First AMD Zen Benchmarks Leaked, Summit Ridge CPUs On Par with Intel Broadwell-E Chips
Update: Turns out this was an April Fool’s joke, which means the benchmark images below are fake so please disregard them.
Rumors surrounding AMD’s much anticipated Zen architecture have been making rounds for a while. The US based chip maker is expected to launch their first Zen based chips, code-named Summit Ridge, in Q4 this year — more specifically this October.
If previous reports are to believed, the 8 core Summit Ridge CPU dies have already taped out in January, and are currently being tested and validated. Rumor has it that these CPUs feature a 95W TDP and will be released on the new AM4 socket.
The 95W TDP if accurate, alongside 8 high performance Zen cores with multi-threading, indicates that the next gen desktop FX CPUs from AMD are indeed very power efficient and should be on par with Intel’s new CPU lineup launching this June.
That being said, folks over at Bits&Chips have just leaked some screenshots relating to AMD Zen benchmarks. According to the site, the sample tested is an 8-core Summit Ridge CPU running at 3.0 GHz.
In terms of the DDR4 bandwidth, AMD Zen appears to be on par with the Core i7-6700K CPU, with CPU Hash around three times better than the Hash score of the i7-5820K, and even slightly better than a 20 core Xeon.
The FP32 Ray-Trace score is comparable to the i7-4930K, so it’s not as amazing as the CPU Hash. The low score indicates that Zen might have a weak FMA implementation, though the floating-point unit (FPU) will be close to that of the Intel’s best.
In fact, the report goes further to state that the 8-core Summit Ridge CPU will have a performance similar to that of the Broadwell-E CPUs.
AMD’s Zen chips are based on a new 14nm FinFET process technology. Built from scratch, the new architecture stacks transistors on top of each other, an upgrade over placing them next to each other, which improves performance as well as power efficiency.
Further, AMD Preisdent & CEO Lisa Su stated at the company’s Q4 2015 Earnings Call that Zen-based CPUs will bring greater than 40% improvement in instructions per clock (IPC) over their current lineup – which is undoubtedly a great jump by any standard.
Last but not least, these new FX CPUs include support for a new socket with DDR4 memory and PCI Express Gen 3.0.
