The most important change was the inclusion of Precision Boost 2 which was first introduced for the Raven Ridge APUs. Where the 1800X has a single hard boost step from 4.1 GHz* down to 3.7 GHz for more than two active threads, the 2700X has the gradual opportunistic boost that's still used...
Watch the JayzTwoCents video. Apparently the problem isn't new, and his fix was for Zen 4. Moves the game to VCache CCD, keeps background stuff on the frequency CCD.
There would've been an easy to fix to get better reviews: 8-core Ryzen 5, 12-core Ryzen 7, and just the lower Ryzen 9 with 16 cores. And announce a cheap 6-core Ryzen 3. Also, keep everyone waiting for what might fill the 9950X spot.
He also says that despite 65W TDP the CPU goes up to 88W "for bursty loads", which show a complete lack of understanding for how power limits on Ryzen work, but...
...this might actually be a blessing in disguise because with that lower clocked memory we get to see 4.65 GHz all-core @88W where...
That someone was me. And yes, they usually measure package power, but for that specific measurement they only measured the cores. It's described in the text. How about just using auto-translate:
And yes, I still need to point out the "four cores" mistake to them. That's 8 cores for all the lines.
No, the 60W number is for the cores, without SOC. Add the 27W and some change for the correct 88W PPT in total.
And yes, the 27W indeed seems excessive, considering they used RAM at JEDEC timings, so the memory controller should not be in OC mode.
Those two are not the primary sources in Germany. The swing towards higher efficiency and lower temperatures is reflected much more positive over here where electricity costs are much more relevant for buyers. The fix for all those "too hot" posts was usually "use eco mode".
Where Zen 5 actually shines is temperature:
That's -35°C from 7700X to 9700X and still -15°C when both are running at 142W PPT. Thank god, this will hopefully end the thousands of "my CPU is running too hot" posts in German forums that I had to endure for Ryzen 7000 during the last two years.
First of all, you can with regular Zen 5. Apple silicon is not a mobile-only solution, and so isn't Ryzen.
And for Strix, perhaps not put it on a board yourself, but I wouldn't bet on not being able to combine it with a 4090. Minisforum might put out something like this with pre-installed Strix.
Regarding PBO, wider cores, and how much performance is left on the table for the 9700X:
This shows the wattage provided for the cores when using 88W or 142W PPT. The limit for the cores is always lower than the overall limit. The 7700X (blue) isn't limited during full load when using 142...
The SKUs have one problem: Despite apparent price reduction to the previous generation, they are too expensive:
If we apply the Scooby Doo Unmasking meme to the 9700X and 9600X, and correctly name them 9700 and 9600, then they are reaching the market at 30 USD more for the 8-core model and...
Also, for a good share of enthusiasts, Apple silicon is completely irrelevant. If you can't buy the chip, put it on a board and combine it with a high-end graphics card, then it might just as well not exist.
The "Text Processing" subtest scores ~3070 in ST and ~3800 in MT, which basically means it uses no more than 1.25 cores. The number of available threads is meaningless in this. Even a 96-core Threadripper only gets 3076 points in MT. On the other end of the spectrum is "Ray Tracer" with ~2600 in...
Thank you. I also had those statements still in mind but couldn't remember which interview it was. The interesting part about Zen 5c starts at 8m20s. Mehesh even envisions the separation of CCXs and thus cache contexts as beneficial for applications with different performance requirements. It...
Something like this. The argument for the Snapdragon was lower prices but so far that hasn't really materialized. At least in the EU the cheapest X Plus models are still around 1100€, with X80-100 Elite models mostly around 1500€, right where the cheapest HX 370 models are starting on launch...
Sorry that I have to repeat-feature that in this thread, but David Huang already measured bad latencies:
That's worse than with Ryzen 1000 (had to search a bit, the earlier discussion of this was from PC Perspective):
The darker purple HX 370 ones are from two different models, one more geared to being quiet, one towards higher performance. The X Elite numbers are estimations since HWiNFO still has no way of reading package power for the Qualcomm chips. So JustJosh had to go from wall power readings and then...
Yeah, it's really strange. He even talks how "the ones with the lines" were laptops where they tested all power levels on the same device, and then doesn't notice that this puts the white line in a strange spot. Later, he explains how with Apple you basically can't change the power consumption...
I think you can remove the question marks. For the 12-core it fits, for the 11-core it's a bit low. Basically the strange shape of the curve is due to their low 11-core result. But there are no other models, ore are there?
Yeah, but then that's a complete fumble on AMD's side. Pushing AI in every single presentation and then having nothing to show on release. As usual, they did everything for Microsoft only for Redmond to completely ignore them regarding CoPilot+ support. But it would have been nice to at least...
What I'm taking away from the first Strix Point reviews is that AMD was talking about its great AI capabilities and the NPU with 50 TOPS non-stop, and yet I find exactly zero benchmark results that use said NPU. Did somebody find anything where the NPU was actually tested?
I think it was a conscious decision. AMD saw that People are buying the X3D models not just because of good performance in games, but also because of being so efficient. This is all over the forums, at least in the EU. Ryzen 9000 brings higher performance at lower power consumption. Freeing up...
That's 28% faster in Blender with the 7700X at 142W PPT and the 9700X using PBO. That's +11% from 7700X@142W to 9700X@88W and +15% from activating PBO on the 9700X. Compare this with the 9950X which has 22% at the same 230W PPT and gains another 6% for a total +29% when activating PBO. This also...
Dont' forget that Ryzen 9000 has lowered TDP for most of the models. All models below the 9950X basically default to what was the Eco mode before. Look at the right side of this slide:
The 9700X gains only 11% and not 22% because it's the SKU that's limited the most by its lower TDP compared...
They are guessing. They see AMD recalling all units and announcing that they're replacing it with a fresh batch and jump to the conclusion that it must be a hardware issue.
But that's not necessarily the case. The "didn't go through QA" explanation works just as well. It's simply faster to...
Going from how omnipresent the 9900X is in marketing and product listing leaks, and the first early review also being on a 9900X, I very much doubt that.
