Security researchers have identified a cyberespionage group that has been stealing data from policy and diplomatic organizations in South America and South Asia since at least 2015. “While cyberespionage attacks are often seen against targets in the U.S., Europe, and Asia, it is much less common to see South American countries targeted,” researchers from Symantec..

Modern microprocessors are a marvel of technological progress and engineering. At less than a dollar per unit, even the cheapest microprocessors on the market are orders of magnitude more powerful than their ancestors. The first commercially available single-chip processor, the Intel 4004, cost roughly $25 (in today’s dollars) when it was introduced in 1971.
The 4-bit 4004 clocked in at 740 kHz — paltry by today’s standards, but quite impressive at the time. However, what was remarkable about the 4004 was the way it shifted computer design architecture practically overnight. Previously, multiple chips were used for processing and were selected …read more

Although AMD has been losing market share to Intel over the past decade, they’ve recently started to pick up steam again in the great battle for desktop processor superiority. A large part of this surge comes in the high-end, multi-core processor arena, where it seems like AMD’s threadripper is clearly superior to Intel’s competition. Thanks to overclocking expert [der8auer] we can finally see what’s going on inside of this huge chunk of silicon.
The elephant in the room is the number of dies on this chip. It has a massive footprint to accommodate all four dies, each with …read more
When we learn about the internals of a microprocessor, we are shown a diagram that resembles the 8-bit devices of the 1970s. There will be an ALU, a program counter, a set of registers, and address and data line decoders. Most of us never go significantly further into the nuances of more modern processors because there is no need. All a processor needs to be is a black box, unless it has particularly sparked your interest or you are working in bare-metal assembly language.
We imagine our simple microprocessor as built from logic gates, and indeed there have been many …read more

As it turns out, the answer is not 42, it’s 42.3 — thousand. That’s how many discrete transistors spread across the 30 m2 room housing this massive computation machine. [James Newman’s] Megaprocessor, a seriously enlarged version of a microprocessor, is a project we’ve been following with awe as it took shape over the last couple of years.
[James] documented his work in great detail, and by doing so, took us on a journey through the inner workings of microprocessors. His monumental machine is now finished, and it’s the ultimate answer to how a processor – and pretty much everything …read more
