Always On, Always Connected
At Computex this week, Qualcomm unveiled its second generation of processor platform for Windows PCs, the Snapdragon 850 Mobile Compute Platform. Along with the new branding that attempts to separate the solutions provided for mobile phones from PCs, the chip gets some interesting and necessary upgrades from the currently shipping Snapdragon 835.
Qualcomm has been building and defining the segment and role of the Always On, Always Connected PC since it first started talking up its move into Windows 10 territory in 2017. The company still believes that longer battery life, an always connected device that is instant on, and a fast and constant wireless LTE connection are ingredients for a solution that consumers want and that is not being addressed by Intel or AMD today. I tend to agree with them, though it is a fair belief that the first generation devices still lack in the performance department; enough to warrant some negative reviews from media.
In favor of Qualcomm’s direction, the PC users demand for cellular data connections and extremely high battery life appear to be growing. As Intel struggles with its processor and process technology development, Qualcomm is able to iterate and improve on its performance and efficiency with its partners Arm and TSMC helping along the way. Qualcomm’s own research shows that awareness and “willingness to pay” for these features has increased year-on-year.
Technically, the Snapdragon 850 uses the same core IP as SD 845 SoC for smartphones. That includes the Kryo 385 CPU, Adreno 630 GPU, Spectra 280 ISP, Hexagon 685 DSP/vector processor (a new naming shift), and the Snapdragon X20 LTE modem. The difference in naming is mostly to separate the chip options for mobile PCs from mobile phones and tablets, though there are modest performance changes because of higher clock speeds on the Kryo CPU. (2.8 GHz on the SD 845, 2.95 GHz on the SD 850.)
Compared to the currently shipping Snapdragon 835, the new 850 will offer 30% better performance, 20% better battery life, and even 20% faster peak Gigabit LTE speeds, up to 1.2 Gbps. Both the CPU and GPU integrations definitely faster with the SD 850 compared to the older 835, each seeing architectural changes as well as clock speed increases. That 30% performance increase estimate is evenly weighted across the two primary processing blocks, 30% each.
Efficiency is also improved on each sub-core, giving Qualcomm the ability to lower idle and active power draw, increasing the battery life estimates of the total platform. Considering this is one of the areas where Qualcomm already had a lead over the best Intel options on the market, this is noteworthy, and something that likely concerns Intel.
