ROG Strix Scar 17 (2023): Compute Performance

Typically in previous notebook reviews, we lump basic compute and general performance in with our system performance summary. As we advance into 2023 and beyond, we'll split the sections up and use some of our 2023 CPU Suite benchmarks to measure performance, not just from a compute standpoint but also from memory and other compute-related variables that can substantially affect compute performance.

We'll also have more data points as we test more notebooks, and for now, we've included our data from some of our more recent yet relevant CPU reviews to judge performance. This includes AMD's Ryzen 9 7950X3D, the regular 7950X, and other lower-powered 65 W Ryzen 7000 CPUs. We've also added the Intel Core i9-13900K in for good measure, as, after all, the Ryzen 9 7945HX3D is technically designed to be a desktop replacement alternative.

(2-2) 3D Particle Movement v2.1 (Peak AVX)

Starting off with our 3DPM v2.1 benchmark, the Ryzen 9 7945HX3D performs insanely close to the Intel Core i9-13900K in the non-AVX section, which is very impressive, given that it pulls 1/3rd of the power than the desktop chip at full blast. Naturally, AMD's Zen 4 architecture includes support for AVX-512 workloads through two 256-bit channels, and as a result, performs very similarly to the 12C/24T Ryzen 9 7900 desktop chip.

(4-1d) Blender 3.3 Pabellon Barcelona: Compute

Next up is Blender 3.3, and in the case of the Ryzen 9 7945HX3D, it's more than capable of performing rendering tests. Sitting primarily between the Ryzen 9 7900 and the Ryzen 7 7700 (both desktop) processors, it outputs a lot of grunt for a 55-75 W processor packed into a notebook chassis.

(4-2c) Crysis CPU Render at 1080p Medium

In our Crysis CPU render benchmark, the Ryzen 9 7945HX3D performed very well and wasn't too far off its larger packaged desktop sibling, the Ryzen 9 7950X3D.

(4-5) C-Ray 1.1: 4K, 16 Rays Per Pixel

Looking at the results in our C-Ray 1.1 4K benchmark, the Ryzen 9 7945HX3D performs very well, even ousting the Ryzen 9 7900 slightly and making light work of the other sub-16 core chips on test; both desktop and the mobile Ryzen 9 7940HS.

(4-6) CineBench R23 Single Thread

(4-6b) CineBench R23 Multi-Thread

Often used as the go-to benchmark to measure CPU performance by users across the world, CineBench R23 yielded some interesting results. First of all, the Ryzen 9 7945HX3D was only around 8% slower than the desktop Ryzen 9 7950X3D, which also has the 3D V-Cache packaging. It also showed similar performance in the single-threaded test, which is understandable given both chips feature the same Vermeer Zen 4 cores.

(5-3) WinRAR 5.90 Test, 3477 files, 1.96 GB

Our last compute-related benchmark is WinRAR 5.90, which is sensitive to both CPU cores and memory. Again, we see very similar performance between the desktop Ryzen 9 7950X3D and the mobile Ryzen 9 7945HX3D, which is impressive. It's worth noting that the ASUS ROG Strix Scar 17 is using DDR5-4800 memory, which, if ASUS had used faster memory such as DDR5-5200 as per JEDEC specifications, the tables could have turned.

    any shots of the internals? I would hope this size of laptop supports more than 1 SSD.
  • Ryan Smith - Tuesday, August 22, 2023 - link

    Sorry, no shots of the internals. We were on a tight deadline here since Gavin had to catch a flight to Malaysia.

    We'll see about adding some once he's back.
  • meacupla - Tuesday, August 22, 2023 - link

    that's understandable. I look forward to them

    try the toms hardware review. it has pics of the internals. and it looks like it does support 2 m2 ssds
  • ballsystemlord - Tuesday, August 22, 2023 - link

    I also look forward to internal pictures.

    I'm curious if it's possible to overclock memory there to 6000? If i'm not wrong, then all actual memory chips are rated for less than 6000, so all 6000 modules are actually overclocked. So that should be possible to replicate? And that would the be sweet Zen 4 spot.

    Unfortunately, there are situations that this laptop can't deal with.

    Want good audio? It isn't on here cause it's using Realtek audio.

    Want good ethernet performance? It isn't on here cause it's using a Realtek LAN.

    The moment a laptop goes over $2000, they need to provide far better solutions for Ethernet and Audio as forcing somebody to pay even more money for external devices is a slap in the face.
  • meacupla - Tuesday, August 22, 2023 - link

    wait, you don't use a sound isolating headset with your laptop?

    Realtek ethernet is okay. It's about as reliable as Intel ethernet these days, which is to say they are both not reliable with drivers.

    The worst offender in there is the Mediatek Wifi. That thing is dogshit

    I got good experience with mtk 7922, it's a lot better than AX200 or 210 from intel.
  • ballsystemlord - Tuesday, August 22, 2023 - link

    Well, Intel Ethernet has had bugs for years with 2.5G, IIRC.
    Realtek audio isn't that bad, it's the junky implementations that make it sound really bad from what I've read over the years.
