8 stands for 2024 btw.
The 4 means zen 4
Thank you AMD for a totally not confusing naming scheme for laptops.

For all things AMD; come talk about Ryzen, Radeon, Threadripper, EPYC, rumors, reviews, news and more.

I fucking hate how they name this shit.
Can you believe some people actually defend it?
You already have situations where 7520u (zen2) is slower than 5600u (zen3)
Soon you will get a R7 9730 slower than R7 7740
Or a 9520u being lower than 7540u
I mean, it tells you right in the name it's zen 2. The actual issue is it's 4 cores despite being ryzen 5. The 7320u also has 4 cores.
and then zen5 laptops will conveniently not launch until 2025, so that they don't end up with a bunch of 25% better performing laptops advertised in the spec sheets only by having the 3rd digit one number higher than other models
They csn refresh them next year, so no problem
A 9840h would be slower than a 9750H
I had to look up that chart yo name them. That's how bad it is.
How is that relevant? A refresh of a 8750 would be 9750 as it's the year that changes.
It's not my fault you don't know how the new naming system works yet. Someone who didn't know how the old naming system works would also have to consult something.
You think the general public will know?
It has always been first higher number representing latest generation.
Not the 3rd
No it has not.
It was amazing when zen3 mobile came out and they had even second numbers be zen3 and odd zen3 numbers be zen2. :D Except 9 was ofc zen3.
https://www.pcgamer.com/amd-ryzen-5000-mobile-laptop-architecture/
5800, 5600 and 5400 zen3
5700, 5500 and 5300 zen2
That was soo much better, right?
Yes.
R7 5800 8 core > R7 5700 8core
R5 5600 6 core > R5 5500 6 core
R3 5400 4 core > R3 5300 4 core
You quite literally gave the best answer of why older names were better.
No, you said first number was always last generation. That was pure ignorance and now you are moving goalposts and trying to win by arguing something else.
New names have both the release year and generation in them. You see it in a glance. You see 9840 is zen 4, so you do not accidentally buy it f you only want zen 5.
The two last numbers tell you the product segment, and the second number is how high it is in that segment. Just learn the system.
It still does.The 5000 is still better than 3000.
That's just facts. Also its a massive change that in the 5000 series, both zen 2 and zen3 are made on the same 7nm.
You cannot say the same for new naming.
7020 and 7030 is on 7nm processes (6nm and 7nm). The exact same as ryzen 5000 and 6000
7040 is on 5nm processes (4nm and 5nm)
They don't belong in the same category at all. The nodes make it quite obvious. They are selling you old and significantly less efficient nodes.
The name is a way to sell old zen2/zen3 cpus as brand new.
Why do you think this is only for laptops and desktop haven't gotten this?
Because you average consumer mostly buys a laptop over desktop and they will have no idea.
What's so confusing about it? Isn't the naming convention public info? So those that care about model numbers can look up what's what - or am I missing something?
The issue is that it breaks the commonly accepted trend of bigger number better. You could have an 8520U get clapped by a 7540U for example, because even though the latter is newer, the former is Zen 4 to its Zen 2.
A 12900K also beats a 13400f
You have former and latter mixed up
Fixed!
You could have an 8520U get clapped by a 7540U for example, because even though the former is newer, the latter is Zen 4 to its Zen 2.
Absolutely completely irrelevant!
Show me a laptop line with these both in them. They are for completely different type of products.
You buy laptops, not laptop cpus. If you are looking for something to game on, you will not even see laptops with mendocino on them.
They had to change the system as they now have multiple different types of cpus instead of one they had different numbers of cores for.
The 7540U is a 28W Zen 4 part. If the 8520U exists it will be a 15W Zen 2 part.
At the 15W and below TDP range performance won't actually be as far apart as you would think, you can see this with steam deck vs rog ally performance at 15W or lower TDPs.
The way to think about it is that there is the 20, 30, 40, and 50 series with bigger being better and within each series you have the model year (7/8/9 etc) and the tier of each part in the series.
For example, which TV is better. S95B or the S90C or the QN95C or the S95C?
Bigger problem than any that has been mentioned is that there is now 45 series that is desktop cpus on laptops. So I really hope they will stick to HX being just for that category or it will be a mess. :p
I mean, thanks to that you know that's its refresh. So it's fucking helpful.
First number is for the year, so this is prety much a 7040HS/H/U renamed for the year 2024.
It's a traditional AMD's rebrand/refresh.
Trinity-Richland
Kaveri-Kaveri Refresh/Godavari
Carrizo-Bristol Ridge
Raven Ridge-Picasso
Renoir-Lucienne
Cezanne-Barcelo
Phoenix-Hawk Point
Sometimes this spans even three generations
Raven Ridge->Picasso->Pollock
Cezanne->Barcelo->Barcelo-R
Yeah the real improved version should be called 8050U
Uhh, no?
I need a 4 series Thinkpad with a 16:10 display and a 12 CU RDNA3. A man can dream...
They are on sale for about $1k (US) right now. May have to look hard to find the 400 nits low power screen. $1026 for 7840U/400 nit FHD+ (OLED option +$119)/32 GB/256 GB/finger print reader/52 Whr battery -$100 if sign up for emails. So $900-ish plus tax w/non-gaming screen or $1k-ish+ tax w/OLED. You can upgrade the SSD yourself as they want $150 for 1 TB 9$45 for 512GB)
