When AMD introduced it could add help for the Ryzen 5000 household to the previous 300 sequence motherboard chipsets it raised attention-grabbing questions on how these chips would carry out when plugged in as upgrades. We suspected CPUs just like the Ryzen 7 5800X3D would possibly show to be unusually robust improve choices because of the massive quantity of onboard L3 cache.
Now that we’ve spent a while evaluating the query, we will verify it: Any fanatic gamer nonetheless operating a Ryzen 7 1800X or beneath ought to severely take into account both the Ryzen 7 5800X or the Ryzen 7 5800X3D as an improve choice. The 5800X3D is a very good selection in case you are caught with slower RAM clocked at DDR4-2667 or beneath. Efficiency enhancements of 1.5x – 2x are potential at 1080p with an appropriately highly effective GPU.
Why the 5800X3D Shines on AMD’s X370 Motherboard Platform
When Ryzen launched, the Ryzen 7 1800X’s formal reminiscence clock help topped out at DDR4-2667. Sooner was potential, however 3.2GHz DDR4 nonetheless commanded a premium over the two.67GHz taste again in 2017 and loads of OEMs follow formally supported clocks. This restricted Ryzen’s efficiency in gaming and different latency-sensitive functions. At this time, DDR4-3600 is fairly customary for a Ryzen system.
One constant attribute of AMD’s Ryzen CPUs over the previous 5 years is that they profit from increased reminiscence bandwidth greater than Intel chips sometimes do. That is very true on an older chip just like the Zen 1-based Ryzen 7 1800X, which supplied every CPU core a comparatively small slice of L3 earlier than leaning on most important reminiscence. As AMD developed Zen 2 and Zen 3, it made varied enhancements to the cache construction of the structure. Zen 2 doubled up on L3 in comparison with Zen 1, whereas Zen 3 debuted Ryzen’s first unified L3 cache. The 5800X3D takes this technique and turbo prices it by bumping the on-die L3 cache as much as 96MB. Because it seems, dropping an additional 64MB of cache on-chip is a nice option to obviate the efficiency hit Ryzen 1 takes when paired with DDR4-2667.
DRAM isn’t terribly costly today — it nonetheless prices much less to purchase a Ryzen 7 5800X + 32GB of DDR4-3600 than it does to purchase simply the Ryzen 7 5800X3D, for instance — however the Ryzen 7 5800X3D has its personal persuasive efficiency argument to make.
To Improve or Purchase New?
The hypothetical gamer with our testbed system configuration constructed a Ryzen 7 1800X when the platform was new, probably pairing it with a GTX 1080 or 1080 Ti. The system has already been upgraded as soon as, with an RTX 3080. System benchmarks now present (as we’ll see) that the Ryzen 7 1800X is bottlenecking sport efficiency in 1080p and even some 1440p video games. Is it value upgrading this older system with a brand new CPU, or is it higher to attend for Socket AM5?
After spending a while with these programs, we’re fairly firmly on Crew Improve. The efficiency enchancment from plugging a Ryzen 7 5800X3D or Ryzen 7 5800X into an previous X370 board is damned spectacular. Fans who need greater than eight cores have choices just like the 16-core Ryzen 9 5950X. That CPU affords the entire single-threaded enhancements within the Zen 3 household, plus twice the utmost variety of cores AMD was promoting in a shopper socket again in 2017. Whereas we concentrate on gaming right here, a fast take a look at software efficiency suggests the Ryzen 7 5800X and 5800X3D are 1.5x – 2x sooner than the Ryzen 7 1800X in each single-threaded and multi-threaded functions.
Be aware: The truth that our Ryzen 7 1800X testbed has already been upgraded to an RTX 3080 has loads to do with why these numbers look the best way they do. The developments on this knowledge are prone to maintain true for the RTX 3060 Ti, RTX 3070, and RTX 3080 in addition to higher-end RDNA2 playing cards within the Radeon 67xx and 68xx households. Excessive-end Turing playing cards just like the RTX 2080 Ti and RTX 2080 would nonetheless present the identical developments, however to a smaller diploma.
