NVIDIA Quadro K5100M vs Intel UHD Graphics Xe G4 48EUs vs Intel UHD Graphics 32EUs (Alder Lake)

NVIDIA Quadro K5100M

The NVIDIA Quadro K5100M is a high-end, DirectX 11 and OpenGL 4.3 compatible graphics card for mobile workstations. It is a Kepler-based GPU built on the GK104 chip with all 1536 shader cores activated and is manufactured in 28nm at TSMC. The Quadro K5100M is built for the Intel Shark Bay generation (Haswell) and as a successor to the Quadro K5000M (Chief River platform). As a new feature, PCIe 3.0 is supported for the first time. The K5100M usually comes with 8 GB GDDR5 VRAM clocked at 900 MHz (3600 MHz effective, 115.2 GB/s). 

The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD or DCC. OpenGL performance, for example, should be significantly better compared to GeForce graphics cards of similar specifications.

Architecture

The Kepler architecture is the successor to the Fermi architecture that first appeared in laptops with the GeForce 400M series. The GK104 Kepler core offers eight shader blocks, called SMX, that are clocked at the same speed as the central core. In the K5100M, all 8 blocks are active leading to the 1536 CUDA cores. Although more shader cores are available in the Kepler architecture as compared to the Fermi design, the Kepler shaders are still expected to be up to twice as power efficient. However, due to the missing hot clock of the shader domain, two shaders of a Kepler chip offer similar performance to just one shader of a Fermi chip (as the latter is clocked twice as fast).

Performance

The 3D gaming performance of the K5100M is clearly above the old Quadro K5000M, but about 10 percent below the slightly higher clocked GTX 780M. Nevertheless, most demanding games of 2013 will run fluently with maxed out details and very high resolutions.

Features

The improved feature set now includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840 x 2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. However, as most laptops will feature Optimus, the integrated GPU will likely have direct control over the display ports and may limit the feature set available by the Nvidia Kepler cards.

Using CUDA or OpenCL 1.2, the cores of the Quadro K5100M can be used for general calculations.

The 5th generation PureVideo HD video processor (VP5) is also integrated in the GK104 core and offers hardware decoding of HD videos. Common codecs such as MPEG-1/2, MPEG-4 ASP, H.264 and VC1/WMV9 are fully supported up to 4K resolutions while VC1 and MPEG-4 are supported up to 1080p. Two streams can be decoded in parallel for features such as Picture-in-Picture. Another novelty is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed by the NVENC API.

Power Consumption

The power consumption of the Quadro K5100M is rated at a TGP of 100 W including the board and memory components. Therefore, the card is suited for large notebooks with 17-inch displays or greater.

Intel UHD Graphics Xe G4 48EUs

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).
