If you snap on this article , you have belike learn reviews or watched videos about AMD ’s latest CPU release , the Ryzen 7 7800X3D. Typically , we would have promote our review out alongside the masses at launch . However , we needed to take a beat with this one .
As we await at our goal for this reexamination – to give you the best box - to - build judgement that we could , it mean that we would involve to be late to the company . Why ? We experienced some leftover stability issues that we want to ensure were not present with Day One drivers and BIOS . After retesting everything on multiple weapons platform , we can confidently describe to you that what we experienced was anomalous , but we require to be careful !
Hopefully , that did n’t dash you off , because the Ryzen 7 7800X3D is an amazing opus of computer hardware ! We had a intuition it would be . After all , in our early coverage of theRyzen 7000 Series , we manoeuvre out that the good value - for - dollar bill central processor in the Ryzen 7000 Series pot was theRyzen 7700X. While our opinion hold mostly , the Ryzen 7 7800X3D made us ask ourselves some serious enquiry .

Productivity performance is serviceable , but unremarkable
The Ryzen 7 7800X3Dis one of three 3D V - cache equipped Zen 4 central processor , but it , like this review , has arrived fashionably tardily to the party started by the Ryzen 9 7900X3D and Ryzen 9 7950X3D at the end of February . And the 7800X3D has made quite the entryway .
While it ’s poise to be “ the honest gambling CPU ” within its class , a multitude of third company trial – including our own – show that the 7800X3D is an absolute problem shaver – upsetting the whole CPU hierarchy in gaming performance by matching or beating the performance of both Intel ’s Core i9 - 13900 K and AMD ’s 7950X3D.

This is all a piece confusing , so we ’re snuff it to need to dive into some exhibition on 3D quintet - memory cache and how these CPUs work first … and there is go to be a snatch of it .
Cache is (Still) Gaming’s Kingmaker
We covered some of these details in ourreview of the Ryzen 9 7950X3D , but it is deserving revisit .
AMD ’s 3D V - stash engineering conduct those thicc n ’ beefy Zen 4 core that we know and have sex , slims them down ever so slightly , and stack an extra layer of L3 hoard on top of the chiplet without increase the overall vertical ( or Z- ) acme of the CPU . This design permit the CPU die to have unmediated access to the stash , providing a faster memory board resource than your organization Aries .
In game scenario , this buff up stash help the CPU when rapid access to random data point is essential . Because role player - driven action are a random process , the 3D V - cache assists your CPU by recalling texture , animation , game physics , character reference placement , and more . While organisation cram assists with this as well , the latency is much low because instruction do n’t have to travel far . The ending result is good overall gaming carrying out .

( you may ascertain AMD ’s equipment failure of 3D V - cache technologyhereif you are interested in learning more . )
This engineering science has been largely successful , with the Ryzen 7 5800X3D serve as the parvenu that started it all last class . tight forward to the present and one product contemporaries after , and we now have three current propagation Ryzen CPUs swim in cache .
But this is where things divert a bit .
Graphic: Damien Gula / Gizmodo
If you seem at the intent of the Ryzen 9 C.P.U. , the 7900 and 7950 ( in their X , non - X , and X3D variants ) each has a core complex dice ( CCD ) made up of , as the name implies , two burden complexes ( CCX ) . While the X3D processors in the Ryzen 9 house also have two gist complexes , only one CCX is equipped with the 3D 5 - cache .
As divvy up before , AMD ’s official word is that they did not see a pregnant enough uplift in performance in the Ryzen 9 CPUs to excuse the extra toll of equipping the second CCX with 3D 5 - cache . Instead , they would bank on Windows processes like Game Bar to whitelist games to apply 5 - cache equipped cores while parking the others .
This system allows the V - cache outfit CCX to shine in gaming scenarios while the heftier , high clocked CCX does the dense lifting in productiveness . It ’s a revolutionary system of rules , but in day - to - day operations , it is rather discrepant .

