Does anyone here have a Ryzen 5000 CPU?

Curious about the new Ryzen.
Code: Select all
31.045.535 AMD Ryzen 5 5600X @4.55Ghz 12threads BMI2 Monstru

The 4000U series are not for maximum computing power - these are low power chips. The 4800U in particular is kind of a unicorn to actually buy, but 4700U is easier (that's a 4800U without SMT). For maximum speed, you'll want 4000H - but obviously, you cannot expect any useful battery range at full load, so that kind of usage will be half-mobile with AC-supply. That's the same with all laptops, also Intel ones.
Your first choice is Intel vs. AMD. If AMD (and that's a good choice these days), it's either the U series for mobility and battery range, or the H series for performance. Next, you have to choose whether you want a dedicated graphics card, or the CPU integrated graphics. The latter is suited for everything except gaming, i.e. office, web, watching videos. I have a 4700U laptop with integrated graphics only, and it runs nicely under Linux.I think I'll go for Thinkpad with powerful Ryzen. What powerful laptops am I missing? No gaming laptops.
Thanks a lot!Ras wrote: ↑Sat Jan 30, 2021 1:53 amThe 4000U series are not for maximum computing power - these are low power chips.

With the 5000 mobile chips, you'll need to watch out. There will be 5x00 with odd x (5500, 5700) with are basically re-labelled 4000 chips, i.e. still Zen 2. A 5700 will however be equivalent to a 4800, not 4700, i.e. with SMT. 5x00 with even x will be Zen 3 chips. However, the number scheme within 5000 will be so that higher numbers within the 5000 range will mean more speed. So, a 5700 (Zen 2) will be faster than a 5600 (Zen 3) due to more cores.

BUT! keep in mind that LC0 style NN chess engines basically require an Nvidia GPU because AMD is light-years behind with regard to software. AMD is still fighting to catch up in gaming while Nvidia has taken the ML market long since. If you want to run such engines, a gaming laptop can be back on the menu.
The next question is, when do you want to buy? AMD has presented the new 5000 mobile chips just last month, and under ideal circumstances, they could hit the market in March. Last year, AMD had massive supply problems. This year, they have ordered more chip production capacity at TSMC, but the whole semiconductor industry is in supply turmoil even over everyday components. I don't expect 5000 Zen 3 laptops in numbers before mid-year.
Another point is that the 5000 chips with even numbering, i.e. the Zen 3 ones, can be expected to be scarce. That's why AMD tries to mix in Zen 2 chips into the 5000 numbering. The laptops with Zen 3 5000, i.e. like 5600/5800, will be for high end gaming and workstation laptops. Don't expect to see a product like 5800H without powerful dedicated graphics card even being announced anytime soon.
I wouldn't expect it that soon, but of course waiting for half a year will always buy you better hardware.
While 16GB look fine, keep in mind that integrated graphics grab a part of the main memory, and Thinkpads have soldered RAM so that you'll need to buy a model that has 16GB right away. On the other hand, if you want a 14" laptop for work, you'll probably also want a docking station, and Thinkpads offer that.My plan is use that ThinkPad(4800U + (8+8)GB) as my only computer for the next 10+ years.
That leaves Thinkpad T14(AMD) or T14s(AMD). The delivery time for the built-to-order models is more than 5 weeks, so that's probably out of question.I only need 14". That integrated will do just fine.
For the Ryzen 4000 Renoir integrated graphics, kernel 5.8 or higher is required. No prob with rolling release distros such as Manjaro, but also Ubuntu LTS has that in the HWE (hardware enablement) kernel, and by consequence, Mint offers the same. Mint 20.1, which I'm running on my 4700U, has even a download ISO with 5.8 kernel (Cinnamon Edge). The Intel AX200 wifi that the T14(s) have works well with the 5.8 kernel - I have the same wifi card.Linux of course. Mainly work.
Yeah, 4700U has eight cores, 4500U only six. 4800U has also eight cores, but with SMT (AMD's hyperthreading). However, for the 4800U to deliver more punch than a 4700U, you'll need to run more than eight worker threads at the same time while not being I/O limited. Also, the Thinkpads T14s don't seem to be available with 4800U, and the Ideapads or Yoga Slims that were with 4800U are out of stock as far as I know.Looking at this. 4500U vs 4700U vs 4800U. There is a bit difference.
I find 58.501.924 value for AMD Ryzen 9 5900X 24 threads even more impressive. It's not only faster IPC but also BMI2 finally working (it's 5-8% speedup compared to pop compile).Dann Corbit wrote: ↑Fri Jan 29, 2021 9:54 pm I don't have one, but one of them was benchmarked on Ipman Chess:Code: Select all
