Intel is operating by itself type of sturdy cache that AMD pioneered with its three-D V-Cache generation, despite the fact that it’s however no less than a few generations away.
Following Intel CEO Pat Gelsinger’s Intel Innovation 2023 keynote, Gelsinger held a Q+A consultation with participants of the click the place he was once requested if Intel would undertake the equivalent stackable cache generation that AMD has been the usage of to make probably the most absolute best processors available available on the market.
“While you reference V-Cache,” Gelsinger mentioned, as reported by means of Tom’s {{{Hardware}}}, “you are speaking about an overly particular generation that TSMC does with a few of its shoppers as smartly. Clearly, we are doing that otherwise in our composition, correct? And that particular form of generation is not one thing that is a part of [the new Intel Core Ultra processors], alternatively in our roadmap, you are seeing the theory of three-D silicon the place we’re going to have cache on one die, and we’re going to have CPU compute at the stacked die on highest of it, and clearly the usage of [embedded multi-die interconnect bridges] that Foveros [chiplet packaging technology] we’re going so that you can compose other choices.”
Any person who noticed Gelsinger’s keynote would have noticed how Intel’s upcoming processor roadmap will transfer closely into the multi-chiplet module (MCM) design paradigm, the place other processor elements very similar to the iGPU, cache, and Intel’s new nueral processing unit can be discrete segments bonded in combination right kind proper right into a unmarried unit relatively than forged in combination unexpectedly.
The MCM procedure permits for lots further flexibility than the extra restrictive monolithic silicon fabrication that has historically been used previously, and would clearly open up a wide variety of recent probabilities for chip design that were not good the usage of a monolithic construction.
The obvious of those is stacked cache, which a really perfect deal will build up the to be had cache reminiscence pool for the processor that interprets into such a lot faster processing of particular CPU workloads.
AMD has already confirmed the advantages of this expanded cache pool when it presented the AMD Ryzen 7 5800X3D chip in 2022, adopted by means of AMD Ryzen 7 7800X3D, AMD Ryzen 9 7900X3D, and AMD Ryzen 9 7950X3D previous this .
“We in fact in point of fact really feel excellent that we have got refined choices for next-generation reminiscence architectures, benefits for three-D stacking, for each little die, in conjunction with for terribly massive tactics for AI and high-performance servers as smartly,” Gelsinger mentioned. “So now we have a complete breadth of the ones applied sciences. We’re going to be the usage of the ones for our merchandise, in conjunction with presenting it to the [Intel] Foundry shoppers as smartly.”
Stackable cache is highest the start for Intel’s packaging tech
Intel’s transfer into MCM processor design the usage of its embedded multi-die interconnect bridge (EMIB) and Forveros chip packaging generation is a big step ahead for the chipmaker.
The absolute best Intel processors of the previous few years have relied closely on merely throwing uncooked electric energy into its processors to extend capacity, making its high-end Intel Core i9-12900K and Intel Core i9-13900K particularly energy hungry processors.
This has allowed it to regain numerous floor misplaced to the absolute best AMD processors of the previous few years, alternatively this is not a workable longer term solution, or even Nvidia is reportedly seeing the information of moving to an MCM design for its next-gen Nvidia Blackwell development.
And whilst the theory of a long term Intel processor, in all probability once Lunar Lake, that incorporates stacked cache is thrilling, it’s going to must highest be the start of new processor traits, no longer the easiest of it.