The Ryzen 7 7800X3D , however , only has a single CCX . It does not need to be told which CCX to prioritize and which one to park because there is no division . The 7800X3D is just steeped in that sweet , sweet cache , babe !
Enough with the yak , allow ’s get deep into the particular .
Similar AMD Hood, Slightly Different AMD Hardware
The 7800X3Dbears the Ryzen 7 name – a category delineate by its 8 - centre , 16 - thread ( 8C/16 MT ) makeup . While gist count is the same as its Ryzen 7 family line , the AMD Ryzen 7 7800X3D has a slimly slower base and hike up clock than the Ryzen 7 7700X. Where the 7700X has a understructure clock speed of 4.5 GHz and encourage speeds up to 5.4 GHz , the 7800X3D trots slimly behind with a stem clock speed of 4.2 GHz and max boost speeds up to 5.0 GHz .
However , when it comes to baron draw , the 7800X3D does compact on 15W on top of the 7700X ’s 105W TDP for a modest 120W. This does correspond the TDP of the other X3D CPUs , but we will see what the 7800X3D does with that major power . You might be surprised .
AMD Ryzen 7 7800X3DBenchmark Breakdown
In our productiveness charts , you are going to see data point from the integral Ryzen 7000 Series stack as well as Intel ’s 13th GenerationCore i5 - 13600KandCore i9 - 13900K. However , in gaming , we want to narrow the athletic field to the current high end contenders . Since this is a battle for the crown , we ’ll be lay the Ryzen 7 7800X3D against theCore i9 - 13900KandRyzen 9 7950X3D.
All of this data was take in employ a similar examination environment and methodology to keep things as clean-living as potential , but , as always , your mileage may diverge . The turn you are about to see lay out box - to - build public presentation with piddling - to - no tweaks and consistent setting . The only advantage we give each platform was that we enable an AMD EXPO of XMP profile for low storage latency and fastness .

