The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively. Hardware Past As Performance Prologue. Regardless, the overall story for hardware progress remains grim, particularly when we recall how long device replacement cycles are: Tap for a larger version. Mind The Gap. Tap for a larger version.

When even a bit of React can be a problem on devices slow and fast alike, using it is an intentional choice that effectively excludes people with low-end hardware. A ASUS X550CC laptop from 2013 running Windows 10 on Chrome 83. It makes organizing code easier. I think JSX is great. An old first generation iPhone SE on Safari 13.

Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. The latest AWS hypervisor, Nitro, uses everything to provide a new hardware-assisted hypervisor that is easy to use and has near bare-metal performance. I'd expect between 0.1%

It will also use less power than a two-socket Intel server, with a lower hardware cost, and potentially lower licensing costs (for things like VMware). This is the first time any server vendor has even bothered to submit a TPC-E result for an AMD-based system since 2013. Higher memory speed and bandwidth. Lower power usage.

The following examples use the public Stack Overflow 2013 database ( download details ), with a single index added: CREATE INDEX PP ON dbo. This uses hardware, typically a crystal oscillator, that produces ticks at a very high constant rate regardless of processor speed, power settings, or anything of that nature.
