AMD stellt Vega-Architektur auf CES vor

SUNNYVALE, Calif. — Jan. 5, 2017 — Today AMD (NASDAQ: AMD) unvei­led preli­mi­na­ry details of its forth­co­m­ing GPU archi­tec­tu­re, Vega. Con­cei­ved and exe­cu­t­ed over 5 years, Vega archi­tec­tu­re enab­les new pos­si­bi­li­ties in PC gaming, pro­fes­sio­nal design and machi­ne intel­li­gence that tra­di­tio­nal GPU archi­tec­tures have not been able to address effec­tively. Data-inten­si­ve workloads are beco­m­ing the new nor­mal, and the par­al­lel natu­re of the GPU lends its­elf ide­al­ly to tack­ling them. Howe­ver, pro­ces­sing the­se huge new data­sets requi­res fast access to mas­si­ve amounts of memo­ry. The Vega architecture’s revo­lu­tio­na­ry memo­ry sub­sys­tem enab­les GPUs to address very lar­ge data sets spread across a mix of memo­ry types. The high-band­width cache con­trol­ler in Vega-based GPUs can access on-packa­ge cache and off-packa­ge memo­ries in a fle­xi­ble, pro­gramm­a­ble fashion using fine-grai­ned data move­ment.

It is incredi­ble to see GPUs being used to sol­ve giga­byte-sca­le data pro­blems in gaming to exa­byte-sca­le data pro­blems in machi­ne intel­li­gence. We desi­gned the Vega archi­tec­tu­re to build on this abi­li­ty, with the fle­xi­bi­li­ty to address the extra­or­di­na­ry breadth of pro­blems GPUs will be sol­ving not only today but also five years from now. Our high-band­width cache is a pivo­tal dis­rup­ti­on that has the poten­ti­al to impact the who­le GPU mar­ket,” said Raja Kodu­ri, seni­or vice pre­si­dent and chief archi­tect, Rade­on Tech­no­lo­gies Group, AMD.

High­lights of the Vega GPU architecture’s advan­ce­ments inclu­de:

  • The world’s most advan­ced GPU memo­ry archi­tec­tu­re: The Vega archi­tec­tu­re enab­les a new memo­ry hier­ar­chy for GPUs. This radi­cal new approach comes in the form of a new high-band­width cache and its con­trol­ler. The cache fea­tures lea­ding-edge HBM2 tech­no­lo­gy which is capa­ble of trans­fer­ring tera­bytes of data every second, dou­bling the band­width-per-pin over the pre­vious gene­ra­ti­on HBM tech­no­lo­gy. HBM2 also enab­les much grea­ter capa­ci­ty at less than half the foot­print of GDDR5 memo­ry. Vega archi­tec­tu­re is opti­mi­zed for strea­ming very lar­ge data­sets and can work with a varie­ty of memo­ry types with up to 512TB of vir­tu­al address space.
  • Next-gene­ra­ti­on geo­me­try pipe­line: Today’s games and pro­fes­sio­nal app­li­ca­ti­ons make use of incredi­b­ly com­plex geo­me­try enab­led by the extra­or­di­na­ry increa­se in the reso­lu­ti­ons of data acqui­si­ti­on devices.  The hund­reds of mil­li­ons of poly­gons in any given frame have mes­hes so den­se that the­re are often many poly­gons being ren­de­red per pixel. Vega’s next-gene­ra­ti­on geo­me­try pipe­line enab­les the pro­grammer to extract incredi­ble effi­ci­en­cy in pro­ces­sing this com­plex geo­me­try, while also deli­vering more than 200% of the through­put-per-clock over pre­vious Rade­on archi­tec­tures.[i] It also fea­tures impro­ved load-balan­cing with an intel­li­gent workload dis­tri­bu­tor to deli­ver con­sis­tent per­for­mance.
  • Next-gene­ra­ti­on com­pu­te engi­ne: At the core of the Vega archi­tec­tu­re is a new, next-gene­ra­ti­on com­pu­te engi­ne built on fle­xi­ble com­pu­te units that can natively pro­cess 8-bit, 16-bit, 32-bit or 64-bit ope­ra­ti­ons in each clock cycle.[ii] The­se com­pu­te units are opti­mi­zed to attain signi­fi­cant­ly hig­her fre­quen­ci­es than pre­vious gene­ra­ti­ons and their sup­port of varia­ble data­ty­pes makes the archi­tec­tu­re high­ly ver­sa­ti­le across workloads.
  • Advan­ced pixel engi­ne: The new Vega pixel engi­ne employs a Draw Stream Bin­ning Ras­te­ri­zer, desi­gned to impro­ve per­for­mance and power effi­ci­en­cy. It allows for “fetch once, shade once” of pixels through the use of a smart on-chip bin cache and ear­ly cul­ling of pixels invi­si­ble in a final sce­ne. Vega’s pixel engi­ne is now a cli­ent of the onboard L2 cache, enab­ling con­s­i­derable over­head reduc­tion for gra­phics workloads which per­form fre­quent read-after-wri­te ope­ra­ti­ons.

GPU pro­ducts based on the Vega archi­tec­tu­re are expec­ted to ship in the first half of 2017.

