Apple yawulula banja lake latsopano la Apple Silicon chipset pamwambo wa “Let Loose”. Apple M4 idayambitsidwa ndi OLED iPad Pro yatsopano. Mzere wa iPad Pro walumpha mwachindunji kuchokera ku Apple M2 kupita ku Apple M4. Chifukwa chake m’nkhaniyi, tikufanizira Apple M4 ndi M2 kuti tiwone kusiyana kwawo mu CPU, GPU, ndi Neural Engine. Takambirananso za bandwidth ya kukumbukira ndi kusintha kwina kwa AI pa M4. Pachidziwitso chimenecho, tiyeni tiyambe.
Tasintha ma frequency a Apple M4 kutengera mindandanda yaposachedwa ya Geekbench. Kuphatikiza apo, tawonjezera mphambu ya Geekbench ya Apple M4 chipset pakuwunika kwathu.
Apple M4 vs M2: Kuyerekeza Kwapadera
Nayi mafotokozedwe ofananira pakati pa Apple M4 ndi M2. Yang’anani kuti mumvetsetse kusiyana pakati pa ma chipsets awiriwa.
Apple M4 vs M2: CPU
Kuyambira ndi CPU poyamba, Apple M4 imapangidwa TSMC ya 2nd-gen 3nm process node zomwe akuti zimagwira ntchito bwino. Imanyamula ma transistors opitilira 28 biliyoni. Apple M4 CPU ya iPad Pro imapezeka m’mitundu iwiri: 9 CPU cores ndi 10 CPU cores.
Mumapeza magwiridwe antchito 3 ndi ma cores 6 mu mtundu woyamba ndi magwiridwe antchito 4 ndi ma cores 6 ochita bwino mumitundu yachiwiri. Ndipo Apple M4 CPU ili ndi wotchi yamphamvu ya 4.4GHz, yokwera kwambiri kuposa liwiro la wotchi ya Apple M2 ndi M3 CPU.
Kuphatikiza apo, Apple yadzaza mtundu wotsatira ML ma accelerators mu Apple M4 CPU. Itha kuthandizira ntchito zokhudzana ndi AI, kugwira ntchito limodzi ndi Neural Engine.
Kumbali ina, Apple M2 CPU imapangidwa pa TSMC’s 5nm process node ndipo imanyamula ma transistors pafupifupi 20 biliyoni. Ili ndi ma cores 8 a CPU, opangidwa ndi 4 magwiridwe antchito ndi ma cores 4, ndipo imakhala ndi 3.49GHz. Malinga ndi Apple, M4 CPU ili mpaka 50% mwachangu (1.5x) kuposa M2 CPU.
Ngati tilingalira za kuchuluka kwa Geekbench kwa Apple M4, zikuwoneka kuti Apple M4 ili ndi CPU yamphamvu. Imaposa Apple M2 ndi malire akulu.
Apple M4 vs M2: GPU
Mu dipatimenti ya GPU, Apple yagwira ntchito yomanga ya m’badwo wotsatira wa GPU yomwe idayambitsidwa ndi chip M3. Apple M4 imabwera ndi 10 GPU cores ndipo imathandizira zinthu ngati dynamic caching kuti mugwiritse ntchito bwino GPU.
Kuphatikiza apo, kwa nthawi yoyamba, mndandanda wa iPad umakulitsidwa ndi hardware Ray Tracing ndi HW-accelerated Mesh Shading, chifukwa cha Apple M4 GPU yamphamvu. Ray Tracing amatha kupereka mithunzi yeniyeni ndi zowonetsera m’masewera kuti mukhale ndi masewera olimbitsa thupi.
Apple M2 ilinso ndi 10 GPU cores koma ilibe izi. Apple imati Apple M4 GPU imapereka mpaka 4x ntchito yabwino kuposa M2 GPU. Ndipo pakuchita-per-watt, Apple M4 GPU imatha kutulutsa magwiridwe antchito apamwamba a M2 pomwe ikugwiritsa ntchito theka la mphamvu.
Apple M4 vs M2: Neural Engine
Kubwera ku Neural Engine, Apple yasintha kwambiri 16-core Neural Engine pa M4. Ngakhale atanyamula ma cores omwewo, ndiyothamanga kwambiri komanso yachangu kuposa M2 Neural Engine. M4 Neural Engine imatha kuperekera mpaka 38 thililiyoni ntchito pa sekondi iliyonse (TOPS) pomwe M2 Neural Engine yakale imatha kukwera mpaka 15.8 TOPS.
Ndikugwira ntchito ndi ma accelerator a ML mu CPU ndi m’badwo wotsatira wa GPU, M4 Neural Engine imapereka magwiridwe antchito osaneneka. Apple akuti imatha kuyendetsa Generative AI yamphamvu komanso Kufalikira kwamitundu komweko pa chipangizo.
Apple M4 vs M2: Bandwidth Memory ndi Zina
Pomaliza, potengera kukumbukira bandwidth, Apple yanyamula kukumbukira pang’ono pa Apple M4. Ikhoza kupereka liwiro mpaka 120 GBps ndi bandwidth ndi chimodzimodzi kudutsa mitundu 8GB ndi 16GB. Apple M2 imakhala ndi kukumbukira kwa LPDDR5 komwe kumapereka liwiro la 100 GBps pamitundu yoyambira. Chimphona cha Cupertino sichinaulule mtundu wa kukumbukira kwa Apple M4 chip.
Kupatula apo, Media Engine pa Apple M4 imabweretsa HW-imathandizira Av1 decode kuthandizira kuwonera makanema apamwamba kwambiri. Ilibebe encoding ya AV1 yofulumira ya HW. Ndipo mumapeza chithandizo cha codec cha kanema cha ProRes, H.264, ndi HEVC pa chipsets zonse ziwiri.
Chigamulo
apulosi akuti M4 chipset ndi “chip champhamvu kwambiri” komanso mwachangu kwambiri kuposa chipset cha M2 ndikujambula mphamvu zochepa. Poyerekeza ndi chipangizo cha M2, Apple M4 kwenikweni zikuwoneka ngati kukweza kwakukulu. Mumapeza 1.5x ntchito yabwino ya CPU; 4x magwiridwe antchito a GPU abwino, 2x kuwongolera magwiridwe antchito a Neural Engine, komanso liwiro la kukumbukira pang’ono.
Ngakhale poyerekeza ndi Apple M3, kusiyana kwa magwiridwe antchito ndikokwanira. Tili ndi chidwi ndi kugwiritsa ntchito mphamvu Ziwerengero za M4 monga zikuwoneka ngati chipset chogwira ntchito kwambiri. Tikayika manja athu pa iPad Pro yatsopano, tidzayiyesa ndikugawana zowerengera za Apple M4 chip. Choncho khalani nafe!
