Intel Tiger Lake, architecture of the new CPUs

Intel Tiger Lake is ready to compete with AMD’s Ryzen 4000 Mobile in mobile computing thanks to an entirely new architecture, a redesigned manufacturing process, higher CPU performance with increased frequencies and caches, better power efficiency and a next-generation integrated graphics that promises great potential.

Intel is not going through its best moment due to the delay in the production of chips; the troublesome transition to 10 nm processes; increased competition from AMD and the repercussions that Apple silicon will have for the industry. But we already anticipated that the chip giant has talent and means to overcome the situation.

The company has held the virtual event «Architecture Day 2020» to detail the progress in the six pillars of technological innovation you are working on: processes and packaging, architecture, memories, interconnections, security and software. A technical appetizer for the product presentation expected on September 2. We already gave you a full account of the graphic section yesterday and today we will review what we can expect from the new processing platform.

Intel Tiger Lake, architecture

Intel has spent years refining its FinFET transistor technology that began with the 2012 ivy bridges. That technology enabled Intel to design “3D” transistors that were much faster and more efficient than previously used flat designs. With Intel Tiger Lake you are ready for the next leap.

The company calls it «SuperFin«, An acronym to explain that it uses SuperMIM capacitors and redesigned FinFET transistors. The overall technological process continues at 10 nm, but it is an interesting hint of what the final 7-nanometer developments should offer when they hit the market. The result is that these “Tigers” will represent the largest single intranode upgrade in Intel history.

Also interesting (at the marketing level) that Intel uses an understandable name to define the processes and not the usual ++++ used in recent years. Intel’s own engineers explained that even they sometimes have a hard time remembering which variant + have specific updates or which product is built on which node +. These types of definitions have become as confusing for clients as it is for experts.

The processing cores are also new, the Willow Cove They must beat the current Sunny Cove of the “Ice Lake” platform on all terrains. Intel promises a 10-20% CPU performance increase over its Ice Lake counterparts. This is achieved with the new architecture, the greater number of L2 and L3 caches and a considerable increase in the working frequency with values ​​close to 5 GHz in turbo mode.

It should be mentioned that increasing clock speeds will not lead to higher power consumption. The Willow Cove have a larger dynamic range and higher efficiency than Sunny Cove processors; they can operate at lower and higher voltages, and their frequencies are also higher at the same voltage. If you are interested in technical details, Anandtech has published an article (as impressive as usual) with all the information.

Intel Tiger Lake, other news

Another point of interest of these Intel Tiger Lake will be the graphic section. The processors will debut integrated Gen 12 graphics based on the new Xe line that will also produce Intel’s first dedicated in 20 years. They will feature up to 96 execution units and significant efficiency improvements in performance per watt. From the previous tests we know of so far, they are expected to double the performance of the Intel HD and outperform the NVDIA GeForce MX350.

More news will come to the section of the memories with the premiere of the support for LPDDR5. These processors will be able to handle a memory bandwidth of up to 86 GB / s, support LP4x-4267, validated DDR4-3200 and LPDDR5 up to 5400 MHz.

The Intel Tiger Lake will also be the first to offer integrated support for the new Interface Thunderbolt 4. Connected to USB 4, it maintains the highest performance in the industry with 40 Gbps of bandwidth, it will be able to increase the size of the cabling, the maximum of ports and in short it will become the external connectivity standard of the future.

Other improvements cited by Intel will come from the “massive” performance increase in Artificial Intelligence tasks and lower CPU overhead with a new Gaussian network accelerator (GNA 2.0).

Intel has left the announcement of models for the next event to be held on September 2. We assume that there will be Core i3, i5 and i7 versions to cover the entire spectrum of mobile computing needs for which they are designed. Yesterday we saw one of them in the leak of an HP Pavilion. A Core i7-1165G7 with four processing cores (twice as many threads) that surprised by a maximum frequency of 4.8 GHz.

We will not advance events, but Intel Tiger Lake will be a breakthrough. On September 2 we will tell you more.
