NVIDIA GeForce 920MX vs Intel HD Graphics 505 vs Intel HD Graphics 510

NVIDIA GeForce 920MX

The Nvidia GeForce 920MX is an entry-level graphics card for laptops that was launched in the first quarter of 2016. In comparison to the older 920M, the 920MX is now be based on the modern Maxwell chip of the 930MX but with a reduced shader count of 265 (GM108). According to our sources the TDP of 5-12 Watt and the support for DDR3 and GDDR5 is also specified.

The performance depends on the used graphics memory. The DDR3 version was slightly slower than an average GeForce 930M in our tests (and definitely faster than the GeForce 920M). The GDDR5 version could therefore best the 930M slightly. However, both versions are not suited for demanding games of 2017. Less demanding games, like The Sims 4, should be playable in medium to high settings (see below for benchmarks).

Thanks to the low power consumption, the GeForce 920MX is also suited for thin and light laptops.

Intel HD Graphics 505

The Intel HD Graphics 505 is an integrated processor graphics unit from the Apollo Lake generation (e. g. Pentium N4200), which was announced mid 2016. The GPU can convince with low consumption figures, but the performance is only in the low-end segment and is rarely sufficient for modern games. Being the maximum configuration of the Apollo Lake GPU, the HD Graphics 505 is equipped with 18 Execution Units (EUs) running at up to 750 MHz. The technical specifications of the GPU are based on Intel's Gen9 architecture, which is also used for the more expensive Skylake series.

Due to its lack of dedicated graphics memory or eDRAM cache, the HD 505 has to access the main memory via processor (2x 64bit DDR3L-/LPDDR3-1866, LPDDR4-2400).

Performance

The HD Graphics 505 should be slightly slower than the older Core-M GPU HD Graphics 5300, so modern games (as of 2016) will rarely run smoothly even at the lowest settings.

Features

The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Up to three displays can be connected via DP/eDP or HDMI (4K probably only at 30 Hz via HDMI 1.4).

Power Consumption

The TDP of the whole Pentium N4200 chip is 6 Watts by default, so the GPU is primarily used for (often passively cooled) netbooks or thin notebooks. The TDP can also be reduced to 4 Watts, but this will obviously affect the performance.

Intel HD Graphics 510

The Intel HD Graphics 510 (GT1) is an integrated graphics unit, which can be found in low-end ULV (Ultra Low Voltage) processors of the Skylake generation. This "GT1" version of the Skylake GPU offers 12 Execution Units (EUs) clocked at up to 950 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 510 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

Depending on various factors like memory configuration, the HD Graphics 510 should perform sligthly below the older HD Graphics 4400 and will handle modern games (as of 2015) only in lowest settings (if it does at all).

Features

The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Displays can be connected via DP 1.2 / eDP 1.3 (max. 3840 x 2160 @ 60 Hz), whereas HDMI is limited to the older version 1.4a (max. 3840 x 2160 @ 30 Hz). However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously.

Power Consumption

The HD Graphics 510 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.
