"A new Kryo CPU that offers 20% faster performance than the Snapdragon 888 and which sucks up 30% less power. On the GPU side, Qualcomm says the Adreno processor will offer a 30% speed boost while being 25% more efficient than its predecessor. A solid upgrade all around, then, but not exactly needle shifting."
As a power user and someone who upgrades either annually or biannually I'd say that's one of the biggest Samsung upgrades yet tbh
