Cov lus xaiv tshwj xeeb ntawm cov tiam tom ntej AMD RDNA 3 powered Radeon RX 7900 XT & NVIDIA Ada Lovelace powered GeForce RTX 4090 daim npav duab tau hais meej dua ib zaug. Cov lus xaiv los ntawm Greymon 55 leej twg tau nquag tshaj tawm cov ntsiab lus hais txog kev kho vajtse tom ntej xws li CPUs thiab GPUs dhau ntawm nws Twitter pub rau ib pliag tam sim no.
AMD RDNA 3 & NVIDIA Ada Lovelace GPU Powered Next-Gen Flagship Radeon RX 7900 XT & GeForce RTX 4090 Graphics phaib nthuav dav
AMD RDNA 3 powered Navi 31 thiab Ada Lovelace-powered AD102 GPUs xav tias yuav coj kev txhim kho loj thiab tseem yuav yog cov chips tshaib plab tshaj plaws uas tau ua. Thaum NVIDIA tab tom npaj rau txoj hauv kev monolithic nrog nws Ada Lovelace architecture, AMD yuav siv tag nrho MCM tsim uas nws twb tau coj ua thawj coj nrog kev tshaj tawm ntawm CDNA 2 powered MI200 series 'Aldebaran'. AMD yuav siv tib lub tshuab MCM rau cov neeg siv khoom kawg & gaming GPUs tam sim no. Yog li cia peb tham txog qhov tseeb rumored specifications uas peb tau txais los ntawm cov leaker:

AMD Radeon RX 7900 XT Graphics Card - RDNA 3 Powered Navi 31 Flagship GPU
AMD Navi 31 GPU, tus flagship RDNA 3 nti, yuav siv lub zog tom ntej-gen Radeon RX 7900 XT daim npav duab. Peb tau hnov tias AMD yuav tso CU (Compute Units) hauv kev pom zoo ntawm WGP (Cov Neeg Ua Haujlwm Pab Pawg Ua Haujlwm) ntawm nws cov RDNA 3 GPUs tom ntej. Txij li Navi 31 yog MCM GPU, nws yuav muaj ob lub IPs tseem ceeb, GCD (Graphics Core Die) raws li TSMC's 5nm txheej txheem thiab MCD (Multi-Cache Die) raws li TSMC 6nm txheej txheem node. Cov lus xaiv dhau los qhia tias AMD muaj twb tapping nws Navi 31 GPU tuag.
Lub Navi 31 GPU configuration qhia ntawm no nta ob GCD's (Graphics Core Tuag) thiab ib qho MCD (Multi-Cache Tuag). Txhua GCD muaj 3 Shader Cav (6 nyob rau hauv tag nrho) thiab txhua Shader Cav muaj 2 Shader Arrays (2 ib SE / 6 ib GCD / 12 nyob rau hauv tag nrho). Txhua Shader Array yog tsim los ntawm 5 WGPs (10 ib SE / 30 ib GCD / 60 nyob rau hauv tag nrho) thiab txhua WGP nta 8 SIMD32 units nrog 32 ALUs (40 SIMD32 ib SA / 80 ib SE / 240 ib GCD / 480 nyob rau hauv tag nrho). Cov SIMD32 units ua ke los ua 7,680 cores ib GCD thiab 15,360 cores hauv tag nrho.
Kev ua tau zoo-ntseeg, GPU yuav tsum muaj lub moos ceev ntawm 2.4 - 2.5 GHz uas tso nws txoj kev ua haujlwm ntawm ib puag ncig 75 TFLOPs (FP32). Qhov no yog qhov kev ua tsis zoo 226% kev txhim kho vs Radeon RX 6900 XT daim npav duab.
Lub Navi 31 (RDNA 3) MCD yuav txuas mus rau dual GCD's ntawm ib tiam tom ntej Infinity Fabric interconnect thiab feature 256-512 MB ntawm Infinity Cache. Txhua GPU yuav tsum muaj 4 lub cim xeeb txuas txuas (32-ntsis). Qhov ntawd yog tag nrho ntawm 8 32-ntsis nco controllers rau 256-ntsis tsheb npav interface. Nws tau hais tias daim npav yuav muaj txog li 32 GB ntawm GDDR6 nco khiav ntawm 18 Gbps tus pin nrawm & uas xa mus txog 576 GB / s bandwidth. Lwm cov lus xaiv uas tau tshwm sim tsis ntev los no qhia tias AMD yuav siv 3D Infinity Cache technology ntawm nws cov RDNA 3 lineup uas yuav koom ua ke cov cache tshiab hauv cov kab ntsug ntsug ntawm GPUs, zoo ib yam li yuav ua li cas Vermeer-X chips yuav stack L3 cache hla CCD.

