AMD Ryzen 9 7945HX Analysis - Zen4 Dragon Range is faster and more efficient than Intel Raptor Lake-HX

[Redaktion]

AMD's new Zen4 CPUs have finally arrived and the new flagship Ryzen 9 7945HX competes with Intel's Raptor Lake HX models. The performance of the new Zen4 cores (Dragon Range) is very good and the Ryzen 9 is also more efficient than Intel's HX CPUs.

All this is nice but outside of benchmarks, in the actual usage, Intel will still be faster - and it will be available to get right from the start and not 9-15 months after the announcement.

There is no point in this review, because. people buying laptops with such solutions are guided by completely different criteria.

Secondly, 7x45 is a morally obsolete Zen4 with a poor built-in video card against the background of the latest Zen4 Phoenix, which has BETTER energy efficiency and a much better built-in video card. As well as support for 256GB of RAM, while the infamous 7945HX and all Intel only support 64GB of memory on 2 slots.

Everything will determine the price and capabilities of a particular laptop model and nothing more, in a particular country and place of sale.

What prevented AMD from releasing the 7945HX at "4nm" except that they could NOT physically release it on time? Another failure of AMD in mastering advanced technical processes, especially since "4nm" has long been obsolete - Apple is already working with "3nm" at TSMC.

As a result, whatever one may say - if the goal of a person is to get the most balanced solution - the entire x86 camp has been swallowing dust for a long time and was disgraced against the backdrop of Apple with ARM and M2 Max.

With just one memory controller, the M2 Max is officially 5(!) times faster than the best Intel/AMD solutions for laptops.

RIP x86.

Exactly, what on earth happened to Ryzen 6000 series, I waited months, was ready with my wallet but they where nowhere to be found. Every store has a real world choice between Intel 12th gen and Ryzen 5000, they're even offering Intel 13th gen or Ryzen 5000. AMD completely dropped the ball for mobile processors and it's left me feeling disillusioned with the brand.

I've been writing for 3 years now that AMD sells "paper" processors, which you really can't buy anywhere as part of ready-made and, most importantly, adequate solutions in terms of capabilities and price, at least within 1 year after the official release, in mass series. Now it has reached a complete disgrace - up to 1.5 years. Moreover, AMD themselves announced to the public in January that they were deliberately holding back the supply of scarce series in order to inflate prices. In theory, such a decision should be investigated by the antimonopoly authorities of all countries and AMD should receive fines for this.

AMD deliberately changed the labeling of the series in order to confuse ordinary illiterate inhabitants by creating a bunch of 7xxx series, of which only 7x40 and 7x45 are related to the new Zen4 cores. At the same time, the "top" 7x45 series is actually built on outdated cores with the "5/6" nm process technology, and not "4 nm" as in the case of the "paper" release of 7x40, which is still nowhere to be found in April 2023 on sale and will not be until the summer. And you can forget about the mass deliveries of the advanced 7x40 until the winter of 2024. Then what's the point of declaring all this and dishonoring it from the very beginning, Lisa?

On the planet, an oligopoly of Intel / AMD in x86. These patent trolls held onto patents for 30 years that should have been in the public domain 10 years ago.

All patents owned by TNCs must expire in 7 years, no later. And only startups should protect for a longer period. But once they get big, the rules also change.

Apple is clearly not the company that is ready to deal with x86, because they are making a totalitarian closed ecosystem for sectarians, not an open one. If they started selling the platform on M2 Pro/Max to everyone, as they did with x86, it would be a completely different scenario. Because there are no other applicants left with such a dominance of idiotic patent law. The entry price is so high that all startups will be automatically cut off.

Find it strange they are calling it the 'best laptop CPU' and they haven't tested gaming results where Intel clearly have an advantage. Bias much?

Dragon Range is 16 cores and high power, intended for bigger laptops with dGPUs. Phoenix is an 8-core at lower power intended for smaller and more mobile devices. 16 cores vs 8 cores - you are comparing apples to oranges.

Aside of some rare DTR cases, you will have at best 2 SODIMM slots, not 4 and in the majority of thin laptops with Phoenix the RAM will be soldered at 16GB. And a low-power 8-core CPU won't see realistic use of 256GB of RAM. Even the 16-core may have problems finding a valid use case to use more than 64GB of RAM while not having a RAID ultrafast storage or other solution for tasks usually found on high end desktop workstations with Threadripper or Epyc.

