AMD didn't need to release a new CPU. It already makes some of the best gaming CPUs you can buy, and given the weak competition from Intel, AMD could sit idly by and watch the money (and market share) roll in. But it went ahead and released the Ryzen 9 9950X3D anyway, and it feels like the first time AMD's 3D V-Cache tech has been fully realized.

With a new approach to stacking cache on the die and the improved speed of the Zen 5 architecture, the Ryzen 9 9950X3D delivers productivity and gaming performance in equal stride. And unlike last-gen's Ryzen 9 7950X3D, it makes very few compromises along the way.

AMD sent us the Ryzen 9 9950X3D for review. It had no input on the contents of this article.

AMD Ryzen 9 9950X3D pricing and availability

There aren't a lot of surprises with the Ryzen 9 9950X3D. AMD is running back the playbook that we saw in the previous generation, pricing the X3D flagship at $699, which is $50 more than the base Ryzen 9 9950X. That's exactly what we saw in the previous generation. The chip officially launches on March 12, though I suspect it'll sell out quickly. Thankfully, AMD has done a good job replenishing stock of its last-gen X3D options over the past year, and I don't expect that to change this time around.

In an ideal world ruled by list price, the Ryzen 9 9950X3D is great. The additional performance offered by 3D V-Cache is well worth spending an extra $50. That's not the reality of the situation, though. At the time of writing, the base Ryzen 9 9950X is selling for around $540. Meanwhile, the gaming-focused Ryzen 7 9800X3D is selling for around the same price, while the last-gen Ryzen 9 7950X3D has shot up to $740.

Just like the previous generation, you can save around $150 by choosing between productivity and gaming performance. These are all very powerful CPUs, no doubt, but the Ryzen 9 9950X3D comes with a real-world premium with its balance of productivity and gaming performance. If you're able to choose one lane, I'd suggest you do so to get the best bang for your buck.

Intel isn't a factor in this conversation, unfortunately. Its flagship Core Ultra 9 285K is available for $600, so it's cheaper than the Ryzen 9 9950X3D. However, it also falls behind in both productivity and gaming performance with its efficiency-focused architecture. AMD does a lot to justify spending the extra $100 on the Ryzen 9 9950X3D, and Intel doesn't have a true alternative that strikes the balance between gaming and productivity performance like this chip does.

How 3D V-Cache changes the CPU game

A new design leads to big wins

The Ryzen 9 9950X3D builds on AMD's existing Zen 5 lineup with the inclusion of second-gen 3D V-Cache. Like the 3D V-Cache of yore, the idea is to stack additional cache directly on top of the CPU die to improve gaming performance, and as CPUs like the Ryzen 7 7800X3D prove, it's a winning strategy. This is the second generation of 3D V-Cache, though, and it comes with one significant change.

Instead of stacking the additional cache on top of the CPU die, AMD places the cache under the die. That's a big difference, especially for a 16-core chip like the Ryzen 9 9950X3D. With this design, the CPU cores have direct contact with the integrated heat spreader (IHS) on the chip, giving the cores direct access to cooling. This change allows the Ryzen 9 9950X3D to reach a maximum boost clock of 5.7GHz, just like the original Ryzen 9 9950X. It also means you can overclock the chip, which is something that's either been absent or heavily restricted on previous 3D V-Cache chips.

Although AMD would have you believe this is the Ryzen 9 9950X, just with faster gaming performance, there's a little more nuance to the chip. As my testing results show, this is a CPU made for those who want productivity and gaming performance in equal strides but with some reasonable compromises along the way. You're not getting the absolute best performance in either category, but you can get very close in both. That's the secret sauce that makes the Ryzen 9 9950X3D tick.

