A month in the past, AMD introduced the arrival of the Zen three desktop CPU structure. The announcement included new AMD inside benchmarks that implied Intel had misplaced its final desktop efficiency trophy—pure single-threaded efficiency.
Final week, Ars obtained samples of the 2 highest-end fashions within the new CPU lineup—the $800, 16-core/32-thread Ryzen 9 5950X, and the $550 12-core/24-thread Ryzen 9 5900X. And we will affirm most of AMD’s benchmark claims—IPC has improved, together with each single and multi-threaded efficiency, throughout the board, beating Intel soundly on practically all fronts.
The one quibble now we have with AMD’s claims regards energy consumption, not efficiency—and to be truthful, it is virtually definitely not AMD’s fault. The system’s desktop idle energy consumption elevated about 10W—however the improve affected our older Ryzen 9 3900XT CPU, in addition to the 2 new Zen three components. Understanding that, we anticipate the rise comes from the obligatory BIOS improve we needed to carry out on the ROG Crosshair VIII Hero motherboard, somewhat than the brand new CPUs themselves.
Multi-threaded benchmarks
-
Cinebench R20 multi-threaded demonstrates the wholesome IPC bump Zen three provides over Zen 2.
Jim Salter -
Passmark confirms the massive IPC increase we already noticed in Cinebench. The drubbing Intel’s i9-10900Okay takes on this extra general-purpose benchmark is downright embarrassing.
Jim Salter -
For probably the most half, Geekbench for as soon as agrees with Passmark and Cinebench—though it nonetheless tends to flatten the affect of upper core counts.
Jim Salter
Regardless which multi-threaded benchmark you select, you may see a well-recognized relationship between these components—AMD packs on a large efficiency increase from technology to technology, and Intel languishes behind considerably.
As standard, these variations are magnified probably the most in Passmark, and the least in Geekbench—however they’re inconceivable to disregard, and Intel’s more and more aged i9-10900Okay is beginning to look downright embarrassing. Intel might want to pull a reasonably spectacular rabbit out of its hat with its subsequent technology of gaming CPUs if it would not wish to hemorrhage marketshare, as AMD continues to each launch sooner CPUs, and launch new iterations extra steadily.
Single-threaded benchmarks
-
AMD wasn’t kidding about single-threaded efficiency—we pulled record-breaking 630 scores on each the 5950X and 5900X.
Jim Salter -
Passmark single-threaded outcomes additionally blow previous the i9-10900Okay, although by a considerably narrower margin than Cinebench R20 confirmed.
Jim Salter -
Geekbench 5 confirms the single-threaded story informed by Cinebench and Passmark, with a big lead granted to the 2 Zen three CPUs.
Jim Salter
Our single-threaded checks solidly affirm AMD’s claims from the Zen three launch—Intel’s days of dominating single-threaded benchmarks are over, at the very least for now. All three of our single-threaded benchmarks present a wholesome lead for the 2 new Zen three CPUs over Intel’s top-performing single-threaded i9-10900Okay CPU.
As all the time, we warning most individuals to not get too enthusiastic about pure single-threaded outcomes—multi-threaded efficiency will not be equal to single-threaded multiplied by the variety of energetic threads, and vital exercise on different threads will cut back efficiency from the degrees you see right here.
That stated, single-threaded efficiency could be extra necessary in a gaming console setting, the place CPU exercise could be extra tightly managed than it usually is in a desktop PC. Zen three’s massive positive aspects right here will not assist Ps 5 or Xbox Collection X—each of which is able to function CPUs based mostly on the older Zen 2 structure—however we suspect neither Sony nor Microsoft is regretting its resolution to again Staff Purple, all the identical.
Gaming benchmarks
-
3DMark’s Time Spy Excessive CPU check reveals a wholesome efficiency bump for each Zen three CPUs, closely implying they’re the CPUs you may need for 4K gaming.
Jim Salter -
The easier Time Spy CPU check has the i9-10900Okay and the 5950X at a useless warmth, with the 5900X trailing virtually imperceptibly behind. That is in all probability a greater benchmark for 1440P or 1080P gaming.
