AWS throws its home-grown Arm CPUs at new memory-intensive instance type

Claims Graviton2 thrashes x86 on price/performance, touts lowest-priced memory on the Amazonian cloud


Amazon has found a new use for its home-grown Graviton2 processors – powering a new EC2 instance type optimised for plenty of memory.

The new EC2 X2gd instance type is intended to run databases – including in-memory databases – analytics, caching, or anything else that prefers swimming in deep pools of RAM.

Available RAM in the eight new instances starts at 1 vCPU with 16GB of memory and ascends to 64 vCPUS and a terabyte of RAM. There’s also a bare metal option for the top spec, which we mention as the Graviton2 is thought to possess 64 cores and AWS has confirmed that vCPUs are actually dedicated cores without the ability to handle simultaneous multithreading.

As ever, AWS claims that the new instances are better and cheaper than those it offers powered by x86 servers. For the X2gd, that means a claim they offer 55 percent better price/performance than existing X1 instances.

The CEO of online photo lockers SmugMug and Flickr took to Twitter to offer his own numbers.

AWS also asserts that the new instances offer more RAM, for less cash, than any previous instance type.

The Register will let you write your own spreadsheets to prove that right or wrong. What we can say is that AWS has now put its home-grown silicon behind EC2 instance types for everyday workloads, compute-intensive workloads, bursty apps and now memory-optimized software. And it appears to have done that with the same CPU, rather than offering the smorgasbord of variants that Intel and AMD throw at different applications. ®

  • Twitter founder Dorsey beats hasty retweet from the board
    We'll see you around the Block

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.

  • Amazon investors nuke proposed ethics overhaul and say yes to $212m CEO pay
    Workplace safety, labor organizing, sustainability and, um, wage 'fairness' all struck down in vote

    Amazon CEO Andy Jassy's first shareholder meeting was a rousing success for Amazon leadership and Jassy's bank account. But for activist investors intent on making Amazon more open and transparent, it was nothing short of a disaster.

    While actual voting results haven't been released yet, Amazon general counsel David Zapolsky told Reuters that stock owners voted down fifteen shareholder resolutions addressing topics including workplace safety, labor organizing, sustainability, and pay fairness. Amazon's board recommended voting no on all of the proposals.

    Jassy and the board scored additional victories in the form of shareholder approval for board appointments, executive compensation and a 20-for-1 stock split. Jassy's executive compensation package, which is tied to Amazon stock price and mostly delivered as stock awards over a multi-year period, was $212 million in 2021.
