New rumors concerning AMD’s Ryzen 7000 V-Cache CPU that includes the Zen 4 “3D” structure have been dropped at us by Moore’s Law is Dead. The rumors embrace some early architectural particulars, efficiency benchmarks, and attainable launch dates although that is only a rumor which must be taken with a slight pinch of salt.

AMD Ryzen 7000 With Zen 4 X3D Cores Rumored To Get 2nd Gen V-Cache, Possible Performance Benchmarks & Launch Dates Revealed

Before we begin with the rumored particulars, we now have to make it clear that AMD themselves acknowledged that Ryzen 7000 CPUs with 3D V-Cache expertise will seem later this 12 months throughout FAD 2022. Following is their quote:

Ryzen 7 5800X3D is the perfect gaming processor out there bar none. We are happy with what V-Cache expertise is doing for us and we’re gonna function this in Ryzen 7000 collection later this 12 months and sooner or later technology.

So with that mentioned, let’s get on with the rumors. According to Moore’s Law is Dead, the AMD Ryzen 7000 V-Cache elements are anticipated to make the most of a TSMC 7nm or 6nm course of node for the V-Cache. The CPU cores will probably be manufactured on the TSMC 5nm course of node like the usual Zen 4 cores however the V-Cache that stacks on high of these cores are mentioned to make the most of a distinct node. The rumors additionally state that Zen 4’s V-Cache would be the similar capability as Zen 3’s V-Cache, at 64 MB per stack however the expertise is claimed to be superior to 2nd Gen which makes it simpler to deliver the market with some inner benefits reminiscent of greater bandwidth.

One factor that the earlier technology V-Cache CPU, the Ryzen 7 5800X3D, lacked was help for overclocking, and to preserve energy draw (voltages), it got here down-clocked versus the non-V-Cache elements. The Zen 4 V-Cache CPUs are mentioned to ease down on these voltage restrictions and whereas their clock speeds are anticipated to be decrease than the usual non-V-Cache elements, they are going to run at a lot greater speeds and the clock disparity won’t be as important this time round.

Moving over to the alleged benchmarks, the rumor from Moore’s Law is Dead factors out a chart that compares Zen 3 with Zen 3 V-Cache, Zen 4, & Zen 4 V-Cache CPUs. The Zen 3 CPUs are based mostly on the ultimate silicon whereas the Zen 4 CPUs are based mostly on the early A0 silicon.

The chart factors out 4 particular benchmarks although it isn’t talked about what these workloads are nor the precise config however contemplating X3D elements show a serious efficiency profit, it’s possible that these are video games and never precise workloads. All CPUs examined right here have been examined on the identical energy stage and additionally it is talked about that the Zen 4 chips weren’t working at their remaining increase clocks which we all know are going to be surprisingly excessive within the 5.5 GHz+ vary (5.7 GHz on the flagship).

AMD Ryzen 7000 “Zen 4 3D” CPU Rumors: 2nd Gen V-Cache, Early Zen 4 & Zen 4 V-Cache Performance Figures

In phrases of efficiency, the allegedly inner AMD doc reveals that whereas Zen 3 V-Cache supplied a 10-15% efficiency increase over commonplace Zen 3 Ryzen 5000 CPUs, the Zen 4 V-Cache CPUs provide as much as a 30% efficiency increase over the usual Zen 4 Ryzen 7000 CPUs.

Now this appears to be like important certainly however as soon as once more, the Zen 4 being constrained all the way down to Zen 3’s TDP (170W vs 105W) is a serious drop and might have an effect on the efficiency considerably. Since the V-Cache elements are already tuned for lower-voltage operation and it is the V-Cache and never the frequency doing the primary lifting job in video games, this consequence was anticipated. So general, we would see a 10-15% improve versus commonplace Zen 4 CPUs for the V-cache elements with the ultimate silicon, remaining clocks, and remaining TDP.

Lastly, Moore’s Law is Dead studies that Zen 4 3D V-cache CPUs have been deliberate for 1H of 2023 however they may be launching a bit earlier now that Raptor Lake is within the play. The rumor states that two chips, the Ryzen 9 7950X3D and the Ryzen 7 7800X3D are anticipated to be a part of the Ryzen 7000 V-Cache lineup and AMD might do a paper launch by the top of This fall 2022. But we now have to return to AMD’s unique quote from FAD 2022 which reveals that the corporate certainly plans or deliberate to supply Zen 4 V-Cache later this 12 months until they modified their schedule in any other case. There have been just a few rumors previous to FAD 2022 that the corporate may need delayed V-Cache elements to 2023 however after the keynote, we dismissed these rumors.

So it appears to be like like Intel’s Raptor Lake CPUs will probably be challenged by AMD from each fronts within the type of Ryzen 7000 & Ryzen 7000 X3D V-Cache CPUs. The Zen 4 elements are at present going through a brief delay to late September because of BIOS points however the firm plans on doing a full unveiling later this month on twenty ninth August.
