AMD & NVIDIA Next-Gen Flagship GPUs Tsatanetsatane: RDNA 3 Radeon RX 7900 XT Yokhala Ndi 15360 Cores, Ada Lovelace GeForce RTX 4090 Yokhala Ndi 18432 Cores

Zodziwika bwino za m'badwo wotsatira wa AMD RDNA 3 yoyendetsedwa ndi Radeon RX 7900 XT & NVIDIA Ada Lovelace yoyendetsedwa ndi makadi ojambula a GeForce RTX 4090 afotokozedwanso mwatsatanetsatane. Mphekesera zimachokera Alireza yemwe wakhala akulemba zambiri zokhudzana ndi zida zomwe zikubwera monga CPUs ndi GPUs pa Twitter feed kwa kanthawi tsopano.

AMD RDNA 3 yoyendetsedwa ndi Navi 31 ndi Ada Lovelace-powered AD102 GPUs akuyembekezeka kubweretsa kuwongolera kwakukulu komanso kukhala tchipisi zanjala kwambiri zomwe zidapangidwapo. Pomwe NVIDIA ikufuna njira yopangira monolithic ndi kapangidwe kake ka Ada Lovelace, AMD igwiritsa ntchito kapangidwe kathunthu ka MCM komwe idatsogola kale ndikukhazikitsa mndandanda wa CDNA 2 powered MI200 'Aldebaran'. AMD idzagwiritsa ntchito ukadaulo womwewo wa MCM pamasewera omaliza & ma GPU amasewera tsopano. Ndiye tiyeni tikambirane za mphekesera zaposachedwa kwambiri zomwe tapeza kuchokera kwa wotulutsa:

AMD Radeon RX 7900 XT Graphics Card - RDNA 3 Powered Navi 31 Flagship GPU

AMD Navi 31 GPU, chipangizo chamtundu wa RDNA 3, chingapangitse khadi lazithunzi la Radeon RX 7900 XT. Tamva kuti AMD igwetsa CU (Compute Units) m'malo mwa WGP (Work Group processors) pamtundu wake wotsatira wa RDNA 3 GPUs. Popeza Navi 31 ndi MCM GPU, idzakhala ndi ma IP awiri ofunika, GCD (Graphics Core Die) yotengera ndondomeko ya TSMC ya 5nm ndi MCD (Multi-Cache Die) yotengera ndondomeko ya TSMC 6nm. Mphekesera zam'mbuyomu zikuwonetsa kuti AMD yatero idatulutsa kale Navi 31 GPU yake kufa.

Kukonzekera kwa Navi 31 GPU komwe kukuwonetsedwa pano kumakhala ndi ma GCD awiri (Graphics Core Die) ndi MCD imodzi (Multi-Cache Die). GCD iliyonse ili ndi 3 Shader Engines (6 yonse) ndipo Shader Engine iliyonse ili ndi 2 Shader Arrays (2 pa SE / 6 pa GCD / 12 yonse). Shader Array iliyonse imakhala ndi ma WGP 5 (10 pa SE / 30 pa GCD / 60 yonse) ndipo WGP iliyonse imakhala ndi mayunitsi 8 a SIMD32 okhala ndi 32 ALUs (40 SIMD32 pa SA / 80 pa SE / 240 pa GCD / 480 yonse). Mayunitsi a SIMD32 awa amaphatikiza kupanga ma cores 7,680 pa GCD ndi ma cores 15,360 onse.

Mwanzeru, GPU ikuyembekezeka kukhala ndi liwiro la wotchi ya 2.4 - 2.5 GHz yomwe imayika magwiridwe ake amalingaliro pafupifupi 75 TFLOPs (FP32). Uku ndikuwongolera kwamisala kwa 226% vs khadi yazithunzi ya Radeon RX 6900 XT.

Navi 31 (RDNA 3) MCD idzalumikizidwa ndi ma GCD apawiri kudzera mum'badwo wotsatira wa Infinity Fabric interconnect ndikuwonetsa 256-512 MB ya Infinity Cache. GPU iliyonse iyeneranso kukhala ndi maulalo 4 olumikizira kukumbukira (32-bit). Ndiwo olamulira a 8 32-bit kukumbukira mabasi a 256-bit. Zanenedwa kuti khadiyo ikhala ndi 32 GB ya GDDR6 memory yomwe ikuyenda pa liwiro la 18 Gbps & yomwe imapereka mpaka 576 GB/s bandwidth. Mphekesera zina zomwe zidawoneka posachedwa zikuwonetsa kuti AMD adzakhala akugwiritsa ntchito ukadaulo wa 3D Infinity Cache pamzere wake wa RDNA 3 womwe ungaphatikizepo cache yatsopano m'mapaketi oyimirira pa GPUs, mofanana ndi momwe Tchipisi za Vermeer-X zidzasunga L3 cache pa CCD.

