So glad I went with the 5800X3D which I got at a still in Jan for 300 (US). I was on the fence about paying the first gen tax and after finally getting a new GPU at a good price. I had a Sapphire Nitro RX 480 and 3600 non-x, I got a new 165Hz 3440x1440p monitor for Christmas and that setup was not liking the monitor. Was basically playing everything on low setting just to see 80ish fps in games. found a deal on a Gigabyte OC 6750 xt for 330 (US). Popped it in and was only holding 100ish fps on high setting, so I started looking at new MOBO and CPU. I really didn't like the taste of having to also drop on new DDR5 at the price they were at the end of last year. So when I found a deal at like 4 in the morning at Walmart I pulled the trigger. Man did that help I now see 150-160 fps in most the games I play on high settings. And after seeing were the 5800X3D (God it gets tiring typing that names lol) landed on these charts I'm happy with my choose for the next 2-3 years, I mite pick up a new GPU when I see what AMD has for the 8000 series. I also got lucky on my 5800X3D in the lottery as it runs prefect at 1 volt flat and never really see about 45 C on a 360 AIO, highest I could get it was 62 C on Aida64 test for 2 hours. Now the gigabyte OC 6750XT not so much it run hot as hell most the time, thanks to its cooler being a bad design, she's always at 65-85 c full maxed out.

AMD X3D chips still not ready imo. it's clear the large cache makes it less memory dependent thus it over comes being behind intel's memory controller, but it still lacks in frequency, nice way around it, but still not really performing to the full potential of what it could be. I see now why they didn't put the 5800X3D on the zen3+ architecture(this massively increased performance per watt, and with the 5800X3D having to give up some of that ppt to the vcache this would of done a lot for the chip) because it would basically make the 7000 series look worthless at that point. once AMD X3D chips reach the point where the memory controller and the clock speeds can remain high they'll have a clear winner on their hands. It's also interesting to see what a 16c 32t chip with both chiplets having stacked cache on them would do.

The 7950X3D makes sense only as the most 'over the top' option. If you pair this with anything but an RTX 4090 (or ti when it comes out), stare at yourself in the mirror until you figure out what you've done.
The 7900X3D is actually for nobody.
It sounds like the 7800X3D will be the only 'sensible' 3D version, if even that.
The 5800X3D was a bloody amazing send-off for AM4 and gamers will have years of enjoyment upgrading their 2600 to 5800X3D when lack of cache will start to hurt other AM4 CPUs in the future. I hope they drop the X900X3D skew next line-up and have the sensible gaming oriented 8800X3D (or even just a 8700X3D) and the baller 8950X3D

Impressive seems like 3D cache stacking is the future NOT Intels overcomplicated P core and E core thing they got going
If all CCDs had 3D cache these CPUs will have universal performance under all circumstances and operating systems
I assume that will be the case in the future.
The real metric that matters with CPUs is efficiency. Whatever tech makes a CPU more efficient is important and if that means putting a gigabyte of Cache on a CPU in the future so be it.
A 7800X3D in a year or so and a new board will then probably be my upgrade if financially feasible and last me 5 years in active use I recon.
Imagine a 7600X3D for like 150 ...

nominal efficiency is not efficiency chart....the efficency is NOT linea so you are NOT measruing efficency but nominal efficency at peak performance...if you want to emasure efficency you have to lock the performance to a set amount and measure the power needed to reach this goal OR lock the power consumption and measure performance...THAT would be efficiency....ITs litterly the same as IPS you CAN not measure it if you dont hold one value constant...diffrence performance at different wattage of different cpus gives you ZERO constant this value only ranks the default settings by some abitrary set workload.....

I feel like AMD is not sure about the value of their own stuff. After the massive failure of the 7900x and 7600x (which made the release of the non X versions) All of these are 50-100 us too expensive in my opinion.
If farcry 6 was supposed to be the highlight, It only makes the 13600k look like an amazing value.
As for SOTR, performance is amazing. But so was the 5800x3d. It's also a single player game running at more than 250 fps.
So it seems to be a hit or miss situation. If you game is like SOTR, your cpu is king. If not, you wasted money. Might as well just wait and get the 7800x3d

I ended up going with the 7900X3D because the 7950X3D went out of stock everywhere within 30 minutes of release and I really couldn't afford to wait since I'm moving to another state this month and need my computer for work.
Coming from a 5600X, it's a massive improvement in productivity and gaming, but it's definitely bitter sweet though since I knew about the 6 cores only having access to the extra cache and it sure as hell isn't great from a value perspective, but that's the early adopter tax for ya.
Great review as always!

You said it on your previous video and you said it again here, no benefit in our wide array of workstation suite . Your workstation suite mostly only tests one thing, video production! There are many, many workstation tasks that benefit hugely from these, some of them very common, there's more to workstations than A/V work. Some examples: Almost any science/engineering simulation (think modeling), cloud dev (VMs eat working memory alive at all layers), and some tasks in data engineering (duh I guess) come to mind immediately.

Here in Europe this SKU costs 685 which will buy you an 13900K while saving 50 . Rly a nobrainer to go for Intel here. Not 100% sure why AMD has chosen to lauch 3D v-cache variants of their higher core count consumer lineup too. As this cache only improves gaming performance there is no reason to bring sth beyond the 7800X3D. Got the feeling AMD is gonna burn a lot of money with the 12 and 16 core variants. After all, implementing 3D v-cache is not cheap, and I expect that margins for AMD are higher with non 3D variants.

Ouch really DOA here, intel seems far more consistent and balanced in gaming overall here not so volatile. AMD really seems like they are just giving us the minimum that they can to seem somewhat more competitive against intel to make the most possible money for their shareholders. I really wish they would stop beating around the bush and hit something out of the park here so I can build an AMD system again, for now I'll be sticking with the 13900K. very, very disappointed here.

Had a feeling that this would be the case of 7900x3d the price/performance ratio isn't the greatest especially once you consider the market it's surrounded by right now. Once you start comparing everything it's going against especially within AMD's own market it makes it hard to start trying to justify that Price/Fps difference. But all that being said it's still pretty great that both sides are competing for that Best Gaming CPU and making better products for the consumers.

What a fall from grace for AMD. After the 5900X (still in my current rig) I was hoping that history would repeat itself for the X900 series once again after the 5900x was such a killer CPU. I'm still super satisfied with my current rig and will wait to see what Zen 5 has to offer and for DDR5 prices to normalize before upgrading in the future. This is definitely the fastest turn around time I've ever seen for a review and it's always appreciated.

Why is everybody talking about the 7800X3D having a frequency problem. The 3D-cached enabled CCD on the 7900X3D and 7950X3 are also running at a lower frequency. It only looks good on the spreadsheet, because it shows the frequency of the CCD that doesn't have the 3D-cache. Hardware unboxed showed that turning the non 3D-cache CCD completely off in the bios, makes the 7950X3D even faster, so the higher clocked non 3D-cache CCD has no influence!?

All your performance charts would benefit from significant culling, especially for testing a specific SKU like this.
Zen 2 has no place here, Zen 3 and LGA1700 should be represented by their top-end CPU, respectively. All of that would quickly reduce clutter by 50% and make the new information presented easier to gather visually. Also, there is value in comparing this 3D CPU with its non-3D brother across all tests in a single chart.

The 7800X3D should be a much better balanced design with the single L3 cache available to all 8 physical cores.
I am very interested to see the performance of 7800X3D with 120W power usage.
I have not been impreseed with the heat generated by the latest other AMD and Intel processiors.
I hope the 7800X3D proves to be a better design direction.
Does anyone agree with my thoughts ?
