Razer announces the Razer Core X Chroma on the 16th April 2019. It is a minor upgrade from the Razer Core X which retails for S$449.90 in Singapore and it is frequently out of stock.

Razer Core X Chroma retails for S$599, making it S$150 more expensive than the Razer Core X.

Razer Core X and Razer Core X Chroma are the most value for money eGPU in the market. The other eGPU I was looking at is the Sonnet eGFX Breakaway Box.

Between Razer and Sonnet, I ended up choosing Razer because it is cheaper, sleeker, and overall the design looks better.

Between Core X and Core X Chroma, I chose the Core X Chroma. For just S$150 more, you get four USB 3.1 Type-A Ports, a Gigabit Ethernet Port, 50W of additional power, and a dual-chip design on the Thunderbolt 3.

The power supply is capable of delivering up to 100W of power to charge your laptop via USB-C PD. Despite having an additional 600W of power, it only supports graphics cards up to 500W. The other 100W goes to powering the USB-A ports, Ethernet port, and Chroma lighting.

According to Razer, the dual-chip design will handle both graphics and data (4x USB 3.1 Type-A Ports, 1x Gigabit Ethernet Port) through a single Thunderbolt 3 cable to your laptop.

The Thunderbolt 3 cable that is included in the packaging is rather short at 0.5m.

One of the downsides of using it for Mac is the Razer software. Razer Synapse 3 is available only on Windows. The legacy Razer Synapse 2 which supports Mac doesn’t work with the Razer Core X Chroma and unlikely it will. So we can only hope Razer will port Razer Synapse 3 to Mac soon!

Without Razer Synapse 3, you just can’t configure the Razer Chroma colors. Everything still works per normal on the Mac and it is not a deal breaker.
