The battle for supremacy in games between Intel and AMD has never been as intense as it is now, but AMD has a new ace in the hole. AMD is $ 449 Ryzen 7 5800X3D (opens in a new tab) uses a new state-of-the-art 3D-ordered SRAM technology called 3D V-Cache to enable a total of 96MB of L3 cache, which unlocks tremendous gaming performance, displacing Intel’s expensive $ 738 Core i9-12900KS as the fastest of the best processors for games – but at a more forgiving price. AMD has achieved this feat with an octa-core 16-thread chip based on the same 7nm process and Zen 3 architecture as the original Ryzen 5000 chips, which debuted in 2020, but uses innovative hybrid connectivity technology to merge an extra piece of cache on top of the processor. cores, first for desktops.
The Ryzen 7 5800X3D is the company’s latest hurray for its long-lasting Socket AM4 platforms, which took Ryzen chips from their inception with the Ryzen 7 1800X in 2017 to their once dominant position at the top of our gaming hierarchy as a benchmark last year. with Ryzen 9 5900X.
AMD’s chips held the lead in every measure until Intel released its Alder Lake range last year, with Intel’s Core i9-12900K becoming the fastest gaming processor we’ve ever tested. However, as AMD is ready to release the 5800X3D, Intel has tried to establish itself at the top of the gaming performance charts with its new special edition Core i9-12900KS. It hit the market a week before the 5800X3D with gain speeds of up to an incredible 5.5 GHz, a record high for computers, and in just over a week, it it was the fastest desktop chip categories.
| Price | Kernels | Threads | Base / gain (GHz) | Total L3 cache | TDP | |
| Ryzen 7 5800X3D | $ 449 | 8 | 16 | 3.4 / 4.5 GHz | 96MB | 105W |
| Core i9-12900KS | $ 739 | 16 cores / 24 threads | 3.4 / 5.5 (P-cores) – 2.5 / 4.0 (E-cores) | 30MB | 150W / 241W |
| Core i9-12900K / KF | $ 589 (K) – $ 564 (KF) | 16 cores / 24 threads | 3.2 / 5.2 (P-cores) – 2.4 / 3.9 (E-cores) | 30MB | 125W / 241W |
However, Intel’s short-lived gaming advantage came at the cost of extra power: the Core i9-12900KS has a base CPU power (PBP) of 150W, a record for a mass desktop processor, and we measured up to 300W of full-power power consumption. In contrast, the Ryzen 7 5800X3D has a 105W TDP rating and a maximum power of 130W in our tests, which shows that it is a far cooler processor that will not require as expensive premises as a powerful cooler, motherboard and power supply. as Core i9-12900KS.
The 96MB L3 cache of the Ryzen 7 5800X3D is transparent to the operating system, which means it doesn’t need special gadgets from the OS or software, but it’s not useful for all games. However, we saw great growth in almost every title we tested.
Here’s a quick snapshot of the average performance of the 5800X3D in our test suite for games and key single- and multi-threaded applications. You’ll find much more extensive testing on the following pages, but that gives you a good idea of how the Ryzen 7 5800X3D performs.
As you can see, the Ryzen 7 5800X3D holds the crown as the fastest gaming chip in our test suite and is in line with AMD’s claim that 3D V-Cache provides an increase in gaming performance equivalent to what we would normally only see from a new microarchitecture. However, the 58000X3D is not as fast as comparable chips in other types of single and multi-threaded non-gaming. This is because other models have an advantage in the number of cores and frequency. In fact, due to the lower clock speeds than its most comparable counterpart, the Ryzen 7 5800X, 5800X3D is slower in some single-threaded applications.
However, while the Intel 12900KS still provides leading performance in applications, its huge $ 739 premium is not as good to buy as AMD’s Ryzen 7 5800X3D at $ 449 if you’re only interested in gaming. The same goes for the standard 12900K and 12700K, although the Core i7-12700K is a contender if you’re looking for a more balanced combination of gaming and app performance at around $ 410.
Of course, the Ryzen 7 5800X3D is a huge win if you already own a Ryzen system – this chip will fit into almost any AM4 motherboard, saving some money if you have the right support components. Overall, the Ryzen 7 5800X3D is exactly what AMD says it is – a gaming-optimized chip that takes the lead.
First, let’s take a quick look at the specs, then move directly to our full game and application test results. Be sure to look for details on deep diving and 3D V-Cache testing, frequency amplification and thermals later in the article (the latter is particularly interesting).
