@ 2.0GHz
6x Kryo 560 (CA55)
@ 1.7GHz
Les premiers smartphones équipés du Snapdragon 690 devraient arriver dès le deuxième semestre de cette année avec un prix de départ démarrant aux alentours de 300 dollars
il va être possible d’imaginer des solutions mélangeant à la fois Cortex-X1 (x1), Cortex-A78 (x3) et Cortex-A55 (x4)

https://www.anandtech.com/show/15816/arm-announces-the-malig78-evolution-to-24-cores
Each of the 80 cores is designed to run at 3.0 GHz all-core
, and Ampere was consistent in its messaging in that the top SKU is designed to run at 3.0 GHz at all times, e
ven when both 128-bit SIMD units per core are being used (thus an unlimited turbo at 3.0 GHz)
. The CPU range will vary from 45W to 210W
Ampere has some performance numbers, which as always we take with a grain of salt.
These include 2.23x the performance on SPEC2017_int rate over a single 28-core Intel Xeon Platinum 8280,
and 1.04x over a single 64-core AMD EPYC 7742.
This is obviously extended into a number of claims about improved TCO. Ampere didn’t provide similar numbers for SPEC2017_fp,
because the company states that the SoC has been developed with INT workloads in mind
premiers autoradio avec du Soc Qualcomm !

Rockchip RK3588 featuring Cortex-A76 and Cortex-A55 cores, 8K video decoding support, 4K user interface support,
an NPU 2.0 (Neural Processing Unit)
RK3588
The processor should have eight cores in a 4+4 dynamIQ configuration
the new 8nm process is expected to increase performance by 20 to 30 percent, while the power consumption will be reduced by 40 percent.
Mass production is expected for Q1 2020.
Rockchip Video Encoder DecoderThe company also showed a slide with their video encoder/decoder IP, and Gen3 should be in RK3588 since that’s the only one with an 8K 60 fps decoder using either AVS3 or H.266 (VVC). I’m quite confused with the Gen1 decoder since it shows AV1 implementation too, and as such should be new as well.
An 8K 60 fps video encoder is also in the works.
H266 (je savais même pas que c'était déjà prévu)
" le codec HEVC H.266 est en préparation et sa normalisation est attendue pour octobre 2020."
