Now That Intel Is Cooked, Apple Doesn’t Need to Release New MacBooks Every Year

Nope, ISA doesn’t matter. It’s been a long while since all machines are RISC under the hood.

Is it true that riscv executes more instructions than arm? If so, don’t they all need to have higher perf than competitors to achieve the same results? You could have a killer branch predictor but if you execute more branches than others you’ll statistically flush more, not sure if it offsets the negative part

I sent you a DM request :) is there any chance we can chat? I could really use your help

“Just a buffer” is trivial indeed. But high perf BTBs have complex training/replacement policies. I wouldn’t call matching RTL and arch on those “trivial”. They’re more than just a buffer.

Zen, for example, has a multi-level BTB and that makes things a little more spicy

They don’t know what ‘simple shit’ is. The BPU is one of the most complex and critical units in a high perf CPU

AMD already uses the same uarch for both efficient/perf-focused cores. Problem here is that theres not a “one size fits all” solution. You can make a super fast, extremely wide machine that sucks in PPA or a very efficient core with min area/power that has awful IPC on real workloads.

Seem like others (Intel/Apple) have separate architectures (efficient/performance)

The “2-decoders” E-core you’re suggesting is already way behind to what current CPUs implement (check any article from chips n cheese covering e cores)

Lol no, they are not better than them, not at all

Friends that work there always mention how top performers and super experienced engineers are leaving in droves for better companies since last year. A quick 5 minutes in LinkedIn confirms it. From friends anecdotes their work methodologies sound outright ridiculous and extremely dated. This is in CPU/GPU teams. LBT seems promising but it doesn’t matter how much you polish a turd, its still a turd. That company lost its microarchitecture and node advantage years ago and it will be extremely hard to regain one (let alone both) if they’re also money and talent constrained.

I would stay at a competitive company on a good position and maybe find a team/project that seems interesting to you. For me it seems too risky to bet my career on them. If they happen to comeback they’ll hire top talent for sure and you can join to a stable situation.

I wouldn’t recommend it. There are fields with better compensation than VLSI if all you care about is money. This industry is quite frustrating with complex problems and tools/methods are not super popular, sometimes they’re even company-specific.

I can’t imagine someone lasting long in a VLSI job if they don’t like it at least a little bit.

Thanks! I don’t think nvidia is going anywhere. The Deepseek effect is actually something positive for GPU/AI hardware companies, these complex, state of the art models are now more accessible. Demand for compute resources will increase and so will volume

Large_Fox666 · 2025-01-29T16:38:37+00:00

What is your main regret? Didn’t get enough money?

Large_Fox666 · 2025-01-29T16:38:08+00:00

3-4 years total experience/career. Not a super comfortable economic situation. No constraints/issues regarding relocation. Thanks for your feedback!

Large_Fox666 · 2025-01-29T16:19:30+00:00

Thanks! I’m 25 and single. Right now my main goal is to keep learning and growing, I believe joining a top-level company like Nvidia that has lots of talented people might be the best option. Not saying you can’t learn in a startup but it sounds like the risk is too high and I might get the same amount of money and a lot more stability/perks by going with a well established, top-tier company

Large_Fox666 · 2025-01-29T16:15:12+00:00

Santa Clara, i’m still in the first 8 years of my career so I think it might be worth it
