10 nanometers: Intel 11 generation core, performance increased by 20%, AI computing power multiplied by 5 times

The long rumored 11 generation core has been officially released. Tiger Lake’s launch today heralds the official launch of Intel’s 10 nanometer chip. This time, the first model of the new CPU is the mobile version. Intel has positioned it as “the best lightweight notebook processor in the world”. < p > < p > in August this year, Intel held a rare “Architecture Day” full of dry goods, revealing some information about the upcoming tiger Lake processor. Today, these products are on sale, and Intel offers faster and more powerful AI processing power in the next generation of core CPUs. The notebook, which will be launched at the end of this year, will surely improve its performance. < / P > < p > Intel has already told us that the standard form of tiger lake is a four core eight thread processor, which has the latest Intel manufacturing process and an upgraded graphics processing architecture. < / P > < p > the 11th generation core adopts Intel’s latest generation of willow Cove microarchitecture, which is slightly adjusted compared with sunny cove. Tiger Laker’s core offers higher performance than ever before: the peak frequency of the new CPU reaches 4.8 GHz, an increase of 20% compared with the previous generation’s 4.0 GHz. Originally, Intel’s strength was in the single core frequency, but now it looks stronger. < / P > < p > the frequency gain mainly comes from the improvement of process. First of all, 10nm finally comes: to be exact, it should be the Intel 10nm + + process, which was renamed superfin technology by Intel. The improvement of this manufacturing process is in two aspects: first, to improve efficiency and scale to achieve higher frequency, but also to be easy to produce. Therefore, the chip we finally see has higher frequency and performance than the previous generation, and the power consumption is the same as the previous generation. < / P > < p > in graphics computing, tiger lake uses Intel’s next-generation graphics architecture Xe LP. In short, Xe LP increases the number of original threads and computation per execution unit, and improves other details such as cache structure. On the ice lake processor, we can have 64 EU running at 1100 MHz, while on tiger lake, we will see 96 EU running at 1350 MHz. Combined with other improvements, we can see that tiger lake has doubled the graphics processing power of the previous generation. Other improvements to tiger Lake include support for local thunderbolt 4, which is embedded in the CPU and supports up to four lightning 4 interfaces per device. Intel also provides Wi Fi 6 support through the cnvi interface. Intel’s power / frequency algorithm has also been updated to extend power and clock speed on CPU, GPU and memory structures, respectively. Intel says the new CPU has doubled the bandwidth of the internal structure, allowing more data to communicate between all of these components. < / P > < p > the 11th generation mobile core processor further improves the integration level of the chip, with smaller PCB area and higher efficiency. That’s good news for thin laptops. < p > < p > with Intel’s deep learning acceleration instruction set, tiger Lake provides the first instruction set dp4a for neural network reasoning on integrated graphics card, and provides native support for int8 data type for the first time, which can improve AI performance by up to five times. < p > < p > Intel’s tiger Lake today is different from the past in that it focuses more on end-user performance, that is, the speed and benchmark number that end users often use to compare with other products on the market. In addition, Intel partners are now free to announce future tiger Lake based products. < / P > < p > next, we will focus on the processor details. Intel first launched two types of tiger Lake chips with power from 7W to 28w. The figure below shows tiger Lake’s up3 part: < / P > < p > these mid and high-end 12-25w processors are technically called “up3” processors, which are also commonly referred to as U-series processors. Although the TDP of these processors is 15W, notebook manufacturers can adjust the power up or down according to the way they build the system. < / P > < p > Intel divides processors by number of cores, graphics cards, and frequencies. Any processor listed as “G7” means having the highest level of graphics card. However, it should be noted that there are still differences. For Core i7 components, it is 96eu, for core i5, it is only 80eu, and L3 cache is less. Next comes the G4 graphics card, which has only 48 execution units. Further down, the 7-15w processor is the “Y-series” processor of the past, now known as the up4. There is only one Core i7 processor in the power range of < / P > < p > and the remaining core i5 has less EU and lower frequency. Core I3 is divided into four core and dual core processors that only support 48eu. < / P > < p > the power setting of these processors in the up4 range is mainly due to the low fundamental frequency, which is also a major feature of Intel low-power processors for many years. < / P > < p > the goal of the next generation processor is to expand from a fanless design of about 9W in the up4 power range to models up to 28w, and even with stand-alone GPUs. As with Intel’s 10th generation processors, users want to see tiger Lake design in the power range of 25-28w, using the highest performance processor and ensuring higher power mode. This will allow products with tiger Lake processor to provide better continuous performance after the end of REMAX, such as rendering and video coding. < p > < p > Intel said that tiger lake has a better frequency algorithm, which enables the system to increase the CPU / GPU frequency in the frequency up window as required. The entire system is a feedback loop and inputs the workload, on-system sensors, power limits and balancers to generate the correct frequency. < / P > < p > Intel’s “TDP” value, also known as power limit 1, maintains power between 7W and 28w depending on the system and may be much higher in turbo mode. Over the years, the secondary power level pl2 has been increased to + 4W and + 20W on TDP. For the previous generation of ice lake, the peak value of 15W processor can reach 44w in turbo mode. What does this mean for tiger lake? According to Intel’s own data, the peak power of Rui frequency can reach about 50W in both plug-in and power-off situations. What Intel wants to emphasize to customers is that its turbo algorithm can achieve a consistent user experience when the system is connected to power or only runs on battery. < / P > < p > unlike previous generations of processors, Intel can test its mobile development platform before product launch, but it is uncertain which tiger Lake product will be the first to be tested in the lab. < / P > < p > with the mix of x ^ e graphics cards and tiger lake, Intel also launched a new product logo. This is the third time Intel has completely changed its logo. The logo of < / P > < p > is shown in the figure below. In the new design, Intel has decided that the “core” and “iris” in the new logo need to use mixed case, but “Intel” is still fully lowercase, “powered by” is fully capitalized, and E in “x ^ e” is still superscript. < / P > < p > the Intel Athena project verification program was launched with the release of the previous generation of products. It contains a series of verification standards, such as minimum battery life requirements, support for thunderbolt and Wi Fi 6, good display effect, support AI performance and a certain level of response ability. < / P > < p > while launching tiger lake, Intel is also vigorously promoting the Athena project. Any device that meets the latest updated specifications is called the “Intel Evo” certification program. Evo is clearly intended to call for the evolution of a new generation of products. < / P > < p > therefore, as long as OEM notebooks are labeled with this label, it means that their products have passed the Intel Evo platform index test, thus ensuring the user experience. < p > < p > Intel says we’ll see computers based on Pentium, Celeron and the new vPro later this year. DG1 independent graphics card platform may also bring us surprise. < / P > < p > the new tiger Lake mobile end processor will appear in laptops of various manufacturers in the next few weeks. At present, Acer, ASUS, Dell, HP, Lenovo, LG, MICROSTAR, raptor, Samsung and other manufacturers are known. They are expected to launch more than 150 notebooks equipped with the 11th generation intel core processor. However, Intel still has some high-end CPUs that have not been released. On the architecture day in August, the company said that tiger lake could reach 65W, which means there will be 8-core processors in the plan. But so far, there has been no news.
