Intel Core i7-14700K vs AMD Ryzen 7 7800X3D: What's the Difference?

When building your PC or upgrading your CPU, it's common to ask: "Which is better - AMD or Intel?"

For those looking at CPUs on the higher-end, two CPU models that will frequently come up are the i7-14700K and Ryzen 7800X3D. Rest assured, both are great choices, but they are vastly different in multiple aspects. So, Intel Core i7-14700K vs AMD Ryzen 7 7800X3D: what’s the difference?

Intel Core i7-14700K vs AMD Ryzen 7 7800X3D: Specs

For a quick glance at the comparison, we've got a spec table below. However, there's explanation that must be made before we draw any conclusions based on the specs. We’ll get a bit more in depth about these differences afterward.

Processor Processor Cores Processor Threads Total Cache Peak Clock Speed Base Clock Speed Processor Graphics Total CPU PCIe Lanes
i7-14700K 20 (8 Performance +12 Efficient) 28 33MB Up to 5.6GHz (Performance Cores), 4.3Ghz (Efficient Cores) 3.4 GHz (Performance Cores), 2.5 GHz (Efficient Cores) Intel UHD Graphics 770 20
Ryzen 7 7800X3D 8 16 104MB Up to 5.0GHz 4.2GHz Radeon Graphics 28, 24

Based on the specs, we see the two CPUs are vastly different. While they trade blows on certain specs, we have to do a deeper dive on how they account for real-world performance, such as gaming and productivity.

Intel Core i7-14700K vs AMD Ryzen 7 7800X3D: Performance

At face value, it's easy to judge that the 14700K may easily outperform the 7800X3D based on the clock speeds and number of cores.

However, the 7800X3D shines in more games than the 14700K, due to AMD's 3D V-Cache Technology (hence the "3D" in "7800X3D"). If you compare the specs, you'll notice the 7800X3D has a significantly larger cache between the two.

Thanks to the 7800X3D's cache, we're able to see its benefits with higher frame rates in cache-sensitive games, such as Microsoft Flight Simulator, Red Dead Redemption II, and Assassin's Creed Mirage. Microsoft Flight Simulator for example sees up to a 20% difference. For games that aren't cache-sensitive, the 7800X3D will normally perform on par with the 14700K or slightly lower.

Microsoft Flight Simulator 138 FPS 114 FPS 22%
Red Dead Redemption II 204 FPS 180 FPS 13%
Assassin's Creed Mirage 192 FPS 176 FPS 9%

Intel Core i7-14700K vs AMD Ryzen 7 7800X3D: Productivity

When it comes to productivity tasks such as rendering or photo editing, the 14700K truly shines here. A huge reason for this is due to some productivity tasks/applications being able to fully utilize every available thread of the CPU. Considering the 14700K boasts 28 threads compared to the 7800X3D's 16 threads, we can see why there's a considerable difference for productivity tasks between the two CPUs.

Intel Core i7-14700K vs AMD Ryzen 7 7800X3D: Power

When it comes to power consumption & efficiency, the 7800X3D consumes a considerably lower amount of power. This is due to the 7800X3D's Zen 4 architecture and 5nm process node, which enables a higher transistor density and leads us to a lower power consumption at a performance level equivalent to the 14700K.

To illustrate how efficient the 7800X3D, we've put together a quick table below. These wattage consumption rates were taken from games where the two CPUs had an average FPS that was within marginal error (~2%) of each other.

Intel Core i7-14700K vs AMD Ryzen 7 7800X3D: Price

When taking cost into consideration, at the time of this writing, we have the 14700K's MSRP at $399, while the 7800X3D rings at $449. If shopping at the right time, you'll be able to find the 7800X3D at a more competitive price that would be roughly comparable to the 14700K.

Which to Choose?

For a PC build that will primarily just be utilized for gaming, or for someone who is conscious of their power bill - the Ryzen 7 7800X3D is the ideal choice.

For someone who uses their PC for both gaming and productivity - the i7-14700K would be suitable.

Regardless of which one you pick, it's going to need a cooler as neither of these CPUs come with one. Our iCUE LINK AIOs are the top choice for a vibrant and quiet PC, or perhaps the A115 Air Cooler for those who need the utmost long-term reliability.
