AMD Ryzen Processors

On the performance side, the Zen microarchitecture represents a leap in core execution capability versus AMD’s previous desktop designs. Notably, the Zen architecture features a 1.75X larger instruction scheduler window and 1.5X greater issue width and resources; this change allows Zen to schedule and send more work into the execution units. Further, a new micro-op cache allows Zen to bypass L2 and L3 cache when utilizing frequently-accessed micro operations.


A high-performance engine requires fuel, and the Zen architecture’s throughput characteristics deliver in this regard. Chief amongst the changes are major revisions to cache hierarchy with dedicated 64KB L1 instruction and data caches, 512KB dedicated L2 cache per core, and 8MB of L3 cache shared across four cores.


Beyond adopting the more power efficient 14nm FinFET process, the Zen architecture specifically utilizes the density-optimized version of the Global Foundries 14nm FinFET process. This permits for smaller die sizes and lower operating voltages across the complete power/performance curve.


Scalability in the Zen architecture starts with the CPU Complex (CCX), a natively 4C8T module. Each CCX has 64K L1 I-cache, 64K L1 D-cache, 512KB dedicated L2 cache per core, and 8MB L3 cache shared across cores. Each core within the CCX may optionally feature SMT for additional multi-threaded capabilities. More than one CCX can be present in a Zen-based product.

AMD A320 Chipset

AMD’s AM4 Platform currently consists of 5 chipsets. That’s the X370, A/B350, A320, X300 and the A300 chipset in chronological order.

X370 B350 A320 X300 A300
USB 2.0 6 6 6  N/A N/A
USB 3.1 G1 6 2 2  N/A N/A
USB 3.1 G2 2 2 1  N/A N/A
SATA 4 2 2 N/A N/A
SATA Express
(2x SATA III or 2x PCIe 3.0)
2 2 2 N/A N/A
PCI-e 2.x 8 6 4  N/A N/A
SATA RAID 0, 1, 10 0, 1, 10 0, 1, 10 0, 1 0, 1
Multi-GPU Yes No No Yes No
Overclocking Yes Yes No Yes No

The A320 sits flush next to the B350, dubbed by AMD as an essential computing chipset. It supports memory overclocking, has plenty of IO options but doesn’t support multi-GPU technology.

Packaging and Accessories

The ECS A320AM4-M3 being a part of the Durathon 2 series of products, comes in a new color box design. We’ve seen this at COMPUTEX 2017 and ECS did not disappoint to freshen up.

The board comes with a few bundled accessories which is not surprising for a budget oriented motherboard.

Design, Build and Connectivity

The ECS A320AM4-M3 wont win any awards when it comes to aesthetics, featuring a brown PCB. Coating it with matte black should make it a little more pleasing but this is a budget oriented motherboard after all.

ECS A320AM4 Review 3

Layout wise, we are looking at a motherboard with a safe one. The majority of main headers and power connectors are located at accessible areas, together with the fan headers. There are no VRM heatsinks so it’s better to get a down draft CPU cooler extra protection. The stock AMD cooler will do.

ECS A320AM4 Review 8

The back of the board shows us the PCI-E slot’s electrical properties. From top to bottom, we have a x16, x4, and x1 including the M.2 into the equation.

ECS A320AM4 Review 9

The audio components are separated from the rest, so we’re expecting good levels here as far as noise is concerned. As for the usual headers, we have plenty at the bottom together with the 3rd fan header.

ECS A320AM4 Review 4

Storage options this side of the board are provided by 4 native SATA ports and dual USB 2.0 headers. All of these, together with USB 3.0 header are powered by the A320 chipset.

ECS A320AM4 Review 5

Back panel options are excellent for the price. USB 3.0 ports are plenty and we’ve got a PS/2 port for legacy devices as well. Display options are excellent too. As for the audio, you’ll get 3 jacks – which is more than enough for most.

ECS A320AM4 Review 7


The ECS A320AM4-M3 features an 80’s vibe UEFI. There are 2 modes; the default and the Advanced. The former is the one you see below, while the Advanced is more tuned with the legacy BIOS interface.


Mouse navigation is not its strong point featuring a low sensitivity. Keyboard navigation on the other hand is alright.


