  • “To enable the massive 256GB/s memory bandwidth that Ryzen AI Max delivers, the LPDDR5x is soldered,” writes Framework CEO Nirav Patel in a post about today’s announcements. “We spent months working with AMD to explore ways around this but ultimately determined that it wasn’t technically feasible to land modular memory at high throughput with the 256-bit memory bus. Because the memory is non-upgradeable, we’re being deliberate in making memory pricing more reasonable than you might find with other brands.”

    There’s a certain amount of stuff that’s more or less common to all computer programs: the need to get input from and display output to the user, the need to interact with various features of the hardware (e.g. saving data to disc), etc. A lot of the code in the program is infrastructural boilerplate, transforming and moving around data between those things.

    “Business logic” is everything else – the code implementing the computation that fulfills the program’s purpose, described in terms of the problem domain.

    For example, if you’re “manipulating a string” that’s probably infrastructural code, whereas if you’re “formatting a mailing address” that’s probably business logic.

    The common sorts of apps that exist to automate some straightforward bureaucratic workflows (i.e. filling out forms, but on a computer) are often designed with a “three tier” application architecture. The first tier is the UI, the third tier is the database store, and the middle tier is the business logic doing the calculation and validation that a clerk would’ve done by hand in the previous paper-based process.

    Apps that operate in a more complicated way, such as CAD software, might tend to have a fuzzier distinction between business logic and infrastructural code.
