AMD will be launching its new Ryzen Mobile products in early-2018 at CES, but we also have more exciting news: Radeon Vega Mobile. Radeon Vega Mobile is currently shipping inside of HP's new Envy x360 2-in-1 laptop, and now we know some details about Radeon Vega Mobile.
HP's new Envy x360 features Radeon Vega 8 Mobile graphics and in a surprising move; 256MB DDR4. The system has 8GB of DDR4 in total, and it seems 256MB is dedicated to Radeon Vega 8 Mobile. Radeon Vega 8 Mobile has 8 Vega NCUs, with the Vega 8 GPU clocks at 300MHz base (and should boost up to 1.1GHz)), and the 256MB of DDR4 at 400MHz with 12GB/sec of memory bandwidth.
Inside, HP makes use of AMD's own Ryzen 5 2500U with 'Radeon Vega Mobile Gfx' and ships with Radeon Software 17.7 onboard, not the new 17.11 drivers. HP is stingy with a 1TB mechanical HDD, and no SSD - even for the $799.98 price at Best Buy right now.
It's interesting to see absolutely no HBM2 being used, meaning Vega can and indeed does work without it. Now let's see a discrete graphics card with 8GB of GDDR5.
