Intel’s 14th Gen Meteor Lake processors have been architected with mobility PCs in mind. These chiplet-based CPUs will combine six P-cores (Redwood Cove) with eight E-cores (Crestmont) on the Intel 4 process node. Unlike Alder and Raptor Lake, the desktop lineup won’t scale past the P-core counts of its mobile counterpart. We’re looking at a maximum of 6P cores on both the desktop and notebook parts. This deficit was supposed to be addressed by Arrow Lake, but Intel hasn’t said anything about that in a while.
The target of Meteor is to realize 1.5x+ efficiency compare to the Raptor when it has the same perf. (same core processor, P+E)🧐
About iGPU, I think it maybe will reach almost 2x perf levels. (128EU@2.0+GHz VS 96EU)Originally tweeted by Raichu (@OneRaichu) on February 6, 2023.
According to @OneRaichu, Meteor Lake is targeting an efficiency gain of 50% over Raptor Lake (at the same performance levels). Since power is the primary bottleneck in notebooks, it’d be fair to say that a 30-40% performance uplift for the HK series chips (Core i7-14700HK and i9-14900HK) is very doable.
That said, don’t expect the Core i9-14900HK (with 6 P-cores) to bulldoze the Core i9-13900HK or the desktop-grade 13900HX (8 P-cores). It will be a close call in most multi-threaded workloads. In power-limited, mixed workloads, though, Meteor Lake will truly shine.
In addition to efficiency, integrated graphics performance is also getting a massive upgrade with the 14th Gen Core family. @OneRaichu believes we may get a gen-over-gen uplift of up tp 2x with the tiled iGPUs paired with Meteor Lake. The iGPU tile will be fabbed on TSMC’s 5nm process node for added versatility and flexibility.
