Raptor and Alder Lake Flavors of Intel’s Core i5-13400F Perform About the Same
With the introduction of the non-K 13th Generation Raptor Lake CPU lineup, Intel has started using a mix of Raptor Lake and Alder Lake dies on their latest generation Intel Core CPUs. But how much faster the Raptor Lake version is than the Alder Lake version has remained a mystery until now.
HWCooling.net got the Alder and Raptor Lake versions of the i5-13400F CPU and benchmarked them. The performance gap seems to be almost non-existent, with at best a 5% difference in performance between the two versions in real-world, synthetic, and game benchmarks.
It has long been known that Intel will be reusing the Alder Lake CPU architecture in some of its latest 13th Gen non-K Raptor Lake processors to improve yields and reduce waste. For the i5-13400F, Intel achieved this strategy by repurposing the i9-12900/12900K die for the i5-13400 CPU by disabling some of the P-cores and CPU caches.
According to HWCooling, the Raptor Lake version steps B0 while the Alder Lake version steps C0. However, the stepping numbers are not printed on the physical chips so if you want to identify these chips you have to check the S-Spec code which is the SRMBG of the Raptor Lake i5-13400F and his SRMBN of Alder Lake’s counterpart I have. .
Unfortunately, finding the Raptor Lake version at retail is nearly impossible. According to HWCooling, virtually all retail i5-13400Fs are Alder Lake versions, while Raptor Lake models can be seen in his OEM market.
Performance, clock speed and power consumption tests
Both i5-13400F flavors were tested in several CPU benchmarks including Cinebench R23, FLAC, and F1 2020. The chips were evenly matched in almost all benchmark tests, with a maximum performance delta of 5%. For example, in Cinebench R23, the Raptor Lake i5-13400F scored 16,131 points in the multicore test, while the Alder Lake version scored 16,038 points. This is his 0.6% difference in score.
In F1 2020, we saw a little more difference with the Raptor Lake chip leading Alder Lake’s counterpart by 5%, with an average frame rate of 325.8 frames per second (fps) versus Alder Lake’s 311.4fps. However, the Raptor Lake version outperformed the Alder Lake version by 10%, more importantly the minimum of 258.5fps vs. 234.7fps.
However, not all games are susceptible to the Raptor Lake architecture. Shadow of the Tomb Raider was also tested and showed identical frame rate values between the two chips.
Both chips showed similar memory and cache performance. AIDA64 showed nearly identical read, write, and latency performance between the two versions. The only exception was the L2 cache performance, where the Raptor Lake chip was 33.3% faster than the Alder Lake version, but HWCooling says this is an issue reported by AIDA64, so these results may not be accurate. there is.
The most interesting result was the power consumption numbers. The Raptor Lake i5-13400F was less efficient than the Alder Lake version in most tests, with the exception of the FLAC results.In the Cinebench R23, the Raptor Lake portion consumed 14% more power, compared to Alder Lake’s 95W. averaged 115W. However, the difference in efficiency in-game was less severe. On the F1 202, the Raptor Lake version averaged 55W versus Alder Lake’s 52W. This means that the efficiency has dropped by 5.7%. Power efficiency results were similar for other games.
Interestingly, FLAC audio recording results did not show the same power consumption behavior. In this test, the Raptor Lake version was 42% more efficient than his Alder Lake version, with him pulling out 18.5W versus Alder Lake’s 26.17W.
The clock speed between the two parts was the same. The average core clock of the P cores is maxed out at 4.1 GHz and 3.3 GHz on the E cores during all core workloads. P-cores average 4.58 GHz and E-cores 3.3 GHz during single-core workloads. Intel had to keep the clock speeds the same here. Otherwise, I would have been forced to part with the Raptor Lake i5-13400F under a different model name.
Thankfully, there are very few differences between the Raptor Lake and Alder Lake versions of the i5-13400F. Both models show similar performance numbers even though one version runs on the newer architecture. This boils down to the fact that both CPU versions are artificially limited to the same clock speed, and the higher clock speed potential of Raptor Lake is not used (you can avoid this limit by overclocking is no longer possible).
If you’re looking to buy the Intel i5-13400F, you can rest assured that going with the Alder Lake version won’t sacrifice any noticeable performance.