On the gaming front, the main loss comes from the use of dual core complex dies (CCDs). The Ryzen 9 9950X3D, just like its non-X3D counterpart, has two CCDs, both of which house eight Zen 5 cores. The Ryzen 7 9800X3D, with its eight Zen 5 cores, only has a single CCD. Using two CCDs causes a small amount of additional latency, slightly reducing gaming performance. This is something we've seen play out with the past several generations of AMD chips, and the Ryzen 9 9950X3D isn't changing that story.

AMD has done a fantastic job at making the technical details of 3D V-Cache chips as seamless as possible.

To counteract the performance loss, AMD only places the additional cache on top of one of the CCDs. The idea is to basically have the Ryzen 9 9950X3D act like a Ryzen 7 9800X3D when you're playing games, and like a Ryzen 9 9950X when you're using heavily-threaded applications. AMD has mostly realized that idea with the Ryzen 9 9950X3D, too, largely due to the use of second-gen 3D V-Cache. In the previous generation, with the Ryzen 9 7950X3D, you sacrificed a decent chunk of productivity performance, but that's not the case here.

Still, there are compromises, and they aren't always consistent. With the dual-CCD design and only one of them leveraging 3D V-Cache, there are some scheduling hurdles you'll occasionally run into. AMD has done a fantastic job at making all of these technical details as seamless as possible with drivers specific to 3D V-Cache chips.

But issues can still crop up. For instance, the Ryzen 9 9950X3D calls for the Balanced power mode in Windows 11 for the best performance, and it leverages the Xbox Game Bar for core parking while you play games. Particularly around new Windows updates, you'll have to check in on Game Bar and your power plan to make sure everything is set properly. It's not a big deal, but it's something to consider if you want to pick up the Ryzen 9 9950X3D.

The Ryzen 9 9950X3D smokes everything

It's fast in both gaming and productivity

Alright, enough build-up. Let's get to the numbers. The Ryzen 9 9950X3D delivers exactly what AMD promised, offering massive gains in gaming performance compared to the Core Ultra 9 285K and AMD's own Ryzen 9 9950X, all while keeping pace with other flagships in productivity performance. You make a few compromises depending on the application, but the differences are minor. Unlike first-gen 3D V-Cache, there isn't an obvious gap in productivity performance that's filled by the non-X3D part.

For all the results here, you can see the test bench I used below. This is all fresh data, run on the exact same test bench, and with a fresh copy of Windows 11 installed when swapping the CPU.

Productivity performance is what really shocked me when testing the Ryzen 9 9950X3D. Although AMD is running back the same playbook that we saw in the previous generation, this is the first time we've seen second-gen 3D V-Cache on a dual-CCD chip. The performance advantage is immediately apparent, and it reaches across applications. You can see it most clearly in rendering applications like Cinebench R24 and Blender. AMD is matching — and sometimes exceeding — what it offered with the Ryzen 9 9950X. That's mighty impressive.

Intel isn't posing much competition here, either. Sure, the results are close in apps like Cinebench R24 and Premiere Pro. But that's quickly counteracted when you look at Blender, 7-Zip, Geekbench 6, and Photoshop, all of which show a massive disadvantage for Intel's flagship chip.

The productivity performance here is stellar, but I don't want to move on without highlighting the Premiere Pro score. The base Ryzen 9 9950X is 9% ahead of the Ryzen 9 9950X3D, and that's nothing to sneeze at. This result alone isn't enough to say the Ryzen 9 9950X is faster — Cinebench, 7-Zip, and Geekbench quickly disprove that — but Premiere Pro is an important application. It's large enough to overshadow the other results here if you use it frequently enough.

The most you can ask of the Ryzen 9 9950X3D is that it keeps pace with the Ryzen 9 9950X, however, and AMD certainly succeeded on that front. 3D V-Cache is focused on gaming, after all, and that's where the fascinating performance results are.

No ifs, ands, or buts — the Ryzen 9 9950X3D clobbers the base Ryzen 9 9950X when it comes to gaming performance. Intel's Core Ultra 9 285K is even further behind. But what's particularly impressive is the give and take between the Ryzen 9 9950X3D and Ryzen 7 9800X3D. One isn't clearly faster than the other, which isn't what I expected to see.

