lol... now who's putting words in people' mouths... I'm simply stating that PRICE is key - read my first posts... if this is priced as a top tier CPU (ie: same as the 12700 or 12900), then it is a terrible choice, as those wipe the floor with it.

If it is cheaper, then depending on how much cheaper, it is a good purchase... but those thinking to get top-tier performance will be sadly disappointed - as this review was quite clear on showing with it's plentiful graphs :)
"Anyone paying for that CPU and using the iGPU is a fool"

Regardless of price, what good is a dGPU if the buyer has no use for it?

Also, You can daily drive a 6900. Not so much with a Ferrari.

Those power numbers are really impressive. The most interesting part though is how close AMD is getting to the M1 pro. Apple's magic ARM chip, as it turns out, may just be benefiting from being on 5nm (many of us alread knew this) and I cant wait to see what zen 4 on 5nm brings to the table.

Based on the graphs, maybe? Zen 3+ is dramatically more efficient then zen 3 was, and zen 4 will be on the notably more efficient still 5nm node. In the majority of cases for laptops zen 3+ will be superior simply because most laptops cannot entertain 45 watt power draw today, let alone 75 watt.


Getting a i5 or ryzen 5 means getting a slower and weaker iGPU. Did you not think that someone buying this for the iGPU might, well, want the iGPU?

Shocking, I know, but not all of us want a big hot dGPU in a big, heavy laptop when all we really need is a better iGPU for casual gaming. My 4800h laptop has no dGPU and works great for most games I play on the go, like tropico or civ, and has the added benefit of working out of the box with linux, unlike dGPU setups. If you are using the iGPU, the higher TDP of the H series chips allows for higher/consistent GPU boosting. The 4800h and4700u are the same chip, but the 4700u only maintains 1200-1300 mhz GPU clocks while the H manages 1600 mhz consistently, the real life result is the H is anywhere from 20-45% faster depending on the title. And when you are not gaming, the H is a stone's throw away from the U in terms of real world battery life.

Granted, I think it would be nice if AMD would make a ryzen 5 with the big iGPU for people like me, but they dont make one, so we have no other choice. A ryzen 5 with the 680m and LPDDR5 RAM would be very interesting indeed.

Even if you are OK with a thicker laptop (I myself miss the days of 0.9-1.0 inch thick laptops with good cooling systems like the dell e6440 or lenovo l440) cooling 75 watts of intel CPU is a loud and difficult affair. That's just too much for a laptop's cooling system, especially if paired with a dGPU.
well the e6440 had like 1 heatpipe. thermal density is a thing. compared to now where laptops use vapor chamber or something around that.

If you have no use for a dGPU... then buy a 6500... or 3600... or any other laptop... why spend a premium for the 6900?

There is a VERY SMALL niche of users who will require CPU intensive tasks of the 6900 yet requiring such a small power envelope that a dGPU or Alder Lake CPU would require...

Those who are power users should be getting the 12700 (or 12900 if they must have the absolute best) and pairing it with a dGPU...

Those who simply want "everyday work" should be getting a cheaper CPU/iGPU combo...

If the 6900 with iGPU outperforms a 12500/nvidia 3050.... and is priced comparably.... then we're talking...

But what if you need the power of the 6900?
And I thought your argument was about price of the 6900?

Or are you just trying to say AMD doesn't know how to configure and sell laptops? Or are you saying techspot is wasting their time and ours reviewing this configuration of laptop?

Did you READ my post? I'm guessing not...read my second paragraph....hint: look for "power envelope".

AMD is banking on users assuming that the 6900 is the top mobile CPU... and had Alder Lake not been released, it would have been true. Just a few months ago, I assumed that the best laptops to purchase this spring would be AMD CPU+Nvidia GPU and was bemoaning the lack of options last year in that regard (you can probably find a few of my posts about it!).

Alder Lake changed the game... now, the best laptop money can buy will NOT be a 6900/3080Ti... but a 12900/3080Ti!

With the "high end" no longer a reason to purchase this CPU, there are very few reasons left... it's not that it is a bad CPU... it's just that you have better options now.

If AMD makes the price lower... then you have a reason to buy it again...

Oh it's about power envelope now!
12900K has an iGPU. I guarantee you it's not there just in case something is wrong with a dGPU. I guarantee it's not niche.

Do you get it now?

It's there for the same reason the 6900 has one... in an attempt to gain a few more sales... but you'd be just as much of a fool to purchase a 12900 without a dGPU as you would purchasing the 6900... doesn't mean people won't do it...

Nope. You don't get it.
I think we're done here.

People who think that Apples efficiency comes only from a process advantage and not the fact that ARM uses far less power to run are extremely delusional. Apples M1 doesn’t consume as much power at max load than these Ryzen or Intel parts. In fact it consumes 39w at the wall at max. Which is less than these Ryzen parts when boosting yet still faster. But the main difference as shown in the graph here is at idle the Ryzen part is using 28w and the M1 is using 7watts. That’s going to make the difference on your battery.

https://www.extremetech.com/extreme...maxs-power-efficiency-should-rattle-intel-amd

Anyone who thinks that shrinking from 6nm to 5nm will make your idle power consumption drop from 28w to 7w is in for a big disappointment. If you are one of these people then please go learn and understand the differences between ARM computing and X86 computing because you obviously don’t understand them currently.

