World’s Fastest Discrete Graphics Memory From Micron Powers NVIDIA’s Breakthrough Gaming Speeds

Micron GDDR6X accelerates photorealistic 3D experiences at 1 terabyte per second, rates once thought impossible

BOISE, Ida¬≠ho, Sept. 01, 2020 (GLOBE NEWSWIRE) ‚ÄĒ Micron Tech¬≠no¬≠lo¬≠gy, Inc. (Nasdaq: MU), today announ¬≠ced the world‚Äôs fas¬≠test dis¬≠crete gra¬≠phics memo¬≠ry solu¬≠ti¬≠on, GDDR6X, the first to power sys¬≠tem band¬≠width up to 1 tera¬≠byte per second (TB/s). Working with visu¬≠al com¬≠pu¬≠ting tech¬≠no¬≠lo¬≠gy lea¬≠der NVIDIA, Micron debut¬≠ed GDDR6X in the new NVIDIA¬ģ GeForce RTX‚ĄĘ 3090 and GeForce RTX 3080 gra¬≠phics pro¬≠ces¬≠sing units (GPUs), which are tail¬≠o¬≠red to sup¬≠port the fast speeds that immersi¬≠ve, high-per¬≠for¬≠mance gam¬≠ing appli¬≠ca¬≠ti¬≠ons demand.

‚ÄúOur mul¬≠ti¬≠le¬≠vel signal¬≠ing inno¬≠va¬≠ti¬≠on in GDDR6X has shat¬≠te¬≠red con¬≠ven¬≠tio¬≠nal band¬≠width limits, clo¬≠cking record-brea¬≠king speeds,‚ÄĚ said Tom Eby, seni¬≠or vice pre¬≠si¬≠dent and gene¬≠ral mana¬≠ger of the Com¬≠pu¬≠te & Net¬≠wor¬≠king Busi¬≠ness Unit at Micron. ‚ÄúUnli¬≠ke tra¬≠di¬≠tio¬≠nal memo¬≠ry, GDDR6X has unpar¬≠al¬≠le¬≠led data rates that can keep pace with gam¬≠ing inno¬≠va¬≠ti¬≠on and data-hun¬≠gry appli¬≠ca¬≠ti¬≠ons ‚ÄĒ set¬≠ting a new stan¬≠dard for gra¬≠phics memory.‚ÄĚ

Micron‚Äôs GDDR6X ser¬≠ves as a powerful enabler of NVIDIA GeForce RTX 3090 and GeForce RTX 3080 gra¬≠phics cards‚Äô per¬≠for¬≠mance. Buil¬≠ding on its most recent col¬≠la¬≠bo¬≠ra¬≠ti¬≠on with NVIDIA for the GeForce RTX gra¬≠phics card (enab¬≠led by GDDR6), Micron trans¬≠forms the memory/GPU inter¬≠face with GDDR6X, acce¬≠le¬≠ra¬≠ting per¬≠for¬≠mance on com¬≠plex gra¬≠phics workloads across next-gene¬≠ra¬≠ti¬≠on gam¬≠ing applications.

‚ÄúWith the unpre¬≠ce¬≠den¬≠ted speed of GDDR6X, Micron has deli¬≠ver¬≠ed tomorrow‚Äôs memo¬≠ry tech¬≠no¬≠lo¬≠gy today, and it‚Äôs at the heart of NVIDIA GeForce RTX 3090 and 3080 GPUs ‚ÄĒ hel¬≠ping us deli¬≠ver rich, rea¬≠li¬≠stic, cine¬≠ma¬≠tic user expe¬≠ri¬≠en¬≠ces,‚ÄĚ said Jeff Fisher, seni¬≠or vice pre¬≠si¬≠dent of the GPU Busi¬≠ness Unit at NVIDIA. ‚ÄúBuil¬≠ding on a histo¬≠ry of col¬≠la¬≠bo¬≠ra¬≠ti¬≠on that star¬≠ted with GDDR5, we‚Äôre thril¬≠led to have reinven¬≠ted the memory/GPU inter¬≠face with Micron, set¬≠ting a new bar for high-per¬≠for¬≠mance, high-reso¬≠lu¬≠ti¬≠on gaming.‚ÄĚ

