Upon digging some more among device IDs, we’ve come across the ID of the GDDR5 variant, with the ASIC code “GP107-670-A1,” and the silicon is based on the much older “Pascal” architecture, which lacks PCIe gen 4 support. The GDDR6 variant eludes us. This is the SKU which could be based on a newer architecture, given its support for GDDR6 and PCIe gen 4. NVIDIA’s GeForce MX line of entry-mainstream mobile GPUs are built to performance/power targets, and wildly vary with the underlying tech. They’ve been historically a means for NVIDIA to clear inventory of older generation ASICs to notebook manufacturers, who get put the NVIDIA logo on their products, and advertise discrete graphics. Given this, the use of a newer (even unreleased) generation of GPUs comes as a surprise.
