AMD released its Zen 3 desktop processors last October, and if you've been looking for the PCIe 5.0 .
The Zen 4 chips might just be worth holding out for if you can wait another year to upgrade, with a report from Chipsandcheese (via Wccftech) claiming some pretty impressive gains over the previous generation. These include IPC gains of 25%, and total performance improvements of 40%.
The source is careful to state that they can't say whether this is an over-exaggeration, and we'd agree with their cautiousness. But, thanks to the Zen 4 chips being on a smaller 5nm process as opposed to the 7nm Zen 3 chips, these gains do sound plausible. Putting it into context, AMD's first generation Ryzen processors had a 52% IPC gain over the previous Excavator architecture.
We'll have to wait for real benchmarks and inevitable leaks of more information on Zen 4 chips to see if this rumour holds true, although Chipsandcheese's 'trusted source' claims that a Zen 4 server chip, in an identical core configuration to a Zen 3 equivalent, had performance improvements of 29%.
With Intel's 12th generation next month's Rocket Lake chips to 10nm for Alder Lake, it should bring some impressive IPC gains like those rumoured for Zen 4.
