Do you even need a capture card for streaming?
From a single gaming PC, OBS, Streamlabs or similar software can grab the game window or display directly. In that one‑PC scenario, your GPU is already rendering frames; a hardware capture card would just re‑capture the same output via HDMI and add cost and complexity. So if you only play on PC and stream from the same machine, you probably don’t need a capture card.
Capture hardware becomes important when:
-
You play on a console (PS5, PS5 Pro, Xbox Series X/S, Switch/Switch 2) and stream via a PC. Game Capture 4K X and 4K S are made for this case.
-
You run a dual-PC setup or need to capture HDMI from other devices like handhelds, phones, or external players.
Cam Link 4K solves a different problem: it turns HDMI from a camera into a webcam signal, so it’s about video presence, not gameplay capture with lag‑free passthrough.
How do Game Capture 4K X and 4K S differ?
Game Capture 4K X is Elgato’s most powerful external USB capture card. It uses HDMI 2.1 in/out and USB 3.2 Gen2 Type‑C to capture and passthrough high frame‑rate, high‑resolution signals, including up to 2160p144 with HDR10 and VRR for smooth, “no‑compromise” console or PC gaming. Supported sources include PS5/Pro, Xbox Series X/S, Switch, PC and other unencrypted HDMI devices.
Game Capture 4K S is the more mainstream high‑performance option. It offers pixel‑perfect 4K60 HDR capture, near‑zero latency passthrough, and support for 1440p120 and 1080p240, along with HDR10 capture (up to 1080p60) and HDR10 passthrough up to 4K60. It works over USB‑C with Windows, Mac and iPad, targeting typical 4K60 HDR or competitive high‑frame HD setups.
In practical terms:
-
4K X:
-
Capture up to 4K144, 4K30 HDR, 1440p144, 1080p240 with HDR in some modes.
-
Passthrough up to 4K144 HDR with VRR, ideal for PS5 Pro / high‑refresh TVs/monitors.
-
-
4K S:
-
Capture up to 4K60, 1440p120, 1080p240, with HDR10 capture at 1080p60.
-
Passthrough up to 4K60 HDR with VRR, aimed at 4K60 TVs and common competitive refresh rates.
-
If your display tops out at 4K60 HDR, 4K S is a better value buy. If you already run—or plan to run—4K120/144 with VRR on a PS5 Pro or top‑end PC, 4K X matches that level.
What does Cam Link 4K do – and why isn’t it a console capture card?
Cam Link 4K is a compact USB HDMI capture stick designed to convert HDMI output from a camera or other unencrypted devices into a webcam‑compatible signal for your PC. It has HDMI input on one end and USB 3.0 on the other; any supported resolution from 480p60 up to 2160p30 or 1080p60 appears as a webcam source in your streaming or conferencing apps.
Key traits:
-
It is UVC‑compliant, so Windows, macOS and most video apps see it as a standard webcam with no drivers.
-
Supported resolutions include 720p60, 1080p60, 1080i, and 4K30 or 4K60 (MJPEG) depending on mode, making it ideal for DSLR/mirrorless facecams.
-
It has no HDMI passthrough, meaning you don’t get a separate zero‑lag HDMI output to your TV; it just ingests HDMI and sends it to USB.
You technically can use Cam Link 4K with consoles, but you’d lose the ergonomic “play on TV while capturing” setup and risk latency. It’s better to treat Cam Link purely as a camera upgrade and use Game Capture devices for gameplay.

Recommendation by setup: which device should you buy?
PC-only streamers: do you need a card at all?
If you play and stream from one PC, capturing directly via OBS/Game Capture is enough. A capture card only becomes useful if you build a dual‑PC streaming rig or want to pull HDMI from a second device. For “do i need a capture card for streaming,” the blunt answer is: PC-only → usually no, console → yes.
Console + PC streaming
Here’s where an Elgato Game Capture card is the right tool.
-
High-end 4K120/144 HDR TV/monitor, PS5 Pro / top-tier PC:
-
Pick Game Capture 4K X. It preserves your 4K high‑refresh HDR experience with VRR while capturing clean footage for Twitch/YouTube.
-
-
Standard 4K60 HDR TV/monitor or high‑frame HD setup (1440p120 / 1080p240):
-
Pick Game Capture 4K S. It covers 4K60 HDR gaming plus high‑refresh HD, with near‑zero latency and plug‑and‑play support on Windows, Mac and iPad.
-
In both cases, you’ll want decent HDMI cables between console, card and display; check your HDMI cable listing and push buyers to high‑bandwidth cables for 4K60+ HDR.
Camera / creator setups
If your main upgrade is your face cam or talking‑head video, Cam Link 4K is the better purchase than a Game Capture card.
-
Pick Cam Link 4K if you’re using a DSLR/mirrorless/camcorder and want it seen as a webcam in OBS or conferencing apps, with up to 4K30 or 1080p60 feed quality.
-
Combine Cam Link 4K + Game Capture 4K S or 4K X only if you want both high‑end gameplay capture and high‑end camera input.
FAQ
Q: Do I need a capture card to stream from a PC?
You usually do not need a capture card to stream from a single gaming PC. Streaming software can capture the game or display directly, using your GPU’s rendered frames without looping HDMI out and back in through hardware.
Capture cards become necessary when you add a second PC (dual‑PC streaming) or external HDMI sources like consoles, handhelds or cameras. In those cases, Game Capture 4K X or 4K S handle console/PC gameplay, while Cam Link 4K handles camera feeds.
Q: What's the difference between Elgato Cam Link and Game Capture?
Elgato Cam Link 4K is a compact HDMI‑to‑USB stick that makes cameras appear as webcams. It has HDMI input and a USB 3.0 output that your PC sees via UVC, supporting resolutions like 1080p60 and 4K30, and is widely compatible with conferencing and streaming apps.
Game Capture devices (4K X and 4K S) are full capture cards with HDMI input, HDMI passthrough to your TV/monitor and USB‑C output to your PC. They’re built for console/PC gameplay, supporting higher refresh rates, HDR and VRR, and integrate with capture utilities for recording and streaming. In simple terms: Cam Link is for camera → PC, Game Capture is for console/PC → display + PC.
Q: Can I use Game Capture 4K X with a PS5 or Xbox?
Yes, Game Capture 4K X is explicitly designed to work with PS5/PS5 Pro and Xbox Series X/S. Official specs list these consoles as supported sources, and the HDMI 2.1 input/output plus up to 4K144 HDR passthrough and VRR make it ideal for capturing next‑gen gameplay without sacrificing your TV or monitor experience.
Game Capture 4K S also supports PS5 and Xbox Series X/S for 4K60 HDR, 1440p120 and 1080p240 capture and passthrough, targeted at more typical Indian living room and competitive setups. In both cases, match the card to your display’s capability: 4K X for 4K120/144 HDR, 4K S for 4K60 HDR and high‑frame HD.
