As we have already confirmed, GTX 1630 features TU117-150 GPU with reduced CUDA core count to 512. This is even fewer than GTX 1650 (896 cores). Furthermore, the card will have reduced memory bus to 64-bit. This, as we have just learned, is a significant bottleneck for this card.

Despite featuring the same 4 GB GDDR6 memory clocked at 12 Gbps, the bandwidth has been reduced to 96 GB/s, so lower than 6 year old “Pascal” GeForce GTX 1050 Ti, which this model is supposedly replacing (GTX 1050 Ti is now going EOL). The GTX 1650 GDDR6 alone is at least 72% faster, as long as 3DMark synthetic tests are considered.
