Intel afresh accepted that its 11th gen Rocket Lake-S desktop CPU calendar is ablution on the 30th of March, 2021. In acknowledgment to Hardwareluxx, an Intel abettor accepted the Rocket Basin CPU’s barrage schedule.  

“The sales embargo for 11th Gen Desktop processors (Rocket Basin S) is March 30, 2021 at 6 a.m. PT / 9 a.m. ET”. – Official Intel Spokesman to HardwareLuxx.

It now appears that motherboard bell-ringer MSI has clearly apart abounding PCIe Gen 4.0 interface abutment for Intel’s accessible Rocket Basin CPUs on its absolute Z490 motherboard lineup. All MSI Z490 motherboards will be acknowledging PCIe 4.0 with the accessible Intel 11th gen Intel processors.

Through an amend to the latest BIOS, MSI Z490 motherboards will action abundant bandwidth and achievement for PCIe 4.0 M.2 SSDs and cartoon cards.

According to MSI, the aggregation says it has advised its Z490 boards accurately to abutment Gen 4.0 from the get-go by implementing “PCIe 4.0 accessible alarm generator, lane switch, redriver, PCIe slots, and M.2 connectors.”

You charge amend your accordant Z490 motherboard with the latest BIOS optimized for PCIe 4.0, in adjustment to adore the apart achievement of PCIe 4.0 interface.

Here is the account of accordant motherboards:

Intel’s 11th gen desktop processor calendar will affection both Rocket Lake-S and Comet Lake-S “refresh” CPUs. The 11th bearing calendar includes 13 Rocket Lake/RKL and a absolute of 13 Comet Basin brace desktop CPUs. Rocket Basin calendar appearance the amount i9, i7 & i5 variants, while the Comet Basin brace desktop CPUs will appear in Amount i3, Pentium & Celeron variants.

Rocket Lake-S desktop belvedere should additionally be the aftermost CPU architectonics to be based on an avant-garde 14nm action node. Comet Lake-S was additionally fabbed on this crumbling action node, which has captivated Intel aback in agreement of IPC boost and ability assets over AMD’s Ryzen lineup.

RKL processor ancestors is accepted to allotment the aforementioned atrium and motherboard affinity as the accepted 10th Gen Comet Basin processors, appropriately accouterment an advancement aisle alike for those agitation the flagship Amount i9-10900K Comet basin CPU.

Rocket Lake-S will be housed on the new 500-series motherboards. Although the Rocket Lake-S calendar will be the aftermost to affection the LGA1200 socket, Intel is planning a abounding ambit of chipsets, including workstation W580, high-end gaming Z590, H570, and budget-oriented B560 and H510 series.

The accepted 400-series motherboard chipsets will additionally abutment these accessible SKUs afterwards a BIOS update; however, there is a catch. Rocket Basin CPUs “may or may not” assignment on some of the 400-series motherboard chipsets.

I accept explained this afore as well, but to reiterate the capital credibility already again, one columnist of a Chinese appointment and tech website afresh acquaint some absorbing allegation on Intel’s accessible 11th bearing Rocket Lake-S CPU lineup.

The columnist has explained in abyss as to why Rocket Basin processors won’t be accordant with some of the 400-series motherboard chipsets. Though, you should accumulate in apperception that this may or may not administer to all motherboard vendors/AIBs and their corresponding 400-series boards, but the abstruse account accustomed by the columnist warrants some attention, and ability about-face out true.

In case you didn’t know, Intel afresh appear that the aggregation has alone official abutment for the Rocket Lake-S CPU calendar on B460 and H410 motherboard series. Intel has accurately declared that “motherboards based on Intel B460 or H410 chipsets are not accordant with accessible 11th gen Intel amount processors.”

The B460 is a mid-tier chipset, and the H410 desktop motherboard chipset is an entry-level offering.

The new address from the said Chinese tech commodity claims that the accessible 14nm Rocket Basin chips ability not alike assignment on best of the Z490 motherboards as well, citation affidavit like abridgement of chipset and BIOS akin support, and how the motherboard’s ability commitment subsystem has been designed.

First of all you charge apperceive that the desktop 400-series ancestors consists of six chipsets: Z490, W480, Q470, H470, B460 and H410. Intel has categorized and anecdotal these chipsets beneath altered groups, like “Comet Basin PCH-H” and “Comet Basin PCH-V”.

The Z490, W480, Q470 and H470 chipsets all abatement beneath the Comet Basin PCH-H category, while the B460 and H410 chipsets accord to the Comet Basin PCH-V group. So based on this analysis we can assumption why the B460 and H410 motherboard alternation accept been afar from the Rocket Basin CPU abutment list, back they abatement beneath the lower bank in the hierarchy.

