With eight cores and several hundred dollars separating them, it might seem like a foregone conclusion which is best. But with their unique hardware arrangements, the title of which is the best gaming processor of 2022 — so far — really is up for grabs.
Pricing and availability
Jacob Roach / Digital Trends
Intel released the Core i9-12900K in early November 2021 as the flagship of the new Alder Lake generation. It debuted with a recommend price of $589, though it more readily sells for around $600 at the time of writing.
The AMD Ryzen 5800X3D launched on April 20, 2022, with a price tag of $450. This puts it more in line with the Core i7-12700K in terms of cost, but performance-wise, at least in gaming, it is very much gunning for the Intel flagship.
Specs
| AMD Ryzen 5800X3D | Intel Core i9-12900K | |
| Architecture | Zen 3 | Alder Lake |
| Process | TSCM 7nm | Intel 7 (10nm) |
| Cores | 8 | 16 (8 performance + 8 efficiency) |
| Threads | 16 | 24 |
| Base clock | 3.4GHz | 3.4GHz |
| Boost clock | 4.5GHz | 5.2GHz |
| Total L3 cache | 96MB | 30MB |
| TDP | 105W | 241W |
These two CPUs have very different hardware makeups, each representing exciting new directions for their respective companies.
The Ryzen 7 5800X3D has a more traditional core layout of eight identical cores and 16 threads with simultaneous multi-threading. The Intel Core i9-12900K has 16 total cores split between eight performance cores, and eight smaller efficiency cores.
The AMD CPU sports a more modest 4.5GHz boost clock, a 200MHz reduction from the Ryzen 7 5800X it’s based on, while the Core i9-12900K reaches to new heights with a 5.2GHz boost clock on a single core and a 5GHz boost clock across all of them at once.

Where the 5800X3D breaks new ground is in its cache. It has 64MB of 3D-stacked L3 cache on top of the die, which when combined with the normal 32MB, gives it 96MB of total L3 cache. That’s more than three times as much as the Core i9-12900K.
That additional cache dramatically boosts the otherwise standard specifications to new heights of gaming performance. There are some bandwidth- and latency-dependent applications that could also benefit from it, but it’s games where we’re seeing the largest benefit.
Outside of specs, power is a big concern. The Core i9-12900K draws more than twice as much power than the Ryzen 7 5800X3D, and even more if you overclock it. The Ryzen 7 5800X3D doesn’t support overclocking, unfortunately, though that comes with the upside of less power draw overall.
Gaming
The Ryzen 7 5800X3D and Core i9-12900K were both sold as gaming CPUs, so it only makes sense to start there. You can see how the two chips stack up on average in the chart below. Our tests were run at 1080p with an RTX 3090 and 32GB of DDR4-3200 memory. Keep in mind that the Core i9-12900K supports DDR5, though it doesn’t make a huge difference in games.
The extra L3 cache on Ryzen 7 5800X3D makes a big difference, however. Overall, the Ryzen 7 5800X3D is about 1.7% faster than the Core i9-12900K. That isn’t a massive lead, but consider that AMD’s CPU has half of the cores, a much slower clock speed, and costs around $200 less.
It’s not perfect, though. In intense open-world games like Red Dead Redemption 2 and Forza Horizon 4, the Core i9-12900K takes a lead with its larger core count.
Some open-world titles still favor the Ryzen 7 5800X3D’s increased cache, however, as showcased by Far Cry 6 and Assassin’s Creed Valhalla.
| AMD Ryzen 7 5800X3D | Intel Core i9-12900K | |
| 3D Mark Time Spy | 17,078 | 19,396 |
| Red Dead Redemption 2 | 119 fps | 132 fps |
| Assassin’s Creed Valhalla | 121 fps | 118 fps |
| Forza Horizon 4 | 247 fps | 250 fps |
| Fortnite | 205 fps | 205 fps |
| Halo Infinite | 127 fps | 113 fps |
| Cyberpunk 2077 | 128 fps | 122 fps |
| Far Cry 6 | 147 fps | 141 fps |
| Civilization VI (turn time, lower is better) | 6. 6 seconds |
7.3 seconds |
Where the Ryzen 7 5800X3D shoots ahead is in multiplayer. In Halo Infinite, it leads by 12.4%, and in Fortnite, it matches the Core i9-12900K. AMD says the random nature of multiplayer games — think Apex Legends or Valorant — can benefit from increased cache, and our benchmarks back that up.
