Each time a brand new SoC arrives, we’re ready eagerly for somebody to launch a cube shot of the brand new chip. This course of is most attention-grabbing when the brand new chip comes with both a brand new micro-architecture or a brand new course of node. Final November, we reported on the discharge of Kirin 980's Shot from ChipRebel which debuted the brand new Cortex A76 CPU from Arm and the Mali G76 GPU on a brand new 7nm course of node.
The folks over there are again and seem to have been very busy in a single day, this time round demolishing the Galaxy S10 with the brand new Exynos 9820 . Within the final two initiatives, I've been going backwards and forwards with the ChipRebel staff, they usually're nice folks to go to once you want a shot.
The recording: Chip Insurgent – Annotations: Andrei @ AnandTech
eight nm not as small as 7 nm
The very first thing that stands out concerning the Exynos 9820 is the truth that the chip really grew at ~ 130 mm² in comparison with final 12 months's 10LPP-Exynos 9810. Samsung's 8LPP nodes are usually not as aggressive in scaling as TSMC's 7 nm course of, and theoretically the method node ought to have a conservative, 15% decreased space in comparison with its earlier node, so TSMC has a notable density benefit on this technology Has. In contrast with the Kirin 980 at 74.13 mm² the Snapdragon 855 at 73.27 mm² and even Apple's A12 at 83.27 mm² stands out the brand new Exynos 9820 considerably decrease compared to the competitors.
The Exynos 9820 additionally modifications quite a bit internally, in comparison with the Exynos 9810 final 12 months. To start with, we notice that the CPU cluster just isn’t as outstanding because it was final 12 months. The reason being merely that Samsung selected to make use of solely two of its new M4 cores, in distinction to the M3's quad-core format within the 9810.
The brand new cluster format is attention-grabbing for the cube shot: Along with the M4 cores we now see three L3 discs with an identical design as we’ve got seen within the 9810. Nevertheless, north of the 2 M4 cores we see one other L3 layer, which is totally different from the opposite three. It appears that evidently this disc connects the brand new Cortex A55 and A75 cores with the Samsung cluster.
I had the Galaxy S10 + with the Exynos 9820 in the home since yesterday, and I can verify that the L3 cache has stayed at a complete of four MB, although I would like a little bit extra time to determine how a lot of it really wanted That is accessible to the Cortex cores as vitality administration insurance policies come into play.
It is very important notice that the Cortex A55 cores are now not hindered as a result of they don’t use the identical higher-level cache hierarchy as the remainder of the CPU advanced.
The brand new Exynos M4 cores clock as much as 2.73 GHz, the A75 cores as much as 2.31 GHz and the A55 cores as much as 1.95 GHz.
On the GPU facet, we nonetheless see Samsung dedicate loads of house to the Mali G76MP12 – although it doesn’t look as massive as final 12 months's G72MP18.
Lastly, beneath the GPU, we discover the brand new NPU from Samsung. It is a dual-core design with as much as 933 MHz and gives as much as 1.9 TOPs with an accuracy of eight bits, though Samsung ought to rely 6.9 TOPs in quantized fashions. Samsung itself publishes the footprint of this block with 5.5 mm².
We thank the fellows from ChipRebel for sharing this shot with the general public for offering an ideal evaluation of Samsung's new chip! On our facet we now have the S10 + internally, and I’ll work on the detailed system and the SoC check.
