Back from the grave, Nvidia has resurrected the GTX branding for its newest graphics card – the GTX 1630. Calling this ‘new' is somewhat of a stretch however, as GTX 1630 is simply a cut-down version of the GTX 1650 that launched three years ago on the Turing architecture. What sort of performance can we expect from this product? That's what we will find out today…
While the graphics card market had been in turmoil for almost the last two years, things are quickly returning to normal following the crypto crash and a steep drop in demand for GPUs. It is amidst that backdrop that Nvidia has announced the GTX 1630, although this GPU has launched with next to no fanfare and could easily have been missed.
Given the name, it is fair to assume the GTX 1630 is a successor to the GT 1030, and we certainly won't be expecting too much in terms of gaming performance from this card. With UK prices starting at £179.99 however, the GTX 1630 will have to really surprise us to justify that price point…

First let's take a quick look at the specs. As a cut-down TU117 GPU, the same silicon that was originally used for the GTX 1650, the GTX 1630 sports a total of 8 streaming multiprocessors (SMs). Each SM houses 64 CUDA cores, giving a total of just 512.
We also find 32 texture units and 16 ROPs, while rated boost clock comes in at 1785MHz. Today we are testing the Palit Dual model, which does not ship factory overclocked.
As for the memory configuration, 4GB GDDR6 is standard for the GTX 1630, operating at 12Gbps. Over an extremely narrow 64-bit interface however, that delivers 96GB/s bandwidth, a reduction of 25% compared to the GDDR5 GTX 1650.
Lastly, despite all of its cutbacks, GTX 1630 is still rated at 75W total graphics power, the same as the GTX 1650. This certainly seems odd based on the specs, but we are using our updated GPU power testing methodology in this review, so read on for our most detailed power and efficiency testing yet.
