The 3D performance lies between the Radeon R7 260X and R7 265X from AMD or between the GTX 750 and GTX 660 from Nvidia. The GeForce GTX 750 Ti is comparable to the Nvidia Geforce GTX 860M for laptops that features the same chip with slightly slower clock rates and therefore also performance. The GTX 750 Ti supports DirectX 11.2 but only feature level 11_0. Maxwell sets its focus on energy efficiency and was able to outperform the predecessor Kepler and AMD chips in similar performance regions. It is based on the first generation of the Maxwell architecture, namely the GM107 chip. The NVIDIA GeForce GTX 750 Ti is a mid-range desktop graphics card that was announced early 2014. NVIDIA GeForce GTX 750 Ti ► remove from comparison Therefore it is most suited for bigger laptops from 14-inch and up. The power consumption of the GeForce 945M should be somewhere around 40 Watt. 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. GM107 integrates the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. Therefore, it is most suited for medium details of demanding games in 2015 (see below for benchmarks).
The DDR3 variant of the GTX 950M is about 10 percent faster for example.
The performance of the 945M is slightly worse than the GTX 950M but clearly faster than the 940M. GM107 supports DirectX 12 with feature level 11_0 only. The increased size can handle some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing the performance. 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).Īnother optimization is the massively enlarged L2 cache (GM107: 2 MB). The dedicated DDR3 graphics memory is connected with a 128 Bit bus clocked at 1000 MHz (effective 2000, 32 GB/s).Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. The 945M offers 512 shaders (compared to the 640 of the GTX 950M) clocked at 928 MHz. The NVIDIA GeForce 945M is a mid-range, DirectX 12-compatible graphics card for laptops unveiled in March 2015. It is based on Nvidia's Maxwell architecture (GM107 chip) and manufactured in 28 nm. NVIDIA GeForce 945M ► remove from comparison
