2x Cortex-A77
@ 2.2GHz
 
6x Cortex-A55
@ 1.8GHz

The new chip raises the CPU frequencies of its two Cortex-A76 cores 100MHz to up to 2.3GHz, seemingly retaining the same 1.8GHz clock on the six A55 cores.

Qualcomm is further raising the clock frequencies of its GPU and the new variant of the chip promises a +15 uptick in performance.


Today’s announcement also came with a partnership endorsement from POCO,

ualcomm’s new Wear 4100 SoC now finally abandons the Cortex-A7 cores and 28nm process

in favour of Cortex-A53 cores and a 12nm process

 – whilst certainly not bleeding edge, it’s a big jump in performance and power efficiency.

2x Kryo 560 (CA77) (même cœurs que sur le 865 mais il y en a 2 au lieu de 4)
@ 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)

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
