AMD Ryzen 7 9800X3D Comes with 120W TDP, 5.20 GHz Boost, All Specs Leaked

I like tuning CPUs.

And tuning X3D is boring AF.

Now it wont be, hopefully.

If you like to run your CPU at stock, all the power to you.
 
I stopped tweaking CPUs a long time ago, the last CPU I ran overclocked was the Intel Q6600, so a very long time ago. CPU's these days have sod all overclocking headroom as they tend to run not that far from their max potential these days, same for the GPUs, so for me stock speeds are fine. Seems these days it's gone from overlocking to undervolting instead, which I've never bothered to get into. If the system is rock solid, fast and stable then that's good enough for me :)

That isn't entirely true, there is performance to be had if you know what you are doing;.

I am not here to judge, I am here to play with hardware with other like minded individuals :)

Well, CPU/GPU manufacturers found out that doing OC on previous generation product along with applying minor tweaks can easily be released as next generation product, no significant changes in architecture required. But we saw with Raptor Lake how that might strike back if you push too hard. It's as you wrote, now it's mostly about optimizing efficiency - undervolting. To me it seems it's not less fun and is also safer to play with. Provided there is a sufficient cooling measure in place, you can't damage CPU/GPU when lowering voltage or ramping up the clocks - the chip might become unstable, cause a system crash or freeze or smth similar. Undervolting will not only lower power consumption, but also temps and lower temps equals to less noise.

Personally, I'm not feeling comfortable when I know that with proper tuning and not so much effort my system might work at much better conditions, especially noise-wise. There are people who tune their chips to reach the efficiency sweet spot, which basically requires significant lowering of clocks. I am happy to go with stock clocks at as low voltage as possible, this usually lowers temps and noise significantly.

Or maybe they've just run out of ideas of how to make significant improvements without raising power and/or cooling needs significantly.

Or you could just buy a one tier lower CPU and run it at stock.

To me it seems like they are trying to save money in wrong places, like in R&D. Without proper R&D, there won't be so many new ideas and new inventions.
They should spend less on marketing and other non-crucial company stuff. I really can't understand Intel's decision to lay off people also from R&D. This will backfire badly one day.

No way! I want my life to be complicated.

Without being able to peek into the daily grind at these companies, I guess we'll never know.

Ehm... ok. :roll:
 
I would say post alder lake on intel and 7800x3d class performance on AMD is still useful without the best GPUs and without even wanting high frame rates, but this depends on the games you play, lightning returns can only hit stable 30FPS with that kind of CPU grunt. It will still dip to 30s at 60fps target in some areas, probably needs another decade of CPU development before it can sustain 60 everywhere. Or hopefully a remake of the game thats better optimised.

What I have noticed is newer games seem better optimised for CPU's (more threads), but older games are much better for GPU (less VRAM and much lower GPU loads for same visual quality), however rely so much more heavily on fast single threaded performance on CPU.
 
X3D makes significant difference in some edge case games, for me in particular VRChat, so it may be worth it even if it's boring for all other purposes.

Thats why I like buying the Phenom series, Sandybridge and even FX and mess with it. When I got the 5700g and it was pretty boring so I just set at default and I actually bought the FX 8350 since I already have a motherboard for it. lol

1366 was the last great overclocking platform :respect:

Haswell E and Sandyrbidge were decent. I think i got like 1000mhz out of my 5820k lol imagine that now....
 
So price went up $30, I wonder how many posts we'll see using the words greed and milking it. :sleep:


Not that it matters, if you remember the 7800X3D launch you know how fast the price dropped despite being extremely popular.
 
Seems that you can OC it for at least 200Mhz , thats nice. (source: Gamers Nexus last video)

What really will count is if the 9800X3D will allow for predictable boost clocks, with well-understood offsets. Ideally, it should unlock TDP and voltage, so the only limiter is going to be possibly a clock offset for AVX512. This will make for locking max clocks possible, unlike how it has been quite unpredictable.

Wasn't the voltage range limited after the motherboard shenanigans?
clock offset for AVX512
Unsure if this exists to begin with, as AMD's implementation didn't seem to hit clocks as much as Intel's did, at least if I recall correctly.

Also, about this, isn't it all subjected to silicon lottery? Specially since AMD just programs the things to go as fast as safely possible
 
I highly doubt the current price of the 7800X3D is a sign that the 9800X3D is even more expensive. (Yeah, launch price)

The 7800X3D isn't just more expensive now, it's also out of stock.

If anyone blames scalpers alone, let's not forget that the less popular 7900X3D has gone up in price as well, and is harder to find. All time low was an insane $280, now it's 600.
Good point, but let's not forget concurrence has sth to do with prices too, and in gaming, 9800x3d will probably be the undisputed champ, and when you see the price of arrow lake cpu's and the 7800x3d, there is no reason AMD is gonna price it cheap. Starting price is now confirmed to be 480 dollars, you can be sure if there is a high demand and stocks go fast, the price may rise to a lot more after a time.

There are 2 locked voltages:
VSOC - locked to 1.3v in later BIOS versions only for x3D CPU's (yes, due to CPU's dying), likely due to fragility of the Cache die sitting on top of a 90C CCD die. With Cache die moved underneath the CCD die now, hopefully they can unlock it again.

CPU voltage - locked to 1.2v on all x3D CCD's. Again, with the die repositioning, there's opportunity to unlock this.

Apparently, AMD's implementation of AVX512 is more efficient so not penalized as much in clocks and power, but it must still be consuming more power at the same clocks than other instructions. Honestly, PBO was just AMD's voodoo dance around the TDP and thermal limits. With more things unlocked for overclocking, the voodoo should not be necessary (warranty be damned.)

You're already far away from the TDP limit with the 7800X3D, so with adequate cooling, your only limit is the clock offset. That's why your max clock is locked at 5 GHz single-core and 4.8 all-core.

I don't think VSOC has any effect on the compute die, only the IO.

The 7800X3D runs at around 1 V (core) max.

That much is true. That's why PBO does absolutely nothing on the 7800X3D, because it is already way below TDP limit from the factory.

Nowadays, overclocking makes no sense, but UV is common due to temperatures

If that's the case, that'll be interesting. Let's see if rumours about the reversed cache/CCD are true, and how much they improve on thermals.

Edit: if it was really such a significant improvement, then AMD would have gone with a higher max boost clock, methinks.
These higher clock speeds will probably be left at 9900x3d and 9950 x3d
