The Best CPUs for the RTX 4070 Ti and 4070 Ti Super
Six processors for an RTX 4070 Ti or 4070 Ti Super, compared on cache, cores and platform.
By The PC Journal editorial team
12 min read6 products evaluated
The RTX 4070 Ti has 12GB of memory and the 4070 Ti Super 16GB, but both need the same kind of processor: six to eight fast cores with a large cache. This guide covers both.
We compared six processors on cache, cores, rated power and platform, using AMD and Intel specifications. We did not benchmark them.

Best Match for an RTX 4070 Ti1 of 6
AMD Ryzen 7 7800X3D on Amazon (opens in a new tab)
The Ryzen 7 7800X3D was the first eight-core AM5 chip with 3D V-Cache.
Best for
- High-refresh 1440p builds.
Skip if
- Skip it if this is a deal-breaker for 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. Its 5GHz boost clock ranks fifth of 6 here, behind the Core Ultra 7 265KF (5.5GHz) and ahead of the Ryzen 5 7600X3D (4.7GHz). On core count it ties with the Ryzen 7 9800X3D and the Ryzen 7 9700X at 8 cores.
You also get 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. It was priced above the Ryzen 7 9700X and below the Ryzen 7 9800X3D at the time of writing.
Key dimensions & specs
- L3 cache: 96MB
- Max boost: 5GHz
- Cores / threads: 8 cores
- Rated power: 120W
- Threads: 16
- Socket: AM5
- Memory: DDR5
- Cooler in box: No
- Integrated graphics: Yes
Pros
- 96MB of L3 cache from 3D V-Cache
- Integrated graphics for display output without a graphics card
- First-generation AM5 3D V-Cache
- The Zen 4 architecture
Cons
- No cooler in the box
- Costs more than the Ryzen 5 7600X3D at the time of writing
Best Zen 5 X3D2 of 6
AMD Ryzen 7 9800X3D on Amazon (opens in a new tab)
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
- Worth skipping when no cooler in the bo is a problem.
Why we like it
AMD moved the cache below the cores on this generation, which lets it clock higher than the 7800X3D. On boost clock it sits mid-pack at 5.2GHz: the Core Ultra 7 265KF offers 5.5GHz, and the Ryzen 5 7600X3D comes in at 4.7GHz. It matches the Ryzen 7 7800X3D and the Ryzen 7 9700X on core count (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. It was the highest-priced of the 6 picks at the time of writing, so the case for it rests on what it adds over the Ryzen 7 7800X3D and the rest.

Cons
- No cooler in the box
- Costs more than the Ryzen 5 7600X3D at the time of writing
Best Budget X3D3 of 6
AMD Ryzen 5 7600X3D on Amazon (opens in a new tab)
The Ryzen 5 7600X3D brings 96MB of L3 cache to a six-core AM5 chip at a 65W rating.
Best for
- Spending more on the card.
Skip if
- Choose another pick if you can't accept this: 6 cores leave less headroom for streaming alongside games.
Why we like it
It is the cheapest way into AMD's cache-heavy gaming line on AM5. It matches the Ryzen 7 7800X3D and the Ryzen 7 9800X3D on L3 cache (96MB). Its 4.7GHz boost clock is the lowest in this group; the Core Ultra 7 265KF leads at 5.5GHz.
On core count it trails the group at 6 cores, while the Core Ultra 7 265KF offers 20 cores. On rated power it ties with the Ryzen 7 9700X at 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 cost the least of the 6 picks at the time of writing, with the Core i5-14600K the next step up.

