RTX 4070 Super CPU Requirements
The RTX 4070 Super sits in the sweet spot for 1440p gaming. It’s powerful enough for high frame rates but doesn’t demand flagship CPUs. At 1440p, mid-range CPUs perform excellently with minimal bottleneck. At 1080p high-refresh, faster CPUs provide more benefit.
RTX 4070 Super Specifications
- CUDA Cores: 7,168
- VRAM: 12GB GDDR6X
- Memory Bus: 192-bit
- Base/Boost Clock: 1,980 MHz / 2,475 MHz
- TDP: 220W
- DLSS: DLSS 3 with Frame Generation
- Price: ~$600
Target Performance Levels
At 1440p, the RTX 4070 Super typically delivers:
- AAA games ultra settings: 70-100 FPS
- AAA games high settings: 90-130 FPS
- Esports titles: 200+ FPS
- With DLSS 3 Frame Gen: Effectively doubles perceived frame rates
At 1080p, frame rates increase by roughly 30-50%, which is where CPU bottlenecking becomes more relevant. The faster the GPU pushes frames, the harder the CPU works to keep up.
CPU Requirements by Resolution
4K gaming: Minimal CPU requirements. Even budget CPUs work fine because the GPU is always the bottleneck at 4K.
1440p gaming: Moderate CPU requirements. Mid-range CPUs like the Ryzen 5 7600X perform excellently with minimal bottleneck.
1080p high-refresh: Higher CPU requirements. For 240Hz+ competitive gaming, higher-end CPUs provide meaningful benefits.

Best Overall: Ryzen 5 7600X
AMD Ryzen 5 7600X
6 Cores | 12 Threads | 5.3 GHz Boost | 32MB L3 | 105W TDP
The perfect value pairing for the RTX 4070 Super. Delivers 95%+ of high-end CPU gaming performance at a fraction of the cost. Zero bottleneck at 1440p.
The Ryzen 5 7600X is our top recommendation at $178. It delivers outstanding gaming performance within 5-10% of CPUs costing twice as much. At 1440p—the RTX 4070 Super’s sweet spot—there’s zero bottleneck. The GPU is always the limiting factor.
The AM5 platform provides DDR5 memory support and PCIe 5.0. While the RTX 4070 Super doesn’t saturate PCIe 4.0, the platform headroom ensures longevity for future upgrades. DDR5-6000 memory runs optimally with Ryzen 7000, providing additional performance compared to DDR4 platforms.
The 5.3 GHz boost clock and Zen 4 architecture provide excellent single-threaded performance, which is what matters most for gaming. The 32MB L3 cache keeps frequently accessed game data on-chip, reducing memory latency for smoother frame delivery.
Why 7600X Over Higher-End CPUs?
Consider the math: the Ryzen 7 7800X3D costs $386—that’s $208 more than the 7600X. At 1440p with the RTX 4070 Super, that $208 buys you approximately 0-5% more gaming performance because both CPUs are GPU-limited. That money would provide much larger gains invested elsewhere: better monitor, faster storage, or saved for future upgrades.
The 7600X is the smart choice unless you’re specifically targeting 1080p competitive gaming at 240Hz+ or planning to upgrade to a significantly faster GPU within a year.
Ryzen 5 7600X + RTX 4070 Super Performance
| Game | 1080p Ultra | 1440p Ultra |
|---|---|---|
| Cyberpunk 2077 | 95 FPS | 70 FPS |
| Hogwarts Legacy | 110 FPS | 75 FPS |
| Call of Duty MW3 | 180 FPS | 140 FPS |
| Fortnite | 220 FPS | 165 FPS |
| Spider-Man Remastered | 115 FPS | 85 FPS |
Best Gaming Performance: Ryzen 7 7800X3D
AMD Ryzen 7 7800X3D
8 Cores | 16 Threads | 5.0 GHz Boost | 96MB L3 | 120W TDP
The fastest gaming CPU available. 3D V-Cache technology eliminates any CPU bottleneck. Choose for 1080p competitive gaming or maximum frame rates.
The Ryzen 7 7800X3D features AMD’s 3D V-Cache with 96MB of L3 cache, delivering the highest gaming frame rates of any consumer CPU. For RTX 4070 Super builds, it ensures zero CPU bottleneck at any resolution—particularly valuable for 1080p competitive gaming at 240Hz+.
The 7800X3D runs cool at 120W TDP, significantly lower than Intel alternatives. A mid-range tower cooler handles it easily. The massive cache keeps game data on-chip, reducing memory latency and delivering the smoothest possible frame times.
