G-Sync nta
G-Sync saib feem ntau nqa tus nqi them vim tias lawv muaj cov khoom siv ntxiv uas xav tau los txhawb Nvidia's version ntawm kev hloov kho tshiab.Thaum G-Sync tshiab (Nvidia qhia nws hauv 2013), nws yuav raug nqi koj li $ 200 ntxiv los yuav G-Sync version ntawm ib qho zaub, tag nrho lwm yam nta thiab specs yog tib yam.Niaj hnub no, qhov sib txawv yog ze rau $ 100.
Txawm li cas los xij, FreeSync saib kuj tuaj yeem lees paub tias G-Sync Compatible.Daim ntawv pov thawj tuaj yeem tshwm sim rov qab, thiab nws txhais tau tias tus saib tuaj yeem khiav G-Sync hauv Nvidia qhov tsis muaj, txawm tias tsis muaj Nvidia 'tus tswv cuab scaler kho vajtse.Kev mus ntsib Nvidia lub vev xaib qhia cov npe ntawm cov saib uas tau lees paub los khiav G-Sync.Koj tuaj yeem ua haujlwm khiav G-Sync ntawm tus saib uas tsis yog G-Sync Compatible-certified, tab sis kev ua haujlwm tsis tau lees paub.

Muaj qee qhov kev lees paub uas koj tau txais nrog G-Sync saib uas tsis ib txwm muaj nyob hauv lawv cov FreeSync counterparts.Ib qho yog qhov muag plooj-txo (ULMB) nyob rau hauv daim ntawv ntawm lub teeb rov qab strobe.ULMB yog Nvidia lub npe rau cov yam ntxwv no;qee qhov FreeSync saib kuj muaj nws nyob rau hauv ib lub npe txawv.Thaum qhov no ua haujlwm nyob rau hauv qhov chaw ntawm Adaptive-Sync, ib txhia nyiam nws, perceiving nws muaj qis input lag.Peb tsis tuaj yeem lees paub qhov no hauv kev sim.Txawm li cas los xij, thaum koj khiav ntawm 100 thav duab ib ob (fps) lossis siab dua, qhov muag plooj feem ntau yog qhov tsis muaj teeb meem thiab cov tswv yim lag luam qis qis, yog li koj kuj tseem yuav khaws cov khoom nruj nrog G-Sync koom nrog.

G-Sync kuj tau lees tias koj yuav tsis pom tus ncej tsim kua muag txawm tias tus nqi qis tshaj.Hauv qab 30 Hz, G-Sync saib ob npaug ntawm cov ncej renders (thiab yog li ua ob npaug ntawm tus nqi refresh) kom lawv khiav hauv qhov hloov pauv hloov tshiab.

FreeSync nta
FreeSync muaj tus nqi kom zoo dua G-Sync vim nws siv cov qauv qhib tsim los ntawm VESA, Adaptive-Sync, uas kuj yog ib feem ntawm VESA's DisplayPort spec.
Ib qho DisplayPort interface version 1.2a lossis siab dua tuaj yeem txhawb kev hloov pauv hloov tshiab.Thaum lub chaw tsim khoom yuav xaiv tsis siv nws, kho vajtse twb muaj lawm, yog li ntawd, tsis muaj nqi ntau lawm rau tus tsim los siv FreeSync.FreeSync tuaj yeem ua haujlwm nrog HDMI 1.4.(Rau kev pab nkag siab qhov twg yog qhov zoo tshaj plaws rau kev ua si, saib peb DisplayPort vs. HDMI tsom xam.)

Vim tias nws qhov kev qhib, FreeSync kev siv nws txawv ntawm cov saib.Cov lus qhia nyiaj txiag feem ntau yuav tau txais FreeSync thiab 60 Hz lossis ntau dua refresh npaum li cas.Cov lus qhia qis tshaj plaws yuav tsis tau qhov muag plooj, thiab qhov qis dua ntawm Adaptive-Sync ntau yam yuav tsuas yog 48 Hz.Txawm li cas los xij, muaj FreeSync (nrog rau G-Sync) cov lus qhia uas ua haujlwm ntawm 30 Hz lossis, raws li AMD, txawm tias qis dua.

Tab sis FreeSync Adaptive-Sync ua haujlwm zoo li txhua tus saib G-Sync.Pricier FreeSync saib ntxiv qhov muag plooj txo qis thiab Low Framerate Compensation (LFC) kom sib tw zoo dua rau lawv cov G-Sync cov neeg sib tw.

Thiab, dua, koj tuaj yeem tau txais G-Sync khiav ntawm FreeSync saib yam tsis muaj Nvidia ntawv pov thawj, tab sis kev ua haujlwm yuav poob qis.
