Aside from the improved polymorphic engine in the SSMs, it is also the first Nvidia chip to support DirectX 12 Feature Level 12_1. Furthermore, the L1 (96 KB per SMM) and L2 caches (2 MB) have been significantly increased to lower the needed bandwidth.Īlthough the GM107 and the GM204 both belong to the Maxwell generation, the newer and larger GM204 has several additional features and changes. Thanks to an improved compression algorithm, the connection to the GDDR5 memory should be significantly more efficient per MHz. The memory interface has a bandwidth of 128-bits (2x 64 bit). In addition, there are 32 ROPs in two clusters with 16 units each. As a result, only 1024 shader ALUs and 64 TMUs are active. But, in the GeForce GTX 965M, Nvidia have deactivated 8 of 16 SMMs. The GM204 features four GPCs, and each consists of four SMMs. Now each SMM contains only 128 shader units and 8 TMUs, which is noticeably less than an equivalent Kepler GPU. Among other changes, Nvidia have restructured the streaming multi processors (SMM) in order to increase workload and efficiency. Just like the mid-range GM107 chip ( GeForce GTX 860M), the GM204 is also based on Nvidia's new Maxwell architecture, which replaces the previous Kepler generation. In theory the GM206 also supports HDMI 2.0, but the laptop has to implement the wiring for this correctly. The TDP however should remain at 50 Watt like the GTX 960M and the chip is also pin compatible. This resulted in a 12% faster performance in games (in our tests with a MSI GE72 pre-sample in maximum detail settings). The clock rates specified by Nvidia are 924 MHz (+ Boost) for the GPU and 1250 MHz (5000 MHz effective) for the up to 4 GB of GDDR5 memory.Įarly 2015 a new version of the 965M (codename N16E-GR, formerly known as 965M Ti) based on the GM206 will be available that features higher core clocks of 935 MHz base and 1151 MHz Turbo. It was introduced in January 2015 and is based on the Maxwell GM204 (later GM206) architecture. The NVIDIA GeForce GTX 965M is a 28 nm DirectX-11 graphics card for mid- and high-end notebooks.