It’s not just multiplayer titles, either. Our Civilization VI turn time benchmark is a sign of that, showing that an increased cache pool allows the processor to hold more instructions for AI opponents.
Processor performance
Jacob Roach / Digital Trends
Although the Ryzen 7 5800X3D is a showstopping gaming CPU, it’s not great in general processor performance. The higher core count on the Core i9-12900K allows it to run through applications much faster, both in terms of single- and multi-core performance.
| AMD Ryzen 7 5800X3D | Intel Core i9-12900K | |
| Cinebench R23 single-core | 1,460 | 1,989 |
| Cinebench R23 multi-core | 14,544 | 27,344 |
| Geekbench 5 single-core | 1,588 | 2,036 |
| Geekbench 5 multi-core | 10,209 | 18,259 |
| Handbrake (seconds, lower is better) | 69 | 47 |
| PugetBench for Premiere Pro | 882 | 1,066 |
In tests like Cinebench and Geekbench, which exclusively stress the CPU, the Core i9-12900K is about 30% faster in single-core performance and around 80% faster in multi-core performance.
The Core i9-12900K has a lot more general compute heft under the hood.
That translates into applications, too, with Intel’s CPU showing a 21% lead in Premiere and a 32% lead in Handbrake. If you’re a professional that needs optimal CPU performance, the Core i9-12900K is your best bet, especially considering its platform features.
PCIe and memory support
As much as raw performance, cost, and efficiency are major factors in buying a CPU, you also need to factor in the ecosystem. The AMD Ryzen 5800X3D is running on AMD’s aged AM4 platform, which supports DDR4 memory and PCIe 4.0. In comparison, the Core i9-12900K is based on Intel’s newer LGA 1700 socket and supports DDR5 memory and PCIe 5.0. That not only means it has greater performance potential where memory bandwidth is paramount, but that it can be upgraded to future DDR5 and PCIe hardware (GPUs and storage being the most prevalent) without the need to upgrade anything else.
Intel’s platform will also have one more generation of upgrades in Raptor Lake, whereas AMD’s AM4 is very much on its last legs.
It’s still capable and the 5800X3D represents an amazing upgrade path for existing AMD Ryzen system owners, but it’s a harder one to recommend for new builds considering its lack of comparable longevity.
Power and thermals
Jacob Roach / Digital Trends
Performant as it is, the Core i9-12900K is a hot processor. During our tests, it peaked at around 86 degrees Celsius, which is right around where the Ryzen 7 5800X3D peaked. However, Intel’s part drew a staggering 240 watts of power during that time, while the Ryzen 7 5800X3D only sipped 101W.
We ran our tests with a 240mm all-in-one liquid cooler, so there’s a little more thermal headroom with an intense cooling solution. Regardless, the Core i9-12900K is a clear loser here. It draws a lot of power as is, and if you overclock it, it will draw even more. The beefed-up Core i9-12900KS is evidence of that, nearing 300W and 100 degrees Celsius based on our testing.
Ryzen rips for gaming, but Alder Lake is a better all-rounder
Jacob Roach / Digital Trends
If you want the best gaming CPU, the Ryzen 7 5800X3D is the cream of the crop.
When it comes to the best processors, however, the Core i9-12900K still holds the crown. It comes with much higher performance in professional applications, despite taking a decent back seat in gaming.
The main concern comes down to thermals and power. The Core i9-12900K is a hot chip, and you’ll need one of the best PC power supplies to support it. That’s especially true if you’re overclocking, where even a 360mm AIO can only keep temperatures around 90 degrees Celsius when the chip is pushed.
On the other hand, the Ryzen 7 5800X3D doesn’t even support overclocking. That doesn’t make a huge difference in games, but there are still applications that are sensitive to frequency (including older games). Keep that in mind before picking up the CPU you want.

