title="Insteekkaart">insteekkaarten</a> voor <a href="/wiki/Computer" title="Computer">computers</a> (slots). De PCIe-standaard ondersteunt insteekkaarten van maximaal 300 watt, waarvan 75 watt uit het PCIe-slot. Bij een PCIe-slot hoort ook een PCIe-bus. Aan de uiteinden van de PCIe-bussen bevinden zich de PCIe-slots, die bestemd zijn voor insteekkaarten (<a href="/wiki/PCI-kaart" class="mw-redirect" title="PCI-kaart">PCI-kaart</a>). Het vormt een oplossing voor de steeds grotere vraag naar snelheid. PCI Express vervangt twee vorige insteekkaartstandaarden: <a href="/wiki/Peripheral_Component_Interconnect" title="Peripheral Component Interconnect">PCI</a> en <a href="/wiki/Accelerated_Graphics_Port" title="Accelerated Graphics Port">AGP</a>. </p><p>Een conventionele PCI-kaart past niet in een PCI Express-slot, zoals ook blijkt uit de afbeelding. </p><p>Oudere bustypen zijn: </p> <ul><li><i>PCI</i>: een tragere voorganger van de PCI-Express; wordt nog steeds veel gebruikt voor insteekkaarten die minder snelheid nodig hebben (bijvoorbeeld netwerkkaarten).</li> <li><i>VLB</i>: <a href="/wiki/VESA_Local_Bus" title="VESA Local Bus">VESA Local Bus</a> een snellere bus dan EISA voor videokaarten die door PCI overbodig werd.</li> <li><i>EISA/ISA</i>: <a href="/wiki/Industry_Standard_Architecture" title="Industry Standard Architecture">Industry Standard Architecture</a>, is een verouderde bus voor uitbreidingskaarten. De 'E' in EISA staat voor 'Extended'. Maar ook de Extended-versie van de ISA is alweer verouderd.</li></ul> <p>Het oude PCI bood een snelheid van 133 MB/s (die gedeeld is onder alle gebruikte PCI-slots), en de speciale AGP-kaart voor grafisch gebruik in zijn snelste x8-variant 2,1 GB/s. PCI-Express-slots komen in een aantal varianten, de x1 met één enkel <a href="/wiki/Serieel_(informatica)" class="mw-redirect" title="Serieel (informatica)">serieel kanaal</a> haalt een snelheid van 250 MB/s en de x16-variant met 16 kanalen haalt 4 GB/s. Daar tussen liggen de x2 x4 en x8 varianten. </p><p>Alhoewel niet alle <a href="/wiki/Bandbreedte" title="Bandbreedte">bandbreedte</a> van PCI-E x16 gebruikt wordt in de huidige generatie <a href="/wiki/Videokaart" title="Videokaart">videokaarten</a>, biedt x16 wel voordelen bij het gebruik van <a href="/wiki/SLI" class="mw-redirect" title="SLI">SLI</a> of <a href="/wiki/ATI_CrossFire" class="mw-redirect" title="ATI CrossFire">Crossfire</a>, omdat beide videokaarten dan 2 (of 4) GB/s tot hun beschikking hebben, wat nog steeds twee keer zo snel is als AGP x8. De oudere variant van PCI-E x16 is PCI-E x8. Dit betekent echter niet dat videokaarten in deze sleuf maar de helft presteren van PCI-E x16. </p><p>PCI Express-kaarten zijn er in een aantal fysieke formaten, waaronder een kleiner 'Low profile'-formaat. </p><p>Al geruime tijd voordat PCI Express werd ontwikkeld bestond er al <a href="/wiki/PCI-X" title="PCI-X">PCI-X</a>, de afkorting hiervan mag echter niet worden verward met PCI Express. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="PCI_Express_2.0">PCI Express 2.0</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=PCI_Express&veaction=edit&section=1" title="Bewerk dit kopje: PCI Express 2.0" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=PCI_Express&action=edit&section=1" title="De broncode bewerken van de sectie: PCI Express 2.0"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In 2008 werd PCI Express 2.0 geïntroduceerd. De 2.0-versie heeft enkele voordelen tegenover zijn voorganger. PCI Express 2.0 heeft een bandbreedte van 500 megabytes per seconde per pin, een verdubbeling van de oorspronkelijke snelheid. Ook is er een versie uitgebracht die meer energie kan leveren aan (grafische) kaarten die veel stroom verbruiken. Een andere vernieuwing is Input-Output Virtualization (IOV), waardoor meerdere <a href="/wiki/Virtuele_machine" title="Virtuele machine">virtuele machines</a> gemakkelijker hardware, zoals netwerkkaarten, kunnen delen. Als laatste is het mogelijk om met kabels van maximaal 10 meter externe apparatuur aan de PCI Express-bus te koppelen. Dit kan handig zijn om bijvoorbeeld een laptop een krachtige GPU te geven wanneer hij gebruikt wordt ter vervanging van een volwaardige desktopcomputer. </p><p>PCI Express 2.0 is volledig <a href="/wiki/Achterwaartse_compatibiliteit" title="Achterwaartse compatibiliteit">achterwaarts compatibel</a> met de PCI