AMD Radeon HD 8670M video card review: Specs | Hashrate | Testing – The graphics card for notebooks AMD Radeon HD 8670M belongs to the mass segment of mobile video adapters. The AMD Radeon HD 8670M is based on a 28nm GCN-based Mars chip with 384 shader cores, 24 texture units and 8 ROPs. The core of the video card runs at 775 MHz (825 MHz Boost) and supports DDR3 video memory (64 bit, 1000 MHz). It’s also worth noting that the AMD Radeon HD 8670M fully supports DirectX 11.1 and Shader 5.1 APIs.
The performance of the Radeon HD 8670M should be in the same range as the aging Radeon HD 7650M. Modern and demanding games like Crysis 3 can be played in low resolution and low details.
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.

Game testing
Total War Rome II. The test was carried out at a resolution of 1366×768 pixels, at medium graphics settings (1366×768 AF, AA), the result was 30 FPS, when the settings were increased to the high level (High, AF, AA), the average frame rate per second dropped to 25 FPS.
Metro Last Light. The display resolution is 1366×768 pixels, at medium graphics settings (Medium, DX10, AF, AA) the result was 11 FPS, when the settings were increased to high levels (High, DX11, 16xAF, AA), the average frame rate per second dropped to 9 FPS.
Battlefield 4. The graphics settings are average (Medium, 1366×768, AF, AA) 25 FPS, when the settings were increased to the high level (High, 1366×768, AF, AA), the average frame rate per second was 17.
BioShock Infinite. Testing was carried out at a resolution of 1366×768 with the game settings Med, High. The result is as follows, at high settings (High AA 4xAF) 17 FPS. With Medium AA AF, the average frame rate was 24 FPS. At maximum graphics settings (Ultra DX11, DOF, AA, AF) and a display resolution of 1920 x 1080 pixels, the result was, on average, 5 cd / s
