Within the present battle over GPU reminiscence speeds between AMD and Nvidia, Micron and Nvidia scored a decisive victory. Collectively the businesses made GDDR6X, which tops out round 21Gb/s. That reminiscence discovered its solution to Nvidia’s high-end GPUs, named the RTX 3080 and 3090. AMD, in the meantime, used slower 16Gb/s modules on its RX 6900 XT, however then bumped that as much as 18Gb/s for the upgraded RX 6950 XT. As you’ll be able to see, there’s a reasonably clear delta there, though AMD’s choices had been no slouches because of Infinity Cache. Now Samsung has one-upped Micron, and has developed the world’s first 24Gb/s GDDR6. Word it’s not making use of an X to the RAM’s branding, so it’s 5 % much less cool-sounding.
Samsung made the announcement in a press launch. It says it’s designed particularly for “next-generation, high-end graphics.” Apparently, it didn’t identify any prospects, however it appears unlikely it could have unveiled it with out having not less than one massive buyer already signed. Samsung says it was capable of hit these speeds because of the mix of a brand new circuit design and superior insulating materials. Not like its competitor, GDDR6X, GDDR6 is JEDEC-compliant. Samsung used its third era 10nm course of together with excessive ultraviolet (EUV) expertise within the manufacturing course of.
Samsung is already sampling the brand new chips in 16Gb capability to unnamed firms. It says its prospects will being validating them within the close to future. This timing is intriguing since each AMD and Nvidia will launch next-gen GPUs quickly as properly. It looks as if a no brainer that AMD would undertake it, however it’s unknown if Micron and Nvidia have one thing like GDDR7 within the works. Both means, if Samsung’s providing is quicker than no matter Nvidia is testing, it could probably swap camps to acquire it. Earlier rumors indicated Nvidia had GDDR7 at 24Gb/s for its 40-series, however that’s nonetheless only a rumor.
The superior insulating materials Samung is utilizing is a Excessive-Ok Steel Gate (HKMG), which prevents present leakage. This permits the IC to be extra environment friendly, and function at decrease temperatures. Samsung says the brand new modules assist 1.1V of energy, versus the business commonplace of 1.35/125V. It utilizing a brand new dynamic energy switching expertise to modify backwards and forwards when needed. Total, this enables for a 20 % discount in energy consumption in comparison with its earlier 18Gb/s modules. It’s additionally 30 % quicker, which permits for a most of 1.1TB/s of bandwidth.
This newest information from Samsung will definitely up the ante within the upcoming GPU wars. For this era of playing cards (RDND2 vs. Ampere) AMD lagged behind Nvidia on the spec sheet, however largely made up the distinction with its Infinity Cache. Nvidia is rumored to be taking a web page from this playbook for its 40-series Ada Lovelace structure. It’s been speculated Nvidia will crank up L2 by 16x over Ampere. For its half, AMD could be doubling down on Infinity Cache, utilizing 3D-stacking to actually double its dimension. That quantity of cache using alongside (or on high of) super-fast GDDR6 reminiscence could possibly be a potent mixture certainly. For now, we should anticipate the opposite shoe to drop. Will the primary buyer be AMD, Nvidia, or Intel?
