Exclusive | Full specs and first benchmarks of the NVIDIA GeForce MX330 and MX350 — NVIDIA clings-on to Pascal even in the third iteration

The NVIDIA MX350 is a cut-down GTX 1050 with a 64-bit memory bus.
The NVIDIA MX350 is a cut-down GTX 1050 with a 64-bit memory bus.
We have obtained exclusive information and benchmarks about NVIDIA's latest entry-level dGPUs for laptops — the GeForce MX330 and MX350. While the MX330 is essentially a rebranded MX250, the MX350 is based on the same GP107 chip as the GTX 1050 albeit sporting just a 64-bit memory bus and a lower 25 W TDP.

The NVIDIA GeForce MX-series has traditionally been about having a dGPU that provides a little more muscle power than what traditional iGPUs can offer. Last month, we've reported about NVIDIA's purported plans of introducing the MX330 and MX350 laptop GPUs. Now, we have exclusive first-hand information about the specs of these GPUs and a few preliminary benchmarks. One would expect the next generation MX GPUs to be based on the Turing architecture, but NVIDIA seems to think Pascal is still the way to go in 2020. 

NVIDIA GeForce MX330: MX150 v3?

We get to hear that NVIDIA is once again performing a rebranding exercise with the MX330. The MX330 will have just a 0.8% higher clock speed for the 25W version (N17S-G3) compared to the MX250. Such a small uptick in clocks will be difficult to perceive in benchmarks, which makes the MX330 essentially a rebranded MX250.

Check out our dedicated GeForce MX250 page to get an idea of the kind of performance that can be expected from the MX330.

NVIDIA GeForce MX350: A nerfed GTX 1050 on par with a GTX 960M

Alongside the MX330, NVIDIA will also be introducing the MX350 dGPU. From what we hear, the MX350 is based on the same GP107 Pascal chip as the GTX 1050. However, the MX350 will feature only a 64-bit memory bus and will operate at a lower TGP of 25W. As a result of this, the MX350 offers performance more in line with a GTX 960M than a GTX 1050 itself. 

Here's a quick comparison of preliminary MX350 benchmarks with other NVIDIA GPUs.

Overall, we see that the MX350 is about 23% and 28% slower than the GTX 1050 in 3DMark Time Spy Graphics and Fire Strike Graphics, respectively. That being said, we also see that the MX350 is about 18% faster in Time Spy Graphics and 7% faster in Fire Strike Graphics than the GTX 960M.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
