While the clock speeds for AMD’s (AMD) – Get Report latest desktop CPUs are similar to those of their predecessors, it promises architectural changes will deliver major performance gains.
And that in turn has major implications not only for AMD’s desktop offerings, but also upcoming notebook and server CPU refreshes.
As expected, AMD unveiled its anticipated Ryzen 5000 desktop CPU line — the first products to rely on its next-gen, Zen 3, CPU core microarchitecture — during a Thursday event that was live-streamed on its website.
AMD’s Ryzen 5000 Desktop CPU Line
For now, the line features 4 CPUs: the 16-core Ryzen 9 5950X, the 12-core Ryzen 9 5900X, the 8-core Ryzen 7 5800X and the 6-core Ryzen 5 5600X. The CPUs will be available on Nov. 5.
With AMD once more relying on Taiwan Semiconductor’s (TSM) – Get Report 7-nanometer (7nm) manufacturing process node, clock speeds for the new CPUs generally aren’t much different than those of comparable products relying on AMD’s Zen 2 microarchitecture, which was first unveiled in mid-2019. For example, the 5950X has a 3.4GHz base clock speed and a boost clock speed of 4.9GHz, which respectively compares with 3.5GHz and 4.7GHz base and boost clocks for its predecessor, the 16-core Ryzen 9 3950X.
The other three CPUs have base clocks of either 3.7GHz or 3.8GHz, and boost clocks ranging from 4.6GHz to 4.8GHz. As a result, AMD is still differentiating its mid-range and high-end Ryzen desktop offerings primarily via core counts rather than clock speeds.
But while clock speeds aren’t changing much, AMD claims Zen 3 delivers a 19% performance gain in terms of instructions per clock (IPC). This gain — the result of a slew of architectural improvements, including a new cache
