Finally, we have the leaked performance benchmarks of AMD Zen CPU. The company has promised substantial performance improvements over the current architecture, Excavator, which in turn based on the Bulldozer architecture. Bits & Chips brought us those benchmarks, according to credible sources, the first performance test of an AMD Zen processor done under the benchmarking software AIDA64, which detects the CPU as “Zen A0“, which means that it is the first revision of the processor manufactured so more improvements are expected. A clear proof this is the low clock frequency to 3.00 GHz without Turbo boost. The processor is featuring 8 Cores.
The AMD Zen CPU was tested under a motherboard with AMD AM4 socket equipped AMD K17 chipset.
AMD Zen CPU: First Benchmarks Got Leaked Over the Internet
Let’s start with the bandwidth of memory, remembering that it integrates a DDR4 memory controller, where with some modules of DDR4 running @ 2400 MHz with latencies CL14-16-16-31 get a substantial bandwidth equal to an AMD FX- 8350 or an Intel Core i7-6700K, which is normal considering that this is a Dual-Channel configuration, not Quad-Channel like LGA2011 / 2011-3.
At the second we have a CPU Hash benchmark, which measures CPU performance by the SHA1 algorithm defined in the Federal Information Processing Standards Publication 180-4. The code behind this benchmark is optimized for AMD, Intel and VIA and it supports MMX instructions, MMX + / SSE, SSE2, SSSE3, AVX, AVX2, XOP, BMI and BMI2. In this performance test AMD Zen CPU surprised by performing 4 times better than the Core i7-6700K , and even being faster than a 20 – core processor like Intel Xeon E5-2660, so we can assume that this processor is perfect for mining.
The last test is the most real of all because it measures the performance of floating point FP32 Ray-Trace. This performance is slightly lower than Intel Core i7-6700K, but more than double if we compare it with an AMD FX-8350 and this is what matters most. Overall, the source doesn’t reveal much about the CPU, also it is unknown that it was a flagship CPU or not. But one thing which is for sure that their performance will be improved before final launch (might reach 4000 MHz which translate into a 33% improvement).
AMD Zen arrives later this year, so long still lies ahead to further refine the new architecture ahead of official release. According to the source, Zen could end up reaching 4.30 GHz with a TDP of 95W thanks to its manufacturing process of 14nm LPP, which is the improved architecture itself, it is expected that AMD Zen CPUs will give tough time to Intel.
