NVIDIA Quadro RTX 4000 (Laptop) vs NVIDIA Quadro K3000M vs NVIDIA T1000

NVIDIA Quadro RTX 4000 (Laptop)

NVIDIA Quadro K3000M

The NVIDIA Quadro K3000M is a performance-class, DirectX 11.1-compatible graphics card for mobile workstations. It is a Kepler-based GPU built on the GK104 chip (but using only 576 shader cores) and is manufactured in 28nm at TSMC. The Quadro K3000M is built for the Intel Chief River generation (Ivy Bridge) and is the successor to the Fermi-based Quadro 3000M (Huron River platform).

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 than 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 K3000M, 3 blocks are active leading to the 576 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 provide similar performance to just one shader of a Fermi chip (as the latter is clocked twice as fast). 

PCIe 3.0 is now supported by the mobile Kepler series and an optional Turbo mode can automatically overclock the Nvidia card by a theoretical 15 percent if the laptop cooling system allows it. The implementation of this boost mode is done in the BIOS, but it is ultimately dependent upon the manufacturer of the laptop.

Performance

The performance is slightly above the older Quadro 4000M based on the fermi architecture. Compared to consumer cards, the K3000M performs similar to the GeForce GT 750M. Games of 2013 can be played fluently in medium or high detail and resolution settings.

Features

The improved feature set now includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840x2160 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.

The 5th generation PureVideo HD video processor (VP5) is also integrated in the GK107 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.

The power consumption of the K3000M is rated at 75 Watt (TGP according to Nvidia) and is therefore suited for medium-sized notebooks 17-inches or greater.

NVIDIA T1000

The Nvidia T1000 is a professional desktop graphics card for small entry-level workstations. It is based on the same TU117 Turing chip as the consumer GeForce GTX1650. The number of shader units is also identical at 896. With 8 GB VRAM, the Nvidia T1000 however offers more VRAM, which is still connected via a 128 bit memory bus. The power consumption of the Nvidia T1000 is only rated at 50 watts and therefore does not require an additional power connection.

The professional graphics cards offer certified drivers which are optimized for stability and performance in professional applications (CAD, DCC, medical, prospecting, visualization applications). As a result, the performance in these areas is significantly better compared to consumer graphics cards with the same chip.

In contrast to the more powerful RTX cards (e.g. Quadro RTX 3000), they do not offer ray tracing and tensor cores. The Turing architecture has also seen significant improvements at the CUDA core level. Float and INT operations can now be executed simultaneously, the cache has been standardized and improved and adaptive shading has been introduced. As a result, Nvidia claims up to 50% higher performance per core compared to Pascal.
