AMD Ryzen 9 5900X CPU-Z Bench Score Leaks, 27% Higher 1T Performance Over 3700X
With AMD expected to announce its 5th Generation Ryzen "Vermeer" desktop processors next week, the rumor-mill is grinding the finest spices. This time, an alleged CPU-Z Bench score of a 12-core/24-thread Ryzen 9 5900X processor surfaced. CPU-Z by CPUID has a lightweight internal benchmark that evaluates the single-threaded and multi-threaded performance of the processor, and provides reference scores from a selection of processors for comparison. The alleged 5900X sample is shown belting out a multi-threaded (nT) score of 9481.8 points, and single-threaded (1T) score of 652.8 points.
When compared to the internal reference score by CPUID for the Ryzen 7 3700X 8-core/16-thread processor, which is shown with 511 points 1T and 5433 points nT, the alleged 5900X ends up with a staggering 27% higher 1T score, and a 74% higher nT score. While the nT score is largely attributable to the 50% higher core-count, the 1T score is interesting. We predict that besides possibly higher clock-speeds for the 5900X, the "Zen 3" microarchitecture does offer a certain amount of IPC gain over "Zen 2" to account for the 27%. AMD's IPC parity with Intel is likely to tilt in its favor with "Zen 3," until Intel can whip something up with its "Cypress Cove" CPU cores on the 14 nm "Rocket Lake-S" processor.

TPUs own analysis showed that the performance difference between the 3100 and the 3300x is 12% due to the respective two vs one CCX design, and since then I've postulated that this (along with the cache redesign, 17%-20% IPC gains and 200-300mhz frequency bump), the total performance uplift could be upwards of 30%...Can't wait to upgrade my 2700x for a 5900x and my X470 for an x670
Very impressive results atm. I might finally go AMD : )
Yeh it's nice to have bragging rights and feel like it's future proofing your system, but i'd be willing to wager most people would upgrade their system once more before DDR4 and PCIe 4.0 become irrelevant.
I've learnt my lesson over the years, new and shiny doesn't always translate to being better.
I'm not telling you how to spend your money, but I personally won't be buying a new CPU until something comes along that needs more. At the moment I'm mostly just bouncing off the upper refresh-rate of my monitor and TV and discarding frames.
"As for performance, the chip scored 652.8 points in the single-core test which is 27% faster than the AMD Ryzen 7 3700X and up to 25% faster than the Ryzen 9 3900X.
Coming to the multi-threaded performance test, the alleged AMD Ryzen 9 5900X CPU scored a total of 9481 points which is a massive 75% improvement over the Ryzen 7 3700X & a 15% improvement over the Ryzen 9 3900X."
Why only 15% higher score than 3900X in multicore? That's lower than the alleged IPC uplift - for almost 50% higher TDP, presumably. Something's not right.
It's strange that 3900X to 5900X wouldn't follow the same pattern, especially with the TDP and frequency uplift. I could imagine this result if processor was thermally or power limited.
