AMD A9 Processor Review: General Info, CPU List, Advantages

What Is AMD A9 Processor?

AMD A9 Processor refers to the 7th and some 6th generation of AMD (Advanced Micro Devices) Accelerated Processing Unit (APU), which is the marketing term for a series of 64-bit microprocessors from AMD and is designed to act as a CPU (Central Processing Unit) and GPU (Graphics Processing Unit) on a single die. APUs, formerly called Fusion, are general-purpose processors that feature integrated graphics processors (IGPs).

Therefore, AMD A9 processor can also be called AMD A9 CPU or even AMD A9 GPU.

AMD A9 Processor List

What are the AMD A9 series processors? There are only three. Just see them in the following table.

	AMD A9-9425 Processor	AMD A9-9420 Processor	AMD A9-9410 Processor
Number of CPU Cores	2	2	2
Number of GPU Cores	3	3	3

Platform	Laptop	Laptop	Laptop
Launch Date	Q2 of 2018	Q2 of 2017	Q2 of 2016

Tip: Actually, there is an AMD A9-9420e processor, which is released in Q2 of 2018. It is equipped with AMD Radeon™ R5 Graphics and 5 computer cores (2 CPU cores + 3 GPU cores). AMD A9-9420E’s clock speed is 2.6 GHz and it is used on the laptop too.

AMD A9-9425 Processor Review

Now, let’s take a review of the most popular model of the AMD A series processor, the AMD A9-9425.

AMD A9-9425 vs Other A9-Series CPUs

As the newest version of the AMD A9 series processors, A9-9425 equips with the most advanced components of the whole family and functions the best among the family members. As you can compare it with the others in the above table, it stands out nearly on all aspects if there is a difference.

How about comparing AMD A9-9425 CPU with other brands of CPUs like Intel? What are the differences and which one is better? Below will take

AMD A9-9425 vs Intel Core i5-8265U

Still, we will rely on a table to show the differences between AMD A9-9425 and Intel Core i5-8265U.

	AMD A9-9425	Intel Core i5-8265U
GPU Clock Speed	800 MHz	300 MHz
Directx Version	12	12
OpenGL Version	2	2
CPU Speed	2 x 3. 1 GHz	4 x 1.6 GHz
CPU Threads	2	8
Turbo Clock Speed	3.7 GHz	3.9 GHz
L2 Cache	1 MB	1 MB
L1 Cache	196 KB	256 KB
RAM Speed	2133 GHz	2400 GHz
Memory Channels	1	2
Memory Version	DDR4	DDR4

From the above comparison, the two models of processors have advantages over the other.

AMD A9-9425 is better for:

GPU clock speed
More L2 cache per core (0. 5MB/core vs 0.25MB/core)
Having dynamic frequency scaling
Having FMA4

Intel Core i5-8265U is better for:

CPU speed
RAM speed
CPU thread
Memory channel
Turbo clock speed
Using multithreading
