AMD’s Ryzen 9 3950X lands in November (after it was delayed), but beforeit hits the street some interesting fresh details have been spilled on the CPU and its overclocking potential.

 

This comes from hardware vendor Gigabyte which made an overclocking guide for its Aorus X570 available online, detailing the firm’s results when juicing up the Ryzen 3rd-gen processor.

We already knew that the 3950X boosts up to 4.7GHz – or at least that’s the official word from AMD – but that’s over two cores, Gigabyte notes in the documentation (and potentially the wrong – ie not active – cores, another bugbear with Ryzen 3000 CPUs which has been highlighted recently).

 

So how fast can the incoming flagship chip be pushed over all its 16-cores with overclocking? As fast as 4.3GHz, it would seem, given Gigabyte’s setup which utilized an EK-KIT P360 water-cooling solution and the Aorus X570 Master motherboard. That’s a good chunk faster than the base clock speed of 3.3GHz, of course.

 

The firm found the 3950X reached a stable 4.3GHz using around 1.4V, and the overclock meant an increase in Cinebench R15 multi-threaded from 3,932 at stock to 4,384 overclocked, an 11% boost. Not too shabby, indeed.

Thermal marvels?

Gigabyte further observed that the temperatures witnessed during the overclocking session were “similar [to] what we were getting last year using a Ryzen 7 2700X”. So for this 16-core behemoth to be pushed across all its many cores and be performing in similar thermal terms to a 2nd-gen 8-core model is, well, quite impressive.

 

Also remember that the Ryzen 9 3900X recorded a Cinebench R15 result of 3,097 when we reviewed the chip, so that makes the incoming flagship something like 27% faster at stock speeds.

 

Even more telling is the comparison between the 3950X and an Intel Core i9-9900K, with the latter hitting 1,873 – so AMD’s chip is more than twice as fast.

 

Of course, this is only one benchmark, and as such hardly the whole performance picture – but still, it would seem that things are shaping up very nicely for the Ryzen 9 3950X, and it could help to hammer home the big gap AMD continues to open up in sales over Intel (at least in the desktop market).

 

Although how easy it will be to buy one of the things may be another matter entirely, so let’s hope the launch delay is about suitably ensuring demand doesn’t once again completely outstrip supply (as with the 3900X).

Overclocked Ryzen 9 3950X outperforms 24-core 2970WX in Cinebench

It beats Intel's i9-9980XE, too

 

Why it matters: From six cores through twelve, Ryzen’s third iteration kills it in multicore benchmarks, and we expected nothing less from the upcoming 16-core 3950X. But according to an accidentally published overclocking manual from Gigabyte, performance is even better than anticipated and an overclocked 3950X can surpass all of Intel’s HEDT processors and is beaten only by AMD’s 32-core Threadripper.

Gigabyte’s engineers were able to consistently overclock the Ryzen 9 3950X to 4.3 GHz on their X570 Aorus Master motherboard (pictured above) using EKWB’s custom waterloop kit containing a 360mm radiator. The chip they used for benchmarking was running at 1.416 V with an x43 multiplier applied to a 99.98 MHz bus. Under a Prime95 workload, Die 1 had an average temperature of 97 C and a max of 101 C, and Die 2 averaged 93 C and spiked to 97 C. Not for the faint of heart, but not unmanageable.

 

At 1.452 V they were able to get one specific chip to run at 4.4 GHz, but they suggest that 4.3 GHz is the general limit for stability. In TechSpot’s own testing, both the 3900X and 3700X maxed out at 4.3 GHz on a 360mm AIO.

 

Threadripper results are from TechSpot's reviews, Ryzen results courtesy of Gigabyte.

 

And finally, to the results. The 3950X simply obliterates AMD’s current 16-core monster, the Threadripper 2950X, scoring 24% higher. It falls a mere 10% behind the 24-core 2970WX. Overclocked to 4.3 GHz results are even more impressive as it can improve its score by 11%, pushing 1% past the 2790WX.

 

According to online results for the 18-core i9-9980XE, that chip can only achieve a ~3700 score at stock and ~4200 overclocked, both of which are about 200 points behind the 3950X when similarly configured.

 

Surely, the soon to be released i9-10980XE might outdo the 3950X, but at $230 more than the 3950X’s $749, Ryzen will probably be the value winner. We’ll know soon when both the 3950X and Intel’s Cascade Lake-X launch in November.