Such state­ments are sub­ject to cer­tain known and unknown risks and uncer­tain­ties, many of which are dif­fi­cult to pre­dict and gene­ral­ly bey­ond AMD’s con­trol, that could cau­se actu­al results and other future events to dif­fer mate­ri­al­ly from tho­se expres­sed in, or implied or pro­jec­ted by, the for­ward-loo­king infor­ma­ti­on and state­ments. Mate­ri­al fac­tors that could cau­se actu­al results to dif­fer mate­ri­al­ly from cur­rent expec­ta­ti­ons inclu­de, without limi­ta­ti­on, the fol­lo­wing: Intel Corporation’s domi­nan­ce of the micropro­ces­sor mar­ket and its aggres­si­ve busi­ness prac­tices may limit AMD’s abi­li­ty to com­pe­te effec­tively; AMD is par­ty to a wafer sup­ply agree­ment with GLOBALFOUNDRIES Inc. (GF) with obli­ga­ti­ons to manu­fac­tu­re pro­ducts at GF with cer­tain excep­ti­ons. If GF is not able to satis­fy AMD’s manu­fac­tu­ring requi­re­ments, its busi­ness could be adver­se­ly impac­ted; AMD reli­es on third par­ties to manu­fac­tu­re its pro­ducts, and if they are unab­le to do so on a time­ly basis in suf­fi­ci­ent quan­ti­ties and using com­pe­ti­ti­ve tech­no­lo­gies, AMD’s busi­ness could be mate­ri­al­ly adver­se­ly affec­ted; fail­u­re to achie­ve expec­ted manu­fac­tu­ring yiel­ds for AMD’s pro­ducts could nega­tively impact its finan­ci­al results; the suc­cess of AMD’s busi­ness is depen­dent upon its abi­li­ty to intro­du­ce pro­ducts on a time­ly basis with fea­tures and per­for­mance levels that pro­vi­de value to its custo­mers while sup­porting and coin­ci­ding with signi­fi­cant indus­try tran­si­ti­ons; if AMD can­not gene­ra­te suf­fi­ci­ent reve­nue and ope­ra­ting cash flow or obtain exter­nal finan­cing, it may face a cash short­fall and be unab­le to make all of its plan­ned invest­ments in rese­arch and deve­lop­ment or other stra­te­gic invest­ments; the loss of a signi­fi­cant custo­mer may have a mate­ri­al adver­se effect on AMD; AMD’s rece­ipt of reve­nue from its semi-custom SoC pro­ducts is depen­dent upon its tech­no­lo­gy being desi­gned into third-par­ty pro­ducts and the suc­cess of tho­se pro­ducts; glo­bal eco­no­mic uncer­tain­ty may adver­se­ly impact AMD’s busi­ness and ope­ra­ting results; the mar­kets in which AMD’s pro­ducts are sold are high­ly com­pe­ti­ti­ve; AMD may not be able to gene­ra­te suf­fi­ci­ent cash to ser­vice its debt obli­ga­ti­ons or meet its working capi­tal requi­re­ments; AMD has a sub­stan­ti­al amount of indeb­ted­ness which could adver­se­ly affect its finan­ci­al posi­ti­on and pre­vent it from imple­men­ting its stra­te­gy or ful­fil­ling its con­trac­tu­al obli­ga­ti­ons; the agree­ments gover­ning AMD’s notes and the secu­red revol­ving line of credit (Secu­red Revol­ving Line of Credit) impo­se restric­tions on AMD that may adver­se­ly affect its abi­li­ty to ope­ra­te its busi­ness; uncer­tain­ties invol­ving the orde­ring and ship­ment of AMD’s pro­ducts could mate­ri­al­ly adver­se­ly affect it; the demand for AMD’s pro­ducts depends in part on the mar­ket con­di­ti­ons in the indus­tries into which they are sold. Fluc­tua­ti­ons in demand for AMD’s pro­ducts or a mar­ket decli­ne in any of the­se indus­tries could have a mate­ri­al adver­se effect on its results of ope­ra­ti­ons; AMD’s abi­li­ty to design and intro­du­ce new pro­ducts in a time­ly man­ner is depen­dent upon third-par­ty intel­lec­tu­al pro­per­ty; AMD depends on third-par­ty com­pa­nies for the design, manu­fac­tu­re and sup­ply of mother­boards, soft­ware and other com­pu­ter plat­form com­pon­ents to sup­port its busi­ness; if AMD loses Micro­soft Corporation’s sup­port for its pro­ducts or other soft­ware ven­dors do not design and deve­lop soft­ware to run on AMD’s pro­ducts, its abi­li­ty to sell its pro­ducts could be mate­ri­al­ly adver­se­ly affec­ted; and AMD’s reli­an­ce on third-par­ty dis­tri­bu­tors and Add-in-Board part­ners sub­jects it to cer­tain risks. Inves­tors are urged to review in detail the risks and uncer­tain­ties in AMD’s Secu­ri­ties and Exchan­ge Com­mis­si­on filings, inclu­ding but not limi­ted to AMD’s Quar­ter­ly Report on Form 10-Q for the quar­ter ended Sep­tem­ber 24, 2016.
