Poll: Ryzen 7950X3D, 7900X3D, 7800X3D

Will you be purchasing the 7800X3D on the 6th?

I only in the last week got a 7800X3D as a temporary chip until my 9800x3d arrives. So I am already 2 years late to the party. Maybe it's "New toy syndrome" But I almost forgotten about AMD. I use to be on the 5950x which I loved then migrated to the 12900k when it was released and then stuck with intel.

So you can imagine when I see my cpu at full load is 85w how floored I am. On the Intel platform I have never seen less than 250w at full load. Then I read various forums and peeps were like the 7800x3d is a beast but tricky to cool. I have found at least in my use case it to be anything but. For the temp setup I am using artic cooling 3 420mm and a contact frame.

I haven't used AMD in at least over 3 years but yesterday I just jumped in -35 on PBO limited it to 80W ran Cb23 19200 multi core. Then I jumped into my fave benchmarking programs like the Finalfantasy graphics benchmarks. Ran Dawntrail and endwalker and I am not gonna lie. I expected a small increase but what I got was way more than I expected. This using 5200mhz Cas 40 ram that I had lying about for backup spares.

So on intel setup whether it was 12900k, 13900k 0r 14900k using a 4090 I have never seen the Maximum preset at 4k above 26k depending on what chip I used I get between 24-26k. Last night I got 32k. Honestly I expected 27k maybe slightly higher. I was getting similar speed increases across other various Final fantasy benchmarks. Funnily enough I haven't actually gamed on this Am5 setup as for some reason it won;t let me connect to wifi no matter what. I have installed windows 10 about 3 times. Windows 11 2 times and it still won't let me connect to the internet. Not my phone as a mobile hotspot so I might have to RMA this board.

I also think that AMD users should count their lucky stars. WHile this CPU remains a hot cpu, it really isn't compared to the intels. It's not even close.
When you bench something like a 12900, 13900k and 14900k on something as benign as CB23 and see the cpu is drawing 300w, 350w and 400W respectively if you don't control it via bios you don't really know the true nature of the dark side.

My original plan was to use this 7800x3d as a temporary chip just so I could flash the board and get use to being back on the AMD platform then sell it when my 9800x3D arrives. But while I have only had limited usage of this setup due to my connection issues I have loved every minute of it. But I just may have to keep it to build another setup.

And I have found it eerily cool to run. So even though the cpu die average temps says it's 35c. When I check the actual individual cores are at 20-21c.
I have been pleasantly suprised by this chip and can't wait for the 9800x3d to arrive.

The 7800X3D is an incredible chip and I was blown away by the performance coming from a 10900K which had way more cores and threads and overclocked too! Temps are usually for me around 43C in windows and 66 - 70C in games so deffo not a hot chip either. The ONLY time the heat skyrockets to around 80C is when a game does a shaders compress. So around a few mins of this

I can’t comment on gaming as I haven’t used it for that yet. My idle temp is 35 die average according to hwinfo. The most I have ever seen is 77 die average in cb23 10 minute multi core test. the actual cores were 70-71

probably not if gaming is your main use. 7900 has 12 cores over 2 CCD so technically for gaming the 8 core over 1 CCD in the 7800x3d would be better, at least that's my takeaway from what I have been reading in this thread.

wow, i would not have thought this,

This website agrees with you both

AMD Ryzen 7800X3D vs. 7900X3D vs. 7950X3D

With recent price changes, the Ryzen 7800X3D can now be had for as little as $370, the 7900X3D is just $20 more, and the 7950X3D is down...

im quite shocked to see the 7800X3D on par with the 7950X3D

I think game bar is part of windows as standard. It is essential for the multi CCD X3D chips to ensure core parking is working. Just make sure you don’t disable the service. To be fair MS are quick to update it with game profiles, so it’s rare you need to update it manually.

It is also essential to ensure balanced power profile is selected in the windows power settings. Don’t select max power or core parking stops working. You are essentially telling windows to keep all cores active always.

Keep your AMD chipset drivers updated from the official AMD drivers site as well.

Core parking requires three things (that I can see)

1. XBOX Game Bar running (it does by default) and updated
2. AMD chipset drivers installed and regularly updated
3. Balanced power profile set in Windows

I've just swapped out my 7700X for a 7900X3D and my Call of Duty average FPS has actually dropped according to the onboard benchmark.

It's the GPU frames that have dropped though rather than the CPU

My before and after numbers are below this is at 1440P max settings with no frame gen or upscaling.

CPU
Avg 188 FPS - 229 FPS
Low 5th - 148 FPS - 174 FPS
Low 1st - 132 FPS - 153 FPS
Bottleneck 29% - 4%

GPU
Avg 168 FPS - 157 FPS
Low 5th - 136 FPS - 174 FPS
Low 1st - 131 FPS - 153 FPS
Bottleneck 71% - 96%

Global average
161 FPS Before
158 FPS After

I'm a bit confused by the numbers. Why has the better CPU pulled the GPU numbers down? Is the benchmark estimating what the GPU could achieve but now it's actually getting the CPU horsepower it turns out it can't?

Did you update the AMD chipset drivers and is the 3D V cache service running\installed?

I've updated the BIOS and chipset drivers, I've checked game bar is working. My CPU performance has definitely improved. It's strange.

I've checked against the link you posted and I've done all that thanks.

Like I say the CPU performance has increased but the GPU has decreased.

Made me laugh, I think I'm in the same boat. Last AMD chip I had was a X64 Athlon. That must be 20 years.

Ive just bought a 7800x3d/4080 Super. Don't care to wait it out till the 5K cards or pre order a 9800x3d I'd have to deal with 5k card pricing and scalpers for months probably. This should do for half a decade.

You may have to reinstall windows, Jay2cents did a video of this topic. Windows get confused as you've gone from a 1 CCD to 2 CCD chip. It will be spreading the threads over both and not getting the vcache improvements.
 
AMD themselves recommended to reviewers to reinstall windows when the chips came out. if you want core parking to work correctly make sure windows is in balanced power mode. if core parking is still playing up reinstall the os its down to the chipset drivers.
 
Hi there can anyone help me please.
Purchased the 7950x3d and am5 gigabyte motherboard.
Loaded up hwinfo 64 and looking at volts there is loads of volts to look out for.
Been keeping my eye on Cpu vddr Soc Voltage sv13 TFN
i know to keep under 1.3 volts but further down Cpu Vcore soc can rise about 1.3 volts.
which volts should i keep watching only.
there is a Core Vid as well.

Anyone running 4 sticks of RAM at 6000 cl30 without issue?
Click to expand...
I don't have these chips (only the 7950x not a x3D) and from all accounts, no one thus far has got any of the 7000 chips to run 4 sticks of RAM at anything close to 6000 CL30. The best I remember reading has been 5200 odd, but unsure on the latency number. With most hitting 4000-4800 region with extreme tweaking. And others being forced to stick at 3600 for stability.

Supposedly with the newer X870E boards (with 8+ planes) it might be possible to do so, but unsure if the reviewer meant that with the older 7000 series chips in these boards or the newer 9000 series chips on these motherboards.
