AMD unveils 65W Ryzen 5800 and 5900 CPUs
AMD has unveiled Ryzen 7 5800 and Ryzen 9 5900 CPUs that consume less power than their X counterparts, although they're limited to pre-built PCs.
Lenovo's new budget AMD gaming laptops start at $660
Lenovo recently went a little wild by cramming a 64-core Ryzen Threadripper PRO into an unassuming workstation, but we assume one of those won't be landing on your desk any time soon. Perhaps the most notable of Lenovo's new US-bound releases is the Legion 5, which comes in 15.6 and 17.3-inch variants.
AMD CPUs for the past 9 years are vulnerable to data leak attacks
It's not just Intel chips that are vulnerable to hard-to-fix security flaws. Researchers at the Graz University of Technology have detailed a pair of side channel attacks under the "Take A Way" name that can leak data from AMD processors dating back to 2011, whether it's an old Athlon 64 X2, a Ryzen 7 or a Threadripper. Both exploit the "way predictor" for the Level 1 cache (meant to boost the efficiency of cache access) to leak memory content. The Collide+Probe attack lets an intruder monitor memory access without having to know physical addresses or shared memory, while Load+Reload is a more secretive method that uses shared memory without invalidating the cache line.
Lenovo's latest ThinkPads last even longer between charges
Lenovo has announced the newest additions to its ThinkPad line-up, each boasting improved battery life and increased performance neatly packaged in slim models under three pounds. The T495, T495s and X395 come with up to the 2nd gen AMD Ryzen 7 Pro mobile processors and integrated AMD Vega graphics, Radeon FreeSync for a stutter-free display and, for the AMD series, a brighter 14-inch full HD display at 400 nits.