When to Choose 7800X3D Over 7600X
- 1080p competitive gaming: Targeting 240Hz+ in esports titles
- Future GPU upgrades: Planning to upgrade to RTX 5080+ tier within 1-2 years

- Long-term investment: Plan to keep the CPU for 5+ years
Alternative: Ryzen 9 9800X3D
AMD Ryzen 9 9800X3D
8 Cores | 16 Threads | 5.2 GHz Boost | 96MB L3 | 120W TDP
Latest generation X3D with improved clocks. 5-10% faster than 7800X3D. Worth considering if budget allows.
Best Intel Performance: i5-14600K
Intel Core i5-14600K
14 Cores (6P+8E) | 20 Threads | 5.3 GHz Boost | 24MB L3 | 125W TDP
Intel’s gaming sweet spot with excellent multi-threaded performance. Great for gaming plus streaming or content creation.
The i5-14600K is ideal for RTX 4070 Super builds needing both gaming and productivity. With 6 P-cores and 8 E-cores, it handles streaming, video editing, and multi-tasking while gaming excellently.
Gaming performance is within 5% of AMD’s X3D processors in most titles. The 5.3 GHz P-core boost provides excellent single-threaded performance, keeping up with demanding games without bottlenecking the RTX 4070 Super at any resolution.
The “K” suffix indicates an unlocked multiplier for overclocking. With proper cooling, the 14600K can reach 5.5 GHz+ all-core on P-cores. However, it does require more substantial cooling than the efficient 7600X—budget for a quality tower cooler or 240mm AIO.
Alternative: i5-14600KF
Intel Core i5-14600KF
14 Cores (6P+8E) | 20 Threads | 5.3 GHz Boost | No iGPU
Same performance without integrated graphics. Save ~$70 if you don’t need iGPU.
Best Intel Value: i5-14400F
Intel Core i5-14400F
10 Cores (6P+4E) | 16 Threads | 4.7 GHz Boost | 20MB L3 | 65W TDP
Solid gaming at a reasonable price. Handles the RTX 4070 Super well at 1440p. Low power consumption.
The i5-14400F offers good gaming at mid-range pricing. At 1440p, expect 0-3% bottleneck—imperceptible during gameplay. The 65W TDP makes cooling easy; even stock coolers work adequately.
At 1080p with high refresh rates, the bottleneck increases to 5-10% in CPU-demanding titles, which may matter for competitive esports players. However, for most gamers targeting 60-144Hz at 1440p, the i5-14400F is more than sufficient.
The i5-14400F works with both DDR4 and DDR5 motherboards, providing flexibility. DDR4 builds cost less overall, making this a good choice for budget-conscious gamers who still want modern Intel performance.
Best Budget: i5-12400F
Intel Core i5-12400F
6 Cores | 12 Threads | 4.4 GHz Boost | 18MB L3 | 65W TDP
Incredible value for budget builds. Handles the RTX 4070 Super well at 1440p. DDR4 support keeps platform costs low.
At $134, the i5-12400F is the cheapest way to build a capable RTX 4070 Super system. At 1440p, bottlenecking is minimal (0-5%). DDR4 motherboards and RAM cost substantially less than DDR5, potentially saving $100-150.
At 1080p high-refresh, expect 8-15% bottleneck. For competitive 1080p gaming at 240Hz+, invest in a faster CPU. However, at 1440p—where most RTX 4070 Super owners game—the i5-12400F delivers excellent value.
The platform advantages are significant: B660 DDR4 motherboards start around $100, and DDR4-3200 kits cost $40-50. A complete platform (CPU + motherboard + RAM) runs about $280-300 compared to $450+ for AM5 or DDR5 Intel builds.
The LGA 1700 platform provides an upgrade path to 13th and 14th gen Intel processors if you want more CPU power later without changing motherboards.
Best Productivity + Gaming: i7-14700K
Intel Core i7-14700K
20 Cores (8P+12E) | 28 Threads | 5.6 GHz Boost | 33MB L3 | 125W TDP
Excellent for gaming plus serious productivity. 20 cores handle streaming, video editing, and multi-tasking effortlessly.
The i7-14700K is for users needing both excellent gaming and serious productivity capability. Its 20 cores provide exceptional multi-threaded performance for streaming, video editing, and development work.
For pure gaming with the RTX 4070 Super, the 14700K is “overkill” at 1440p—the GPU is always the limiting factor. However, the extra cores allow gaming while running background applications, streaming software, or recording without frame drops. If you multitask heavily while gaming, the 14700K justifies its premium.
The main consideration is power consumption and cooling. The 14700K can draw 250W+ under full load, requiring a quality cooler (280mm+ AIO or high-end air cooler) and a robust power supply (750W+ recommended for this pairing).
Bottleneck Analysis
Understanding CPU bottlenecks helps you make smarter purchasing decisions. The RTX 4070 Super is powerful but not so demanding that it requires flagship CPUs.
