Here’s Why Intel Cancelled High-end Skylake-C Processor
Intel has decided to kill one of its top-of-the-line processors for undisclosed reasons, and according to various reports, the move could be more financial than performance-related.
For a little background, Intel announced a processor branded as Broadwell-C back in June. The quad-core Broadwell processor features Intel’s best Iris Pro graphics and an on-package eDRAM cache aimed at desktop PC enthusiasts.
The folks over at The Tech Report tested the processor alongside older high-end Intel processors and Skylake, and found that Broadwell-C outperformed Intel’s latest Skylake processor, the Core i7-6700 – thanks in part to an insane 128MB L4 cache and its much larger GPU.
It’s worth mentioning here that the Skylake 6700K is specifically designed for enthusiasts, while the 5775-C is aimed at content creators and gamers. So a direct comparison between the two would be a bit of mismatch. But still, the potential for a Skylake-C could be a real killer chip.
Unfortunately that’s not going to happen as Intel has decided to kill the Skylake-C processor. The company is set to release a broad range of Skylakes for handhelds, tablets, laptops and desktops, many of which are already announced, but a Skylake-C isn’t in the cards this time around.
But, why would Intel do this with Skylake-C? Well, Broadwell-C chips based on the Skylake architecture are actually a really bad deal for Intel.
According to AnandTech, the Skylake processors have die sizes of 122.4 square millimeters, while the Broadwell-C is around 160 square millimeters.
That means fewer CPUs per wafer, which potentially lowers yields, and with the on-chip eDRAM cache comes increased manufacturing costs. In other words, a combination of increased cost and lower yield is why the Skylake-C was killed.
Intel did confirm that it won’t launch this processor, but won’t disclose an official reason behind it.
