Best CPU for ASUS ROG STRIX Z790-E GAMING WIFI II Motherboard

The ASUS ROG STRIX Z790-E GAMING WIFI II is a high-end motherboard designed for Intel’s latest 12th, 13th and 14th generation Core processors. With robust power delivery, advanced cooling, and plenty of connectivity, this motherboard can handle the most powerful consumer CPUs on the market. But which CPU is the best fit for this board? We have tested and reviewed latest CPUs, and below are top recommended ones for ROG STRIX Z790-E GAMING WIFI II Motherboard:

Intel Core i9-14900K

The Core i9-14900K sits atop Intel’s consumer CPU lineup based on the new Raptor Lake architecture. It comes with 24 cores and 32 threads, with P-cores boosting up to a blistering 6.0 GHz. With high clocks and high core counts, the 14900K promises record-setting performance but also high power draw and heat output.

The Z790-E GAMING WIFI II can easily keep up with the 14900K thanks to its beefy 18+1+2 power stages. There’s also plenty of cooling between the large VRM heatsink, chipset fan and multiple fan headers for case fans. You can expect excellent multi-threaded performance in rendering, video editing, code compiling and other productivity workloads. Gaming frame rates will also reach new heights.

The only downsides are the high price tag and power consumption, but for pure performance the 14900K is hard to beat as the best CPU for this motherboard.

Intel Core i7-14700K

If the 14900K is out of your budget, the Core i7-14700K makes for an excellent alternative with nearly identical gaming performance. It dials the core count down to 20 cores and 28 threads but retains the same 5.6GHz max P-Core Turbo frequency.

With fewer cores, the 14700K pulls over 100W less power under full load compared to the 13900K. Heat output is also reduced. But it’s still no slouch, outperforming the 12900K in most games and many productivity benchmarks too. It represents a great balance of performance, power and cost.

The Z790-E GAMING WIFI II can easily handle the power requirements of the 14700K without breaking a sweat. You still get support for fast DDR5 memory, PCIe 5.0 graphics cards and speedy storage. At around $400, the 14700K could be considered the sweet spot CPU for this motherboard.

Intel Core i9-13900K

The 13900K dominated the consumer CPU space previously on Intel’s 13th gen Raptor Lake architecture. With 24 cores, 32 threads and a 5.8GHz peak P-Core clock, it has extremely strong multi-threaded performance. While the new 14th-gen parts edge it out slightly, the 13900K is still a performance monster.

Since it’s one generation older, the 13900K has lower base power consumption, TDP rating and thermals compared to the 14900K. This makes it a little easier to cool while gaming or overclocking on the Z790-E board. Performance is within striking distance of the 14900K in most real-world gaming, streaming and editing workflows.

If you already own a good Z790 motherboard like the ASUS Z790-E, using a 13900K makes more financial sense than upgrading to 14th-gen. You still get leading frame rates, blistering fast rendering and excellent gaming live streaming capabilities. At current street prices under $550, it hits a nice balance between price and no-compromise performance.

Intel Core i7-13700K

Intel’s Core i7-13700K delivers nearly as impressive a punch as the 13900K in many games and applications. For $100+ less, the 13700K dials the core count down to 16 cores and 24 threads. Clock speeds remain very quick, with the P-Cores Turbo Boost max hitting 5.8 GHz just like the 13900K.

With fewer cores, the 13700K pulls over 100 fewer watts of power compared to the 13900K. This gives more thermal and overclocking headroom on the Z790-E motherboard. DDR5 memory speeds, PCIe lanes and other functionality remain consistent with the more expensive 13900K.

If playing games at 1440p or 4K resolution, the 13700K performs within a few percentage points of the 13900K in most titles while costing considerably less. Productivity software like video editors, 3D modeling tools and compilers see a bigger performance hit from losing those 8 E-cores. But the 13700K remains very capable as an all-rounder CPU perfect for this motherboard.

Intel Core i5-14600K

The Intel Core i5-14600K brings exceptional performance and value to the high-end ASUS ROG STRIX Z790-E GAMING WIFI II motherboard. With its 14 core (6P + 8E) design based on Intel’s latest architecture, this CPU can power through demanding games, creative workloads, and intense multitasking.

While it trails the flagship i9 models slightly in all-out speed, the i5-14600K delivers excellent 1080p and 1440p gaming frame rates well over 100fps in most titles. Its hybrid architecture ensures background tasks don’t hamper main gaming or app performance thanks to Intel Thread Director. This motherboard also allows you to overclock the P-cores to around 5.1 GHz to push performance further on this efficient 14nm CPU.

With support for fast DDR5-5600 memory, PCIe 5.0 graphics cards and storage, and advanced connectivity like WiFi 7, the Z790-E GAMING WIFI II motherboard pairs perfectly with the i5-14600K to create a high-end gaming rig or prosumer creative workstation at a reasonable price. Just make sure to factor in a good aftermarket cooler since Intel doesn’t include one. Overall, the Core i5-14600K hits a sweet spot of price and performance to fully leverage this premium motherboard’s capabilities.

Conclusion

The ASUS ROG STRIX Z790-E GAMING WIFI II motherboard delivers top-tier performance and features to match high-end Intel 13th and 14th gen CPUs. Our testing shows the Core i9-14900K as the fastest overall processor with its 24-core beastly power, although its high price and power consumption limit appeal. For most builders, the Core i7-14700K and 13900K offer nearly as impressive speeds for over $100 less, making them better balanced options. More budget-friendly choices like the 13700K and 13600K still pair nicely for primarily gaming rigs. All of these processors allow you to tap into the advanced cooling, power delivery, PCIe 5.0 support and connectivity of the premium Z790-E motherboard. So choose based on your budget and needs – you really can’t go wrong performance-wise with any modern high-end Intel CPU combined with this capable ASUS ROG board as the foundation for an incredible PC.
