Now this is probably the most interesting news so far for 2018! Dual IGP on Intel’s Core i7-8809G mobile processor!
Intel revealed specifications of its upcoming “Kaby Lake + AMD Vega” multi-chip module, the Core i7-8809G, on its website. A number of these specs were already sniffed out by Futuremark SystemInfo, but the website sheds light on a key feature – dual integrated graphics. The specs sheet confirms that the chip combines a 4-core/8-thread “Kaby Lake” CPU die with an AMD Radeon RX Vega M GH graphics die. The CPU is clocked at 3.10 GHz, and SystemInfo (from the older story) confirmed that its Turbo Boost frequency is up to 3.90 GHz. The L3 cache amount is maxed out a 8 MB. The reference memory clock is set at dual-channel DDR4-2400. What’s more, the CPU component features an unlocked base-clock multiplier.
Things get interesting with the way Intel describes its integrated graphics solution. It mentions both the star-attraction, the AMD Radeon RX Vega M GH, and the Intel HD Graphics 630 located on the “Kaby Lake” CPU die. This indicates that Intel could deploy a mixed multi-GPU solution that’s transparent to software, balancing graphics loads between the HD 630 and RX Vega M GH, depending on the load and thermal conditions. Speaking of which, Intel has rated the TDP of the MCM at 100W, with a rider stating “target package TDP,” since there’s no scientifically-correct way of measuring TDP on a multi-chip module. Intel could build performance-segment NUCs with this chip, in addition to selling them to mini-PC manufacturers.
Specifications of the RX Vega M GH continue to elude us. All we know is that it has its own 4 GB HBM2 memory stack over a 1024-bit wide memory interface, ticking at 800 MHz (204.8 GB/s memory bandwidth), and a GPU engine clock of 1.19 GHz. Even if this chip offers performance in the neighborhood of the discrete Radeon RX 570 4 GB, it should make for a killer entry-level gaming solution. Motherboards based on it could quickly capture the gaming iCafe, entry-gaming PC, and performance AIO markets.
