AMD Radeon RX Vega 7 vs NVIDIA GeForce MX250

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 MX250

The Nvidia GeForce MX250 is a dedicated entry-level mobile graphics card for laptops. It is based on the same Pascal GP108 chip as the predecessor, the GeForce MX150 / desktop GeForce GT 1030 but features increased clock speeds. As with the MX150, the MX250 is available in two versions, the normal 25 Watt version (1D13 device ID) and a low power version with 10 Watt TDP (1D25 device ID) and reduced performance (The MX150 with 10W had a 32% lower clock speed). The GDDR5 memory interface now also supports speeds up to 3.5 GHz = 7 GHz effective (up from 3 GHz).

The GP108 chip is manufactured in a 14 nm FinFET process at Samsung (LPP) and offers a number of new features, including support for DisplayPort 1.4 (ready), HDMI 2.0b, HDR and improved H.265 video de- and encoding (PlayReady 3.0). 4K HDR with Netflix however wont run due to the minimum 3 GB graphics memory that is required. Compared to the bigger Pascal chips, the small GP108 does not support Simultaneous Multi-Projection (SMP) for VR and G-Sync. A full list of improvements and the new Pascal desktop GPUs is available in our dedicated Pascal architecture article.

Thanks to the increased core speeds (up to +3% in Boost for the 25 Watt version, and faster memory speeds), the new MX250 should be slightly faster than the older MX150. First benchmarks indicate a 5% increase. Still modern should only run fluent in low settings (see the page of the MX150 for games and benchmarks).
