AMD Radeon RX Vega 11 vs NVIDIA GeForce GTX 1070 SLI (Laptop) vs AMD Radeon RX Vega M GH

AMD Radeon RX Vega 11

The AMD Radeon RX Vega 11 is an integrated GPU in the Ryzen desktop APUs (e.g. Ryzen 5 2400G) that were launched early 2018. The graphics card is based on the Vega architecture (5th generation GCN) and has all 11 CUs (=704 shaders) clocked at up to 1240 MHz (Ryzen 5 2400G). The GPU benefits from fast dual-channel DDR4-2400 RAM (contrary to DDR4-2133 single-channel, which is also possible).

The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. More information is available in our dedicated article about the Raven Ridge architecture.

According to a first 3DMark Fire Strike that was published by AMD, the Vega 11 offers a similiar theoretical performance as the older dedicated Radeon R9 M280X. In games the missing dedicated graphics memory may however prove to be a bottleneck. Therefore, modern and demanding games will only be playable in lowest settings and the APU is mostly intended for lower demanding games like Overwatch, Dota 2, ...

Thanks to the 14nm process and clever power-saving features, the power consumption is comparatively low. The high TDP of 65 Watt of the APU however should lead to a much higher power consumption compared to the mobile APUs with 15 Watt TDP.

NVIDIA GeForce GTX 1070 SLI (Laptop)

The Nvidia GeForce GTX 1070 SLI for laptops is a combination of two GTX 1070 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1070 to up to 90% faster performance. In most games with SLI support, the GTX 1070 SLI is therefore faster than a single GTX 1080. However, sometimes the combination also suffers from micro-stuttering.

The technical details of the card are identical to a single GTX 1070 (see for more information) and the power consumption is doubled. Therefore, the 1070 SLI combination is only found in huge clunky laptops.

AMD Radeon RX Vega M GH

The AMD Radeon RX Vega M GH is an integrated GPU in the fastest Intel Kaby-Lake-G SoC. It combines a Kaby-Lake processor, a Vega graphics card and 4 GB HBM2 memory on a single package. The graphics card offers 24 CUs (1536 shaders) and is clocked from 1063 - 1190 MHz.

Currently it looks like the GPU is a mixture of Polaris (Shaders?) and Vega (HBM memory controller at least). E.g. the graphics card is called Polaris 22 internally. Detailed information on the Vega architecture can be found in our dedicated article about the Raven Ridge architecture.

The performance of the Vega M GH should be slightly slower than a dedicated Nvidia GeForce GTX 1060 for laptops according to benchmarks from Intel. Therefore, it should be well suited for 1080p and high resolution gaming.

The power consumption should be quite similar to a dedicated Vega Mobile GPU, but due to the small form factor, smaller laptops can be built with the Kaby-Lake-G SoC. The TDP is specified at 65 Watt for the whole package including GPU, CPU and HBM2 memory.