Productivity Is Not the Sweet Spot, ButThe 7800X3DStill Does the Work
We ran a cortege of software benchmark to highlight individual and multi train of thought performance in scenarios designed to prove how each CPU perform under various computational freight .
In our productivity tests , the Ryzen 7 7800X3D perform adequately , but the extra 5 - memory cache does not really make it stand out in the crowd . In some respects , it really falls somewhat behind the Ryzen 5 7600 .
Here is what we found :
Geekbench 5 gives us a picture of single thread central processor performance for every day process such as image and text compression , web navigation , car learning , and .PDF rendering . In this bench mark , the Ryzen 7 7800X3Dunderperformed when compare to its Ryzen 7 counterparts . When front at the numbers across the card , the 7800X3D pace closer to the Core i5 - 13600 K than its own class of CPU .
In multi - core performance , the 7800X3Dcatches up to its Ryzen 7 kinsperson while falling slightly behind the 7700X. Since the 7700X leads the 7800X3D in overall absolute frequency , this is unsurprising . Like the 7950X3D , this could be a scenario where the excess cache just does n’t give any benefit . That being said , it was salutary to see the 7800X3D grab up with its class !
We see a like story in Handbrake :
While fork over a 4 1000 video down to 1080p30 , the 7800X3D interpret slightly faster than the 7700X while hang back behind the 7900 . However , it is worth noting that this test was one that caused our testing bench to crash on multiple occasions . We ’ll talk a little bit more about that when we look at thermal performance .
In Blender , the 7800X3Dlagged behind the 7700 while render an image of a shiny reddish BMW . This picture took the 7800X3D just over two minutes to try , lay it 3 mo behind the Ryzen 7 7700 while set considerable length between itself and the Ryzen 5 folk . Again , this is a situation where we do n’t see the Little Phoebe - hoard help processor operation .
Like the Ryzen 9 7950X3D , we did not see an overall benefit or uplift in performance in our productiveness bench mark . That does n’t mean that the 7800X3D ca n’t perform at serviceable spirit level , it just means that the X3D chips are not the central processing unit for these workloads .
The Book of Job for the X3D CPUs , however , is play .
Simplicity Beats Complexity in Gaming
unearthly question : are you familiar with Occam ’s razor ?
It ’s a problem - solving rule that roughly translates into English as this : “ entities must not be multiplied beyond necessity . ” Or , to reduce it even further : “ the simple explanation is normally the best one . ”
When translating that to computers , we can take it to mean “ fewer complexities means few opportunities for matter to go wrong . ”
Keep that in psyche as we take a look at the act :
In most of our play scenarios at 1080p , the Ryzen 7 7800X3Deither match or led the Intel Core i9 - 13900 K and AMD ’s own flagship play CPU , the Ryzen 9 7950X3D. While some of these turn are within too faithful of a margin to declare a succeeder , we saw some meaning outlier where we see a performance delta of ~7 % to ~20 % between the Core i9 and the 7800X3D as well as deltas separating it and the 7950X3D up to ~15 % .
Now , there is more to this story … and this data point could age like fine Milk River . So , why give it ?
rent ’s go back to Occam ’s razor for a 2nd ; I believe we see this principle at work in our gaming benchmarks of the 7800X3D when compare to the 7950X3D at the time of writing this review .
Remember : the 7950X3D is progress with two dissimilar core complexes – one with the V - cache and one without . That CPU is hooked on instructions from Windows to part some cores while prioritise others . In AMD ’s own word , they did not put V - cache on both complex cores of the Ryzen 9 because they did n’t see pronounced improvement in carrying into action with more than one core complex equipped .
In one sense , they followed Occam ’s razer – they did not “ multiply beyond requirement , ” at least , one the hardware end of things . They did , however , multiply the instructions needed to leverage the engineering . And that is where we are seeing the difference .
correctly now , we ’re see the 7800X3D take the performance principal in gaming because it ’s kept things simple . The 7800X3D has a single core group composite fit out with 3D V - hoard . It is n’t take care for instructions for which core complex to utilize because it only has one – it literally ca n’t go anywhere else with gaming processes !
And it handle those gaming processes like the absolute monster it is .
AMD Ryzen 7 7800X3DEnergy Efficiency and Thermal Performance
When we watch the initial proclamation for the Ryzen 7000X3D central processing unit , one of the points that we noticed like a shot on the product infographic was the TDP for the X3D CPUs in copulation to the closest counterpart .
I have a go at it that I am not the first someone to point this out , but I can not hyperbolise what these charts show . When it comes to powerfulness draw and efficiency , the 7800X3D is like a loyal handshake between cost - cognizance and environmental - consciousness . The 7800X3D sip office like wattage is coffee that ’s just too hot at the moment while plowing through its process with enough succus to get the job done .
If you refer back to our gaming performance charts , you will see the 7800X3D suck less electric power for adequate or well performance than the 7950X3D. Even with a higher overall TDP than its fellow Ryzen 7 , the 7700X , the 7800X3D shows its authorisation in power efficiency . When we look across the aisle , when look at the Core i9 - 13900 K , the divergence is just astronomical .
When it comes to thermal performance , however , the picture is a bit different .
Within the Ryzen 7000 Series , we have been used to take in some higher number when it comes to thermal performance . We were n’t awful surprised to see the thermic data we collected , but the Ryzen 7 7800X3D did see higher temperature across the plank in both gaming and productivity psychometric test .
However , we observe earlier that we had some stability issues while carry our encoding bench mark with HandBrake . During these tests , we catch our mainframe hit temperatures up to 93C while under load . Keep in mind , this was while being actively cool down by a real mainframe cooler . With how sensitive the 3D V - hoard can be , I wonder if we pushed it too far thermally .
A Pro-Cache Conclusion
If the welfare to gaming performance and the utter dominance of the applied science in AMD ’s preceding two central processor generations has n’t spelled it out , 3D V - cache is here to stay . The Ryzen 7 7800X3Dshows dominance within 1080p gaming and incredible power efficiency across gaming and productivity workloads .
So , at $ 449 USD , is the Ryzen 7 7800X3D deserving it ?
Like always , that answer calculate on what you desire to do with it .
This is n’t a frightening mainframe for productivity and 24-hour interval - to - day tasks , but it just does n’t shine as brilliantly outside of play . For $ 100 less , the Ryzen 7700X is still , in my legal opinion , one of the more well - rounded central processor in the merchandise stack , offer upstanding public presentation in play and productivity .
However , when you look at the power efficiency and gaming public presentation of the 7800X3D , this central processor is unparalleled in its value proposition for gamers , especially when you look at its retail cost versus its challenger . At launching , the 7800X3D is around $ 100 USD less than Intel ’s flagship , the Core i9 - 13900 K , and $ 350 USD less than AMD ’s Ryzen 9 7950X3D.
When evaluating the retail toll and the gambling functioning with each of these central processor , the Ryzen 7 7800X3Dupsets the current processor hierarchy to become , without contest , the best time value and performer .
