Mac du cong nghe 50nm se khong duoc Samsung san xuat dai tra truoc nam 2008, song su kien nay cho thay cac hang chip cung dang tich cuc chuan bi cho "buoc qua do" len Vista. Hang nghien cuu Gartner du doan rang nguoi dung se chuyen sang dung Vista mot cach "tu tu", va chip nho chinh la yeu to quyet dinh trong qua trinh nay, tu ca phia nguoi tieu dung lan cac hang san xuat PC. "He dieu hanh khat bo nho" Microsoft da cong bo hai bo tai lieu Huong dan ky thuat ve he dieu hanh moi Vista cho cac hang PC. He thong nao co DRAM 512 MB se duoc gan logo Windows Vista Capable PC trong khi nhung he thong 1GB se duoc dan logo Windows Vista Premium Ready. Trong hai he thong thi Windows Vista Premium Ready, theo loi Microsoft, se mang lai nhung trai nghiem "chua tung co" cho nguoi dung, bao gom duyet truoc thumbnail thoi gian thuc, chuyen doi task 3D... Voi viec DRAM phai co dung luong it nhat 512 MB moi duoc xep vao loai tuong thich voi Vista, cac hang may tinh da ruc rich dap them bo nho cho nhung san pham sap ra mat. "Phan lon may tinh "Vista-Ready" se co DDR2 dung luong 1GB, trong khi may tinh dan dung la 2 GB", ong Ben Tseng, pho chu tich hang san xuat DRAM ProMOS Technologies cua Dai Loan cho biet. Cuoc chay dua tang dung luong DRAM giua cac hang se day muc DRAM trung binh tren moi dau may tinh len 900MB trong quy IV nam nay. Lap lo kha nang DRAM khan hang? Ro rang DRAM dang la linh kien then chot trong viec ung dung Vista. Neu nhu nguoi dung do di mua may tinh Vista voi quy mo lon, rat co the thi truong DRAM dung luong lon se khong dap ung noi. Nhieu nam tro lai day, cac hang chip nho hau nhu chi tap trung vao viec san xuat bo nho flash NAND (von dang rat an khach do nhu cau cao danh cho cac san pham iPod, may chup anh so, camcorder....) ma quen mat DRAM. Chi toi khi gia DDR2 lien tuc tang cao trong may thang nay, ho moi bat dau "giat minh" ngo lai. Nhung du sao thi cung da muon, vi thuong thi xay mot nha may DRAM moi phai mat it nhat la hon mot nam, cong them kinh phi hang ty USD.
