The company also announced the details of the Willow Cove micro-architecture and the Tiger Lake SoC architecture for mobile clients, and for the first time introduced the fully scalable Xe graphics architecture. These innovative architectures can serve the consumer, high-performance computing and gaming application markets. Based on Intel's "decomposition design" approach, combined with advanced packaging technology, XPU products and software-centric strategy, Intel's product portfolio is committed to providing customers with leading products.

10nm SuperFin technology

● After years of improvements to FinFET transistor technology, Intel is redefining the technology to achieve the most powerful single-node performance enhancement in its history, bringing performance improvements comparable to full-node conversion. The 10nm SuperFin technology realizes the combination of Intel enhanced FinFET transistors and Super MIM (Metal-Insulator-Metal) capacitors. SuperFin technology can provide enhanced epitaxial source/drain, improved gate process and additional gate pitch, and achieve higher performance by:

Enhance the extension of the crystal structure on the source and drain to increase strain and reduce resistance to allow more current to pass through the channel

● Improve the gate process to achieve higher channel mobility, so that charge carriers move faster

● Provides additional gate pitch options to provide higher drive currents for chip functions that require the highest performance

● The use of a new thin-walled barrier reduces the via resistance by 30%, thereby improving interconnect performance

● Compared with industry standards, the capacitance has increased by 5 times in the same footprint, thereby reducing voltage drop and significantly improving product performance. The technology is realized by a new type of "High-K" (Hi-K) dielectric material, which can be stacked in ultra-thin layers with a thickness of only a few angstroms to form a repeating "superlattice" structure. This is a leading technology in the industry, ahead of the existing capabilities of other chip manufacturers.

● 10nm SuperFin technology will be used in Intel's next-generation mobile processor code-named "Tiger Lake". Tiger Lake is in production, and OEM products will be available in the holiday season.

Package

Test chips using "Hybrid bonding" technology have been taped out in the second quarter of 2020. The traditional "thermocompression bonding" technology is used in most packaging technologies today, and hybrid bonding is an alternative to this technology. This new technology can accelerate the realization of bump pitches of 10 microns and below, providing higher interconnection density, bandwidth and lower power.

Hybrid architecture

Alder Lake is Intel's next-generation client product with a hybrid architecture. Alder Lake will combine Intel's upcoming two architectures-Golden Cove and Gracemont, and will be optimized to provide excellent performance-to-power ratio.


Xe graphics architecture

Intel detailed the optimized Xe-LP (low-power) micro-architecture and software to provide efficient performance for mobile platforms. Xe-LP is Intel’s most efficient architecture for PC and mobile computing platforms, with a maximum configuration of up to 96 groups of EU units, and a new architecture design, including asynchronous computing, view instancing, and sampler feedback , An updated media engine with AV1 and an updated display engine, etc. This will enable new end-user features with instant game tuning (Instant Game Tuning), capture and streaming, and image sharpening. In terms of software optimization, Xe-LP will improve the driver through the new DX11 path and optimized compiler.


The first Xe-HP chip has been tested in the laboratory. Xe-HP is the industry's first multi-tiled, highly scalable, high-performance architecture that provides data center-level and rack-level media performance, GPU scalability, and AI optimization. It covers the calculation of dynamic range from one block to two and four blocks, and its function is similar to multi-core GPU. At the Architecture Day event, Intel demonstrated that Xe-HP transcodes 10 complete high-quality 4K video streams at a rate of 60 FPS on a single block. Another demonstration also showed the computational scalability of Xe-HP on multiple blocks. Intel is currently testing Xe-HP with key customers and plans to make Xe HP available to developers through Intel® DevCloud. Xe HP will be launched next year.


Intel launched a new variant of Xe microarchitecture-Xe-HPG, which is a microarchitecture optimized for games, combined with the building blocks of Xe-LP's good performance-to-power ratio, and leverages the scalability of Xe-HP Xe-HPC is configured more strongly and the calculation frequency is optimized. At the same time, Xe-HPG adds a new GDDR6-based memory subsystem to improve cost performance, and will have accelerated ray tracing support. Xe-HPG is expected to start shipping in 2021.


Intel® Server GPU (SG1) is Intel’s first Xe-based discrete graphics card for data centers. SG1 achieves the aggregation of 4 DG1s, which can improve the performance to the data center level in a small size to achieve low-latency, high-density Android cloud games and video streaming. The SG1 will be put into production soon and will be shipped later this year.


Intel's first discrete graphics graphics card DG1 based on the Xe architecture has been put into production and is expected to begin delivery in 2020 as planned.

● Intel® Graphics Command Center (IGCC) introduces new features, including real-time game adjustments and game sharpening.

Instant game adjustment is a game-specific driver that can push repairs and optimizations to end users faster than before, and does not require downloading and installing complete drivers. It only requires users to choose to join once in each game.

● Game sharpening uses perceptual adaptive sharpening, an adaptive sharpening algorithm based on computational shaders to improve image clarity in games. This feature is especially useful for games that use resolution scaling to balance performance and image quality, and is an optional feature in IGCC.