AMD Ryzen 7 5800X3D Vs Intel Core i9-12900K: Which Should You Buy?
AMD’s Ryzen 7 5800X3D processor
Antony Leather
Today AMD (NASDAQ:AMD) has launched its new Ryzen 7 5800X3D — it’s latest mainstream desktop CPU, set to retail for $449, that promises a significant leap in gaming performance compared to the existing Ryzen 7 5800X. In this review of the Ryzen 7 5800X3D, we’ll be looking at performance numbers for the new CPU in games and content creation to see how it stacks up against Intel’s Core i9-12900K and the Ryzen 7 5800X.
Who’s it for?
This is first and foremost a CPU for gamers. It’s most definitely not for anyone that wants to overclock their CPU either as the CPU doesn’t support it. The 3D V-Cache allows for lower latencies and a real lift to performance in situations where the CPU can boost frame rates.
This won’t be everywhere as it depends on the game itself, the resolution and graphics settings, but even at 1080p with a fairly modest graphics card such as the RTX 3070, you’ll see differences between CPUs.
It’s key feature is 3D V-Cache — a stacked portion of cache that boosts the amount of cache considerably compared to its sister CPU, the Ryzen 7 5800X. Apart from this, the Ryzen 7 5800X3D is largely the same as the standard CPU, except to deal with the large amount of extra cache, AMD has had to reign in the frequencies.
That might sound like a bad idea, but it’s banking on the 3D V-Cache more than making up for this in many (but not all) situations. As a result, though, the Ryzen 7 5800X3D is actually a touch slower than the Ryzen 7 5800X in terms of frequencies. The latter can hit 4.7GHz peak boost frequency, while the Ryzen 7 5800X3D is 200MHz slower at 4.5GHz.

What motherboards is it compatible with?
You’ll need a 400 or 500-series chipset motherboard to take advantage of the Ryzen 7 5800X3D form the outset, but AMD has stated that 300-series chipsets will be receiving BIOS updates to allow them to support the Ryzen 5000-series too.
Check with your motherboard web page to confirm compatibility.
What is 3D V-cache?
AMD has utilized what it calls Hybrid Bond 3D interconnects — a two-step bonding between dielectric layers to create stacked layers of components — in this instance, the extra cache directly on top of a Ryzen core complex. This provides three times three time the energy efficiency of standard methods.
AMD’s next big thing with CPUs — 3D chiplets
AMD
The actual interconnects between layers can be over 15 times that of traditional micro bump 3D interconnects and offers even greater density compared to a standard 2D chiplet used to create previous Ryzen CPUs.
AMD’s Ryzen 7 5800X3D has 100MB of total cache thanks to a stacked design where the extra cache sits … [+] on top of the CPU cores.
AMD
It’s not just extra cache that can be stacked, but other components too. It should also be noted that Intel has a similar technology, called Foveros.
AMD’s 3D V-Cache allows for components such as cache to be stacked on top of its core chiplets
AMD
What are the competing CPUs?
At $449, the Ryzen 7 5800X3D is cheaper than Intel’s Core i9-12900K, but pricier than the Core i7-12700K.
Seeing as AMD has made quite a song and dance about the comparison with the Core i9, that’s the CPU I’ll be focusing on today, although it should be noted that even the cheapest version of the Core i9 — the 12900KF — still costs around $100 more than the AMD CPU.
Test system and benchmarks
The test system
Antony Leather
The test system uses the latest drivers and Windows 11 updates that were up to date as of April 12th 2022 and I’ve re-tested every CPU in the graphs too — I’d check every review out there to make sure they state the same as these things do make a big difference to the results. Default BIOS settings were used, but the correct memory settings applied using XMP profiles. You can see graphs with other CPUs here.
The hardware includes an Nvidia RTX 3070, custom water-cooling system featuring Corsair Hydro X components and a Barrow Ropilema test bench. I’ve also used 16GB of Corsair 3466MHz Vengeance Pro RGB memory and 32GB Kingston 5,200MHz Fury DDR5 memory along with an RM850x power supply.
I used an Asus ROG Maximus Z690 Apex motherboard to test the 12th Gen Intel CPUs, and a Gigabyte X570 Aorus Master motherboard to test the AMD CPUs.