With just one memory controller, the M2 Max is officially 5(!) times faster than the best Intel/AMD solutions for laptops.

RIP x86.

Double or triple the price, one-year warranty, hostile to the right to repair, soldered RAM, soldered STORAGE, and one metric irrelevant on its own... yes, sure x86 is in a "poor" state :D

The other advantage of the Raptor Lake-HX chips is the lower idle consumption thanks to the efficiency cores.

Well, a crazy though but maybe, just maybe it's because it's monolithic? While the AMD one is chiplet? Those efficiency cores won't help versus monoolithic Rembrandt or Phoenix AMD Zen designs.

En segun

do lugar, 7x45 es un Zen4 moralmente obsoleto con una tarjeta de video incorporada deficiente en el contexto del último Zen4 Phoenix, que tiene una MEJOR eficiencia energética y una tarjeta de video incorporada mucho mejor. Además de soporte para 256 GB de RAM, mientras que el infame 7945HX y todos los Intel solo admiten 64 GB de memoria en 2 ranuras.

Man muss wirklich kein FANATIKER sein, um zu verstehen, dass Intel dieses Jahr 2023 mit seinem RaptorLake praktisch genauso viel verloren hat wie letztes Jahr und zu allem Übel mit einer Xe-Grafik, die sogar die alte Vega 8 übertrifft.
Jetzt verfügt der Zen 4 7045 über RDNA 2 und AMD ZEN 4 7040 Phoenix = DDR5 + RDNA 3 + USB 4.0 + HDMI 2.1 + KI Künstliche Intelligenz mit XDNA-Architektur, entwickelt von Xilinx, einem führenden Unternehmen für künstliche Intelligenz, und das alles bei 4 nm gegenüber 10 nm von Intel .
Zen 4-Chips haben einen geringeren Verbrauch und eine höhere Effizienz gezeigt. Intel muss bis 2024 warten, um das zu übertreffen, was AMD hat. + FSR 3.0 wird ein insgesamt flüssigeres Spielerlebnis ermöglichen, während Entwickler mehr GPU-Zeit für die visuelle Qualität aufwenden können. Latenzreduzierung ist ein wichtiger Schwerpunktbereich für FSR 3.0 – AMD hat den Gamer im Auge, mit hohen Bildraten und geringstmöglicher Latenz als Kernanforderungen. Ingenieure suchen auch nach einem reibungslosen Upgrade-Pfad für Titel, die derzeit FSR Version 2.0 verwenden.

You have porridge in your head and everything is mixed up. AMD has nothing but 7x45 on an outdated technical process, which really has pci-e 5.0, but there is nothing to do with them. This series has the most primitive built-in video card, only 64 (96) GB of memory.

7x40 has pci-e 4.0 (no matter how strange it is, everything should be the other way around with the 7x45 series), but the new technical process, so its version of Zen4 cores is much more energy efficient than the 7x45 cores. This series has the newest and most powerful integrated graphics, support 256(384)GB memory. 2 built-in USB40 ports and of course the AI block that AMD boasts so much about.

But the 7x40 series only exists on paper as of April 3...

7x40HS is ideal for business notebooks. But we won't really see mass models with them until winter 2024, when AMD will already promise us Zen4+ by March 2024...

It's futile to mention AMD anymore concerning their APU's in products the masses want. Like many have iterated here, it's all paper launch for AMD to get the investors excited for the time being then no release of said product for a year or more.

Take for instance Lenovo's Slim 6/7 and Yoga 6/7 (The only major manufacturer which uses AMD APu's the most). Last year's Yoga 7 14 with the 6800U took it's cool time to be released but then they forgot about the North American market - Fail. Everything thing else was Barcelo 5*25U series
Now this year Lenovo released all their "new" AMD variants with refreshed Barcelo 7*30U again!!!! (Remember, this is the mid to upper midranged category and not their slim/ideapad or below series).
They updated their PSRef site with future releases of the refreshed 7*35U series, while the intel Raptor lake variants are already on the market with some releasing later this month. Furthermore the very popular Slim 7 Pro series - the AMD variant, is only capped at 16GB of Soldered RAM!
One can forget about the high end categories as pc makers refuse to carry AMD at their flagship models like Dell XPS, Slim/Yoga 9 series, HP Spectre etc.

I give up looking for an AMD product of my needs. It seem AMD's target markets are Gaming, handhelds and mini-pc's as these were more available last year with the 6000U series.

AMD is dead. RIP
