Core i9

Intel launched brand new X-series high end desktop CPUs along with a brand new X299 chipset. The company also launched the new Intel Core i9 series, and the 18-core Core i9 Extreme Edition. Availability and pricing details in India should be known in the coming months.

Intel Core-X Series and Core i9 CPUs

Under Kaby Lake-X architecture, there are two new SKUs – a Core i7-7740X and a Core i5-7640X. The Core i7-7740X is a quad-core CPU running at 4.3GHz with a boost clock of 4.5GHz, it has support for HyperThreading, has 8MB of L3 cache and supports 16 PCIe 3.0 lanes. The Core i5-7640X will run at 4GHz with a boost clock of 4.2GHz and does not support HyperThreading. The L3 cache is also a bit lower at 6MB but it does support the same number of PCIe lanes. Both CPUs will support dual channel DDR4 memory up to 2666MHz and have the same TDP of 112W. Kaby Lake-X CPUs won’t support Intel’s Turbo Boost Max 3.0 technology.

Skylake-X CPUs will support Intel’s Turbo Boost Max 3.0 technology (except for the Core i7-7800X) along with higher core counts (up to 18 cores), more than double the PCIe lanes and support for quad-channel DDR4 memory. Intel has so far announced three SKUs for the Skylake-X CPUs, starting with the Core i7-7800X. This CPU runs at 3.5GHz with boost clock set to 4GHz and features six cores with HyperThreading. The slightly faster Core i7-7820X CPU runs at slightly higher clock speed but also packs in eight cores with 11MB of L3 cache and 28 PCIe lanes.

The extreme edition SKUs will come under the brand-new Core i9 series. We only have details about the Core i9-7900X CPU now. It is a 10-core CPU running at 3.3GHz with a boost clock of 4.3GHz and Turbo Boost Max 3.0 speed of 4.5GHz. The Core i9-7900X has support for HyperThreading, has 13.75MB of L3 cache and supports 44 PCIe 3.0 lanes. Intel has listed the names of future Core i9 CPUs but haven’t revealed finer details of clock speeds, cache, etc, yet. This includes the 12-core Core i9-7920X; 14-core Core i9-7940X; 16-core Core i9-7960X and the insane 18-core Core i9-7980XE.

All CPUs under the Core-X family will be using the new X299 chipset, with a new LGA 2066 socket. This new chipset introduces features like DMI 3.0 link which should help improve throughput times and support for Intel Optane memory. It also brings I/O capabilities like support for up to 24 PCIe 3.0 lanes, up to eight SATA 3.0 ports and up to 10 USB 3.0 ports.

Speaking on the launch, Gregory Bryant, Corporate Vice President and General Manager Client Computing Group said in a blog post, “The Intel Core X-series processor family introduces a series of firsts that reflect the extreme performance we are delivering. This family includes Intel’s first teraflop desktop CPUs, a prime example of just how much raw compute these processors can handle. We’re also introducing the entirely new Intel Core i9 processor, representing the highest performance for advanced gaming, VR and content creation. At the top of the lineup is the new Intel Core i9 Extreme Edition processor – the first consumer desktop CPU with 18 cores and 36 threads.”
