The widely rumoured Samsung Exynos 9825 chipset has been announced ahead of the Galaxy Note10 later today.
Unlike the Snapdragon 855 refresh with the 855 Plus, the Exynos
9825 is a bit more than just a clock bump. The new Exynos 9825 SoC is now manufactured
on the Samsung 7nm LPP (EUV) fabrication process which should bring a range of
advantages.
The Exynos Galaxy S10 was criticised by many reviewers for its poor battery life compared to the SD855 variation, one reason for this is that the SD855 is made on 7nm silicon from TSMC vs the 8nm of Samsung’s. As well as the power disadvantages, this also means that the die area was physically larger on the Exynos at 127mm² versus the smaller 73mm² competition.
So, in theory, the Snapdragon 855/855+ and Exynos 9825
should now be level pegging in terms of power efficiency from the fabrication
process, though other factors will affect this.
On top of the improved fabrication process, Samsung has bumped
up their core clocks similar to the Qualcomm, at the moment it is unclear on
how the GPU is affected, but the two Cortex A75 cores have gone from 2.31 GHz
to 2.4 GHz which represents a 3.9% improvement.
In comparison the Snapdragon 855 Plus raised the clocks of the Prime CPU core by 120Mhz from 2.84GHz to up to 2.96GHz, giving a 4.2% boost. So it will be interesting to see how the increase in frequency across the middle, not top cores, will affect the Samsung performance.
On the GPU side, Samsung has also stuck with the same GPU
configuration as with 9820, using a MP12 configuration of the Mali G76.
According to the company, the 9825’s GPU is clocked higher – so it will
outperform its predecessor, however, the company has yet to disclose specific
clock speeds.
Qualcomm raised their GPU clocks by 87Mhz from 585MHz to
672MHz which represented a 15% improvement, so I wouldn’t be surprised to see a
similar increase here.
Previously there were rumours that the new Note10 would feature the Snapdragon 855 Plus but it now looks like this is not the case and the Exynos 9825 SoC will allow them to have performance parity or better than the SD855+.