Jim Salter
3DMark’s extra gaming-specific CPU checks affirm what we already noticed from general-purpose benchmarks—AMD’s Zen three structure is not giving something as much as Intel. Time Spy Excessive—which fashions 4k gaming efficiency and may make the most of extra cores and extra superior CPU directions than Time Spy—delivers a wholesome lead for 5900X and 5950X over each the older 3900XT and Intel’s i9-10900Okay.
The easier, non-Excessive Time Spy benchmark is probably going a greater match for gaming as much as 1440p, and Intel does a lot better there, working a mainly useless warmth with the 5950X and 5900X and barely outperforming the older 3900XT. You are not more likely to see higher gaming efficiency out of the i9-10900Okay than the AMD components, even at decrease resolutions—however should you’re budget-constrained, discover a actually nice deal on the Intel components, and do not care about 4K gaming, it will not harm your framerates.
Energy and warmth
Jim Salter
The place the i9-10900Okay will harm you, sadly, is in warmth technology and energy consumption. The Intel CPU pulls 100W extra energy—and generates 100W extra warmth—than both the previous or new Ryzen 9 CPUs.
Our check outcomes largely affirm AMD’s claims of elevated energy effectivity with Zen three—regardless of having a 200MHz greater clockrate and 25-percent extra cores and threads, Ryzen 9 5950X consumed slightly much less energy beneath load than final technology’s Ryzen 3900XT. We truly noticed barely decrease energy consumption from the 5950X than the smaller 5900X, however we suspect that is a quirk of particular person CPUs somewhat than an overarching distinction between fashions.
We noticed a reasonably vital improve in desktop idle energy consumption, from 53W to 64W—however the improve would not look like a results of the CPUs themselves. We would have liked to flash our ROG Crosshair VIII Hero motherboard with a brand-new BIOS that wasn’t but publicly obtainable so as to help the 2 new CPUs. After noticing the rise in desktop idle energy consumption, we swapped again to the Ryzen 9 3900XT and noticed a good bigger improve in energy draw on that processor.
We suspect that the rise in idle energy consumption might be addressed in future publicly obtainable BIOS variations. We additionally suspect that only a few of the individuals who need a Ryzen 9 or Core i9 CPU are going to let the distinction between 53W and 64W hassle them a lot.
Conclusions
AMD’s new desktop processor lineup is a reasonably simple story—the corporate promised greater multi-threaded and single-threaded efficiency and not using a corresponding sacrifice in effectivity after which delivered on these guarantees.
Starting with the 3900XT, AMD determined to not present OEM coolers with Ryzen 9 components—and the corporate caught with that call with the brand new 5900X and 5950X. Though some readers have complained concerning the lack right here, AMD justifies it with claims that knowledge reveals only a few prospects at this processor degree follow the OEM cooler anyway. We see no purpose to doubt AMD there.
With the discharge of those new Zen three processors, Intel followers lose their final massive bragging proper—single-threaded efficiency. Intel is now behind AMD on efficiency, energy effectivity, and even launch depend on desktop CPUs—its final gaming CPU was the i9-10900Okay, launched in Could. AMD is now two releases forward, with the 3900X and 3900XT in July, and 5900X and 5950X at present.
In the meantime, Intel’s next-gen Rocket Lake is not anticipated till someday in 2021—and it is broadly expected to stay on Intel’s 14nm course of, though utilizing options backported from the 10nm Sunny Cove structure. We’re additionally anticipating Rocket Lake to high out at solely eight cores, in comparison with Comet Lake’s ten.
Intel’s latest Tiger Lake cell CPUs are nice performers regardless of their equally low core depend, and it is doable that Rocket Lake will get pleasure from related success subsequent yr—however we aren’t betting on it. We suspect that Intel’s tough instances on the desktop aren’t going to be over any time quickly.
The nice
- 200MHz greater clockrate in 5950X over 3900XT
- Increased IPC to associate with the upper clockrates
- Important single-threaded efficiency enchancment
- Largely unchanged energy profiles, effectively under Intel’s
- Higher Time Spy Excessive CPU check outcomes than Intel’s
- Supported on B550 motherboards with BIOS improve
The dangerous
- “Solely” equal Time Spy (non-Excessive) CPU outcomes with Core i9-10900Okay
- Will probably nonetheless be tougher to search out in pre-built OEM PCs
The ugly
- Intel’s present place on the desktop
