Benchmarks of Intel’s upcoming Rocket Lake and Comet Lake Refresh CPUs have leaked and what’s interesting is that the new 11th generation line shows worse IPC than AMD’s Ryzen 5000 line with Zen 3 core architecture.
Intel’s 11th Generation Rocket Lake CPUs have a worse IPC than AMD Ryzen 5000 Zen 3, Comet Lake Refresh Core i3 CPUs compared
The benchmarks were posted at the Chinese Tech outlet, Zhuanlan, which also covered the CPU benchmarks for the Intel Core i5-11600KF and Core i5-11400F a while ago. The latest CPU benchmarks focus mainly on Intel’s Comet Lake Refresh line, which includes Core i3-10325 and Core i3-10105. These CPUs replace the Core i3-10320 and Core i3-10100, offering higher clocks, but with lower temperatures and lower power consumption. So, let’s talk about the specifications of these 2 parts before going into the IPC comparison.
The Intel Core i3-10325 is the fastest quad-core in the Comet Lake Refresh line. It has 4 cores, 8 threads, a base clock of 3.90 GHz and pulses of 4.7 GHz (1 core) and 4.5 GHz (in all cores). The CPU carries 8 MB of L3 cache, a 65W TDP and Intel UHD 630 graphics. The Intel Core i3-10105 features exactly the same core configuration, but reduces clocks and cache. The CPU works with a base of 3.7 GHz, increase of 4.4 GHz (1 core) and increase of 4.2 GHz of all cores with 6 MB of L3 cache. In terms of price, the Core i3-10325 will be sold at $ 154, while the Core i3-10105 will be sold at $ 122.
Both CPUs are only 100 MHz faster in terms of base and boost frequencies. As such, the overall performance increase is minimal by about 1-2% over existing Comet Lake Core i3 CPUs. However, the main area of improvement is energy consumption and temperatures. Intel appears to have used high quality IHS and packaging materials for its Comet Lake upgrade line, which results in a drop in temperatures of up to 5 degrees from current parts of Comet Lake.

Intel Comet Lake Update CPU power / temperature:
As for power, we are also predicting a marginal drop with Core i3-10325 running at about 9W below its predecessor, maintaining higher clock speeds and Core i3-10105 running at about 6W below its predecessor, offering 100 MHz to more watches.
But with the Comet Lake Refresh benchmarks done, we can now focus on the IPC tests between Intel Rocket Lake, Intel Comet Lake Refresh and AMD Ryzen 5000 Zen 3 Desktop CPUs. All CPUs were tested with only 4 cores and 8 enabled threads and with a fixed clock speed of 4 GHz. It can be seen that Comet Lake Refresh offers a slight increase in IPC, while Rocket Lake offers about 18% of the IPC on Comet Lake CPUs.
CPU IPC testing of Intel Rocket Lake vs Intel Comet Lake vs AMD Ryzen 5000 Zen 3 Desktop:
When it comes to comparing the AMD Ryzen 5000 Zen 3 and the 11th Generation Intel Rocket Lake CPUs, AMD’s line ends up offering an IPC 7.5% higher than the new Cypress Cove cores. This shows that AMD will maintain a good lead against Intel’s next line and Intel will once again have to rely on higher clocks to compensate for the lower IPC compared to the Zen 3 offerings. Intel will also use higher power in its top-tier parts and even more aggressive clock-boosting technologies to improve the game, but that would definitely result in very high power consumption and temperatures, as Intel itself is setting the best limit at 100C.
