The GPU is the "heart" of the graphics card, which is equivalent to the role of the CPU in the computer. It determines the grade and most of the performance of the graphics card, and it is also the difference between 2D and 3D graphics cards. 2D display chips mainly rely on the CPU's processing power when processing 3D images and special effects, known as "soft acceleration". The 3D display chip is the three-dimensional image and the special effects processing function is concentrated in the display chip, which is the so-called "hardware acceleration" function. The display chip is usually the largest chip (and the one with the most pins) on the display card. The GPU makes the graphics card less dependent on the CPU and does some of the work of the CPU, especially in 3D graphics processing. The core technologies used by GPU include hardware T&l, cubic environment material mapping and vertex mixing, texture compression and bump mapping, dual texture

  CPU   Generally speaking, the CPU computing power is the weakest, although the CPU has the highest main frequency, but the single is also 8 cores, 16 cores, a core of 3.5g, 16 cores is 56g, and then consider the instruction cycle, up to 30g times per second multiplication. Still fixed point.   D SP   Although the main frequency of the DSP is not as good as the CPU, but the multiplier is more, casually with 16 multipliers, or floating point. And then a 4 cores, 8 cores, and specific algorithms hardware acceleration, so although the main frequency is only 1,2g but the computing power is still stronger than the CPU. Of course, now there is a CPU with a dedicated multiplier, DSP also set the ARM core, the boundary between the two began to blur.   All DSP calculations use floating point algorithms, and there are no bit or integer instructions yet.   GPU   GPU is designed for image processing, the main frequency is generally around 500mhz, but there are many cores, such as titan, there are

Recently, Infineon , Renesas , Texas Instruments, Rapidus and other chip giants have started to build new wafer plants, the industry estimates that the four major companies in the production expansion of the amount of 25 billion dollars.   Infineon: 5 billion euros to build a factory in Germany, the largest single investment in history   On Feb. 16, Infineon said it had received approval to build a 5 billion euro ($5.35 billion) chip plant in Dresden,  Germany, scheduled to start production in 2026 . Infineon said it would be the largest single investment in its history and was expected to create about 1,000 jobs. The company is seeking 1 billion euros in public funds for the project.   Infineon also said the planned plant, which will produce power semiconductors and analog/mixed-signal components, would generate roughly the same annual revenue as the investment at full capacity.   The German economy ministry approved early projects for the plant, allowing Infineon to start constructio

 According to news reports, a train carrying toxic chemicals derailed in eastern Ohio on the night of Feb. 3, sparking a fire. The local emergency department carried out a "controlled release" of toxic gas on board the train on the 6th, resulting in the emergency evacuation of residents within a few kilometers due to the threat of deadly gas. Due to the serious toxic gas pollution in the area, may have a significant impact on the local Intel, Honghai Foxconn, LG Energy, and other factories. U.S. train derailment caused the spread of toxic gases Australia News 13 reported that this incident has caused the problem of toxic gas diffusion has led to coughing, diarrhea, tears, no appetite, and other symptoms of poisoning in nearby animals. The freight train in question, with about 50 cars, derailed in the eastern Ohio town of East Palestine, adjacent to Pennsylvania, on the night of the 3rd, sparking a fire. According to the operator Norfolk Southern Corporation, there are 10 cars

Despite the challenging market environment, ASML ended fiscal 2022 with net sales of €21.2 billion, up 13.8 percent year-over-year, and net income of €5.6 billion, down 4.4 percent year-over-year. ASML expects to grow net sales by more than 25 percent in 2023.   In the fourth quarter of 2022, the Veldhoven, Netherlands-based company reported net sales of €6.4 billion, at the midpoint of its guidance range, and net income of €1.8 billion. "Bookings are good," said ASML CEO Peter Wennink in a video interview posted on the company's website following the release of quarterly and annual results. "We booked more than €6 billion in bookings, resulting in a record backlog of more than €40 billion by the end of 2022. That's something [we've] never seen before, so the backlog sets a core record."   Gross margin was 51.5 percent in the fourth quarter and 50.5 percent for the full year.   "It was a pretty good year with good performance in some challenging cir
