Intel 11th Gen Core i5 CPUs reviewed early with benchmarks

We’ve been seeing benchmark leaks for Intel’s upcoming Rocket Lake-S series of processors for a while now, although most of these leaks have focused on 8-core SKUs. That changed this week with the first benchmark leaks for two of Intel’s 6-core 11th Gen Core processors, giving us a look at what’s to come for the mainstream segment. 

A Chinese website has obtained and reviewed both the Intel Core i5-11600KF and i5-11400F, benchmarking the two processors across a range of synthetic tests, including Cinebench R15, R20, and R23, CPU-Z 17 and 19, 3DMark Time Spy and Fire Strike, and AIDA 64.

The Intel Core i5-11400F is a 6C/12T processor with a 65W TDP and a 2.6GHz base clock that boosts up to 4.4GHz. The Core i5-11600KF is also a 6C/12T processor, but features a 125W TDP and a 3.9GHz base clock, boosting up to 4.9GHz. Both processors offer PCIe 4.0 support and do not feature an iGPU.

The system used for the benchmarks included a Z490 Gigabyte Aorus Ultra motherboard with the latest BIOS and 16GB of Zadak Spark RGB DDR4-3600 memory. The processors were cooled using a triple-fan PCCooler GI-CX360 ARGB AIO liquid cooler. The benchmarks include results for both processors at stock speeds, and another set of results for the Core i5-11600 running at 4.8GHz.

You can see all of the benchmark results in the table below:

Benchmark Intel Core i5-11400F  Intel Core i5-11600KF Intel Core i5-11600 @ 4.8Ghz
Cinebench R15 (multi-core) 1593 1726 1793
Cinebench R15 (single-core) 219 243 241
Cinebench R20 (multi-core) 3951 4267 4454
Cinebench R20 (single-core) 539 589 579
Cinebench R23 (multi-core) 10132 11000 11559
Cinebench R23 (single-core) 1410 1545 1519
3DMark Time Spy 8316 9009 8990
3DMark Time Spy Extreme 3961 4367 4448
3DMark Fire Strike Extreme 20668 22567 23437
CPU-Z 17 (multi-core) 4304.8 4704.6 4900.4
CPU-Z 17 (single-core) 591 659.2 647.4
CPU-Z 19 (multi-core) 6337.1 6891.4 7240.4
CPU-Z 19 (single-core) 847.3 944.7 930.8
AIDA-64 FPU (Watts) 145.1 209.4 204.8
AIDA-64 FPU (Temperature) 70 85 83

Performance and overclocking could be improved further with another BIOS update. In particular, the Core i5-11600 ran too hot at 4.8GHz according to the reviewer, even with an AIO rated for up to 350W of cooling. If a BIOS update does come, then the site says it will run re-tests and add gaming benchmarks to the list.

Intel is expected to launch its 11th Gen Core “Rocket Lake-S” processors on the 30th of March.

KitGuru says: Intel’s next line of desktop processors are coming up very soon. What do you all think of these early Core i5 performance results? Are you thinking about upgrading to Intel 11th Gen in the next few months?
