For our inventory configurations, we examined the Core i9-11900K with each ABT enabled and disabled. As you’ll be able to see, the delta between those two settings lands at 2% for 1080p when measured over our complete check suite, that means the variation in gaming normally is not going to be noticeable. Then again, a couple of heavily-threaded titles will receive advantages. We see a little extra gaming uplift with our overclocked setup, amounting to a extra considerable 5.5% build up over the non-ABT configuration.

The 11900K has taken a large step ahead over the 10900K in gaming, bringing Intel into nearer festival with AMD and narrowing the delta between the highest-end chips. The Core i9-11900K is extra aggressive after overclocking, however the Ryzen 9 5900X nonetheless leads in each inventory and overclocked configurations at 1080p, giving AMD the bragging rights. Then again, that image adjustments after we take a look at 1440p, the place the 11900K with ABT necessarily ties the overclocked 5900X, and the Core i9-11900K takes a 2% lead after overclocking.

Flipping thru the person video games displays that the chief can alternate relatively dramatically, with other titles responding higher to both Intel or AMD. Our geometric imply of all the check suite is helping clean that out to one digestible quantity, however keep in mind – the quicker chip may range in line with the sport you play.

Winner: AMD

General, the two chips are very carefully matched in our general gaming exams, as efficiency will range in large part in line with the kind of identify you might be taking part in. Something is obvious – Intel’s chip does no longer cement it because the transparent chief in gaming, which Intel would wish to justify the 11900K’s price ticket. When paired with lesser GPUs or when gaming at upper resolutions, the efficiency deltas between the two chips will shrink to the just about imperceptible vary, however the Ryzen 9 5900X does take the identify general at 1080p, in all probability leaving a little extra headroom for long run GPU upgrades.

We will be able to boil down productiveness application efficiency into two vast classes: single- and multi-threaded. The primary slide has a geometrical imply of efficiency in different of our single-threaded exams, and the Core i9-11900K takes a 6.7% lead over the Ryzen 9 5900X.

You can realize that enticing the ABT spice up in reality leads to somewhat decrease single-threaded efficiency. As we see with AMD’s auto-overclocking Precision Spice up Overdrive (PBO), that is not unusual with auto-tuning approaches which can be designed to spice up efficiency in multi-threaded paintings. The 11900K additionally has slower efficiency in single-threaded paintings with a 5.2 GHz overclock, however that is as a result of our overclock does not fit the 11900K’s 5.3 GHz spice up that you can get at inventory settings.

Regardless, the Core i9-11900K has extremely snappy efficiency in single-threaded duties, just like the LAME and FLAC encoders, and the Cinebench 23 and POV-Ray renderers. We additionally see very snappy efficiency in internet browsers, which have a tendency to be flippantly threaded, and a bruising efficiency merit within the single-threaded AVX-512-enabled y-cruncher.

General, the 11900K is spectacular in single-threaded paintings, however it is too unhealthy the chip greenbacks the rage of single-threaded prowess equating without delay to awesome gaming efficiency.

The primary slide brings the efficiency worth of the Ryzen 9 5900X’s upper core counts into transparent focal point. This geometric imply of our threaded application workload effects displays that the 5900X’s four core merit equates to a whopping 27% merit over the 11900K in threaded efficiency at inventory settings, and an similarly spectacular 26% merit between the overclocked configurations.

The 5900X’s merit is clear throughout just about the entire gamut of our threaded benchmarks, with compression and decompression experiencing super uplift at the energy of the 5900X’s 12 cores. The 5900X additionally dominates in rendering workloads, like our quite a lot of Blender, C-Ray ray tracing, Cinebench R23, and v-ray rendering exams.

Intel does generally tend to supply higher efficiency in AVX-enabled workloads, granting the 11900K a resounding step ahead over the 10900K within the AVX-512-enabled y-cruncher. Then again, Intel’s AVX prowess does not equate to important wins in additional practical and commonplace AVX code, just like the x264 and x265 HandBrake exams that pass to the 5900X in a resounding style. The 5900X may be awesome in our LLVM compilation and NAMD simulation code exams.

Rocket Lake does submit drastic enhancements in AES and SHA3 workloads, which comes by way of explicit optimizations within the Cypress Cove structure for most of these workloads. However identical to we see with AVX-512, those are reasonably area of interest use circumstances within the grander scheme of standard desktop PC programs.

