Intel's Nova Lake-S Desktop CPUs with 52 cores will require the highest-end 900-series motherboards to display their full performance potential.
Intel Nova Lake 52-Core Desktop CPUs To Display Full Power on Higher-End 900-Series Motherboards, Rest Will Limit Performance & Power
As per new information on Intel Nova Lake-S Desktop CPUs and their respective platforms shared by Jaykihn at X, it looks like only some ultra-high-end tier motherboards will have the prowess to display Nova Lake's full performance potential.
The insider/leaker states that a certain selection of 900-series motherboards, presumably based on the Z990 chipset, will support the full power of the 52-core platform. We know that Intel's top Nova Lake-S Desktop CPUs will house 52 cores in dual compute tile configurations. Each compute tile will feature 8 P-Cores, 16 E-Cores, and there will also be an additional 4 LPE cores on the chip itself.
Early reports suggest that Nova Lake's 52 core chips will sip in over 700W of power with their power limits removed. The early 14+24 SKU PL figures were also revealed yesterday, but those are based on "outdated" specifications, so we will have to wait for official or more updated numbers to know just how much Nova Lake-S Desktop CPUs will consume in terms of power.
On the rest of the Intel 900-series motherboards, the platform itself will limit both power and performance of Intel's 52 Core or Dual Compute Tile Nova Lake-S Desktop SKUs. This could mean that we will see a new tier of motherboards from Intel partners with some hefty VRM designs and beefier VRM cooling. These motherboards will end up being priced very high, but will be the go-to choice for ultra high-end gamers, enthusiasts, and overclockers.
In other news related to Nova Lake-S Desktop CPUs, it is stated that the chips won't feature Intel AMX or Advanced Matrix Extensions. The Intel Nova Lake-S 52-core chips will feature 5 tiles, which include two for the compute tile, 1 iGPU die, 1 SoC die, and 1 platform controller die. We have learned from previous info that the compute dies themselves will measure close 150mm2 and two of these will take up to 300mm2 of package area, but will utilize the same LGA 1954 socket.
That's all the information we have on Intel Nova Lake-S Desktop CPUs for today, but it looks like things are clearing up, and we are getting a more detailed picture of what the new platform and processors are going to look like. Once again, Intel's Nova Lake-S CPUs, along with the 900-series motherboards, are scheduled to launch later this year and will be competing against AMD's Zen 6-based Ryzen offerings, which also offer new architectural and platform innovations, so quite an interesting battle is being brewed up for 2H 2026.
