Blue team’s Rocket Lake processor family is currently the target of negative reviews. Made available with chips Gear 2 An important advantage of the mode has emerged.

What are Gear 1 and 2 that come with Rocket Lake?

Introduced with Intel Rocket Lake Gear 2 with mode of the memory controller allowed it to run at half the speed of the memory. Thus, with the new platform Gear 1, which can reach higher memory frequencies, memory controller 1:1 In the case where it works at a rate, although it reaches lower frequencies more stable works.

Included in Intel’s technical specifications table DDR4-3200 MHz ve 2933 MHz’e The expression as much is the values ​​that can be reached in Gear 1 mode, where the chip works stably. Moreover Gear 1’s limits are 3733/3866 MHz determined as. If we look for a user who wants to run their DDR4 RAM at 4000 MHz with Rocket Lake

MCLK =Reference clock rate x Gear x QCLK rate / 2 (Dual Data Rate [DDR])

according to the formula

100 MHz x 1 x 40/2 (practically does not work as the QCLK range is 6-31)

100 MHz x 2 x 20 / 2

Core i5-11600KF ve Core i5-11400F test edildi

A table of 133 MHz x 2 x 15/2 emerges.

One more small detail. According to these rates DDR4-7466 and DDR4-7533 MHz Although possible, they are of course not suitable for daily use. Intel’s For DDR5 on the integrated memory controller side We can say that he has already made his preparations.

Gear 2 higher performance on Core i5-11400F

Yes, our main subject is Gear 1/2 performance difference Going back, the first chips whose review was published were also TDP budget wider solutions. Core i5-11400F’in With the publication of his reviews, a remarkable detail emerged.

65 watts TDP’li and also in Rocket Lake the best chips Core i5-11400F at the same RAM frequency when combined with DDR4-3733 MHz RAMs. Gear 2’s performance increase compared to Gear 1 observed to exhibit.

The difference at the level of 3.42% in the Cinebench R23 multi-track test To 6% in MySQL test reached. Even with a slight difference in games, Gear 2’s advantageous reported to be in position.

AMD’nin To UCLK and MCLK The performance difference between the Gear 1/2, which works similarly, is, as we mentioned at the beginning. by the processor’s thermal budget closely related.

Because the processor was able to work more comfortably thanks to the integrated memory controller, which consumes less power as a result of the halved frequency, and the processor has more budget.

More share left for the processor

Uncore in Gear 1 mode of units other than the cores of the processor It consumes between 5-10 watts more Let’s add.

In the minds of hardware lovers 8 cores with 16 threads There are already questions about how the Core i7 and Core i9 processors will react to the Gear 1/2 change.