Winner: AMD

It is a tall order to invite the eight-core Core i9-11900K to check the 12-core Ryzen 9 5900X in threaded workloads, so we anticipated to look the Ryzen type simply beat Rocket Lake in threaded programs. And that’s the reason precisely what took place. Intel’s Core i9-11900K suffers by the hands of its decreased core rely, or even the previous-gen ten-core Core i9-10900K even beats it in different workloads. With a 27% merit in threaded workloads, the Ryzen 9 5900X simply will get the nod for threaded productiveness programs.

Conversely, the Core i9-11900K is spectacular in single-threaded programs with a 6.7% lead over the 5900X, however that is predicated upon the working gadget being reasonably ‘quiet’ without a further duties working within the background. To not point out that the everyday PC use case comes to a number of programs operating at the same time as. For the reason that maximum desktop PC use comes to some stage of multi-tasking, the Ryzen 9 5900X’s further core counts lead to extra tangible efficiency beneficial properties in real-world utilization fashions, giving AMD the win on this class. 

Ryzen 9 5900X vs Core i9-11900K Overclocking

We’ve lengthy since reached the land of diminishing returns for overclocking the highest-end chips from each AMD and Intel. That is in large part as a result of each firms are engaged in a heated dogfight for efficiency superiority at the excessive finish, such a lot of the overclocking frequency headroom is rolled into usual inventory efficiency, leaving little to be had for tuners. You can in finding higher overclocking beneficial properties with the downstream fashions.

Intel does have the benefit of upper possible clock charges, even though, particularly in the event you focal point on overclocking a couple of cores as an alternative of the usual all-core overclock. Intel additionally exposes a wealth of tunable parameters with its Rocket Lake chips. That incorporates new overclocking offsets, like a separate AVX-512 offset and the facility to set voltage guardbands for the other flavors of AVX. Intel additionally added an method to utterly disable AVX improve, even though that function is essentially geared for pro overclockers. Rocket additionally helps per-core frequency and hyper-threading regulate (permit/disable) to lend a hand eke out extra overclocking headroom.

Intel added improve for real-time reminiscence frequency changes, even though motherboard improve will range via type and dealer. This option means that you can shift from, say, DDR4-2933 to DDR4-3200 from inside of Home windows 10 with out rebooting. Intel additionally continues to improve its current mechanism for are living reminiscence timing changes from inside the working gadget, giving customers a plethora of on-the-fly reminiscence overclocking choices.

Intel has lengthy locked overclocking to its dear Okay-series fashions, whilst AMD freely permits overclocking with all SKUs on nearly any platform. Then again, we see indicators of a few development right here from Intel, because it has now enabled reminiscence overclocking on its B560 and H570 chipsets around the board. That stated, Intel’s new paradigm of Tools 1 and Tools 2 modes does cut back the price of reminiscence overclocking, which you’ll be able to learn extra about in our assessment.  

AMD’s Ryzen 5000 chips include leading edge spice up generation that in large part consumes many of the to be had frequency headroom, in order we see with Intel’s flagship, there’s valuable little room for bleeding-edge clock charges. In truth, all-core overclocking with AMD’s chips is lackluster; you might be steadily the usage of its auto-overclocking function that enhances multi-threaded efficiency.

Winner: Intel

Intel’s Core i9-11900K does not have as a lot overclocking frequency headroom as its predecessors, but it surely nonetheless has the best possible frequencies, in particular in the event you focal point on per-core overclocking. Intel does rate a top class for its overclocking options, but it surely gives a wealth of tunable parameters for fanatics.

Energy intake and warmth pass hand in hand, and Intel’s Core i9-11900K consumes extra continual than any of the corporate’s preceding mainstream processors. In truth, we recorded a height of 295W all the way through an AVX-512 Prime95 check.

Whilst the Prime95 tension check is not actually indicative of what you can see all the way through common use, we recorded a lot upper continual draw around the board in all the programs defined above. That leads to the eight-core11900K eating no longer most effective extra continual than the previous-gen ten-core 10900K, which was once already a power-hungry chip, but it surely additionally consumes excess of the competing Ryzen 9 5900X.

It is spectacular that AMD has wrung such a lot efficiency out of its 12-core Ryzen 9 5900X, but nonetheless manages to devour a ways much less continual than Intel’s eight-core type. That receive advantages comes by way of TSMC’s 7nm procedure, whilst Intel’s 14nm procedure has clearly reached the top of the street with regards to absolute efficiency and potency.

