Intel UHD Graphics 32EUs (Alder Lake) vs Intel HD Graphics (Braswell)

Intel UHD Graphics 32EUs (Alder Lake)

Die Intel Xe Graphics 32 EUS (Alder Lake) ist eine Prozessorgrafikkarte, die Anfang 2023 vorgestellt wurde. Sie basiert auf die Xe Architektur (Gen12) und bietet in Alder Lake CPUs nur 32 der 96 verbauten Execution Units (EUs). Die GPU wird im verbesserten 10nm Verfahren (Intel 7) bei Intel gefertigt. Die Rohleistung ist vergleichbar mit der Radeon RX Vega 6 (in Ryzen 5000 CPUs), jedoch ist die Spieleleistung geringer durch den schwächeren Treibersupport (in 2022). Nur anspruchslose Spiele wie Dota 2 Reborn sind mit geringsten Settings flüssig spielbar (siehe unten).

Intel HD Graphics (Braswell)

The Intel HD Graphics (Braswell)  is an integrated graphics card in the low end SoCs of the Braswell series (e.g. Pentium N3700). 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 performance depends on the processor. The fastest models offer 16 EUs (shader cores) at 400 - 700 MHz. It should be about twice as fast as the old HD Graphics in Bay Trail SoCs. At the time of announcement in Q1 2015 the following models exist:

• Pentium N3700: 16 EUs @ 400 - 700 MHz, Dual-Channel Memory
• Celeron N3150: 12 EUs @ 320 - 640 MHz, Dual-Channel Memory
• Celeron N3050: 12 EUs @ 320 - 600 MHz, Dual-Channel Memory
• Celeron N3000: 12 EUs @ 320 - 600 MHz, Dual-Channel Memory

In the first CPUs the graphics card was only called Intel HD Graphics. Later (e.g. in the Celeron N3060) Intel renamed it to Intel HD Graphics 400 (Celeron with 12 EUs) and Intel HD Graphics 405 (Pentium with 16 EUs).

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.
