![]() ![]() GM107 supports CUDA Compute Capability 5.0 compared to 3.5 on GK110/GK208 GPUs and 3.0 on GK10x GPUs. Also, each Graphics Processing Cluster, or GPC, contains up to 4 SMX units in Kepler, and up to 5 SMM units in first generation Maxwell. Nvidia claims a 128 CUDA core SMM has 86% of the performance of a 192 CUDA core SMX. ![]() SMM allows for a finer-grain allocation of resources than SMX, saving power when the workload isn't optimal for shared resources. Texture units and FP64 CUDA cores are still shared. These units are connected by a crossbar that uses power to allow the resources to be shared. This is in contrast to Kepler, where each SMX has 4 schedulers that schedule to a shared pool of 6 sets of 32 FP32 CUDA cores, 2 sets of 16 load/store units, and 2 sets of 16 special function units. The layout of SMM units is partitioned so that each of the 4 warp schedulers in an SMM controls 1 set of 32 FP32 CUDA cores, 1 set of 8 load/store units, and 1 set of 8 special function units. The structure of the warp scheduler is inherited from Kepler, which allows each scheduler to issue up to two instructions that are independent from each other and are in order from the same warp. Nvidia also changed the streaming multiprocessor design from that of Kepler (SMX), naming it SMM. Accordingly, Nvidia cut the memory bus from 192 bit on GK106 to 128 bit on GM107, further saving power. Nvidia increased the amount of L2 cache from 256 KiB on GK107 to 2 MiB on GM107, reducing the memory bandwidth needed. These new chips provide few consumer-facing additional features Nvidia instead focused on power efficiency. List of supported graphics and general-purpose computing APIs, including their specific versions.Main article: Maxwell (microarchitecture) First generation Maxwell (GM10x) įirst generation Maxwell GM107/GM108 were released as GeForce GTX 745, GTX 750/750 Ti and GTX 850M/860M (GM107) and GT 830M/840M (GM108). ![]() This information will prove useful if you need some particular technology for your purposes. ![]() OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). Types and number of video connectors present on the reviewed GPUs. Integrated GPUs have no dedicated VRAM and use a shared part of system RAM. Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard. Useful when choosing a future computer configuration or upgrading an existing one. Information on Quadro M3000M and GeForce GTX 960M compatibility with other computer components. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. ![]()
