MSI Kombo Strike For Ryzen 7 5800X3D Reveals Blended Outcomes In Early Benchmarks


AMD Ryzen 7 5800X3D
The Ryzen 7 5800X3D is an attractive chip for avid gamers as a result of AMD stacked on a pile of 3D V-cache, successfully vastly growing the quantity of L3 cache (to 96MB complete). Extra L3 cache can have a measurable impression in gaming, as we confirmed in our Ryzen 7 5800X3D assessment. The draw back is AMD additionally locked the CPU in order that technically it might’t be overclocked. MSI has carried out a type of workaround with its Kombo Strike characteristic that is in beta, and a few early exams present combined outcomes.
Earlier than we get to that, let’s discuss in regards to the overclocking lock. That is the primary client desktop CPU to make use of stacked 3D V-cache, and the chip’s packaging know-how doesn’t provide the identical voltage and frequency scaling as AMD’s typical chiplet implementations. Therefore it is optimized and locked (although the Infinity Material and reminiscence interface stay unlocked).
Final week MSI started pushing out beta BIOS updates with its new Kombo Strike characteristic in tow. On the time it was not crystal clear precisely what it does, solely that it has three settings labeled 1, 2, and three (or may be disabled altogether), and purportedly provides to extend efficiency by as much as 5 %. Degree 3 is meant to supply the largest increase, and MSI notes you need to “make sure that [your] CPU cooler is robust sufficient to deal with the warmth.”

Effectively, Reddit person Mannekino just lately posted some fascinating outcomes after taking part in round with the Kombo Strike settings on their MEG B550 Unify motherboard. Cinebench R23, 3DMark Time Spy, and Superposition 1080p Excessive all confirmed a small efficiency acquire when enabling Kombo Strike Degree 3 versus disabling the characteristic. Extra stunning, nevertheless, had been the supposed drop in temps. Here is a glance…

In response to Mannekino, energy and temps each decreased with the Degree 3 setting, whereas efficiency elevated by 2.6-2.8 %. Gaming benchmarks did not yield any actual efficiency good points, however total, they concluded that Kombo Strike was delivering “the identical/barely higher efficiency with means decrease temp and energy consumption.”

Looks like a no brainer to allow if if it is an possibility, proper? Not so quick. Steve Burke at Avid gamers Nexus posted a video right now that paints a special image, and one that’s extra in step with what you would possibly anticipate. He explains that Kombo Strike mainly circumvents AMD’s built-in protections on the Ryzen 7 5800X3D to supply a type of overclocking.

What it actually boils all the way down to is overvolting to spice up clocks just a little bit. Burke examined the characteristic and in contrast the outcomes each to inventory settings, and to a Gigabyte X570 Grasp motherboard, which runs a better vCore out of the gate.

What he discovered is that Degree 1 seems to use an excessive amount of voltage for the frequency, possible due to a coding error—it could possibly be pulling the flawed values from a lookup desk. Degree 3 is extra fascinating anyway as a result of that is the place the largest efficiency acquire is meant to happen. You’ll be able to see the temperature variations at idle within the graph above.

You’ll be able to try the full video for all the main points (it is about 16 minutes lengthy), however summed up, Kombo Strike delivered up a 5 % efficiency bump in manufacturing workloads in comparison with having it disabled, and as much as 3 % over the inventory settings on the Gigabyte platform. In gaming, the outcomes had been negligible. The associated fee to temps is round 2-4C, relying on the workload.

So, there could possibly be some minor efficiency good points available, on the expense of temps. Nevertheless, at this time limit it comes with the unknowns of operating a beta BIOS (and the effort of updating), and simply is not definitely worth the hassle for gaming.