NVIDIA GeForce RTX 4090 Graphics Card - Ada Lovelace Powered AD102 Flagship GPU
Raws li cov lus xaiv dhau los, tau hais lus ntxhi tias NVIDIA yuav siv TSMC's N5 (5nm) cov txheej txheem rau nws Ada Lovelace GPUs. Qhov no suav nrog AD102 SKU ib yam nkaus uas yuav yog tus qauv tsim monolithic nkaus xwb. Hauv nws qhov tseeb tweet uas hais txog qhov tshwj xeeb GPU teeb tsa, AD102 GPU tau hais kom muaj lub moos ceev kom siab li 2.5 GHz (2.3 GHz nruab nrab txhawb nqa). Cov tweet tshwj xeeb tau hais tias GPU moos rau Ada Lovelace 'AD102' tuaj yeem yog 2.3 GHz lossis ntau dua yog li cia peb coj qhov ntawd los ua qhov hauv paus thiab yav dhau los cov lus tshwj xeeb los txiav txim seb qhov kev ua tau zoo yuav tsum tsaws.
NVIDIA AD102 "ADA GPU" zoo li muaj 18432 CUDA Cores raws li cov kev qhia ua ntej (uas tuaj yeem hloov pauv), nyob hauv 144 SM units. Qhov no yog yuav luag ob zaug ntawm cov cores tam sim no hauv Ampere uas twb yog ib kauj ruam loj ntawm Turing. Lub 2.3-2.5 GHz moos ceev yuav ua rau peb mus txog 85 txog 92 TFLOPs ntawm kev ua tau zoo (FP32). Qhov no yog ntau tshaj ob zaug ntawm FP32 kev ua tau zoo ntawm RTX 3090 uas twb muaj lawm uas ntim 36 TFLOPs ntawm FP32 suav lub zog.
150% kev ua tau zoo dhia zoo li loj tab sis ib qho yuav tsum nco ntsoov tias NVIDIA twb tau dhia loj hauv FP32 tus lej tiam no nrog Ampere. Lub Ampere GA102 GPU (RTX 3090) muaj 36 TFLOPs thaum Turing TU102 GPU (RTX 2080 Ti) muab 13 TFLOPs. Qhov ntawd yog ntau dua 150% nce hauv FP32 Flops tab sis qhov kev ua si hauv ntiaj teb tiag tiag nce rau RTX 3090 qhov nruab nrab ntawm ib ncig ntawm 50-60% sai dua RTX 2080 Ti. Yog li ib yam uas peb yuav tsum tsis txhob hnov qab yog tias Flops tsis sib npaug GPU gaming kev ua tau zoo hnub no. Tsis tas li ntawd, peb tsis paub yog tias 2.3-2.5 GHz yog qhov nruab nrab boost los yog lub ncov boost nrog lub ntsiab lus qub uas tuaj yeem muaj peev xwm ntau dua rau AD102.
Ib cag ntawm qhov ntawd, tus leaker tseem hais tias NVIDIA GeForce RTX 40 flagship yuav khaws 384-ntsis tsheb npav interface, zoo ib yam li RTX 3090. Dab tsi nthuav yog tias tus leaker hais txog G6X uas txhais tau tias NVIDIA yuav tsis txav mus rau ib qho. tus qauv cim xeeb tshiab kom txog rau thaum tom qab Ada Lovelace thiab siv tus pin-speeds ntawm G6X ntawm 21 Gbps rau nws cov phaib tiam tom ntej ua ntej peb pom tus qauv tshiab (xws li GDDR7). Daim npav yuav muaj 24 GB ntawm lub cim xeeb yog li peb tuaj yeem cia siab tias yuav muaj ib sab 16Gb DRAM lossis dual-sided 8Gb DRAM modules.

NVIDIA Ada Lovelace GPUs yuav ua lub zog rau tiam tom ntej GeForce RTX 40 daim npav duab uas yuav mus rau lub taub hau nrog AMD's RDNA 3 raws li Radeon RX 7000 series graphics phaib. Tseem muaj qee qhov kev xav txog kev siv MCM los ntawm NVIDIA. Lub Hopper GPU, uas yog tsom rau ntawm Datacenter & AI ntu, yog liam taping tawm sai sai no thiab yuav nthuav tawm MCM architecture. NVIDIA yuav tsis siv MCM tsim ntawm nws Ada Lovelace GPUs yog li lawv yuav khaws cov qauv monolithic.