To explain things in added details, the columnist of that tech commodity explains that anniversary CPU has a different “CPU_ID” that the motherboard chipset utilizes to analyze the processor chip. From a analytic point of view, the processor will not assignment if the chipset cannot appropriately admit the CPU_ID.

When this happens, there will be a self-test absurdity situation; and the computer will artlessly not be able to alpha commonly during the BIOS POST. However, there is a workaround to bypass this, and it artlessly consists of disabling the CPU_ID in the Intel Management Engine (ME) allotment of the BIOS.

Following this action will eventually about-face off chipset analysis of the ‘CPU_ID’ in question.

As I accept explained in my previous article, some motherboard vendors are now absolution revised H410 and B460 motherboards with the H470 chipset to board abutment for Rocket Lake, back Intel fabricated the official advertisement that the aggregation is bottomward support.

Ironically, Gigabyte has already listed and aircraft its H410M DS2V V2 and H410M S2H V2 boards that advantage the H470 chipset, best acceptable afterwards application this aforementioned workaround.

Secondly, the abridgement of BIOS abutment is addition reason. As we already apperceive BIOS plays a actual huge role actuality as well, back it comes to any processor support. Now, if accept the CPU’s microcode is not begin in the database, afresh the processor/chip is acutely not activity to assignment on that accurate motherboard chipset.

Inside Intel’s BIOS, there’s a affair alleged CMC (CPU Microcode), which anon determines what CPU your motherboard can use. Back Intel developed the Comet Basin PCH-V alternation of motherboards, the aggregation ability accept alone abutment for the 11th gen Rocket Basin processors while authoritative the BIOS for these chipsets, B460 and H410.

It ability be accessible that the processors weren’t accustomed any priority, or taken into application during the development of the BIOS, by bottomward the microcode for these chipsets.

However, as the columnist explains already afresh there is a workaround for this.

By extracting the microcode from accept the Z590 chipset’s BIOS and afresh copying/implanting it into the ambition motherboard which requires the microcode, ability advice affected this issue. This action is not new though, back several motherboard vendors accept done this in the accomplished as well.

The third capital and an important acumen accustomed by the columnist is the ability accumulation commitment arrangement of the said motherboard. The ability commitment subsystem helps in converting the 12V and 5V voltages bottomward to lower voltages that the processor can afresh use afterwards.

The ability accumulation on Intel’s motherboard is disconnected into the afterward voltages, such as the Vcore (core), Vgt (core display), VCCSA (system agent), VCCIO (input and output), VCCM (memory), VCCST (maintenance voltage), VCCST_PLL (clock aliment voltage), and few others.

Usually we will analyze alone the Vcore and Vgt ability levels to adjudicator the akin of any motherboard.

According to the author’s findings, the Intel 10th and 11th bearing Comet Lake-S and Rocket Lake-S processors accept not afflicted on the Vcore and Vgt voltage values. However, the VCCSA and VCCIO voltages accept afflicted slightly.

Further all-embracing account of this accomplished ability commitment arrangement is “highly” abstruse in nature, so I’m not activity into all the details, except for the capital points. So unless you are from an electronics background, or accept acquaintance with motherboard chipset ambit diagrams, voltages and the like, it would be adamantine to grasp.

But nonetheless, from the author’s allegation it appears that with Rocket Lake-S lineup, Intel has best acceptable afflicted the ability commitment approach of the VCCSA to SVID, which agency that the voltage supplied by this appearance is controlled anon by the CPU, aloof like Vcore, so that there is no accepted ability accumulation or any added PWM.

So a PWM that supports the IMVP8 blueprint is appropriate here.

Moreover, some motherboards that abridgement a SVID PWM ambassador cannot board these new Rocket Lake-S chips. It is additionally not accessible to allotment the ability commitment or use addition PWM. As the tech columnist mentioned, we charge a PWM IC actuality which absolutely complies with Intel’s IMVP8 specifications.

When it comes to VCCIO, he has provided two ambit diagrams of the B460 and Z590 motherboards. From his ascertainment the columnist addendum that VCCIO for Rocket Lake-S is disconnected into three parts: VCCIO_0, VCCIO_1_2.

The B460 motherboard is not affiliated to the VCCIO_1_2 part, as apparent in the diagram below. This absolutely agency that RSVD pins on the B460 and H410 motherboards are empty. Due to this there is no ability activity to VCCIO_1_2, which feeds the PCIe interface.

The CPU has no ability ascribe in this section, and back VCCIO_1_2 governs abstracts buses such as PCIe, so the CPU cannot barter abstracts with the ambience and the computer will not assignment naturally. That sums it all.

It charcoal to be apparent how Intel’s Rocket Basin CPU calendar will assemblage up adjoin AMD’s Ryzen 5000 series.
