With the advent of the non-Okay thirteenth Gen Raptor Lake CPU lineup, Intel began to mix ‘n match Raptor Lake and Alder Lake dies into its newest technology of Intel Core CPUs. Then again, how a lot quicker Raptor Lake variations could be over Alder Lake opposite numbers remained a thriller till now.
HWCooling.internet has obtained Alder and Raptor Lake variations of the i5-13400F CPUs and benchmarked them. Apparently the efficiency hole is nearly non-existent, with a 5% efficiency distinction at perfect between the 2 variations in real-world, artificial, and gaming benchmarks.
We’ve got identified for some time that Intel would reuse its Alder Lake CPU structure with a few of its newest thirteenth Gen non-Okay Raptor Lake processors to reinforce yields and scale back waste. On the subject of the i5-13400F, Intel achieved this technique by way of re-purposing i9-12900/12900K dies into i5-13400 CPUs by way of disabling probably the most P-cores and the CPU cache.
In step with HWCooling, the Raptor Lake edition is going by way of stepping B0, whilst the Alder Lake one is stepping C0. Then again, the stepping quantity isn’t imprinted on the bodily chip, so if you wish to establish those chips, you may have to try the S-Spec code, which is SRMBG at the Raptor Lake i5-13400F and SRMBN at the Alder Lake counterpart.
Sadly, the Raptor Lake edition is nearly not possible to seek out in retail circles. HWCooling says that almost all retail i5-13400Fs are the Alder Lake edition, whilst the Raptor Lake fashions are discovered within the OEM marketplace.
Efficiency, Clock Pace, and Energy Intake Assessments
Each flavors of the i5-13400F have been examined in different CPU benchmarks, together with Cinebench R23, FLAC, and F1 2020. The chips have been neck and neck with every different in just about all benchmark checks, with a most efficiency delta of five%. In Cinebench R23, as an example, the Raptor Lake i5-13400F scored 16,131 issues within the multi-core take a look at, whilst the Alder Lake edition scored 16,038 issues — a nil.6% distinction in ranking.
F1 2020 noticed a little extra variance, with the Raptor Lake chip main its Alder Lake counterpart by way of 5%, with a median body price of 325.8 frames in keeping with 2nd (fps) to the Alder Lake’s 311.4fps. Minimums have been extra important, despite the fact that, with the Raptor Lake edition edging out the Alder Lake edition by way of 10%: 258.5fps vs. 234.7fps.
Then again, now not all video games have been this delicate to the Raptor Lake structure. Shadow of the Tomb Raider used to be additionally examined and confirmed an identical body price numbers between the 2 chips.
Each chips demonstrated an identical reminiscence and cache efficiency. AIDA64 confirmed just about an identical learn, write, and latency efficiency between the 2 variations. The one exception used to be the L2 cache efficiency, the place the Raptor Lake chip used to be 33.3% faster than the Alder Lake edition — however HWCooling mentioned this used to be a reporting factor by way of AIDA64, so those effects might not be correct.
Probably the most attention-grabbing effects have been the facility intake numbers. The Raptor Lake i5-13400F used to be much less environment friendly than the Alder Lake edition in maximum checks, aside from for the FLAC effects. In Cinebench R23, the Raptor Lake section ate up 14% extra energy, averaging 115W to the Alder Lake’s 95W. Then again, the potency variations have been a lot much less serious whilst gaming: in F1 202, the Raptor Lake edition averaged 55W to the Alder Lake’s 52W, because of this it used to be handiest 5.7% much less environment friendly. Energy potency effects have been an identical throughout different video games.
Apparently, the FLAC audio recording effects didn’t show off the similar energy intake habits. On this take a look at, the Raptor Lake edition used to be 42% extra environment friendly than the Alder Lake edition, pulling 18.5W vs. the Alder Lake’s 26.17W.
Clock speeds between the 2 portions have been an identical. Moderate core clocks at the P-cores max out at 4.1GHz and three.3GHz at the E-cores all through an all-core workload. All over single-core workloads, the P-cores moderate 4.58GHz and three.3Ghz at the E-Cores. Intel needed to stay clock speeds equivalent right here, or it could be compelled to section out the Raptor Lake i5-13400F with a unique style identify.
Fortunately, there are slightly any variations between Raptor Lake and Alder Lake variations of the i5-13400F. Each fashions show off just about an identical efficiency figures although one edition operates on a more recent structure. This boils all the way down to the truth each CPU variations are artificially restricted to the similar clock speeds, combating Raptor Lake’s upper clock velocity doable from getting used (and you’ll be able to now not bypass this restrict with overclocking).
If you are available on the market for an Intel i5-13400F, you’ll be able to relaxation confident understanding you will not be sacrificing any noticeable efficiency by way of going with the Alder Lake edition.
