AMD Radeon RX Vega 10 vs NVIDIA GeForce GTX 1070 (Desktop) vs NVIDIA GeForce GTX 1080 Mobile

AMD Radeon RX Vega 10

The AMD Radeon RX Vega 10 is an integrated GPU for notebooks. It is used for the Ryzen 7 APUs, which were launched in the end of 2017. The GPU is based on the Vega architecture (5th generation GCN) and has 10 CUs (=640 shaders) clocked at up to 1300 MHz (Ryzen 7 2700U). The performance depends on the configured TDP (9-25 W at launch), the clocks, the cooling, and the memory configuration). The GPU should benefit 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.

AMD's reference design GPU is sitting between the GeForce 940MX / Radeon Pro 450 and GeForce MX150 / Radeon Pro 555. It can handle smooth gameplay in simple titles like League of Legends (med), Dota 2 (low), Overwatch (low), CS:GO (med), and Quake Champions (high) in 720p up to 1080p according to AMD.

Thanks to the 14nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics card can also be used for slim and light notebooks.

NVIDIA GeForce GTX 1070 (Desktop)

The Nvidia GeForce GTX 1070 is the second fastest Pascal based graphics card in mid May 2016. It is a high-end desktop graphics card. The mobile pendant is also called GeForce GTX 1070, but features more shaders and a lower core clock (see this page for details on the laptop version of the GTX 1070). Both cards are based on a cut down GP104 chip as the GTX 1080 and manufactured in 16 nm FinFET at TSMC. More details on the Pascal architecture including all features and comparisons to Maxwell, can be found here.

Compared to the GTX1080, the GTX1070 features less CUDA cores (1920 versus 2560) that are clocked a bit lower (maximum Boost 1683 versus 1733). Instead of the new GDDR5X, the GTX 1070 uses slower GDDR5 graphics memory - but still 8 GB. The TDP is also reduced from 180 Watt to 150 Watt.

The performance of the GTX 1070 is between the old GTX 980 Ti and the GTX 1080. Therefore, gaming in 4k at high details is possible with the card and also VR gaming is possible.

NVIDIA GeForce GTX 1080 Mobile

The Nvidia GeForce GTX 1080 for laptops (formerly known as GTX 1080M) is the mobile counterpart of the desktop GeForce GTX 1080. It uses the same GP104 chip and was officially announced at 16. August. The performance should be around +-10% of a non overclocked desktop GTX 1080. The amount of shaders and other technical specifications should be identical.

The mobile GTX1080 is the successor to the GeForce GTX 980 for Laptops and offers a significantly higher performance at the same TDP.

For thin and light laptops Nvidia offer a Max-Q called version of the GTX 1080 with lower TDP and also significantly lower performance. Sadly this variant im sold with the same GTX 1080 name, making it hard to judge the performance.

The performance depends on the used thermal headroom, processor and game. In our benchmarks the mobile GTX 1080 was between 0 to 10 percent slower than the desktop GTX 1080. Therefore, the card also allows gaming in 4k for modern and demanding games of 2017. However, the performance depends on the cooling and TDP settings in each laptop. E.g. the MSI GT73VR (200 W TDP) is much faster than the 1080 in the Razer Blade Pro (<=150 W).

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.

Due to the high TDP, the mobile GTX 1080 is only suited for large laptops with high performance cooling solutions. The power consumption is ranging from 150 to 200 Watt (according to Nvidia, up to 220 W in the Asus G701VIK, G800, GX800). A low power version (Max-Q) is available beginning summer 2017 with a reduced TGP of 90 - 110 Watt (at a reduced performance).
