NVIDIA GeForce GTX 960M vs NVIDIA Quadro M2000M vs NVIDIA Quadro M4000M

NVIDIA GeForce GTX 960M

The NVIDIA GeForce GTX 960M is an upper mid-range, DirectX 11-compatible graphics card for laptops unveiled in March 2015. It is based on Nvidia's Maxwell architecture (GM107 chip) and manufactured in 28 nm. The GTX 960M offers 640 shader units clocked at 1097 - 1202 MHz (Boost) as well as fast GDDR5 memory (128 bit, 5000 MHz effective, 80 GB/s).

Compared to the previous and technically very similar GTX 860M, the GTX 960M is clocked slightly higher.

Architecture

Compared to Kepler, Maxwell has been optimized in several details to increase power efficiency. Smaller Streaming Multiprocessors (SMM) with only 128 ALUs (Kepler: 192) and an optimized scheduler should lead to better utilization of the shaders. Nvidia promises that a Maxwell SMM with 128 ALUs can offer 90 percent of the performance of a Kepler SMX with 192 ALUs. GM107 features 5 SMMs and thus 640 shader cores, 40 TMUs and 16 ROPs (128-bit interface).

Another optimization is the massively enlarged L2 cache (GM107: 2 MB). The increased size can handle some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing the performance.

GM107 supports DirectX 12 with feature level 11_0 only.

Performance

Although the GTX 960M has the same memory bandwidth as the previous GTX 860M, its higher core clock leads to a slightly better performance. Overall, the 960M is almost 10 percent faster and similar to the desktop GTX 750 Ti.

Many games of 2014/2015 can be played fluently in FullHD resolution and high detail settings. However, very demanding games such as Assassin's Creed Unity will require lower resolutions and/or details.

Features

GM107 integrates the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. Of course, VP6 supports all features of previous generations (4K support, PIP, video encoding via NVENC API). Unfortunately, HDMI 2.0 is still not supported.

Power Consumption

The power consumption of the GeForce GTX 960M should be similar to the old GTX 860M (about 60 watts). Therefore, the GPU is best suited for 15-inch laptops or larger. The 900M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU.

NVIDIA Quadro M2000M

The 28 nm Nvidia Quadro M2000M is a mid-range DirectX 12 (FL 11_0) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a (first generation) Maxwell-based GPU built on the GM07 chip with 640 shader cores. Therefore, the GPU is similar to the consumer Nvidia GeForce GTX 960M or 950M. The Quadro M2000M is built for the Intel Skylake generation and is the successor to the Kepler-based Quadro K2100M. The M2000M typically comes with 4 GB GDDR5 VRAM clocked at 1250 MHz (5000 MHz effective at 80 GB/s compared to 48 GB/s on the K2100M). 

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.

Performance

As the exact clock speed of the M2000M is still not known, we can only speculate on the performance of the card. However, we do know that it is a mid-range model from the mobile 2015 Quadro line based on the same chip as the GeForce GTX 960M or 950M. Therefore, it should be faster than the old Quadro K2100M.

Using CUDA (Compute Capability 5.0) or OpenCL 1.2, the cores of the Quadro M2000M can be used for general calculations.

Power Consumption

The power consumption of the Quadro M2000M is rated for the same TGP of 55 Watt as the K2100M, including the board and memory components. Therefore, the card is suited for 15-inch notebooks and larger.

NVIDIA Quadro M4000M

The Nvidia Quadro M4000M is a high-end, DirectX 12 (FL_12_1) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a Maxwell-based GPU built on the GM204 chip with all 1280 of the 1536 shader cores activated and is manufactured in 28 nm at TSMC. Therefore, the GPU is similar to the consumer Nvidia GeForce GTX 970M. The Quadro M4000M is built for the Intel Skylake generation and is a successor to the Quadro K4100M (Kepler-based). The M4000M usually comes with 4 GB GDDR5 VRAM clocked at 1250 MHz (5000 MHz effective, 160 GB/s opposed to 102.4 GB/s of the K4100M). 

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.

Performance

The clock speeds of the Quadro M4000M are very similar to the GTX 970M based on the same chip. The base clock is slightly higher with 975 versus 924 MHz but the Boost speed is lower at 1013 versus 1038 MHz. Therefore, with good cooling the GTX 970M should be slightly faster. Compared to the Quadro line-up, it is the second fastest Quadro card in 2015 and therefore clearly faster than the old Quadro K4100M.

Using CUDA (Compute Capability 5.2) or OpenCL 1.2, the cores of the Quadro M4000M can be used for general calculations.

Power Consumption

The power consumption of the Quadro M4000M is rated at the same TGP of 100 Watt as the M5000M and older K5100M/K4100M (including the board and memory components). Therefore, the card is suited for large notebooks with 17-inch displays or greater.