Best LGA1700 Pairing4 of 6
Intel Core i5-14600K on Amazon (opens in a new tab)
The Core i5-14600K is an unlocked fourteen-core LGA1700 chip.
Best for
- Intel builds on Z790 or B760.
Skip if
- Look at the others if this bothers you: no cooler in the box.
Why we like it
It works with DDR4 or DDR5 boards, which keeps older memory useful. It boosts to 5.3GHz, and the unlocked multiplier allows overclocking on a Z-series board. On L3 cache it trails the group at 24MB, while the Ryzen 7 7800X3D offers 96MB.
On boost clock it sits mid-pack at 5.3GHz: the Core Ultra 7 265KF offers 5.5GHz, and the Ryzen 5 7600X3D comes in at 4.7GHz. Its 14 cores core count ranks second of 6 here, behind the Core Ultra 7 265KF (20 cores) and ahead of the Ryzen 5 7600X3D (6 cores). It matches the Core Ultra 7 265KF on rated power (125W).
An LGA1700 socket is unique to it among these picks, while the Core Ultra 7 265KF uses an LGA1851 socket. On price it sat second of 6, between the cheaper Ryzen 5 7600X3D and the pricier Core Ultra 7 265KF, at the time of writing.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Game-relevant specs
- We compared L3 cache, boost clocks and core counts from AMD's and Intel's product pages.
- Power and cooling
- We recorded each chip's rated power and what cooler class it needs.
- Platform cost
- We noted socket, memory type and whether a cooler is included, since they change the real price.
- Upgrade path
- We considered how long each socket is likely to receive new CPUs.
What to Look for in a CPUs for RTX 4070 Ti
Key buying criteria so you get the right fit the first time.
Match the CPU to your graphics card and monitor
At 1440p and 4K the graphics card sets most frame rates, so a mid-range CPU is often enough. At 1080p with a high-refresh monitor, the CPU matters much more.
Spend on the part that limits your games, not on the bigger number.
Cache helps games more than clocks
AMD's X3D chips add a large stacked L3 cache that keeps more game data close to the cores. In CPU-limited games that often helps more than a higher boost clock.
The gain shrinks when the graphics card is the limit.
Check BIOS support before buying
Newer CPUs on older boards may need a BIOS update before the system will start. Check the board's CPU support list for the version you need and whether the board can flash without a CPU installed.
Budget for the cooler
Most unlocked chips ship without a cooler. A 65W part runs well on a basic single tower, while 120W to 170W parts need a dual tower or an AIO to hold their boost clocks.
Add the cooler to the CPU price when comparing.
The socket decides your upgrade path
The socket fixes which motherboards and future CPUs you can use. AM5 has had several CPU generations; AM4 has no newer chips coming.
If you plan to upgrade later, a current platform is worth a small premium.
Cores matter for streaming and creation
Six and eight cores cover gaming. Streaming with CPU encoding, video editing and compiling benefit from twelve or sixteen.
If you encode on the graphics card instead, core count matters less.

Frequently Asked Questions
Is AM4 still worth buying into?
For an upgrade to an existing AM4 system, yes. For a new build, AM5 or LGA1851 gives a longer upgrade path.
Do I need to buy a separate cooler?
Usually yes. Only some chips, such as the Ryzen 5 7600 and 5600X, include a basic cooler; unlocked high-end models do not.
What memory should I pair with it?
AM5 and LGA1851 use DDR5; AM4 uses DDR4. For AM5, a 32GB DDR5-6000 kit is a common pairing; check the board's memory support list.
What does X3D mean on a Ryzen CPU?
It marks AMD's 3D V-Cache chips, which stack extra L3 cache on the processor. Games that are limited by the CPU tend to run faster on them.
Will a new CPU work in my current motherboard?
Only if the socket matches and the board's BIOS supports it. Check the maker's CPU support list for the minimum BIOS version.
Should I choose Intel or AMD for gaming?
At the high end, AMD's X3D chips lead in many CPU-limited games. Intel's Core Ultra chips offer more cores for work at similar prices. Choose by workload and platform cost.
Bottom Line
The Ryzen 7 7800X3D is the best partner for either card. The 9800X3D adds headroom, the 7600X3D saves money, and the i5-14600K or Core Ultra 7 265KF cover Intel builds.