Our trusty Asus Crosshair VI Hero got here out of retirement for this testing. We up to date to the AGESA 126.96.36.199b UEFI (v.8503) out there on the Asus web site. Whereas Ryzen 5000 help isn’t formally set to reach till AGESA 188.8.131.52, we have been instructed that the AGESA 184.108.40.206b model ought to nonetheless help the CPUs, although presumably with some limitations. After testing the board, we’re assured sufficient in these numbers to launch them. The AGESA 220.127.116.11 replace could enhance compatibility and additional enhance efficiency, however the efficiency enchancment out there in the present day is greater than sufficient to justify the improve.
We had no crashes or stability issues when testing the Ryzen 7 5800X and 5800X3D, however we did observe one challenge: Whereas the 5800X had no downside with a DDR4-3600 reminiscence clock, the 5800X3D was constantly a bit slower when examined at DDR4-3600 versus DDR4-2667. After speaking to Asus, we’re chalking this as much as the early UEFI model.
Whereas it could’ve been good to have the DDR4-3600 numbers for the Ryzen 7 5800X3D, the DDR4-2667 numbers are adequate to run on their very own. Since we don’t have DDR4-3600 numbers for the 5800X3D on X370, we pulled within the knowledge set we used for our 5800X3D evaluation on an MSI X570 motherboard again in April. Utilizing that knowledge is a useful option to spotlight the efficiency variations between the X370 and X570 chipsets. Resizable Bar will not be supported on the Asus Crosshair VI Hero and was not enabled on that platform. Our X570 exams do embrace Resizable Bar help.
Usually we embrace a good variety of software exams, however we stored this evaluation centered on gaming. First, that’s the market AMD is explicitly focusing on with the Ryzen 7 5800X3D. Second, CPU gaming efficiency is notoriously troublesome to enhance in comparison with different workloads, and gaming is the world the place the Ryzen 7 1800X was weakest at launch. Third, we needed to measure the impression of AMD’s massive L3 cache in a low reminiscence bandwidth situation and gauge the efficiency distinction between the 5800X3D and 5800X.

Our outcomes are fairly totally different relying on the decision you goal.
At 1080p, the Ryzen 7 5800X is 1.35x sooner than the Ryzen 7 1800X when each are outfitted with DDR4-2667 RAM. The 1800X’s efficiency improves by 1.14x when its paired with sooner RAM, whereas the 5800X picks up simply 1.09x from the identical improve. When each programs are outfitted with DDR4-3600, the 5800X is 1.28x sooner than the 1800X at 1080p.
The Ryzen 7 5800X3D is the star of this explicit present. It’s a minimum of 1.6x sooner than the 1800X when each are outfitted with DDR4-2667, and it’s nonetheless 1.09x sooner than the 5800X when the latter has the benefit of DDR4-3600. Solely the X570-based 5800X3D system is a measly 5 p.c sooner, and we’re chalking no less than a few of these beneficial properties as much as the X570 chipset’s Resizable Bar help.
Players with 1080p and 1440p displays have explicit cause to eye the 5800X and/or the 5800X3D. At 1440p we count on to see decision and element settings hit the GPU exhausting sufficient to dampen the CPU’s relative contribution to system efficiency. Regardless of this, the 5800X3D nonetheless manages to be 1.37x sooner than the Ryzen 7 1800X at 1440p and 1.12x sooner than the 5800X. As soon as once more, the X570 platform is the general chief, however solely by 5 p.c.
