Streaming from the same PC you play on adds an encoding job on top of the game. Modern graphics cards encode with little impact, so extra cores matter most if you encode on the CPU, record in high quality or run many apps at once.

We compared six CPUs with 12 or more cores on threads, cache, power and platform. This is a research-based comparison built from maker specifications; we did not test these parts ourselves.

Our Picks

Largest Game Cache1 of 6

AMD Ryzen 9 9950X3D

The Ryzen 9 9950X3D is the one chip here that leads in both halves of the job: 16 cores for encoding and 3D V-Cache for games.

Best for

Players chasing 1% lows in simulation and esports titles.

Skip if

Look at the others if this bothers you: 170W rating calls for a large air cooler or a 280mm-plus AIO.
AMD Ryzen 9 9950X3D

Why we like it

It suits streamers who refuse to trade frame rates for stream quality. Nothing else here matches its 128MB L3 cache; the Ryzen 9 9950X comes closest at 64MB. It matches the Ryzen 9 9950X on boost clock (5.7GHz).

On rated power it ties with the Ryzen 9 9950X and the Ryzen 9 7900X at 170W. It also offers 3D V-Cache on one of its two core dies and a design aimed at both games and content creation. It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; a 600-series board may need a BIOS update first, so check the maker's CPU support list for the minimum version.

Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. Only the Ryzen 9 9950X came close to it on price at the time of writing; it cost the most of the 6 picks.

Pass on it if 170W rating calls for a large air cooler or a 280mm-plus AIO rules it out for your setup.
AMD Ryzen 9 9950X

Why we like it

It is the better buy when CPU encoding and editing matter more than the last few frames per second. It matches the Ryzen 9 9900X and the Ryzen 9 7900X on L3 cache (64MB). It matches the Ryzen 9 9950X3D on boost clock (5.7GHz).

On rated power it ties with the Ryzen 9 9950X3D and the Ryzen 9 7900X at 170W. It also comes with AMD's recommendation of a liquid cooler. It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; a 600-series board may need a BIOS update first, so check the maker's CPU support list for the minimum version.

Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. It was priced above the Core i7-14700K and below the Ryzen 9 9950X3D at the time of writing.

The Ryzen 9 9900X steps down to 12 cores on Zen 5.

Best for

Buyers who want 64mb of l3 cache.

Skip if

Skip it if this is a deal-breaker for you: no cooler in the box.
AMD Ryzen 9 9900X

Why we like it

It leaves plenty of threads for an encoder alongside a game, with a lower power rating than the 16-core chips. It matches the Ryzen 9 9950X and the Ryzen 9 7900X on L3 cache (64MB). It matches the Ryzen 9 7900X and the Core i7-14700K on boost clock (5.6GHz).

On core count it ties with the Ryzen 9 7900X at 12 cores. On rated power it leads this guide at 120W, ahead of the Core Ultra 7 265K (125W). It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; a 600-series board may need a BIOS update first, so check the maker's CPU support list for the minimum version.

Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. When we checked, only the Core Ultra 7 265K and cheaper picks cost less, and the Core i7-14700K cost more.

Best Value 12-Core4 of 6

AMD Ryzen 9 7900X

The Ryzen 9 7900X has 12 Zen 4 cores on AM5.

Best for

Streamers on a budget who want many cores.

Skip if

Pass on it if 170W rating calls for a large air cooler or a 280mm-plus AIO rules it out for your setup.
AMD Ryzen 9 7900X

Why we like it

It is a cheaper way to the same thread count as the 9900X, at a higher power rating. It matches the Ryzen 9 9950X and the Ryzen 9 9900X on L3 cache (64MB). It matches the Ryzen 9 9900X and the Core i7-14700K on boost clock (5.6GHz).

On core count it ties with the Ryzen 9 9900X at 12 cores. It also offers the Zen 4 architecture, a 5nm process and PCIe 5.0 support on AM5. It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; check the board's CPU support list for the minimum BIOS version.

Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. No other pick here cost less at our last price check, and the Core Ultra 7 265K was closest.

Well-Rounded Choice5 of 6

Intel Core Ultra 7 265K

The Core Ultra 7 265K has 20 cores and an integrated GPU with Quick Sync, which can take on encoding or recording work.

Best for

Buyers who want 5.5ghz maximum boost.

Intel Core Ultra 7 265K

Why we like it

It fits streamers who prefer Intel's platform. On L3 cache it trails the group at 30MB, while the Ryzen 9 9950X3D offers 128MB. On boost clock it trails the group at 5.5GHz, while the Ryzen 9 9950X3D offers 5.7GHz.

It matches the Core i7-14700K on rated power (125W). You get an LGA1851 socket here, which sets it apart from the Ryzen 9 7900X and its an AM5 socket. It also comes with 8 performance and 12 efficient cores and a built-in NPU for AI features.

It needs an LGA1851 board (Intel 800-series chipset) and DDR5 memory; LGA1700 boards and coolers without an LGA1851 mounting kit will not fit. Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. Its price falls between the Ryzen 9 7900X and the Ryzen 9 9900X, based on our last check.