As PC gam¬≠ing evol¬≠ves in sophisti¬≠ca¬≠ti¬≠on, gamers today demand the hig¬≠hest per¬≠for¬≠mance for their advan¬≠ced gra¬≠phics cards ‚ÄĒ a requi¬≠si¬≠te for smooth ani¬≠ma¬≠ti¬≠on, sharp visu¬≠als, 8K reso¬≠lu¬≠ti¬≠on and real-time ray tra¬≠cing, a ren¬≠de¬≠ring tech¬≠ni¬≠que that results in rea¬≠li¬≠stic light reflec¬≠tions and cine¬≠ma¬≠tic effects. GDDR6X‚Äôs ground¬≠brea¬≠king speed offers dis¬≠cer¬≠ning gamers high-reso¬≠lu¬≠ti¬≠on expe¬≠ri¬≠en¬≠ces with maxi¬≠mum frame rates and instant ren¬≠de¬≠ring, allo¬≠wing users to expe¬≠ri¬≠ence high¬≠ly rea¬≠li¬≠stic and reac¬≠ti¬≠ve effects wit¬≠hout jar¬≠ring lags. Com¬≠bi¬≠ned with NVIDIA‚Äôs GeForce RTX 3090 and GeForce RTX 3080 GPUs, GDDR6X‚Äôs ultra-band¬≠width capa¬≠bi¬≠li¬≠ties impro¬≠ve real-time ray tra¬≠cing and neu¬≠ral gra¬≠phics pro¬≠ces¬≠sing to crea¬≠te pho¬≠to¬≠rea¬≠li¬≠stic and immersi¬≠ve vir¬≠tu¬≠al worlds in PC games.

The new NVIDIA GeForce RTX 30 Series GPUs ‚ÄĒ the second gene¬≠ra¬≠ti¬≠on of the NVIDIA RTX PC gam¬≠ing plat¬≠form ‚ÄĒ fea¬≠ture new ray tra¬≠cing cores, Ten¬≠sor Cores and strea¬≠ming mul¬≠tipro¬≠ces¬≠sors. The results are stun¬≠ning visu¬≠als, ama¬≠zin¬≠gly fast frame rates and arti¬≠fi¬≠ci¬≠al intel¬≠li¬≠gence acce¬≠le¬≠ra¬≠ti¬≠on for games and crea¬≠ti¬≠ve appli¬≠ca¬≠ti¬≠ons. Powered by the NVIDIA Ampere archi¬≠tec¬≠tu¬≠re, which deli¬≠vers increa¬≠ses of up to 1.9 times per¬≠for¬≠mance-per-watt over the pre¬≠vious gene¬≠ra¬≠ti¬≠on, the RTX 30 Series effort¬≠less¬≠ly powers gra¬≠phics expe¬≠ri¬≠en¬≠ces at all reso¬≠lu¬≠ti¬≠ons, even up to 8K. The series repres¬≠ents the grea¬≠test GPU gene¬≠ra¬≠tio¬≠nal leap in NVIDIA‚Äôs history.

Bey­ond the Bina­ry: First to Imple­ment PAM4 in Memo­ry, Micron Sets New Benchmark

Micron achie¬≠ved GDDR6X‚Äôs breakth¬≠rough band¬≠width by app¬≠ly¬≠ing inno¬≠va¬≠ti¬≠ve signal trans¬≠mis¬≠si¬≠on tech¬≠no¬≠lo¬≠gy, four-level pul¬≠se ampli¬≠tu¬≠de modu¬≠la¬≠ti¬≠on (PAM4), to revo¬≠lu¬≠tio¬≠ni¬≠ze how memo¬≠ry moves data. Sin¬≠ce 2006, Micron‚Äôs engi¬≠neers and rese¬≠ar¬≠chers have explo¬≠red app¬≠ly¬≠ing mul¬≠ti¬≠le¬≠vel signal¬≠ing to the memo¬≠ry inter¬≠face. Over 45 patents later, Micron is the first in the indus¬≠try to imple¬≠ment PAM4 in memo¬≠ry, crea¬≠ting a new bench¬≠mark for future gene¬≠ra¬≠ti¬≠ons of gra¬≠phics memory.

