Submission + - AMD Ryzen 5000 Series Processors Set A New Performance Bar Over Intel (hothardware.com)

Submitted by MojoKid
MojoKid writes: AMD made bold claims when the company unveiled its new Zen 3-based Ryzen 5000 series processors early last month. Statements like "historic IPC uplift" and "fastest for gamers" were waved about like flags of victory. However, as with most things in the computing world, independent testing is always the best way to validate claims. Today AMD lifted the embargo on 3rd party reviews and, in testing, AMD's new Ryzen 5000 series CPUs set a new performance bar virtually across the board, and one that Intel currently can't touch. There are four processors in the initial Ryzen 5000 series lineup, though it's a safe bet more will be coming later. The current entry point is the Ryzen 5 5600X 6-core / 8-thread processor, followed by the 8-core / 16-thread Ryzen 7 5800X, 12-core / 24 thread Ryzen 9 5900X, and the flagship 16-core / 32-thread Ryzen 9 5950X. All of these new CPUs are backwards compatible with AMD socket AM4 motherboards. In comparison to Zen 2, Zen 3 has a larger L1 branch target buffer and improved bandwidth through multiple parts of its pipeline with additional load/store flexibility. Where Zen 2 could handle 2 load and 1 store per cycle, Zen 3 can handle 3 load and 2 stores. All told, AMD is claiming an average 19% increase in IPC with Zen 3, which is a huge uplift gen-over-gen. Couple that IPC uplift with stronger multi-core scaling and a new unified L3 cache configuration, and Zen 3's performance looks great across a wide variety of workloads for both content creation and gaming especially. AMD's Ryzen 9 5950X, Ryzen 9 5900X, Ryzen 7 5800X and Ryzen 5 5600X will be priced at $799, $549, $449 and $299, respectively and should be on retail and etail shelves starting today.

Submission + - Intel Is Patching Its 'Zombieload' CPU Security Flaw For the Third Time (engadget.com)

Submitted by Anonymous Coward
An anonymous reader writes: For the third time in less than a year, Intel has disclosed a new set of vulnerabilities related to the speculative functionality of its processors. On Monday, the company said it will issue a software update "in the coming weeks" that will fix two more microarchitectural data sampling (MDS) or Zombieload flaws. This latest update comes after the company released two separate patches in May and November of last year.

Compared to the MDS flaws Intel addressed in those two previous patches, these latest ones have a couple of limitations. To start, one of the vulnerabilities, L1DES, doesn't work on Intel's more recent chips. Moreover, a hacker can't execute the attack using a web browser. Intel also says it's "not aware" of anyone taking advantage of the flaws outside of the lab.

Submission + - AMD Launches Threadripper 3970X, 3960X And Smokes Intel's New 18-Core CPU (hothardware.com)

MojoKid writes: Intel and AMD have been duking it out in the high-end desktop processor space lately. AMD's return to competitive footing versus Intel has propelled the company forward and the brand has a loyal, passionate following due the competitive performance-per-dollar its 3d Gen Ryzen processors bring versus Intel offerings. Today, both companies have launched new flagship many-core CPUs, the Intel Core i9-10980XE, which is an 18-core chip, and the AMD 3rd Gen Threadripper 3970X and 3960X, which are 32-core and 24-core chips, respectively. Intel's Core i9-10980XE brings a lower price of $999 and competes more favorably versus AMD's lower-end 16-core Ryzen 9 3950X that's priced at just $750. Meanwhile, the new AMD Threadripper 3960X at $1399 and Threadripper 3970X at $1999 leave Intel's fastest desktop chip in the dust in multi-threaded workloads, sometimes by a wide margin. In addition, while Threadripper 3960X and 3970X pull only about 26 to 36 Watts of additional power versus Intel's new Core i9-10980XE, they do it with 33% — 77% more core resources. Regardless, it's impressive how the tables have turned, as AMD is now firmly entrenched with some better value propositions in high-end desktop processors, and better performance in many cases as well.
