Intel HD Graphics 500 vs Intel HD Graphics 520 vs Intel HD Graphics 515

Intel HD Graphics 500

The Intel HD Graphics 500 is an integrated processor graphics unit from the Apollo Lake generation (e. g. Celeron N3450 and Celeron N3350), 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 a partial configuration of the Apollo Lake GPU, the HD Graphics 505 is equipped with just 12 Execution Units (EUs) (HD Graphics 505: 18 EUs) running at up to 650-700 MHz depending on the model. 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 Broadwell GPU HD Graphics (Broadwell), 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 520

The Intel HD Graphics 520 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Skylake generation. This "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 520 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

The exact performance of the HD Graphics 520 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model. The fastest versions (Core i7-6600U) should perform similar to a dedicated GeForce 820M and will handle modern games (as of 2015) in low settings.

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

Intel HD Graphics 515

The Intel HD Graphics 515 (GT2) is a low-end integrated graphics unit, which can be found in the Core m-series of the Skylake generation. This "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1000 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 515 has to access the main memory (2x 64bit DDR3L-1600 / LPDDR3-1866).

Performance

According to Intel, the HD Graphics 515 is up to 41 percent faster than the previous HD Graphics 5300 (Broadwell). Nevertheless, the GPU will handle only simple games like Counter-Strike or Dota with decent frame rates. Depending on the specific CPU model, memory configuration and TDP (4.5 W, configurable), performance may vary substantially.

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 515 can be found in Core m processors with 4.5 W TDP (3.5/3.8 W cTDP down, 7 W cTDP up) and is therefore suited for very thin, mostly passively cooled 2-in-1 notebooks and tablets.