If you’re looking for CPU overclocking options, this one doesn’t have any as with any A320 chipset motherboards. However, you can overclock your DIMMs. Just enable Memory Clock Control, set the Clock Speed and everything else in auto.


ECS had the board bundled with few applications. They are mostly drivers with the exception of eBLU, eDLU and eSF.

Test Setup

The system performance shall be evaluated by various benchmarking tools and applications. We are testing this system with the high-performance settings enabled at the OS, with the default UEFI configuration. Background processes such as anti-viruses and third-party applications are disabled as well. Outlined below are the applications and benchmark tools for reference:

CPU COOLER Cryorig C1 Top Flow
MEMORY KIT Crucial Ballistix Tactical DDR4 @ 2666MHz 2x4GB
OPERATING SYSTEM Microsoft Windows 10 Pro


  • Super PI – 32M Calculations
  • wPrime – 32M and 1024M Calculations
  • AIDA64 Extreme Edition – Memory Benchmark


  • GIMP – 7 MB worth of image processing
  • HandBrake – 150 MB MP4 to H.264 video encoding
  • WinRAR – Internal benchmark tool


  • AS SSD – Storage performance
  • RightMark Audio Analyzer – Audio performance
  • AIDA64 Extreme Edition – Power consumption
  • NetIO-GUI – Network Performance


The AIDA64 System Stability Test uses a 64-bit multi-threaded stress testing module to drive the system to its limits. Power readings are recorded with a watt-meter.

Power consumption is top notch which is expected for a budget oriented mATX motherboard.

CPU and Memory

Super PI is a single-threaded program that calculates pi to a specified number of digits after the decimal point. It is a widely used benchmark within the industry.

The AIDA64 Memory Benchmark measure the data transfer bandwidth and latency of the system memory. We are measuring the latency on this benchmark.

ECS A32AM4 M3 Benchmarks 4

Good performance output from the board here. Performance difference from the other chipsets are not that huge.


GIMP or GNU Image Manipulation Program, is a free and open-source image editing tool. A 7 MB worth of images is be processed and converted to gauge the system performance.

HandBrake is a free video encoding tool that supports a wide variety of media codecs. A 150MB worth MP4 video is converted using the H.264 codec to gauge the system performance.

ECS A32AM4 M3 Benchmarks 7

WinRAR is a file archive utility that can create, view and unpack numerous archive file formats. The software’s built in benchmark tool is utilized to gauge the system performance.

The productivity performance results of the motherboard is synonymous with our synthetics. Nothing is out of place.


AS SSD is a storage benchmarking software widely used throughout the industry. On this test, we are using its scoring system to evaluate our Crucial BX200 SSD’s performance using the system’s native SATA controller.

ECS A32AM4 M3 Benchmarks 8

SATA III performance is great but the Intel chipsets still holds the best interface record for our SSD.


The RightMark Audio Analyzer (RMAA) is a tool designed to test the quality of audio devices. We used a sampling rate of 24-bit at 48000Hz for the loopback test. We are essentially testing the quality of the line-in and line-out of the audio solution.

ECS A32AM4 M3 Benchmarks 9

The noise level performance is generally very good at -89.8dBA. Frequency response is almost flat with a small roll-off at 20Hz.


The NetIO-GUI is a good application to test any network’s performance. The LAN round trip time is our concern here, checking out latency anomalies if there are any. The client and server are connected on the network via Cat5 cables using a 100Mbps router.

ECS A32AM4 M3 Benchmarks 10

RTT performance is nothing to worry about with <1ms of latency on any packet sizes tested.


The ECS A320AM4-M3 is a true value oriented motherboard that packs quite a punch. While CPU overclocking is no where to be found, it excels at providing a comparable performance with the B350 and X370 chipsets. *This is a limitation of the A320 chipset but nonetheless, memory OC is supported.

Build quality and layout wise, the motherboard is more than capable of housing the usual USB devices we’ve got and there are plenty of headers for expansion. The addition of an M.2 slot for the 3100 Pesos pricepoint is also ideal for those who are looking for a simple AM4 motherboard that supports the PCI-E x4 interface.

The ECS A320AM4-M3 is an excellent value oriented motherboard. Simply nice for the price.
