AMD’s Zen 3 CPUs were groundbreaking when they were released, but it’s time to upgrade. The chip maker has announced that it will modernize its existing CPUs with a new 3D V-cache stacking technology, which could make a big difference for gamers.
This post has been updated since its original publication.
AMD’s Zen 3 5800X3D CPU: Expected performance
With no further design changes, the updated 5900X ran Course 5 12 percent faster at 1080p – despite no further adjustment of the power consumption and a fixed frequency between the two CPUs. According to the AMD presentation, other games also benefited from the technology Monster Hunter world a 25 percent improvement over the new design. (A footnote in AMD’s presentation added that the updated Zen 3 CPU was 15 percent faster on average in 32 separate PC games, despite some titles like League of Legends saw only a small increase in performance.)
The new 3D V-Cache technology was introduced by AMD’s CEO Dr. Lisa Su announced at Computex 2021. In the presentation, AMD presented a demo presentation in which a 5900X of the current generation was running Gears of War 5 Comparison with a prototype 5900X built with the new 3D V-Cache technology.
At CES 2022, AMD announced the official naming conventions for the new chips: X3D. The average increase in performance of the X3D chips across a range of games was 15 percent, although some titles – such as Guard dogs: Legion and Far Cry 6, saw increases of 36 percent and 24 percent compared to a regular Ryzen 5900X.
Compared to the i9-12900K, AMD showed slides claiming the 5800X3D was 17 percent faster than Intel’s fastest Alder Lake CPU in Final Fantasy XIV and 8 percent faster in Shadow of the Tomb Raider. Interestingly, the refreshed 5800X3D could only get parity with the 12900K in. reach Course 5, and Intel’s CPU was 2 percent faster in CS: GO.
But what exactly is 3D V-Cache?
To understand the benefits of V-Cache, we need to look at how the current Ryzen Zen 3 CPUs actually work. If you were to disassemble a Ryzen 5000 series CPU today, you would see a core complex (CCD) underneath.
Each CCD can be attached to a 32MB L3 cache. If you’re using a 5900X or 5950X in your gaming PC, these CPUs have two separate CCDs, so they have a total of 64MB of L3 cache.
L3 cache can be very useful for gaming, often more than more cores or threads. While more of anything is generally a good thing when it comes to game performance, an analysis by Techspot found that more L3 cache can often be more beneficial, provided the game isn’t fully GPU-bound.
“If you’re upgrading from a Core i7-8700K – which is essentially a Core i5-10600K – to the Core i7-10700K or slightly faster and you see an increase in performance, it’s likely not because of the additional cores. but rather the additional cache “, Techspot completed.
To increase the amount of L3 cache on their CPUs, AMD invented 3D V cache technology. The design vertically stacks an additional 64MB of L3 cache on each CCD, making a maximum of 192MB of L3 cache possible. That’s more than double what the current Ryzen chips can offer, and by connecting the new cache directly to the complexes and adding structural silicon, the updated chips look identical to their Zen 3 counterparts, according to AMD.
“Just the existence of [3D V-Cache] is a generation leap in performance “, Robert Hallock, AMD’s Director of Technical Marketing, said in an interview in October.
Do I need to update my PC to update Zen 3?
No. AMD has confirmed that the updated Zen 3 chips are compatible with their existing AM4 platform. So today, if you have a motherboard that is already running a Ryzen 3000 series CPU or a Ryzen 5000 series CPU, you can purchase the updated Zen 3 CPUs as soon as they become available.
AMD’s refreshed Zen 3 5800X3D CPU: release date, price
Hallock confirmed that AMD did the Zen 3 will be updated “early 2022”, and AMD CEO Lisa Su confirmed that the CPUs would hit the market in the spring (or fall for those in the southern hemisphere). Meanwhile, only the 5800X3D was announced AMD’s CES reveal, However.
Dr. Su also confirmed that AMD’s Rembrandt CPUs – also known as their Ryzen 6000 series, which will compete with Intel and Apple in the laptop market – will hit the market in February, with the Ryzen 7000 desktop CPUs and the AM5 motherboard platform will follow in the second half of the year.
AMD has not officially announced a price for the 5800X3D Zen 3 refresh, although this is only expected shortly before the chip is launched. The 5950X is currently available at retail outlets for around $ 799, € 749.99 or $ 999 AUD. AMD’s approach to previous generations has been to devalue the older CPUs while its newer products assume the same price. With the Zen 4 coming, it wouldn’t be a surprise if AMD took the same approach here.
