It’s lastly occurring! After two generations of getting roundly obliterated by Intel in general CPU efficiency, it seems like AMD is lastly engaged on a solution to Intel’s unimaginable massive.LITTLE processor core structure – and that would imply an finish to Intel’s long-running market dominance within the CPU house.

For these not within the know, the massive.LITTLE structure (first launched in Intel’s 12th-gen desktop processors, which we raved about in our evaluations) primarily employs two various kinds of CPU cores to enhance general efficiency: ‘efficiency’ cores that carry the processor’s main workloads, and ‘effectivity’ cores that quietly maintain background duties to release system sources.

This structure proved itself worthy instantly, and has stored Intel sitting on the prime of our greatest processors record for some time now – the present king of the CPU hill is the Intel Core i9-13900Okay, which additionally makes use of massive.LITTLE. Whereas AMD arguably has the gaming edge due to its fancy 3D V-cache tech (seen most lately within the Ryzen 9 7950X3D), Group Crimson continues to be lagging with its commonplace cores.

That would all be about to vary, although. As Tom’s {Hardware} (opens in new tab) studies, a contemporary leak has revealed an as-of-yet unnamed AMD engineering pattern, which CPU skilled @InstLatX64 (opens in new tab) believes is a trial run of a hybrid-core processor. If true, this may very well be an enormous leap ahead for AMD; whereas we don’t know when it might arrive, equipping the very best Ryzen processors with a giant.LITTLE equal would create a really tangible menace to Intel’s throne.

Evaluation: That is massive information, however let’s not get carried away

Digging into the small print of the leak slightly, we will see that the CPU in query – which is called ‘100-000000931-21_N [Family 25 Model 120 Stepping 0]’ has twelve threads unfold throughout six cores. @InstLatX64 claims these are two high-power Zen four cores and 4 energy-efficient Zen 4c cores, which means this may very well be the rumored hybrid ‘Phoenix 2’ CPU that allegedly surfaced final yr, as reported by German tech information web site 3DCenter (opens in new tab).

The Phoenix 2 chip, which apparently isn’t associated to AMD’s current Phoenix APU, is claimed to make use of the identical 12-thread configuration as this newly-leaked engineering pattern together with RDNA three built-in graphics. As Tom’s {Hardware} famous, there was some dispute over the precise particulars, and AMD has not been forthcoming with data – indicating that its personal hybrid core structure will not be but able to be unveiled.

Nevertheless, the circumstances of this leak recommend that Phoenix 2 could also be nearing a giant reveal: it got here from the MilkyWay@Dwelling database (opens in new tab), a distributing-computing undertaking (just like the well-known Folding@Dwelling (opens in new tab)) which leverages unused system sources on members’ computer systems to hold out large computational duties – on this case, creating an extremely detailed 3D mannequin of the Milky Approach. A thriller CPU was first hooked as much as MilkyWay@Dwelling in early March 2023, which means that it’s already useful and the pattern would possibly really be being examined by somebody exterior AMD, so this may very well be a quiet however intentional leak.

In any case, AMD has but to remark correctly by itself hybrid structure, so we will solely speculate wildly as to when Phoenix 2 would possibly really arrive. However contemplating that AMD’s Ryzen CPUs already put up a good combat towards Intel’s Core line with out hybrid cores, I believe Intel wants to begin worrying. As a PC gamer, AMD has lengthy been my chipmaker of selection, and this might show to be the loss of life knell for Intel within the gaming house – except, in fact, Group Blue bites again by revealing its personal counter to AMD’s 3D V-cache!
