The Hot Chips Symposium in Cupertino, CA had talks about a number of interesting new products today (Monday, 11 Aug 2014), many of which were focused on mobile.
Nvidia discussed their new Tegra K1 mobile processor that targets tablets and laptops. The 32-bit version uses four 2.3 GHz Cortex A15 cores with a 2 Mbyte L2 cache and a Kepler GPU (192 CUDA Cores). It has dedicated accelerators supporting Open GL 4.4, DX12, and CUDA 6, a camera interface, computational photography, four 4 K display drivers, and 3840 x 2160 LCD control.
The Tegra IC from Nvidia
Another version of Tegra K1 uses dual Denver custom 64-bit high performance cores.
AMD talked about their Opteron A1100 processor codenamed “Seattle.” It is a 64-bit ARM based processor with eight Cortex-A57 cores, two DDR3/4 DRAM channels, dual 10G Ethernet ports, eight lane PCIe 6 Gbit/s, eight SATA 3 ports, a crypto coprocessor, and a Cortex-A5 system control core.
SK Hynix discussed their HBM stacked memory module using through silicon vias (TSV). It yields a bandwidth of 256 Gbytes/s – ten to twenty times faster than DDR3, while taking 1/3 the power. The module will have up to 16 die in a package only 80 µ tall. The next generation version will have 4 or 8 Gbytes total in a 4 or 8 die stack.
The Axxis 5516 from Avago
The new Avago Axxia 5516 communication processor also uses ARM Core-A57 64-bit cores – this time 16 of them. The chip also implements the ARM CoreLink CCN-508 Cache Coherent Network. The chip came from Avago’s acquisition of LSI, and is said to yield 3.5 DMIPS/MHZ/core. It has dual DDR3 memory interfaces, a secure system complex, a packet processing engine, and up to sixteen 10GbE XFI/SFI/10GBaseKR ports. Also provided are USB, UART, I2C, SPI, GPI, IEEE 1588, and SyncE. An evaluation board is available.
