The $ 449/£ 429 Ryzen 7 5800X3D is one thing a bit totally different from AMD, a processor that exists to show the facility of the agency’s 3D V-Cache design for its upcoming Ryzen CPUs and struggle off Intel’s 12900KS for the title of ‘quickest gaming processor’. It is also one thing of a final hurricane for the surprisingly long-lived AM4 platform, which debuted again in 2017 and outlasted half a dozen Intel generations as Ryzen CPUs improved in leaps and bounds.
So what precisely is a 3D V-Cache anyway? Let’s begin with the fundamentals. You may consider a processor’s cache as a spot to retailer information it is at the moment engaged on – a bit like RAM, however as a result of it is contained in the CPU it is an order of magnitude sooner to entry and an order of magnitude smaller by way of the quantity of information it could possibly retailer. Trendy processors usually use three ranges of cache – L1, L2, L3 – with L1 cache being the quickest to entry however the smallest, L2 being slower however bigger, and L3 being slower and bigger once more. It is this third degree of cache that AMD has modified, transferring from a conventional 2D design to a 3D design, a stack of cache that takes up extra vertical area. This enables for far more information to be saved contained in the CPU without delay, thus rising the probabilities that the information wanted is already inside and dashing up any subsequent processing.
AMD is slated to make use of this expertise for its future Zen 4 processors, however within the right here and now it is simply this one particular 5800X3D, an upgraded model of the Ryzen 7 5800X that launched again in 2020. In comparison with the 5800X, the 5800X3D trades a little bit of frequency and a few overclocking controls for a considerably bigger 96MB L3 cache – triple the dimensions of the 5800X’s.
|CPU design||Increase||Base||L3 cache||TDP||RRP|
|Ryzen 5950X||Zen 3 16C / 32T||4.9GHz||3.4GHz||64MB||105W||$ 799|
|Ryzen 5900X||Zen 3 12C / 24T||4.8GHz||3.7GHz||64MB||105W||$ 549|
|Ryzen 5800X3D||Zen 3 8C / 16T||4.5GHz||3.4GHz||96MB||105W||$ 449|
|Ryzen 5800X||Zen 3 8C / 16T||4.7GHz||3.8GHz||32MB||105W||$ 449|
|Ryzen 5700G||Zen 3 8C / 16T||4.6GHz||3.8GHz||16MB||65W||$ 359|
|Ryzen 5600X||Zen 3 6C / 12T||4.6GHz||3.7GHz||32MB||65W||$ 299|
|Ryzen 5600G||Zen 3 6C / 12T||4.4GHz||3.9GHz||16MB||65W||$ 259|
Earlier than we get into the primary take a look at outcomes, let’s briefly cowl the rig we’re utilizing. For the AMD facet, we’re utilizing an Asus ROG Crosshair 8 Hero, whereas Eleventh-gen Intel will get an Asus ROG Maximus Z590 Hero and Twelfth-gen will get the Asus ROG Z690 Maximus Hero – all high-end boards for his or her respective platforms. DDR4 motherboards used G.Ability 3600MT / s CL16 reminiscence, whereas Twelfth-gen Intel acquired the good thing about sooner however higher-latency Corsair 5200MT / s CL38 RAM.
The AMD and Eleventh-gen Intel CPUs have been cooled with an Eisbaer Aurora 240mm AiO, whereas the Twelfth-gen testing was carried out with an Asus ROG Ryujin 2 360mm AiO. (And to reply the apparent query: 240mm and 360mm AiOs tends to supply equal efficiency primarily based on our testing – particularly for an open air take a look at bench in cool (21C) ambient situations. The one distinction tends to be fan pace, which is increased on the 240mm than the 360mm.) Our rig was accomplished with a 1000W Corsair RM1000x energy provide from Infinite Computing.
With the intention to scale back run-to-run variance and guarantee we’re CPU-limited as a lot as doable, we’re utilizing the Asus ROG Strix 3090 OC Version. It is a huge three-slot, triple-fan design that retains the cardboard surprisingly cool and quiet.
One of many largest questions over the 5800X3D is strictly the place that upgraded cache will are available in helpful – as a result of if a sport or different utility does not match a particular efficiency profile, it could see no efficiency benefit in any respect operating on the 5800X3D – and certainly , it could even run worse as a result of clock pace that AMD has sacrificed to make the design work.
To seek out out, we have examined the 5800X3D in a variety of content material creation and gaming situations – towards the unique 5800X and plenty of different current AMD and Intel processors. We’re hoping to see some huge efficiency will increase, particularly in video video games, however we’ll begin with a few fast content material creation benchmarks: a Cinebench R20 3D render and a Handbrake video transcode.
|CB R20 1T||CB R20 MT||HB h.264||HB HEVC||HEVC Energy Use|
|Core i9 12900K||760||10416||70.82fps||29.26fps||373W|
|Core i7 12700K||729||8683||57.64fps||25.67fps||318W|
|Core i5 12600K||716||6598||44.27fps||19.99fps||223W|
|Core i5 12400F||652||4736||31.77fps||14.70fps||190W|
|Core i9 11900K||588||5902||41.01fps||18.46fps||321W|
|Core i5 11600K||541||4086||29.00fps||13.12fps||250W|
|Ryzen 9 5950X||637||10165||70.28fps||30.14fps||237W|
|Ryzen 7 5800X3D||546||5746||42.71fps||19.10fps||221W|
|Ryzen 7 5800X||596||6118||44.18fps||19.50fps||229W|
|Ryzen 5 5600X||601||4502||31.75fps||14.43fps||160W|
Neither content material creation result’s significantly spectacular for the 5800X3D, which outperforms the 5600X and Intel 12400F however falls behind its erstwhile rivals just like the 12900K, 12700K and 5800X (the latter by between two to 6 p.c). This is not a large shock – neither job would logically profit from having a bigger cache, so that you solely see the impact of the brand new CPU’s lowered core clocks in comparison with the usual 5800X. Nonetheless, the outcomes aren’t disastrous both; that is nonetheless a wonderfully succesful CPU for these duties that handily outperforms prior generations, simply not a class-leading one.
With these out of the best way, let’s transfer onto the enjoyable stuff: testing how the 5800X3D performs in a variety of video games. Click on the fast hyperlinks beneath to maneuver onto the titles you are most excited by, or hit the ‘subsequent web page’ button to take all of it in!