AMD Ryzen 7 5800X3D Specifications and Prices
The Ryzen 7 5800X3D is the first consumer processor to include 3D V-Cache, but the company is also using technology for its Milan-X processors for the data center. 3D V-Cache uses a new technique that uses hybrid connectivity to merge additional 64MB of 7nm SRAM cache vertically onto the Ryzen computing chip, thus tripling the amount of L3 cache per Ryzen crystal.
| Street / MSRP | Kernels | Threads | P-Core Base / Boost | E-Core Base / Boost | L3 Cache | TDP / PBP / MTP | DDR4-3200 | |
| Core i9-12900KS | $ 739 | 8P + 8E | 16 cores / 24 threads | 3.4 / 5.5 GHz | 2.5 / 4.0 GHz | 30 MB | 150W / 241W | DDR4-3200 / DDR5-4800 |
| Core i9-12900K / KF | $ 589 (K) – $ 564 (KF) | 8P + 8E | 16 cores / 24 threads | 3.2 / 5.2 GHz | 2.4 / 3.9 GHz | 30MB | 125W / 241W | DDR4-3200 / DDR5-4800 |
| Ryzen 9 5900X | $ 450 ($ 549) | 12P | 24 threads | 3.7 / 4.8 GHz | – | 32MB | 105W | DDR4-3200 |
| Ryzen 7 5800X3D | $ 449 | 8P | 16 threads | 3.4 / 4.5 GHz | – | 96MB | 105W | DDR4-3200 |
| Ryzen 7 5800X | $ 350 ($ 449) | 8P | 16 threads | 3.8 / 4.7 GHz | – | 32MB | 105W | DDR4-3200 |
| Core i7-12700K / KF | $ 409 (K) – $ 384 (KF) | 8P + 4E | 12 cores / 20 threads | 3.6 / 5.0 GHz | 2.7 / 3.8 GHz | 25MB | 125W / 190W | DDR4-3200 / DDR5-4800 |
| Ryzen 7 5700X | $ 299 | 8P | 16 threads | 3.4 / 4.6 | – | 32MB | 65W | DDR4-3200 |
The Ryzen 7 5800X3D comes with the same eight Zen 3 cores and 16 threads as the standard Ryzen 7 5800X, but has a lower base of 3.4 GHz and a gain of 4.5 GHz within its 105 W envelope. AMD reduce 400 MHz from the base clock and 200 MHz from the boost frequency, but you get an extra 64MB of L3 cache in return, for a total of 96MB of L3.
Naturally, 3D V-Cache technology has its trade-offs, the most obvious being the $ 449 price tag – you’ll pay an extra $ 100 for the same number of cores as you would get in the vanilla Ryzen 7 5800X.
The big attraction of the 5800X3D is AMD’s claim of an average gain of 15% in gaming performance over AMD’s fastest gaming chip, the Ryzen 9 5900X, which also currently sells for $ 450. 3D V-Cache doesn’t increase productivity in other non-gaming jobs, so compared to the 5900X, you’ll sacrifice four cores and eight threads in exchange for extra cache, thus losing performance in some performance applications. This means that the Ryzen 9 5900X would be a better performance-oriented option, but you should also look at Alder Lake’s alternatives if you’re looking for a more balanced performance profile.
The 5800X3D fully supports memory overclocking and Infinity Fabric, but you can’t overclock the CPU cores or use the Precision Boost Overdrive feature to automatically overclock (more details below). The company cites a voltage limitation, but our thermal testing below certainly suggests that heat dissipation is an exacerbating problem. AMD says this is the first iteration of the technology and it is possible that overclocking will be activated on potential future 3D V-Cache processors. However, the company has not officially committed to launching other models in the future. Given the performance we’ve seen, it won’t be surprising to see this technology move into the Zen 4 era.
However, this will not stop enterprising enthusiasts from trying. We’ve already seen reports of limited BCLK overclocking, which can extract a few hundred extra megahertz (perhaps more on motherboards with external clock generators), and there seems to be a workaround to change the motherboard’s output voltage to the CPU, thus powers a chip with a higher voltage than anticipated by AMD. Of course, the latter can carry a significant risk, but we will learn more in the coming weeks as enthusiasts pass silicon through the squeezing machine.
As with all 105W Ryzen 5000 chips, the Ryzen 7 5800X3D is not available with a cooler. The chip has the same thickness (Z-height) as all other Ryzen 5000 models, so it is compatible with the wide ecosystem of standard coolers for the AM4 socket. The 5800X3D will be part of existing 400 and 500 series motherboards (Socket AM4), and upcoming AMD BIOS updates will also allow support for older 300 series platforms. You’ll need a BIOS with AGESA 1.2.0.6b (or higher) -new version) for Ryzen 7 5800X3D.
AMD says support for the Ryzen 5000 will vary by vendor, as well as the timeline for new BIOS revisions. However, they all need to be available now. It should be noted that these BIOS revisions will also include the correction of AMD’s fTPM stuttering issues.
The 5800X3D also doesn’t support the latest connectivity options, such as DDR5 and PCIe 5.0, which you’ll find with Alder Lake, but it does support up to DDR4-3200 and PCIe 4.0. AMD will not be able to handle Intel’s connectivity technology until its 5nm Ryzen 7000 ‘Raphael’ Zen 4 processors arrive later this year.
Let’s take a closer look at the overall architecture, power and thermal characteristics, including thermal control tests, and then move on to our games and applications tests.
