Intel Core i5-11400 Nearly 40% Faster than the 10400 in Single-Threaded Workloads

Intel’s Core i5-x400 and the x400F were easily the most popular CPUs over the last couple of generations. The Core i5-9400F and the i5-10400 were the best-selling CPUs in many markets including Germany, China, India, and most online-based US retailers. As such, the successor to the latter will be crucial to Intel’s volume sales this year, and it shows. The chipmaker has enabled memory overclocking with the lower-end B560 and H570 motherboards while also supporting the 11th Gen parts on the existing H470 and Z490 boards.

In terms of raw performance, we’re looking at a performance gain of as much as 40% with the Core i5-11400 (compared to the 10400) in lightly threaded workloads such as gaming, word/excel processing, browsing, and most mundane applications. An IPC increase of 15-20% along with a lower cache latency (higher bandwidth) are the primary contributors to this gain other than higher boost clocks.

Before coming to a conclusion, it’s important to have a look at the detailed performance metrics across various kinds of workloads as GB5 attributes a notable weightage to Crypto which is largely useless for most consumers.

As you can see, the majority of the gain does indeed come from a significantly higher crypto score. However, the integer and floating-point scores do get a healthy improvement with Rocket Lake-S, with an approximate gain of 30% in terms of single-threaded performance. Overall, you can easily expect a generational increase of 20-30% with the 11th Gen lineup, if not more.
