seulement 12% derrière mon Ryzen 7 3700x.

même niveau GPU c'est top !
he 4900HS is around 31% faster than the 3750H in this workload, which makes it faster than a low-end discrete GPU offering like Nvidia’s MX250. :

je pense que ces prix étaient déjà effectif,
mais c'est top !
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

très puissant mais pas mal d'appli ne scalent plus après 32 coeurs sous Windows :

intel en PLS
mieux que leur daube dual socket à 20 000$
4800H + 5600M graphics (8c+ 16 t seulement 799$ !) : edit peut être pas cette version .
Entry-level configurations presumably based on the Ryzen 5 4600H (six Zen 2 cores) with an integrated Radeon GPU (384 SPs) will cost $799, whereas other machines will naturally be more expensive.

(It’s worth noting that at a 7% annual improvement needs to be met, if a new product comes out every 18 months, then to stay on the same trend each product needs a +10.7% improvement.)
+ou - 10% en gain en IPC à chaque génération minimum prévue.
et une petite partie sur les capacités de TSMC :
Citation :
We did have some shortfalls on chips when we first launched our highest performing Ryzens, and that was simply demand outstripping what we had expected and what we had planned for.
That wasn’t a TSMC issue at all.
Tout va bien selon eux.
le 3970x écrase aussi le processeur Xeon (serveur) de 28 coeurs :
