HEXUS Bang4Watt and Bang4Buck
The performance benchmarks on the previous pages tell part of the story, but it is always fun to add some Bang4Buck metrics into the mix. Do be aware that there are many methods of calculating such results - different benchmarks will skew the outcome, and prices can both fluctuate daily and vary wildly depending on region.
We've chosen to use the multi-threaded Cinebench R20 test as a basis for our results, and pricing was taken from Newegg.com, or SRP pricing, as on July 7, 2020.
These scores simply divide the Cinebench R20 score by the dollar price or SRP.
The two new Ryzens trail their non-T models because whilst the performance is a bit higher, there is a larger difference between the prices. For example, the 3900XT comes in at $499 and the 3900X at $430 - pricing that is mirrored over this side of the pond. The extra Cinebench performance cannot make up for this 16 percent price premium.
This graph divides the same Cinebench result with the system-wide power consumption we observe during evaluation.
Here we see little difference between the X and XT parts because energy consumption is very close.
This metric takes 23.82 as the ceiling for Bang4Buck, and 46.71 for Bang4Watt, and combines them into a weighted score where a maximum of 2 is possible.
As you probably guessed from the top of the page, the XT duo comes in below the X pair, which neatly summarises the value predicament AMD finds itself in, even if we discount the lack of bundled cooling.
