AMD Ryzen 9 7900X3D Drops to $409, to Clash with Core i7-14700K
AMD Ryzen 9 7900X3D is the often-ignored middle child of the 7000X3D series that's flanked by the reigning gaming CPU champion, the Ryzen 7 7800X3D; and the company's flagship Ryzen 9 7950X3D, which performs within 5% of the 7800X3D in gaming, but with the added 8 cores shoring up its productivity performance against the Core i9-14900K. Pricing of the 7900X3D dropped to $409 on Amazon, which is a huge departure from its $600 launch price. At this price, the 7900X3D is set up for a direct clash with the Intel Core i7-14700K, which is going for $400, with its iGPU-disabled sibling, the i7-14700KF listed at $392.
The Ryzen 9 7900X3D is is a 12-core/24-thread dual-CCD processor, with its 12 cores spread among two CCDs in a 6+6 configuration. The first of the two CCDs has the 96 MB L3 cache thanks to the 3D Vertical Cache (3D V-cache) technology, while the second is a regular CCD with just the 32 MB on-die L3 cache, but which can sustain higher clock speeds than the 3D V-cache CCD. The similar 16 core 7950X3D flagship can be had for $600, or about $50 higher than the i9-14900K, while the 7800X3D is going for $370.

This is after a nice session of Gaming, including TWWH3, The Gunk, AMS2 and Aliens Fire Team
As you can see all cores were loaded at 100%. Then you can see that all cores have average use at the lowest 1.4% to 11.8%
I for one am happy that those days are gone. Now you can buy a good processor from yesteryear at a bargain.
Price finally reflecting its worth. A 7800X3D is faster in any game, and a normal 7900 (still a 6+6 unfortunately) is faster in everything else.
A 14700K is still a better buy IMO, but at least the price is in line with reality now.
Supposed temperature advantanges of this SKU are irrelevant. All the X3D chips run cool anyway it's not unique to the 7900.
A 12900KS for instance goes for $479 on Newegg down from its $739 launch price. Intel processors always stayed at launch price many years after release in the bulldozer days.
I don't think the Zen 5 launch is imminent or related.
A $40 difference between an eight core and a 12 core, but a $190 difference to the next good CPU that has just four more cores shows how much they want to get rid of these chips though, or how much more in demand the 7800X3D is.
The X3D tech is cool and all but it's still a niche case. Intel did something similar back in the day and then abandoned it for good reasons. You'll also find at the super high end cache is often just disabled completely. In .nix based systems there's a handy command line for doing this as you often have to for reasons.
Clock speed is also meaningless when the CPU with a faster clock is still 5-10% slower in games, which is the point of X3D.
Not many reviewers bothered to look at the 7900X3D.
This is also shown in how late production 5800X3D chips are worse and run hotter than early production ones, since the good bins go to server chips, and just about any die will hit the target frequency anyway since it's so much lower than the standard parts non X3D.
I don't really care how "cool" the 7900X3D is, it's slower than the 7800X3D in the tasks it's designed for, that's what matters.
In fact, it's slightly slower than the 7950X3D since it has 2*6 instead of 2*8 and clocks lower. This would make it the slowest of the three in gaming. Find me a test that shows otherwise if you want to make claims.
As predicted. Slower than 7950X3D, which is slower than 7800X3D (in gaming).
Here's proof.
This was one of the reasons why Intel was kinda hated post 2011-12 or so and NVIDIA in recent years!
