Usually we would not report on one thing like this, as a result of finally “some man on a discussion board stated a factor” is not precisely newsworthy by itself. Nonetheless, on this case, the poster in query is Kepler_L2, a widely known fellow who continuously shares insider info and astute evaluation of upcoming {hardware}, significantly for AMD.
Posting on the AnandTech boards in a long-running thread about Zen 5, Kepler_L2 replied to a consumer asking about particular claimed efficiency will increase on AMD’s next-gen processors within the well-liked SPECint benchmark. SPECint is a check that measures a CPU’s pure integer math prowess, and whereas it would not actually have a lot relation to client consumer desktop workloads, it is nonetheless significant within the high-performance compute (HPC) area.
That signifies that these rumored beneficial properties are nearly completely from the main redesign of the CPU core that is coming with Zen 5. AMD has acknowledged unambiguously (see above slide) that Zen 5 would be the first complete rejig of the Zen CPU core since its introduction, and for those who’re ever going to see a “better than 40%” efficiency acquire from core modifications, a clean-sheet do-over like that is the time, so it is not completely unbelievable.
Posters within the thread level out that 40% occurs to have been AMD’s purpose with the unique Zen structure, and the corporate exceeded that quantity considerably within the remaining merchandise. Nonetheless, AMD was evaluating to its personal previous-generation “Piledriver” CPUs at the moment, and for those who’re studying this, you in all probability know the way these chips went down. Zen 4 is a a lot greater mountain to climb for those who’re attempting to attain a 40% efficiency acquire. We reckon AMD will verify or deny these rumors in its presentation at Computex barely greater than a month away.
