Leaker reveals two new Qualcomm Snapdragon X Plus and Snapdragon X Elite chipsets with specifications detailed

The dust has now settled on Qualcomm's Snapdragon X series launch event, during which it revealed four chipsets. Incidentally, it seems that the Surface Pro 10 has already popped up running Qualcomm's sole official Snapdragon X Plus chipset, codenamed X1P-64-100. Meanwhile, the Surface Laptop 6 appears to be in development with at least the X1E-80-100, Qualcomm's mid-tier Snapdragon X Elite variant between the X1E-78-100 and X1E-84-100.

However, Kamila Wojciechowska asserts that Qualcomm has designs on offering a second Snapdragon X Plus chipset codenamed X1P-42-100. Allegedly, the Snapdragon X Plus (X1P-42-100) contains eight Oryon CPU cores, compared to the six of the X1P-64-100. However, the X1P-42-100 lacks any Oryon efficiency cores, of which the X1P-64-100 has four. While those specifications suggest that the X1P-42-100 would be more powerful than the X1P-64-100, the former supports fewer PCIe lanes than the latter:

• X1P-42-100 - 4+4 PCIe 4.0 lanes, 2+2 PCIe 3.0 lanes
• X1P-64-100 - 8+4 PCIe 4.0 lanes, 2+2 PCIe 3.0 lanes

Additionally, the X1P-42-100 is said to be limited to 4K/30 FPS encoding and 4K/60 FPS decoding, compared to 4K/60 FPS encoding and 4K/120 FPS decoding for the X1P-64-100. Unfortunately, many other details about the X1P-42-100 remain unknown for now, including its CPU clock speeds and GPU information.

Separately, Wojciechowska reports that Qualcomm has a server-grade chipset in development codenamed 'SD1'. According to the same leaker, SD1 contains 80 Oryon cores on a 9470-pin LGA socket measuring 98.0 x 95.0 mm. Furthermore, SD1 is rumoured to utilise TSMC's 5 nm (N5P) node, plus 16 channels of DDR5-5600 RAM, 70 PCIe 5.0 lanes and support for two chipsets running simultaneously. Wojciechowska also mentions that SD1 integrates Compute Express Link (CXL) 1.1; other details about Qualcomm's return to server-grade processors are unclear at this stage, though.
