The Rocket Lake Desktop CPU from Intel has been tested, and Fritzchens Fritz shared some super high-resolution die shots on Twitter. Fritz is well known for posting super detailed die shots of several latest chips in the tech segment.
The Rocket Lake CPU which has been tested is Intel Core i5-11400. It comes with 6 cores and 12 threads. This chipset is one of the most budget-friendly chips within the Rocket Lake series and offers a clock speed of up to 4.4 GHz. In contrast, it features the brand new Cypress Cove architecture that does deliver double-digit IPC gains to boost its in-game performance and general applications.
The Intel Core i5-11400 Rocket Lake Desktop CPU was tested without a heatsink while being delidded. Fritz has used a copper spacer to get the chip to boot which is a necessary step to get to the windows. The CPU becomes slightly hotter at this time before reaching a lower power state. By using Hydrochloric Acid, the thermal interface material over the die was cleaned off.
The copper spacer was removed from the Intel Core i5-11400 Rocket Lake Desktop CPU after booting it into the operating system. The chipset has been tested in both single-core and multi-core within the same benchmark to compare it, in single-core the Core i5-11400 has scored 220 points, whereas 1600 points in multi-core.
Skipping the performance result, the thermal imaging part became the most interesting thing to see as it shows the multiple cores operating on the die. Previously Fritz has done this with the AMD Ryzen 4000 Renoir APU on a laptop chip, but this is the first time we have seen a desktop chipset in action. If we look at the Cypress Cove cores and the Rocket Lake chip in general, it is clear.
