Core i7-11700K Performs Worse in Video Games Than Predecessor

Editors of AnandTech tested Intel's latest CPU, Core i7-11700K, which will debut on the market on March 30. It seems that in video games the processor performs worse than Intel's last year's CPU.

IN A NUTSHELL:

  1. Tests by AnandTech editors indicate that the Core i7-11700K is slower in games than last year's Core i7-10700K;
  2. In most applications the unit performs worse than the Ryzen 5800X;
  3. The CPU also draws significantly more power than its predecessor and the aforementioned AMD processor.

The first review of Intel's new Rocket Lake processor, the Core i7-11700K, has appeared on AnandTech. The tests are quite surprising - it seems that in video games the discussed CPU is often slower than both the AMD Ryzen 7 5800X CPU and last year's Intel model, the Core i7-10700K. The differences generally reach a few frames per second.

In some titles the new processor loses to its older brother in every test, while in others it performs worse, the more we increase the details. According to AnandTech's editors, the reason is the latency on the L3 cache, which is higher than in Core i7-10700K (28-30 versus 18-24 nanoseconds).

That's not all, though, as the new processor generally loses to the competing Ryzen 7 5800X in other applications as well (though fortunately it bests its predecessor). The exceptions here are mainly tasks requiring a large number of purely mathematical calculations, as well as Blender or POV-Ray.

To make matters worse, Intel's new computing unit consumes more power than the Core i7-10700K CPU, not to mention the Ryzen.

Intel Core i7-11700K CPU will debut on March 30, this year, which means that the review was published more than three weeks before the release - this happened because some stores started selling the model in question earlier and AnandTech's editors managed to get their hands on one of the copies (thus bypassing the NDA agreement imposed by Intel).
