In light of AMD and nVidia giving us more of the same, with small forward increments in hardware design, its nice to see Intel experimenting with design. Though some designs didn't pan out so well, some appear to. This year looks like a bridge to better architectures in the future.

What exactly is AMD not giving you in laptops? They moved mainstream APUs to 12 cores, have 16 desktop cores with 3D V-Cache, and soon mega APUs.

Technically its a 16 core processor with 8 cores only with V-Cache so you'd still need to core park anyways. Also mega APUs are nice but that means they'll also run toasty.

As the SoC Tile remains unchanged, Arrow Lake-H's NPU is capable of dishing out just 13 TOPS of INT8 performance

Decidedly a pro, no "Copilot+" "AI" features like Recall to worry about.

The author failed to note the obvious problem of looking at random scores in a benchmark DB, which is that you don't know what chassis they were tested in, or other parameters of the test. This is especially true for laptops, since Intel gives the OEM more control over power & boost, basically to match the system's thermal solution.

To be a true apples-to-apples test, you'd want to see these two CPUs tested in the same chassis, from the same vendor, with the same settings.

mega APUs are nice but that means they'll also run toasty.

Strix Halo (Ryzen AI Max) is specified for laptops with a TDP of anywhere from 45W to 120W. So, they're not small, but they also don't clock as high as the Fire Range ones (i.e. the ones to come in a X3D option), which will be paired with a dGPU.

Ryzen AI Max is clearly aimed at the upper-middle of the market, not the high-end.

In some form factors they're going to be replacing both a high-TDP CPU and dGPU, which could easily exceed the 120W cTDP. I think 60-120 Watts is typical for one of these laptop dGPUs (low end ones like 3050/4050 might be configured to use 35W).

Fair enough. Let's just hope the encoders are up to snuff for those that use their encoders

It depends on what you are using the laptop for anyway. I think its been proven that games don't require more than 8 cores, and non game software don't really benefit from the 3D V-cache. So if you game, the extra cache on the 8 cores is sufficient, while you still get to enjoy the benefits of the 16 cores when you need it to run multi-threaded software/ workflows.

As to running toasty, I agree. But this is generally a problem with any mobile CPUs due to the lack of cooling. To try and mitigate this issue, mobile CPUs operate with lower power limit and aggressive throttling. Hence, don't expect it to run as fast as the desktop counterpart, though you gain mobility in a laptop form factor. So it is down to individual requirements.

Not quite, but true to a large extent. Most PC productivity stuff has either too small or too large of a working set to gain more from a larger L3 than the X3D models traditionally have sacrificed in clock frequency. Phoronix has tested 3 generations of Ryzen and EPYC with 3D VCache and found some wins in certain compute tasks. Here are the benchmarks for the 9800X3D:

The TL;DR is that the following sorts of workloads sometimes gain a substantial benefit:

• AI (CPU layers)
• Some compression/decompression
• AV1 encoding
• Some server apps & database workloads
• Some HPC & simulation

Sadly, it doesn't really seem to benefit rendering or compilation. However, in the Ryzen 9000 series, there's very little downside to the 3D cache (other than cost). So, you can either buy it if you're the type who always wants the best at any price or if you know one of your common workloads stands to gain from it.

Some laptops have bigger, heavier thermal solutions and fans that spin way up. I don't want that sort of thing, in my laptop. As you say, I'd rather have a laptop that throttles more aggressively, in multicore workloads.
