AMD Ryzen 9 7950X3D CPU Review Ft. MSI MAG X670E Tomahawk – The Most Efficient High-End CPU

AMD Ryzen 7000 X3D Desktop CPU Family - 3D Boosted Zen 4

Last year, AMD introduced the Ryzen 7 5800X3D, a CPU that was designed to offer the best value and performance to gamers by leveraging 3D V-Cache technology which allows AMD to stack large pools of cache on top of Zen chiplets, driving up performance in bandwidth starved games & applications. The benefit was clear right from the beginning with reviews showing a huge gaming performance boost that matched and even exceeded Intel's fastest CPU, the Core i9-12900K, at the time.

With the Ryzen 7000 X3D parts, AMD plans to repeat that and give gamers another boost that could potentially make AM5 the fastest platform to game on.

AMD Ryzen 7000 X3D 'Zen 4' 3D V-Cache Desktop CPUs Features:

• Minor optimization on TSMC's 5nm process node
• Up to 64 MB of Stacked cache per CCD (96 MB L3 per CCD)
• Increase In Gaming Performance (Avg & Mins)
• Compatible With AM5 Platforms

AMD Ryzen 7000 X3D CPU Lineup & Specifications

The AMD Ryzen 7000 3D V-Cache CPUs are the 2nd generation consumer V-Cache parts featuring stacked cache. While the Zen 3 lineup featured just one 3D V-Cache SKU, the Zen 4 lineup is getting three SKUs at vastly different prices.

AMD Ryzen 9 7950X3D - 16 Cores With 144 MB Cache

Starting at the top, we have the AMD Ryzen 9 7950X3D which will be the flagship and the first 16-core CPU to feature 3D V-Cache technology. The chip will incorporate a total of 32 threads, a total of 144 MB cache (64 MB CCD, 64 MB V-Cache + 16 MB L2), and a TDP of 120W. As for the clocks, the chip is rated at a base clock of 4.2 GHz which is 300 MHz slower than the standard 7950X but boost clocks are rated at the same 5.7 GHz. This should give us a hint at why the TDP is 50W lower versus the Non-3D part.

The way AMD is arranging the 3D V-Cache structuring on the Ryzen 9 X3D parts is by putting the SRAM cache on a single CCD instead of both CCDs. This way, AMD can maximize the performance in gaming through a single CCD while retaining the secondary die to benefit from the higher clock speeds (1T). This means that there should be a balance of single-threaded gaming performance & multi-threaded applications without sacrificing overall clock speeds like the previous gen.

AMD Ryzen 9 7900X3D - 12 Cores With 140 MB Cache

The second chip is the AMD Ryzen 9 7900X3D which will feature 12 cores and 24 threads. This is also a 2 CCD configuration with one CCD configured with the V-Cache and the second without it. The chip features a total of 140 MB cache (64 MB CCD, 64 MB V-Cache + 12 MB L2). The clocks are rated at a 4.4 GHz base which is 200 MHz slower than the Non-3D SKU & the boost clock remains the same at 5.6 GHz. The CPU is also rated at a TDP of 120W.

Lastly, we have the successor to the Ryzen 7 5800X3D, and the Ryzen 7 7800X3D. This CPU is going to be the ideal choice for gamers with 8 cores, 16 threads, and the same 104 MB of cache (32 MB CCD, 64 MB V-Cache + 8 MB L2). The CPU comes with a base clock of around 4 GHz which could end up at least 500 MHz slower than the Ryzen 7 7700X and a boost clock of 5.0 GHz which is 400 MHz slower than the Ryzen 7 7700X.

AMD Ryzen 7000 X3D CPU Performance

In terms of performance, AMD hasn't shared a whole lot of data which is fair since they want the independent tech industry to test these chips out later this month and showcase their own data rather than relying on official figures. We did get to see performance numbers for the two Ryzen 7000 X3D CPUs, the Ryzen 9 7950X3D and Ryzen 7 7800X3D.

AMD compared the Ryzen 9 7950X3D CPU to Intel's top Core i9-13900K across several gaming and workload apps. The results show that the 3D V-Cache chip can offer up to 24% faster performance in gaming at 1080p with high image quality. Following are the game tests and the respective gains over the 13900K CPU:

AMD Ryzen 9 7950X3D Gaming Performance Test (via AMD):

• Watch Dogs Legion (1080p) - Up To 9% Faster
• DOTA (1080p) - Up To 11% Faster
• Rainbow Six Siege (1080p) - Up To 13% Faster
• Horizon Zero Dawn (1080p) - Up To 24% Faster

As we mentioned above, the 7950X3D chips have a different CCD configuration with one running at higher clocks and the other with conservative limits set in place due to the 3D V-Cache stacking. But that doesn't change the overall performance a lot even in workload apps as the chip can outclass a Core i9-13900K CPU in various tests as shown below:

AMD Ryzen 9 7950X3D Workload Performance Test (via AMD):

• File Encryption (VeraCrypt AES) - Up To 4% Faster
• 3D Graphics (PassMark 10) - Up To 11% Faster
• Adobe Premiere Pro (Playback) - Up To 17% Faster
• DaVinci Resolve (Extended Score) - Up To 24% Faster
• File Compression (7-Zip) - Up To 52% Faster

Lastly, we have the AMD Ryzen 7 7800X3D which has been compared against the Ryzen 7 5800X3D and the results are even more impressive. Using the same 1080p resolution and high-quality preset across various games, the CPU scored a gaming performance lead of up to 30% versus the first-gen X3D CPU. The gains can be seen below:

• Rainbow Six Siege (1080p) - Up To 21% Faster
• Warhammer Dawn of War III (1080p) - Up To 22% Faster
• CS:GO (1080p) - Up To 23% Faster
• Dota 2 (1080p) - Up To 30% Faster

These are definitely big gains for gamers and the addition of the Ryzen 9 parts means that users will not only have the fastest gaming performance around but also the fastest content creation perf.
