In this case, benchmark entries in both Geekbench 5 and SiSoftware were uncovered by TUM_APISAK. The Geekbench entry shows a 4-core/8-thread processor operating with a base clock of 1.19GHz. Given the "Y" designation, the low clock speed shouldn't be too surprising, as these are ultra-low power mobile processors. Intel's Y-Series typically have a TDP in the 9W range, even lower than the 15-25W U-Series. We're also expecting 12MB of L3 cache (up from 8MB), as we previously reported, and 1.25MB of L2 cache per core.
A SiSoftware entry also was revealed which specifically calls out the Gen12 IGP onboard with 96 execution units (total of 768 shaders). This is a relatively healthy increase over the Gen11 IGP found in Ice Lake (64 CUs). The IGP is also listed with a clock frequency of 1GHz, and support is confirmed for LPDDR4x memory.
While LPDDR4x is used in this particular Tiger Lake-Y processor, the platform also supports LPDDR5 memory (rated for up to 6,400Mbps). LPDDR5 could end up being a big boon for mobile applications, as it is up to 45 percent more power efficiency than LPDDR4x
Tiger Lake-Y supports PCIe 4.0 (a first for Intel), Advanced Vector Instructions 512 (AVX-512), and the Gen12 graphics use Intel's all-new Xe graphics architecture. Also on tap are new Willow Cove CPU cores, which are an upgrade over Sunny Cove in Intel's first 10nm processor: Ice Lake.
In other Intel news, the company apologized earlier this week for lingering production shortages for its legacy 14nm processors.
