Researchers discover seven new Meltdown and Spectre attacks | ZDNet

Researchers say they've discovered the seven new CPU attacks while performing "a sound and extensible systematization of transient execution attacks" -- a catch-all term the research team used to describe attacks on the various internal mechanisms that a CPU uses to process data, such as the speculative execution process, the CPU's internal caches, and other internal execution stages.

New Lower-Cost, AMD-Powered M5a and R5a EC2 Instances | AWS News Blog
General Purpose – M5a instances are designed for general purpose workloads: web servers, app servers, dev/test environments, and gaming. The M5a instances are available in 6 sizes.

Memory Optimized – R5a instances are designed for memory-intensive workloads: data mining, in-memory analytics, caching, and so forth. The R5a instances are available in 6 sizes, with lower per-GiB memory pricing in comparison to the R5 instances.

Monday: Intel teases 48-core Xeon. Tuesday: AMD whips covers off 64-core second-gen Epyc server processor • The Register
The physical x64 core count blows away Intel's Xeon compute family, which only just set itself a high-water mark of 48 cores with Cascade Lake AP. Also, that line is still on Intel's 14nm process, whereas AMD is nudging ahead with TSMC's 7nm. AMD also claimed a single-socket Rome can match or outperform a dual-socket Intel Xeon Scalable 8180M setup, when running the ray-tracing C-Ray benchmark, at least.

If you want to rent AMD Epyc bare-metal boxes in the cloud, Oracle hopes you see red • The Register
We're told an Epyc-based bare-metal Standard E2 server can be rented at $0.03 per core per hour, and is available immediately. Oracle claimed this was up to 66 per cent cheaper, on average, per core than general purpose instances offered by competitors, and 53 per cent less than Oracle's other compute instances.
