Zenbleed: Everything you need to know about this AMD security bug
The latest in a long series of security bugs for CPUs, Zenbleed is yet another thing that needs to be patched. Here's what you need to know.
After the Spectre and Meltdown CPU exploits were publicized in 2018, the computing world has been pretty vigilant about finding security bugs and loopholes in processors, and in the past five years, researchers have found a ton. On July 24, yet another exploit was publicly disclosed after first being reported in May. This time, it's specific to AMD processors built on the Zen 2 architecture, and it's dubbed termed "Zenbleed". Here's everything you need to know about Zenbleed and what it means for the world.
AMD adds 128-core Bergamo and 3D V-Cache Genoa CPUs to Zen 4 Epyc lineup
AMD breaks records by launching a 128-core server CPU, a chip with 1GB of L3 cache, and a GPU with 192GB of VRAM.
Ever since its launch in 2017, AMD's Epyc server CPUs have offered some of the highest core counts for high-performance server chips. Epyc has gone from 32 cores with the original Zen, to 64 cores with Zen 2, and 96 cores with Zen 4, but Epyc is hitting 128 cores today as AMD launches its Zen 4c architecture, which is designed to deliver better core density and power efficiency than Zen 4. Additionally, AMD is also releasing 96-core Epyc chips with 3D V-Cache, the first CPUs to offer 1GB of L3 cache.
