The Ryzen 9 7950X3D, 7900X3D, and Ryzen 7 7800X3D CPUs will go on sale at the specified time and price, according to an official announcement from AMD.
AMD Ryzen 7000 X3D CPUs with 3D V-Cache Start At $449 US, Launching On 28th February
The second generation of consumer V-Cache components with stacked cache is the AMD Ryzen 7000 3D V-Cache CPUs. One 3D V-Cache SKU was available in the Zen 3 lineup, but the Zen 4 lineup will offer three SKUs at wildly varying prices.
AMD Ryzen 9 7950X3D – 16 Cores With 144 MB Cache
The AMD Ryzen 9 7950X3D, the first 16-core CPU to support 3D V-Cache technology, is at the top of the list and will serve as its flagship. A total of 32 threads, 144 MB of cache (64 MB CCD, 64 MB V-Cache, and 16 MB L2), and a TDP of 120W are all features of the chip. The chip is rated for base clocks of 4.2 GHz, which is 300 MHz slower than the standard 7950X, but boost clocks are rated for the same at 5.7 GHz. This ought to provide us with some insight into why the TDP is 50W lower than the non-3D part.
By placing the SRAM cache on a single CCD rather than both CCDs, AMD is structuring the 3D V-Cache on the Ryzen 9 X3D parts. In this manner, AMD can maintain the secondary die to take advantage of the higher clock speeds while still maximizing performance in gaming through a single CCD (1T). This means that, unlike the previous generation, there should be a balance between the performance of single- and multi-threaded applications. The cache die needs to be optimized more because this chip is primarily intended for gaming. It will be interesting to see how things turn out in the retail units as they are finalized and how much tuning AMD allows for the new parts.
At launch, the AMD Ryzen 9 7950X3D will cost $699 US, which is the same MSRP as the original 7950X prior to being discounted to $599 US. The CPU would be accessible on February 28.
AMD Ryzen 9 7900X3D – 12 Cores With 140 MB Cache
The AMD Ryzen 9 7900X3D, which has 12 cores and 24 threads, is the second processor. This configuration also uses two CCDs, one of which has the V-Cache enabled and the other does not. The chip has 140 MB of cache in total (64 MB CCD, 64 MB V-Cache, and 12 MB L2). The base clock is rated at 4.4 GHz, 200 MHz less than the Non-3D SKU, and the boost clock stays at 5.6 GHz. Additionally, the CPU has a TDP of 120W.
On February 28, the AMD Ryzen 9 7950X3D will be released alongside it. Both processors will be priced at $599 US.
AMD Ryzen 7 7800X3D – Replacing The 5800X3D As the New Gaming Champ!
The Ryzen 7 7800X3D is the model that succeeds the Ryzen 7 5800X3D. With 8 cores, 16 threads, and the same 104 MB of cache (32 MB CCD, 64 MB V-Cache, and 8 MB L2), this CPU will be the best option for gamers. The CPU has a boost clock of 5.0 GHz, which is 400 MHz slower than the Ryzen 7 7700X, and a base clock of about 4 GHz, which could end up being at least 500 MHz slower than the Ryzen 7 7700X.
The AMD Ryzen 7 7800X3D, which will be available on April 6 for $449 US, is the last option.

We can see that AMD is effectively manage the cache die and the clocks in this situation according to what we predicted. But besides the Ryzen 7 7800X3D’s lower clock speeds than AMD’s Ryzen 7 7700X, which has a TDP of 105W, the 120W TDP is still maintained. This indicates that AMD is strongly optimizing those base/boost clocks on the Ryzen 9 parts to meet the 120W target as the cache requires that additional TDP limit. Further testing will be interesting to observe these clock variations between the dual Ryzen 9 CCD SKUs.
When it comes to performance, AMD claims that the Ryzen 7 7800X3D overtakes the Ryzen 7 5800X3D by a whopping 30%. AMD isn’t disclosing any information about the test settings or combinations that have been used, and the games used are hand-picked, but if these results are accurate, we might see the Ryzen 7 7800X3D become equally popular as the Ryzen 7 5800X3D in the retail market.
As previously mentioned, AMD will support PBO and Curve Optimizer on its Ryzen 7000 X3D CPUs, and we also discussed how the TjMax numbers for the new chips are this time around a little on the conservative side. We will need to wait until the last evaluations, which should arrive in a few weeks, in order to learn more. In order to completely enable Ryzen 7000 X3D CPU endorse on established AM5 motherboards, AMD has also noted that consumers will be required to update their chipset drivers and BIOS; however, we also know that a few motherboards will soon be released that come with out-of-the-box X3D support.
