It's easy to imagine that the i7-6785R may deliver better frame-time performance than a Core i7-6700K thanks to its similar CPU architecture, clock speed, 元 cache, and even Iris GPU EUs (not that you'd use the IGP for demanding games). That chip delivered impressive gaming benchmarks across the board, thanks to its 128MB of eDRAM. From our i7-6700K review, we saw the i7-5775C was a surprise contender. The most familiar 65W Iris CPU to our readers may be Intel's Core i7-5775C, which matches up well with the i7-6785R based on Intel's ARK specifications. Because of the thermal demands of a 65W chip, it's unlikely we'll see a Skylake-R chip in this product segment. Those machines seem capable of entry-level gaming on their own, but they can't replace a midrange or high-end discrete GPU. As the i7-6770HQ is the Iris variant of the i7-6700HQ, we can also find this level CPU performance in laptops like Dell's XPS 15. Moving into the 45W TDP range, we have NUCs like Intel's Skull Canyon, powered by the Core i7-6770HQ. The caveats are that the i7-6567U has less 元 cache (4MB versus 6MB), a smaller 64MB eDRAM cache, and Hyper-Threading support compared to the dedicated quad-core hardware of the Core i5-6585R and Core i5-6685R. The i7-6567U's 3.3 GHz base and 3.6 GHz Turbo clocks compare well with the i5-6685R's 3.2 GHz base and 3.8 GHz turbo speeds. This CPU could easily have been omitted were it not for the fact that it supports the same number of threads and is clocked competively with the i5-6585R and i5-6685R. The 28W Core i7-6567U is available in the likes of the Vaio Z flip. My hope with 65W CPUs is that manufacturers will be aware of the thermal demands of the chip and provide sufficient cooling that won't hamper the R-series chips' performance.

Those aggressive thermal constraints can sometimes be overcome with software such as TechPowerUp's ThrottleStop, though. That's because modern CPUs with integrated graphics often have to balance their thermal budgets between these resources. A real concern, as evidenced by posts on Reddit and Ultrabook Review, is that these devices are known to have issues with throttling due to insufficient cooling or aggressive thermal limits. Those 15W CPUs are a far cry from the 65W R-series.

I've compiled this table of Intel ARK data on a wide range of CPUs with Iris graphics so that we can discuss what a 65W Skylake R-series system might look like.Īt the low-end of the TDP scale, we find products such as the Core i7-6650U-powered Microsoft Surface Pro 4 and the Core i7-6560U-powered Dell XPS 13. Thicker gaming or workstation notebooks are usually built with Intel's 45W CPUs in mind. Peering through the clouds at Skylake, we know that thin laptops are typically built with Intel's 15W Core i chips or even more power-sipping Core M chips. That leaves me wondering what products these CPUs are destined for.įrom the thousand-foot level, low-TDP CPUs are suited towards mobile computing and high TDPs towards desktop PCs. But even mobile and embedded isn't the right fit for the Skylake R-series CPUs, as their 65W TDP is a pretty hefty hurdle for mobile or embedded cooling solutions to clear. Since these aren't socketable chips, they're closer to mobile or embedded processors that use a ball-grid-array (BGA) motherboard connection. That's in keeping with Intel's previous guidance that it won't be releasing socketable Skylake CPUs with Iris graphics. While the R-series Skylake chips are officially classified as desktop CPUs, they won't be socketable parts like the Core i7-5775C. Intel's ARK indicates that these CPUs include improved turbo boost speeds and an 元 cache that matches that on board the Skylake K-series chips, an improvement over Broadwell R-series chips.Ĭongatec's TS170, an embedded system that uses Intel's Xeon E3-1515M v5 CPU with a similar Iris Pro P580 IGP The highlight of these CPUs for enthusiasts may be the 128MB of eDRAM that Iris Pro brings with it, though. That setup should make for a solid entry-level graphics solution. Those three slices offer up 24 execution units (EUs) each, for a total of 72 EUs. These new chips are all quad-core CPUs paired with Iris Pro graphics, which means we get three Skylake Gen9 GPU slices. Intel is set to launch its 65W Skylake R-series CPUs this quarter in the form of the Core i5-6585R, the Core i5-6685R, and the Core i7-6785R.
