The new generation Core processor family, where Intel has introduced a voluminous IPC increase by transitioning to the new architecture, has begun to take its place on the shelves. The chips continued to use the existing LGA 1200 socket.
Rocket Lake processors, which we have been following from the benchmark tests of the blue team for a long time, are on sale. The models brought the increase in IPC.
IPC increase over the years
The 11th generation Core processor family, rising on Cypress Cove cores, offers a 19% increase in IPC compared to the previous generation. Accompanying the processors, the new iGPU with Xe architecture exhibits 50% better integrated graphics unit performance.
A closer look at Cypress Cove
When we look at the key components in the execution section of Cypress Cove cores, it is remarkable that there is a 25% improvement in the allocated bandwidth and port number.
In addition to the 33% increase in the AGU (Address Generation Unit), which saves the total processing capacity of the processor by calculating the addresses used by the processor in the memory, it seems that the increase in the number of the storage unit has paved the way for the new commands added.
Increased L1 and L2 caches
Cypress Cove cores obtained as a result of retrofitting Sunny Cove in processors that continue to LGA 1200 socket contain significant improvements in the cache layout.
While the L1 cache was increased from 32 KB per core to 48 KB with an increase of 50%, the L2 cache per core was updated from 256 KB to 512 KB with a 100% increase. Let’s add that the 16 MB L3 buffer memory is kept constant.
Leading the list of Rocket Lake, Core i9-11900K is an 8-core, 16-thread, 16-thread processor supported with 16 MB of cache. Thanks to the support of DDR4-3200 MHz RAMs on the chip, which can increase up to 5.3 GHz, multitasking will be performed more smoothly.

Thanks to the support of Intel Deep Learning Boost and Vector Neural Network Instructions, processors with hardware acceleration in deep learning-oriented workloads make the process more flexible thanks to new overclocking tools.
In the processors updated with the AVX 2 instruction set, the AVX-512 voltage guard band override and a memory controller that allows for wider timings are located.
In addition to the 11th generation processors, as a result of the increasing competition on the motherboard side, RAMs can now be overclocked in H570 and B560 chipset motherboards.
Rocket Lake processors that come with 20 PCIe 4.0 channels will continue to support Intel Quick Sync Video, while the chips will accelerate the 10-bit AV1 / 12-bit HEVC codecs. In the DMI interface, which was previously updated with PCIe 3.0, the number of channels was increased from 4 to 8.
On the interface side, support for HDMI 2.0 and HBR 3 is offered, while Thunderbolt 4 and Wi-Fi 6e connection possibilities are included. USB 3.2 Gen Finally, data can be transferred faster thanks to its 2×2 (20 Gbps) ports.
