AMD Radeon RX Vega 7 vs NVIDIA GeForce GTX 1050 Max-Q vs NVIDIA GeForce GTX 1080 Max-Q

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 1050 Max-Q

The Nvidia GeForce GTX 1050 with Max-Q design is a mainstream GPU based on the Pascal architecture and was announced in January 2018. Contrary to the faster models, the GTX 1050 uses the GP107 chip, which is manufactured in a 14 nm process at Samsung.

The clock is not the only difference compared to the regular GTX 1050 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

Features

The GP107 chip is manufactured in a 14 nm FinFET process at Samsung and offers a number of new features, including support for DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) as well as improved H.265 video de- and encoding (PlayReady 3.0). A full list of improvements and the new Pascal desktop GPUs is available in our dedicated Pascal architecture article.

Performance

The performance of the GeForce GTX 1050 Max-Q should be around 10-15 % below a regular GTX 1050 for laptops. This means the GPU is most suited for full HD gaming at high settings (not maximum).

Power Consumption

The power consumption of the GeForce GTX 1050 Max-Q is rated at 34 to 40 Watt and therefore significantly lower than the normal laptop GTX 1050 (53 Watt). Therefore, the Max-Q variant is also suited for thin and light laptops.

NVIDIA GeForce GTX 1080 Max-Q

The Nvidia GeForce GTX 1080 with the Max-Q design is a mobile high-end GPU from the Pascal series. It is designed for thin and light laptops and about 10-15% slower than a regular GTX 1080 for laptops based on the cooling capabilities. The base frequency (1101-1290 MHz) is also much lower than on the regular GTX 1080 (1566 MHz, at least -18%) and the Boost (1278-1458 MHz) is also much lower compared to 1733 MHz (at least -16%) for the regular GTX 1080. The memory clock, however, is identical.

The clock is not the only difference compared to the regular GTX 1080 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

The performance is nearer to the normal (Max-P) GeForce GTX 1070 than to then GTX 1080 (at least in the Asus Zephyrus). Therefore, most demanding games should be playable in full HD and maximum detail settings (see game benchmarks below).

Features

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 Max-Q design is notably lower than the normal GTX 1080 for laptops and ranges between 90 and 110 Watt (TGP) according to Nvidia.
