AMD Ryzen 9 9955HX3D Laptop CPU With 3D V-Cache Tops Performance Charts in Early Benchmarks

[Cpt.Jank]

The AMD Ryzen 9 9955HX3D is an upcoming laptop CPU with 64 MB of L3 3D V-Cache paired with 16 Zen 5 cores that clock at up to a claimed 5.4 GHz. While the 995HX3D hasn't even received an official retail launch date aside from "H1 2025," tech publication Hot Hardware has published some early benchmarks of the new Ryzen 9 CPU, showing off some impressive performance chops that should translate to excellent gaming performance. The test system in question was the MSI Raider A18HX, which pairs the AMD Ryzen 9 9955HX3D with up to 64 GB of RAM and an NVIDIA GeForce RTX 5080 or 5090. According to CPU-Z screenshots taken by Hot Hardware, the 9955HX3D is configured to run at 55 W, although the CPU is capable of up to 75 W TDP. Hot Hardware noted that the 9955HX3D clocked up to 5194.88 MHz on two cores, while one core sat at 5139,98 MHz, and the rest of the cores all sat well below the 2 GHz mark when not loaded.

While Hot Hardware was unable to run direct gaming benchmarks due to release embargoes, the publication did run Cinebench, PCMark 10, and Geekbench, including Geekbench AI. While performance across the board was impressive, with the 9955HX3D scoring a massive 2094 in Cinebench 2024 multicore, which is 20% higher than the next CPU on Hot Hardware's benchmark charts, the AMD Ryzen 9 7945HX from the ASUS ROG Strix Scar 17. Geekbench 6 and UL PCMark 10 tell a somewhat different story, though, with the 9955HX3D scoring slightly behind the AMD Ryzen AI Max+ 395 in both benchmarks. Geekbench 6 was particularly peculiar, since the Ryzen AI Max+ 395 outperformed the 9955HX3D by as much as 48%. The 9955HX3D still beats out all the other chips on the Geekbench 6 test, though, especially in multicore testing, where the next-fastest chip on the chart was the Apple M3 Max. Despite the mixed results when it comes to multicore benchmarks, though, the AMD Ryzen 9 9955HX3D managed to come out on top in every test where single-core performance was directly tested.


In Cinebench 2024, the 9955HX3D scored an impressive 129 points in the single-core score, which is only outdone by Apple's M3 Max SoC in the MacBook Pro 16. In Geekbench 6, the 9955HX3D scored 3165 points, which just barely makes it faster than the trailing Apple M3 Max, which scores 3161 points in the same test. The solid mix of high single- and multi-core performance suggests that the AMD Ryzen 9 9955HX3D will be a fast gaming CPU when it eventually hits shelves in gaming notebooks later this year. Things also look promising when it comes to regular productivity workflows, which is an area where X3D CPUs previously suffered due to lower core clocks compared to their non-X3D counterparts.

A CPU like above will break open this market, and AMD's start to hit the shelters sooner or later. Word is out that these CPU's kick Intel's ass.

AMD CPUs have been kicking Intel’s ass for the last 5 years… yet here we are. They’re still trailing.

Despite offering superior products—at times vastly superior—AMD has struggled to gain market share from Intel in the laptop segment more than in any other. This is particularly problematic, as the laptop market is twice the size of the desktop market. I suspect Intel maintains a highly questionable and conveniently relationship with OEMs... On the upside for AMD, the increasing complexity and scale of 3D packaging, along with the reliance on more expensive third-party fabs, limit Intel's ability to leverage volume advantages or offer massive discounts.

Strix Halo is much more interesting to be honest

Dragon range was supposed to do exactly the same yet it didn't, so was Rembrandt before... and it didn't. And who doesn't remember Cezanne? Probably not many because it also didn't achieve much of a market share. Or Renoir... shall I go on?

Vastly superior? In what universe? The last time AMD was superior was over 20 years ago, before core 2 put AMD's balls in the vice and clamped down HARD.

The first mobile Ryzen generation was a huge backfire as AMD attempted to shift driver responsibility to OEMs and ended up pissing them off. The 5000s were competitive but I'd argue the 7000s were the first gen that was vastly superior since the days of Athlon 64. Even then, lunar lake is producing ARM like power usage figures and Arrowlake isn't worthless in mobile (or desktop, frankly). AMD still has some work to gain mobile dominance like they have on desktop, they have iGPU performance locked down though.

 

[tpa-pr]

I believe part of AMD's problem is chip supply isn't it? It doesn't matter if they make superior mobile chips if none of the OEMs can buy them

Not this completely unproven theory again.

It makes no sense, if supply was the issue we wouldn't just see a lack of AMD designs. There'd be shortages of existing AMD laptop SKUs. Yet we don't see that.

It kind of ignores how chip allocation is done in the industry. TSMC builds out capacity to meet wafer allocation contracts. If AMD wants more supply, all it needs to do is agree to buy more a few years in advance. AMD has had plenty of time to do so at this point. TSMC only dynamically allocates the extra supply it has beyond any contractually obligated capacity to each of it's customers. Companies like AMD can dip into this extra supply if it needs to and is able to outbid other companies but it will always get the amount of wafers it signed for on it's wafer supply agreement.

Have a 7945HX X3D board coming soon. Will be interesting to see how they compare at the same power.

Perhaps a company should launch a Laptop like the Dell XPS Gen 1/Inspiron 9100 (it was thick and heavy but never throttled under gaming, or overheated) and not notebook. This would be the Ideal CPU for it, then pack in a High End Mobility Radeon for it.

