A zahiri, duk motherboards suna sanye take da Kaby Lake, ya kamata su iya kula da Optane Memory. LED-backlight, ma taka babban rawa a cikin motherboard 200 jerin: shi hana kawai 'yan model a kowane farashin category.

yawan aiki

Kamar yadda ka yi tsammanin, babu riba a yi ba. A cewar mai amfani feedback, 3-GHz processor Kaby Lake i7-7700K aiki kamar wancan Core i7-6700K processor tare da agogo mita 3 GHz (tare da hyperthreading kashe). Iyakar abin da bambanci ne memory goyon baya. Idan Skylake jituwa tare da DDR4-2133, da Kaby Lake - tare da DDR4-2400, amma yana da kadan sakamako a kan kusan dukkan asowar.

ikon amfani

Daya babbar amfani da processor Kaby Lake - wannan mita tare da kasa da ikon, ko mafi girma a wannan ikon kamar yadda idan aka kwatanta da Skylake. i7-7700K goyon bayan turbo 4.5 GHz a thermal ikon 91 watts. A duk gwajin sarrafawa Kaby Lake ko waste a lokacin manual amfani mafi kusa ga lasafta daya, amma yawanci yawa overestimates bada CPU ƙarfin lantarki da ake bukata domin barga aiki na guntu.

hanzari

A cewar mai amfani feedback, da ji na kara Agogon mita Kaby Lake ya canza godiya ga sabon AVX biya diyya, wanda yake a cikin BIOS na kowane motherboard Z270. An sani cewa AVX umarnin su ne detrimental don tarwatsa, rage zaman lafiya da kuma impeding gabatarwa code ba tare da AVX. Yanzu mai amfani iya amfani da wani bambanci (misali, -10x), wanda zai rage factor cewa ya auku AVX tawagar. Wannan yana nufin cewa a lokacin da hanzari Kaby Lake processor zuwa 4.8 GHz AVX-shift 8x AVX umurnin za a kashe a 4.0GHz, allocating kasa da zafi da tsare zaman lafiya.

A cewar masu amfani, da mita 4.8 GHz AVX shi ne sauƙin achievable ko da wani m ƙarfin lantarki. і7-7700K kai 4.9 GHz biya diyya AVX -10, kuma і5-7600K - 5.0 GHz, koda lokacin da AVX.

By kuma manyan hanzari і7-7700K daga 4.2 zuwa 4.8 GHz m amfanin aikata ba. Bambanci a cikin 600 MHz yayi dace 13-14% karuwa a yawan aiki, wanda shi ne ba yawa. Duk da haka, idan akai la'akari da profile guntu ƙarfin lantarki, da mita 4.5 GHz samar da kyau zafin jiki da kuma irin ƙarfin lantarki, har yanzu wucewa і7-4790K ko і7-6600K.

gwajin sakamakon

Ga mai amfani da feedback, da kwatanta Kaby Lake processor tabbatar da cewa kusan kashi Core і7-7700K a kowane gwajin (fãce kaɗan, inda і7-5775C har yanzu mafi saboda 128MB eDRAM).

Core і5-7600K aiki kusan guda, sai dai da hanyar al'amura da kananan yawan gudana (misali, a cikin ray burbushi), amma a lokacin da yin yau da kullum ayyuka da processor, ba shakka, a wata hanya baya. Core і5-7600K saboda rashin ci gaban ІRS ma і5-6600K ne na asali ba, fãce, 'yan karin megahertz. Yana accelerates da processor ne mai kyau - ta zazzabi da yawa fiye da і7-7700K, amma kome sabon abu, ya ba.

Elephant a cikin dakin, duk da haka, shi ne Core і3-7350K. Tare da farashin $ 159 shi ne kawai 11-dollar ta Core і5-7400, wanda halin kaka $ 170, amma yana da 2 biyu cikakken tsakiya, ko da yake a wata ƙananan mita (3 GHz zuwa 4.2 GHz).

Yana yana da sabon Intel gine a milestone?

Domin mafi part Kaby Lake ba ya bayar da yawa canji. Support Optane memory ne da, amma sauran - dai kawai wani motsi a cikin ikon da kuma yadda ya dace kwana. A kuzari a 3.0 GHz a cikin shekara da ta gabata, a yanzu na samar da 3.3 GHz, wanda ke nufin ceton lokaci ciyar a kan aikin yi ko ikon tanadi. Speed Shift v2 - gaske kyau alama, amma shi an iyakance shi zuwa masu amfani a cikin Windows 10. More ban sha'awa shi ne a sa na sabon rinjãya (ALC1220, E2500, Aquantia). Optimization ne ganin darajarsa gine ne ba abin mamaki ba, amma na samar da wani 10% karuwa a yadda ya dace.