There is a reason why both Google and MS are scrambling to get their own ARM designs out.

6nm vs 5nm node difference from TSMC is Huge.

The 6nm Node is only slightly better than their 7m Node.


The M1 is also highly integrated so there is a lot less on the motherboard that needs power.

M1 is scaled up Phone Tech, Intel and AMD's Mobile chips are scaled down Server Tech. Clearly they are not going to compete 1:1.

Until we see a Mobile X86-64 Chip with the integration that the M1 has, we are not going to get idle level power consumption that ARM does.

At the same time we are far off from seeing a ARM core that can compete anywhere near what Powerful X86-64 Cores can do at high clock speeds.

When regarding some of Apple's M1's most impressive tasks, like video encoding. It is heavily speed up by the built in encoders. The future M1 type chip coming out for the Mac Pro will largely be a multi threaded beats than single threaded, most likely 2-4 M1 Max/Pro chips on a single board. It will be good for workloads that scale.

We won't be seeing 5ghz Arm chips in the next few years that is for sure.

Techspot, you forgot to mention, that Ryzen 6000 series is all about perfomance per watt and power savings when system is not on 100% load.

And I don't like fake Intel laptop systems, which if honestly, are desktop systems with integrated batteries, because of their huge power wasting.

The series yes.... but the 6900 is also meant to be the best mobile CPU you can buy... had Alder Lake not come out, it WOULD have been.... but since it ISN'T, Techspot is right to call it out...

We'll see if AMD compensates by lowering the price...

Agree but Zen 3+ also has a regression on power usage. This HS version has higher peak power usage for both single-thread and multi-thread just not as bad as Intel pushing back Pentium 4 principles on a laptop which is ridiculous.

A test of these system on battery power is much needed as contrary to exotic vamper chamber, battery technology cannot keep up to this crank up of power usage.

"Today we’re checking out the Ryzen 9 6900HS, an HS series chip targeting a 35W TDP for performance-oriented ultraportable systems, as opposed to the regular 45W TDP for the rest of the line-up. Aside from this TDP difference, the 6900HS is essentially the same as the 6900HX on the spec sheet: 8 CPU cores with 16 threads, base clock speeds of 3.3 GHz and boost up to 4.9 GHz, 16 MB of L3 cache plus 4MB of L2, and a new 12 compute unit RDNA2 integrated GPU clocked up to 2.4 GHz. All of this has been fabricated on TSMC’s N6 node."

It's not as bad as you seem to think because the HX must be faster. At any rate, my R5-3500U is more than fast enough for my mobile tasks. :laughing:

The HX isn’t much faster... I don’t think AMD expected Intel to catch up this quickly.... will see how Zen 4 does next refresh...

Did I miss the battery life tests? These results are quite at odds IIRC with Linus Tech Tips. The Intel was only really faster above 70W and was SLOWER between 25-60W and had much worse battery life.

Look for nearly all these tests other than compiling and one or two others no one would even notice. For a portable device with plenty of power and plenty of battery life the AMD would be my pick any day. Still I'm eagerly awaiting Phoenix APUs. but Raptor Lake hopefully sees a big boost to reducing power usage.

Will we see ARM chips that can even outperform the A14/15 let alone M1 class chips. If Qualcomm's 8 CX Gen 3 can't be right up their with Apple's phone class APU they are in for a long hard road. They don't have the resources to aim higher at the M1 class IMO.

It all comes down to pricing... can I get a 12700 for the same price as the 6900? If so... epic fail for AMD... if the AMD laptop comes in 10-20% cheaper.... then we have a product...

Anyone wanting the "best laptop" will be going Intel this round... but you don't sell too many of those.
Same or lower price is very possible but G14 form factor can't accommodate 12700h heat

Qualcomm makes 8cx to put 5g in laptops.
8cx gen 3 uses older arm x1 instead of newer x2 found in smartphone 8 gen 1

AMD never mentioned, that 6900HX will be most powerful mobile CPU. But on the other hand, AMD presented, that Ryzen series 6000 will come as best performance per watt product, when compared to mobile Intel CPU solutions.

They didn’t mention it in public… but they almost certainly believed it when they designed it… and again - they would have been right… had Intel not made Alder Lake…

The iGPU performance is NOT irrelevant for an HS series part. These are laptops after all, and they're going to be run on battery power some of the time. In that scenario users are likely to turn off the discrete GPU to conserve power; AMD's superior iGPU will shine in that use case, providing much better performance than an unplugged Alder Lake system.

Quite a biased article. Whenever the 12700 was in danger of being CREAMED by the 6900HS iGPU, they added an dGPU so that Intel could pretend to run better. This article is built from 100% total Bias. UNSUBSCRIBE.

Intel has created a new class of laptops - they no longer offer "UltraBooks" the 12700 is going into a new class of laptops called "MeltBooks" !!

Check out the new videos on YouTube of the 6900 running Forza at 4K on the iGPU - thats 4Y away for Intel which struggles at 1080p !!

Once again... why waste all that money on the top-of-the-line CPU and then cripple it?

Yes, you can game on an iGPU... but why?!?!

As for unsubscribing... don't let the door hit you on the way out :)
