can AMD stop making EXCELLENT CPUs!!!! /s

Why is the 9800X3D so gooood!! 27% increase over 7800X3D in GB6 ST @ 5.4GHz.
This is a 2 generation upgrade over my 7700X. Will I upgrade? I thought of upgrading when Zen6 is out but I will do it next year cause this is a massive improvement. This CPU will be killer for Flight sim 2024.

Well, you know the Turin is 40% better than the Genoa ! Zen 5 just kicks butt ! A lot of that is increased clock speed. With a smaller die size and improved clock speed as well as design thats where the 40% comes from. Now if I can just get my motherboard for my Turin, I could do some benchmarks and show you.

Edit: You remember the 40% Zen 5 claim that was make ? It was based on Turin, but desktop did not get that (you can't extrapolate was the lesson)

Lower freqs in R23 than R24. Does ~31.5K @162W, CCD0 (4.97G) gets a bit faster than CCD1 (4.88G). R23 more strenuous than R24, apparently.


Also, I ran Dolphin Bench 5.0. Apparently Zen 5 is the top dog in that benchmark. Wonder how Arrow Lake does?

this is 7700X stock for comparion.

From another thread, if anyone wonders ... not bad in light of other gaming results (regressed less than 3% )!




Here is my 9950X with DDR6100 CL30, PBO 225W, CO1 -20 CO2 -30 and 102FCLK on Windows 10 Pro

Or it is just copy & paste from old Milan-X BIOS specs or documentation. This Asus "AMD TR5 Series BIOS Manual (English Edition)" which Videocardz cites is from December 2023 by the way.

The part of the article which refers to the "1 stack/ 2 stack/ 4 stack" choice is contrary to what has been said at other sites about it in the past: Supposedly, this doesn't mean the CCD count with stacked cache, but the layer count of stacked cache per CCD. Back then it has been said that >1 high cache stacking has been developed by AMD but not brought to market. I don't recall where this was claimed.

My Dolphin Bench 5.0 run looks abnormally fast compared to the run shown above. Can you run yours to verify? I am using a +50MHz -20 CO offset on my 3 fastest CCD 0 cores, -10 offset on all CCD 1 cores but that still seems like something isnt right. I ran twice with identical score each time.

Maybe you got an abnormally good sample?

How about trying with only one CCD at a time? Is there a performance variation between the two CCDs?

Also, you should submit your result here: https://forums.dolphin-emu.org/Thre...enchmark-results-automatically-updated--45007
I dont think my sample is anything special based on CPU-z, Cinebench 23 & 24, its right there with other reviews results, even a bit lower in some cases. My 3500/22K GB6 score was tuned up a bit, my daily low effort default PPT (162W) optimized settings are ~3475/21.5K. I just want to make sure nothing fishy is going on with my test here. The difference between mine and the other chart posted seems to be more than margin of error.


As for submitting the result, I did. Sort by overall time in seconds and look whats at the top. (Didnt use my name though, couldnt remember my login).

Where is the link to see where all these Zen 5 ?? I want to see the master list from the source. And the source post where I can run this myself ?

Based on the average clockspeed for each core as indicated in your HWinfo screenshot your Zen 5 is producing 545.8 points/GHz in CB R23 MT.

Based on the info Josh128 provided his Zen 5 is producing 533.0 points/GHz in the same test. That is an error of 2.4%. Since I could actually use HWinfo data in your performance calculation I think 546 is a good representation of what Zen 5 can do with CB R23 MT.

I have read 9950X reviews where they are benching the 9950X at around 40 to 41k for CB R23 MT, like the one I linked below.
This would put the frequency at 4.60GHz. Why are some review sites getting such low clocks with this bench? It is hard cooling-wise to run the 9950X at 5GHz or higher in CB R23 MT?

I'd love to see the progression of Zen through CB R24 MT/ST since that's the newest version.
If you have a Zen 1-5 and want to post CB R24 MT/ST benchmark data, I'll compile the results?
Just include a HWinfo screenshot during the run showing clocks for both MT and ST runs. Also be sure to reset the HWinfo counter right after the run starts.

Mods - Would this be something I should/can post in the CPU forum instead because then I can include other CPU cores?

i think its more viable now with the improvements to clock rate with zen5s new cache die arrangement. TR always had very boost clocks compared to full on server parts.
Knowing AMD, wouldn't they start with porting Genoa-X over as a Threadripper product? Starting with Turin-X would be unexpected.
