GeForce 310M) and AMD ( HD 5450). In comparison with AMD's APU models, the HD 3000 can only compete against the C-and E-series, but not the faster Llano and Trinity models. Our performance tests with the high clocked mainstream version of the HD Graphics 3000 in quad-core processors showed a performance level on par with older entry level generations from NVIDIA (e.g. OpenCL is not supported (the media SDK only uses the CPU). The EUs can be accessed using DirectX 10.1, OpenGL 3.0 and DirectCompute 4.1. The slower HD Graphics 2000 uses only 6 Execution Units. The HD 3000 offers 12 Execution Units (EUs) like the old Intel GMA HD but due to architectural changes each EU is now faster.
Mainstream and high-end Dual und Quad-Core Core ix-2xx0 (base 650MHz, Turbo 1100-1300MHz).LV processors Core ix-2xx5 (base 500MHz, Turbo 1000MHz).ULV processors Core ix-2xx7 (base 350MHz, Turbo 900-1000MHz).The base speed and the turbo boost speed of the HD Graphics 3000 depend on the processor: Due to TurboBoost, the GPU can be overclocked depending on the current CPU load and power consumption. The Intel HD Graphics 3000 (or Intel Graphics Media Accelerator HD 3000, GMA HD 3000, Intel HD Graphics 200) is an integrated graphics card in the Sandy Bridge codenamed processors. The HD Graphics 3000 has no dedicated memory but shares the Level 3 / LLC Cache with the CPU cores and also part of the main memory. Intel HD Graphics 3000 ► remove from comparison
The 800M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU. Therefore, the 860M is best suited for 15-inch laptops or larger. The low-clocked Kepler version draws just slightly more power. The power consumption of the GeForce GTX 860M should be similar to the old GTX 765M (about 60 watts).
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. However, very demanding games such as Crysis 3 or Battlefield 4 will require lower resolutions and/or details.ĭespite its considerably higher shader count, the Kepler version is about 10 percent slower, mainly due to the worse bandwidth efficiency. Similar to Fermi and Kepler, Maxwell / GM107 supports DirectX 11.2 with feature level 11.0 only.Īlthough the GTX 860M has much less memory bandwidth and computing power, it can compete with (or sometimes even beat) the old Kepler-based GeForce GTX 770M while drawing significantly less power. Many games of 2013/2014 (Tomb Raider or BioShock Infinite, etc.) can be played fluently in FullHD resolution and very high detail settings. 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 GTX 860M offers 640 shader units clocked at 1029 MHz (+ Boost) as well as 4 GB of GDDR5 memory (128 bit, 5000 MHz effective).Īlternatively, there is also a version based on the Kepler chip GK104, which has 1152 shader units clocked at 797 MHz.Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. The NVIDIA GeForce GTX 860M 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. NVIDIA GeForce GTX 860M ► remove from comparison
