The larger size can process some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing 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). In addition, there is a slightly higher clocked version (936 MHz + Boost) using slower DDR3 memory (2000 MHz effective).Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. The GTX 850M offers 640 shader units clocked at 876 MHz (+ Boost) as well as 4 GB of GDDR5 memory (128 bit, 5000 MHz effective). The NVIDIA GeForce GTX 850M is an upper 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 (GM107 chip), but is still manufactured in 28 nm. 3D Printing, 5G, Accessory, AI, Alder Lake, AMD, Android, Apple, ARM, Audio, Benchmark, Biotech, Business, Camera, Cannon Lake, Cezanne (Zen 3), Charts, Chinese Tech, Chromebook, Coffee Lake, Comet Lake, Console, Convertible / 2-in-1, Cryptocurrency, Cyberlaw, Deal, Desktop, E-Mobility, Education, Exclusive, Fail, Foldable, Gadget, Galaxy Note, Galaxy S, Gamecheck, Gaming, Geforce, Google Pixel, GPU, How To, Ice Lake, Intel, Intel Evo, Internet of Things (IoT), iOS, iPad, iPad Pro, iPhone, Jasper Lake, Lakefield, Laptop, Launch, Leaks / Rumors, Linux / Unix, List, Lucienne (Zen 2), MacBook, Mini PC, Monitor, MSI, OnePlus, Opinion, Phablet, Radeon, Raptor Lake, Renoir, Review Snippet, Rocket Lake, Ryzen (Zen), Science, Security, Single-Board Computer (SBC), Smart Home, Smartphone, Smartwatch, Software, Storage, Tablet, ThinkPad, Thunderbolt, Tiger Lake, Touchscreen, Ultrabook, Virtual Reality (VR) / Augmented Reality (AR), Wearable, Wi-Fi 7, Windows, Workstation, XPS, Zen 3 (Vermeer), Zen 4