Express 1.x-standaard, dus PCI-E 2.0-kaarten werken ook met PCI-E 1.0/1.1, alleen dan wel met de maximale snelheid van het PCI-E 1.x-slot. </p> <div class="mw-heading mw-heading2"><h2 id="PCI_Express_3.0">PCI Express 3.0</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=PCI_Express&veaction=edit&section=2" title="Bewerk dit kopje: PCI Express 3.0" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=PCI_Express&action=edit&section=2" title="De broncode bewerken van de sectie: PCI Express 3.0"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>PCI Express 3.0 Base-specificatie revisie 3.0 werd beschikbaar gesteld in november 2010, na meerdere vertragingen. In augustus 2007 kondigde PCI-SIG aan dat PCI Express 3.0 een bitsnelheid van 8 gigatransfers per seconde (GT/s) zou dragen en dat het compatibel zou zijn met bestaande PCIe-implementaties. Op dat moment werd ook aangekondigd dat de uiteindelijke specificaties voor PCI Express 3.0 zou worden uitgesteld tot 2011. Nieuwe functies voor de PCIe 3.0-specificatie zijn een aantal optimalisaties voor verbeterde signalering en integriteit van de gegevens, inclusief zender- en ontvangeregalisatie, PLL-verbeteringen, klok/datarecovery, en kanaaluitbreidingen voor momenteel<sup class="noprint nopopups"><a href="/wiki/Wikipedia:Tijdsaanduiding" title="Wikipedia:Tijdsaanduiding"><span title="Voor deze uitspraak is sinds 26 maart 2019 een preciezere tijdsaanduiding gewenst.">[(sinds) wanneer?]</span></a></sup> ondersteunde topologieën. </p><p>Na een zes maanden durende technische analyse van de schalen van de PCIe interconnectbandbreedte bleek bij analyse van PCI-SIG dat 8 gigatransfers per seconde te kunnen worden bereikt in mainstream silicium procestechnologie en zou kunnen worden ingezet bij bestaande goedkope materialen en infrastructuur met behoud van volledige compatibiliteit aan de PCIe-protocolstack. </p><p>PCIe 3.0 verbetert de coderingstechniek van de vorige 8b/10b naar 128b/130b, waardoor de overhead vermindert tot ongeveer 1,54% ((130-128) / 130), tegenover de 20% van PCIe 2.0. Dit wordt bereikt door een techniek genaamd "versluiering" (scrambling) dat een bekende binaire polynoom toepast aan een datastroom in een feedbacktopologie. Doordat de versluieringpolynoom bekend is, kunnen de gegevens worden hersteld door het uitvoeren van een feedbacktopologie met behulp van de inverse polynoom. De bitrate van 8 GT/s van PCIe 3.0 levert effectief 985 MB/s per lane, dubbele PCIe 2.0 bandbreedte. PCI-SIG verwacht dat de PCIe 3.0-specificaties een strenge technische doorlichting en validatie ondergaan voordat ze worden vrijgegeven aan de industrie. Deze werkwijze, die werd gevolgd bij de ontwikkeling van eerdere generaties van de PCIe-basis, en diverse vormfactorspecificaties omvat de bevestiging van de uiteindelijke elektrische parameters met gegevens van testen van silicium en andere simulaties uitgevoerd door meerdere leden van de PCI-SIG. </p><p>AMD's toenmalige grafische vlaggenschip, de Radeon HD 7970, gelanceerd op 9 januari 2012, was 's werelds eerste grafische kaart met PCIe 3.0. Eerste reviews suggereerden dat de nieuwe interface niet zou verbeteren t.o.v. de grafische prestaties van PCIe 2.0. Echter zou de nieuwe interface voordeliger blijken wanneer deze gebruikt wordt voor algemene doeleinden in het computergebruik met technologieën zoals OpenCL, CUDA en C++ AMP. </p> <div class="mw-heading mw-heading2"><h2 id="PCI_Express_3.1">PCI Express 3.1</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=PCI_Express&veaction=edit&section=3" title="Bewerk dit kopje: PCI Express 3.1" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=PCI_Express&action=edit&section=3" title="De broncode bewerken van de sectie: PCI Express 3.1"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In september 2013 werd aangekondigd dat de PCI Express 3.1-specificatie eind 2013 of begin 2014 zou worden uitgebracht, waarbij verschillende verbeteringen van de gepubliceerde PCI Express 3.0-specificatie op drie gebieden werden geconsolideerd: <a href="/wiki/Energiebeheer" title="Energiebeheer">energiebeheer</a>, prestaties en functionaliteit.

PCI Express 4.0-specificaties levert ook OCuLink-2 op, een alternatief voor de Thunderbolt-connector. OCuLink versie 2 heeft tot 16 GT/s (8 GB / s totaal voor × 4 rijstroken), terwijl de maximale bandbreedte van een Thunderbolt 3-connector 5 GB / s is.
