Intel Twin Lake E-Core Only Processors Leaked Online: 8-Core N355, N350 and 4-Core N250, N150 Models Included

Intel is set to unveil its latest CPU family under the Twin Lake series, which serves as an enhanced iteration of the Alder Lake-N architecture. This new lineup exclusively features E-cores, designed to optimize power efficiency. Despite minor clock speed adjustments, the core configuration remains consistent with its predecessor.

Intel Twin Lake: Unveiling Four New Processors Focused on Power Efficiency

The Twin Lake series, aimed at ultra-energy-efficient computing solutions, has generated significant buzz on platforms like Geekbench in recent weeks. Today, we delve into the detailed specifications of these processors, which are set to launch across four distinct WeU models: N355, N350, N250, and N150.

Interestingly, the Twin Lake processors represent a refinement rather than a complete overhaul of prior technology. As confirmed through industry leaks, these four variants maintain a similar naming structure to their Alder Lake-N counterparts and continue to support configurations of 4 to 8 total cores.

Performance Analysis of the Twin Lake Chips

Each chip in the Twin Lake family emphasizes efficiency, featuring identical Thermal Design Power (TDP) ratings when compared to earlier models. Starting with the N150, the entry-level variant, it boasts a TDP of just 6W with base and boost clock speeds of 2.9 GHz and 3.6 GHz, respectively. Notably, this represents a 200 MHz increase in turbo boost performance over the previous N100 model.

The integrated graphics unit (iGPU) maintains a count of 24 execution units (EUs) but sees a performance increase, with operating frequencies rising to 1 GHz from the 750 MHz offered in the N100.

In terms of the N250 specifications, we observe enhanced iGPU performance at 1.25 GHz, compared to the N200’s 750 MHz, alongside a modest 100 MHz increase in turbo clock speed. Meanwhile, both the N350 and N355 have received similar enhancements, with an iGPU frequency increase to 1.35 GHz. Despite these adjustments, core count, base clock, and TDP remain unchanged.

Potential Applications and Market Impact

Initial deployments of these processors can already be seen in compact systems such as the Beelink EQ14 Barebone, which entered the market at a remarkably affordable price of $82. The official release of the Twin Lake series is likely to spur a wave of new low-power devices, with expectations of integration into Chromebooks and potential handheld systems depending on the performance metrics achieved by these chips.
