NVIDIA updated the product page of its GeForce GTX 1650 graphics card to make GDDR6 an official memory option besides the GDDR5 that the SKU launched with, back in Q2-2019. NVIDIA now has two product specs for the SKU, the GTX 1650 (G5), and GTX 1650 (G6). Both feature 896 "Turing" CUDA cores, 56 TMUs, and 32 ROPs; but differ entirely in memory configuration and clock speeds.

The GTX 1650 (G6) features 4 GB of GDDR6 memory clocked at 12 Gbps, across a 128-bit wide memory bus, compared to the original GTX 1650, which uses 4 GB of 8 Gbps GDDR5 across the same bus width. This results in a 50% memory bandwidth gain for the new SKU: 192 GB/s vs. 128 GB/s. On the other hand, the GPU clock speeds are lower than those of the original GTX 1650. The new G6 variant ticks at 1410 MHz base and 1590 MHz GPU Boost, compared to 1485/1665 MHz of the original GTX 1650. This was probably done to ensure that the new SKU fits within the 75 W typical board power envelope of the original, enabling card designs that lack additional power connectors. As for pricing, Newegg recently had an MSI GeForce GTX 1650 GDDR6 Gaming X listed for $159.
 
Increased performance at a reasonable price. Sounds like a winner to me.