In truth, a handy guide a rough take a look at the renders-per-day charts unearths that AMD’s Ryzen 9 5900X is in every other league with regards to continual potency — you get way more efficiency in keeping with watt ate up, which leads to decrease continual intake and warmth technology.

Winner: AMD

AMD wins this around simply with decrease continual intake, upper potency, and no more thermal output. Intel has became the facility dial as much as the intense to stick aggressive with AMD’s 7nm Ryzen 5000 chips, and consequently, the Core i9-11900K is power-hungry and generates an amazing quantity of warmth for an eight-core chip. Neither processor comes with a bundled cooler, however you can wish to price range in a beefier type to care for the 11900K’s prodigious continual draw and thermal technology. 

Core i9-11900K vs Ryzen 9 5900X Pricing and Worth Proposition

If we suppose that you’ll be able to in finding each the Ryzen 9 5900X and Core i9-11900K just about really useful pricing, Intel actually ignored the mark with the 11900K’s prompt pricing. Because the announcing is going, there aren’t any unhealthy merchandise, simply unhealthy pricing. And the Core i9-11900K for sure has unhealthy pricing.

For avid gamers, the Core i9-11900K must display a extra considerable merit to justify its price ticket and tool intake — the efficiency deltas are so narrow you most likely would not realize a lot distinction with current-gen mainstream GPUs, particularly at heightened constancy settings. That makes it laborious to justify the Core i9-11900K’s $539 price ticket.

AMD’s $549 Ryzen 9 5900X gives awesome efficiency in day by day programs, in particular in closely threaded paintings. Moreover, the 5900X’s further cores will equate to raised efficiency in multitasking situations, to not point out simultaneous gaming and streaming. General, the Ryzen 9 5900X gives a lot more worth for $45 in keeping with core than the 11900K’s $67-per-core asking worth.

Then again, availability reigns perfect in those occasions of a world chip scarcity, and whilst Intel’s Core i9-11900K arrived with cast availability, it’s these days bought out at maximum primary outlets. The location seems way more dire with the Ryzen 9 5900X, even though, which has suffered from deficient availability and intense worth gouging for a number of months.

Winner: AMD

Assuming you’ll be able to in finding both of those chips at just about sane pricing, the Ryzen 9 5900X gives way more worth for avid gamers and creatives alike, in large part because of its cast mix of efficiency in gaming, single- and multi-threaded paintings.

The Ryzen 9 5900X wins four out of five classes, whilst additionally scoring a tie within the options segment. Our CPU faceoff finally ends up being a five to two win in choose of the Ryzen 9 5900X, that means that the selection will have to be relatively transparent for many fanatics. 

The Ryzen 9 5900X in the end wins at the energy of its higher mix of gaming and application efficiency, to not point out that it comes with a lot decrease continual intake that in the end leads to a cooler and quieter gadget. And that’s the reason in spite of it coming with four extra cores than the 11900K.

AMD’s a hit system has consisted of extra cores, a more recent structure, and a denser 7nm node, however Intel introduced the Core i9-11900K on an older, less-efficient 14nm node with fewer cores. Because of this, Intel tried to offset the decreased core rely via dialing continual intake to the intense to maximise efficiency. That leads to a lot upper continual intake and larger warmth, so you can desire a very succesful cooler and powerful motherboard to release the most productive of the 11900K, which provides value.

The Core i9-11900K is spectacular in gaming and lightly-threaded paintings, but it surely trails the similarly-priced Ryzen 9 5900X via massive margins in threaded programs and does not cement itself neatly sufficient as a gaming chief to justify its top class price ticket. That stated, the 11900K and 5900X are so shut in gaming that almost all would possibly not realize the variation, particularly with mainstream GPUs and better resolutions. If you want built-in graphics, the Core i9-11900K is your glaring selection. 

After all, that is all only if you’ll be able to in finding both of those chips at just about prompt pricing. Like different chipmakers, AMD has struggled with chip shortages for a number of months, resulting in deficient availability and value gouging, and it does not appear to be the placement will make stronger enormously within the close to time period. Intel has looked as if it would handle a greater provide of its chips, and Rocket Lake is these days to be had for a lot more cheap pricing than the Ryzen processors. That implies the chip that you’ll be able to in finding at cheap pricing might win via default.
