AMD announces Zen 3 series 5000 processors

Dr Lisa. Su, AMD CEO has announced the next generation of the company’s mainstream Ryzen processor.  The 5000 series is getting launched with 4 processors out of the gate, promising 19% raw increase in performance-per-clock, well above recent generational improvements.

Ryzen 7 5800X 8c/16t 3800 4700 32 MB 105 W $449
Ryzen 5 5600X 6c/12t 3700 4600 32 MB 65 W $299*

As you can see, AMD will no longer be providing a CPU cooler for chips above 65W TDP – citing that in its research that customers who buy the higher power processors almost always prefer to use their own cooler to eke out more performance when at full load.  Which is true in a sense, while serviceable at idle or regular load, at full tilt you’d want a bigger cooler than what AMD provides out of the box.


At face value, a 19% increase in performance in the same process node is impressive (even more impressive than Zen+ to Zen 2 improvements) but we need to wait for third party benchmarks to validate these claims.

As teased by AMD, the single core performance of it’s top end 5900X chip is the highest so far in main stream class processors.  Again, something we need to wait others to validate.

One of the biggest improvements that AMD is touting is the merger of the previous 4 core CCX into an 8 core one.  This means less tinkering with apps that only work with one numa node, less latency when accessing the L3 cache and power savings.

This means that under most work load, we should see performance improvements across the board with the only downside the new pricing on these chips.

For upgraders, the 5000 series will be compatible with 500 series chipset motherboards at launch with compatibility being added to older chips via firmware updates

The new Zen 3 processors will hit the market globally  on November 5th so make sure your wallet is ready.
