AMD Ryzen 9 7945HX3D Outed by ASUS ROG Laptop Specs

[T0@st]

Tipsters have noticed that ASUS is preparing a new high-end laptop with an unannounced AMD processor—the upcoming ROG Strix SCAR 17-inch model (G733PYV-LL046W,) will apparently sport a Ryzen 9 7945HX3D APU (with 128 MB of L3 cache). The inclusion of "X3D" in the processor's name has generated a lot of interest, given that Team Red's 3D V-Cache technology has existed mainly within mainstream desktop-oriented Ryzen 7000 and 5000 processor lineups. This leaked dual-CCD APU is probably being lined up to take on upper-echelon Intel Raptor Lake-HX processors, as well as refreshed variants.

The leak indicates that this APU will likely sit at the top of the Zen 4-based Dragon Range-H lineup—being a 5.4 GHz max. boost clock, 16-core/32-thread CPU, with a configurable TDP (between 55 W and 75 W) and Radeon 610M iGPU. The host ASUS ROG Strix SCAR 17 laptop is no slouch thanks to some very generous hardware specifications, including a mobile NVIDIA RTX 4090 GPU, 32 GB of DDR5 memory, 2 TB SSD, and a 17.3" 240 Hz IPS display. Listed at 5599 AUD (~$3800) on Computer Alliance, or £3904.79 (~$5000) chez Lamba-Tek, you would expect the best possible performance for those prices. The two online retailers have not confirmed any concrete release dates for the high-end ASUS laptop.

Ooh, so a baby 7950X3D with half of the L2 cache but more "L3" cache (on one CCX). I'm interested.

EDIT: Wait, no, this technically is a 7950X3D with a lower TDP (55W or maybe 65W) for laptops/desktop replacements.

It seems like a TDP limited 7950X3D so all cache capacities should be identical.

I mean, sounds interesting. I would be interested to see its performance in gaming as it could be really useful on the mobile space.

What a mouthful of a name. "Ryzen Nine Seventy-Nine Forty-Five 'haitch' 'ecks' Three-dee"
Otherwise, exciting.

I wish we'd see more gaming laptops with the 7845HX + 4090, that combo is very solid CPU with the top GPU and a slightly faster CPU isn't going to matter for most tasks anyway. Does anyone else feel like laptops these days are way over-specced on the CPU for the GPUs they're pairing?

Anyone but Asucks or Acer for the love of dog.

I doubt the choice of 7845HX would mean any meaningful price savings. It's also a 12 core, meaning a 6 core in games. Strange value proposition, strange choice to pair with a flagship mobile GPU.

In the past there have been strange nonsensical limitations on Curve Optimizer for non-flagship mobile Ryzens (e.g. no CO at all for most Cezanne, only Ryzen 9 Rembrandt have CO, and 7940HS lost iGPU CO). The two Dragon Range SKUs are fine, but there is still an argument to be made for sticking to top parts.
