![]() For example, Intel's upcoming 10nm node is expected to compete with TSMC's 7nm node, despite the numbers not matching up. The way each semiconductor foundry measures can vary from one to another, so it's best to take them more as marketing terms used to segment products rather than exact measurements of power or size. A 22nm transistor can switch on and off well over 100 billion times in one second. The price per transistor has dropped by a factor of about 50,000. Performance doesn't scale exactly with the transistor size, and at such small scales, these numbers aren't as precise anymore. Compared to Intel’s first microprocessor, the 4004, introduced in 1971, a 22nm CPU runs over 4,000 times as fast and each transistor uses about 5,000 times less energy. It's important to note though that while Intel is still on a 14nm node and AMD is set to launch their 7nm processors very soon, this doesn't mean AMD's will be twice as fast. 7nm is effectively twice as dense as the previous 14nm node, which allows companies like AMD to release 64-core server chips, a massive improvement over their previous 32 cores (and Intel's 28). It also allows for smaller die sizes, which reduces costs and can increase density at the same sizes, and this means more cores per chip. Process sizes decreased about fourfold, from 180 nm to 45 nm. Since smaller transistors are more power-efficient, they can do more calculations without getting too hot, which is usually the limiting factor for CPU performance. Over the decade, transistor counts increased by about an order of magnitude, a trend continued from previous decades. The exact method of how this is done is usually referred to as the process node and is measured by how small the manufacturer can make the transistors. And with AMD's next CPUs on TSMC's 7nm process, this marks a chance for them to jump past Intel in performance, and bring some healthy competition to Intel's monopoly on the market-at least until Intel's 10nm "Sunny Cove" chips start hitting shelves.ĬPUs are made using photolithography, where an image of the CPU is etched onto a piece of silicon. With Intel lagging, even mobile devices have had a chance to catch up, with Apple's A12X chip being manufactured on TSMC's 7nm process, and Samsung having their own 10nm process. These new processes are the first major shrinks in a long time, especially from Intel, and represent a brief rekindling of Moore's law. But further shrinking has gotten more complicated, and we haven't seen a transistor shrink from Intel since 2014. Back in the late 90s and early 2000s, transistors shrunk in size by half every two years, leading to massive improvements on a regular schedule. Moore's Law, an old observation that the number of transistors on a chip doubles every year while the costs are halved, held for a long time but has been slowing down lately. I found an Intel history that confirmed that the 8086 transistor count includes potential sites, saying 'This is 29,000 transistors if all ROM and PLA available placement sites are counted. So Why Are These New Processes So Important? For reference, "10nm" is Intel's new manufacturing process, set to debut in Q4 2019, and "7nm" is usually referring to TSMC's process, which is what AMD's new CPUs and Apple's A12X chip are based on.