Far Cry 6 has, like its predecessors, favored AMD in games so it was no surprise to see the Ryzen 7 5800X3D top the chart here with some impressive frame rates even compared to the Core i9-12900K and significantly faster than the Ryzen 7 5800X. This is despite using an Nvidia RTX 3070, which is powerful but far from the most potent card out there.
Dirt 5 isn’t particularly CPU-bound but there was still small differences, again favoring the new AMD CPU, but it wasn’t any faster than the Ryzen 9 5900X.
Above in Watch Dogs: Legion, there was again a slight uptick in frame rates compared to the Ryzen 7 5800X, but this isn’t a particularly CPU-bound game,
The combined Lightroom and Photoshop benchmark revealed a significant boost from the 3D V-Cache compared to the Ryzen 5800X, so it’s clear that performance hits won’t occur everywhere outside of games due to lower frequencies and some tasks actually benefit from the added cache.
Video encoding isn’t one of those tasks though and if you do a lot of video encoding, the Ryzen 7 5800X is a better option, but clearly for just $100 or so more, the Core i9-12900K is a significantly better option.
Single-threaded performance takes a hit too, likely down to the lower frequencies so it’s clear that either the extra cache plays little to no role in boosting performance here.
Again, in terms of raw multi-threaded performance, the Ryzen 7 5800X3D is slower than the Ryzen 7 5800X and the Core i9-12900K is significantly faster, absolutely justifying the extra outlay.
There was also a slight uptick in power consumption at stock speed, adding a touch over 20W under load compared to the Ryzen 7 5800X.
Conclusion
The Ryzen 7 5800X3D is both weird and wonderful. It does what AMD said it would do — edge out a lead in many games that even the Core i9-12900K can’t match and is definitely the fastest AMD CPU we’ve seen in several games too. However, the lower frequencies compared to the standard Ryzen 7 5800X mean the latter is noticeably faster in some content creation tasks.
This really is a CPU designed for gaming, and that’s quite interesting.
AMD’s Ryzen 7 5800X3D

One issue that did reveal itself in testing, though, were operating temperatures. The test system used custom water-cooling and the CPU still reported a temperature of between 85-90°C under full load across all eight cores. By comparison, the Ryzen 7 5800X and Ryzen 9 5900X struggled to top 60°C in exactly the same system in the same test. It’s clear that this is one hot-running CPU and this is likely one reason AMD had to reign in the temperatures, although stepping down to a standard 240mm liquid cooler didn’t see these thermals rise much so it’s fair to stop short of saying you need monster cooling to tame it. It’s likely just a result of the 3D stacking technology.
The gaming prowess won’t extend to all titles, settings and resolutions either — as we can see in Watch Dogs it’s noticeably quicker than the Ryzen 7 5800X, but the Core i9-12900K was still quicker, at least with this hardware.
It’s clear that AMD has provided a handy, affordable stop-gap for gamers, though, and critically, anyone considering jumping ship to a 12th Gen Intel CPU from an AMD motherboard will see this as a very attractive option given you only need to replace the processor and not the motherboard and potentially cooler and memory too.
AMD has thankfully not increased the price compared to the Ryzen 7 5800X, either, so for gamers, it’s quite a shrewd move. What isn’t great, though, is the content creation performance and heat. Performance in content creation was lower practically across the board than the Ryzen 7 5800X, although the extra cache did seem to help it in Lightroom and Photoshop. Of course Intel’s 12th Gen CPUs are utterly dominant here anyway. Even the Core i5-12600K is signficiantly faster in Cinebench R23’s multi-threaded test — a CPU that costs nearly $200 less.
However, AMD isn’t selling the Ryzen 7 5800X3D as an upgrade in terms of content creation. It has the same underlying Zen 3 architecture as the Ryzen 7 5800X so nothing was going to change much that isn’t impacted by the larger cache.
What is interesting, though, is what 3D V-Cache would mean for future CPUs. Coupled with its next-gen Zen 4 architecture, which should close help solve the poor performance in content creation and potentially fix thermals too, AMD’s next launch could be very interesting indeed.