By using PAM4 mul¬≠ti¬≠le¬≠vel signal¬≠ing tech¬≠ni¬≠ques, GDDR6X trans¬≠fers data much fas¬≠ter, doubling the input/output (I/O) data rate. Until now, gra¬≠phics memo¬≠ry was cap¬≠ped at 64 giga¬≠bytes per second (GB/s), trans¬≠mit¬≠ting one bit per cycle through the tra¬≠di¬≠tio¬≠nal bina¬≠ry stan¬≠dard, which reli¬≠es on two signal levels to trans¬≠mit data encoded as 1s or 0s. Ins¬≠tead, Micron‚Äôs novel PAM4 tech¬≠ni¬≠que employs four distinct levels to trans¬≠mit two bits of data to and from the memo¬≠ry at a time. As a result, Micron‚Äôs GDDR6X dra¬≠ma¬≠ti¬≠cal¬≠ly increa¬≠ses memo¬≠ry band¬≠width to 84 GB/s for each com¬≠po¬≠nent, trans¬≠la¬≠ting to sys¬≠tem band¬≠width of up to 1 TB/s ‚ÄĒ rates once thought impossible.

Micron’s GDDR6X is also the only memo­ry device using PAM4 that can be desi­gned and built in mass pro­duc­tion volu­mes, brin­ging cut­ting-edge I/O rese­arch to mar­ket. With its board design and pack­a­ging careful­ly fine-tun­ed for sim­pli­ci­ty by Micron’s gra­phics memo­ry experts, GDDR6X offers cus­to­mers easy imple­men­ta­ti­on and less manu­fac­tu­ring com­ple­xi­ty than other high-band­width solu­ti­ons on the mar­ket. Nota­b­ly, GDDR6X dou­bles the data rate in a chan­nel wit­hout doubling the requi­red ope­ra­ting fre­quen­cy, crea­ting a smooth, real-time expe­ri­ence for gamers.

In addi­ti­on, GDDR6X deli­vers lower power per tran­sac­tion (pJ/bit) than pre­vious gene­ra­ti­ons, making it ide­al for ener­gy-sap­ping workloads like gam­ing and other high-band­width gra­phics appli­ca­ti­ons, which demand both light­ning fast and low-power memo­ry. GDDR6X also fea­tures the abili­ty to sca­le power down or up, allo­wing users to dial back per­for­mance to save energy.


The GeForce RTX 3080 is available for purcha¬≠se start¬≠ing Sept. 17, and the GeForce RTX 3090 is available start¬≠ing Sept. 24 on NVIDIA‚Äôs web¬≠site. Both will be available as cus¬≠tom boards, inclu¬≠ding stock-clo¬≠cked and fac¬≠to¬≠ry-over¬≠clo¬≠cked models from top add-in card pro¬≠vi¬≠ders and in gam¬≠ing sys¬≠tems from lea¬≠ding OEMs and sys¬≠tem builders.

GDDR6X is now available as part of Micron‚Äôs new Ultra-Band¬≠width Solu¬≠ti¬≠ons port¬≠fo¬≠lio. Micron deli¬≠vers GDDR6X memo¬≠ry in 8 giga¬≠bits (Gb) den¬≠si¬≠ty, with speeds of 19 to 21 Gb/s. Start¬≠ing in 2021, 16Gb den¬≠si¬≠ty units will be added. Part¬≠ners and cus¬≠to¬≠mers inte¬≠res¬≠ted in explo¬≠ring GDDR6X for their high-per¬≠for¬≠mance solu¬≠ti¬≠ons ‚ÄĒ whe¬≠ther for gam¬≠ing, arti¬≠fi¬≠ci¬≠al intel¬≠li¬≠gence infe¬≠rence or pro¬≠fes¬≠sio¬≠nal visua¬≠liza¬≠ti¬≠on ‚ÄĒ can find out more here.
