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
8 stands for 2024 btw.
The 4 means zen 4
Thank you AMD for a totally not confusing naming scheme for laptops.
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.
You have former and latter mixed up
Fixed!
A 12900K also beats a 13400f
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 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.
I mean, thanks to that you know that’s its refresh. So it’s fucking helpful.
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)
Yeah the real improved version should be called 8050U
Uhh, no?
