AMD Radeon RX Vega 7 vs NVIDIA GeForce GTX 1070 Mobile

AMD Radeon RX Vega 7

The AMD Radeon RX Vega 7 is an integrated GPU for notebooks. It is used in the Ryzen 4000 and Ryzen 5000 mobile APUs. The GPU is based on the Vega architecture (5th generation GCN) and has 7 CUs (= 448 shaders) clocked at up to 1,800 MHz. The iGPU's performance depends on the TDP of an APU (15, 35, 45 W or cTDP), the clocks, the cooling, and the memory configuration). The GPU should benefit from fast dual-channel DDR4-3200 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.

The performance should be slightly lower than the older RX Vega 8 GPU (1 CU more, but lower clock speed). That means, only some demanding games of 2019 will run in lowest detail settings. Less demanding games like Fifa 20 or Dirt Rally 2.0 should run in higher settings and 1920 x 1080.

Thanks to the 7 nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the iGPU won't look out of place in a slimmer, lighter laptop.

NVIDIA GeForce GTX 1070 Mobile

The Nvidia GeForce GTX 1070 is the second fastest Pascal based graphics card in mid May 2016. It comes in two variants, the desktop version (see here for the detail page) with 1920 shaders and the mobile variant with 2048 shaders and lower clock rates. Both cards are based on a cut down GP104 chip (like the GTX 1080) and are manufactured in 16 nm FinFET at TSMC.

Compared to the GTX1080, the GTX1070 features less CUDA cores (2048 versus 2560) that are clocked a bit lower (maximum Boost 1645 versus 1733). Instead of the new GDDR5X, the GTX 1070 uses slower GDDR5 graphics memory - but still 8 GB. The TDP is also reduced and rumored to be 10 Watts higher than the predecessor, the GTX 980M.

For thin and light laptops Nvidia offer a Max-Q called version of the GTX 1070 with lower TDP and also significantly lower performance. Sadly this variant im sold with the same GTX 1070 name, making it hard to judge the performance.

The performance depends on the cooling solution of the laptop. With a good fan system, the performance of the laptop version is on par with the desktop GTX 1070 (Founders Edition). Nvidia claims that partner solutions can be up to 10 percent slower however. In our benchmarks with various laptops the performance ranged from -5 to -14% slower performance compared to partner models of the GTX 1080 desktop models with slightly higher clocks.

On average the GTX 1070 is around 20 percent faster than the old mobile GeForce GTX 980 and therefore the second fastest mobile graphics card (non SLI). Therefore it is capable of WQHD and 4K gaming in high settings (see game benchmarks below).

The GP104 chip is manufactured in 16nm FinFET process at TSMC and offers a range of new features. DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP), improved H.265 video en- and decoders (for PlayReady 3.0) are only some of the improvements. See our detailed Pascal architecture article for more details.

The power consumption of the GTX 1070 is specified with 115 Watt TGP according to Nvidia and therefore slightly above the old GeForce GTX 980M. This leads to rather big and clunky gaming laptops that use the GTX 1070. The later released Max-Q version of the GTX 1070 uses only 80 - 90 Watt TGP and is therefore better suited for thin and light laptops.
