VOV.VN - Mặc dù Samsung sản xuất chip A9 cho Apple, nhưng hiệu năng xử lý mà chip này vẫn còn cao hơn cả Exynos 8890 mới trên Galaxy S7 của hãng.
AnTuTu vừa đăng tải phép thử đánh giá hiệu năng 10 chip xử lý nhanh nhất hiện nay, bao gồm thống kê điểm chuẩn CPU lẫn GPU. Vị trí số 1 trong các phép thử đều thuộc về chip Snapdragon 820 mới nhất của Qualcomm, tiếp theo sau là A9 và Exynos 8890.
AnTuTu lưu ý rằng các con số báo cáo là điểm số trung bình của chip xử lý chứ không phải là hiệu năng cao nhất của chúng. Do biến động trong quá trình sử dụng nên chỉ số trung bình được xem là chân thực hơn thay vì dựa vào kết quả thực tế.
Nếu chỉ số AnTuTu tin tưởng thì Qualcomm cuối cùng đã trở lại với vị trí lãnh đạo trên thị trường chip xử lý. Sau thảm họa 2015 với Snapdragon 810, người dùng sẽ cảm thấy hài lòng khi thấy Snapdragon 820 đã trở lại với vị trí đầu bảng. Tất nhiên đây là hiệu suất thô. Trong khi Snapdragon 810 có hiệu suất mạnh mẽ, nhưng hiệu suất tổng thể của nó bị ảnh hưởng bởi khả năng quản lý nhiệt kém. Snapdragon 820 hiện đang được sử dụng trên một biến thể Galaxy S7/S7 edge, LG G5, Sony Xperia X Performance, Vivo Xplay 5S và Xiaomi Mi 5.
Apple A9 trên iPhone 6S và 6S Plus đã bị đẩy xuống vị trí thứ hai sau khi nếm trải vị trí đầu bảng trong khoảng nửa năm. Phiên bản A9X mạnh mẽ hơn bị vắng mặt vì nó chỉ có mặt trên tablet iPad Pro. Thật kỳ lạ, Exynos 8890 sử dụng quy trình FinFET 14 nm của Samsung vẫn chỉ xếp sau A9. Đó là chip được sử dụng trong một biến thể của Galaxy S7/S7 edge, và sử dụng tại Việt Nam.
Các chip còn lại bị bỏ ở vị trí khá xa so với 3 chip hàng đầu hiện nay. Kirin 950 xếp vị trí thứ 4, nhưng đáng chú ý là vị trí thứ 7 và 9 có sự hiện diện của Snapdragon 652 và Snapdragon 650, những chip tầm trung hiệu suất cao được bán trên một số smartphone hiện nay. Các vị trí còn lại trong top 10 bao gồm Snapdragon 810, Apple A8 và Snapdragon 808.
Qualcomm Snapdragon 652 được xuất hiện trong Vivo Xplay 5, còn Snapdragon 650 được trang bị trên Sony Xperia X.
Về hiệu suất đồ họa, cả ba chip trong top 3 đều ở vị trí giữ nguyên theo thứ tự, với Snapdragon 820 dùng GPU Adreno 530, Apple với PowerVR GT7600 và Exynos 8890 với Mali-T880 MP12, bỏ khá xa các vị trí tiếp theo. Đáng chú ý, Kirin 950 với Mali-T880 MP4 vị đẩy xuống trí thứ 8.
A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.
With integrated graphics you don’t need to buy a separate graphics card.
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.

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.
Using big.LITTLE technology, a chip can switch between two sets of processor cores to maximize performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximize battery life.
Uses HMP
✖Qualcomm Snapdragon 820 MSM8996
Heterogeneous Multi-Processing (HMP) is a more advanced version of big.LITTLE technology. In this setup, a processor can utilize all cores at the same time, or just a single core for low-intensity tasks. This can provide powerful performance or increased battery life respectively.
