Intel Core i9-11900K outperforms Ryzen 9 5950X in benchmarks

Intel Core i9-11900K will be the flagship model of the Rocket Lake-S platform. The eleventh generation of Core processors intended for desktop computers with which the chip giant will compete with the ZEN 3 of AMD.

We already knew that this Core i9-11900K will be an 8-core, 16-thread model with 16 Mbytes of cache. Its base frequency of 3.5 GHz was also known and now we have additional information, such as the 5.3 GHz maximum clock frequency that you can achieve with Thermal Velocity Boost activated, a function that will remain exclusive to the Core i9, while the Core i7 will use Turbo Boost Max 3.0.

The IPC is still fundamental in today’s processor architecture and is one of the things that Intel has not lost to AMD on any platform despite the enormous improvements of this one. Intel has promised a “double-digit” improvement in the Rocket Lake-S platform’s ability to execute instructions per clock cycle.

Perhaps that is why the results that come to us from the benchmarks indicate that this Core i9-11900K outperforms a real monster like the Ryzen 9 5950X. The test has been extracted from the execution in Ashes of the Singularity, a game that is being used as a reference in many tests for its high scalability. In any case, the results (+ 10% in FPS in favor of Intel) are not confirmed nor are they at all conclusive when it comes to establishing which will be the “best” in games.

Otherwise, the new Intel CPUs will use the new Cypress Cove architecture, an adaptation of the Sunny Cove architecture used in Ice Lake chips (10 nm +), to the 14 nm process. This platform is expected to be the last before the final step to 10 nanometers for Intel’s desktop processors, something that has already materialized in those for laptops with the Tiger Lake.

Intel Core i9-11900K: no solo IPC

In addition to IPC, Intel will offer other advantages to this platform through the new 500 series chipset, with main features such as:

  • PCI Express 4.0. At last, Intel would support the latest version of the most important bus for PCs. Intel is expected to offer 20 lanes in total. The CPU will be directly connected and will have 4 additional lanes (x16 for the GPU and x4 for solid-state drives under the NVME protocol). This means that both the dedicated graphics and the SSD storage will be connected directly to the CPU via PCIe 4.0.
  • DMI 3.0 will be upgraded to the x8 link, which means double the transfer speed compared to the current x4. Intel does not set the transfer rate for a new DMI connection, but the current x4 link has a transfer rate of 8 GT / s (3.93 GB / s).
  • Intel Xe. Another important novelty will arrive in the same encapsulation of the CPU and will be the integrated graphics of the latest generation, Gen12, with significant performance improvement, support for HDMI 2.0b and DisplayPort 1.4a, in addition to the technology of synchronization of images Adaptative Sync.
  • Connectivity. The chipset will also bring native support for the latest Wi-Fi 6 and Bluetooth 5.1 wireless connectivity standards, and the most advanced connection ports such as Thunderbolt 4 and USB 3.2. It will support Ethernet LAN 2.5Gb.
  • RAM. The platform will increase the frequency of memory and the maximum capacity supported. It will still be DDR4 (DDR5 will arrive in the next Alder Lake) in a dual channel.
  • Various. In the multimedia section, the chipset will offer support for the 12-bit AV1 / HEVC codec. Intel Software Guard extensions will be removed and their overclocking capabilities will be enhanced.

All motherboards with these Intel 500 series chipsets will use the LGA1200 socket and there is good news for backward compatibility. Rocket Lake-S CPUs will be able to be installed in 400 series motherboards after appropriate BIOS / UEFI updates, while the 500 series will support 10th generation Core processors.

The Intel Core i9-11900K and the rest of the platform models are expected to be presented at CES 2021 for availability in the first quarter of the year.
