Streaming while you game is one of the most demanding things you can ask a PC to do. The CPU has to render the game, encode the broadcast, and juggle chat overlays and alerts all at once, so core count and multithreaded muscle matter far more than in a gaming-only build. The right processor keeps both your frame rate and your stream smooth.
Our picks lean on high-core AMD chips like the 12-core $315 Ryzen 9 7900X, with budget and prebuilt alternatives for different wallets. Below is how to choose a streaming CPU, then five options that will not drop frames when the encoder kicks in.

How to Choose
- Core and thread count: Aim for at least 8 cores and 16 threads; 12-core chips like the Ryzen 9 7900X leave headroom for x264 software encoding alongside gaming.
- Encoding strategy: If you offload encoding to your GPU’s NVENC, a slightly lower core count is fine; for CPU-based x264, more cores directly improve stream quality.
- Platform longevity: AM5 chips like the 7900X sit on a socket with a long upgrade path, protecting your investment.
- Cooling headroom: High-core chips run hot under a dual workload, so budget for a strong air or 360mm liquid cooler.
- Budget balance: Do not starve your GPU to buy the biggest CPU; a $315 12-core chip plus a solid GPU beats an overkill CPU with a weak card.
The Best Picks Reviewed
AMD Ryzen 9 7900X
At $315 the 12-core, 24-thread Ryzen 9 7900X is our top streaming pick. Those extra cores absorb x264 encoding without stealing frames from your game, and the modern AM5 platform gives you room to upgrade later. It is the best balance of price and multithreaded power here.
AMD Ryzen 9 5900X
The $449.99 Ryzen 9 5900X brings the same 12-core, 24-thread layout to the mature AM4 platform. If you already own an AM4 board, it is a drop-in streaming upgrade that avoids the cost of new RAM and a motherboard.
Intel Core i5-12400
For $194.99 the 6-core i5-12400 is the budget entry, and paired with GPU NVENC encoding it streams 1080p smoothly. It is the value choice for new streamers who lean on their graphics card for the heavy lifting.
STORMCRAFT Falcon Prebuilt (Ryzen 7 7800X3D)
The $2,049.99 STORMCRAFT Falcon pairs a Ryzen 7 7800X3D with an RTX 5070, 32GB DDR5, and a 1TB SSD. The 7800X3D games superbly and, with NVENC handling the stream, it is a turnkey streaming rig with no assembly required.
AMD Ryzen 9 5900X (OEM)
At $529 the OEM-pack 5900X is the same 12-core silicon for builders who already have a cooler. It is worth watching when tray pricing dips below the boxed version.
Frequently Asked Questions
How many cores do I need to stream and game?
Eight cores is a comfortable minimum, but 12-core chips like the Ryzen 9 7900X give real headroom for CPU encoding while keeping your game smooth.
Should I use NVENC or x264 encoding?
Modern NVENC on recent NVIDIA GPUs looks excellent and frees your CPU, so most streamers use it. Reserve x264 for when you want maximum quality and own a high-core CPU.
Is the Ryzen 7800X3D good for streaming?
Yes, especially paired with NVENC. Its gaming performance is elite, and offloading the encode to the GPU means its 8 cores are plenty, as in the STORMCRAFT prebuilt.
Do I need liquid cooling?
Not strictly, but a dual workload runs hot. A strong dual-tower air cooler or a 360mm AIO keeps a 12-core chip from throttling during long streams.
Final Thoughts
For most streamers the AMD Ryzen 9 7900X hits the sweet spot: 12 cores for smooth simultaneous encoding, a fair $315 price, and a future-proof AM5 socket. Budget builders can lean on the i5-12400 with NVENC, while the STORMCRAFT Falcon offers a plug-and-play path. Match your CPU choice to your encoding method and keep it well cooled.
