Intel took the wraps off its not-so-secret central processing units (CPUs) codenamed Tiger Lake, built with a 10-nanometer manufacturing process. It may as well have been called Tiger Leak.
The 11th Generation Intel Core Processor models include the Intel Core i7-1185G7 chip, with a base 3GHz frequency that can be boosted to 4.8GHz. The Santa Clara, California-based company has dual-core and quad-core variants in the new family, which will be used in high-powered laptops coming this fall.
Intel is also unveiling the Intel Xe 12th Gen integrated graphics processing unit (GPU), which replaces the Iris Plus integrated GPU. It has improved AI performance, Thunderbolt 4 input-output, and software optimizations. Intel said it has 20% better CPU performance and two times the graphics performance than the previous generation. With the integrated GPU, Intel said it can deliver frame rates in games that are twice as fast as previous models. All told, there are nine new Tiger Lake chips.
The chips are the top of the line for now as Intel faces intense competition from rival Advanced Micro Devices, which uses external producers such as TSMC to make its chips and is making historic market share gains. Intel normally makes its own chips, and it is rumored to be talking to TSMC for contract manufacturing, but that deal won’t come in time for Tiger Lake.

“We’re leading the ecosystem forward to deliver new PC experiences,” Intel executive vice president of client computing Gregory Bryant said in a briefing.
Intel showed off laptops from Acer, Dell, HP, Lenovo, and Samsung. The company said it will have 50 more by the holidays and 150 designs for laptops overall. Intel demonstrated that its processor with Xe graphics could beat a machine running Adobe Photoshop on AMD’s 4800U processor, taking only 40 seconds to do a task that AMD took two minutes to do, Intel product marketing engineer Ksenia Chistyakova said. Intel also said that the integrated GPU will “raise the bar” for base performance for a laptop in running games compared to AMD and Nvidia discrete graphics. (It wasn’t clear if Intel was making fair comparisons, since it didn’t provide a lot of detail about the tests).
In July, Intel acknowledged it ran into delays in ramping up its 7-nanometer manufacturing plants. Intel said it is accelerating its transition to 10-nanometer but that its next-generation manufacturing — which would deliver higher production, faster chips, and lower costs — has been delayed. The company’s 7-nanometer-based CPU product timing is delayed by approximately six months relative to prior expectations. The primary issue is the yield of Intel’s 7-nanometer process, which is now trending a year behind the company’s internal targets, based on recent data.
With a 7-nanometer process, the width between circuits is 7 nanometers (a nanometer is a billionth of a meter). By moving from 10-nanometer to 7-nanometer manufacturing, a manufacturer can miniaturize its circuits, cut costs, and speed up performance and production. Intel had a similar delay when it transitioned from 14-nanometer chips to 10-nanometer chips.
AMD was able to exploit that previous gaffe by using external chip producers, and it pulled ahead in the processor performance battles. Bryant said 90% of graphics chips sold last year were integrated solutions.
While the 7-nanometer process is delayed, Intel said the new 10-nanometer process for Tiger Lake uses a SuperFin transistor design that delivers more performance than the previous 10-nanometer process. The new chips also have a redefined metal stack, the company said, with better overall 3D circuitry stacking for better power efficiency and faster interconnection within the chip.
Chistyakova said the laptops coming will have ultrathin and ultralight designs. Dynabook has a 13.3-inch model, the Portege X30W-J, that weighs 1.9 pounds. Among the improvements users will see: consistent responsiveness on battery life, waking up from sleep mode in less than a second, four-hour charges in under 30 minutes on systems with FHD displays, and nine hours of real-world battery life on systems with FHD displays. The new systems should be 20% faster on office productivity apps versus the competition, as well as 2.7 times faster on photo editing and two times faster on video editing, Intel said.