AMD RDNA GPU (Generational Comparison) Yoyamba:

NVIDIA GeForce RTX 4090 Graphics Card - Ada Lovelace Powered AD102 Flagship GPU

Kutengera mphekesera zam'mbuyomu, pakhala kunong'onezana kuti NVIDIA igwiritsa ntchito njira ya TSMC's N5 (5nm) ya Ada Lovelace GPUs. Izi zikuphatikizanso AD102 SKU nayonso yomwe ikhala yopangidwa ndi monolithic. Mu tweet yake yaposachedwa yomwe imakamba za kasinthidwe ka GPU, AD102 GPU akuti imakhala ndi liwiro la wotchi yokwera ngati 2.5 GHz (2.3 GHz average boost). Titter yeniyeni imati wotchi ya GPU ya Ada Lovelace 'AD102' ikhoza kukhala 2.3 GHz kapena kupitilira apo ndiye tiyeni titenge izi ngati zoyambira komanso zomwe zidatsitsidwa kale kuti tidziwe komwe ntchitoyi ikuyenera kugwera.

NVIDIA AD102 "ADA GPU" ikuwoneka kuti ili ndi 18432 CUDA Cores kutengera zoyambira (zomwe zingasinthe), zokhala mkati mwa mayunitsi a 144 SM. Izi ndi pafupifupi kuwirikiza kawiri ma cores omwe amapezeka ku Ampere omwe anali kale gawo lalikulu kuchokera ku Turing. Kuthamanga kwa wotchi ya 2.3-2.5 GHz kungatipatse mpaka 85 mpaka 92 TFLOPs of compute performance (FP32). Izi ndizoposa kawiri ntchito ya FP32 ya RTX 3090 yomwe ilipo yomwe imanyamula 36 TFLOPs ya FP32 compute power.

Kudumpha kwa 150% kumawoneka kwakukulu koma wina ayenera kukumbukira kuti NVIDIA idalumpha kale mu manambala a FP32 m'badwo uno ndi Ampere. Ampere GA102 GPU (RTX 3090) imapereka ma TFLOP 36 pomwe Turing TU102 GPU (RTX 2080 Ti) idapereka ma TFLOP 13. Ndizoposa 150% kuwonjezeka kwa FP32 Flops koma masewera enieni akuwonjezeka kwa RTX 3090 pafupifupi pafupifupi 50-60% mofulumira kuposa RTX 2080 Ti. Chifukwa chake chinthu chimodzi chomwe sitiyenera kuyiwala ndichakuti Flops safanana ndi masewera a GPU masiku ano. Kuphatikiza apo, sitikudziwa ngati 2.3-2.5 GHz ndiye mphamvu yapakati kapena kukwera pachimake ndi tanthauzo lakale kuti pangakhale kuthekera kokulirapo kwa AD102.

Kupatula apo, wotsitsayo akunenanso kuti NVIDIA GeForce RTX 40 flagship idzakhalabe ndi mawonekedwe a basi 384-bit, ofanana ndi RTX 3090. Chosangalatsa ndi chakuti wotayitsayo amatchula G6X kutanthauza kuti NVIDIA sidzasuntha zatsopano zokumbukira mpaka Ada Lovelace ndikugwiritsa ntchito mapini apamwamba a G6X a 21 Gbps pamakadi ake am'badwo wotsatira tisanawone mulingo watsopano (mwachitsanzo GDDR7). Khadiyo idzakhala ndi 24 GB ya kukumbukira kotero kuti tikhoza kuyembekezera ma module a 16Gb DRAM kapena mbali ziwiri za 8Gb DRAM.

NVIDIA CUDA GPU (RUMORED) Yoyamba:

Ma NVIDIA Ada Lovelace GPUs adzapatsa mphamvu makadi ojambula a GeForce RTX 40 a m'badwo wotsatira omwe azipita patsogolo ndi makadi ojambula a AMD a RDNA 3 a Radeon RX 7000. Pali malingaliro ena okhudza kugwiritsa ntchito MCM ndi NVIDIA. Hopper GPU, yomwe imayang'ana kwambiri gawo la Datacenter & AI, ndi akuti akutuluka posachedwa ndipo izikhala ndi kamangidwe ka MCM. NVIDIA sikhala ikugwiritsa ntchito kapangidwe ka MCM pa Ada Lovelace GPUs kotero kuti azisunga mawonekedwe amtundu wa monolithic.

Ndi ma GPU amtundu uti omwe mukuyembekezera kwambiri?

• AMD RDNA 3 (Navi 3X Radeon RX GPUs)
• NVIDIA Ada Lovelace (GeForce RTX GPUs)
• Intel ARC Alchemist (ARC Graphics Cards)
