Intel cripples programs on AMD chips

Filed under

Legal

Intel's compilers recognise when they're running on an AMD processor, and generates code that either degrades performance or causes it to crash. That's one of the many accusations in AMD's lengthy document of complaints against Intel in its recent lawsuit against the chip giant.

The paragraph in question, number 123, reads:

"Intel has designed its compiler purposely to degrade performance when a program is run on an AMD platform. To achieve this, Intel designed the compiler to compile code along several alternate code paths. Some paths are executed when the program runs on an Intel platform and others are executed when the program is operated on a computer with an AMD microprocessor. (The choice of code path is determined when the program is started, using a feature known as "CPUID" which identifies the computer's microprocessor.) By design, the code paths were not created equally. If the program detects a "Genuine Intel" microprocessor, it executes a fully optimized code path and operates with the maximum efficiency. However, if the program detects an "Authentic AMD" microprocessor, it executes a different code path that will degrade the program's performance or cause it to crash."

Among the other issues raised by AMD were:

- That Intel used illegal subsidies to win sales and, in some cases, threatened companies with "severe consequences" for using or selling AMD products.

- That Intel has allegedly abused its dominate market position by forcing major customers into exclusive deals in return for outright cash payments, discriminatory pricing or marketing subsidies.

Following AMD's accusations, representatives of the European Commission and of national competition authorities carried out on-site inspections of several Intel offices and of the offices of an undisclosed number of PC manufacturers, as part of "an ongoing competition investigation", according to an EC spokeswoman.

Oracle Adds Initial Support for Linux Kernel 4.14 LTS to VirtualBox

Oracle recently updated their VirtualBox open-source and cross-platform virtualization software with initial support for the latest Linux 4.14 LTS kernel series. VirtualBox 5.2.2 is the first maintenance update to the latest VirtualBox 5.2 stable series of the application, and it looks like it can be compiled and used on GNU/Linux distribution running the recently released Linux 4.14 LTS kernel. It also makes it possible to run distros powered by Linux kernel 4.14 inside VirtualBox VMs. Read more

    The planned obsolescence is even worse with tablets and smartphones, whose components are all soldered down. The last tablet with a removable battery was the Dell Venue 11 Pro (Haswell version) announced in October 2013, but it was an expensive Windows device that cost as much as a mid-range laptop. The last Android tablet with a removable battery was the Samsung Galaxy Note 10.1 (GT-N8000 series), released in August 2012. It is still possible to find mid-range smartphones with removable batteries. Last year the only high end phones with removable batteries were the LG G5 and V20, but even LG has given up on the idea of making phones that will last longer than 2 years once the battery starts to degrade after roughly 500 full charge and discharge cycles. Every flagship phone introduced in 2017 now has its battery sealed in the case. According to the gmsarena.com database, the number of new smartphone models with non-replaceable batteries grew from 1.9% in 2011 to 26.7% in 2014, and now to 90.3% in 2017. It is highly likely that not a single model of smartphone introduced next year will have a replaceable battery.
