5800H or 11800H

[MetalZero]

Hi,

I just bought a Lenovo Legion 5 Pro with an RTX 3070 and I'm pretty happy with it. I just saw Intel announced the 11800H and Legion 5i Pro. IDK when it will be available but should I return and wait for the 11800H?

Personally I don't care about gaming performance, they'll be so close that I'm not going to tell the difference without fps graphs. I care about raw processing power (programming/compiling code) and daily use.

There are some differences like AVX-512 and PCI lanes I think. What should I do?

Ryzen alsways has been better in raw processing power sso i would not worry about it. Also i would wait for Hardware unboxed to release their review of the 11800H to see if it is any better

TGL-H is about 5% faster in general, however efficiency doesn't improve from 10th gen

 

Personally would still pick Ryzen 5000 as efficiency is king in laptops, unless you need the features in TGL-H like AVX512

I don't need AVX-512 but idk what it will give me. Are there programs that require that?

Intel® Advanced Vector Extensions 512 (Intel® AVX-512) is a set of new instructions that can accelerate performance for workloads and usages such as scientific simulations, financial analytics, artificial intelligence (AI)/deep learning, 3D modeling and analysis, image and audio/video processing, cryptography and data compression.2

Which is just the marketing side of it, yes. Afaik there is no software that REQUIRES AVX-512 as that'd exclude 99.9% of CPUs on the market. 

 

In other words, it very likely won't be the killer feature to switch for. Not until after the laptop is replaced 5 or so years down the road.

Require? No, but you can compile some stuff to make use of it. As an example, you can easily add -mprefer-vector-width=512 to make use of it on gcc.
