GPD Win2 updating 8100Y version 1. Except CPU,SSD also upgrade to 256GB,price is same as 128GB version. 2. Heat dissipation improved. The main board of 7Y30 version is designed with dual layers, power control IC and SSD are overlay together, heat will stay at right hand position and can't dissipate out, then it's will be overheat when you run AAA game with high TDP. So we have redesigned whole main board, we have staggered Power IC and SSD, disperse heat to solve local overhe...ating, you don't need worry about suddenly shut and can't boot during charging and playing. 3. Raised the speed of SD card writing and reading, A2 TF card was compatible. The bus rate of TF card is 833Mbps, the bus bandwidth is 104MB/s. Some A1 TF card say they can reach to 100MB/s with reading, 80MB/s with writing, but in fact just 70MB/s reading and 50MB/s writing. The theory speed of A2 would be: 160MB/s reading and 90MB/s writing. 4. Support 5V charge, All none PD charger and power bank are all compatible. Unless you are in urgent, we still suggest you use default charger, 5V/2A or 3A would be not enough when your unit is on, because power need supply to main board and battery as well. 5. Improved the audio, add independent power amplifier IC. 7Y30 version used default power amplifier, not good as well. New Win2 will give you high fidelity sound quality, better gaming experience See More
