Intel HD Graphics P530 vs NVIDIA GeForce RTX 3090 Ti vs Intel HD Graphics (Sandy Bridge)

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 3090 Ti

The Nvidia GeForce RTX 3090 Ti is a high-end desktop graphics card based on the Ampere generation. It was announced early 2022 the fastest desktop gaming graphics card.

It uses the big GA102 chip and offers 10,752 shaders and 24 GB GDDR6X graphics memory. The RTX3090ti is rated at 450 Watt.

Intel HD Graphics (Sandy Bridge)

The Intel HD Graphics (Family) is a processor graphics card which is integrated in the cheap Celeron and Pentium model of the Sandy Bridge generation. It is similar to the Intel HD Graphics 2000 and not with the processor graphics of the older Arrandale dual-core processors (which bears the same name). 

Depending on the processor, the HD graphics offers a different base and Turbo Boost clock speed. Currently there are three different models:

• Power Saving e.g. Celeron 847: base 350MHz, Turbo 800MHz
• Celeron e.g. Celeron B810: base 650MHz, Turbo 950MHz
• Pentium e.g. Pentium B950: base 650MHz, Turbo 1100MHz

Furthermore, the slow CPU performance of some models may influence the games a lot. For example, although the GPU in the Celeron B710 differs not much from the Pentium B950, the gaming performance was clearly worse and many games were unplayable.

As the Intel HD Graphics 3000 and 2000, the processor graphics card is able to use part of the last level cache of the processor (2MB usually for the entry level CPUs). This could be seen as a small amount of very fast dedicated memory.

Altought 2x Antialiasing (AA) is supported, the chip is as fast as when rendering 4x AA. In the Unigine Valley benchmark a similar HD 3000 i7-2637M for example reached the same score with 2x AA and 4x AA.

The feature set compared to the HD Graphics 3000 is also reduced in these entry level CPUs. E.g. Intel Quick Sync (for de- and encoding of HD videos), In Tru 3D, Clear Video HD are usually deactivated.
