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.

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

(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.

(4-1b) Blender 3.3 Classroom: Compute

(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.

    Check Future's other website, Tom's Hardware Guide. They had more time to open and examine the interior of this laptop and from that you may be able to obtain answers.

    I do agree that even relatively modest computer hardware remains relevant and functional for quite a while. If you don't mind dealing with Linux, a Core 2 Duo laptop with Intel 4500MHD graphics is sufficient for everyday, mundane tasks. The graphics processor's lack of support for OpenGL 3.0 or newer will severely limit video games, but something like that can and does chug along in YouTube perfectly well and can help you pay bills, type incoherent nonsense in Discord, and crunch a spreadsheet or run a word processor.

    It doesn't take a genius to figure that out and decide to skip burning cash on any computer. Take games off the table and literally any piece of computing trash is perfectly acceptable and leave you with a fair bit of money to use for food/shelter/clothing/investing/etc. Not sure why people get so wrapped up and desperate to throw away 5% of their before taxes annual income on a toy to play games they'll end up being unhappy with in a year, but humans are idiots and easily exploited by other humans.

    getting from emotional towards rational/intellectual again, there are always several types of idiotic behavior/attitudes, further gradations/nuances and depending on perspective/aims a different outcome because of this behavior towards different recipients, its always a relative definition

    most of idiotic behavior, guessing, is motivated/originates from reduced/limited awareness/consciousness on surroundings/social&cultural peculiarities, misunderstandings with wrong premise, lacking experience/knowledge/education, naive trust into authorities/media/peer groups/leadership, lock-in phenomenon effects with emotions/customs/tradition/social&generation-based ties, diverse overextension, inadequate priorities, wrong time wrong place or (attempting a general summary) a limiting disorder/dysfunction.

    While rating of useless or unnecessary investments depend on perspective and relation between socially interacting participants, there's value to economical growth from this behavior, furthered through advertisements, public display of status and honor/credit or simply pleasure from (technical) progress.

    Famous and a 'never'(99%) outdated:
    ~1865 "One thing that humbles me deeply is to see that human genius has its limits while human stupidity does not."
    attribution to great astronomer within a book from an influential therapist ~1940s "Two things are infinite, the universe and human stupidity, and I am not yet completely sure about the universe.”
    maybe more original "Two things are infinite, as far as we know – the universe and human stupidity."

    for a conclusion, we, the people, are (too) imprecise (again and again, especially true and obvious with retrospective :) and this might be just an idiotic comment as well ;)

    Idling wattage seems being about 27W (with ~230W for gaming loads or ~310-240W with hardware stress testing).

    Greetings from Stehekin, WA, USA. Being a simple man on the street and a self-proclaimed Tech-Bro…I will never have a use for a laptop luxury! Constant fiddling with my ‘hobbled together’ Intel i5 Gen 4 desktop is however continuing in holding my interest and needs. All I can actually afford in this station of my life! I love your to the point descriptions as to…modest computer hardware remaining relevant for everyday mundane tasks, chugging along on YouTube and running my free word processor. Those indeed are my life and especially in the persisting challenging economic times like today! As to any serious gaming, these have largely been off the table for me as well, except perhaps for Castle Wolfenstein, Fallout 3 and still living with Mom to making it over the rounds. Someone here earlier spoke about “its always a relative definition”…my definition unfortunately remains fixed in my reality of today and it seems not to waiver even how hard I try in getting away from it!
