Intel ‘Tiger Lake’ CPUs, Xe Graphics, 10nm ‘SuperFin’ Course of Detailed

Intel has introduced new particulars of its upcoming shopper CPU and GPU product strains, in addition to 3D Xpoint reminiscence, the 10nm manufacturing course of node, future chip packaging know-how, software program, and rather more, in its digital Structure Day 2020 seminar. Senior engineers together with Raja Koduri, who’s an organization Senior Vice President, Chief Architect, and GM of Structure, Graphics and Software program, talked about Intel’s progress on the product design in addition to manufacturing fronts, providing up details about how Intel intends to be aggressive now and sooner or later.

Beginning with the 11th Gen ‘Tiger Lake’ CPUs, that are anticipated to be introduced as early as the primary week of September, Intel disclosed {that a} mixture of microarchitectural and manufacturing course of enhancements will permit for a a lot wider vary of frequencies than the present 10th Gen ‘Ice Lake’ processor collection. This could permit CPU cores to scale up or down farther than earlier than to accommodate energy saving and efficiency objectives.

Tiger Lake makes use of the ‘Willow Cove’ CPU microarchitecture. Intel’s new in-house Xe-LP built-in GPU with as much as 96 execution models may even debut with this product line. Tiger Lake CPUs additionally characteristic a brand new cache construction and safety measures aimed toward mitigating management stream assaults, plus AI acceleration in addition to built-in Thunderbolt Four and USB 4. PCIe 4.Zero and DDR5 RAM help will make the platform future-ready.

Intel is touting “greater than a generational enhance” in efficiency for this technology, which ought to permit it to make up for among the time misplaced as a consequence of repeated delays with 10nm manufacturing over the previous a number of years. PCs constructed utilizing Tiger Lake CPUs are anticipated to go on sale in late 2020. No additional bulletins had been made in regards to the delayed transition to 7nm following this.

The corporate has dropped its complicated “+” suffixes and can as an alternative use the time period “10nm SuperFin” to model the newest enchancment of its 10nm course of. Intel is asking this the biggest intra-node enhancement in its historical past, because it has improved the construction of its FinFET transistors to enhance efficiency and energy effectivity and not using a generational drop in fabrication dimension. SuperFin transistors are mentioned to permit higher passage of present with improved interconnects, decrease resistance, and lowered voltage droop.

The SuperFin transistors’ enhancements have been achieved utilizing a “tremendous lattice” construction of Excessive-Ok dielectric supplies in a stack measuring a number of angstroms thick. Intel says that that is an industry-leading improvement that’s forward of its rivals’ capabilities, and is already in use with Tiger Lake chips.

Whereas the Xe-LP (low energy) built-in GPU will start rolling out in 2020, Intel additionally detailed plans for Xe to scale as much as discrete graphics playing cards, fanatic gaming PCs, and server in addition to knowledge centre purposes. Xe-LP is just one implementation, and is optimised for dimension and energy. It options as much as 96 execution models and can help asynchronous compute, AI inferencing, an up to date media encode/decode engine, 12-bit color, 4 show pipelines, variable fee shading, adaptive sharpening, and adaptive sync with variable refresh charges as much as 360Hz.

Efficiency in video games for Xe-LP in a 15W bundle is claimed to match or exceed what Intel’s present Gen11 built-in GPU can obtain in a 25W envelope. Intel says customers can anticipate to run video games at excessive settings with higher body charges than present built-in GPUs can handle at low settings.

For PC avid gamers, Intel introduced a brand new Xe-HPG implementation of its high-power Xe-HP GPU, coming in 2021. The one particulars confirmed to this point are that it’ll help {hardware} ray tracing and use GDDR6 reminiscence. Apparently, this GPU shall be manufactured utilizing a third-party foundry and leveraging exterior course of know-how, which Intel just lately indicated it will begin doing to enhance its means to get merchandise to market.

The Xe graphics structure scales from ultraportables to data-centre servers and supercomputers


The high-end Xe-HP variant is designed to be scalable to energy high-end media encoding and streaming in addition to AI acceleration capabilities within the datacentre. It was demonstrated transcoding 10 4K 60fps video streams concurrently on one modular logic block, and as much as 4 of those blocks might be carried out on a GPU.

In different bulletins, Intel confirmed that Alder Lake shall be its subsequent hybrid CPU design, following Lakefield. It should mix next-gen Golden Cove and Gracemont cores for flexibility, energy and effectivity. No additional particulars together with a launch timeframe have been introduced, however it’s extensively anticipated that Alder Lake will kind the premise of the 12th Gen lineup for desktops and laptops.

For servers and datacentres, Intel will ship its next-gen Xeon Scalable CPUs primarily based on the Ice Lake-SP structure later this 12 months, supporting complete reminiscence encryption and PCIe 4.0. Following that, the Sapphire Rapids technology will leverage 10nm SuperFin transistors and can help PCIe 5.Zero with DDR5 reminiscence.

Intel additionally introduced updates on its FPGA product strains, 3D Xpoint persistent reminiscence, 144-layer 3D NAND flash, Loihi neuromorphic processing analysis, next-gen Foveros and EMIB packaging know-how, OneAPI programming mannequin, and DevCloud developer instruments.