My assumption was that the single-CCD chip would offer better gaming performance, and titles like Cyberpunk 2077 and F1 2022 definitely leave that impression. Overall, though, the CPUs trade blows. Some games benefit from lower latency, such as Cyberpunk 2077, while others, such as Hitman 3, appreciate the higher core count of the Ryzen 9 9950X3D. It took a couple of generations and an entirely new version of 3D V-Cache, but the Ryzen 9 9950X3D feels like a proper realization of what this class of CPU should be.

Gaming performance, especially for a CPU, doesn't solely come down to the average frame rate. Consistency is important, too, and that's another area where AMD wins with the Ryzen 9 9950X3D. You can see the frame time across a run of Cyberpunk 2077 above. Here, I'm looking at the time between each frame and focusing particularly on consistency. A big spike in frame time shows a big dip in frame rate, which manifests as a stutter in your game. Thankfully, there's not an example of that kind of frame time spike to point to here.

The same was true in Counter-Strike 2, despite slamming the CPU with an average frame rate above 500 fps. There are minor peaks and valleys in both games, but this is raw data plotted out on a line chart — I didn't clean up the outliers at all. This is excellent consistency, and throughout my time with the Ryzen 9 9950X3D, I didn't notice any clear stuttering in the games I tested.

Power and thermals are under control

Hot and power-hungry, but not worryingly so

The main pitfall with last-gen's Ryzen 9 7950X3D was its limited clock speed. Due to including the extra cache, AMD was forced to limit overclocking capabilities and clock speeds. That's not the case with second-gen 3D V-Cache. AMD claims that the Ryzen 9 9950X3D can hit the same 5.7GHz boost clock as the original Ryzen 9 9950X, and my results back up that claim.

You can see in a 10-minute run of Cinebench R24's single-core test that the Ryzen 9 9950X3D ramped up to 5.7GHz and remained there throughout the duration of the test. Those drops you see are just a result of the data reporting; the chip maintained 5.7GHz on a single core without issue, all while staying below 30 degrees Celsius and 50W of power.

When slamming all of the cores, the results are a bit different but still impressive. In an all-core Cinebench workload, the average clock speed across cores hovered around 5.2GHz. The power and temperature are what's important here, though. With a 360mm all-in-one liquid cooler, the Ryzen 9 9950X3D remained comfortably below 80 degrees Celsius. The power draw was a different story. AMD claims the Ryzen 9 9950X3D tops out at 170W, but my sample ramped up to 200W during this workload.

Cinebench is a stress test, and thankfully, the results aren't as extreme when looking at gaming. You can see in Cyberpunk 2077 above that the results are much more tame in games. The chip sat below 50 degrees for the majority of the test, and it hovered around 110W of power draw. That's excellent efficiency and temperature and a major testament to how big of a difference placing the cache below the cores makes.

Should you buy the AMD Ryzen 9 9950X3D?

You should buy the Ryzen 9 9950X3D if:

• You need gaming and productivity performance in equal stride
• You have a high-performance CPU cooler or plan to buy one
• You can find one at list price

You should NOT buy the Ryzen 9 9950X3D if:

• You primarily need a CPU for gaming or productivity, but not both
• You have a small form factor PC

AMD is realizing the 3D V-Cache dream with the Ryzen 9 9950X3D. It takes a few hits in productivity and gaming performance against the Ryzen 9 9950X and Ryzen 7 9800X3D, respectively, but those are counteracted by stellar performance in other apps. It's the best of both worlds, and that's exactly what AMD wants the Ryzen 9 9950X3D to be.

It's not right for everyone, though. A stronger focus on gaming or productivity will net you about $150 in savings, and if you aren't quick to pick up the Ryzen 9 9950X3D at release, you'll likely spend above the list price.
