A year after Zen 5's debut, we revisit AMD's Ryzen 9800X3D vs 7800X3D to see if the premium is worth it. With new GPUs and updates, has performance shifted or is the older chip still the smarter buy?
AMD Ryzen 7 7800X3D or 9800X3D, Which Should You Buy?

Good comparison. Must admit I'm surprised, but the newer chip was praised pretty much everywhere.
It's good to know the older chip while not quite as fast is considerably cheaper. I wonder how this pertains to building a PC for gaming with the intention of not upgrading for say, 5 years?
Thanks for this.

Thanks for including the shader compilation, it's a valuable piece of information.
The 7800X3D is still a beast. I think I'll just upgrade to Zen6, 12 cores on a single CCD will be perfect.

In 1440p or 4k the difference will be nearly zero. For gaming, 7800 is simply enough, and 9800 is something I would consider only if it would help me with very specific productivity tasks.
Or if I were to build a new system and the price difference would be minimal. Which is not a case yet. Anyway, I upgrade usually every 3 - 4 generations unless there is a significant change, so still waiting for what AMD will show next year.

LOLNO, Steve, please. Record low it was just before 9800X3D and Failure Lake. Screenshot from one of my local price aggregators, chart is local average prices converted to USD:
Props to all who recognize aggregator

Now correct the title: Which should you buy if you own an Nvidia 5090? Do the same test with anything lower like an RTX 5070Ti or Radeon 9070XT and Ryzen 7600 is enough.

Ok....and it is now available for $360, which is only $19 over its all time low, hence "NEAR record low prices". He didnt say it was record low right now, its NEAR the record low.LOLNO, Steve, please. Record low it was just before 9800X3D and Failure Lake.

If you're going to criticise the writer at least try to understand the argument first......
Please learn how CPU and GPU benchmarks work. This is not an article on "what makes sense in a mid range build".
It's such a simple subject yet so many go slack jawed and drool over their keyboard "duh, what about other GPUs huuuhhhh?" when asked to engage their brain and consider why you would use a 5090 to remove bottlenecks in a CPU review.
Not surprised by the games themselves. I am (a little) surprised the difference is that low on shader compiling. But, it's less a weakness of the 9800X3D and more that the 7800X3D is just that good.
And Moore's Law being a thing of the past.. die shrinks don't automatically reduce power consumption as they did in the past (allowing instead to use the same power consumption but run higher clock speeds.) With modern dies where they've already been shrunk so far, the increased resistance in the wiring as it's shrunk now outweighs the reduction in power consumption from the die shrink itself. And we've had decades to find all the speed tricks in CPU design so no easy speedup from one generation to the next there either. It was hardly every "doubling every 18 months" like Moore's Law said, but it WAS doubling like every 2-3 years until about 2010.. now it's more like doubling every 8-10 years.

Got my 9800X3D for $399.99 at Microcenter a few weeks ago. I'm sure there will be more deals on Black Friday.
Current pirce for 9800X3D is $459.99 and for 7800X3D is $339.99. I'm about to build a new PC and this price difference is noise compared to the total system price. I got a 1200W PS and shopping for a 5090.
I was cash strapped at one point when I built a PC with a GTX 1060 and Ryzen 1600 so I get buying previous gen. My advice, do what I did and get the best mobo you can so that years down the road you can drop in a much faster CPU and GPU. My Taichi X370 went from Ryzen 1600 to 5600 and GTX 1060 to RX 6950 XT. I even upgraded the onboard Wifi/BT chip from Wifi 5/BT 4.2 to Wifi 6/BT 5.0. This mobo is almost 10y old now and still running.

And somehow 3d cache magic works in these tests for 7800 but doesn't for 5800.

Yes, that would be great!
But I doubt it will happen. Seems that the manufactures of these chips actually like a degree of customer confusion.
Is it based on Market Research? No idea, but it will never be VERY simple.
Actually, the title is which you should by not which is theoretically faster when the GPU bottleneck is removed as much as possible.
This. Most people don't understand. A buddy of mine runs a 9800x3D with an 4060TI. He wants to upgrade the GPU next year because of current budget constraints. He bought the system ( with B850 board and 32GB Sweetspot RAM) a couple of months ago. Before that he had a 13600k rig. I kept telling him to just buy a better GPU because the 13600k is perfectly capable for most tasks, but the review hype train is running in his mind - he dreamt of having 40% more FPS, but that stayed a dream. He basically has the same gaming experience as before (ie not looking at FPS counters, just gaming, K/D ratio is the same, Overall experience fells the same - Thats what he said to me). Dude needs to learn the hard way that reviews test CPUs with the 5090 for a reason.
A lot of the mixed use you mention will rely now heavily on the GPU. Where $100 difference may or may not be a tier bump.
That said, it could be the difference between a gen 4 vs 5 mvme, or between 32 and 64 gb of system ram, which you will likely get more improvement from.
With AMD pledging to keep this socket for another two years, it's a no brainer to buy the cheaper option now and only upgrade once the final flagship gaming chip for this generation drops.
Unless you absolutely need to gap that distance, there's no reason to go for it. Myself, I'm on a 3800x and looking to grab whatever x3d I can for my socket, but I'm afraid I've waited too long and stocks have run thin. Don't make that mistake in two years if you're doing what I suggested here.
