It has been rumored that Raptor Lake and Alder Lake have similar performance core (Performance Core) and Efficient Core (Efficient Core) designs. The former will be changed from the Golden Cove architecture to the Raptor Cove architecture, while the latter will follow the current Gracemont architecture, using the same Intel 7 process manufacturing.
Recently, Twitter user @InstLatX64 found in Intel’s microarchitecture analysis document that the Raptor Cove and Golden Cove architectures are basically the same, and no changes have occurred. Although the current leaked benchmark results show that Raptor Lake has improved both single-core and multi-core performance compared to Alder Lake, due to the same underlying architecture, there will be no significant improvement in IPC. It is understood that Raptor Cove is mainly different in the design layout.
Currently, in the Geekbench database, there are already Core i7-13700K with DDR4-3600 and DDR5-5200 respectively. The corresponding motherboards are ASRock’s Z690 Steel Legend WiFi 6E and Z690 Steel Legend WiFi 6E/D5. The difference is only in memory support. When paired with DDR5 memory, although the single-core score dropped slightly, the multi-core score increased by nearly 20%.
Coincidentally, the Core i5-13600K also has similar test results. When paired with DDR5 memory, the multi-core score is improved by 11%. The comparison results of the two different processors seem to show that Raptor Lake will support DDR5 memory better.