 

[mkppo]

For DTR gaming laptops the 7945HX3D has been vastly superior to pretty much any other CPU since it's launch tbh. Consumes less power, matches 13980HX in MT performance while comfortably beating it in gaming benchmarks while consuming less power (and vastly better scaling at lower power levels)

Having the CPU consume less power is useful in thermally constrained systems as you can pump more power into the GPU if needed.

9000 series will widen the gap but yeah, don't expect too many design wins but certainly more than the 7945HX3D's.

 

[Tek-Check]

Long are gone the times when Intel had 90% of share in anything. Check the numbers. Getting worse for them every year. Plus, there's Apple in laptops too.

Semiconductor sector for client market is not as bakery. Changes are gradual and slow.

All of those AMD generations achieve gradual gains as laptop sector moves slowly. Even super rich Apple had to work very hard to get a few percentages since they divorced from Intel. Patience. This market changes slowly. Patience. Ask the same question in 2030 and you will see more changes. If you ask this question a few times a year, you will not see bigger movements.

Companies like AMD can dip into this extra supply if it needs to and is able to outbid other companies but it will always get the amount of wafers it signed for on it's wafer supply agreement.

They have been bidding for gradually higher amount of silicon and that's exactly reflected in their gradually increased market share over the years.

The 7945hx3d is actually atrociously bad for a gaming laptop. Monolithic amd chips are much better suited for that cause they actually need 1/3rd the power to play games, leaving a lot more room for the GPU. You are not CPU limited most of the times in a laptop since their GPUs are nowhere near as fast as the desktop ones. Also multi ccd chip draws a crapton of power even for just browsing, making it a bad experience if you are not plugged in with your laptop.

Just the first test I came across

The 7940hs has 250% the battery life of the 7945hx3d while the latter has a 40% bigger battery.

And another, hx3d is literally at the bottom

Not only matches in MT, but comfortably beats it.

How do you use this laptop during gaming? I hope you don't wait roughly one hour until battery is discharged and then plug it in

I don't use it unplugged for gaming, I use it for work, browsing, excel etc and yeah, on battery on my couch, on the beach, on my vacations. I don't go around plugging it in random places...if the plan is to always have it plugged in, i wouldn't get a laptop.

Not sure what point are you trying to make. Everybody knows that halo machines have rather poor battery life, but that's not part of their appeal to some crowds who enjoy those devices.

Sure, for work and browsing you get another two hours or so, and that's about it. There's nothing mysterious about relatively poor battery life in those machines with halo CPUs.

Im explaining why you don't and won't see it being used in a lot of designs. It's not because intel is bribing whatever and whoever, it's because this CPU does not make for a great laptop. It's for very specific cases where you need a portable desktop with a monitor attached.

There will always be limited amount of halo designs, a few for gaming and a few for workstation. It's a super niche segment anyway. Nothing new.

I think you forgot that Intel's offering in the mobile market with the U series was limited to dual-cores with HT. When AMD entered the scene, it wasn’t revolutionary, but it introduced a competitive product, only held back by the GlobalFoundries inferior 14nm process. There were also some driver issues, sure, but by the 3xxx series (Zen+), AMD had the superior and more affordable option, with stable drivers. Even Vega 3, the lowest-end AMD iGPU, outperformed Intel’s integrated graphics in Whiskey Lake most of the time.

With the transition to 7nm in the 4xxx series, AMD pulled far ahead, delivering octa-core CPUs with iGPU and greater efficiency than its competition, which was stuck with the mediocre 4-core Ice Lake. Intel only managed to compete on equal footing again with Lunar Lake (3nm), but this platform is too complex and expensive to be truly competitive, and software issues remain a concern.

You're comparing apples to oranges. Not sure why. My post is entirely factually accurate. Essentially it matches it's intel counterpart while consuming near about half the power and destroys it in gaming. I was just wording it more politely lol

No, your post isn't entirely factually accurate, far from it. Just looking at the post you just linked, your efficiency claims go literally against the link you just posted. The intel part is both faster and more efficient than the 7945hx 3d in the ST test suite. In the MT test the 13980hx is faster than the 3d but they don't have the intel part at all in the efficiency chart, they only have the 13950hx for whatever reason. But I highly doubt that the x3d is consuming half the power, since the 3d is at 160 watts, you are now claiming that the intel laptop would be drawing 320 watts....ayokay bud.

 

[evernessince]

They have been bidding for gradually higher amount of silicon and that's exactly reflected in their gradually increased market share over the years.

Only extra production over what they are contractually obligated is bid on. In addition, the date we have contradicts a gradual increase: https://www.macrotrends.net/stocks/charts/AMD/amd/revenue

Given that AMD primarily sells chips, those charts and your statements cannot both be correct. You cannot see those large increases in revenue without AMD also securing large increases in supply.

And again, looks at the instances in which you see AMD product unavailability. You see it with the 9000 series where AMD is outselling last gen by 10x and in the 9800X3D that alone outsells Intel's entire lineup. You aren't seeing it in laptops.

AMD doesn't have unlimited supply sure but I see no evidence that supports the other guy's claim that AMD doesn't have the throughput to increase it's marketshare in the lapotop space at a more rapid pace. There is definitely an element of the old boys club going on between the OEM and Intel.

You would not buy a 7945HX3D laptop and use all those cores without plugging it in. It's designed to be a mobile workstation, you go to your hotel and plug it in while it runs encodes or while you work on it.

If you want power efficiency, you'd get the 12 core AI MAX from AMD, although you are still going to want to plug it in for heavy work. There isn't a high-end laptop out there that will last long when maxing it out.

7945HX3D uses 30w at idle but it's also the highest performing mobile CPU on the market and also the most efficient when fully loaded. You are paying to have a tiny portable desktop.
