AMD Zen based Summit Ridge CPU Beats Intel’s $1000 Broadwell-E i7 6900X
During an event held at San Francisco, AMD finally provided details about their upcoming Zen architecture. The company also demonstrated performance of their eight core, 16 thread Zen based Summit Ridge processor against a similarly configured Intel Broadwell-E processor.
Zen CPU has been in making for many years. It is one of the most anticipated products the chips maker has ever produced. With Zen, AMD claims that it has made multiple architectural advances designed to increase the performance throughput efficiency. This should help AMD once again take the fight to Intel.
In fact, Zen based CPUs should be able to rival not only high-end Intel processors but are also scaled down to meet the needs of a broad range of applications.
In addition to what we already know, AMD confirmed that the desktop versions will utilize a new cache memory hierarchy. They will feature 8MB of L3 cache along with a significantly enhanced pre-fetcher, seperate low latency L1 instruction and data caches as well as a large unified L2 cache.
AMD Zen is built on the same 14nm FinFET process as their Polaris GPUs. AMD also revealed that it has improved the instruction schedule window by 1.75 times and its execution resources by 1.5 times. Overall, Zen will potentially provide around five times the amount of bandwidth compared to previous designs.
The only thing that AMD fans won’t be delighted to hear is that Zen has been delayed until early 2017. Expected to launch first, the Zen based Summit Ridge desktop CPUs will utilize the AMD AM4 socket. This new socket will unify AMD’s platforms and will also support 7th generation AMD A-series desktop processors, previously codenamed Bristol Ridge.
Interestingly, while AMD Zen has been pushed back until next year, the AM4 platform hasn’t been. The first desktop systems featuring the 7th gen A-series APUs on the brand new AM4 socket are scheduled to ship in the second half of 2016.
At the event, AMD demoed the real-world performance of Zen based Summit Ridge versus Intel’s $1000 Broadwell-E i7 6900X CPU. The processors were compared at identical clock speeds of 3 GHz using the multi-threaded blender rendering software.
Both systems started the same blender session at the same time and AMD CPU was able to render the scene in about half a second faster than Intel chip. This indicates that Zen might have a better IPC than Intel’s highest performing desktop CPUs yet.
However, we still don’t know about AMD Zen’s target clock speeds, thermal output, pricing and so forth. That being said, AMD plans to provide additional details at next week’s Hot Chips conference so you should have some juicy information soon.
Wrapping it up, Zen based Summit Ridge processor appears to be really powerful and as the demo proves, it could give tough competition to Intel’s Bradwell-E CPUs.