The 4K Query
When the Ryzen 7 1800X launched, there have been issues over whether or not or not it could be able to driving trendy GPUs at 4K. AMD insisted on the time that the Ryzen 7 1800X may hold with top-end CPUs on the highest resolutions. 5 years later, that’s nonetheless (largely) true. Whereas it falls nicely behind the competitors in 1440p and 1080p, 4K at excessive element ranges nonetheless stresses the GPU rather more than the CPU. Higher UEFI help for the Ryzen 7 5800X3D may need improved efficiency a bit of, however the hole between X370 and X570 is barely 4 p.c.
The 1.13x hole between the Ryzen 7 1800X and the 5800X3D at 4K is skewed by Ashes of the Singularity. Take away it from the typical and there’s solely a 7 p.c hole between the Ryzen 7 1800X and the Ryzen 7 5800X3D. Under this decision, the 1800X will get pummeled fairly badly, although it nonetheless drives each sport at eminently playable body charges.
The Ryzen 7 5800X and 5800X3D are attention-grabbing improve choices for early Ryzen adopters, particularly early adopters who don’t have high-speed DRAM and who primarily sport in 1080p. A Ryzen 7 5800X3D outfitted with DDR4-2667 is roughly 10 p.c sooner than a Ryzen 7 5800X + DDR4-3600. If we assume an $80 value level for brand new DRAM (together with transport) and borrow Newegg’s value for each CPUs as of 6/5/2022, the fee comes out to $394 for the 5800X + DDR4-3600 versus $470 for the Ryzen 7 5800X3D alone. That makes the 5900X3D a median of 1.09x sooner in 1080p, whereas costing 1.19x extra. That’s not the perfect value/efficiency ratio on Earth, however high-end chips from Intel, AMD, and Nvidia all carry premiums.
Whereas this story doesn’t take into account Zen+ CPUs on the X470 chipset, there’s no cause these programs wouldn’t profit equally. Absolutely the diploma of enchancment between the Zen+ and Zen 3 CPU cores could be smaller, however nonetheless important. Zen+ was solely about 1.1x – 1.15x sooner than Zen, best-case.
The Ballad of AM4, Half 2: Hail to the King
When evaluating the worth of an improve versus shopping for an all-new system, it may be useful to think about how a lot efficiency you would purchase in a brand new machine for a similar sum of money. Clients with higher-end GPUs and first-generation Ryzen CPUs are the fortunate winners right here. A Ryzen 5800X, 5800X3D, or 5950X will enhance the efficiency of an existent X370 system excess of the brand new PC you would purchase for a similar value because the chip.
Of us with lower-end playing cards nonetheless have some choices to make. Whereas it’s true that AM5 will launch later this yr, the brand new platform will inevitably carry a premium. DDR5-4800 is rather more costly than DDR4 and the efficiency profit from DDR5-4800 versus DDR4-3600 goes to be marginal in most functions. Chips just like the 5800X3D muddy that comparability extra, for the reason that huge cache can compensate for slower RAM clocks to a level.
Whether or not it is smart to improve a PC at all times comes all the way down to the specifics of 1’s particular person state of affairs, how a lot cash you are attempting to avoid wasting (or spend), and what your individual particular person wants are. What exams like this present is that there’s greater than sufficient life in AM4 to make it a aggressive platform for years to return. A 5 year-old motherboard can nonetheless energy a top-end system. A present AMD person with a Ryzen 7 1800X or beneath can count on significant efficiency enhancements from a CPU swap. When new 4000-series GPUs arrive from Nvidia and AMD launches RDNA3, X370 homeowners with upgraded CPUs will nonetheless be capable of take full benefit of those playing cards.
Kudos to AMD for sending AM4 out on such a excessive be aware. When the corporate introduced it could help AM4 for years again in 2017, it particularly mentioned “Socket AM4” versus “X370 motherboards.” Firms make statements like that to allow them to sundown older merchandise with out breaking such guarantees. On this case, nonetheless, AMD didn’t simply stay as much as the letter of their declare — they fulfilled the spirit of it. The mix of Ryzen 7 5800X + X370 or Ryzen 7 5800X3D + X370 is the perfect improve platform we’ve ever examined.
