Intel HD Graphics P530 vs NVIDIA GeForce RTX 3080 12 GB vs Intel HD Graphics 405 (Braswell)

Intel HD Graphics P530

The Intel HD Graphics P530 (GT2) is an integrated graphics unit, which can be found in various Xeon workstation processors of the Skylake generation. The "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 P530 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

Depending on the memory configuration, the HD Graphics P530 is just slightly behind a dedicated GeForce 920M and will handle modern games (as of 2015) in low or medium 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 P530 can be found in mobile quad-core Xeon processors with 45 W TDP.

NVIDIA GeForce RTX 3080 12 GB

The Nvidia GeForce RTX 3080 12GB is high-end desktop graphics card based on the Ampere generation. It uses the big GA102 chip and offers 8,704 shaders and 12 GB GDDR6X graphics memory. Compared to the older 10 GB model, the 12 GB model offers more bandwidth and therefore a higher TDP.

The gaming performance in 4k is clearly better than the old GeForce RTX 2080 Ti (approximately 15% faster). Therefore, even demanding games should run with maximum detail settings in 4k. Enabling raytracing will however reduce the framerate and therefore maximum details won't be playable. 

The RTX3080 is produced in 8nm at Samsung and rated at 350 Watt.

Intel HD Graphics 405 (Braswell)

The Intel HD Graphics 405 (Braswell)  is an integrated graphics card in the low end SoCs of the Braswell series (e.g. Pentium N3710). It is based on the same architecture as the integrated GPU of the Broadwell graphics cards (e.g. HD Graphics 5300), but offers less shader cores and slower clock speeds.

The GPU was simply called Intel HD Graphics (Broadwell) before 2016 and included also the slower 12 EUs version in the Celeron model. The Graphics 405 name currently only stands for 16-core-versions in Pentium models. The 12 EU version is now called Intel HD Graphics 400.

The clock speed and memory configuration can still vary from model to model.

Gaming performance ist still only suited for older or less demanding games. Often also the processor is limited gaming performance (e.g. in the dual-core N3000).

The SoC also integrates a video decoding engine that should be able to handle 4K H.265 videos.
