pixel phones – is only a small and side project for Google.
It can be said that the most important benefit of the chip production by Google is the extension of the update period. When your smartphone has the support of its chipset manufacturer, it is much easier to receive Android updates. But after three years, Qualcomm abandons its chipsets and does not take any action to update the operating system of the devices. This lack of support from Qualcomm makes updating extremely difficult. If Google rids itself of Qualcomm chipsets, it could implement a 5-year Android update policy on Pixel phones (just like Apple has adopted for its iPhones).
Except for the category of updates, we cannot expect more from Whitechapel. It is interesting to know that many manufacturers of Android phones have tried to produce chipsets for their phones, although their success rate is different. Among these are Exynos Samsung chips and Kirin chipsets. Haisilicon product (subcategory Huawei) mentioned. Xiaomi in 2017 chip Surge S1 and recently saw the release of the Surge C1 camera chip in the new phone Mi Mix Fold Oppo is also developing its own chipsets.
Of course, none of these efforts have been as successful as Qualcomm, and most of the mentioned companies (except Huawei) prefer Qualcomm chipsets to their own chipsets in making their flagship phones. It’s interesting to know, all the chipset manufacturers – including Qualcomm – design their CPUs based on what ARM designed. Having said that, there should not be a significant difference between the CPUs of the same chipsets. Therefore, the main difference between the chipsets is related to the type of GPU and modem used in them. In these two areas, Qualcomm has performed better than others, and that is why most smartphone manufacturers prefer to use this company’s chipsets in the production of their products.
