The graphics processor for AMD Radeon HD 8750M laptops is made at 28 nm. technology, which allowed the manufacturer to place more than one and a half times more transistors on a single chip with a smaller area compared to previous models built on the old VLIW5 architecture. The mobile video adapter AMD Radeon HD 8750M fully supports DirectX 11.1 and Shader 5.0, we also note that the new GPU received 384 stream processors, 24 texture units and 8 rasterization units, and the operating core frequencies are 620-775 MHz.
The maximum volume of its own video memory of a new video card can reach 2 GB, and its standard can be either DDR3 or GDDR5. The advantages of the new mobile GPU from AMD include increased energy efficiency, in particular, achieved by the ZeroCore function, which almost completely cuts off power to unused cores, and the PowerTune function, which increases the clock speed when possible and necessary. As for the performance of the AMD Radeon HD 8750M, it will most likely be about the same as that of the video card from the competing company GeForce GT 640M.
Supported technologies
you PowerTune – a calculator that calculates the power consumption of the card in real time at intervals of milliseconds based on the analysis of the task being performed (without any analog sensors). And if possible, the GPU clock speed increases. Note that this is not a reset of the frequency relative to the nominal when the power threshold is reached, but, on the contrary, a precisely verified dynamic acceleration.
ATI PowerPlay Is a dynamic power management technology used in some graphics processing units (GPUs) manufactured by AMD (formerly ATI). The principle of operation is based on tracking the GPU load, determining the optimal parameters and correspondingly changing the clock frequency of the chip, memory and supply voltage, thereby optimizing the power consumption and heat dissipation of the video card. The technology in idle modes can disable unused GPU blocks.
ATI Eyefinity — a technology developed by the American company AMD that allows multiple displays to be connected together to a personal computer. ATI Eyefinity assumes connection from one to six displays inclusive to one graphics card. Desktop duplication and stretching modes are supported across multiple monitors, and a special new feature allows displays to be grouped into one large screen that can display a PC desktop or, for example, video, as well as windowed or full-screen 3D applications.
AMD HD3D — The technology is supported by an extended and open ecosystem that, when combined with specific AMD hardware and software technologies, enables the 3D viewing of many applications and processes on the PC.
AMD Enduro — Automatically disables AMD Radeon discrete graphics for lightweight applications and extends battery life.
AMD Zero Core — In a deep idle state, the new GPU consumes less than 5% of the power of full-fledged mode, disabling most of the functional blocks in this mode.
