Hôm nay ông bạn tôi có buzz Skype mà hỏi rằng nên mua máy tính Chip CPU I3 hay Chip CPU G thì hay hơn ? Nhân tiện cũng post luôn bài tư vấn cho các bạn chọn !
Đôi khi Chip G tốt hơn chip I3
CPU dòng I tốt hơn
Chip CPU intel dòng I có từ I3 tới i7, với nhiều mã hàng và chủng loại, xung nhịp cũng như hệ số nhân, nhìn chung chip dòng I luôn tốt hơn chip dòng G ở cái xử lý đa luồng, công nghệ mới hơn và chạy nhanh hơn ! Thường thì xung nhịp sẽ cao hơn dòng G cùng số !
CPU dòng G rẻ hơn
Hiệu năng không hơn là bao nhiêu nếu bạn so sánh chip I3 với G, tôi lấy ví dụ như chip G3220 vs I3220, có nhiều điểm Chip G tốt hơn rất nhiều !
Với khoảng giá 2 triệu 8 cho Chip I, với chip G rẻ hơn rất nhiều với giá 1 triệu 2, rõ ràng lựa chọn chip G là rất kinh tế cho các máy phổ thông !
I3 nhiều luồng hơn G
Dòng G chỉ có hai nhân, với hai luồng xử lý, trong khi dòng I3 có tới 2 nhân nhưng lại 4 luồng xử lý, nếu xử lý đồng thời một tác vụ, rõ ràng dòng I sẽ xử lý xong trước, ví dụ như convert một video hay dàn dựng phim !
Dòng G và I3 đều dành cho máy tính phổ thông
Các dòng máy tính phổ thông đều có thể dùng chip G và chip I3, tôi luôn ưu tiên tư vấn sử dụng dòng G cho các máy tính cơ bản, không dùng các công việc nặng nhọc, và nếu có đánh game thì rõ ràng dòng G vẫn tải ngon lành, kể cả các tựa game tương đối nặng, nếu rất nặng và sử dụng nhiều đồ họa, chỉ cần lắp thêm card màn hình là ngon lành !
Dòng G có công nghệ gần như dòng I
Dòng G và dòng I đều sử dụng các công nghệ gần tương tự nhau, ngoài ra còn cùng chung một socket với nhau, cùng sinh ra trong một năm, những kí tự tương đương với nhau, ví dụ I3 2120 vs G2120, thậm chí dòng G còn ra sau hơn một chút so với dòng I cho nên các dòng G cùng số với I sẽ tốt hơn I !
Dòng G tốt cho máy văn phòng
Nhờ tiết kiệm tiền bạc hơn so với I, dòng G sẽ thích hợp cho các máy tính văn phòng, hãy tưởng tượng bạn tiết kiệm được cả chục triệu đồng khi sắm cho công ty của mình các máy tính dòng G.
Và, trong trường hợp bạn mua cho văn phòng, hãy chọn dòng chip G, còn nếu bạn muốn đánh game hay xử lý ảnh, video thì nên ưu tiên cho dòng I3, chúc các bạn vui vẻ !
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
The thermal design power [TDP] is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.
If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.
Peripheral Component Interconnect Express [PCIe] is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. Newer versions can support more bandwidth and deliver better performance.
A higher transistor count generally indicates a newer, more powerful processor.
Performance
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores [processing units]. It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
More threads result in faster performance and better multitasking.

When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.
A larger L2 cache results in faster CPU and system-wide performance.
A larger L3 cache results in faster CPU and system-wide performance.
A larger L1 cache results in faster CPU and system-wide performance.
More data can be stored in the L2 cache for access by each core of the CPU.
More data can be stored in the L3 cache for access by each core of the CPU.
