Intel Skylake Processors To Integrate Iris GT4e Level Graphics Chip - Features 72 Execution Units and Up To 128 MB eDRAM LLC

A few weeks ago, specifications of Intel's Broadwell-U series lineup were leaked which detailed the HD Graphics 6100 serial chipset codenamed Iris. Being the flagship iGPU chip of Intel'south Broadwell lineup, the GT3e fleck volition be replaced by the more powerful GT4e when Skylake hits the marketplace later next yr.

Intel'southward Adjacent Gen Skylake CPUs To Integrate GT4e Graphics Chip With 72 EUs

The information comes from Zauba (via Computerbase) who had listed several of Intel Skylake series fries in a shipping manifesto along with some key details of the processors. Previously, Zauba has given details of a few NVIDIA graphics cards related to GK110 and GM204 which turned out to be authentic so let'southward go on with the details. As we previously detailed, Broadwell will feature iv iGPU configurations which include GT1, GT2, GT3 and GT3e.

The GT3e "Iris Pro" level graphics chipsets which include the Hard disk drive 6100 "Iris" GT3e with 48 Execution Units and 128 MB eDRAM cache, The GT3 Hard disk drive 6000 comes with 48 Execution units and no L4 cache, HD 5300/5500 GT2 graphics chip with 24 Execution units and GT1 HD Graphics chip with but 12 Execution units. Broadwell has increased the EU count past 50% and there are seven H/W threads per European union with 128 GRF registers per thread along with simultaneous multi-threading support.

While Broadwell has already launched with the Core Chiliad "Broadwell-Y" series processors, the real chips will start shipping at CES 2022 where Broadwell-U series volition enter the market. Broadwell K-Serial is existence planned for a Q2 2022 launch only at the same time, Intel has announced Skylake-Southward series which will be bachelor to consumer market featuring lower TDPs. The Skylake-S serial chips volition be part of a diverse desktop and notebook based platform only beingness based on a fourteen nm process node, Skylake processors would feature a new architecture along with several CPU and GPU side enhancements whereas Broadwell is meant to improve upon the compages which was first introduced on Haswell processors. The following chart shows the main differences in the next generation Skylake processor configurations:

TDP	4W	15-28W	35-45W	35-95W

Compared to Haswell and Broadwell, we are looking at some decent extension in the number of Execution Units till the GT3 iGPU merely the GT4e is way across the GT3e chips with 72 Execution Units. The chip volition be featured across the Syklake Southward/H/K series processors with 64 MB eDRAM cache on LGA variants and 128 MB eDRAM cache on BGA variants.

Bated from all these details, the SKUs for Skylake have besides been confirmed along with their TDPs. The desktop variants will have six dissimilar variants which will include the flagship 95W Quad Cores with GT2 and GT4e GPU while the lowest 35W TDP variant will feature Dual Cores and GT2 graphics. The H-Series lineup will besides include the 95W Quad Core with GT4e graphics chip but that'southward the simply flagship chip followed past 65W, 55W and 45W Quad Cadre variants with a mix of GT4e and GT2 graphics. This H-Series doesn't seem to include a dual core model at all. The U-Series lineup will have TDPs of 25W and 15W with the flagship role featuring Dual Cores and GT3e graphics while the other models consist of GT2 graphics. Last upwardly is the Y-Series Skylake lineup featuring two SKUs, both featuring 4.5W TDP and ii Cores plus GT2 graphics.

Broadwell will stick to the LGA 1150 socket and remain compatible with current 9-Series chipset motherboards while Skylake will shift focus to the next mainstream chipset known as the Z170. The chipset volition feature up to xx PCIe Gen 3 lanes, 6 SATA Gen iii ports, 10 USB 3.0 ports and a total of 14 full USB ports (USB 3.0 / USB 2.0), up to 3 SATA Express capable ports, up to 3 Intel RST capable PCI-east storage ports which may include x2 SATA Express or M.2 SSD port with Enhanced SPI and x4/x8/x16 capable Gen 3 PCI-Express back up from the processor. Aside from that, nosotros know that the Skylake processors would be uniform with the latest LGA 1151 socketed boards and Z170 chipset which is role of the new 100-Series chipset replacing the nine-Serial "Wild Cat" PCH. The second most interesting thing covered is that Skylake processors would accept both DDR3 and DDR4 retentivity controllers so the dissimilar SKUs tin can exist configured to use either of the retentiveness type.

The divergence between them is not clearly mentioned however we recollect its related to clock speeds. You lot tin get a better representation of the variants in the following chart:
