So sánh Intel i9 9900k vs Amd Ryzen 9 3900x, CPU nào mạnh mẽ
Mới đây AMD đã công bố loạt Ryzen 3000 dựa trên nền tảng kiến trúc Zen2 của mình tại sự kiện báo chí trước Compute 2019 vào hôm nay. Cpu cao nhất trong những cpu thuộc ryzen 3000 series là bộ xử lý Ryzen 9 3900X sở hữu 12 nhân và 24 luồng (ngang với i9 9920x của intel) có TDP rất thấp chỉ 105W, có giá bán tại mỹ là 499 USD tất nhiên là khi về Việt Nam giá sẽ phải cao lên thêm vài triệu. Tại sự kiện computex 2019 AMD lấy cpu i9 9920x của intel ra để so sánh benmark nhưng thực tế giá thành của R9 3900x chỉ ngang i9 9900k nên ở bài viết này mình sẽ so sánh Ryzen 9 3900x vs i9 9900k
Intel Core i9-9900K là flagship của nhóm cpu Core i thế hệ thứ 9.
Đây là CPU chủ lực đầu tiên của Intel và cũng là CPU đầu tiên dòng mainstream có 8 nhân và 16 luồng. Về bộ nhớ đệm, CPU này cung cấp 16MB cho bộ nhớ L3 và sẽ đi cùng với chip đồ họa Intel UHD 620. Xung nhịp cũng là thứ cần phải quan tâm, chúng ta sẽ có 3.6GHz xung nhịp cơ bản và 5.0GHz xung nhịp boost khi chạy tác vụ đơn nhân hoặc hai nhân. 4 nhân boost ở mức 4.8GHz khi 6/8 nhân boost ở mức 4.7GHz.

Đây là mức xung nhịp cao nhấp đã từng thấy trên một cpu 8 nhân trên tất cả các nhân. Tất cả mọi thứ đó điều được hoàn thành dưới mức 95W TDP (Thermal Design Power) vì thế chúng ta cần phải có giải pháp tản nhiệt thật tốt đi cùng với con chip này để đảm bảo nhiệt độ luôn trong ngưỡng cho phép khi render fulload.
Trong khi intel đang rất thành công với cpu i9-9900k 8 nhân 16 luồng thì AMD tung ra cpu cùng phân khúc Ryzen 9 3900x như là một cú tát cực mạnh khiến đối thủ phải té ngửa với thiết lập 12 nhân/24 luồng những tưởng chỉ có trên các dòng CPU hiệu năng cao. Ryzen 9 3900x hiện tại có thể coi là một cpu đa nhân giá cả hợp lý đủ mạnh mẽ để phục vụ công việc và dĩ nhiên là thừa sức chiến tất cả các tựa game từ đây đến nhiều năm sau.
Tất cả các con chip Ryzen thế hệ thứ 3 của AMD đều dùng kiến trúc Zen 2 mới với khả năng cải thiện 15% hiệu suất trên mọi ứng dụng. Dòng chip mới cũng có gấp đôi hiệu suất FLOPS và bộ nhớ cache so với các con chip thế hệ trước. Ryzen 9 3900X có tốc độ cơ bản/ép xung là 3.8GHz/4.6GHz và tổng 70MB bộ nhớ cache. Theo AMD, hiệu suất redner trong Blender của Ryzen 9 3900X cao hơn 16% so với i9-9920X của Intel
