Review AMD Ryzen 7 7800X3D Review: New Gaming Champ Beats Pricier CPUs

Staring at my 7950X3D chip and smiles...I need more cores personally and I have zero problem shutting down a CCD to get max FPS when the need arises which will beat the 7800X3D due to 250mhz higher clocks. Plus if I know a game hates/could care less about the extra cache I can switch CCDs to use the higher clocks. Regardless though this sounds like a great chip. I need to build a rig for my nephew who is graduating high school this year, he might benefit from a 7800X3D if I am nice...otherwise hell just get a 7700X lol.

No real surprise here. For gaming only the 7800x3d is the best choice. That's why I was a little surprised the came out with a 7900 and 7950 variant.

On a side note. When you compare the cost of the 7800x3d + AM5, it's actually only slightly more expensive than upgrading from a 12900k to a 13900ks (700 vs 890 with decent components and 32 GB of DDR 5). If your upgrading from something older than 12th gen Intel or 3000 series AMD it's hard to call the pricing a con in that scenario. Upgrading from either of those in a gaming only environment the prices are pretty close in a 13900k vs 7800x3d when you add all the component prices together.

The reviewer forgot to mention one big con:
Might get fried the second you boot it up the first time...
(if you upgrade from a different CPU and the bios settings are not extremely strickt set for the x3d chip)
https://www.tomshardware.com/news/overclocking-bug-5800x3d
It doesn't burn the chip itself, but the bug does allow you to mess with the voltages, so you can fry it but only if U manually (intentionally) push the voltage to insane levels like Igor did.

As I said, if you forget that you had higher Vcore for your previous CPU you can fry it on the spot.
So, if someone who already bought an AM5 CPU, which could have been purchased, AT MOST, 6 months ago, and has over-volted it, and has decided to swap in a 7800X3D....

That seems like an absurdly niche case. And, for the tiny number of people who are swapping from one AM5 chip to this one, and over-volted, one would think they'd be knowledgeable enough not to be that careless.

This seems like you're really grasping at straws to find a "flaw"/complain about AMD.

I got my eyes on a 7950X, but I understand your perspective. The 7950X3D is one of those things that serves you well if you can afford it.

I guess it is possible, if you had overvolted your previous Ryzen 7000 CPU to 1.3 volts or above, but so far it hasn't been observed by any reviewer. Though why would you change your CPU if you had ryzen 7000 already.

Simple auto settings on a mobo or just PBO should be enough to get into the danger zone.

Also this is a bug that makes the x3d versions look like the normal version to all software.
https://www.techspot.com/news/98154-motherboard-software-bug-makes-easy-accidentally-kill-amd.html
And we already had an AMD driver update that overclocked CPUs without the consent of users, it's not thaaaat far fetched.

AMD is the efficiency king, great upgrade to the 5800x3d, unfortunate that they led with the 7950x3d/7900x3d. Obviously it was better for their bottom line (increased profit/revenue for those who could not wait). The 13900ks is simply not competitive if going Intel best bet is the 13700k for gaming and save that money, if more is needed in terms of productivity then go for the 13900k.

So as it stands, Intel is barely ahead in productivity and still commends a decent lead in single threaded performance(legacy applications). AMD owns gaming thanks to v-cache & is the winner by a mile in terms of efficiency. This is going to be really interesting in the Laptop space, Too bad AMD has a really bad naming scheme that requires a decoder wheel to understand what zen generation is being utilized.

I'm building a new ITX rig and I'm really glad that I decided to wait to see what the 7800X3D was going to bring to the table and now I think that's going to be the CPU I put in this rig. Now to find a motherboard that supports it out of the box without a BIOS update.

We seem to be in a similar position, so I'd be interested which motherboard you end up settling on. If you don't mind me asking, what's driving your preference for support out of the box? Convenience, reliability, performance? Or something else?

For me it's more of a preference thing. It's more that the AMD processor swap / BIOS update process can be really intimidating (I've done it before on previous rigs I've had), and there's always a chance something could go horribly wrong. I'd personally rather take fewer chances and have everything work right out of the box, then have to assemble the entire rig, then disassemble it, just to swap the CPU. I also don't have a previous AM5 CPU to work with, and I'm buying all new hardware for this rig, so that would further complicate things.

Best gaming chip if works :)

I was going to disagree with you, but that's a fair point. The BIOS really should reset VCore to default when you change the CPU. If it doesn't, that's a potential serious issue. It's best that people are aware of it.

That said, any fried CPUs when you're changing VCore are the user's fault.
