I don't think It's a big market.
I think the better question would be how many phx were made.
Putting it another way: OEMs' demand for PHX in handheld factors appears to be much higher than putting those in existing laptop models. Can only guess that the former is a potentially very lucrative new market for them while the latter is kept less dynamic by existing long term contract obligations, marketing payments by Intel or some such?

The 7840u has been in very short supply, and until recently, hard to catch.
Lenovo, HP, Asus... all of them had their machines with the 7840u backordered.

Kind of makes you where all that supply is going? It can't all be handhelds.

Possibly a dark horse handheld? Wasn't there rumors about Microsoft having an Xbox tablet of some sort? I think it might have just been a prototype but maybe they've seen how popular these and the Steamdeck have been and decide to try and capitalize. Especially to showcase the rumored handheld tailored version of Windows? Maybe also ASUS or someone bought up a ton, I expect we'll see a lot of designs to tout their purchase of the NUC division.

Another thought, maybe a new Steambox?

My guess is they limited things some to prep for products touting the 8000 series at CES. If companies are smart, they could sell a lot of laptops with these if they have TB5/USB 4 Gen 2, Oculink (or ASUS version), to pair with eGPU. Will let them boost margins, and they should be fairly drop-in for many designs. Remove the lower level dGPUs and put in larger battery which will make them look better as portables, and better eGPU means they can put the hot GPUs outside the chassis and charge more for them (see ASUs XG Mobile and others like the Khadas Mind).

The availability issues did not appear to be related to 7840U availability, at least for the large OEMs like those you mentioned.

Take Lenovo as an example. They announced several machines with imminent availability, yet deliveries beyond a trickle were pushed back months. Not only does a major partner like Lenovo get the units from AMD that they ordered ON TIME EVERY TIME, they would have already had enough units on hand for the initial wave of customer shipments.

A much more likely explanation is a late QA issue. In comparison with chips from AMD and Intel, all the other chips that go into a laptop are much less rigorously tested and often shockingly poorly documented, so my bet would be with one of them. If you really pushed me to hazard a guess, I would say the culprit is likely something related to the sleep problems that plagued those early shipments (resolved now with "BIOS" updates that included updates for non-AMD embedded microcontrollers) or the possibly related high idle issues (also mostly resolved).

Phoronix recently had one of the best processor reviews I've seen in a good while, mainly because it includes power draw plots for a lot of the benchmarks. The review compares Intel's Core Ultra 7 155H with the Ryzen 7840U (Acer 14" Swift Go 14 for the Core Ultra, Framework 13 for Ryzen). The 155H is nearly identical to the 165H (4% higher max boost clock on the P cores, 2% higher max freq on the graphics), so the results should transfer very well to the 165H.

The 155H and 165H are Intel's most direct competitors to both the 7840U and 7840HS (and thus 8840U and 8840HS). Power consumption and cooling solution matters a great deal, especially when it comes to mobile benchmarks, so including power plots is a very nice detail that most reviews sadly do not offer.

This is Phoronix, so the benchmarks are run under Linux and cover a wide range of workloads, so if you know what type of workload you are running, the overall scores don't matter and you can check your specific workload type in the 370 benchmarks.

The results show quite a different picture than what Geekbench would have you believe. The 7840U wins about 80% of the benchmarks with a nearly 30% higher geomean. The Ryzen also uses significantly less energy in delivering that performance.

Good read. Funny colors on the power, green vs slightly darker green. Feel really sorry for the colorblind. Edit: or is it a Blue Green? Edit2: maybe the green is a yellow green. Maybe going colorblind in my old age. Nah I just need a more expensive monitor.

Hey! Hold up there buddy, we prefer color challenged! :p If I zoom to 200% I can read the Linux test benchmark suite on the first page.

It's good that you've observed the true value of Phoronix benching, which is to look at whether or not specific workloads pertain to your use case and then gauge performance accordingly. The Phoronix Test Suite has a lot of software in there that may not be relevant to many laptop users. Not that I'm arguing that Geekbench is any more-relevant (I'm not), but the geometric means that Phoronix publishes can be a little misleading. In this case it favors AMD, but that isn't always the case.

