On this performance review, we are taking a look at the AMD Ryzen 5 1600X CPU. A multi-threaded AM4 processor featuring 6-cores and 12-threads operating at 3.6 GHz base clock. The R5 1600X is at the middle of the pack of the Ryzen Family and is slated to compete with the non HEDT Core i7 desktop CPUs.

AMD dubs the 1600X as the world’s fastest 6-core, 12-thread desktop processor. It is a bold claim and we are going to check if it is really a fast one!

AMD Zen x86 Architecture

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 B350 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. What we have here is the GIGABYTE AB350 Gaming 3 motherboard, featuring the AMD B350 Chipset.

The B350 sits flush next to the enthusiast level X370, dubbed by AMD as a flexible performance geared chipset. It supports overclocking, has plenty of IO options and supports multi-GPU if enabled by AMD’s board partner. Such is the GIGABYTE AB350 Gaming 3, our test system’s motherboard for the Ryzen 5 1600X CPU.

The AB350 Gaming 3 is the top of the line B350 chipset motherboard from GIGABYTE. It is a standard ATX motherboard, supports 64GB of 3200MHz memory and AMD’s 2-Way CrossFire technology. The Gaming 3 also features RGB customization with a flushed audio and full support for USB 3.1 standards.

Test Setup

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

The system power consumption stays true to the improved efficiency of the Ryzen CPUs. Compared to other systems though, the Ryzen 5 1600X features a higher power consumption when the chip is idling. This could be due to the CPU, motherboard, the cooler or a combination of the three. As for the Wraith Spire, we got a maximum reading of 72°C; While at a lower power state, the CPU stays cool at 39°C. Pretty decent performance from the Wraith Max cooler I must say.

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 and stress test within the industry.

The AIDA64 Memory Benchmark measure the data transfer bandwidth and latency of the system memory. On this benchmark, we are measuring the memory kit’s latency.

AMD Ryzen 5 1600X Review 5

Single-threaded performance courtesy of Super PI tells us that the Ryzen 5 1600X is 13% slower than the Core i5 6600K. At multi-threaded benchmarks though, the Ryzen 5 1600X is 49% faster. A way better multi-threaded performance over a slightly lower single-threaded performance is an indication of a well-rounded performance. Memory latency could be better though.


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.

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.

AMD Ryzen 5 1600X Review 6

Real world benchmarks shows us that the Ryzen 5 1600X is a multi-threading monster for its price. GIMP results are still geared towards Intel’s chips, while WinRAR and Handbrake shows exceptional results for the AMD hardware.


Battlefield 4 is Electronic Art’s popular First Person Shooter, running on the Frostbite 3 game engine developed by DICE. It utilizes the DirectX 11 and the Mantle API.

The Witcher 3: Wild Hunt is CDProjekt RED’s award-winning Action Adventure RPG. The Witcher 3 utilizes the REDengine 3 with DirectX 11 support.

AMD Ryzen 5 1600X Review 11

The Ryzen 5 1600X CPU’s gaming performance is slightly behind the pack. Notice that the Ryzen 5 and Ryzen 7’s gaming performance at Witcher 3 an DiRT are similar.


The AMD Ryzen 5 1600X is simply put, an excellent CPU for its worth. Scratch the Ryzen 7 1800X, get this one instead. Performance is just surprisingly good for a $229 / 12500 Peso chip. Again, that’s 13% less single-threaded performance difference for a 31-49% trade-off at multi-threaded benchmarks compared to its slightly pricier Intel counterpart.

Gaming performance wise, Intel’s Core i5 chips are still the kings, but future proofing is what PC is all about. Future titles could benefit for more cores and while we are at it, more cores means you could put less stress on your PC’s individual cores. That should help you for – let’s say, gaming while doing something else. You could be streaming, switching between apps, or even games.

The Ryzen 5 1600X is truly what a sub $250 CPU should be. It has a good single-threaded performance, while its multi-threaded performance puts the icing to the cake. If you are looking forward to build a gaming system or a mid-range power house, then you should definitely put this one on your wishlist.

AMD Ryzen 5 1600X


The AMD Ryzen 5 1600X is a beastly 6-core 12-thread AM4 CPU. An impressive mid-range product that features an excellent multi-threading performance. For $229, this CPU is hard to beat.
