Intel 10nm Tiger Lake-U Mobile CPUs Rumored To Be DDR5 RAM Enabled
A next generation Intel "Tiger Lake-U" processor submission for the Eurasian Economic Commission (EEC) suggests the upcoming CPU series will support both LPDDR4X and LPDDR5 memory when it arrives next year. Overall details are rather light, but according to the listing, the unidentified processor is a quad-core chip.
Tiger Lake-U is the eventual successor to Intel's recently introduced Ice Lake family for thin and light laptops. it will be the second mass-produced processor line from Intel to utilize a 10-nanometer manufacturing process, so it will be an iterative bump with presumably faster clocks and improved power efficiency, and apparently LPDDR5 support.
Not to be overlooked, LPDDR5 should offer a nice bump in performance, depending on how it's utilized. While LPDDR4X hits a top speed of 4,266Mbps, LPDDR5 scales to 6,400Mbps. It also consumes less power—up to 45 percent less compared to LPDDR4X, according to Samsung, which makes LPDDR5 memory chips for smartphones.
Granted, memory is not exactly the enemy of battery performance. However, every little optimization helps, and combined with an enhanced architecture and whatever other changes related to power efficiency are in store, Tiger Lake-U could enable longer battery life in laptops.
Tiger Lake-U Leaks Point To More Cache And PCI Express 4.0 Support
In addition to LPDDR5 support, a previous leak pointed to Tiger Lake-U benefiting from a 50 percent increase from L3 cache, going from 8MB to 12MB. That breaks down to 3MB of L3 cache per core on a quad-core CPU (up from 2MB currently).
The cache revelation came by way of a CPU dump posted to Twitter by InstLatX64. According the leak, the quad-core CPU in question also supports Hyper Threading, meaning it has four physical core and four threads to throw at workloads.
Tiger Lake-U is also said to feature support for Advanced Vector Instructions 512 (AVX-512), same as with Sunny Cove. Intel touts AVX-512 as being able to bolster a wide range of workloads and usages, such as scientific simulations, financial analytics, artificial intelligence, deep learning, 3D modeling and analysis, image and audio/video processing, cryptography, and data compression.
Finally, yet another previous leak suggests Tiger Lake-U will support PCI Express 4.0. If true, this would pave the way for faster performance in some areas, such as storage—a spattering of PCIe 4.0 SSDs are rated to transfer data at up to 5,000MB/s.
