MSI GeForce GTX 1660 Gaming X (6GB GDDR5) Graphics Card Review

Over the past few months, we’ve seen a flurry of graphics card being release by Nvidia. Last month it was the GTX 1660 Ti, so I couldn’t believe it when I heard they’ve just announced the GTX 1660 this month. The GTX 1660 uses a GPU that’s very similar to the GTX 1660 Ti, and features Nvidia’s Turing architecture (used on their RTX series), but lacks the essential Tenor and RT cores for ray-tracing. So in other words … both the GTX 1660 Ti and GTX 1660 do not support ray-tracing.

Oh but wait! Nvidia just recently announced that all GTX 10 and 16 series can support ray-tracing via DXR in their next driver update. Confusing? … YES! More on this topic another day. Anyway, let’s get back to the review …

Today, we’ll be taking a quick look at the MSI GeForce GTX 1660 Gaming X (6GB GDDR5) Graphics Card.  The CPU is overclocked to boost speed of 1860 MHz (default 1785 MHz) and comes with 1408 CUDA Cores and 6GB GDDR5 ram, with a memory speed of 8 Gbps on a 192-bit memory bus.



The Gaming X series from MSI does offer some extra features not found on their AMOR or Ventus series. Take for example the brushed metal backplate, Mystic Light Sync RGB lighting and their TWIN FROZR 7 cooling solution. These features will give this card something that mainstream gamers might want.


Here’s a quick comparison between the GeForce RTX 20 series, GTX 1660 Ti and the GTX 1660 (default clock speeds)…

We already reviewed the GeForce GTX 1660 Ti from Zotac and of course MSI. Both graphics card proved to be great performers beating the GeForce GTX 1070 and sometimes even matching the GTX 1070 Ti. So what will the GeForce GTX 1660 give us? 

With a reduced number of CUDA cores and using lower spec GDDR5 ram, I not expecting enthusiast gaming performance. I’m hoping the performance should be about the same as the older GTX 1060. Enough talk. Let’s start by taking a look at the specifications and features in our next page …
