Dark Posted February 8, 2021 Posted February 8, 2021 One of the changes that Intel has made in its Intel Core Gen 11 desktops has been to use a core with a higher IPC than the previous ones, which means an increase in performance in single-threaded tasks. But how does this show up in the benchmarks? Well, it seems that the Core i9-11900K exceeds the most powerful of the Zen 3 in IPC. Although Intel's Gen 12, known as Alder Lake, is also due out this year, its Gen 11 is a game changer as far as Intel is concerned. With the aim of expanding the IPC and with it the performance after generations using the same kernel have changed kernels. With this they can stand up to the AMD Zen 3 and surpass the AMD architecture under certain conditions. Core i9-11900K has better IPC than Zen 3 according to Geekbench 11900K Geekbench11900K Geekbench11900K GeekbenchRocket Lake vs Zen 3 Geekbench ST The Core i9-11900K has been tested three times under Geekbench. All of them with the same motherboard configuration, Gigabyte Z490 AORUS Master, and with DDR4-3600 MHz as RAM. The best single-thread test result was 1905 points, while the multi-thread performance test was 10994 points. The conclusion drawn from these results is that the performance of the Core i9-11900K is 13% faster than the Ryzen 5950X, which is why the Intel CPU is faster in single-thread than the Ryzen 9 5950X. This could be due to the abandonment of a core based on a core derived from Skylake for the eleventh generation of the desktop Intel Core. Let's not forget that in the Rocket Lake-S architecture a new core is used, which brings a 19% increase in the IPC compared to the previous generation. Are you cheating Intel? Speed up CPU One of the peculiarities of the Rocket Lake-S architecture is the fact that a single core can be placed at 5.3 GHz speed exclusively. In other words, Intel uses Single Core Boost, in which only one of the cores is throttled to a higher clock speed than the usual Boost. In the case at hand, the Intel Core i9-11900K has been accelerated to 5.3 GHz speed, so in the benchmark the CPU is running 500 MHz higher than its Boost speed for all cores, which is 4.8 GHz The AMD Zen 3 win in multi-thread to the Intel Core i9-11900K Rocket Lake-S vs Zen 3 Geekbench MT The counterpart is in terms of performance with several threads of execution running in parallel, the reason for this is that Intel has decided to limit the number of maximum cores of its Intel Core Gen 11 based on Rocket Lake-S to only 8 cores, while CPUs and AMD have configurations of up to 16 cores, which allows it to reach 14000 points as seen in the graph. How does this translate to performance? It is difficult to know and it will depend on the code of the software. So there will be programs that will take advantage of more of the greater number of cores and threads of the AMD Zen and others of having a somewhat higher IPC in the case of Intel. It is a shame that the Intel Gen 11 have such high prices, because compared to the Ryzen 7 5800X with the same number of cores it is more expensive, but the Intel product usually brings a number of implicit advantages in terms of support than its users know how to appreciate.
