First AMD Zen Benchmarks Show 10% IPC Gains Over Intel Core i5-4670K
The first verified AMD Zen benchmarks have leaked out which show huge IPC gains over previous architectures, even when running at much lower clock speeds. There is one thing to take note of, however, that is this performance data comes from early engineering samples which run on motherboards with pre-release BIOS versions so the results are not entirely representative of the final product.
The AMD Zen benchmarks leaked via the Ashes of the Singularity built in test show a 38% performance improvement with the 8-core Zen ES over the older FX 8350. The IPC gains are impressive given the fact that the Zen ES has core clock speed of 2.8 GHz base and 3.2 GHz boost compared to the FX 8350 with clock speeds between 4.0 and 4.2 GHz.
The AMD Zen ES CPU also manages to outperform Intel’s Core i5-4670K by around around 10% on the same benchmark and GPU configuration, but couldn’t edge out the Core i7-4790. Though it’s worth noting that the Zen based CPU runs at much lower clock speeds. That being said, the frequencies could get a raise by the time the product is officially launched.
When it comes to specs, AMD Zen engineering samples are currently set at revision A0. There are four chips in total that are allegedly available to some manufacturers. Two of these Zen ES chips are designed for desktop AM4 motherboards while the other two are designed for AMD’s SP3 server platform. Details are as follow:
- AM4 4 cores with 65W TDP
- AM4 8 cores with 95W TDP
- SP3 24 cores with 150W TDP
- SP3 32 cores with 180W TDP
The TDP are fairly low especially when we consider that Zen based CPUs support simultaneous multithreading (SMT). Further, both quad- and octa-core AM4 chips would run at same clock speeds as mentioned above, and feature 8 and 16 threads, respectively. The quad-core variant has 2 MB L2 cache and 8 MB L3 cache, while the amount gets doubled for the octa-core variant.
AMD showcased the high performance octa-core Summit Ridge CPU at this year’s Computex event. The Zen based CPU is said to offer more than 40% IPC gains over the current FX lineup, and would compete directly with Intel’s Skylake offerings in terms of performance, power and price.
As for availability, first AMD Zen based products are expected to arrive early next year at CES 2017.
