A Wall Street analyst, with no thought to his personal safety, has dared to question what AMD fans have been telling us for ages – Zen will bring about peace on earth, cure cancer and above all give Intel a good kicking.
However, Christopher Danely with Citigroup has bravely claimed that with its “Kaby Lake” family of processors, Intel remains a “step-function ahead of AMD Zen when Zen chips are released in Q416.”
He also doubts the benchmark stats that AMD presented to promote Zen’s capabilities relative to Intel’s microprocessors claiming that the AMD controlled benchmark compared an engineering sample of a Zen processor that has not been released yet against a three-month old Intel processor, with both chips clocked at 3.0 Ghz.
“We note the maximum speed for the Intel chip is 3.2 GHz. The result showed AMD completing the benchmark 2 per cent faster than Intel, implying higher CPU efficiency on a “clock for clock” basis. AMD kept both 8 core chips at the same clock speed of 3.0 Ghz, below the native clock speed of the Intel chip. The benchmark result showed the Zen Summit Ridge processor completing the Blender rendering benchmark in 48.07 seconds, 2 per cent ahead of Intel Broadwell-E chip’s time of 49.06 seconds. We note this is only one benchmark using a custom workload performed at an AMD event under controlled conditions, and therefore cannot be verified by third parties and does not represent expected results under all workloads, Danely said.
Instead he thinks that Chipzilla will benefit from its process technology lead while AMD’s manufacturing partner, Global Foundries, which has a “spotty track record.”
“After several of delays and eventually failing to develop 20nm and 14nm on its own, GlobalFoundries entered into a partnership agreement with Samsung in April 2014 to adopt Samsung’s 14nm FinFET process. Despite using the same tools, recipes, and materials as Samsung’s 14nm process, products built on GlobalFoundries’ 14nm did not appear until earlier this year, roughly a year after Samsung released its Exynos 7420 SoC built on its 14nm process,” Danely pointed out.
Since the partnership agreement with Samsung does not include 10nm or lower nodes, we think the technology gap between AMD and Intel will widen again once Intel migrates to 10nm next year.
Meanwhile Intel released its new Kaby Lake chips on an improved 14+nm process this month, featuring a 15 per cent performance improvement over its Skylake chips. Kaby Lake chips deliver up to 12 per cent faster productivity performance and 19 per cent faster web performance over comparable Skylake chips
“We expect independent benchmarks to show Intel’ performance is a step function ahead of AMD Zen when Zen chips are released in 4Q16,” he said.
Below you will find lots of rantings from Intel and AMD fanboys and we expect the language to be colourful. Those of a sensitive disposition might want to look away now.
