Introduction
Let’s take a look at how the new AMD Ryzen 7 7700X3D CPU (released in 2026) compares to its bigger brother, the higher-clocked AMD Ryzen 7 7800X3D CPU. That’s right, AMD has released a new AM5 Zen 4 CPU in 2026, and it is the AMD Ryzen 7 7700X3D, based on AMD’s 3D V-Cache technology. The AMD Ryzen 7 7700X3D was announced at Computex 2026 and then launched in mid-July of 2026. It is based on an 8-core/16-thread configuration, Zen 4 architecture, and 96MB of L3 Cache. It sits just below the AMD Ryzen 7 7800X3D, with lower clock speeds, and competes at an MSRP of $329. We have purchased our own retail Ryzen 7 7700X3D so that we can test its gaming performance and see how it compares to other CPUs. This is the first of several comparison reviews, followed by a final overall review with non-X3D comparisons.
In our performance comparison review today, we are going to take the AMD Ryzen 7700X3D and compare it directly to the Ryzen 7 7800X3D to see the actual game performance differences. This review is primarily focused on game performance, with 12 games tested at 1080p on a GeForce RTX 5090 FE so that we can isolate CPU performance differences and not be bound by GPU performance. All of the games are being tested with real-world, in-game manual benchmark runs, no automatic benchmark modes; we are using actual gameplay. All performance has been tested new and fresh for this review; everything is tested at the time of review, with current BIOS, drivers, game versions, and software.
Though this is a primarily focused gaming performance review, we are also going to include some system benchmarks as well that test multi-core and single-core performance. In this way, you can also gauge how different the CPUs are when it comes to system or rendering usage outside of games. We are also going to look at the CPU Wattage at maximum multi-threaded performance, as well as while gaming. We will also look at temperature as well. Naturally, these are X3D CPUs, though, and meant for the best gaming experience. As stated, we have more comparisons coming, so stay tuned to our site.
AMD Ryzen 7 7700X3D
At its heart, the AMD Ryzen 7 7700X3D is based on the Zen 4 architecture, which powers the AMD Ryzen 7000 series of CPUs. The Zen 4 architecture was launched in September 2022 with the AMD Ryzen 9 7950X at the high end. It wasn’t until February of 2023 that AMD debuted its first AM5 X3D CPU, the AMD Ryzen 9 7950X3D. It was then followed up in April with the launch of the AMD Ryzen 7 7800X3D, the 8-core/16-thread variant, which launched at an MSRP of $449. The Ryzen 7 7800X3D has a single CCD, and this is where the extra L3 3D V-Cache lies. In a similar configuration, the AMD Ryzen 7 7700X3D is configured in the exact same way, with a single-CCD with extra L3 3D V-Cache of the traditional, first-generation variety.
The AMD Ryzen 7 7700X3D sits just below the Ryzen 7 7800X3D and differs from it only in clock speed. The primary difference is that the AMD Ryzen 7 7700X3D has a base frequency of 4GHz and a Turbo Clock Boost frequency of up to 4.5GHz. By comparison, the AMD Ryzen 7 7800X3D has a base frequency of 4.2GHz and a Turbo Clock Boost frequency of up to 5GHz. The Ryzen 7 7700X3D multiplier is 40x, while the Ryzen 7 7800X3D multiplier is 42x. The TDP and PPT are exactly the same for both CPUs: 120W TDP and 162W PPT. Both CPUs are based on a single-CCD of 8-cores/16-thread capability. Both CPUs have the same shared L3 cache size of 96MB. Both CPUs are based on TSMC’s 5nm manufacturing process. The AMD Ryzen 7 7700X3D is literally just a downclocked Ryzen 7 7800X3D, but at a lower MSRP of $329 versus $449.
The AMD Ryzen 7 7700X3D comes in a large box, well protected, but no cooling fan is included. Like every other AM5 CPU, it is shaped and looks exactly the same and installed perfectly into our AM5 motherboard with no issues.
We can see that the AMD Ryzen 7700X3D is based on the Raphael (Zen 4) architecture. The MAX TDP is 120W, and all cores read correctly. We have our DDR5 set to 6000MT/s. The clock speeds are reading up to 4.5GHz for the Boost Max and PBO Max, which is at the default on the motherboard.
