Similar to GM107, the GM108 supports DirectX 12 with Feature Level 11_0 only. The larger size can process some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing performance.
#Nvidia geforce gt 930m with 2gb ram full
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. Palit has three GT 1030 cards on sale (tabulated above) differentiated by a single digit in a 17-character product code, though its passive cooled (GDDR5) model is clearly labelled as a 'KalmX' model.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. While Gigabyte and MSI at least flag up the use of DDR4 in their graphics card names the same can't be said for Palit which put out a press release describing its GeForce GT 1030 as coming equipped with 2GB of GDDR5. MSI's GeForce GT 1030 2GD4 LP OC specs page at least reveal one benefit to moving from GDDR5 to DDR4: the peak power consumption is reduced significantly, from 30W to 20W. This would further impact any expected performance level a casual GPU buyer might have. However graphics cards such as the MSI GeForce GT 1030 2GD4 LP OC with their 2GB of DDR4 RAM and a memory clock of 2.1GHz can only deliver approximately a third of that headline reference memory bandwidth.Ī comparison of two sister GT 1030 cards (both designated 'LP OC' - low profile overclocked) from MSI (as pictured above) reveals that the DDR4 cards also suffer from slower core clocks, and the same is true for Gigabyte's low profile GT 1030 siblings. This provides memory bandwidth of 48GB/s. As uncovered by Tom's Hardware, the MSI GT 1030 2GD4 LP OC, Gigabyte GT 1030 Low Profile D4 2G, and Palit GeForce GT 1030, all come with DDR4 RAM on board rather than GDDR5 memory.Ī reference GT 1030 employs 2GB of GDDR5 RAM at a speed of 3GHz, doubled up to deliver and effective 6GHz, on a 64-bit memory bus. Several well known AIB brands have quietly released graphics cards which differ rather strikingly from Nvidia GeForce GT 1030 reference card specs.
