The Nvidia Quadro M3000M 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 1024 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 965M. The Quadro M3000M is built for the Intel Skylake generation and is a successor to the Quadro K3100M (Kepler-based). The M3000M 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 K5100M).
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 M3000M is still not known, we can only speculate on the performance of the card. However, it is the mid-range model of the mobile Quadro line in 2015 and based on the same chip as the GeForce GTX 965M. Therefore, it should be clearly faster than the old Quadro K3100M.
Using CUDA (Compute Capability 5.2) or OpenCL 1.2, the cores of the Quadro M3000M can be used for general calculations.
Power Consumption
The power consumption of the Quadro M3000M is rated at the same TGP of 75 Watt as the K3100M (including the board and memory components). Therefore, the card is suited for large notebooks with 17-inch displays or greater and 25 Watt less than the M4000M and M5000M.
The NVIDIA GeForce GTX 965M SLI is a high-end DirectX 11-compatible graphics solution for laptops, consisting of two GeForce GTX 965M. Each card has a 28 nm GM204 GPU based on the Maxwell architecture, which is the same chip as found on the GTX 980M, GTX 970M as well as several desktop cards. The clocks for the SLI-setup are usually identical to a single GTX 965M (924 MHz GPU, 1250 MHz memory).
With SLI, each card renders a single frame (AFR mode). Therefore, it may suffer from micro stuttering in low fps ranges of 30 fps. This happens because of different timespans between two frames (e.g., irregular delays between sequential frames).
Architecture
GM204 is based on Nvidia's Maxwell architecture, which replaces the previous Kepler generation. Among other changes, Nvidia have restructured the streaming multi processors (SMM) in order to increase workload and efficiency. Now each SMM contains only 128 shader units and 8 TMUs, which is noticeably less than an equivalent Kepler GPU. The GM204 features four GPCs, and each consists of four SMMs. But, in the GeForce GTX 965M, Nvidia have deactivated 8 of 16 SMMs. As a result, only 1024 shader ALUs and 64 TMUs are active. In addition, there are 32 ROPs in two clusters with 16 units each.
The memory interface has a bandwidth of 128-bits (2x 64 bit) for each of the two GPUs. Thanks to an improved compression algorithm, the connection to the GDDR5 memory should be significantly more efficient per MHz. Furthermore, the L1 (96 KB per SMM) and L2 caches (2 MB) have been significantly increased to lower the needed bandwidth. Compared to the mid-range GM107, the newer and larger GM204 has several additional features and changes. Aside from the improved polymorphic engine in the SSMs, it is also the first Nvidia chip to support DirectX 12 Feature Level 12_1.
Performance
With good driver support, SLI almost doubles the performance of a single card. In this case, the GTX 965M SLI beats a single GeForce GTX 980M by about 10 percent. Therefore, the GTX 965M SLI is powerful enough to run even the most demanding games with highest details, AA/AF and/or resolutions exceeding FullHD.
Features
Most of the features are identical to the GeForce GTX 800M series. With the GTX 965M, there can be up to 4 active displays, but this will likely decrease due to Optimus. Displays can be connected with a maximum resolution of 3840 x 2160 pixels via DisplayPort 1.2 or HDMI 2.0 (no HDCP @ 4K). HD audio formats like Dolby True HD and DTS HD can be sent to a compatible receiver as bitstream. As with previous models, 3D Vision is not supported with Optimus.
The video processor VP6 supports the usual formats like H.264 and can also decode and encode H.265 with a resolution of up to 4K via the NVENC API (hybrid H.265 decoder, not fully fixed function). Several parallel streams, such as picture-in-picture in a Blu-Ray movie, are also possible.
Further features of the GTX 900M series, which are also partly supported by older cards, include Battery Boost (longer battery life during gaming), Shadowplay (recording of gaming videos up to 4K60p and 130 Mbit/s) and Gamestream (game streaming on Shield console). More information on these features are available here.
Power Consumption
The power consumption of each GeForce GTX 965M including its MXM board and memory should be around 70 W, leading to a total TDP of about 140 W. Therefore, the SLI setup can only be used in very large and heavy gaming notebooks with powerful cooling systems. Under low load, dynamic clock rates help the GPUs to save energy.
