Does anyone here have a Ryzen 5000 CPU?

Curious about the new Ryzen.

I don't have one, but one of them was benchmarked on Ipman Chess:

Code: Select all

31.045.535	AMD Ryzen 5 5600X @4.55Ghz	12threads	BMI2	Monstru

I'm in the market of new laptop. Is Ryzen 4800U good enough or are Ryzen 5000 coming soon?

I was about to buy new Lenovo Yoga Slim with i7 (4 cores) but that thing only has USB-C. Hell no. No Apple too. I think I'll go for Thinkpad with powerful Ryzen. What powerful laptops am I missing? No gaming laptops.

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.

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.

I think I'll go for Thinkpad with powerful Ryzen. What powerful laptops am I missing? No gaming laptops.

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.

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.

If you look up above, 30M NPS for 12 threads is eye-popping.
I guess that machine might be pushed a bit.

I bought a Ryzen 3900x, because the 5000 series is very hard to actually get hold of. You can buy them on eBay for big markups. The 3900x is practically just as good though for most uses.

Thanks a lot!
I haven't been following HW for a long time. So this is great help. If I buy now then next week Zen 3 arch laptops are roaming stores is my fear.

My plan is use that ThinkPad(4800U + (8+8)GB) as my only computer for the next 10+ years. So there needs to be enough kick. Good cooling too and good casing. Not cheap plastic. I might pick it up next week and sell my old crap for peanuts.

GPU programming is interesting. But gaming laptops are almost all 15.6"+. I only need 14". That integrated will do just fine. Of course I won't accept any dead pixels. My old laptop has dead pixels.

Linux of course. Mainly work. I only play a little bit Xonotic time to time. IMHO which is the best open source Linux game. Good graphics. Very few players unfortunately. I'm already getting 120FPS with really crappy desktop with low settings.

Looking at this. 4500U vs 4700U vs 4800U. There is a bit difference. I'm not gonna save any cent with CPUs: https://www.notebookcheck.net/R5-4500U- ... 596.0.html

I wouldn't expect it that soon, but of course waiting for half a year will always buy you better hardware.

My plan is use that ThinkPad(4800U + (8+8)GB) as my only computer for the next 10+ years.

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.

I only need 14". That integrated will do just fine.

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.

On the other hand, the pre-built models of the T14(AMD) range cap out at only 8GB RAM and 256GB SSD, and that's ridiculous, so that narrows it down to the T14s(AMD). The only pre-built T14s(AMD) that comes with 16GB RAM is the one with 4750U, so that answers the question which CPU to choose. The 4750U is a 4700U with some business administration features.

Linux of course. Mainly work.

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.

I'm not sure whether the keyboard backlight will work OOTB under Linux. For mine, I had to install a custom driver, but since I did that via DKMS, it installs automatically upon kernel updates, so that's nice. Thinkpads maybe don't need that.

Looking at this. 4500U vs 4700U vs 4800U. There is a bit difference.

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.

I don't have one, but one of them was benchmarked on Ipman Chess:

Code: Select all

31.045.535	AMD Ryzen 5 5600X @4.55Ghz	12threads	BMI2	Monstru
30.951.403	AMD Ryzen 5 5600X @4.55Ghz	12threads	pop	Monstru

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).
Maybe it's finally time for an upgrade since previously it made no sense with 3900X having only marginally better performace on 24 threads to my dual E5-2689 system on 32 threads with 9 years old CPUs.
However, it would take who knows how long before 5900X becomes really available in stocks.

What engine is this ?
