Intel, AMD announce 8th-gen processor with Radeon Graphics
Intel Officially Launches 8th Generation Core Processors With AMD Radeon RX Vega M Graphics and HBM2 VRAM – 1536 Stream Processors, Quad Core CPU, Up To 200 GB/s Bandwidth.
While made to be thin and light, Intel guarantees that overclocking will be available on all dies (for the top variant) such as CPU, GPU and HBM2. The various SKUs will be configured in 65W and 100W variants while we’ll expect OEM solutions from Dell, HP and designs such as Intel’s NUC within Q1 2018.
Intel 8th Generation Core Processors With Radeon RX Vega and HBM2 – Specifications In Depth
Now talking about how the dies access each other on the new chips. The GPU and HBM2 dies are connected directly by the EMIB interconnect while the CPU is connected to the GPU via eight lanes of PCI Express Gen 3. This is said to provide the necessary throughput to feed graphics intensive workloads and the remaining PCIe lanes are available for direct CPU access. In terms of efficiency, HBM offers up to 80% less power than a traditional GDDR5 solution which would also take up a bit more space than the said HBM2 solution.
This system is known as Dynamic Tuning and works by checking the current status of both CPU and GPU to confirm their usage scenario and share power to the more workload intensive parts of the chip. In the end, this could lead to a up front design benefit of 17.5W when comparing a system with Dynamic Tuning turned on and off. That’s just about an 18% increase in efficiency and mobile platforms can take benefit from every bit of it.
Intel 8th Generation Core Processors With AMD Radeon RX Vega M Graphics and HBM2 – Meet Radeon RX Vega 24 and Radeon RX Vega 20
I guess the most interesting part about these chips is the fact that they are the first mobility design to pack discrete AMD Radeon RX Vega graphics. There are specifically two variants that are going to be available on the Intel 8th Generation core processors, these include the Radeon RX Vega 24 and the Radeon RX Vega 20.
