The Best CPUs for the RTX 5070 Ti
Six processors for an RTX 5070 Ti at 1440p, compared on cache, cores, power draw and platform.
By Alex Morgan, PC Hardware Editor
12 min read6 products evaluated
The RTX 5070 Ti handles 1440p at high refresh rates and many games at 4K. At 1440p the CPU still matters, so a chip with plenty of L3 cache keeps frame times steady.
We compared six processors on cache, cores, rated power and platform, using AMD and Intel specifications. We have not tested them ourselves.

Our Picks
Best Match for an RTX 5070 Ti1 of 6
AMD Ryzen 7 7800X3D
The Ryzen 7 7800X3D was the first eight-core AM5 chip with 3D V-Cache.
Best for
- High-refresh 1440p builds.
Skip if
- Look at the others if this bothers you: no cooler in the box.
Why we like it
It carries the same 96MB of L3 as the 9800X3D at a lower boost clock and a lower price. On boost clock it sits mid-pack at 5GHz: the Core i7-14700KF offers 5.6GHz, and the Ryzen 5 7600X3D comes in at 4.7GHz. It matches the Ryzen 7 9800X3D and the Ryzen 7 9700X on core count (8 cores).
It also comes with the Zen 4 architecture. 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. Its price falls between the Ryzen 7 9700X and the Ryzen 7 9800X3D, based on our last check.

AMD Ryzen 7 9800X3D
The Ryzen 7 9800X3D pairs 96MB of L3 cache with eight Zen 5 cores.
Best for
- Builds that may take a faster card later.
Skip if
- Skip it if this is a deal-breaker for you: no cooler in the box.
Why we like it
AMD moved the cache below the cores on this generation, which lets it clock higher than the 7800X3D. Its 5.2GHz boost clock ranks fourth of 6 here, behind the Core i7-14700KF (5.6GHz) and ahead of the Ryzen 5 7600X3D (4.7GHz). On core count it ties with the Ryzen 7 7800X3D and the Ryzen 7 9700X at 8 cores.
It also comes with an unlocked multiplier, a first for AMD's X3D chips. 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. At our last price check it topped the group, with the Ryzen 7 7800X3D the nearest cheaper option.

Best for
- Putting more money into the card.
Skip if
- Worth skipping when 6 cores leave less headroom for streaming alongside games is a problem.
Why we like it
It is the cheapest way into AMD's cache-heavy gaming line on AM5. On L3 cache it ties with the Ryzen 7 7800X3D and the Ryzen 7 9800X3D at 96MB. On boost clock it trails the group at 4.7GHz, while the Core i7-14700KF offers 5.6GHz.
Its 6 cores core count is the lowest in this group; the Core Ultra 7 265KF leads at 20 cores. It matches the Ryzen 7 9700X on rated power (65W). 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.
No cooler is included; a single-tower air cooler is enough at its rating. It was the cheapest of the group when we checked; the Core i7-14700KF was the next step up.
