Mystery Intel Tiger Lake Engineer Sample With All Cores Turbo At 4.0GHz And Single Core Turbo Of 4.3GHz Spotted

An unannounced Intel Tiger Lake SPU Engineering Sample was recently spotted. The interesting aspect of the mystery Intel processor is that it is capable of running all cores turbo at a Clock Speed of 4.0GHz. The all-core powerful Intel CPU can also hit 4.3GHz but on a single Core Turbo setting. Although the speeds are still a little lower than the highly mature and somewhat aging 14nm Fabrication Process, these frequencies and the all-core setting is certainly a significant improvement.

An unnamed Intel Tiger Lake CPU with all-core Clock Speed of 4.0GHz is certainly important for the company currently struggling against AMD and the latter’s Threadripper and Ryzen CPUs. Intel was reportedly facing a lot of trouble moving beyond the long-used 14nm Fabrication Process. The company was even rumored to skip the next logical evolutionary step and move directly to the 7nm Production Process. However, the latest mystery CPU not only dispels the rumors but strongly indicates Intel is confidently making some significant improvements in the 10nm Fabrication Process. While AMD might have comfortably moved onto the 7nm Fabrication Process, Intel is cautiously approaching the steady miniaturization of CPU die sizes.

Mystery Intel Tiger Lake Engineering Sample Reveals Company’s Future Roadmap?

The news about Intel Tiger Lake Engineering Sample (ES) CPU with a clock speed of 4.0 GHz turbo on all of its cores and a single-core turbo of 4.3 GHz was first leaked through a Tweet from Komachi Ensaka. The Twitter user has offered reliable information about unreleased CPUs and processors. CPU enthusiasts will instantly realize that these Clock Speeds aren’t impressive. In fact, Intel’s mobile Comet Lake processors, built on the aging 14nm Fabrication Process, can confidently go up to 4.9 GHz. Still, the leaked frequencies mark a sharp improvement over Ice Lake’s Clock Speeds.

The chip has a total of 4 cores and 8 threads. There’s no other information such as cache and iGPU mentioned. The Tiger Lake-U engineering samples were tested at both 15W and 28W. the 15W Tiger Lake-U chip is reportedly around 17 percent faster than the Ice Lake-U processor. The 28W variant is around 31 percent faster, and around 18 percent faster.

Incidentally, the frequencies posted by the Twitter user are ‘Boost Speeds’. In a follow-up Tweet, Ensaka clarified that the mystery Intel Tiger Lake CPU’ Base Clock Speeds aren’t yet known. Despite the clarification, these Boost Speeds, and that too on all Cores is still a significant improvement, agreed several CPU enthusiasts. This is because the fastest Ice Lake SKU, the Intel Core i7-1065G7, has a single-core turbo of 3.9 GHz and an all-core boost of 3.5 GHz.

Experts point out that the unannounced 10nm mystery Intel Tiger Lake CPU is still an Engineering Sample. In other words, final clock speeds, Base and Boost, could be even higher. The clock speed increase should indicate Intel’s focused efforts to further improvements of the 10nm process. It is no secret that the 10nm fabrication node has struggled to match or exceed the performance of Intel’s exceptionally optimized 14nm process.

The Intel Core i9 9900K, for example, is capable of hitting 5.0 GHz on all cores. In addition to the clock speed barrier, there are reportedly certain ‘yield issues’ with the new 10nm CPUs as well. The Intel Ice Lake CPUs are built on the 10nm+ architecture, but the Tiger Lake is set to be manufactured on the improved 10nm++ process. This should explain the noticeable boost in the Clock Speeds.

Intel 10nm++ Tiger Lake CPUs With Willow Cove Architecture To Arrive Next Year?

Reports indicate that Intel Tiger Lake will feature the significantly improved and optimized Willow Cove architecture. Needless to add, this will allow the processors to achieve high single-digit IPC gains and 96 Xe execution units on the graphics side. Incidentally, we recently reported Intel was relying on the same architecture for the Intel Rocket Lake CPUs, which are being manufactured on the 14nm Fabrication Process.

Intel CPUs fabricated on the 7nm node is still a distant dream. The company which was once a market leader in CPU fabrication and sales appears to be lagging behind AMD. However, with the confirmation of the long-rumored Intel DG1 GPU, the company is confidently diversifying into a new segment.
