AMD today announced a suite of new CPUs based on the company’s latest Zen4 architecture. Chief among these are the new 3D V-Cache desktop parts and a range of new mobile processors.
On the desktop side, we have three new 3D V-Cache models as AMD expands its lineup to include dual CCX models as well. This includes the 8-core Ryzen 7 7800X3D, 12-core Ryzen 9 7900X3D, and 16-core Ryzen 9 7950X3D.
The 7950X3D has the same 16MB L2 cache as the 7950X, but the L3 cache has been increased to 128MB for a total cache of 144MB. The 7900X3D also gets 128MB of L3 cache, bringing the total to 140MB. The most important part is that both of these models have the same clock rates as their non-3D V-Cache variants.
The 7800X3D has a more modest upgrade that’s more in line with the 5800X3D. Compared to the 7700X, the 7800X3D has 8GB L2 cache but the L3 cache has been increased to 96MB, same as on the 5800X3D. Also, like the 5800X3D, the 7800X3D has reduced clock speeds compared to the 7700X, reducing the maximum boost from 5.4GHz to 5.0GHz.
It is worth noting that while the 7950X3D and 7900X3D have double the L1 and L2 cache of the 7800X3D due to having two CCX drives, the L3 cache is not doubled, suggesting that all of the extra 3D V-Cache is dedicated to only one of their CCX extension. This may explain why the 7700X3D has lower clock speeds, otherwise it would perform very similarly to the more expensive 3D V-Cache models in gaming.
AMD also announced new affordable non-X models in the Ryzen 7000 series for desktops. This includes Ryzen 5 7600, Ryzen 7 7700 and Ryzen 9 7900. The 7900 is particularly interesting as it is the first time that a non-X Ryzen 9 part will be sold directly to regular buyers and not just OEMs.
These new parts have lower clock speeds and lower power limits of 65W, with the 7600 and 7900 getting a 200 MHz reduction in boost clocks and the 7700 getting a 100 MHz reduction over their X variants. The The 7900 and 7700 also come with AMD Wraith Prism coolers in the box, while the 7600 comes with the Wraith Stealth.
Moving forward, AMD also announced its new Ryzen 7000 series of mobile processors. This includes the top-of-the-line Ryzen 7045 “Dragon Range” series for gaming and creator laptops and the Ryzen 7040 “Phoenix” series, for ultra-thin flagship laptops, both based on the Zen4 architecture. These chips also feature a dedicated AI engine, a first for an x86-based processor.
Then there’s the Zen3+-based Ryzen 7035 “Rembrandt-R” series for premium thin-and-light laptops and the Zen3-based Ryzen 7030 “Barcelo-R” series for mainstream thin-and-light laptops. Finally, the Ryzen 7020 ‘Mendocino’ series is for entry-level machines and based on the older Zen2 architecture.
All combined there are eighteen models in the Ryzen 7000 for mobile, which is exactly the level of confusion you’d expect from any laptop-related hardware announcement.
AMD also announced the Radeon RX 7000 series graphics for laptops based on the new RDNA 3 architecture. There are four models, the more powerful RX 7600M XT and RX 7600M for powerful gaming laptops and two lower power variants RX 7700S and RX 7600S for thin and light laptops. The 7600M XT and 7700S have 32 compute units while the remaining two have 28. All have 8GB of GDDR6 memory and 32MB of Infinity Cache. The main difference is that the 7000S series has lower clock speeds for lower power consumption.
