Following surprise announcement of an Intel-AMD collaboration, for new CPU new product, which will be part of our 8th Gen Intel Core family, brings together our high-performing Intel Core H-series processor, second generation High Bandwidth Memory (HBM2) and a custom-to-Intel third-party discrete graphics chip from AMD’s Radeon Technologies Group all in a single processor package.

Intel’s new CPUs are expected to carry the “Kaby Lake G” codename, where the G goes for the much-increased graphics power of these solutions compared to other CPUs. For now, the known product names point to one Intel Core i7-8705G and Intel Core i7-8809G. Board names for these are 694E:C0 and 694C:C0, respectively.

The discrete AMD Radeon GPUs on these multi-chip modules (MCMs) are both being reported as packing 24 compute units with a total of 1536 stream processors, and the clock rates vary between 1000 MHz for the 694E, a 20% reduction from the 1190 MHz for the 694C version. Both solutions come with 4 GB of HBM2 memory, and the CPUs are 4-core, 8-thread Kaby Lake parts running at 3.1 GHz and 4.1 GHz Turbo, with the 694C version having its HBM2 memory clocked at 800 MHz versus 700 MHz on the 694E one.

According to benchmarks from GFXBench, we can see that the Intel Core i7-8809G has an almost 50% performance advantage compared to the Core i7-8705G. This can probably be laid at the feet of the lower GPU core and HBM2 clocks, though it’s likely there’s some sort of power management features or different TDP configurations, considering the products these SKUs are expected to power? It’s also very possible that the Core i7-8705G (694E) features a cut-down version of the AMD GPU as well.

On GeekBench, the Intel Core i7-8809G scoring 76,607 points on OpenCL, but clocks are reported as 1 GHz than the 1190 MHz previously seen on GFXBench.

YouTuber Tum Apisak’s 3D Mark scores and hardware data on the 3D Mark 11 Benchmark (Performance preset) shows the expected performance of the Core i7-8809G compared to the Core i7-8705G, where the former is around 30% better in graphics tests than the latter. However, the fact that the Core i7-8705G just manages to win against the Core i7-8809G on the CPU tests, which does confirm the presence of a cut-down GPU. Lower power draw from the GPU likely means that the CPU has more thermal and power headroom to achieve its Turbo clocks for longer, which may help explain the higher CPU score.

Finally, a real benchmark, from Ashes of the Singularity benchmark, the 694E:C0 part, Core i7-8705G’s MCM delivering both a 3,900 and 4,800 score Settings were at Low preset, 1080p, where the MCM managed to achieve a 62.9 average framerate on its best run.

Intel and AMD Radeon Technologies Group team up is quite exciting and should give us better products but when the Zen APUs are available the competition between old rivals will heat-up again. So far rumors and benchmarks look great and only time will tell how this new collaboration will go.
