- I-Xe3 iqala nge-Panther Lake ngama-cores angu-4 kuye kwayi-12 kanye nama-RT angu-12 kunketho enekhono kakhulu
- Kufika ku-16MB L2, 96MB XMX, kanye nokweqa ku-iGPU cishe okungu-50% uma kuqhathaniswa ne-Xe2
- Kufika ku-120 TOPS ku-GPU kanye ne-180 TOPS kuhlanganiswe ne-NPU 5 ne-CPU
- Ingxenye ye-GPU ikhiqizwa ngaphandle (nge-Foveros), namahemuhemu e-TSMC ye-12-core variant.
I-Intel ilungiselela ukwethulwa kwamalaptop ayo alandelayo ngePanther Lake kanye nesizukulwane esisha sezithombe ezihlanganisiwe: Xe3. Inkampani iqinisekisa ukuthi lokhu kukhuphuka kuzosungulwa ibha engakaze ibonwe ye-iGPUs, into eza ngemva kweminyaka eminingana yokulungisa kahle izakhiwo zayo nezishayeli.
Ephepheni, i-Xe3 ikala kusuka kuma-graphic cores angu-4 kuye kwayi-12, okuhlanganisa nokufika 16 MB L2 inqolobane, 96 XMX izinjini kanye 12 ray tracing amayunithi ekucushweni kwayo okunekhono kakhulu, futhi ithembisa ukwanda okucacile kokusebenza kahle ngenxa yentuthuko yangaphakathi kanye nenqubo ye-Intel 18A yebhulokhi yekhompyutha.
Iyini i-Intel Xe3 futhi izoqala kuphi?
I-Xe3 iyi-iteration yesithathu ye-Intel's graphics architecture yama-PC futhi izoqala ukudidiyelwa ku- I-Core Ultra Series 3 “Panther Lake”Izotholakala ekucushweni okuningana, kusukela kumamodeli ayisisekelo anama-Xe-cores angu-4 kuya kokuhlukile ano-12, aqondiswe kumakhompyutha angadingi i-GPU ezinikele.
I-Intel ifake i-Xe3 njengebhentshimakhi yomkhakha wonke, kodwa imininingwane emihle iyaphuma. Ukuvuza okungaguquki kubonisa ukuthi amabhentshimakhi anesijobelelo I-X (Ultra X9 ne-X7) izohlanganisa i-12 Xe3-core GPU ephelele, kuyilapho uchungechunge lwe-3X8 (isb., 388H) luzokhuphuka 10-12 ama-nuclei futhi i-3X6 izohlala ingaphansi kwe-10.
Uma kuqhathaniswa neLunar Lake, ehlanganisa inkumbulo ephaketheni, iPanther Lake iyayishiya leyo ndlela futhi ihlela kabusha ububanzi bayoIzinombolo ebezibhekisela phambilini kumthamo we-RAM ngabe seziphinde zasetshenziswa chaza izinga le-iGPU, ushintsho oluhloselwe ukwenza lula ukufunda ama-SKU.
Izinguquko zezakhiwo: ama-cores, ama-cache, nokulandelela ama-ray
I-Xe-core ngayinye yesizukulwane sesithathu iyengeza 8 512-bit vector izinjini kanye 8 XMX matrix izinjini, kanye nokuthuthukiswa kwenkumbulo eyabiwe (L1/SLM) ecishe ibe ngu-33% kanye nesabelo serejista esivumelana nezimo. I-Intel ibika kufika ku-25% imiluko eyengeziwe ngomongo ngamunye kanye ne-backend ebuyekeziwe.
Ukucushwa okuphezulu kuyengeza 16 MB L2 inqolobane ukunciphisa ukufinyelela kwememori kanye nokuzinzisa amazinga ozimele. Ama-microtest angaphakathi abika ukwanda okuphawulekayo ekufinyeleleni okuncane nokujula, kuyilapho ukuhlunga kwe-anisotropic nesivinini sokusebenza kwe-stencil kuphindwe kabili uma kuqhathaniswa nesizukulwane sangaphambilini.
