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. The 930M should feature the full GM108 with 3 SMMs (384 shader cores, 24 TMUs, and 8 ROPs due to the 64-bit interface).Īnother optimization is the massively enlarged L2 cache. Later in 2016, the successor named GeForce 930MX was released that was available with GDDR5.Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. Update: The N16S-LP variant (5-12 Watt TDP, Low Power version?) will be available with GDDR5 starting in the first quarter of 2016.
As the LP version is clocked only at 457 MHz + Boost it may feature more shaders (or a high Boost). The shader count for these low power 930M are also unknown. The performance of the GDDR5 version is still unknown.
The DDR3 variant should be approximately 10% slower than the 25 Watt version. In addition to the "normal" 25 Watt 930M, there is also a low power variant with a TDP of 12 Watt and support for DDR3 and GDDR5. It is based on the last years GeForce 840M. The NVIDIA GeForce 930M (sometimes also called Nvidia GeForce GT 930M) is a (lower) mid-range, DirectX 11-compatible graphics card for laptops unveiled in March 2015. NVIDIA GeForce 930M ► remove from comparison The HD Graphics 4400 can be found on ULV dual-core Haswell models with a TDP of 15 watts. Depending on the clock rate, the HD 4400 matches the performance of a dedicated Radeon HD 7550M.ĭue to the 22nm 3D Tri-Gate production process, the power consumption is relatively low. Compared to the ULV versions of the Ivy Bridge HD 4000, the HD 4400 is about 20 - 30 percent faster. This performance boost is achieved by architectural improvements and an increased number of execution units: The GT2 version integrates 20 EUs, compared to 16 EUs for the old HD 4000. Furthermore, the reduced TDP limits the Turbo Boost. Therefore, the clock rates are relatively low. The performance of the HD Graphics 4400 is somewhat below the HD 4600, since the GPU is designed for ULV models. Compared to the faster 4600, the 4400 offers the same amount of shaders, but lower clock speeds (see table of clock speeds of the different CPU models below). It also features an improved decoder for 4K videos and the fast Quick Sync encoder. The GPU now supports DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. In comparison to the HD 4000, the HD 4400 graphics core has been modified extensively. Depending on the processor model, the turbo clock rates may differ, resulting in varying graphics performance between models. The Intel HD Graphics 4400 (GT2) is a processor graphics card included in some of the ULV Haswell processors of 2013. The relatively low base clock can be automatically overclocked using Turbo Boost technology. Intel HD Graphics 4400 ► remove from comparison
