Just for context , Zen 4 was ~10-12% uplift with some minor tweaks versus Zen 3. If Zen 5 ends up being just 10-15% faster at iso clocks versus Zen 4*, then something went wrong in the design process. AMD has such advanced internal performance modeling tools that I find it impossible they would...
In a way that people who designed it disagree with you, and I tend to believe them more:

For Zen 1 it's a huge uplift versus previous core and a major redesign - they used bits and pieces from BD and...
Here are two average samples of Zen 4 with different L3 capacity that boost to same 5Ghz. 32MB version gets around ~5% higher integer score (on Windows).
https://browser.geekbench.com/v5/cpu/22296464
https://browser.geekbench.com/v5/cpu/22313699
Total score.
I just checked integer scores of two STX samples:
https://browser.geekbench.com/v5/cpu/22424015
Integer Score 829 @ 2Ghz
https://browser.geekbench.com/v5/cpu/22427061
Integer Score 1011 @2.33
It looks like the second sample scores 5% better than what GB5 data...
I checked his 2G results and the scaling to 5.75Ghz is 0.952x (from a perfect 1x). Which aligns with 25% vs 30% uplift that I calculated.
You can check GB5 browser for 7500F vs 8600G ST results - it's full Zen 4 with 32MB of L3 vs Zen 4 with 16MB L3. The difference is around 5% as they boost...
Correct me i I'm wrong but 2.33Ghz sample with half od the L3 cache (16MB) scored 1224pts in ST test. If it scaled perfectly to 5.7Ghz it should score 5.7/2.33 x 1224 ~= 2994 which is 30% higher than what DisEnchantment gets ( with Zen 4 that has 2x the L3 and running an optimized bios with good...
20% in *some* MT workloads ,and 5-10% tops in ST workloads vs the old RPL-R (another slide claimed ~5% ST uplift vs RPL). My guess is it will get crushed by Granite Ridge, but let's wait and see.
They are referencing the old "news" from RGT... Not really reliable, just like MLID. I'm not saying I don't believe the numbers could end up being in the same ballpark, just that these news sources are dubious.
I still remember his BS claim about Redwood Cove having 20+% IPC increase (it has actually close to zero IPC increase)... That was a true facepalm moment. Maybe someone trolled him with that fake info as well, it's possible. The guy is just hilarious, and he still thinks he has real sources.
No, the poster was implying the average IPC is 3x% ( meaning between 30 and 39%). Clocks seem to be roughly the same or a slightly higher for ST with Zen 5. Overall it looks like a total pwnage.
The above scenario is "real" in the world of a die hard that clings super hard on a dream that ARL will be competitive (somehow). If the dream is dead, they have nothing for 2 more years.
I'm now almost certain that ARL will be DOA, we now have multiple people claiming that Granite Ridge will be clearly a faster product. If that is true, we'll have to wait until 2026 for something competitive from intel on desktop.
You have to adjust for the difference in clocks for both Zen 3 and Zen 4. Once adjusted, the difference is about 12-13% in favor of Zen 4 (per core, per clock, average of all subtests).
For Zen 2 vs Zen 3, the average is exactly 19%, just as AMD claimed.
Points per watt for ST results is not valid as we cannot take the total TDP when calculating that metric. ST power draw is very different for all those CPUs.
With imminent launch of 14900KS, which has around 5-6% higher ST boost versus 13900K, I wonder how will Arrow Lake do against this SKU. Igor's lab and other leak (slide) pointed to ~5% ST increase versus 13900K. If that is still true, then Arrow Lake will have a hard time beating 14900KS in ST...
I think that was supposedly done on an ES that had clock regression (which is supposedly now addressed).It would be really crazy to see Zen 5 clock the same for 1T as Zen 4, with all the stuff they added/changed. But AMD did it with Zen 2 -> Zen 3 on the same node, so it would not be unheard of.
Well he stated 10-15% IPC improvement (not ST) according to that slide he leaked last year. I don't know what else he claimed since his range is absolutely degenerate (as always) - this is how he can claim he is spot on.
My guess is that Zen 5 will have similar ST jump as Zen 4 (vs Zen 3), so...
The Redwood Cove IPC leak was priceless. He even apologized for the "huge range". Dude, how about there is no range LMAO
I think he gets scraps and pieces from some insiders but no tier 1 sources. He is basically farming likes/views with sensationally mostly made-up content.
That is not correct. 1T results in Cinebench do not correlate with SPEC 1 rate when it comes to Raptor Lake and Zen 4 (which are basically neck and neck in Spec but Raptor Lake leads in Cinebench). I'm referring to the performance per clock.
I guess it's time for my likely very wrong performance projection for Ryzen 9950X :). The streak was always going to end, why not with Zen 5.
Link to the doc ( I reused my previous doc for Zen 4 projections with very minor adjustments)
Computerbase data
Zen 5 core to have...
I think it is up there with Conroe and K7.
Here is mine, nostalgic screengrab from an ancient CPUz version, seen as K19!
I run mine at CO -30 and 125, 80, 115 limits. Runs crazy good, knock on wood. Went from R5 1600 to this, quantum leap in performance lol.
@bender250
I did post a few times but I didn't have time to do a bigger post like in the past :(. I will try to do it before this thing launches, but this will be the toughest one to predict and probably where my lucky streak ends :D
OP can check the computerbase ranglist here: https://www.computerbase.de/thema/cpu/rangliste/
For workstation use, 7950X (non 3D) is around 3% faster than 14900K.
This is now pure desperation from intel's side. From AMD being "left out in a rear view mirror", to these pathetic performance and perf./watt numbers from "game changing" MTL architecture, they are losing the plot.