It is interesting that the 155H showed up badly when it comes to power consumption in these tests.

It is also interesting to see how many of the AI benchmarks performed far better on AMD's aging hardware.

So Phoenix (the big one) doesn't have any parts with just 4 cores?

TSMC N4 yields must be too good.
TSMC N5/N4 yields are excellent, however that has nothing to do with it. AMD almost always releases budget/low margin products last. This keeps them from competing with themselves.
I don't think It's a big market.
I think the better question would be how many phx were made.
The Steam Deck has sold millions of units. ROG Ally has also performed well.

After a year Valve sold 3-4 millions of handhelds.
Can <=5 million of sold handhelds per year be considered a big market when PC(Laptop + Desktop) sales are ~250 million per year? That's only 2% of total.

edit: fixed my mistake.

Price is $20, 30 bucks cheaper than I thought it would be. The 8700G is the same price as the 7700 Non-X at Newegg ($329) and the 8600G is the same price as the 7600 Non-X ($229).

If it's easy money it's easy money. New markets (which handheld PCs essentially is, as popularized by Steam Deck) tend to be easier money than gridlocked older markets.

It is quite expected, that today in 2024 for retail customers 6/12 APU or R5 8500G will be as a minimum.


R3 8300G is still expected to be sold in classic retail in the future during 2024.

180$ or euro for R5 8500G, it is ok price in today global situation.

Big jump in iGPU frequency, old 8CU Vega 2ghz vs RDNA3 12CU at 2.8-2.9ghz. :mask:

yeah... we are still waiting on the 5300G/4300G. And the 8500G is way too expensive for what it is, $50 difference to the 8600G for double the igp and much better MT performance? it is mostly an 5600G with better ST perf that does not really matters that much because only two cores perform like that.

AMD already released 5500GT as a lower-tier option without cutting anything out (compared to 5600G). now it's 5700G > 5600GT > 5500GT > 4600G > 3400G > 3200G > 3000G
I doubt AMD will release a quad-core Zen2/3 APU because the full die is 8 cores and it'd be kina wasteful. Also quad core Zen+ is still there (Win 11 supported).

Not everyone who buys APUs is an iGPU gamer, shoker i know. It would actually be of little value for those people to upgrade to 8600G

ST perf matters a lot

But they are releasing it to OEMs? The OEM market is smaller than consumer market?

Thats up to the user, but the direct comparison to older AMD Ryzen 5 APUs is valid and reasonable.

Yes when all cores perform the same, here only 2 cores performs like that, the other 4 due to clock limits are considerably slower.

Giant OEMs and Individual DIY'ers are so far apart from each other that I won't even start explaining differences.

The comparison to 5600G is valid, and we'll soon see test results, both on the CPU and GPU side. But it's clear that small phoenix wasn't made to be a "gaming APU", but an APU tha can game, similar to Intel's uhd graphics

Not all cores clock at 5.0 GHz at the same time even on 8600G, I think MT perf will be that of a full 5-core maybe, small difference.

The weirder thing I wanted to mention is crippled PCIe. small phoenix has 14 PCIe lanes, 4 are used for the GPU, 4 for the chipset, 4 for the primary NVMe, and the remaining 2 is for secondary NVMe. There should be some test done with a 4070 and 8500G/8600G

Same again, not expensive for a "new AM5 socket" or a very good efficient 6/12 APU for a HTPC PC or similar usage.

In today's global situation, 50$ or euro is not a small difference, quite the opposite. Look at what you can buy for that amount, or close to it.16gb DDR5 memory, or 1TB NMVE SSD.



R5 5600G, no need to comment. Except that it is located in the apparently indestructible and eternal or old AM4 socket.:mask:It's hard to compare old and new, especially when the R5 5600G has no AV1 hardware decoder.
