For close to four years, AMD has enjoyed an annual cadence of reviews claiming its mainstream, eight-core 3D V-Cache processors are the “world’s fastest gaming processor.” And that’s true. The Ryzen 7 9800X3D is the best gaming CPU you can buy, and it’s not particularly close when looking at the competition from Intel and AMD’s own non-X3D parts. The new Ryzen 7 9850X3D once again claims the crown as the world’s fastest gaming processor, but unlike in years past, where AMD owned that title with overwhelming force, today, it wins by a technicality.

Launching at $499, the Ryzen 7 9850X3D deals in such thin margins that it’s easy to lose it in the shuffle. The Ryzen 7 9800X3D launched at $479, and you can find it for around $465 now. The 12-core Ryzen 9 9900X3D is slightly more, with a street price around $560 now, while the 16-core Ryzen 9 9950X3D maintains its halo product status with a going price of around $670.

The Ryzen 7 9850X3D is spiritually similar to Intel’s usual KS releases; a binned chip with higher clock speeds that isn’t meant for mass-market appeal. The difference compared to Intel’s KS releases — and the issue with the Ryzen 7 9850X3D more broadly — is that it doesn’t target the same market. It’s not a halo product; AMD already has that with the Ryzen 9 9950X3D. And it isn’t a wholly unique entry, offering only marginal gains over the Ryzen 7 9800X3D for a marginally more expensive price and significantly higher power consumption.

Even if prices remain as they are now (and I don’t suspect that’ll happen), it’s hard to conjure a situation where the Ryzen 7 9850X3D is a better choice than the Ryzen 7 9800X3D. There are some stand-out games where an extra 400MHz on the boost clock speed offers high single-digit performance gains, but in many games and apps, the gains are in the low single-digits, if there’s any performance gain at all. If anything, the Ryzen 7 9850X3D looks like a way to keep the price of the Ryzen 7 9800X3D from slipping further, lest it finally drop below the $450 mark.

Our extensive benchmarking will paint a clear picture of what the Ryzen 7 9850X3D offers, or more importantly, what it doesn’t. We have test results for productivity, gaming, and power in the pages ahead, so without further ado.

Ryzen 7 9850X3D Pricing and Specifications

The Ryzen 7 9850X3D is easy to parse because it’s identical to the base Ryzen 7 9800X3D in all but name and clock speed. Like the original model, the Ryzen 7 9850X3D features a single compute die (CCD) with eight Zen 5 cores, with a 96MB chunk of L3 SRAM placed under the CCD. Placing the SRAM under the compute die gives the CCD direct access to the IHS, improving thermal performance and allowing AMD to offer full multiplier-based overclocking, something that wasn’t possible on older 3D V-Cache chips that have the SRAM on top of the compute die. All Zen 5 X3D chips place the SRAM chunk under the CCD.

AMD’s eight-core 3D V-Cache CPUs have been winners dating back to Zen 3, even in the face of the Ryzen 9 7950X3D and Ryzen 9 9900X3D that sport higher core counts. AMD struggled with CCD-to-CCD latency on these chips previously, though AMD driver updates and the shift toward placing the SRAM under the compute die have wrangled those downsides.

The Ryzen 7 9850X3D carries the same 120W TDP as the Ryzen 7 9800X3D, as well as the same 104MB of cache, split across 8MB of L2 and 96MB of L3. Clock speed is the differentiator, with the Ryzen 7 9850X3D sporting a 400MHz lead over the Ryzen 7 9800X3D, clocking at 5.6GHz out of the box without any help from PBO or manual overclocking (both of which are still supported).

Intel still has yet to answer 3D V-Cache, though that could change later this year as Intel is expected to introduce bLLC to its Nova Lake desktop processors. For now, AMD’s X3D chips remain the best for gaming performance, and it’s not particularly close. Double-digit improvements over both Intel and AMD’s own non-X3D chips are expected across games, and are only exaggerated in titles that particularly enjoy more cache to play with.

Competition isn’t much of a concern for the Ryzen 7 9850X3D, at least for everything except the Ryzen 7 9800X3D. This is the first time AMD has re-released an X3D chip with a better bin, and it begs a simple question: Why?

With PBO, a 200MHz boost is already possible on the Ryzen 7 9800X3D, and although you can push the Ryzen 7 9850X3D up by that same 200MHz, the gap between the two chips remains small. AMD tells me that the Ryzen 7 9850X3D is for gamers who want the best of the best, particularly in those frequency-sensitive titles. That may be true, but my read on the situation with the Ryzen 7 9850X3D is slightly different after testing the chip myself.

It seems mainly targeted at OEMs, or perhaps, system builders that haven’t already picked up the Ryzen 7 9800X3D. It’s not dissimilar to the Ryzen 7 5700X3D, though in this situation, moving to a higher bin instead of a lower one. It’s important to keep this context in mind. Using the Ryzen 7 9800X3D as the basis for comparison sets you up for disappointment; this chip was never meant to be an upgrade to AMD’s existing Zen 5 X3D lineup.

With that context in mind, let’s get into the meat of the review with gaming benchmarks, productivity results, and our power and efficiency testing.