Ibhulokhi yokulandela umsebe iphinde iguquke ibe namayunithi ayi-12 nokusekelwa kwawo isakhiwo esivumelanayo, ifuna ukusetshenziswa okungcono kwehadiwe ngaphansi kwemithwalo exubile. I-Intel iphinde iqondise kabusha izinsiza: izici zakudala ezifana ne-16x MSAA ziyalahleka uma kubhekwa izindlela zesimanje zokwakha kabusha. njengoba XeSS.
Enye into entsha efanele ukwesekwa kwe FP8 nge-dequantization kanye nalokho okubizwa ngokuthi ama-cooperative vectors (athuthukiswe nge-Microsoft), avumela ukuxuba ukusebenza kwe-matrix nokufiphaza ku-shader eyodwa ukuze kuhlanganiswe ama-algorithms e-AI epayipini lezithombe.
Ukusebenza, i-AI kanye nesikhulumi
Isithembiso sokusebenza siyafisa: I-Intel ilinganisela ukweqa kwe kufika ku-50% ku-iGPU vs. Xe2 ekucushweni okuqhathanisekayo, kanye nokusebenza kahle ngakunye kokuthuthukiswa kwe-watt phezu kwe-Arrow Lake-H. Umgomo uwukusondeza ukusebenza kwe-iGPU abazinikele abangenayo kumalaptops azacile futhi alula.
Emithwalo yemisebenzi ye-AI, ukungezwa kwama-accelerator kuletha inani eliphelele le-Panther Lake kufika ku-180 TOPS (cishe 10 TOPS kusuka ku-CPU ene-VNNI/AVX, 50 TOPS ku-NPU 5 kanye ne-120 TOPS ku-12-core Xe3 GPU), isabalalisa imisebenzi ngokohlobo lwayo ukuze iqukathe ukusetshenziswa nokubambezeleka.
Ukuhlanganisa futhi kuvela ohlangothini lwesofthiwe: I-Intel isebenza ohlelweni lwe ama-shader amafu ahlanganiswe ngaphambili eceleni kweMicrosoft kanye neValve ukunciphisa ama-stutters emidlalweni, kanye naku-XeSS nge-Multi-Frame Generation, kumademo, ekhiqiza kuze kufike amafreyimu amathathu "okwenziwa" kweqiniso ngalinye, njalo ngolawulo lwamamethrikhi avela kumshayeli.
Ekukhiqizeni, i-computing block isebenzisa I-Intel 18A, kuyilapho ingxenye ye-GPU—kuhlanganise ne-12 Xe3-core variant—ikhiqizwa ngaphandle futhi ihlanganiswe yi-Foveros; imithombo ehlukahlukene ikhomba ku-node ye-TSMC ethuthukisiwe yalokho kufa, njenge I-Intel 3 yenguqulo engu-4-core.
Ukuze isekele le GPU, i-Intel ihlela kabusha ukusatshalaliswa kwamandla: the Ama-E-cores nama-LP E-cores Bathatha imisebenzi yokusiza ukukhulula isabelomali esishisayo se-iGPU ezimweni zemidlalo, inkampani ethi inikeza ukusebenza okungaguquki ngaphakathi kwama-TDP aqukethwe.
Ukuqinisekiswa eyaziwa ngezinjongo zokuqondisa, ingashintshwa kuze kukhishwe ngokusemthethweni:
- 12 Xe3 cores: 12 RT, 96 XMX, 16 MB L2; gxila kumalaptop angenayo i-dGPU
- 3X8 series (isb., 388H): 10–12 Xe3 cores kuye nge-SKU
- 3X6 Series: ngaphansi kuka-10 Xe3-cores
- 4 Xe3-cores: 4 RT, 32 XMX, 4 MB L2; inketho eyisisekelo
Uma ukuvuza kwe-Intel kanye nokuvuza okuqine kakhulu kuqinisekiswa, i-Xe3 ibumba i-pivot yayo enkulu kakhulu okwamanje kumahluzo ahlanganisiwe: amayunithi amaningi, Ama-caches anwetshiwe kanye nokuxhumana okungcono kwe-AI, esekelwa ukuthuthukiswa kokusebenza kahle namathuluzi esofthiwe adizayinelwe ukushelela izingqinamba ezivamile kumageyimu nokudala.
