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 830M features a partially deactivated GM108 with just 2 out of 3 SMMs (256 shader cores, 16 TMUs, 8 ROPs, 64-bit interface).Īnother optimization is the massively enlarged L2 cache. The 830M offers 256 shader units clocked at 1029 MHz (+ Boost) as well as 2 GB of DDR3 memory (64 bit, 2000 MHz effective).Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. The NVIDIA GeForce 830M is a (lower) mid-range, DirectX 12-compatible graphics card for laptops unveiled in March 2014. It is one of the first cards based on Nvidia's new Maxwell architecture (GM108 chip), but is still manufactured in 28 nm. NVIDIA GeForce 830M ► remove from comparison
