Due to its lack of dedicated graphics memory or eDRAM cache, the HD 620 has to access the main memory (2x 64bit DDR3/DDR4). 1.050 MHz) and offer a comparable performance. It is clocked with up to 1.150 MHz and therefore 100 MHz higher than the old HD Graphics 620 (max. Compared to the similar named Intel HD Graphics 620 in the 2016 Kaby Lake CPUs, only the name changed from HD to UHD. I don't know if it's of any importance but C++ AMP, for instance, recognizes Intel HD Graphics card well, but not the Radeon.The Intel UHD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake Refresh generation (8th generation Core). The reasons I didn't use the second advices are it's not my computer they were talking about and as far as I know there exists quite a number of problems with installing AMD drivers on Windows (Win 8.1 in particular) and especially on laptops with switchable graphics like mine (by the way I have never tried switchable thing out, so I don't know if it works).Īnyway I would like to use OpenCL on this computer, so if anyone has some knowledge, please share it with me. BrightSide, but I assume they should have tested it) I have been studying this problem for a week already and found some direct statements that it IS possible to use OpenCL on my Radeon card: I linked to the the libs residing in AMDAPPSDKROOT directory and included respective headers.īut the following code crashes (see GPU-Z error):Ĭl_int ret = clGetPlatformIDs(0,0,&n_plats) But on startup it emerges a message, saying that OpenCL lib call crashed while attempting to get OpenCL support info.
GPU-Z tells me that I have both, but no OpenCL support on either of the devices. It simply stated that I only have the Intel HD Graphics. According to it both devices' drivers are 8.9 from AMD.įurMark didn't even recognize my dicrete card.
The device manager recognizes both devices correctly (from the first glance). Hardware: AMD Radeon HD 7670m Intel HD Graphics 4000 Intel Core i5 CPU īIOS info: InsydeH20 Setup Utility Rev. Laptop: HP Envy m6-1153er, Windows 8.1 64 bit According to all the utilities I've tried I have no OpenCL support (and sometimes don't even have my discrete card), although I know that it should have, at least early versions. Now I'm trying to use OpenCL on my laptop. Hello! I work and study in CAE/mathematical modeling field.
