AMD announces new Ryzen 7000 desktop and mobile CPUs

05 January 2023

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 as well as a range of new mobile processors.

On the desktop side, we have three new 3D V-Cache models as AMD expands its range to include the dual CCX models as well. This includes the 8-core Ryzen 7 7800X3D, the 12-core Ryzen 9 7900X3D, and the 16-core Ryzen 9 7950X3D.

The 7950X3D has the same 16MB L2 cache as the 7950X but the L3 cache has been bumped up to 128MB for a total cache of 144MB. The 7900X3D also gets 128MB of L3 cache, taking its total to 140MB. The most important part is that both these models have the same clock frequencies as their non 3D V-Cache variants.

The 7800X3D has a more modest upgrade that is more in line with the 5800X3D. Compared to the 7700X, the 7800X3D has the 8MB 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, dropping max boost from 5.4GHz to 5.0GHz.

It's worth noting that while the 7950X3D and the 7900X3D have double the L1 and L2 cache of the 7800X3D since they have two CCX units, the L3 cache isn't doubled, suggesting all the extra 3D V-Cache is dedicated to only one of their CCX. This may explain why the 7800X3D has lower clock speeds, as otherwise it would perform very similar to the more expensive 3D V-Cache models in games.

AMD also announced new affordable non-X models in the Ryzen 7000 series for desktop. This include the Ryzen 5 7600, the Ryzen 7 7700, and the Ryzen 9 7900. The 7900 is particularly interesting as it's the first time 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 65W power limits, with the 7600 and the 7900 getting a 200MHz reduction in boost clocks and the 7700 getting a 100MHz reduction compared to their X variants. The 7900 and the 7700 also come with AMD Wraith Prism coolers in the box while the 7600 comes with the Wraith Stealth.

Moving on, 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 flagship ultrathin laptops, both of which are based on the Zen4 architecture. These chips also feature a dedicated AI engine, a first for an x86 based processor.

Then there are the Ryzen 7035 'Rembrandt-R' series based on Zen3+ for premium thin and light laptops and the Ryzen 7030 'Barcelo-R' series based on Zen3 for mainstream thin and light laptops. Lastly, the Ryzen 7020 'Mendocino' series is for entry-level machines and based on the older Zen2 architecture.

All put together there are eighteen models in the Ryzen 7000 for mobile, which is exactly the level of confusing you expect from any laptop related hardware announcement.

AMD also announced Radeon RX 7000 series graphics for laptops based on the new RDNA 3 architecture. There are four models, the higher power RX 7600M XT and the RX 7600M for powerful gaming laptops and two low powered variants RX 7700S and the RX 7600S for thin and light laptops. The 7600M XT and the 7700S have 32 compute units while the remaining two have 28. All have 8GB of GDDR6 memory and 32MB Infinity Cache. The major difference is that the 7000S series have lower clock speeds for reduced power consumption.
