Tasting a new generation of 7 Nm - an innovative production technique

The Exynos 9825 chip that runs on the Note 10 offers features that are almost completely identical to those of the God- 9820 we already knew at the beginning of the year - but it is based on new and absolutely promising production technology that will take over the field in the coming years

We did not expect significant news from models Galaxy Note 10 and Galaxy Note 10 Plus As far as their processing power is concerned, because we have traditionally seen these smartphones use very similar or identical chips to the Galaxy S models of the same year launched a few months earlier - but the current incarnation from home May be a little different, and bring with it a line that will become especially significant down the road.

The day before the announcement The Note 10 models themselves We got a much more modest official announcement for The Exynos 9825 Fresh - which is the first commercial product based on the manufacturing process 7 nm, 7LPP, which includes initial use of the The promising and intriguing Ultra Violet.

New-old - with very interesting production lithography

The Exynos 9825 paper is almost completely identical to the Exynos 9820 chip which starred on the various Galaxy S10 models starting March this year, with two advanced M4 advanced processing cores under dedicated development. Itself reaching 2.73GHz frequency (unchanged), another pair of powerful Cortex A75 cores up to 2.4GHz frequency (tiny increase vs. 2.31GHz frequency at 9820) and four cortex A55 cores at a frequency of 1.95GHz (unchanged) - all of these plus a Mali-G76MP12 graphical core that has not undergone any change either.

Preliminary results of tests Show minor improvement for the Note 10 models compared to the S10 models - but the full picture will only be received upon arrival of the full reviews

The graphics core operated at frequencies up to 708MHz on the chipsets 9820, and although we still do not know the maximum working frequency in 9825 can be estimated with caution that there will be no formidable leap here but a moderate (if any) addition that will improve the capabilities by a single percentage, similar to the power ratio in the general processing cores. So why is the note chip of the Note 10 and Note 10 Plus important and unique anyway?

Not afraid to highlight the use of EUV technology in advertising material to the general public as well, not necessarily aware of the full meaning of the matter - shortly before TSMC can make its own statements as part of the chips that will power next-generation devices And from Huawei

Created the Exynos 9820 In its 8 nm manufacturing process, first introduced as the second generation 10 nm production but finally renamed as a sort of chipmaker's marketing war designed to highlight the endless sense of technological development in the field - and the Exynos 9825 is the first commercial chip to be created In the second generation of the domestic production process 7 nm (the first generation has not ripened for commercial use so far, and may never ripen for it) which makes its first use of innovative 13.5 nm light sources during part of the manufacturing process.

The move from 10 nm production (and also 8 nm) to 7 nm production with EUV use should provide very large theoretical upgrades - but we're not sure we will feel them already in the chipset. Current 9825

Modern chip manufacturing processes include, among other things, the use of tiny, special masks on a silicon substrate and the activation of a light source to create the required material changes to function as miniature transistors - and so far the most recent and widely used source of 193 nm (Deep Ultra Violet - DUV) light required More and more "tricks" are used to allow the creation of elements of only a few dozen nanometers on the silicon substrate in question.

Switching to only 13.5 nm wavelength advanced light source can significantly simplify and accelerate the modern and future production processes in the market, as well as deliver significantly higher accuracy to deliver better performance with low leakage currents.

Any use of the technologyEven partially, should bring with it a significant improvement to the complicated, challenging and delicate manufacturing processes of the processing chips

Samsung is the first in the market to successfully integrate EUV technology into a commercial chipset line, and despite the fact that the product itself is not entirely new but has actually undergone a "conversion" from a previous manufacturing process, it is an important development that comes after many years of rejection - early estimates predicted us beyond using EUV More in production processes in And at 10 nm, which did not happen at last due to the fact that the capability was simply not ripe for proper mass operation.

Both TSMC and Fortunes are about to be used (first and foremost) in technology In their manufacturing processes at 7 nm onwards

It will be interesting to find out, very soon, the possible improvements that the Exynos 9825, and the Note 10 in general, have undergone - but even if we do not make far-reaching changes it is worth noting the importance of experimenting and scrubbing And other technology makers, before learning how to use all of its capabilities and benefits and begin transferring them to consumers and users as well.
