This is on the same 7nm process as RDNA1 was, but with an over 50% (65% for the top-end 6900XT) performance/watt increases, so this absolutely isn't just about process (although having high yields is key to overall product success

I agree that there's a lot of misunderstanding on clocks - I've been on the other end - evaluation and validation of embedded boards, including V1000 Ryzen SoCs, but I think I'd disagree somewhat with the characterization of

> Those SoCs hit (and sustain) their top clocks, whatever those are for that specific SKU. This is actually completely wrong. Almost no laptops sustain their top (boost) clock on heavy workloads. Most usually only sustain max performance

Yeah, this seems to be an unfortunate recent trend in some gaming laptops, presumably in a bid to save some weight and/or cost, but luckily, it still seems rare enough that any time it happens, the manufacturers still get called out on

Hmm, I suppose it's fallen a bit out of favor recently, I don't see it quite as much as I used to, but it's pretty much standard terminology in the semi industry showing up in everything from academic papers to data sheets (c

I have to agree that the latest AMD Renoir processors are beasts - I have 4800H in a laptop that can sustain 54W TDP OOTB and CPU benchmarks are within spitting distance of my 3700X workstation. Amazing for a 1.5kg portable package. I'

Passmark and Geekbench are decent CPU benchmarks for general performance and indeed both show about a 2X multi-threaded difference: * https://www.cpubenchmark.net/compare/Intel-i7-1185G7-vs-Inte... * https:/&#x2F

The problem isn't hitting the top clocks, but sustaining them. Only the biggest "desktop replacement" class laptops tend to be able to sustain 120W+ CPU dissipation. Note that workstation-class (H) laptop CPUs also make compr

One of the things to keep in mind is that any one study is part of a larger picture and part of why I recommend people do their own searches so they can see what kind of studies are out there (or to start with reviews). For any individual s
