NVIDIA GeForce MX230 vs Intel Iris Plus Graphics 655 vs Intel HD Graphics 630

NVIDIA GeForce MX230

The Nvidia GeForce MX230 is an entry-level dedicated  laptop graphics card with DirectX 12 support (FL 12_1) based (most likely) on the Pascal architecture (and not Maxwell as the older MX130). Similar to the faster MX250, the MX230 is based on the GP108 chip.

Features

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.

Performance

Thanks to the newer Pascal architecture, the MX230 is significantly faster than the old GeForce MX130 (Maxwell based). Demanding games of 2019 run only in lowest resolution and detail settings and may stutter (e.g. Anno 1800 or Rage 2 ran with under 30fps in our benchmarks). Less demanding games like Overwatch, Fifa 19 or Rocket League, however, can be played in higher detail and resolution settings without stuttering (see benchmarks below).

Power Consumption

The MX230 is manufactured in 14nm at Samsung and due to the low shader count and 64 Bit memory bus, the power consumption is rather low. Therefore, the chip can be also used for small and thin laptops. In our power tests, the faster MX250 needed 22% more power (Furmark load) and the old MX130 even 38% more. The integrated UHD Graphics 620 needed on average only 17% less power at a much lower performance.

Intel Iris Plus Graphics 655

Intel HD Graphics 630

The Intel HD Graphics 630 (GT2) is an integrated graphics card, which can be found in various desktop and notebook processors of the Kaby-Lake generation (Kaby-Lake-H quad-core chip). The "GT2" version of the GPU offers 24 Execution Units (EUs) and the clocks depend on the CPU model. Due to its lack of dedicated graphics memory or eDRAM cache, the HD 630 has to access the main memory (2x 64-bit DDR3L-1600 / DDR4-2133).

Performance

The exact performance of the HD Graphics 630 depends on various factors like TDP, L3 Cache, memory (DDR3/DDR4) and maximum clock rate of the specific model. However, it should be fairly similar to the HD Graphics 530 (see for gaming benchmarks) and therefore only suited for low demanding games like Overwatch or Farming Simulator 2017 (low details).

Features

The revised video engine in the Kaby Lake chips now supports H.265/HEVC Main10 profile at 10-bit color depth and also the VP9 codec in hardware. Furthermore, HDCP 2.2 is also supported in all chips, which allows Netflix 4K videos, for instance. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The HD Graphics 630 can be found in several notebook and desktop processors of different TDP classes (35 - 91 W). Thanks to the improved 14nm+ process, the power consumption could be slightly lower compared to Skylake CPUs.
