AMD Readies 16-core, 12-core, and 8-core Ryzen 7000X3D "Zen 4" Processors
AMD is firing full cylinders to release a new line of Ryzen 7000-series "Zen 4" Socket AM5 desktop processors featuring 3D Vertical Cache, at the earliest. Faced with a significant drop in demand due to the slump in the PC industry, and renewed competition from Intel in the form of its 13th Gen Core "Raptor Lake" processors, the company is looking to launch the Ryzen 7000X3D desktop processors within January 2023, with product unveiling expected at AMD's 2023 International CES event. The 3D Vertical Cache technology had a profound impact on the gaming performance of the older "Zen 3" architecture, bringing it up to levels competitive with those of the 12th Gen Core "Alder Lake" processors, and while gaming performance of the Ryzen 7000 "Zen 4" processors launched till take match or beat "Alder Lake," they fall behind those of the 13th Gen "Raptor Lake," which is exactly what AMD hopes to remedy with the Ryzen 7000X3D series.
In a report, Korean tech publication Quasar Zone states that AMD is planning to release 16-core/32-thread, 12-core/24-thread, and 8-core/16-thread SKUs in the Ryzen 7000X3D series. These would use one or two "Zen 4" chiplets with stacked 3D Vertical Cache memory. A large amount of cache memory operating at the same speed as the on-die L3 cache, is made contiguous with it and stacked on top of the region of the CCD (chiplet) that has the L3 cache, while the region with the CPU cores has structural silicon that conveys heat to the surface. On "Zen 3," the 32 MB on-die cache is appended with 64 MB of stacked cache memory operating at the same speed, giving the processor 96 MB of L3 cache that's uniformly accessible by all CPU cores on the CCD. This large cache memory positively impacts gaming performance on the Ryzen 7 5800X3D in comparison to the 5800X; and a similar uplift is expected for the 7000X3D series over their regular 7000-series counterparts.The naming of these 7000X3D series SKUs is uncertain. It's possible that the 16-core part is called the 7950X3D, and the 12-core part 7900X3D; but the 8-core part may either be called the 7700X3D or 7800X3D. Quasar Zone also posted some theoretical performance projections for the 7950X3D based on the kind of performance uplifts 3DV cache yielded for "Zen 3" in the 5800X3D. According to these, the theoretical 7950X3D would easily match or beat the gaming performance of the Core i9-13900K, which begins to explain why Intel is scampering to launch the faster Core i9-13900KS with a boost frequency of 6.00 GHz or higher. The report also confirms that there won't be a 6-core/12-thread 7600X3D as previously thought.

And the funny thing is that AMD reduced their cpu prices because they can't control the AIBs.
((The mobo manufacturers don't want to sell a mobo that will last 5+ years, so in order to gain as much as possible, they exaggerated a little in their pricing. That's another reason why they love Intel...))
Intel "rumors" on the other hand are usually pretty accruate.
Margins and profit are larger and if they have production capacity at TSMC (just as every company have, except Apple maybe)) they are doing right to focus on the higher tiers.
Intel will stay the value choice for new system builders this and next year.

Been hoping AM4 gets a minor-refresh, and said zen3d.
But yeah, its nice to have a lot of cache however other hardware affects the gaming performance as well. :)
;)
Cyberpunk needs the fastest CPU you can buy. There have been many CPU limited games released recently. Gotham Knights. Marvel's Spiderman. Many more. If you put ray tracing on, you need even more CPU power. Now that the 4090 is here the GPU equation is solved but not the CPU one. Small increases don't cut it. We need a step change. That's the hope of 3Dcache. It allowed a step change in performance for certain games. 20+ percent faster.
The 7700X was just slightly faster than the 12900k (which was only slightly faster than the 5800X for gaming), it didn't do much for gaming like 3Dcache might.
Some of devastating loss were 4c8t i3-10105F beating 8c16t Ryzen 7 2700x, 4c8t i3-12100 beating 8c16t 9900k or in a manner of speaking 6c12t 5600x beating 10c20t i9-10900K. I don't get the idea of 8 core being a bare minimum for playing console port game.
I pity the chums that bought them at original MSRP, only to have them heavily discounted 2 months later, and made obsolete in 6 months by AMD. The price you pay for cutting edge…
Fourth, which game developer said that? Care to share a link?
Fifth, another most CPU demanding game to date...
Trends still continues, 6c12t i7-8700k beating 8c16t Ryzen 7 2700x, or better yet, the same 6c12t Ryzen 5 5600x beating 10c20t Core i9-10900K. Heck even 16c32t Ryzen 9 3950x get a beating left and right.
Please convince me that 8 core is bare minimum for playing newest AAA games.
Still today, A 6 core CPU that have more single thread performance than a 8 core will have same or better gaming performance.
Core aren't slot that Dev fills to make their game. Think about it like a boss with a set of employee. Let say he have 6 incredible employee and another boss have 8 average employee. Both boss run a ghost writer shop and need to produce a 100k word book. (Aka A Frame for gaming)
There are two task, writing the words and at the end editing it. Editing would be done only by 1 staff to make it consistent. (It's the main thread in gaming that control and sync all the other)
Boss A 6 employee can write 1300 words per hours each and review at 5200 words pour hours
Boss B 8 employee can write 1000 words per hours and review at 4000 words per hours
so each boss need to start scheduling the work. He first assign all employee on the first hours into writing words
Boss A would be at 7800 words and Boss B would be at 8000 words.
Then one of the employee would start to review the text for editions,
For boss A, the 5 remaining employee would be done writing 11.8 hours later but they would have to wait for the reviewer. He would be done 19.23 hours later. (for a total time of 20.23 hours)
For boss B, the 7 remaining employee would be done writing 11.5 hours later but the editor would only be done 25 hours later (for a total of 26 hours.)
The fact that the boss B had more "Slot" to put the work into didn't mean they had the job done earlier.
Game work exactly that way. They are way more multithreaded than in the past, but there is still a main thread that is criticial. This is why gaming performance don't scale linearly. (Unlike rendering that have an almost linear scaling since all the job can be done by themselves).
What you need to think is there is by example for each frame x amount of CPU operation per seconds to do in the main thread, and there x amount of cpu operation to be done that can be multithreaded.
A faster core is able to do more operations per second. A really faster core can even do those one after another before the slower 2 core can complete them.
It still the case today, and it will be still the case in the future. Because game have to run a main core as fast as possible then spread the defined amount of load to other core. If faster core finish earlier, they can grab more work before a slower cpu with more core complete it's first job.
Again, in the current gen. 7600x 6 core beat all 8+ core from the previous generation. This is also why the E-core doesn't really help.
One of the gain right now of having a more core CPU is they are binned to run at higher clock. I would like to see what a 7600x running at the same frequency as the 7950x would do. I am pretty sure they would be very close.
